Promise

The flagship of the range Nokia Lumia Microsoft is finally available and the price 549 euros ranks among the least expensive high-end smartphones in the market.

Reality

Windows phone a new device, this is the new platform for mobile phones Microsoft. It allows you to create applications for smartphones equipped with Windows Phone operating system. Appeared initially in its version 7, Windows Phone is currently in version 8.


Microsoft comes out with its new operating system for smartphones in order to compete with the two giants Apple and Google.

History, mobility at Microsoft

For a long time, Microsoft has mobile equipment. We had at first devices with Windows CE time; this operating system was a variation of Windows designed for embedded systems. In particular, it was used extensively in the Pocket PC (Pocket PC). This version of Windows has optimized for devices with limited storage space.

Then check the range of Windows Mobile. This operating system have  used on smartphones, PDA or Pocket PC. He came to compete with Blackberry and allowed to receive emails, use office suite, .. This mobile very similar to Windows as we know, with its famous Start menu. It has Was widely used a stylus instead of the mouse.

With the new touch interfaces, Apple has emerged, and its famous iPhone came to revolutionize the way we used to date mobile devices. This gave a severe blow to old Windows Mobile ...

Renewal: Windows Phone 7

Microsoft, in turn, radically changed its operating system to make this shift in mobility by offering Windows Phone, the first version is the version 7, released in October 2010. This is not an evolution of Windows Mobile, except at the version numbering (insofar Windows Mobile stopped with version 6.5). Windows Phone 7 has redeveloped from scratch and comes up with a new look, at first named "Metro," more refined, highly responsive and intuitive and rewarding structured information.
Microsoft is positioning itself at odds with its previous operating systems and offers different concepts for its new OS, as the exclusive navigation finger for example. Rather, it is the public that only for businesses.

To be allowed to use the Windows Phone 7-operating system, a smartphone must meet minimum specifications. These specifications ensure that the application will have a minimum of power, avoiding having too slow applications. The screen should be at least 3.5 multipoint inches, and that is to say, it must be able to respond to multiple simultaneous pressures and to a resolution of 480x800. The phones must also have provided compulsorily some equipment, such as having a GPS, have a camera, accelerometer...
Each phone also possess three buttons integral to its chassis. The first button will go back, the second to access the menu and the last to do research.

Windows Phone 8

This is most recently with the release of Windows 8, and the Windows Phone operating system has changed from version also upgrade to version 8. Microsoft's goal is to unify up the heart of Windows 8 and Windows Phone 8 to easily make links between them. Windows 8 is designed primarily for a tablet operating system, it seemed logical that Windows 8 and Windows Phone 8-share many features. Windows 8 is largely inspired by Windows Phone to create his style Modern UI, and it is now the turn of Windows Phone undergo major changes - Windows Phone 8 - to be closer to his big brother, Windows 8.

Many things have   shared between the two systems is the so-called "Shared Windows Core." Thus, it becomes very easy to create applications for Windows Phone 8 which require very little adaptation to run on Windows 8. This is one of the great strengths of Windows Phone 8.

Note that the Windows Phone 7 applications run on Windows Phone 8 is a good thing if you already own Windows Phone 7 applications and that they have not worn for WP8.
Windows Phone 8 is also more efficient thanks to the support of native code. It is thus possible to develop games in C + + using DirectX.

Windows Phone 8 brings more new screen resolutions: WVGA (800x480 pixels), WXVGA (1280x768), and "True 720p" (1280x720), with automatic adaptation of each.

The spirit Modern UI

Formerly known as "Metro" Modern UI is the name given by Microsoft to its design language. Rather than adapting the old interface of Windows Mobile, Windows Phone 7 it ​​was decided to start on a new design.

The name "Metro" was inspired by the shows that are in the subway stations and effectively guide travelers to their destinations. The displays are clear, precise, often minimalist and unadorned, for example, an arrow and an extensive 5 to indicate that this is where we will find the number 5 subway ... This is what should resemble the interfaces for Windows Phone. They should enhance the information and fluidity rather than heavy and loaded interfaces. The aim is to ensure that the user finds the earliest possible information they need and avoid unnecessary images or animations that might slow him down.
In this context, applications must be fluid and quickly respond to user actions, or at least tell him that his action have   taken into account. Sick of Windows or another where they do not even know if you clicked a button because nothing happens applications!

