Q: iPhone 4s Battery Life?

Tried that, still sucky battery life.

Hi,

I'm running an iPhone 4S white 32Gb, on the Three network in the UK. I was originally suffering from really bad battery life and after reading a few articles on the Internet I stumbled upon a thread in the forums on Macumors.com. The thread discusses the use of location services to set your time zone automatically, this setting can be found in System Preferences/ Location Services/ System Services (scroll to the bottom)/Setting Time Zone.

On my iPhone I noticed that this feature had a constant purple arrow next to it indicating it was using my location; even more interestingly this wasn't showing in the upper status bar. While on this settings page I noticed there is an option to display when these system services are using your location, this was off by default. Upon enabling this I could clearly see when the system was using my location, which I monitored this for a while.

It soon became obvious the time zone detection feature was constantly using my location, so last night I disallowed time zone access to use my location and today I've managed to get 2hrs 17mins usage, 9hrs 20mins standby and I've 84% battery remaining.

I suggest that those with battery issues try the same experiment as myself, hopefully this is the solution we've all been looking for.

Regards,

Mike.

I was having big issues with 4s battery life, draining heavily even when it was on standby and noticing it was getting quite warm sometimes as well. Seem to have resolved this by going to settings>general>restrictions, and once you have set up a pass code turn off ping, now getting massivley improved battery life..

I was having the battery drain issue and heating phone as well until I did only one thing, I reset the network settings and now my phone is cool to the touch and battery life is on par with my old iphone4. I think a network setting is getting stuck or is misconfigured coming from the store. I bought mine at the sprint store btw. Right now I am at 94% with 43 min of use and 1 hour 32 min of standby. Before when I was at about 90% I was only at 15 min of usage time. This is much better. I have all email to push, notifications on, location services on. I don't like turning those off because then what is the point of having a phone that can do all that.

Hi All

I think I have sorted mine. I turned off the auto iCloud uploads/updates and my battery has dropped from 100% to 42% in the past 24 hours with moderate usage.

Stats from the phone are:

Usage 2 hours, 57 mins

Standby 1 day

Apple is still saying there are no solutions (on the phone with them now) and they'll give me a new phone.

One person said I have 14 days, another said 30.  I'm asking them for the location where the official policy is written.

They also said I can't return it to a store, I have to do it online.  Supposedly then they send me an email and I use the number in that email to call AT&T to get everything reverted back to my old iPhone 4.  This feels like its going to be a nightmare, has anyone done it yet?

Are any of you who are now reporting satisfactory battery life using calendars with OTA synching?

My iPhone 4S battery drops 1% for 10 minutes at standby. I restored the same backup on the 4 and only 4S just so fly - this is not normal. Only in airplane mode iPhone not drainig battery. My friend has the same iPhone (4S 32GB White) and in him there is no problem, the phone keeps almost the same as 4 - *** Apple?!

The question about restrictions is, if they are already OFF, what difference would having ping ON do?  Also, when I turn them ON and setup a pin, just to turn OFF ping, then when I turn them OFF again, PING goes back to ON even though overall restrictions are OFF

I was seeing terrible battery life as well.  My AT&T 4S went from a full charge to 56% by the end of the work day.  I had hardly used it -maybe turned it on and checked email and texts 5 times.  I have iCloud and Exchange accounts set to push.  Turning them to fetch didn't seem to help anything.  Turning off Time Zone monitoring didn't seem to help either.

However yesterday for the first time I noticed my battery wasn't draining like crazy. The only difference - my wifi was enabled but not connected to the access point at work. 

So does leaving wifi on fix the problem?  I don't know.  It was connected to my network at home before I got to work.  Maybe the wifi itself has nothing to do with it.

Perhaps the scheduler for iCloud backups was stuck running in the background and it was finally able to complete yesterday morning before I left for work.

For the second day in a row, I've done the same thing.  Let my phone charge while locked and with wifi on.  It's been at 98% for two hours now.

So try the following:

1) Just leave your wifi on

2) Allow iCloud to complete a full backup

Hope this helps.

What does the Traffic setting do? I was going to turn it off, but I'm not sure what it does.

This is not a problem of settings, or icloud, or GPS, or anything else. Two identical phones work completely differently, what many people here acknowledge. Let Apple be better to move, and either issue a patch IOS, or replace all defective pieces.

JonGoldman: There are procedures described in my posts above in this forum & couple of other guys who suggested the same as well. Search for my name & look at them to resolve your battery issue. You dont need to return. This worked for me. I have all the features turn ON too.

kopec:  Search & read my posts & the replies to mine above in this forum to resolve your battery issue & have all your features TURNED ON too.

I charge and discharge from 0% to 100% from abaut week - it is not that. As soon as put my sim card into the phone at once saw that battery was running too fast. After a week is not better.

I guess I could give the iCloud restore a try, but keep in mind I completely wiped the phone and was able to replicate the problem by just adding my 5 shared calendars.  Nothing else, no restores, no other configuration.

I'm probably going to setup a Genius bar appt next week.  Heck, I'll even let the guy login to my calendars with a Phone that supposedly has no issues.
