Q: iPhone 4s Battery Life?

I had that issue as well, I got up at 08:15 and my battery was dead by 1:30 that afternoon.  I had been to the genius bar twice, once they reloaded the phone, the second time they gave me a new one. They really are very easy to deal with, unfortunately, the problem still persisted.  I noticed that the phone kept updating mail and nothing ever updated. I deleted my icloud account and I have been using my pnone since 07:30 this morning and it is now 9:24 pm and I have made face time calls, sent and received text and mail and had a few phone calls and my battery life is at 75%. 

 

Check the mail and especially the iCloud account.  When you resync the phone make sure the iCloud account does not come back on.  I hope it works for you...I don't use iCloud so it is no loss to me.

I am happy that you have resolved your problem. 

Again, users who RESTORE their phone from another phone's backup seem to have a problem.  Just do the reset, and they SYNC your data back onto the phone.

It sounds like a program didn't terminate properly, and ended up looping.  You might try deleting that app, and downloading it again.

I'm not speaking about daemons, or REAL background processes, that are hidden from us in normal use. I spoke about apps running in the background and can be viewed in the iOS taskmanager (double press home button). 

that really helped me as well,

i can see a really bid difference since i deleted icloud account.

i will back up my contacts using gmail, i don't need icloud anyway.

thank you so much

Gooner90, reset your network settings, settings>general>reset.  Please note that will drop any wifi connections you have and you will have to re add them but may correct your issue. If not, then go to same tab and choose the  "Reset All Settings" option. Setup as new phone when it reboots. This will not erase your data. Once you go through the wizard the phone should be back like it was other than the settings will need to be configured how you want them.

Did you update from 9A405 to 9A406?

 

If so, did you restore from backup after updation or setup the phone as New? And did you notice any significant improvements?

 

I ask this because I am on 9A405 and for a large amount of time, my battery life was excellent, however it has been trash since the past 10 days. Also, my phone gets hot whenever I access 3G data or prolonged data usage.

Is it advisable to update to 9A406?

One thing you may want to consider it leaving your iCloud acct but only turn on "Find my Phone". That could come in handy sometime if you misplace your device or is its stolen. That seems to run fine. Of course if you turn that on and notice battery problems again then turn back off.

Hi im still on 9A405 and im getting a day and half out of my battery with most things turned on so im not updating till apple brings the new new update out LOL

thanks mate,

Really a huge difference, every now and then batterie dropps 1 to 2% (average 5% an hour using my phone for at least 20 minutes in an hour)

working on it, mails and appstore downloading

one thing i also did before deleteing my icloud account is to set my mails (3 in total) to fetch instead of push.

and also date and time to manual instead of automatic, i read about these somewhere on this thread, but what really made the difference (i think) is the icloud deletion account.

thank you all for this helpfull thread

I just updated recently -- still investigate how long will it stay but it looks better so far with 9A406 than with 9A405. My last status with 9A405 was 24 hours standby + 12 hours usage and 42% battery available. This is with moderate usage of phone, Apps, Mail and Internet. GPS disabled. (I don't really see a reason why I should be tracked all the time)

But, to achieve this I had to disable few things as advised by Apple: http://www.apple.com/batteries/iphone.html

According to all sources Apple originally released the iOS 5.0.1 (9A405), then shortly afterwards re-released iOS 5.0.1 (9A406) in order to address the promised battery fixes, that were apparently omitted from the 9A405 build.

It is apparently advisable to upgrade to 9A406 -- this is what iTunes will load today to your iPhone 4S if you select to restore your phone.

In my opinion the battery troubles are primarily because of improper management - you stop using certain feature (such as 3G) or application, but they are not immediately disabled and continue to drain your battery. I believe this is what is actually fixed in 9A406. The new iOS version 5.1 might bring other improvements.

I will keep you posted with more details.

I drained my battery yesterday and this is what my Stats were

Usage: 6 Hours, 30 Minutes

Standby: 1 Day, 4 Hours

Is this any good or not??

Thanks

9A406 was actually released to address sim card issues with reporting of no service or no sim card. Nothing to do with battery supposedly but it appears some users have seemed to get better battery results after installing  it. Maybe because of sim issues draining battery? Who knows. But certainly it shouldn't hurt to install it.

BTW that is steller battery results you are reporting depending on the type of usage.Trying to calculate it against specs but not quite adding up.  And you are dead on with the advised optimization. That seems to be key to increasing battery life per charge.

28/200= 14% std by   6.5/7.5= 87% usage  so 100%- (14+87) = 101% so you are above spec. Of course that is based on average 3g/wifi on the usage. Apparently you had a little different type of usage (maybe music or phone and less internet) so that would change things. Anyway it looks like you are getting the usage you should be at first glance.

Thanks a lot sbailey4 and dkalchev.

I will update my phone to 9A406 over the weekend and report any improvements.

Although dkalchev, did you "Restore from backup" after updating to 9A406 or "Set up as new phone"?

I hope to get even better result, but am sort of constrained by the requirement to keep up an VoIP session at all times (to get calls from another phone number) -- there must be an always-on Internet connection via either WiFi or 3G. My better results were with keeping WiFi Off and relying on 3G for the VoIP connection, but had switched it on for faster browsing/email.

I aim at getting consistently good battery run time, as it is not OK to have your phone without charge. Let's see if 9A406 will turn to be better -- at least in not forcing me to babysit the iPhone.

One thing worth noting is that when your iPhone 4S is charging and displays 100% it has not finished charging. You are better off leaving it connected to the charger for some more time. I believe the iPhone is actually reporting 100% when the battery reaches some 'safe' level, like 90% --- thus reducing the risk to damage the battery cells if you charge it in cold environment and then suddenly the battery gets much warmer (with full charge) -- this condition is very damaging to lithium-ion batteries.

So it is sort of tradeoff in not having fully charged battery (it starts quicker showing < 100% charge) vs. having it last more charging cycles.

Gooner90: I chose to restore as new. This is because when I purchased the phone, the operator activated it on their iTunes workstation and I didn't feel good about this -- so used this occasion to make it 'brand new'.

But, you may wish to backup and restore the phone anyway, or at least backup your data carefully before the update. I am missing some videos I made on the iPhone that didn't make it to Photo Stream..

PS: It's early to tell, but it seems with 9A406 my iPhone 4S is discharging at less than 1% when idle (connected to WiFi and with the Bria VoIP application running in background).
