Q: iPhone 4s Battery Life?

Thank you. The maximum that I've got was 5 hours and 30 minutes. That is the reason that I'm afraid with HW.

I really don't understand what is happening...

Suppose that was SW... - doing a reset and restore should work for all devices

Suppose that was HW ... - why do we have bad experiences with 4 and IOS 5?

Both I don't know

NFB, That looks pretty normal, and I wouldn't consider HW replacement.

Realistically, is it causing you a problem? If not, enjoy your phone.

Just hang in there until Apple do a update on the iOS to tweak it to get *even better* battery life. It's been mentioned previously that apart from Location Services / Communications to Apple / there are many *rogue* apps that can also cause drains. It would appear that there is a lot for Apple to consider here and they don't want to hastily come out with a fix that isn't going to work for the majority!

Enjoy your phone buddy.

Thank you so much stujj

• Usage: Amount of time iPhone has been awake and in use since the last full charge.  The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
• Standby: Amount of time iPhone has been powered on since its last full charge, including the time the phone has been asleep.

Wake up people. I don't have an Iphone but I know more about it than most of you.

• Talk time: Up to 8 hours on 3G, up to 14 hours on 2G (GSM)
• Standby time: Up to 200 hours
• Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi
• Video playback: Up to 10 hours
• Audio playback: Up to 40 hours

If you don't implement settings that they talk about in the first link, then the more chance you have that the 6 hours 3G will become contiguous i.e one after the other... and it does make sense because your apps and all use the internet. It's not rocket science.

Hi Justalii,

I bought 2 64Gb 4S's and one suffered and the other didn't. The faulty one would drop 16% in 8 hours, even with a full wipe and no sync/connection to iTunes (e.g. a completely fresh install) and no calls/texts and only in standby/sleep. The other has standby of 2+ days with 1.5 hours of usage with battery life still at 20 odd percent. (hardly used though). And that only dropped 2% overnight! I charged them both, put them side by side and in the morning, one was at 98% and the other 84% - same network/etc. Deffo a hardware issue.

Waiting for my replacement as we talk!

I have a same issue with battery as most of you!  Since i purchased iphone 4s i have 1 charger by the bed, 1 in a car and 1 at work , I really enjoy Apple products but I'm getting to the point where i just might drop the iphone 4s.  Im also experiancing problams with sound when making a call, everything sounds dead for about 15 seconds and then starts ringing, and no it's not the other persons phone or signal it thoes the same thing when calling fixed phone and i never use bluetooth or headphones, and 1 more small issue.....when I open SETTINGS most of the times it just takes me back to home screen, and then i have to open it again so i can finish what i started!

Yeah, there's something really weird going on with these phones. Me and my friend bought one each at the same time. Mine suffered terribly, but his standby was ok (although he complained that battery drained too fast while it was in use).

Standy on the replacement is fine, but sadly it has a rattling power button

I've never been so frustrated with Apple before! In a short time I've moved from their biggest fan to a very unhappy customer. First Im one of the lucky folks to get hit hard by the 4s battery life problems. I tried all the possible solutions offered by the community base out there but nothing helped. Of course instead of take immediate responsibility Apple stays silent until recently and can only promise a fix in weeks. How did it even get through testing to begin with? But I was patient and called support. First they offer to open up and attempt to repair my very new and very expensive phone. I pushed back nicely and finally got them to agree to a replacement. I expressed concern that I would be without a phone for a long time. The rep said it would only take '2 days'. Two days to ship a phone to their facility, process it, and ship it back sounded incredibly unrealistic. But I didn't say anything. I was going to Mexico for vacation and figured it would be home by the time I got back so I didn't say anything. So I shipped it off and checked FedEx to verify they received it. But after a few days I got no info that a new phone would be shipped to me. Then I checked my credit card account and saw that I got a $200 refund from Apple. What?! Refund?! $200?! I asked for a replacement and not a refund. And that phone cost alot more than $200. There is no email support for the iPhone I could find, so I had to make a call from Mexico. A $70 call after all the waiting on the phone. When I got through to a person (the voice recognition couldn't understand a word I was saying) I gave the Rep my replacement case number. The Rep said he couldn't access the case number, didn't know what happened to my phone, didnt know why I got a partial refund, and had no other information. He could only recommend that I call back to a supervisor who would have more information. Of course I can't afford another $100 phone call. I've had it. After I straighten this out when i get home and I'm going to consider other options. Why is it that all US companies grow too big and forget how to provide reasonable customer service?

You guys are a bit simple sometimes. I think I'll go watch a movie.

You see, the battery meter and usage time is really not relevant and I can't understand why you place so much trust in that. If you take a device from a full charge at 100% (and you went through 2 charge cycles+ since you've had the device) then you use it for 6 hours straight on 3G internet, then you've proved it's on par with Apple's claim in terms of usage. It makes no difference if one device drops 10% in 5 minutes and the other 1% in an hour. So that's one thing.

The other thing is that if you always put your device in airplane mode when you don't use it, and it doesn't drop in any significant manner during standby, then that most likely proves that there is no hardware issue. Because a faulty battery would not need 3G to be faulty.

Now, if it drains during standby with 3G on but in a huge way, it may be setting/config related or malformed data related - error in the polling of a mail app, or just too much polling from all your apps etc. But don't forget auto-checking emails and apps updating their data through 3G COUNT as usage, even when you're not touching the device. Having no mail no app all network centric settings to off will allow you to test that. It may be where the phone is, there's bad 3G coverage and that drains the battery... like people have had big drains going through airports or in some spots in the UK. Apple says it that bad coverage will create a drain.

It's that sort of reasoning that will go a long way, not relying on monitors that may not show things in a "linear" way because of error conditions... projections or extrapolations of usage time/battery introduce uncertainty. What has to be tested is full recharge in airplane mode or off, then use until 0%/shutoff, nothing short of that.

Good luck!

Was it really on 95% when you took it off the charger? I had similar "OMG how did it drop to 92% already?" thoughts, but then I realised that sometimes it wasn't being fully charged in the first place and after a night of charging, I was taking off the charger at just 92%...

That (weird) problem was solved by moving from my old iPhone 3G charger to the one that was supplied with the 4S.

for all you Apple support engineers monitoring this forum, here's my (not massively scientific) observation:

standby time - fine. internet browsing - OK

Battery drain really kicks in when the connectivity blocks power up.

e.g. 1 hour GPS turn by turn navigation (spoken voice) = 20% battery capacity

e.g. 1 hour phone call (good reception) with bluetooth headset = 10% battery capacity

these high drain activities might also have somehting to do with the fact that the screen is on all the time.

After I fully discharged my 4S a few times, battery life has been nothing short of amazing.

Now Now you plugged it in on a top off. BUT I do charge every 3 days. Use on average 22% daily.

Sadly,

After reviewing post after post of suggestions...I'm compelled to point that the reason we all purchased this phone was to utilize ALL the features without hesitation.  There should be no need to attempt to guess at fixes or make complicated remedies for the technologically savvy.  The answer may very well be to just return the **** phone.  Such a disappointment for my first non-ipod Apple product! 

How many times? I have achieved 9hours :)

You do have Phone service and SMS, I turn it off a lot, just thought I would pass the info on :-)
