Q: iPhone 4s Battery Life?

Just bought the 4s, battery life is garbage.  I've tried all the fixes posted here, not much change. I hope they come out with a fix soon.  What is the point of having all these cool features in a phone if you have to shut them all off to keep the phone alive through the end of the day.

I had gone through all of the fixes described on the web with no luck, had reset phone to original settings numerous times trying to reinstall apps one at a time to see if I could find the culprit with no luck. One thing I always did was put my exchange email account on not ever thinking that it was the issue, GUESS WHAT, the exchange account was the culprit, now have over 40 apps back on phone, siri, location services, notification services all running wide open, 2 days battery just like my 3GS use to give. I have now tested the following: iPhone 3GS (sons) with iOS 5 (runs slower) with 4 email accounts (1 exchange, 3 POP) and around 40 apps, iPhone 4 (wifes) with iOS 5 with same configuration, iPad1 (wifes) with iOS 5 with same configuration, iPad2 (mine) with iOS 5 with same configuration, all had expected battery life of around 2 days. iPhone 4s with same configuration, battery life of about 6 hours, take off exchange account, 2 days. Has to be a problem with iOS 5 and 4s specific hardware. Come on apple, put your engineers to work and solve the problem...

So I went to the genius bar to get the operating system reinstalled - after a 10-15% drain every hour yesterday. (from 8:30am to noon I was down around 50% or less, after shutting off all applications besides the phone and then going to airplane mode to conserve power when it was down to 20%)...

The reinstall plus shutting off bluetooth, wifi, location tracking - i am at 2:10pm with 64% power...(holding for an hour!).. however, any browsing causes depletion ( I used it at lunch for 30min to browse and lost 7%)....

A reinstall worked for me - hopefully a real solution will be available... my gfs 3Gs is around 87% now

Add me to the list! I have phone for 3 days and battery life *****! Apple please solve this soon!

I would be more than happy to participate in this effort. Whoever the engineer is feel free to contact me. I will install the monitoring app ASAP.

All,

My question to all you wonderful folks here on this fourm is we have just spent 199+$ to buy this phone as this is expected to be the most amazing Iphone yet.

Does it makes sense for us to keep everything what this phone does at minium ( we are already running this phone at min like 800 mhz processor , 3g instead of 4g)

Now we are talking this a notch down of checking mail later , auto time set to be given away, etc .

Dont you guys think we want apple to come out and say whats going on , give us a status update if they will fix this issue or replace our phones.

I have 4 pop email accounts configured on my 4S. 2 were set for "Push" and 2 were set to "Fetch". I have changed all 4 to be configured as "Manual". I do not have Exchange and my batter life has been terrible. I will update in 24 hours.

Turn off icloud storage and backup.  That should prolong the battery life considerably.  If you want to extend it more, delete the account.  icloud kills battery, does not matter if it is an iphone or android. 

Another wireshark capture: My iphone has been in standby for the last 40minutes. I just ran a 2.5 minute caputre of wifi activity. My iphone spewed out 86 packets of wifi data within that time. A large number are probe request packets for the access point I am currently associated with. But the remainder are packets with no data. Again this is with no background apps, manual exchange, no icloud, etc. I might understand pinging the acess point periodically to stay associated but after 20 minutes of activity why would my iphone not be in an ultra low power mode. I would expect something more like every few minutes not every second or millisecond.

After days of dealing with the same battery life issues, disabling Siri's "raise to speak" option seems to have done the trick for me. 

Tried most things on here, gained some battery life, but just made a call for 19 mins it went from 34% to 27%, it got rather warm to, could be fast battery depletion?- also is anyone else finding the standby figure increases while your using it? Forgive my ignorance this is the first apple I have had. I can't seem to better my battery, I have reset etc and I built it as from new. New phone me thinks!

Add me to this. Charged phone overnight last night and only got to 4.30pm before battery was dead.

I wish people would stop saying the answer is to turn stuff off - that's not a solution in the same way I can extend the life of my car by driving slow and not going far.

The Apple website says I should get upto 200 hours on standby - 8 is a long way from that!

I can't speak for your battery use during phone conversations (may even vary from person to person based on carrier and signal strength). However, the Standby time is from when you unplug your phone and will ALWAYS increase. Usage time is basically when the CPU is running something (even if your phone's screen is turned off). So if your Usage time also increases simultaneously with the Standby time when your phone's screen is turned off, something may be amiss.

This is also my first Apple phone (though we've got a few iPods in the house).

Actually, its more like saying that you can extend your car battery life by not keeping the high beams on at all times.  Switching off certain functions may not be the ideal solution, but if you don't really need the function anyway (such as the "raise to speak" option), I don't think it's a big deal.

But I *do* need those functions otherwise I wouldn't have them on in the first place

I fully accept that by using location services, bluetooth and 3G, etc that I won't get 200 hours standby - but I expect to get more then 8!
