iPhone 4S Battery Life Worse for 3G Data and Media as Compared to iPhone 4


Submitted by Dan; October 18, 2011
iLounge published their review of the iPhone 4S and provided a very extensive battery comparison test. In Apple's official specifications, the company claims the iPhone 4S has an improved talk time but worse standby time as compared to the iPhone 4. iLounge put the two devices to the test.
For tests with 3G Data, Audio Playback, Video Playback, and Video Recording, iLounge found that the iPhone 4S came in under the iPhone 4's battery life times. For Wi-Fi and FaceTime testing they found it to be similiar to the iPhone 4, and on Cellular Calls, they found the iPhone 4S slightly better. With 3G data was that while their Verizon 4S unit ran for the same time as the AT&T model (~ 5 hours and 54 minutes), they found the Sprint model to lag at 5 hours and 23 minutes. Comparisons across mobile providers may not be completely fair due to differences in signal strength which could impact battery life. In voice calls, they found the AT&T iPhone 4 and AT&T iPhone 4S to have comparable times of around 7 hours and 6-16 minutes. The Verizon 4S model, however, showed a surprising 8 hours and 27 minutes, while the Sprint 4S again lagged at 6 hours and 27 minutes. iLounge notes that the Verizon model may have shown 4 bars more often than the other two. From iLounge:
If you spend much of your day near a Wi-Fi network and only rely upon the iPhone 4S for web browsing and phone calling, you wont notice a major difference—unless youre thinking of switching to Sprint, in which case wed be a little concerned. Similarly, if you use 3G data, plan to record or play videos, or want to listen to hours of audio during the day, you can expect greater battery drain from the iPhone 4S.
Your milage may vary. You may see a huge hit on your battery life, you may not. - source: iLounge