In 2012, Metro changed its name to Modern UI. Windows 8 and Windows Phone 8 applications each must follow the standards set by the principles of "Modern UI."
Modern UI, therefore, is simple, clean and modern. Features have separated Hubs, which are spaces combining information from multiple data sources. Thus, there are several hubs as Hub "contacts" where phone contacts but also Facebook, Twitter contacts we find ... We also have the Hub "Photos," "music video," "Games" "Microsoft Office," "Windows Phone Store" or the hub "Enterprise" which will provide access to business applications via a portal that businesses can customize.

Home screen emulator which shows access Hubs and applications
Home screen emulator which shows access Hubs and applications
Once back in the Hub, we have access to more information arranged in the form of a panorama. We shall see a little further what the panorama but I can already tell you that displays screens cyclically with a side-scrolling. Thus, in the Hub of contact, we arrive at first on the list of all contacts. Screen panorama that can drag with your finger allows us to get on the next screen the list of recent activities of our contacts, and a list of recent contacts. Moreover, so is the other Hub, the goal is to have an entry point that centralizes all information relating to a point of interest.

It is with these principles in mind that you need to develop your application. Feel free to observe how others are doing, there are often good sources of inspiration to see what makes the design quality of the application.

Windows Phone Store

The applications we create have been   downloaded from the Windows Phone marketplace, still called Windows Phone Store. They can be free or paid, allowing its creator to generate income. On the store, we will also find music and videos.

As we have already mentioned in the introduction, we will learn how to develop for Windows Phone without necessarily owning a Windows Phone. This is an important point, although it will be very useful to have one, and you can not quite start.

By cons, to publish an application on the Windows Phone Store, it will have a developer account. It had charged $ 19 per year, which corresponds to 14 €.
Now you know everything about Windows Phone; it has time to learn how to create great applications!

Windows Phone is a new operating system from Microsoft for Smartphone.
It comes with a new design philosophy of applications: Modern UI.
Applications developed are downloadable via the online store (store) Microsoft.

promise

Mobile Sosh first-smartphone operator, was a pleasant surprise. Six months later, the SoshPhone, which is distinguished by its 4G connectivity, takes over. The price is a bit higher but still moderate face to the proposed equipment. Careful design, large HD screen, 8-megapixel camera sensor and 4-core processor: the SoshPhone not the stigma of a low-cost model. However, what about its performance?

reality

Ultra lightweight and with 7.6 mm thick 132 grams, the SoshPhone seduced first glance with its elegant design. Only Sosh logo, which gives the impression of being (mis) bonded to the hull a bit cheap. The screen edges are relatively thin and skillfully blend into the glass that covers almost entire facade. The diamond patterns that adorn the back glossy black plastic deliver an embossed friendly. Fingerprints had diminished though still very present. Top and bottom of the mobile, slice a rounded shape that comes to break the side a bit harsh, rectangular smartphone. A pretty nice achievement, especially when you know that this is ZTE, who designed this model to Sosh. The great Chinese manufacturer is best known for the good performance of its devices that style effect. This could change ...

SoshPhone: it shines with its large diagonal

The strength of this mobile has  based on a large HD screen, bright, pretty good contrast and most vibrant without being oversaturated. Dimensions that the grip are a little less comfortable with an Ultima 5-homolog SoshPhone Bouygues Telecom, but that has a price to pay for a feast his eyes full and beautiful 5-inch diagonal. Power side, we find the same engine in the Android smartphone KitKat than its competitor: the famous 400 Qualcomm Snapdragon processor - Quad-Core 1.2 GHz - coupled with a healthy 1 GB RAM 3D performance SoshPhone are not as good as the 5 Ultima involved. big HD screen. It is possible of course to play on this unit if not to be too demanding. However, performance is still far from high-end model. Conventional use, menu navigation is fluid. Only downside, some irregular jerks, were observed in web navigation. Nothing is somber.

Autonomy: it has everything a great

Despite its large screen, the SoshPhone equipped with a high-capacity 2300 mAh battery (as the enduring S Grand Flex ... ZTE!) Displays the best of our comparative autonomy of smartphones less than 250 euros, rivaling the Sony Xperia M2. 20 hours in call nearly 12 hours on 4G or nine hours of video playback. Pass, the course of the day, should be child's play even abusing a little on the use. We regret only one thing: the battery is not removable ...

