Performance characteristics of smart phones..


Performance characteristics of smart phones of Apple iPhone 4 and HTC EVO 4G. The last creation of Apple against the first 4G сматрфона in America.
After has been officially presented Apple iPhone 4, developers of Apple decided to remove back a row of widely known models 3G S, and to move forward to following generation. But if you do not carry a medallion in the form of heart with Steve Jobs's photo inside, whether has in this case sense passage on iPhone 4?

Pregoing models won many competitions, and the various categories, the new model met more severe competition, than it was earlier. Whether has now Apple the conclusive superiority in the market смарфонов? In this article comparing of performance characteristics iPhone 4 and its most serious contender of HTC EVO 4G on the basis of Android is resulted.

The display
The winner: Apple iPhone 4
This year company Android products move in a direction of magnification of resolution and the size of the screen, it is clear that for iPhone the new decision in this area was necessary completely. And Apple gave such decision. 3.5 — inch, having resolution 960x640 пикселов LCD the screen iPhone 4 has in four more пикселов, than in the previous models, namely 614.400. As comparing, 4.3 inch screen of HTC EVO 4G physically has the big sizes, but resolution 480x800 пикселов, and total пикселов 384 000, nevertheless concede iPhone 4. A bolshee amount пикселов on the smaller screen give iPhone 4 improbable purity and definition thanks to density пикселов. The certain part of buyers can prefer EVO 4G for больший the size of the screen, but the majority nevertheless prefer high detailing and clearness iPhone 4.

Portability
The winner: Apple iPhone 4
4.3 — the inch screen gives to relevancy EVO 4G. But very often it is not absolutely convenient to carry such monster in the pocket. Besides that the HTC is thicker and heavier, it has a thickness of 12 mm in comparison with iPhone 4 - 9.3 mm, and weighs 170 г in against 136 г at iPhone. IPhone 4 here out of not a competition.

The processor
The winner: the Drawn game
Both iPhone 4 and EVO 4G are equipped by high quality processors. IPhone 4 it is equipped by the same A4 the processor, as iPad, in EVO 4 it is applied fast Qualcomm Snapdragon, working with impressive frequency 1GHz. But comparative tests showed that on iPhone 4 village boots on 37,5 % faster, than on EVO 4G. Certainly, various operating systems, and many other factors, do such test far not scientific.

Memory size
The winner: Apple iPhone 4
In Apple always neglected storage expansion slots microSD, and in iPhone 4 from this point of view changed nothing. But at the same time it is necessary to tell that iPhone 4 offers the same amount of the maximum storage, as well as EVO 4G, but for smaller money.

EVO 4G is issued with installed microSD by a card in the size 8Гб, but potentially you can increase memory size to 32Гб by means of a card большего volume. Unfortunately 32 — гигабайтные cards still remain a rarity, and you are forced to pay for it at least $200. At the same time, less expensive iPhone 4 ($200) are issued with the built in storage in volume 16Гб, and the extension to 32 Gb manages to you only in $100. Owners of smart phones who want to receive the maximum memory size, should pay $300 for the Apple device, and $200 for HTC plus of $200 more for SanDisk that in the total makes $400. At the same time users with whom the minimum memory size arranges, should pay the identical price ($200) for both devices, but with iPhone 4 they receive 16 Gb of the built in storage, and with EVO 4G only 8Гб. IPhone 4 wins with the big lift-off.

The camera
The winner: HTC EVO 4G
Both smart phones, both iPhone 4 and EVO 4G are equipped by video cameras on the back panel for pictures, and as cameras on the front panel for video conferences. EVO 4G gives more clean view, doing 8 megapixel pictures, in comparison with 5 megapixel at Apple, the HTC on the front panel has 1.3 megapixel camera, and Apple only 0.3 megapixel VGA the camera. At the same time it is necessary to tell that more the high resolution not always means better quality. EVO 4G it is equipped double LED by flashout, in comparison with one LED flashout at iPhone that potentially should mean better quality of pictures during shooting in a night-time.

Cameras of both phones are capable to write down high resolution video 720p, but iPhone 4 can write down video with frequency of 30 frames per second while EVO 4G it is capable only of 25 frames per second.

Connection
The winner: HTC EVO 4G
That that EVO contains in the title «4G» it not simply randomness. Actually it is the first smart phone in the North America which it is capable to work in a high speed network of a class 4G which potentially should put an end to slow loading, on a habit all ассоциируемую about a web surfing on the mobile device.

How much faster? The HTC states that in 10 times, but such statement is based on comparing of average indexes of speed of much slower 3G networks (from 600 Kbps to 1.7 Mbps), and high indexes of a network 4G (from 3 to 6 Mbps). The first tests confirm at once speed 3Mbps in a network 4G, but such speed was an exception, but not a rule, and in the core connection was slower. Tests of speed PCWorld on smart phone EVO 4G, confirmed the same results.

