The autonomy of the iPhone 4S compared to the iPhone 4

What is the iPhone 4S battery worth?
compared to those of the iPhone 4? On theforums, speculations on the autonomy of
each machine is going well.

According to Apple's official specifications, the firm indicates that the iPhone
4S lasts longer in conversation, but for the rest, the previous
model would exceed the 4S, the iLounge site has
carried out a comparative testcomplete (and rare) autonomy of the iPhone 4S
with the iPhone 4, of which here are the lessons:

When tested with 3G data transfers, audio playback and
videos, as well as video recording, it appears that the autonomy of
the iPhone 4S is less compared to that of the iPhone 4. Regarding
Wi-Fi and FaceTime, the results are approximately the same, and for
When it comes to classic voice calls, the 4S is slightly better than the
4.

The following graph brings together most of the results on phones
d’AT&T :

The tests were carried out on American models, in this case
attached to operators AT&T, Verizon and Sprint.

Interesting fact: during tests in 3G, the Verizon 4S model turned
as long as the AT&T model (around 5 hours 54 minutes),
but the Sprint operator model showed signs of weakness at 5
hours and 23 minutes. However, comparisons between suppliers can
be misleading, because the power of the networks is not necessarily the same, and
the protocols used are different.

On voice calls, the results show that the iPhone 4 and 4S
of AT&T are almost identical, around 7:06 and 7
hours 16 minutes. However, at Verizon, the 4S model has demonstrated its
power with a nice 8 hours 27 minutes, while the Sprint found itself
well despite its name at the back of the pack with its 6 hours and 27 minutes.

For recording and playing media, the Iphone 4S took a hell of a
kick in the teeth. For video recording, it is obviously necessary to note
that the adopted resolution is much superior to its predecessor, which influences
of course on battery life.

Ultimately and very logically, iLounge indicates that consumption and
comparison with the previous generation will depend on your profile
of use: "If you spend a good part of the day near a
Wi-Fi access and you only use your iPhone 4S for
internet search and phone calls, you will not notice a
big difference. …Similarly, if you use 3G a lot,
recording or playing videos, or if you want to listen to
hours of music per day you can expect to charge your iPhone
4S more often than 4."

We also conclude from this US test that the power requested by the networks
also affects battery life

In any casethe complete test(in English) is worth a look,
since it explains, and proves (by dint of images) the hypotheses which are
progressed during testing.

is as optimized as possible and our iOS 5 tutorial concerning settings

And you then, have you noticed a notable difference between the iPhone
4 and the 4S in terms of autonomy?