Satisfactory photo and video

Equipped with an eight-megapixel sensor, the SoshPhone allows for fairly nice pictures with a precision that goes beyond the clichés of Ultima. Limited to 720p video slightly lacking fluidity and stabilization is not perfect but without CELA truly penalizing. We would have appreciated that the smartphone had  equipped with a MicroSD card reader, but it will be satisfied with 16GB of internal memory (with a little over 12 GB dedicated to storing files).

The verdict

For 169 euros, Sosh offers with its new SoshPhone, a 4G smartphone with a sophisticated design, very well equipped and offers good performance especially in terms of autonomy. Despite its non-expandable memory - this is our biggest regret - this phone is to rank among the top models of the moment. So we are awarding it five stars well deserved.

Another device in the Galaxy range is the note: a blend of smartphone and tablet, which is also traded briefly under the name "Smart table." The distinctive features of the Samsung Galaxy Note is the size that clearly stands out from most smartphones. With a screen size of 5.3 inches huge Galaxy Note will be interesting for those who are a normal smartphone too small, and an ordinary tablet is too large and unwieldy. Precisely this user wants to satisfy with the Galaxy Note, and inspire especially Samsung.


Samsung Galaxy Note: The display

What's in the buyer of Samsung Galaxy Note in the eye immediately is the large display: 5.3 inches overall loose 1280 x 800 pixels. Thus, the display of the Samsung Galaxy Note has a pixel density of 285 pp. In order to make fullest the show altogether, Samsung installed in the lower housing a retractable pen with which you can not just quickly write notes, but also draw. Students, or all of the professional need to write many areas will love this feature. Due to the high resolution and a large display space, not only comfortable longer texts can be read and write, even surfing the Internet is an experience. On this point, the Samsung Galaxy Note stands out from other smartphones positive.

Samsung Galaxy Note: The procedure

In order to view the content on this large screen liquid, Samsung Galaxy Note installed in a 1.4-gigahertz reliable dual-core processor, which  supported by a 1024 megabytes of main memory. This enormous power is reflected not only on the home screen again, but also in graphically appealing applications. Whether this now is 3D games or high-definition video, the Samsung Galaxy Note will not disappoint its users. A 2500 mAh powerful battery ensures the Galaxy Note users a safe to get through your daily life.

Samsung opted for the Galaxy Note the Google Android operating system in version 2.3 Gingerbread out. The user is, therefore, free to pay the free Android Market with its lavish content each time a visit.

Samsung tried to make the Galaxy Note handy despite the large display. A smartphone that everyone can tuck in his pants pocket. With a mere 146.85 x 82.95 x 9.65 mm package, the Samsung Galaxy Note is still handy. Large hands should have no difficulty in operating the Galaxy Note.

Samsung Galaxy Note: The camera

Samsung Galaxy Note pictures
The Samsung Galaxy Note not only offers handwriting recognition and different ways to use the stylus, but opens up to take his photos with a smartphone and edit this thanks to the pin directly for all photo lovers a new way. To give users this option, installed the electronics manufacturers a high-resolution 8-megapixel camera that is not only possible but also each snapshot of each video in no time. By the way, the videos are with a 1080p resolution on the 16-gigabyte internal memory which can be expanded by microSD cards stored.

For sociable people, who are not afraid to present in front of the camera, Samsung holds the Galaxy Note a 2-megapixel front camera ready, perfect for each other talk.

Samsung Galaxy Note review: The tablet for your pocket
Whoa, smartphone too small, and a tablet is too large, the interest could be the Samsung Galaxy Note. Because with its large 5.3-inch display and the gigantic resolution of 1280x800 pixels, it is the perfect combination of both worlds - at least on paper. We have the Smartest looked exactly and showed the strengths and weaknesses of the Samsung Galaxy Note test.

Promise

True to its promise of renewal every six months, Sony launches the arena its new flagship, the Xperia Z2. Succeeding Z1 and Z1 Compact, this smartphone has revised and improved the best of them and has added some new features. Be enough to renew the genre? A gamble by the Japanese manufacturer because at first glance, Z2 and Z1 are as alike as two drops of water. We could test this new mobile a few days its commercial launch. Is it better than his elders and he has sufficient assets to compete with the M8 One and Galaxy S5? Verdict.

Reality

At first glance, nothing resembles the Z1 Z2. For its new flagship, Sony has done it again with his favorite material: glass, front as the back of the smartphone. For better or for worse ... The choice of material, noble and unusual among manufacturers prefer the plastic or aluminum, provides the latest Xperia real identity and an undeniably sophisticated design (quite masculine, it is good to specify it). Consideration of this choice, the smartphone is quite substantial in hand with a weight of just over 160 grams. That Sony has opted takes a little too much for our taste fingerprints and probably equally scratches the Z1.





