Q: iPhone 4s Battery Life?

My 4S battery is getting better and better.  I'm on my third complete drain/recharge and this helped the battery tremendously.  Three should do it, then I'll go to nightly charges.  Priming the battery has made all the difference.

I reset my Network Settings...  Getting better Battery Life.  After resetting you will only need to re-enter

your Wifi password.   Nothing else is effected when doing network reset.

After trying many of the fixes listed here and elswhere to tame the power beast within my phone, I've found a solution that works  - at least for me.

My problem seems to have been in the email fetch as well.  Here are the steps I went through, battery is great now.

1.  Under settings/Location Services - turn off relavant services you don't need running.  At bottom of same page under System Services turn off relavant services you don't need running.

2.  Settings/General/About/Diagnostics & Usage - make sure Don't Send is checked

3.  Settings/General/Bluetooth - off

4.  Settings/General/Mail,Contacts - Fetch new data = Off, Push Off, Manually - checked.  At bottom of page click Advanced, and make sure that is manual as well.

Battery is great now.  Hope this helps.

Agreed battery drain isn't linear. Buy taking an average over a specfic time period is accurate enough for these purposes. Besides if the thing will last for 200 hours in standby mode as marketed, I'm not going to waste 8.3 days waiting for it to die just to prove a point. Especially when that's outside the 14 days returns policy.

I got the iPhone 4s on Friday. On Monday night I let the phone drain all the way down until it shut itself off. I trickle charged it all night. Battery indicator only got to 97% - plugged in from 10:30PM to 6 AM. Tuesday night the battery was down to 13%. I again charged it from about 10:30 until 6:45 - again only 97%. Anyone else experience this? Is this a battery or software issue?

Sorry Barefootdoc. You didn't buy the iPhone 4S to turn features OFF did you ? Whats the point if you cant use a product for what its made for?? 

Folks please stop working on work arounds. There is a problem and we all need a fix ASAP.

I've tried all the suggestions in this forum and still have pretty crappy battery life. The only thing that actually worked was turning my phone off. I will try to call APPLE again this evening after work. Last night they just gave me suggestions similiar to those in this forum. I hope there's a fix before my 2 week return time ends.

It did it to me once with the 97%. The battery displayed a plug telling me it was charged and it said 97%. I ran the battery down below 10% and then charged it back up and ever since, it has been going to 100%.

I'm sort of curious about why the phone wants the GPS on for "cell network search."  I also can't think of any reason why "setting time zone" needs to be done by the phone's GPS when it's likely to be done automatically by the cell network provider (if the setting for using network time is selected).  I also don't see any benefit to _me_ by having the phone run the GPS to deliver "location-based iAds."  Those are easy.

I also reviewed location services by app.  Some, like navigation apps and restaurant-finder apps, obviously benefit, but there were a lot of apps that I can't imagine needing to know geographical location (book-type apps like Bible and Our Choice) and I turned all of those off.

Finally, I did turn on the status bar icon setting for the GPS.  Until I get more familiar with iOS5, I want to monitor when the GPS is being turned on because, based on my experience with fitness and navigation apps, having the GPS on makes a big difference in power consumption.

Two calls this morning and I'm down to 77%...all by 9:44am. This is after a complete drain of battery yesterday and full charge overnight and after turning off wifi and most location services.

Apple, we have a problem.  First osx Lion kills the MacBook Pro battery life (I *might* get 2.5 hours off on battery with minimal usage) and now the iPhone 4S (dead by the end of the day with consistent but very basic phone and email usage).

Apple, now is not the time to lose this one important competitive advantage Apple has almost always enjoyed.

As a mobile professional, I can no longer just grab my phone and Macbook and go anywhere for a few hours without also having to pack up both power cords.  Really very disappointing. Very.

Mine is doing the same thing too.  I'm at 75% after being off the charger for 2.5 hours.  At this rate, I won't even be able to make it through one work day.  Something needs to be done to fix this...quickly.

I have said this before and will say it again.  I cannot even get my phone to charge to 100%.  it only gets to 98% no matter how long I leave it plugged in.

Ok after 4 hours in its standby "door stop" state the battery is on 99%. So I think that the problem lies with the data connectivity of the phone. Which means that the general OS can't be running a random service sucking power in the background.

From my observations of what has been going on over the last few days, I believe the problem lies with the 3G connectivity of the phone. As you can't turn off 3G independently from GPRS, EDGE and WiFi, there is no way of nailing it down precisely. However I restored my iPhone 4 from an iCloud backup of the iPhone 4s this morning. I noticed a greater battery drain than I had before I upgraded to an iPhone 4s on the iPhone 4. It was loosing about 4-5% per hour. Which was worse than ever before with the iPhone 4. Almost on par with the iPhone 4s. All I did was disable 3G in the network settings and now it has been sat at 79% for the last hour and a half.

I think that if Apple released a fix bringing back the ability to turn off 3G independently from other data connections, it would fix the problem as a temporary measure. At least until they get to the root of the problem.

Just discovered that you can have mobile data switched off in network settings and still use the WiFi connection. I feel another test coming...
