My 4S lasts about as long as my 4 did (which in a poor signal area isn't very long). I don't bother to turn stuff off like everyone else (if I wanted to fiddle with settings to get longer battery life I would have gotten an Android phone). I just carry around an extra battery pack and charge my phone during the day.
 
Under setting/general/about/diagnostics & usage/ (select, don't send)

I had very poor battery life as the dam phone was sending diagnostic reports to apple every 10 seconds, the phone also started to get hot some times!

It is sending reports to Apple because some apps are crashing every 10 seconds! I found several dozens of crash entries in my Diagnostic Data. I have the send automatically enabled as I want Apple to have those reports and fix the damn OS and Apps.

Some of the things under the Diagnostics section aren't necessarily actual crash reports caused by a bug.

A lot of mine are from the OS running out of memory (mostly due to Safari) or because an App has tried to do something in the background for longer than 10 minutes.

Those phones were about 4x thicker too! lol

Yeh my first sim card was the size of the credit card. No pop outs there
 
My battery life is horrendous when I get down to about 2 bars reception (AT&T). This is a time when it would be nice to force the phone to E, like I normally would. Otherwise, battery life has been ok to good for me. Definitely not as good as the 4 - my jailbroken 4 (with 4.3.3) was unreal.
 
pure example of cutting corners to save money by apple.. they know damn well they should have put an upgraded battery in the damn things but instead they choose to not do it so now they acing heat

Everything turned off and still worse than my old 3GS. Makes me said because everything else is amazing.
 
Mail is likely a battery drainer

Its push email. When I turned it off from my corporate exchange, and set it to every 15 minutes instead, battery life improved dramatically.

That was my issue also. I have 3 email accounts set up on my 3GS with iOS 5 . I turned off Push and set it to fetch new data hourly. Big difference.

I also suspect mail being one of the issues. We have 2 3GS. For a long time, our phones survived about 2 days before a need to recharge. Since about the time of the 4.2.3 upgrade, we both suffer of a battery drainage. These days, we both have to charge our phones during the day so they don't die before coming back home. Interestingly, one phone has Timezone support on, the other one is off.

One experience that points to a mail issue was the following situation:
I have 4 mail accounts (3x IMAP, 1xExchange). They are configured to Fetch manually (no push). last week, my company mail account (using Exchange-configuration on the iPhone) was in a maintenance mode and my mail could not be synced. When opening this mail account, it tried to connect without success (I think it tried endlessly). That's why I closed the mail app. However, the battery drained within 4 hours and the phone went hot. This indicates that some (probably) WLAN activity was going on. This issue occured with iOS 5 on my 3GS.

So, mail is likely a battery drainer, likely not the only one.

My 4S has hundreds if not thousands of entries in the log. The list is so long that you get tired of scrolling down before you run out of list. At least I know why I went from 16GB to 32GB memory ... so I can keep a log of all the times my phone crashes. My wife has a 4 (my old one) and it's in a virtually identical setup except she only has three entries in he crash log.

I wouldn't describe my battery life as terrible, just disappointing as I was expecting better! It drops about 1-2% an hour when left overnight giving me a standby time of around 75 hours ... well short of the specification!

The other issue I'm seeing is the phone "using itself" overnight, typically 25 minutes of usage when all I've done is unplugged it gone to bed and checked 7-8 hours later when I get up!

I think I'd like to try a DFU restore but not sure what I have to do ...
 
I have noticed dramatic battery use in all three of my 3 family plan 4S' over the iphone 4'.
We have reduced location services, etc. etc. Hoping for a fix. Talking while plugged in is like old land lines.
Is there an app where I can dial by rotary touchscreen? LOL

Still love all 15 iPhones.

The only crash is when pulling up photo and MMS it then adding text, when pushing send it does not send then goes back to home screen.
Tried resets as well.
I guess I'll ask Siri.
 
iPhone 4 battery drain

I had the same issue with my iphone 4 after installing iOS5. I went to the Apple store thinking there was an intrinsic problem with my battery but they ran diagnostics and the battery was fine. They recommended I wipe the iphone and set it up as new again which I did. I am happy to report that the battery life is much better now. One note, they recommended that I not restore from a previous backup because the backup likely contains the bug. So I set up the phone as if it were a new phone. The annoying part was I had to re-load all my apps and re-organize all the folders but it was kind of like having a garage sale - I was able to get rid of things I wasn't really using and the phone is running much better now.
 
Battery Life

I will be happy to have them install the software on my new 4s. I upgraded after buying a verizon iPhone 4 when they were released. I must say the 450 bucks to upgrade is a little disappointing after my battery issue. But I hope they will resolve the issue, and will let them monitor my usage to help....sam
 
I had this problem, but it doesn't do it now. It turned out to be a calibration issue for me. To recalibrate:

1) Drain the battery until the phone shuts off on its own.

2) Charge it non-stop back to 100% (Should take 2 - 3 hrs)

Did this last night but it only took me an hour and 40 minuets to fully charge it. Is that a bad sign?

Yeah - mine is growing fast too. Many of these are due to out of memory but not majority. Looks like iOS5 got out on not so solid footing. Restore doesn't help - I have tried it - as soon as you install one other significant app and use it along side Safari the crashes and low memory issues start. Getting dropped to lock screen while watching Netflix is the most irritating thing that happened to me several times now.

I wonder if 512Mb is not enough and may be Apple should have shipped it with 1Gb - but then I wonder how iPad 1 was getting away with 256Mb - may be this is a iOS5 bloat issue.
 
I love Apple, truly. This is above and beyond what I expect from any customer service, even Apple. I'm impressed.


They produce one phone every 1.5yrs, they can't afford for it to be a turd. Lets be real.
 
This is a total mystery. The battery life of my 4S is significantly better than it ever was for my 3GS. I've been wowed by the battery life in fact and I use it gratuitously with lots of stuff turned on. I hope some pattern emerges which will help Apple track down the cause of the battery drain some are experiencing.
 
I've held out for two weeks now thinking its just a software bug. But coupling the fact that Apple engineers can't figure out the problem with the fact that it affects some users tells me its a hardware defect.

Some days i have great battery life and some days its absolutely terrible, with the same usage. I'm sure Apple is scrambling to figure it out and hopefully I am wrong and its just some glitch, but surely this would affect every user. M

Whether it be something major or just a bad run of batteries Apple will have to rectify the situation. My concern is that even if it's a hardware issue they will still put out an update claiming to fix the problem (AntennaGate anyone?).

This is what leads me to think it's a software bug. If it's hardware there should be no "good days". But if the software is inadvertently switching something on/off then you can have good/bad days depending upon the type of use.
 
People saying "no problem, you should just turn off your services, etc etc.." kinda remind me of the time my sister went into radio shack to return her EVO and the manager told her "just buy extra batteries and carry them".. "make sure you get the "app killer" or all these hoops for the EVO.

I know more than likely a lot of you guys are technically savvy, but as big as a company apple is, they shouldn't depend on people trouble shooting their devices to optimize battery performance. I think this is why so many people like their devices to begin with.
Welp, there goes the Consumer Reports recommendation again.
 
But it isn't just the 4s which has this issue..

My iPhone 4 which I've had for a while now has battery issues since the iOS5 upgrade..
