iPhone 4s Battery Life?

Ill keep saying it, my phone was great- 2% standby loss the first 2 nights.(At normal factory settings with cloud enabled!). The only strange thing was the phone was at 1% for about 20 minutes of heavy use. Dropped some settings to increase usage drain and things went downhill from there. constant 30% drain overnight. not to mention massive usage drain.

after dropping ALL settings- (location services, cloud, wifi, itunes ping, push notifications, etc.etc.etc) things have not gotten any better. I dont care what idea you can come up with- (diagnoistics, compass calibration, auto time set, stock ticker,iAds ) NOTHING is making it normal again.

I just did a full restore to new phone Ill get back to you guys but at this point I believe there is something wrong in the settings thats bugged.

My system status system log keeps showing "Unable to cancel system wake for 2011-10-21 09:20:12 -0400. IOPMCancelScheduledPowerEvent() returned 0xe00002c" Seems like something is not letting the phone sleep.

So im pretty sure its a software issue

Also there have been instances with my phone becoming warm while its in standby

Same battery issue with my 4S on the Verizon system. No help from Verizon but when I went in to the Apple Store it was fixed. They ran a diagnostic with their equipment (the clerks phone) and it showed that I had only used the phone for 1.5 mins. all day. He said that that was impossible and knew that it had been used more. He said that it told him that the sofware was corrupt and after backing it up, reformated the entire phone. Everything including the phones software was removed and reloaded. All total it took about 15 mins. So far, 2 days later, amazing improvement in battery life No longer want to return it. The phone would drop to nothing without much usage in 3 hours, now it lasts all day. This was done at the UTC store in San Diergo, CA. PS, you should turn off the wifi when you do not need it and are moving around town.

Is this different than doing a factory restore with Itunes ?

I get the same but the battery should be better. My last all day but still found the battery management is off by 3-5% plus their are lots of bugs on iOS 5

No it's the same thing.

I am not an expert but it sounded like he removed all of the software and started over. He said this could not be done at home and I did not have the ability to run this kind of diagnostics.

interesting, when i went to apple, they did the same test, and they just gave me a new phone...i'm not sure that fixed the problem though...maybe I need to go back to apple or something or just wait for the update...something is off thought thats for sure...

Apple will replace your iPhone but the problem is still in the iOS 5.

well hopefully they will fix it soon..thats all i can say...cause right now it battery life is like my droid pretty much...which is why i switched in the first place.

No the Diagnostic you can not do because they have the software to check it out but what they did they restore the ios5 on the phone which you can do yourself at home.

how do you know apple is aware of the problem? I mean who did you contact at apple that you told them of the problem you found, etc...

I can't give you names because I'm a developer but I can say Call Apple and they tell you they know about the problem.

@DocAaron - Its not a hardware problem have you not been reading these pages some people are on their 2nd phone and still reporting problems.

Have you not considered the process you went through with your new phone and perhaps that in 'your' case may have solved the problem. Did you restore onto the new phone from an Icloud backup or set it up as a new phone ?.

This in my book is a software issue however to what degree it can be improved I dont know as it does seem as though the new chip is taking its toll on the battery,

Ive done two DFU restores, one with an Icloud restore and one as a new phone both resulting in the same drain for me. Im getting around 5:30 usage on 15 hours standby which isnt massively bad like some people have experienced but I do think it should be better. With the screen on its loosing about 1% every 3/4 minutes im finding.

Ive configured it as per pages and pages of posts previous. To be honest im not happy with it id rather go back to my 3GS and wait for the 5.

Mac Beep Beep - are you suggesting this is some memory leakage within IOS 5 then? I've noticed in 3 days how bad this firmware update on my phone has been, the switched to the 4S and it's beyond ridiculous.

Just wanted to update everyone; they are aware of the issue and are working on it. I just got a phone call from Apple Engineering and was asked a series of questions. No ETA on a fix, but they are aware of the problem and will hopefully have a solution for us sooner rather than later.
