Q: iPhone 4s Battery Life?

Here is what you should do:

1)Backup your data to icloud and connect the iphone to itunes

2)Restore your phone

3)Reconfigure your phone( DO not use itunes)

4)Retore all data using icloud

I have done this and my phone battery life has gone better from 1% every 15 min to 1% every 45 minutes

Hope this helps

I had noticed my iphone 4 battery life was being seriously effected.  I tried all sorts of things, but think I have found an answer.  Under settings general click about  at the bottom is a section called diagnostics and usage it was set to automatically send.  I set it to don't send and my battery usage seems to have corrected itself.

hmm....then i guess i can be of no help to you... I don't know what else can be done to solve it.

Guys, i would like to share something else. Before when i had bad battery life and not making it through the day, i jailbroke my iphone4s once, and there was a tweak called " iOS 5.0.1 Battery Fix " in Cydia, which does helps in preventing battery drain. But i didn't want a jailbroken device so i restored it with itunes

My comment was for those who repeatedly exchange their iPhone 4S hoping for 'a better sample'.

IF your Usage and Standby times are very close, then by all means you do not have problems with hardware, but you have problems with software. The "Usage" time is accounted for, when some task in the phone requests runtime form the OS.

IF iOS is broken and it doesn't know what happens, you will have your batery drained and no indication of any Usage.

You need to find out what that particular thing is, then either disable it (remove it from your phone if it's an third party application), configure it properly so that it doesn't run at all time on your phone, or just learn to live with it.

IF on the other hand, you have almost no Usage time, and for short Standby time your battery is discharging, then you either

- have brand new phone that you need to recharge few times and then judge all this;

- you have an defective battery that needs to be replaced.

Another dissappointing moment for me. After installing new firmware from itunes and I didnt install a single thing. Everything is off. 1 hour later. 29 minutes of usage. I don't get it. I'll never do... Will report back again in the morning. I don't even wanna look at the phone neither touch it anymore.

 

Have you done full software reset? Or at least network reset?

You may try disabling Location Services (or at least System Services in there as these are of no use to you anyway). At least, enable the location services usage indicator and see if it is on while your phone 'does nothing'. (Set it in Settings -> Location Services -> System Services - Status Bar Icon)

These things are on by default on iPhone 4S and will drain the battery as some of these features use the GPS at all time.

Alternatively, you may have poor quality 3G signal. Unfortunately, before iOS 5.1 we cannot switch 3G off, so this kind of battery eater is more difficult to diagnose.

Well my phone has been restored in DFU mode guys. Before doing it I put in a new micro-sim from Vodafone as well. After the restore I didn't install a single thing. The phone is literally naked. Nothing no app no internet. And I have half usage time of the standby time. This is inexplicable guys sorry. I've tried all things like reset network settings and reset all settings too.

I got my 4s last year November. It was working perfectly fine up until 3 weeks ago. And this problem just not going away...

My phone was showing similar tendancies in that it worked perfectly well then started misbehaving, unplug phone from charger at 7am, few phone calls check a few apps, maybe email, read some news, 10pm go to bed, phone shows 70 to 80%, get up in the morning, phone dead, have to put on charge and re power up, takes an age to unlock sim, several tries, same thing happens the next night, the phone lays on its back overnight, now here's the thing, for the past couple of nights i have stood my phone verticaly overnight, wake to find there is still over 50% in the morning, and there is still 26% this evening. What the **** is going on? The phone in the first place shouldn't use any power when it is just idle, but the fact it uses less during the day than at night is weird. I have followed all the other advice about switching stuff off and frankly makes minimal difference and shouldn't have to be done quite frankly, bit like pulling 2 spark plug leads of the car to get the fuel consumption as stated by the manufacturer, maybe APPLE should state the stated battery life will only be achieved with the phone turned off left in a vertical position with your hand in the air

It seems to be a fact that you're ignoring some fo what we're staying, as well.

 

It's also a fact that my brand new iPhone held a charge for four days while it's Usage and Standby numbers were similar to what Julymel displays above (i.e., minutes of Usage time compared to hours of Standby time, an accurate reprsentation of how much I'd used the phone), but that after the Usage and Standby times were in lock-step, the battery started to drain in 24 hours.

 

Come on. I had my first phone for six weeks. It hard gone through MANY more than ten charges, and actually worked fine when I first got it.

 

We're (at least some of us) not talking about battery life that's somewhat below rated usage. We're talking about batteery life that is 10-20% of what was advertised. That doesn't get better, no matter how many times we've charged  the phone.

