Q: iPhone 4s Battery Life?

Yep, beginning to see acceptable battery life now a week after my replacement 4S. Took it home and immideately restored it to 9A406, set up as new phone etc. Push/notifications/diagnostics all off , using Siri but not raise to speak, location off when not in use. It is CRUCIAL that people do a DFU Restore, google it if you don't know how to do it. Just as a comparison , my iPhone4 goes 3 days on standby, light use on 5.01 now, 9A406 not available for IP4 though.

Turn your bluetooth and auto clock off mate that should improve your battery 

This is my second Iphone 4s -- I returned my first one a couple of weeks ago. This one without wifi on when standingby, could go 3 days standby and about 6 hours usage. With wifi on all the time, it can standby 2 days and about 5 hours usage. After reading many posts here, I think this result is not too bad. However, whenever I use it, the battery drops 1% every 3-5 minutes. Just want to ask if this is common to most of you? If not, I am gonna go to return it again. Thanks and happy new year!

@alohabj73 I have the same issue. It drops A couple % every few minutes

I see rapid drop too, but only when cellular data is on. I guess it has to do with the static noise issue, because the noise is much worse when cellular data is on. I can still hear it when I use wifi only, but the noise is much worse with cellular data on. This is not noise I hear when using the phone for voice, but noise from the phone when I put the back(around the apple logo) of the phone to my ear and listen to the noise from the inside of the phone.

It looks pretty bad when one compares this with iPhone 4. iPhone 4S was supposed to be better than iPhone 4. One can imagine how the battery life will be for iPhone 5!

iPhone 4 -> ~3-4 days

iPhone 4s -> ~1.5-2 days

iPhone 5 -> 0.7 day???

However, whenever I use it, the battery drops 1% every 3-5 minutes. Just want to ask if this is common to most of you?

If I use 3G Cellular Data when browsing (5 bars coverage) I get 1% drop per minute!

How do you use it when you get 1% frop for every 3-5 minutes?

Ok so I'm a first time user of the iPhone. I've gotten myself a factory unlocked iPhone 4S 32 GB model. I've had the phone for around a week and like everyone else, I've been experiencing terrible battery life.

Being a first time user of iPhone (and coming from the Samsung Galaxy SII no less) I am very impressed with the phone. It is much better than any other smartphone I have ever used. The only problem? The battery life is just abhorrent!

Now I've tried everything mentioned in these forums from resetting settings to restoring the phone from the 9A406 build of iOS 5.0.1 to going through the charge and recharge cycles. However nothing seems to work.

There are a few things that I've noticed:

1. The battery drains alarmingly fast when cellular data is turned on. There is no option to specify whether you want to use only 2G networks (GPRS, EDGE etc) or 3G networks unlike Android.
2. The battery drain is much less noticeable when Wifi is used in place of cellular data. With cellular data the drain is around 7-10% an hour while with Wifi it drops to 2-4% per hour. Still not rosy but better than 7-10% an hour definitely. This is with push email enabled AND disabled. It seems to make no difference whatsoever.

I've turned off everything, including location services, diagnostics and usage and iCloud. However, push email is on and working fine on Wifi. My theory is that if a "smartphone" can't even give push notifications then it isn't very smart now is it?

When I turn off everything, including Wifi and cellular data, my phone easily lasts around 2 days. But then it just feels like a very expensive music player with phone capabilities.

I don't know if this is a hardware issue or not but my friend's iPhone 4 with iOS 5.0 lasts him 3.5 days with regular Wifi usage easily (he doesn't use cellular data much). I hope an update fixes this issue because if not I'll return this phone for a full refund.

After reviewing the posts yesterday, here's what I did and it fully restored the battery life to what it was when I first got the phone.  After charging to 100% I was at 91% after 5 hrs 30 min of standby and 40 min of use.

 

1 - I deleted most of my apps (the ones I added most recently around the time my battery started having issues)

2 - I "reset" in the Settings/General

3 - I let the phone battery cycle to zero

4 - I recharged to 100%

5 - I "reset"again

6 - I deleted my email accounts/rebooted

7 - Added email accounts back

 

Not sure which one of these steps fixed the problem but I figured it was either one of my apps or a corrupt contact after reading through the various posts.  Good luck.

I hate to say it but this most likely these will not fix the battery drain problem for long term. In maximum a week the battery drain will be back!

iPhone 4S has plenty of software bugs BUT it has also hardware issues (related to 3G). It looks like the software bugs in iOS 5 and apps are masking pretty well the hardware issues and lead the people to believe that there are no hardware issues (especially if one does not use 3G/Cellular-Data or keeps 3G/Cellular-Data off most of the time). Also if the iPhone 4s is loosing ~10% or more per hour in standby it is most likely that there is an app running background which should be killed.