It is necessary to recognize, what even 3 Mbps it is more than you could expect from class phone 3G, and EVO 4G already now can do those things which iPhone 4 only intends, for example a video conference without Wi-Fi connections. «Ten times» it certainly advertizing exaggeration, but the majority of users will be quite happy in the speed "twice" большей.

EVO 4G as it is capable of interesting things which force to envy owners iPhone 4: for example function Wi-Fi of a point for joint connection with other devices, such as notebooks, and even other mobile phones.

Duration of a battery power
The winner: Apple iPhone 4
The battery power never was strength of the first smart phones of Apple, but the company insists that this time indexes are refined, and the same 4G the modem which puts EVO 4G on a step forward from the point of view of connection, is its Achilles' heel. HTC did not let out gross data concerning duration of battery power EVO 4G, but practical tests showed 6 business hours in 4G while Apples declare 6 business hours in 3G networks. Talk time also most likely suffers, the HTC declares 360 minutes for EVO 4G while the Apple declares 420 minutes for iPhone 4.

Certainly it is not so important, but EVO 4G is equipped by the replaced battery, and iPhone 4 is equipped by the built in constant battery that for HTC means possibility of alternate usage of two batteries, and gives some advantage. Though within the limits of a city it is difficult to meet the owner of the smart phone who has a necessity for battery recharge for flow for, travelers on big to distance can probably estimate such possibility.

Operating system
The winner: the Drawn game
As to both operating systems iOS and Android it is necessary to mark that both of them have the advantages.

The Apple iOS undoubtedly does not suffice the floppy open ecosystem Android, allowing to function to the game console emulators blocked by Apple, but the Apple benefits from the point of view of a choice, giving 255 000 applications from indirect vendors while Android gives a choice of all from 70 000 applications.

Technically tempted users undoubtedly estimate absence of various restrictions on Android, the majority of users will be found by many advantages in a huge choice of applications and ease of usage of Apple iOS.
The general winner: Apple iPhone 4

Certainly both smart phones are impressing. Nevertheless iPhone 4 from Apple is more successful product, than HTC EVO 4G. Why? Principal advantage of HTC is 4G connection which as appeared, offers less advantages in speed during real usage, than on a paper and as lags behind from the point of view of duration of a battery power. The HTC as has small advantages on indexes of resolution of video of the camera, but smaller frequency – 25 frames per second, minimizes this distinction. IPhone 4 is more compact, has большее screen resolution, and gives больший memory size for the same money.

Site mac with sometimes very...

Site Mac with sometimes very exact history of predictions, now states that Cupertino now tests considerably different three prototypes of following generation iPhone.

The first prototype, allegedly, similar on Blackberry iPhone 5, its principal singularity is advanced physical keypad-SLIDER QWERTY for the fast press. Obviously such device is directed on business of users, and текстеров.

The second prototype? Simply spectral shock as this model iPhone 5 should be an equivalent to all models iPhone — with iPhone 3G on iPhone 4. The design will remind very strongly design of already existing model iPhone 4, only увеличиннаяя duration of a battery power, and the camera with нарощенными мегапикселами. Presumably, phone will be equipped by new two-nuclear processor A5 which will debut on iPad 2.

About the third prototype it is not known, but it can be 4-inch iPhone 5.
NFC

This information is quite confirmed. It is not a secret that NFC (near-field communication) is new hot technology which allows to use your mobile phone as a mobile card, for this purpose it is necessary to keep phone at arm's length no more than 20 sm from an accepting surface. Many new devices include this technology, and most likely iPhone will be among them.

Dual GSM/CDMA and 4G
Already now it is known that Apple equipped the future devices such with functions, as dual GSM and CDMA. It means that new phones of the company will work in networks CDMA of such operators, as Verizon and Sprint, as well as GSM operators, such as T-Mobile and AT&T, directly from a box.

Quite probably that iPhone 5 will support HSPA+высокоскоростное connection (it is evolution GSM), some disputes concerning support LTE working inside 4G of network Verizon are conducted. AT&T builds own network LTE as.

Physical keypad QWERTY discredits everything that Cupertino reached in мультитач and iOS. In components, it was historically added that the Apple presents the updates iOS with an interval in one year, and most likely iPad 2 will not have radical differences from original iPad, but it will be more modifed version. Most likely iPhone fifth generation, will be also more modern version iPhone 3G. Most likely it is necessary to expect quiet growth — for example a jump to the two-nuclear processor and the increased duration of a battery power — for iPhone 5, and other evolutionary jump in the person iPhone 6 then should follow.

Ipad ipad is the first...


iPad