I certainly understand.  It seems about half the people who are here have this kind of problem.  Basically, it is telling you that something is running that is using the processor all the time, which is going to cause unreasonable battery drain.  Some of the cause seems to be a SIM problem, and other causes are a bad app, or a data corruption issue.  Fixing it may be as simple as resetting all settings and data, and then rebuilding your setup without restoring from iTunes, or restoring as new, then syncing one thing (apps, contacts, ringtones, etc.) at a time until you find what is causing the problem.

Another method would be to find a friend who doesn't have this issue, and compare settings and processes.

I'm currently using my iphone 3g and was going to buy an iphone 4s tomorrow......then i found this post :s

 

Is this ios update likely to make the battery much better? Or do you think i should stay away from the 4s and wait for the iphone 5 to come out later this year?

One can get a really false impression from reading the messages here.  The vast majority of users of the 4S have no battery issues.  Just make sure a NEW microSIM goes into your phone, and DON'T restore from the old iTunes backup, but rather set it up as new, and then SYNC the apps, contacts, etc.  Check your USAGE and see that it is not incrementing along with standby.  If it is, then reset settings and data, and then rebuild your apps by downloading them from the AppStore.  I wouldn't use anything from the iCloud as this is rather slow, compared with USB from iTunes.

To test this, I turned this function back on (it was off), and let the phone run the rest of the day.  It took the battery down about 10% from noon to 8PM.  It's not off again.  Apple needs to fix this if they want ANYONE to send them this diagnostic data.

Did you install any apps about that time?   If so, get one of the apps that display the processes that are running (Battery Doctor that was discussed here recently does this), and check to see if something is running that is on your apps list.  Generally, the processes list is made up of the things that the phone needs to have running all the time, plus whatever apps you selected to run.

If you find something that is on your apps list that shouldn't be running, delete this app, and do a reset, then see if that helps.

I'm sorry, but I have waited long enough now. I got my iPhone 4S in October, and now as I write March 7th there has been no word from Apple about when these battery problems with be taken care of.

I have decided to sell my iPhone 4S and buy something else. Maybe a Nokia Lumia 800 which had similar problems, but was released long after the 4S and already has a fix coming out shortly.

If Apple would only admit that the problems exist and let us know they are working ona fix....

Smartphones have evolved. Nowadays we can see 1.5 Ghz Quad Core processors. RAM as high as 1GB. Different types of display Screens by different manufacturers like IPS retina display, Super AMOLED Plus, Super LCD, etc. But where is the evolution in Battery Life ?????

I am really unhappy regarding this. There is still the old 1400-1600mAh batteries used in almost 95% of all the smartphones. There are some 1700-1800mAh batteries being used by manufacturers like HTC but still not good enough battery life.

Now look at Motorola DROID RAZR MAXX, the device has 4.3 inches display screen, weighs 145g, with a thickness of just ' 9mm '. Yet motorola managed to put 3300mAh battery in it. Our iphone's thickness is 9.3mm.

if motorola can do it, why dont apple do it. I mean, I wouldn't mind if my iphone4s was 10.3 mm thick and had 1800mAh battery. When someone spends that much money to buy a powerful smartphone, he doesn't really cares if his phone is 9mm thick or 10mm thick. No one cares i bet. Afterall how much slim the phone has to be ? why sacrifice battery life just for the title of "World's slimmest phone" ??. Nobody gives that much importance to the thickness of the phone, afterall today's smartphones are all thin enough ( those days of thick nokia n95 are long gone).

I would really love to see an iphone with 4.3 inch screen and 3000mAh battery or more ( Displays of size 4.3 inch or more makes the phone big enough to put large batteries like 3300mAh). These days 3.5 inch feels small compared to android phones. Even those stupid sony ericsson phones have 3.7 and 4.2 inch displays.

Its possible to put 3300mah batteries in today's large screen phones. Manufacturers like HTC, SONY, SAMSUNG just dont try hard enough or simply wouldn't care to do it.

Hope iphone 5 comes out with bigger screen and bigger battery.

Are you not on the same planet?   There will be a large APPLE event held today, where a number of announcements will be made; One of which will be the release of iOS5.1 in the next week or so.

I've been struggling with iPhone 4S battery issues for a long time. But I have solved mine, and I just wanted to add my tip.

Up until now, my standby and usage figures have not added up. After heavily tweaking my 4S the usage time would still increase, even when the phone is inactive with the screen off.

I erased all data and settings and set the phone up from scratch. The oddness here is that I had to actually do this twice before the usage stats started making sense.

Other tweaks still apply, such as disabling the timezone sync etc but since I did the two complete resets on my phone it has exhibited really good battery life. It's as though something was in constant use and draining the battery even when sleeping.

Prior to this my 4S was setup with a restore from my old 3GS. Something to do with this must cause issues somehow.

Anyway, good luck!
