Q: iPhone 4s Battery Life?

Same here:  I did alot of what people are saying here.  I just pulled my iphone off the charger at 1:00pm PST. and at 1:30pm it's at 92%.  It's holding it's charge a little better than it did yesterday and did charge to 100% not like this morning at 93% even when on the charger.  I hope this gets fixed soon.  I am on my phone all day long.  Using it for work and perform 4 to 5 online demo's for my work.  I can't keep plugging it in.  It's not only a hassel but it's eventually going to destroy our battery's.  Not acceptable. 

Thanks! To be safe, I also deleted my Gmail account and set up it again from scratch to top it all off

Update--I've been using it for over 2 hours now, playing music, games, checking email, downloaded a few apps basically the whole time...battery is down to 91%.

Not sure what worked, but this is drastically improved from yesterday for me!

Just to let you all know, I have just come off the phone from a guy called Jason from apple technical, he has been intouch to find out a solution to the problems that we are experiencing, so Apple do know there is a problem and they are trying to sort out the problem which is really nice to know.

we were on the phone chatting for at least an hour, great guy to chat to and knew his stuff, they have installed a logger on my phone to log all what I do, it will log how I use the phone and also log the battery condition and charging in the next 24 + hours, he will be calling me back to arrange the file to be sent to him.

Just thought I better keep you all informed.

2 hours 91%!  Really?

Also, don't know if this matters or if there's any relevance, but before I did a restore, apps kept crashing daily.  for example, I'll go into settings and check my usage data, but right before I am able to touch usage, it pops back to the main home screen.  I checked the diagnostics logs, and there were plenty of them for crashing, and a couple low memory issues.  But since restore, I have had zero issues, and phone seems to be running quicker.

For what it's worth, there is an interesting trend appearing in several threads concerning rapid battery drain with new phones running iOS 5 and other phones upgraded to iOS 5.

The culprit appears to be the facebook app. Try deleting it and see if the problem clears up. There are a number of people reporting that removing the facebook app has fixed the problem.

One person in particular detailed the steps he took to troubleshoot, including wiping the phone and setting it up fresh with no apps installed at all. Testing for a full day, battery life was "normal". After installing the facebook app, battery life began to plummet. Something about the way it polls for updates is causing a problem under iOS 5. I can't say I'm surprised. I'm no fan of facebook. I haven't had any problems myself since updating, but then, I killed my facebook account and deleted the app when they announced the last batch of changes, so it wasn't on my phone when I upgraded to iOS 5.

Try it.

I've got 1 hr of usage and i'm at 78%. Haven't been doing much except sending some emails and playing with settings and some txts.

While I was talking with an Apple rep, I lost 5% within a few mins of having the phone on. This can't be right, can it?

The rep told me to take the phone to a Genius for diagnostics.

Add me to list...

2nd iPhone 4S, Black 32gb AT&T

First was preordered & received day 1, swapped out for a new one a few days later.

Had an iPhone 3G & 4 prior, never had battery life this bad.  The iPhone 4 was running iOS 5GM as well right before I sold it, so I'm fairly confident it's not the entire iOS to blame but a combination of things. 

I've tried running the phone with a lot of things disabled, but went back to running it exactly as I had my iPhone 4 prior to the upgrade to the 4S to get a true comparison since I have the same apps and settings and didn't have this battery life issue with the 4.

• Tried restoring as new phone, resets, resetting network settings, you name it
• Deleting & re-adding back email addresses (2, an iCloud & an Exchange)
• Disabling miscellaneous notifications from 3rd party apps
• Turned off Ping, disabled location settings for iAds, diagnostics, time zone

• Have WiFi & Bluetooth on
• Tried using both WiFi sync to my iMac as well as iCloud
• Running Push on iCloud & Exchange.  Tried running Fetch every 15, didn't help really.  Back to running Push on iCloud but Fetch every 15 on Exchange

What's interesting is I found a couple odd things occuring.  One is when I do a hard reset that the phone loses track of the usage stats, they simply go to dashed lines. 

Another is in the Diagnostics, I have TONS of error messages!  I literally have to fling my finger as fast as possible to scroll down and it takes a few seconds to go through them all to get to the bottom.  Many are app crashes, memory crashes, and a ton of Bluetooth disconnects. 

I'd be happy to speak with someone and provide as much information as they'd like to get from me.  I'd be happy to send screenshots as well! 

Yeah--I'm at 2.5 hours now, down to 85%. However, I've been using it pretty constantly. Music going pretty much the whole time, and just spent a good 10 minutes with facebook open, checking weather.com, reading emails, etc.

That said, battery life is going down, but seems to be doing so at a pretty normal level (or the level I'd expect). Idling the phone now (no music running, locked screen) to see what it does, but like I said, battery performance seems to be drastically improved after the steps i took.

Got A New iPhone 4S

Went to the Apple Genieus Bar today after trying everything posted here plus a number of factory resets and chatting with Apple Support.  They hooked up my 4S to a laptop, the guy said thats not right, did a reset and noticed that my 3G kept on going offline, then back to search mode and locking in to the 3G signal only to go offline again. This is despite me getting 4 bars from AT&T in the store.

He left, came back with a new 4S, transferred my sim card to it. I resynced with the cloud got everything back, then restored from back up with my laptop.  This process took about 35 minutes in total, and in this time he saw my old 4S go from 85% to 77%!

The Results

Charged up my new 4S to 100% with everything on the way I normally had my 3GS. WIFI ON, BlueTooth ON SIRI ON, 3 email accounts with PUSH (NO EXCHANGE).  I am happy to report my Battery seems to be holding up far better.  It is not as good as my 3GS was, but it is nowhere near what my new 4S was doing.

So far;

Usage has been 48 minutes

Standby is 5 Hours 30 minutes

Battery sitting at 93%!

NOTE: My iPhone did get warm to the touch during charging and use, the new one does not.

This has got to be a problem with almost ALL 4S users. We're just the small fraction talking about it online. Half the people that own iPhones don't even notice or care or think the battery life they're getting is "bad."

I've noticed that for several days my battery consumption seemed normal, then today I began having issues with my 3G connection through AT&T (plenty of signal, but no connection, wheel just spins, can only make it work for short periods of time by cycling into airplane mode and then back again) which in turn led to serious battery issues along with some pretty heavy duty heating.  I've shut it down, restarted it, reset network settings, reset user settings, pretty much everything but a complete restore, and the problem persists.  I love my iPhones, I loved my 3G, I loved my 4, but whatever funk Apple is in right now is making me grumpy about my 4S.  We need a fix soon Apple.

I had the exact same issue since day 1 of receiving my new 4S, was so disappointed. I found a post on DFU mode restore, and that fixed the problem. Managed now 24hrs with a drop of 20% battery life from 100% to 80% (light to moderate usage) http://themacscreencastguy.com/blog/2011/10/17/iphone-4s-battery-issue.html

Usage: 40m

Standby: 50m

84%

All I did was browsed web on 3G for about 25 mins and played Where's My Water for 15.

I don't think it's to do with stuff running in the background because when it's on standby it holds charge really well. Like only drops 1% an hour or something. It's just that every time I actually use the phone it drops like mad, a percent every couple of minutes.

It's trivially easy to disprove your statement. My 4S does not have a battery life problem; my battery life is better than my 3GS. You don't realize how tiny a fraction you are. There have been 5 million 4S phones sold. A tinyfraction, like 1%, would be 50,000.