Examining in more detail the smartphone, we see that the screen edges have gained finesse. Not enough on the upper and lower portions, according to us, but it is more attractive visually. Blow despite a larger screen (5.2 inches 5 inches against the Z1) Z2 remains at its dimensions, close enough to his elder. With his new piece aluminum frame, it even gained 0.3 mm in thickness and above the bottom of a dozen grams. Always Full HD, the largest slab loses necessarily solving -424 points instead of 441 points but as we have  said, beyond 300 dots per inch, you have to be very careful to note any                                                                                  difference.

Screen not bright enough for outdoor use

Z2 embeds multiple image enhancement technologies, including the latest Led Live Color, which expands the range of colors on the screen. Z2 and offers excellent quality display with more intense colors but quite accurate. By contrast, brightness and contrast, certainly not a bad thing, we were disappointed towards the competition. With a brightness of 406-cd / m² and a contrast of 1353:1, the Z2 is less than its predecessor Z1 and a lot less than the Galaxy S5 or One M8. Outside, the sun, the slab is the least readable of the three. As the viewing angles (despite the IPS panel), they are wide. Perhaps this is due to the glass seems thicker and more reflective than competitors.

Ultra powerful  is providing a beautiful autonomy

Let the good news! Z2 is not a simple aesthetic improvement Z1. With its Snapdragon processor 801 (four cores at 2.3 GHz), shows the smartphone as powerful as its chief rivals and can even boast boarding 3GB of RAM as the Galaxy Note 3 for a very comfortable managing multitasking. However, the best is yet to come. However, the Z1 Compact (mainly thanks to its "small" 4.3-inch screen) had known there six months, seduce us with its proper autonomy as the Z2 is now playing in the yard largely! With a small thirty-hour talk, he beat the record. Surfing on 4G network, it reaches ten hours and 12 hour's video playback, which is very satisfying ... However, unfortunately, fails to compete in the last two steps with the One M8 let the Galaxy S5 alone. The bottom line is that it will pass without too much trouble heading of the day or even two days by providing a little.

Always disappointing picture but excellent video

This is the side of the media to look for the main news on Z2, with mixed results. The 20-megapixel sensor remains; it is identical to that of Z1 with its qualities and defects. Some software improvements have made, but as the Z2 seduced video capture particularly well stabilized, as pictured it still does not show up to the performers. Stereotypes are not inherently wrong and rather natural colors, but they lack precision. As for the automatic mode (limited to 8 megapixels but now available in 4/3), it does not provide added value. Switch to manual gives access to 20 megapixels and many settings or HDR mode (moderately useful), but does not erase inaccuracies or gray areas in the upper part of the image.

Multimedia, news are emerging

With Z2 land 4K video, very well stabilized but, unfortunately, pretty useless if you do not have a compatible TV (Sony did here a bet on the future) and slow motion (Timeshift or idle) at a rate of 120 frames per second in 720p HD. App dedicated to this mode is quite handy because it allows you quickly to manage sequences to slow down. Another new Z2 adopts two speakers for stereo, more powerful and delivering quality sound. Not as stunning as the One M8 but the improvement is significant against the Z1! Finally, the smartphone incorporates technology active noise reduction and comes with compatible headphones (MDR-NC31EM) to fully appreciate his music in noisy environments (plane, train...). Moreover, without additional cost compared to the Z1.

 Top 5 Best Android Phones in 2014                        How to Clean Your Laptop

As expected, Apple has updated its range of smartphones with the launch of not one but two new models. Moreover, if the iPhone inaugurates 5c return to plastic while the first iPhone too has broken down intocolors, iPhone 5s remains the flagship of the Apple brand. It is the latter that we have concerned today.

Successor to the iPhone 5, which disappears purely and simply pass the catalog due to the introduction of the iPhone 5c, iPhone 5s shows the overall aesthetic and stretched format iPhone, choices that had debate is there is a year already. It is, therefore, at the heart of the iPhone 5S Retina screen of 4 inches.


Moreover, if the outside does not change-almost-not changing inside her bottom. New 64-bit processor, arrival of a coprocessor, management of the French 4G, flash new smart are many changes to the menu this iPhone also 5s  inaugurates a fingerprint reader in addition to natively run on iOS 7.0.

