I'm not trying to troll or anything, but I noticed a MASSIVE improvement in my battery life. On 5.0.1, my battery would drain 1 percent around every 3~5 minutes. Now with a "restore and update", I'm getting around 7+ minutes per percent.

Here is mine with 5.1. I restored, updated then reset settings (which icloud has saved) to default and my battery life is amazing.

I have noticed lately that almost the entire time that I am at work, my battery will stay at 100%, even after making a few calls and some light usage.

It does seem to lose about 20% over night.

Usually, it's at 50% each day when I charge before work.

When sleeping:
iOS 5.0.1: 100% to 86%
iOS 5.1: 100% to 96%

Daily use:
iOS 5.0.1: 100% to 20-30%
iOS 5.1: 100% to 50%-60%

I am not sure about when sleeping since I have it plugged in but my daily use is about like yours depending on how tough I use it that day. At the dealership you can get bored with no ups so usually surfing the web and what not can bring it down quicker than usual of course.

I find it far worse...

Last night it was fully charged at 1am - went to sleep and woke up at 8am and it was down to 57% with NO USAGE.

It's infuriating as I can't even listen to music for 6 or 7 hours at work like I used to otherwise the battery is dead before 4pm.

Crazy :( Looks like I'm back to iOS 5.0 situation and turning everything off that I would actually like on just to save 15%.

Hope they sort this out, or ship iPhone 5 with a far greater battery, this is becoming HTC standards as of late :mad:

What exact steps did you take to do this please? I use iCloud backup on my 4S/iPad (the iPad battery is fantastic but my 4S since update 5.1 is absolutely shocking). If you manage to get a few mins extra per % I could really do with that!

Thanks

After a restore from iCloud go to settings -> general -> Reset -> and reset all settings. And then dont touch the settings you dont absolutely NEED to adjust (especially screen brightness)

The battery life on my 4s has improved substantially with the 5.1 update. 5.0 was horrible for me, and 5.0.1 wasn't much of an improvement. I never reset my settings or started fresh since I got the phone, just doing OTA updates. I can say now that I'm finally happy with the battery life of my phone, which I wasn't able to do before 5.1.

I've installed 5.1 (upgrade from 4.3.5) on an Iphone 4. From what I can see battery life is about identical to what it was before. It should be noted that I don't use wifi and bluetooth that much. However, since updating to 5.1, I've turned on iCloud which I use for synching contacts, calendars, and bookmarks. A nice thing I like about the new update is that web sites seem to load much faster than before for certain types of content. Safari doesn't "freeze" when loading large or complex web pages with lots of graphics. Overall, I'd give 5.1 a thumbs up. It's a hundred times better than I expected (especially after reading so many negative comments on the web). :cool:
