iPhone 4s Battery Life?

My new battery life after a fresh restore and charge :/ this is terrible-

I think I found the answer to the baterry drain. I been testing setting y setting to see whats causing the poor battery of my iPhones. I been testing my iPhone for a week now and two days ago I turn off the cel network search settings under Location Services and my battery was able to hold for a full day and a half and 7 h off heavy usage (email, texting, phone calls, Facebook, twitter). The main thing was that under standby there was almost no battery drain. I think that this setting was causing my phone to die by 5 pm every day. (I start my day at 6am). Now I'm able to last until the next day with out charging it!

This is what I did a week ago

1. reset the phone to factory settings with the computer ( I had to download the iOS since I did the last update via OTA)

2. Setup 2 exchange accounts with PUSH, and iCloud with PUSH, iTunes match

3. Turn off ping

4. Turn off all system service in location services, exept compass calibration ( I use it with waze).

5. My apps locations services I left on the ones I know I use

Let me know how it goes!

I've tried so many different suggestions and still have terrible battery life. I even went to the Genius Bar and they swapped it for a 'new' iPhone (which looked suspiciously refurbished). This one is even worse! Like they swapped it for one somebody had already brought back!

I went to sleep last night with around 55%(ish) battery life, woke up to 4%! This was after a full charge over night the day before. iPhone wasn't even used yesterday, yet the usage says 14 hours use since last full charge.

Now I'm no Carol Vorderman, but from 9am to 9pm isn't 14 hours and in that time it drained the other 45%, it then lost 41% doing sod all last night. Add this to the fact I didn't even use this phone yesterday (I also have a blackberry - which I used to curse its battery life but lasts 3 days) then you have to wonder on the credibility of the usage stats. At the Genius Bar, they had my stats on their iPad. Completely different to the stats on my iPhone yet they said it was normal.

Awaiting a call from Apple later today, gave them my BlackBerry number just in case...

Why is this terrible?

1. You are on pace for over 40 hours of standby
2. You have no providioned SIM installed (SOS only) so your phone is constantly searching for a signal, which further drains the battery.

Not suree you have any problem at all.

Well that was just the room I was in has no service but to be honest my macbook has better battery life. 😟

Hmmmmm...... I doubt your Macbook will last 40hrs on a charge.

If you are in a poor reception area, battery life will suffer as a result.

To be honest, most of the folks in here reporting problems would be thrilled to get 40 hours out of a charge. There are loads of good suggestions in this thread on how to maximize battery life, but to be frank, unless you start to severely restrict the functionality of the iPhone, you aren't going to do much better than you are now.

If we were to assume 1hr lasts me that last 20%, then I can conclude I'd have used 9 hours, 35mins used, 11 hours, 20mins standby(?). Is that decent? Could it be improved?

This thread is getting ridiculous! Apple should now shut it down.

Your log would make a very good advertisement for Apple!

Thank-you very much! If Apple did ever want to use the info. in my log, they could contact me.

I appreciate your very detailed report.

The best I have found is to limit my 3G use.

Leave 3G off most of the time until I will use it and turn it off right when I'm finished.

I use wifi extensively.

To send or receive pics you need 3G.

Try to go 2 days without your iPhone. Say Saturday and Sunday. Just try it.

Yes, that is rather good for a very heavy user. Note that all the battery drain things have to be added up, and consider the 'standby' time as 'background use', and don't forget to add that into the total battery drain. EVERYTHING you do on the phone takes battery power, and if you are doing more than one thing at a time, then those must be added together, and then the standby added to that.

I back up & restored from iCloud anyway :p Then calibrated. I'm getting basically the same battery I had as in that log above, though I'm in process of making another log since restore.

I found a possible cause / solution - in my case one of my contacts was failing to sync with iCloud, so the contacts app kept trying again and again. The phone even got too hot to comfortably keep in my pocket.

Solution for me:

1. Exported all my iPhone contacts using My Contacts Backup.
2. Deleted all contacts from iPhone and iCloud.
3. Broke the synchronisation link.
4. Re-imported the backed up contacts to the iPhone.
5. Recreated the iCloud synchronisation link.

Hope this helps some folks.

I don't get it. You buy the phone to use it. When you use the device it consumes battery... All electronics do this. Putting the phone into airplane mode (turning it into an iPod touch) isn't a solution. Poor network service consumes more battery. More data usage consumes more battery. Using the camera, reading eBooks, listening to music... all these things will consume the phone's battery. That's what it is for. So what if you charge it every night? I've had to charge my phone every night since I've had a smartphone. That's with BB, Windows, (old windows mobile), Android and the iPhone.

My suggestion: stop stressing the battery so much and enjoy the device by using it.

If the phone is drastically bleeding battery then take it to Apple and have it replaced.

This isn't meant to be a rant but after 830+ pages of the same topic and arguments about what's good or not the situation is getting a bit ridiculous. That there is not Apple's fault.