Design already seen 

Iphone 5s, therefore, incorporates the design of the iPhone 5 and found unsurprisingly anodized aluminum frame. With a thickness of 7.6mm, the iPhone 5s measuring 123.8 mm and weighs the same as its predecessor, i.e., 112 grams. The quality of the finish does not change, and it is outside the remains difficult to identify an iPhone 5 or iPhone 5s ... There are however a few subtleties: the LED flash is more impressive on the iPhone 5s as its size has doubled while the central button loses its famous square and finds himself with metal strapping according to the color of the device.





These evolving since the iPhone 5s now comes in three colors: silver, gold and gray sidereal.


The silver model has found with its white facade and back silver and two stained glass inserts in white. The center button benefits him a silver bezel. The black model is evolving, and we must now speak of a sidereal gray color: shade less black, the phone is supposed to be less fragile than its predecessor, so we hope not to see paint peeling in wear. In contrast, the middle button is here entirely black without any strapping, making the colors a little sad, at least in front.



 Taking the white facade and white glass inserts of the silver version, or model, called by some "champagne" has no side razzle-l'oil as one might fear. It is more, in our eyes, pink gold color than yellow gold. tastes and colors have not discussed and coordinated the home button has denoted strapping.

Hardware architecture and A7 processor

If it must be had admitted, outside this iPhone 5s are little or no change, the components of animating changing them significantly. Apple gives us indeed a smart A7. Moreover, if this change has  expected, the iPhone five has a memory chip A6, the big surprise comes from the support of 64 bit! Apple is the first to implement the ARM v8 architecture. Moreover, while Samsung still manufactures the A7 processors, the sworn enemy almost Apple, the Apple brand remains very little to say, as usual, on the exact characteristics of the SoC that has seemingly engraved 28 nm.

However, then the 64-bit in your phone, it used for? Ideally, one would be tempted to tell you anything. Alternatively, in the case of our phone, the iPhone is far from 5s board 4 GB of RAM, the maximum amount logically addressable by 32 bits. In this regard, the iPhone 5s has 1 GB of memory LPDDR3 like iPhone 5. Moreover, for this to be relevant should the iOS applications have direct access to memory that is not the case. Effectively with more registers, the A7 processor may be more efficient on some operations while it continues to be with two-execution cores.


This is not so much the 64-bit or additional records that the new architecture will explain the significant performance gains of the A7 meet its predecessors. Indeed, ARM designers have developed a new ISA (i.e., instruction set architecture) rather than extending the old as was the case on our desktop processors with x86, and its extension 64-bit (thank you AMD). Meanwhile, the cache size is increased, the latency of the second-level cache were lowered while the memory controller is more useful besides the size of the registers is probably higher as the instruction set supports new functions.

For developers, the arrival of 64-bit computing requires to recompile the application to receive a 64-bit version. An operation is almost transparent so by development tools supplied by Apple in this case Xcode. There will be some small alterations to do but nothing major though. The problem, however, is to end up with binary, i.e., downloaded files that include both 32 and 64-bit app, and using more storage space. In the future should allow XCode to compile 64-bit apps for iOS 7 and higher and 32-bit apps for iOS 6 only.

In his official communication, Apple refers to the A7 a count estimated at one billion transistors. Moreover, if the brand does not mean the operating frequency of the chip, it is identified at 1.3 GHz by our tools, as was the case for the A6 iPhone 5.

• co-processor: the M7

Apple M7 Another surprise materially iPhone 5s is the appearance of a co-processor: the M7. Are we back in time i486SX? Not quite. M7, if properly co-processor in its nature is not intended to accelerate mathematical operations on floating point calculations. It includes all the functions related to location in space: accelerometer, gyroscope, compass. Of course, these features could be incorporated into the A7 processor, but the idea of ​​M7 is left to applications using this type of functions continuous access to resources without consuming much energy as if it was the SoC who took care. Apple evokes here an energy of the order of the 6X face A6 processor economy. Right but the comparison has biased because not taking into account the
change in fine engraving while the mark has obviously been able to integrate the functions of M7 to A7. Unless, of course, to predict future products with A7 processor but without proposed by the M7 features.

Among the software features specifically offered by the M7 change detection status mode of travel. Passing a pedestrian moving in a motorized movement, iOS detects and offers more to join Wi-Fi networks surrounding. Another example: after a certain time where the iPhone has no move, the co-processor M7 reduced network usage to conserve battery power.

