The Autonomy of the iPhone 5 Under Scrutiny

If there is a point common to the best black smartphones, and whatever operating system they boarded, it is autonomy. Indeed, race performance requires, smartphones increasingly struggling to show a satisfactory autonomy. This is an opportunity to review the latest in the Cupertino: the iPhone 5.

Not talking about the iPhone 5 compare to its competitors Android or Windows Phone, but after analyzing the various tests by iLounge and Macworld how does the battery last smartphone of Apple brand. The only comparison come from his elders, iPhone 4 and iPhone 4S.

It is therefore necessary, before rushing headlong on the results to see the iPhone 5 is no miracle on the side of autonomy and often worse than its predecessors, recalling the news brought by this iPhone 5 . Indeed, the iPhone 5 feeds a larger screen than previous models and is equipped with LTE, two innovations for the benefit of the user, but which requires more battery power always wanted one especially Apple impressive finesse (7.6 mm) and a weight lowered.

Let us initially on testing performed by James Galbraith site , the latter wished to verify the argument that Apple announced on its website up to 10 hours of video playback. The last three generations of iPhone updated with iOS 6, are present as well as the iPad 3rd generation and iPad 2 for a test that is to read 120 minutes of video in a loop until total exhaustion battery, in airplane mode, the screen brightness to 200 nits and the volume adjusted to two squares.

The result is clear, the iPhone 5 finishes last with 8:21 minutes is about 6% less than the iPhone 4S (8h54min) and 4% lower than the iPhone 4 (8h42min), it is therefore far enough away from the announcement of Apple, it is true rather optimistic, which was "until 10" video playback. The performance of the iPhone 5 is not bad considering that it has a larger screen, displaying more pixels than the iPhone 4 and 4S ship the same screen.

ILounge side, we pushed further tests and verified the independence of the smartphone on the 4G network AT & T and Verizon. Tricked by the words "up to 8 hours on 3G" for internet browsing, the iPhone 5 has taken 4 hours and 44 minutes surfing 4G AT & T (Verizon 5h15min) with two bars of signal LTE. So a disappointing score but as for video playback, the announcement by Apple is in the best case and depends on the quality of the network. An observation also applies to the results obtained for phone calls: If the iPhone 4S was pretty well up to expectations with 7h16min against 8h promised by Apple, the iPhone 5 was less with 6 hours and 15 minutes for Smartphone AT & T and 6 hours and 6 minutes for Verizon.

The side of good points, note that the iPhone 5 is better than its predecessor in terms of recording 1080p with 2 hours 30 minutes 2 hours 20 minutes against the iPhone 4S. Video playback on the other hand gives very different results from those of Macworld, the iPhone 5 doing better than the estimate of 10 hours of Apple with 11 hours 7 minutes with a volume of 50%.

If the result may depend on the settings and the video used, it should be noted that the results are generally below announcements Apple, showering optimism Wall Street Journal ( great battery life ) and Engadget ( Better battery life ? Actually, yes. ) who were enthusiastic about the autonomy of the new iPhone. The answer may come from iOS 6 if one believes the site Mashable that explains a simple Google search can see many testimonies of purchasers of iPhone 5 frustrated by the autonomy of the latest smartphone from Apple , joined by owners of iPhone 4 and 4S also note autonomy diminished since the transition to iOS6.