If one is not happy with battery life of iPhone 4s then one should return the iPhone! Playing with resetting/reloading it helps for 2-3 days BUT it does not help on long term (>7days)!!!

You're right about cellular data on ios5 - it's like the 'dementor of batteries' !! I try not to have WiFi/3G on at the same time , also all Mail set to Fetch15mins. Had my 4S a week and beginning to see great improvements. Did you do a DFU restore & new phone setup ?

Yes,  I agree. The battery life of iPhone 4S is miserable in my opinion. I am curious how the battery life of iPhone 4S compares to the your Samsung Galaxy s2? Is it more or less the same? I am asking because I thinking to switch to Samsung Galaxy S2 from iPhone 4s.

Indeed nothing works for long term (except keeping Wifi and Cellular Data off all the time)!

 

1. The battery drains alarmingly fast when cellular data is turned on. There is no option to specify whether you want to use only 2G networks (GPRS, EDGE etc) or 3G networks unlike Android.

Indeed the 3G toggle has been removed in iOS 5.X.X even that existed in iOS 4.X.X. Also considering that iPhone 4S has issues with 3G and Cellular Data makes the missing 3G toggle even worse! It is not even clear if it is possible have a 3G software toggle in iPhone 4S because it looks like the 3G chipset MDM6610 (which can be find only in iPhone 4S) does not allow it because it is on "auto-pilot mode"!!!

he battery drain is much less noticeable when Wifi is used in place of cellular data. With cellular data the drain is around 7-10% an hour while with Wifi it drops to 2-4% per hour.

This is true and it has been described many times and many pages before here. There is a hardware issue in iPhone 4S.

 

I've turned off everything, including location services, diagnostics and usage and iCloud. However, push email is on and working fine on Wifi. My theory is that if a "smartphone" can't even give push notifications then it isn't very smart now is it?

I agree fully with you. For such an expensive phone like iPhone 4S it is unacceptable to use it as an dumb phone (i.e. keep off WIFI and Cellular Data off all the time and keep the email fetching on manual)!

 

When I turn off everything, including Wifi and cellular data, my phone easily lasts around 2 days. But then it just feels like a very expensive music player with phone capabilities.

I agree fully with you! It looks to me like iPhone 4S is a very expensive music player with dumb phone capabilities! The 2 days life which you mention is quite a in the range of  battery life what people are complaining here (with a lot of settings off).

I understand that the 200 hours standby from the specifications of iPhone 4S are when one keeps the iPhone 4S in Airplane mode in standby!!!! Airplane mode means that no phone calls can be received!!! I find it horribly wrong that one measures the battery life for a phone when the phone is kept in "Airplane mode".

 

I don't know if this is a hardware issue or not but my friend's iPhone 4 with iOS 5.0 lasts him 3.5 days with regular Wifi usage easily (he doesn't use cellular data much). I hope an update fixes this issue because if not I'll return this phone for a full refund.

Almost 3 months have passed and there are no iOS beta/updates in sight which looks like to be able to improve even a little the battery life. Because so much time has passed it looks like this is a hardware issue which cannot be fixed with software updates!

I experienced the same batterylife problems after I added four other mail accounts.

As soon as I removed the extra e-mail accounts I added, the batterylife went back to being ok.

Before I removed them I tried to change them to manual (from Push) but that did not seem to help.

Maybe multiple mail accounts causes some of the batterylife problem?

again , all this tricks , of switching off  some fetures  and restore settings  can't help alot as long ITS  hardware issue  !

what you think? will Apple finally admit that the new chipset is faulty ?

,  , I assume that the next batch of devices will already will have a revised chipset  that will solve the problem. and the main question is what Apple is going to do? unlike the antena gate of the 4 , rubber case won't solve the problem , Apple will have to recall ALL the faulty devices, or at least offer extended warranty ...

It looks to me that Apple just does not want admit the hardware issue (and implicitly admit that iPhone 4s is such an epic failure)  even that most likely they are working on manufacturing new batches of iPhone 4S which do not have the hardware issues and will change them quietly in the near future for those who bother to complain and come to the store. Luckly for Apple, for now iOS 5.X.X and Apps have plenty of bugs and Apple can keep for now the hardware issues out of disscusion and public's eye. I really hope that Apple is working on fixing this mess because right now it looks like nothing is happening.