•  4G

 During the previous iPhone five did not take charge of the 4G  the new iPhone 5s does not commit this blunder. According to Apple, the terminal supports more than 13 different LTE frequency bands and the brand guarantee a speed of up to 100 Mbps. It is, of course, backwards compatible with 3G and Edge networks.

 The buttons for adjusting the volume and vibrate are on the left spine while the start button has located on top. Based iPhone 5s speakers and microphone jack and Lightning mini-jack connector found because they remember the connector for the headphones is now on the bottom of the unit. SIM card NanoSim size fits on the right side.

Beyond the parochial, the screen of the iPhone 5s offers a resolution of 1136 x 640 pixels at a density of 326 pp. Apple language, it is a Retina display with the usual oleophobic treatment. To the naked eye, the screen of the iPhone 5s seems very similar in its report to the iPhone five may be slight less

Apple Touch ID

While the design of the iPhone 5s would hardly differ from its predecessors, and if iOS 7.0 is now common to most iDevices, the one more thing is undoubtedly the arrival of Touch ID. After the Authentics technology, previously acquired by Apple, Touch ID takes the form of a fingerprint reader that takes place on the home button on the device, which also retains its function clickable back to springboard.


From a hardware perspective, the fingerprint reader is extremely well built and offers a resolution of 500 dpi and a reading of 360 °. The fingerprint reader is activated when the cerclage Home button detects your finger while reading area is protected by a sapphire crystal. From the start of the iPhone 5s, it is proposed to register the imprint of your finger you can store up to 5 fingerprints for each footprint, the process is carried out in two stages with several passages of the finger on the sensor for the finest possible acquisition. Moreover, in all cases it is not a photograph of your finger, which is stored in the iPhone, but rather a mapping.




Safety, the Touch ID data, can be found stored in a secure memory area A7 processor with encryption. If some smart guys have already found a way to circumvent the protection, nobody has yet succeeded in extracting the information stored on the iPhone. Information that are not available to apps and the rest are not sent to iCloud. One point that can get boring, because if Apple intends to generalize its fingerprint sensor several iDevices, it will automatically reregister said indentations on each device. Potentially painful, even if security is obviously reassuring to know that fingerprints will not roam on a server.





Level user, the implementation of Touch ID is quite striking. The recording process of the footprint is a bit long, but the release of the phone by simply affixing the finger on the sensor is an undeniable comfort: gadget outside, but once you get appreciable tasted. Where the reader fails to recognize, the finger is rare and just sit around for concern. In addition to the release of the phone, Touch ID validates iTunes purchases but only after giving his consent. Other securities were added by Apple: Touch ID is not available if the phone has not been unlocked for 48 hours or after a soft reboot of the phone. After five attempts to fingerprint recognition, you must enter your code number.

camera

Iphone5s 2The picture section is one of the areas where Apple has made ​​the most changes. Phone 5s hosted a new CMOS sensor, 8 megapixel but still physically larger. 15% more surface area to be precise, allowing Apple implement larger photosites (1.5 compared to 1.1 μ to 1020 μ Lumia). A real focal length equal to the iPhone 5 and 5c (4.12 mm), the iPhone 5s framework thus wider (30 mm vs. 33 mm). The optical block has also been revised; it now opens to f 2.2 (f against 2.4 above). Larger photosites and a generous opening is an ideal combination for capturing photos in low light.



Is this the case? IPhone 5s is better. Its sensor preserves more textures, compared to iPhone 5c and 5 (the two share the same photo module), and provides clearer images in low equivalent lighting conditions. Better than the Galaxy S4 but still below the Lumia 1020.

In good weather, there is also a lively dive, and softened colorimetry. Paying more attention, we note that the dynamic has improved, and the gradations of gray offer a bit more nuanced. Iphone 5s than its predecessors but still below the Galaxy S4 (slightly) and Lumia 1020, taking advantage of higher resolutions and so capture more details.


 However, it is an area where the 5s will everyone in it, is that of responsiveness. Ultra fast focusing, near-zero latency and burst, you hold well, capturing 440 images 44 s! The Lumia 1020 is ten feet underground, the Galaxy S4 lagging leg. Moreover, for a snapshot, this parameter responsiveness is essential. The major advantage of the iPhone 5s is not where we expected.

