My iPhone 4S keeps shutting down before battery is low

I made it a record 17 days with no problems but over the past 48 hours my phone has increasingly died at 18%, 23%, 29%. Same pattern as always. No apps running, using it for simple tasks, texting and phone calls, no warning, just dying. I only have my contacts, 1 email account, my music, and my facebook account. It started acting up 3 days after I added the facebook app. I deleted the app from the phone and it did not change anything, it still died at 29%.

This is my fourth iphone 4S. I have no other ideas. Apple does not help me when I go into their store. All they do is replace the phone.

Has anyone found any solution to this problem?

Exact same problem. Tried updating to iOS6.1.3 (Cheers, even worse battery drain that the last few updates) and a full restore. Keeps happening. Yesterday was at 48%, took me 5 minutes to restart. I have apps on there like a bus ticket, so this nis costing me money when it happens.

I did pop into an Apple store, but as the phone is 14 months old, they want me to pay to replace. Which is disgusting. I've already been hit with the power button issue (seen over 100 complaints about it on the net, yet Apple say not a HW problem) and lost everything during the update from iOS5 to iOS6 (whats the point in an ota update that requires a pc connection straight away?)

Any solutions? Due to the shoddy service and rip off pricing, I'll be leaving the iPhone after many years, but as I have 10 months on a contract, help would be nice.

My iPhone 4 (16 GB) has been somewhat better since I turned off the diagnostics logging.

However, it hasn't been perfect. So, I have no culprit to blame just yet.

My wife bought her iPhone 4 (identical model as mine) on the same day, same sales rep.

She lets the kids on it all the time.. no big deal to have a zillion apps running on hers.. she's never really experienced this problem. She does have to use the software version of the 'home' button - as her button seems worn out.

She is having problems with her latest update to the Facebook app.. but.. it's not shutting the phone down.

The other thing that I have done to my iPhone, recently, that seems to have had a positive effect .. is that I've deleted a ton of pictures off of it.

If the "Usage" screen can be believed, I currently have 1.6 GB available and 12.1 GB used.

I've been having a similar issue, since this past Sunday my battery indicator shows full 100% battery life but it never changes! I didn't notice it at first bu then my phone just shut off, when I tried to restart it, it gave me the "battery drained plug me in sign". I plugged it in and the same thing has been happening since.

Today I unplugged it (around 630am)after a night of recharging and here it is 2:11pm and it still shows 100%.

What gives!

This just started happening to me as of late. My iphone 4s keeps shutting off automatically. It has been shutting down at around 32% everytime. It shows me that the my battery is completely dead because it shows me the battery empty with the little red bar of battery left and the charge symbol.

When it does charge to 100%, i unplug it. Today, my phone stayed at 100% for a good amount of time, and then it drains battery so fast! Lately my phone battery has been draining supper fast.

I know restoring my phone could possibly help, but i'm not sure if it is worth the risk to lose all my data on my phone. Because what if it doesn't work? I've had my phone for a little more than a year.

I have the latest updates and everything. It also seems to charge back to full 100% pretty fast, but it may just be like that always

Mine was going off always at 5% and a few times randomly at around 20%...

As I had extended AppleCare, over the phone I was told to restore using the "recovery mode" procedure but that didnt help...

Apple then replaced the phone and all seems back to normal for the last 4 days - the battery goes all the way down to 1%...

The company did not respond about it until now?

She does not follow the issues of their own discussion forum?

My phone started to exhibit the same problem this week ...

I have an iPhone 4, with the latest iOS possible. It decided to join "the clup of random battery terror" 2 days ago. It turns off at %20, %30 etc. Actually, this is very interesting because it happens to the 3gs and varying iOS versions. I have 3 more friends with the same problem. Waiting for a serious solution.

Cute tip: Hold home+power for a couple of seconds to turn on your phone. It will let you do some short tasks, but then it dies again.

Sometimes I miss the older non-smart phones.

For what it's worth, as an update to my prior comments on this thread.. my iPhone 4 seems to be behaving better these days. I wish I could tell you the one thing that got better, but I don't have much of a clue.

I myself am a software developer, and, I know how rolling out an "update" to one of my applications is a mixed blessing.. my end-users like the new features, but, if I wasn't careful, I can easily "break" functionality that they relied on. Thus, my outlook on software updates is very cynical. So, I can tell you this much.. I NEVER UPDATE ANY OF MY APPS when I have a phone that works to my liking. The only app I really updated over time was my "Facebook" app. If there were others, I cannot recall.

