How much of an improvement is iOS 5.0.1 in your iPhone battery life?


I would think that there has been enough time since people updated their iPhone's iOS to see how much of a difference it made.  I'm ready for a 4S, but I'm also generally a little reluctant to jump in at release.  Are you noticing much of a change in battery life since Apple released the iOS5.0.1 update?

It didn't make much of a noticeable difference either for good or ill to me.  I'm sure that some people are having problems with batter life just from the amount of conversation on the subject, but I have not had that issue with my 4S.  I charge my iPhone every night, and so far I have yet to exhaust the battery even with pretty heavy use throughout the day at my office (where I use WiFi almost exclusively for internet connectivity).   When I'm not online for strictly work related reasons, I'm listening to music (or talking to Siri), and I get over 8 hours without a problem.  Again, I'm not discounting that some new 4S users are experiencing battery issues, and I may just be lucky.


It almost looks like a coin flip as to whether someone will have battery life issues with a 4S or not. has an article noting that they didn't experience the issue, while acknowledging that there are many reports from people who are.

Hi pcaulfield,

I've got an iPhone 4, not an iPhone 4S. I'm not seeing much of a difference. However, I didn't seem to have the issues that the folks with the iPhone 4S had in the first place. Hopefully they are seeing at least a little better performance now.

Cult of Mac had an article about it and they weren't very upbeat about the update:

iOS 5.0.1 Won’t Fix Your Battery Life, But It Will Forget Your Contacts
