I notice no difference after the update. battery was good before and still seems to be the same. Glad it fixed some of the problems some of you were having but my 4S battery has been great.

It's hard for me to explain how much so because you don't know how I use my phone but let's just say by this time in the morning it's usually down anywhere from 96 - 94%! I know it's not gotten much usage yet, but like I said, it would have already dropped six or so percent by this time every morning. I'm stoked!
I never turn wifi off (ever.)
Screen stays at 60%.
Bluetooth always off.
Anyone else already experiencing a definite improvement?

Backup is only supposed to happen when the phone is plugged in. I turned off my photo stream last night to see if that helps the battery a bit. Turned off "raise to speak" this morning. Currently at 90% w/ 58 min of use, 2:49 of standby.
Right after the update to 5.01 (before turning off photo stream), my battery was down to 20% after 7:36 of use & 11:20 of standby. It's not awful but not great either.
Dude, I don't mean to be a dick, but it pains me to read your posts. So much broken English I feel like I'm having a stroke reading it.

is this user turn off all setting and leave a phone a side to get this result
i don't think iphone 4s battery could catch up this much
If a user did that, there would be a note below the Usage and Standby times stating the following:
"iPhone has been plugged in since the last full charge"
That note does not appear in that screenshot.
In any case, there are many different ways to "use" an iPhone and some of those ways consume more battery than others. I think it's entirely plausible for that user to have experienced the battery life that they noted.
