My iPhone 4S keeps shutting down before battery is low

I have this same problem with random shutdowns. I've had my iPhone 4s for a little over a year, am not a heavy user, rarely use apps, and have Verizon. No problems until starting 2 weeks ago. Shuts down when in use and also when not in use. Shown battery life seems to not always correlate with actual. Goes from 49% to 3% overnight when not in use for 8 hours. After the first shut down I assumed I'd drained the battery. I charged my phone overnight and when I turned it on in the morning it said battery was at 7%! I charged it a little longer and it registered 100%. After reading this thread I am still at a loss as to the cause.

Hi all - I have experienced the same problems - Iphone4 keeps trying to shut down about every thirty seconds (phone lights up and slide to turn off appears)- cutting me off mid call and generally making the phone impossible to use. I just removed ICloud and Dropbox, all the apps and all music and the phone now works perfectly again. Glitches in their pointless (ICloud and Dropbox) software I expect. Been fine for 20 mins now - I will slowly add what I removed to try to root out the culprit.

I have also been having a similar problem my iphone4 can charge for hours and the percentage doesn't move from 5% its also constantly turning its self on and off some times it kinda fades out I did a restore and it fixed it for a few days and now its doing it all over again I have had a new battery put in it and everything its driving me insane

I did restore twice. Did nothing except lose all of my preferances. While recharging my phone also constantly turns itself off and on and does not show battery charge level while charging. After the latest iOS upgrade battery charge showed accurately for one cycle, then back to unchanging. To know my real charge level I have to turn phone completely off then on again. I've only had this phone 1 1/2 years!

I've been having the same issue for several months as well. The phone will cut off when the battery is at a high percentage (this morning it cut off at 92%). When I press and hold the power button the dead battery symbol comes on the screen. When I plug the phone in the battery symbold indicates the battery is still at the high percentage. I've been to the Verizon store several times and they always say they don't know what's causing the problem. They had me reset the phone; when that didn't work they sent me a replacement phone. The second phone started having the same problems. They had me update to ios 7 and update all the apps, and of course it didn't solve the problem. They're sending me phone #3 now. I asked if it could be an issue with the SIM card since that was transferred from the first or second phone and was told no. They're trying to get me to pay for insurance to extend the warrenty. If anyone figures out what the problem is please let us all know!

I tried draining battery to shut down and recharging to 100% and it did not help 😟 I have done reset twice and restore (lost eveything by doing so) once without success. Phone still doesn't show battery usage correctly or charge % while charging, continues turning itself off and on while charging.

i am having same problem lately with my Iphone 5 and IOS7. I see my phone gets very hot when using the camera or the gps apps. but even when I turn the camera off as well as GPS, the drainage is growing and when it gets to 24% it shuts down !!!! dead, I connected to the usb cable and it started but showed 0%.... very frustrating indeed !!!! would I be experiencing same issues with the new 5S I ordered already ??

is there something wrong with the camera ??

Hi Rosie, I had the same problem with my iPhone 5. Was about to go to the Apple store when I realised that it wasn't charging properly as there was pocket lint in the socket on the phone, thus perventing the plug to be plugged properly. Once cleaned the problem disappeared completely. Hope this helps.

Good morning - I just replaced my Iphone 5 with a new or refurbished device - I noticed in the "old" one the e-mailapp - native iphone mail app connected to both Gmail and my exchange server - set on PUSH - was constantlychecking for new mail - you could actually see the line in the bottom of screen jumping like crazy - trying to check for a new mail constantly - so could this have been the result of the drainage and the over heating ??!!!

Thanks,

Hanani

I had this exact problem with my iPhone 4S. I read on here that the iPhone thinks that there is more power left in the battery than there actually is. A reset of the iPhone (hold power and home until apple appears) seemed to correct this and the iPhone went all the way down to 1% before it shut off. This simple operation made the iPhone work properly again.

I just talked to a service guy asked about the PUSH option - he told me Apple recomand to set up to PULL with 15 minutes intervals - and told me even if I get an email in between - it wil lsurface eventhough it is set to PULL. not sure it is true - checking....

leave your phone charged over night and when you wake up the battery should be normal. it worked for me and i didn't have problems the next morning.

On Nov. 17 my phone with the incorrect battery charge issues showed an iOS update was available that "resolved issues." So I updated. Part way through the update I got the image showing I should connect the phone to iTunes. Once connected to iTunes it showed my phone needed to be "restored' (again.) Then I got the message that the phone could NOT be restored. Now I have nothing!!! Since none of anyone's suggestions helped and now my phone is dead I think it must be a lemon. I'm giving up on it and sending it to Apple. It's a good thing I never threw out my old flip phone. I reactivated it. Not a smart phone, but it's reliable.

Thanks for the post! I will certainly give it a try! Allow me a remark without deminishing any of the merit of your post: I am afraid this is only a workaround, not a solution. 😟 The solution would be something that stops this behavior of the device, wihout changing our charging habits. Of course this should come from Apple. Again: great post, and I am very thankful that finally someone have come up with something useful!

I'd just like to say that ahs70's post on Dec 1, 2013 at 1:17am on Pg. 9 worked for me as well: https://discussions.apple.com/thread/5338609?start=120&tstart=0

If your iPhone's battery is acting up you need to determine if it's a software issue or a hardware/battery issue. To do that, after syncing your iPhone, erase/hard reset all data and settings from your iPhone to what it was from the factory as new. This can be found in Settings/General/Reset/Erase All Content and Settings. Then test it out for a day or two. If it's still acting up then it's likely a hardware issue and you will need to get your battery replaced. If your warranty is done than check out this link to get a battery kit to replace your iPhone battery yourself: http://www.ifixit.com/Store/iPhone/iPhone-5-Replacement-Battery/IF118-001#produc tDescription

If your iPhone is now working properly after hard resetting it than it's most likely a software issue. This battery issue only started after upgrading to the new iOs7, so it is obviously related to the update not properly installing itself. What has worked for me and many others is to manually update to iOS 7.0.4 using the full downloaded version of the update which is about 1.32 Gigs.

But first you need to find out what model of iPhone you have, click here to determine if it's GSM or CDMA: http://support.apple.com/kb/HT3939?viewlocale=en_US&locale=en_US

Then go here and scroll down to download the iOS 7.0.4 complete update for your device: http://www.downloadios7.org/download-ios-7-0-4-ipsw-file.html

Then scroll up on the download page and follow the instructions of updating your iPhone manually following the instructions below: "IPSW with iTunes"

And your done.

Problem solved.

I only posted this because it was a very frustrating problem that no one really seemed to figure out a solution for.

I hope this helps.