Side features include HDR and panoramic hands, better than ever thanks to the extreme speed of the iPhone 5s, but also a range of photo effects introduced with iOS7 here, and we can apply the shooting. Friendly, but you can not export them to PC, except to the email. Frustration that Mac owners avoid recovering their images with effects via iPhoto, since their cash iCloud.

Panoramic made ​​with the iPhone 5s

Note also that the Facetime HD function now enjoys a retro-exposed sensor, with there are also larger photosites (but Apple does not give more details). The record is a little less contrast but nothing flagrant well. To learn more about the abilities of the iPhone 5s photo.

Moreover, the video?

 Iphone 5s can indeed shoot in 720p at 120 frames per second, which when read at 30 frames per second slow sequence four times. The user can adjust from the terminal points of entry and exit from idle to give a striking depiction action. However, again, the slow motion (as we say in English) is not exported other than by email or via services such as Facebook, YouTube and Vimeo, with a loss of quality. Moreover, no more chances with the Apple TV: a slow motion video will not be played via AirPlay. Standard video changed, still in 1080p at 30 frames per second. The picture quality is superb, but it is unfortunate that Apple has not exploited its responsive autofocus to automate focus during movie shooting.

performance

To evaluate the performance of the iPhone 5s, we submitted a series of tests, with the latest version of iOS at the time of the test, in this case version 7.0.1. The results are obtained from an average of three measurements. All tests are not available on all mobile OS, and some smartphones may not be included in all graphs.

Geekbench 3

Geekbench performs a series of tests on the CPU (computing integers and floating point) and random access memory (bandwidth ...). The new version 3.0 performs its tests in single mode or multi heart. It is these results that we use, to the extent that all smartphones we've tested with Geekbench 3 are multi-core.




Iphone 5s then here by a short head the Galaxy S4: it is the only smartphone to surpass the 2,500 on the overall score, while it is yet dual heart according to benchmark tool. To compare the performance gain between the iPhone 5 and iPhone 5s, we have reproduced a table with the results of tests performed by details Geekbench 2 on 3 devices. The idea is to look at the same frequency, the effectiveness of architectures against A6 A7, both SoC operating at the same frequency of 1.3 GHz.

SunSpider 0.9.1

SunSpider JavaScript benchmark is the author of the Webkit engine. We use the 0.9.1 version to compare with maximum models still available. SunSpider performs a series of operations common Javascript and derives a score in milliseconds. Smallest result is best.




The result obtained by the iPhone 5s shows now reduced between the performance of a mobile browser and desktop gap: it runs the test even faster than the best Snapdragon 600 It should has been  noted that at the time of writing this test. we have not included smartphone Snapdragon 800.

GFXbench 2.5 / 2.7 (eg GLBenchmark)

Formerly known as the GLBenchmark, GFXBench makes a scene rendering in real time. We perform the test Offscreen mode to ignore the definition of the screen. Most smartphones have  tested with the previous version (2.5) we are rolling this test in addition to the new version 2.7.




Unsurprisingly, the GPU iPhone 5s still place above the Galaxy S4, and the GPU of the processor (Snapdragon 600) is certainly no longer the latest.


Version 2.7 is too recent for that we could use on all smartphones tested. On some models tested, there is again a fairly clear difference in favor of the iPhone 5s.


3D Mark


Mobile version of 3D Mark asked us one small problem: the Ice Storm modes Extreme Ice Storm and return the result "Maxed Out," the remaining rate on these two tests at 60 FPS throughout. We, therefore, carried out the test offscreen rendering on all smartphones mode, the only test to return a numerical result.




In all cases, it appears that the graphic part of the A7 exceeds almost all smartphones available on the market. The arrival of new models Snapdragon 800 should still make a difference.

 autonomy iPhone video 5s

We measure the autonomy iPhone video 5s with the following scenario: playing 720p video at MP4/H264 format played repeatedly on the default video player, until battery exhaustion. The screen is at its maximum brightness, its 50%. Wi-Fi has enabled and disabled Bluetooth.




The autonomy of the iPhone 5s in this usage scenario is substantially better than that measured in the same conditions on the iPhone 5 and 5c smartphone makes the soul after reading 7:30. The result is one of the best results, but remains below the Galaxy S4.

conclusion

With iPhone 5s, Apple renews at the top of its range smartphone, and if the design does not evolve beyond colors and we will spare our feelings about the gold model, physical changes are particularly convincing them. As for performance, the iPhone 5s immediately climbs on top of our tests while the responsiveness of the device is evident. Apple announces performances lined whatsoever for the processor or the graphics compared to the previous generation.