Another funny thing.. my wife's worn out HOME button is starting to work again.. so.. we disabled the soft-HOME button (which was a glorious thing to get off the screen)

It is simply absurd for a company like Apple does not provide a definitive solution to this problem! I've tried everything, everything! And the machine will continue to reduce wasteful consumption of battery on and off at 35% battery indicated. And I can not believe that to "optimize" the battery life I have to disable a number of services or functions of the cell's most advanced twenty-first century.

My iPhone 4S was/is shutting down when unplugged, shutting down randomly at different percentages, just being a big pain. I'd lose a call with my deployed husband and have to start back up many times. Although I stream music at work most of the day, it wasn't an issue before...

Anyway, I called Verizon and the tech told me that using chargers that are not Apple could be an issue. But I didn't really count on that. And having Apple run a diagnostic just wasn't on the top of my list considering the drive, and the fact that most of you have had the diagnostic with no answers.

A forum on Verizon's site had a comment from a user about going into Settings>Safari>Clear History and wow! In the past 30 minutes I went from 20ish% to 46%! Not sure if many of you browse the net often on your phones, if you don't then maybe transfer photos to your computer and turn off alot of location services along with clearing the history. But at least give it a try, and let me know if it works!

I don't think it will work, because people got brand new phones and the problem consists. I think we are doing something in common that causes the iPhone to misbehave in terms of battery calibration.

Maybe the cause the plug we are using to charge the battery...I don't know. I really don't know. But I'm seriously thinking about getting an android phone. They are more customizable, iPhone is have a sturdy OS but little any problem is almost unsolvable. If it was android, we could use a battery calibration app and solve the problem....or we can try a friends battery etc

Hello all....I know this is an old post but I too had this very same problem and found a solution that works to what was causing the problem for me....

PROBLEM:

I remember when I first got the phone I charged it to 100% and then used it for the day but it only was at 38% by the end of the day..I would stick it back on the charger...it would charge to 100% and I would leave it charging till next morning....Then at work I would use it for a while and it would get down to 70% by lunch and I would stick it back on the charger to bring it back to 100%....I kept doing this for about 2 weeks and then noticed that when I would use it at home and watch netflix or something that drained the battery quickly it would die at 41%...I would charge it back up and it would come up at the same percentage that it died at....this kept happened but at random percentages...but it would never go down to 1%...I then started noticing that when it charges back to 100% it does not go to 99% or lower for at least an hour of heavy usage when usually it is supposed to start dropping only after 5 or 10 mins or less of usage...I did some research online too and read someones blog that the batteries have built in memory so whatever percentage you are at when you charge your phone back up, is where you phone thinks you are "out of battery"....and in turn will die out when you reach that percentage...Which also explains why it stays at 100% for an hour...the battery is probably looking at the 41% as 0% and therefore it stays at 100% for an hour because it was actually dropping percentage in the battery memory and by the time it dropped to 99% the actual percentage is 58% full....We see 99% full battery on the phone but the actual battery percentage is 58% full....So it dies at what we see as 41% but the actual battery percentage is 0%....

SOLUTION:

You need to let your phone charge all the way to 100% (do not use it at all during this time) and then once it gets to 100% unplug it right away and do not let it "overcharge". Then you must use your phone all the way down till it gets to 1% or even let it die off. Then recharge to full capacity and use till it gets to 1%. It took me a while because the battery was all whacked. I had to charge it to 100%, unplug right away, then let it die off...it would still dies at 41%, then 30% then at 17% and then lower to 8% and then eventually I got it down to 1%....Key is to not charge during the day when the phone still has battery power...wait till it gets down to 1%...

I have been successful doing it this way and now my phone does not die out till it gets to 1%.....except one night when I was ready to go to bed but my phone had 7% left on it...I did not want it to die on me because i use it as my alarm clock so I just charged it at the 7%....I used my phone the next day all the way and when it got to 7% it died on me....that was the first time that had happened in months since I started doing it the new way....I charged it back up fully used it again the next day and it dropped back down to 1% again....so I was glad it did not start acting up and proves the theory of the battery memory.....

Just make sure you do not keep charging your phone back to 100% until you have drained the battery to 1% or completely dead.....

I hope this post helps a lot of people out there...I know I would have been grateful to come across a post like this....GOOD LUCK ALL!!!