We take this opportunity to open a short parenthesis on iOS 7.0. The interface designed by Jony Ive is certainly client, as we have written in our feature on iOS 7.0, provided that this aesthetic is downright refreshing welcome, it does not upset the iOS experience that remains in the intuitive set. We thus find brands quickly, and we appreciate this rejuvenation sometimes cursing some details ... or some icons.





Fast, extremely well finished, this iPhone 5s is the first smartphone with a 64-bit chip. If the 64-bit architecture has no apparent immediate short-term interest for the iPhone, it will be different next iPad applications where content creation are more numerous, then it seems logical that one day land the Apple SoC as the A7 in laptops. Just in case ... a Macbook Air? Who knows? M7, the new co-processor centralizing information from motion sensors, is already used by some applications, but it does not seem to be at present a truly differentiating asset.




This is not the case of biometric sensor, or more accurately the fingerprint reader that takes place on the home button on the device. It is particularly well integrated and easy to use. Once configured fingers you get used to unlocking their smartphone without typing code and it simply with his footprint. The missed are rare and significant time saving. However, suddenly it is also said it is unfortunate that this center button is not smarter: the mere asking his finger above example could wake the device rather than pressing said button or the button start. Meanwhile, Touch ID works and works well. Remains to be seen what use will be made beyond iTunes purchases and unlocking the iPhone ... So as controversial or biometrics, and Apple still sign is still refusing to join the NFC.
Photo hand, if Apple does not do the bidding and the megapixel race, advances the camera of the iPhone 5s are net. Autofocus is frankly faster burst mode bluffing, and improved sensitivity in low light ... However, it generates some noise. For the video, we note the slow motion fashion and its implementation ultra-easy work with instead of export limited options.


Finally with 4G same for us ,iPhone 5s is accompanied by new accessories: leather cases including dock. Also, if he convinces us, despite autonomy that we would have liked more important, it is the price that we regret. Apple's strategy is not new, but the iPhone 5s bare expensive, very expensive. It costs 699 euros for the 16GB model (this ability should no longer be in our catalog in 2014) and 899 euros for the 64 GB model At this rate we would expect 128GB.

If it does not shine by its overall performance, the Sony Xperia M2 offers excellent battery life and a beautiful design.

promise

300 euros announced at MWC 2014 in Barcelona last February; the Xperia Sony M2 finally arrives much cheaper in stores. Offered 249 euros, it fits our category of devices less than 250 euros, which necessarily includes entry-level models. With M2, Sony does it offers us a powerful terminal environment to aggressive price range?

reality

Seen from afar, the Xperia M2 resembles a slightly cropped version of Z2. The design is similar; the effect of plate glass in the back is there (it is actually plastic!), The on / off button and silver photo trigger on the side of the device ditto. NFC logo on the back cover we add to this and really feel as a terminal 600 euros in hand. The comparison ends there, however: the processor is far less powerful - the fluidity of the system suffers a bit - it is not waterproof, and the camera is not of the same caliber (see below ). Z2 style low-cost version sum.

Super tough

8:15 p.m. with autonomy in communications, Xperia M2, is the most enduring of its kind smartphone - it
takes three hours longer than the second, the ZTE Grand S Flex. 4G surfing and video playback, it is also at the top, holding respectively 11:11 ET 10:12. Certainly within the upper models less than 250 euros (249 €!), It offers a full day of use which is far from being the case the rest of the competition.

Photo disappointing

Sony is a world leader in cameras and voice begins to enjoy ... at least in the high end. M2 because it does not shine by its performance! In automatic mode, the M2 delivers images at five megapixel 16:9 from the 8-megapixel sensor with a 4/3. The images are not free of stung, but the emphasis filter details night natural images: one has the impression that the designer has pushed the boost up in Photoshop. It should have added that an update imprecise points in low light and an optical free-repellent treatment - Fingers sebum accumulates on the front lens can affect image quality. Ultimately Xperia M2 offers troubleshooting photo camera, but it can not display true cameraphone

Display: bright but poorly defined

Xperia M2 is far slabs Full HD or HD ready: with a screen of 960 x 540 points and its resolution of 229 dots per inch, it is in the middle of the terminal to less than 250 euros, but does not standout. However, the panel offers good brightness (501:1) and excellent contrast ratio (1285:1) that make the M2 usable even in daylight.
