Phone turns off with lots of battery left

My iPhone 4S has taken to turning off with as much as 30% power left. When I plug it in again and it comes back up, it will indicate the same power percentage. I have made it a habit of draining the battery at least once a month and then fully charging it (probably that happens more than once a month), so I feel like I've been properly maintaining the battery. I got this when the 4S came out, so it's as old as the 4S model is. Oddly, if I'm on the phone this does not happen. It will run down to 1%. Maybe that's coincedence, maybe not.
It's quite irritating - isn't this supposed to be the software/hardware that "just works"? - when you're doing something important and this happens. Today two armadillos appeared in our back yard and I was shooting some video of them. I got a low battery warning - I'm not sure if it was the 10% or 20% warning - but then right after clearing it, the phone shut down. I had some good video, but instead of using the remaining power to save the video, the video was just lost. I had never seen armadillos up close like that and was wanting that video to show my son and some other people, but now due to this problem that video is gone. Thanks a lot, Apple!

Sounds like there is a hardware problem - likely with the battery.
Make an appointment at an Apple Store if there is one nearby to confirm.

My iphone4 turned off with plenty of battery

my iphone4 suddenly turned off with plenty of battery. and my on/off button does not work for me to reset it.

your battery meter is wrong. im running into the same issue without ryhme or reason. my phone was shutting off at 52% like clock work, then it moved to 58%, then finally after being off for half a hour i plugged it in one day and it actually showed 1%. problem fixed.
yet then a week or so later, it shut off on me at 35% and seems to be back to normal again.
the only way i've seemed to fix this is to use the charger that came with the phone or my ipad and have it plugged into the wall and let it say 100% for about a hour past it turning to 100. then when i unplugg it i do a shut down and restart, then i do a hard restart by holding in the 2 buttons until the phone starts to boot up again.
im on a verizon 4s 16g btw. this has been going on for about a month on mine, and just this past weekend my contacts started coming in as just numberes, no names, even if i text someone thru my contacts, the text back to me will come in as a new text under the number and not thier name. again, just randomly fixes it self after soem restarts and reproggraming by calling the verizon number.
lot of frustrations for a 4thgen phone from a company.

IPhone turns off at 25-30% battery left.

My iPhone turns off with 25% battery left and it wont turn back on until I plug it in! I have no idea what's causing this!

^^IGNORE THAT^^
same problem but mine turns off when using camera with 10-45% of battery remaining
shows flat battery animation
will NOT turn back on until i plug charger in, then it turns on immediately showing 10-45% of battery
seen far too many people/posts here about this with NO solution
i had a new battery fitted 10 days ago and its still happening
so its NOT the battery and NOT the firmware
care to explain apple?
or refund me the £300 upfront payment for the device + £38 per month for 2 years!!!!
+ battery replacement fee?
i know its OUTRAGEOUS that im paying this much for a faulty device but my pointless 1 year warranty is no longer valid

IPhone turns off with half of battery

My phone has been acting weird for some time. When the phone's battery reaches half it will turn off and if I turn it on again it wont stay on. But what I noticed is that if I turn on airplane mode this random turning off wont happen. In airplane mode I even turn on wi-fi and I dont get any problems. It's just when the "phone" (or network or whatever) is turned on that it turns off with half of the battery. I already restored it and it didn't help.

If restoring your iPhone with iTunes has not resolved it and you are in the U.S., you can call AppleCare at (800) 694-7466, or make an appointment at an Apple store if there is one nearby.

Power/sleep button broken... iPhone turned off with still some battery, how do i get it to turn back on?

my power button on my iphone 4 is broken/stuck. phone turned off but not because of empty battery so charging does not help to turn in back on. i cannot get the phone to come on. what can i do?

Does the iPhone charge at all or does it stay on the low battery display?

Phone turns off while still having battery

I have noticed that when I have like 15% of bat and I take a picture, my phone will turn off as of the battery is empty. It won't turn back on until I connect it to the charger. It will than turn on immediately and showing the same 15%. Is it a software issue? It has happened a few times already!
Has anyone experienced the same?

I would suggest you to restore your iPhone using iTunes, once that this seems like a software glitch.

Phone turns off, power cycles & drains battery

My Curve 8530 has been turning off spontaneously power cycling then the Blackberry download screen comes on. It will then fully load and when it powers back on the battery will be completely drained. It will do this in the middle of phone calls, texting and browsing.
Any ideas how to fix this?

I had the same problem using MetroPCS blackberry curve 8530, I messed around with the network settings on my phone for hours until i figured out that it managed to stay on when i unchecked the mobil network, which disables the radio signal on the phone. Then I started shutting off every other wireless conections like gps, data, roaming, ect... Then i turned back on the mobil network and it seems to be a fix but you loose out on the usefullnes of the phone..

My phone turned off and it has battery

my phone just turned off , i tried to turn it on , but it doesnt do anything ... it has ios 7 downloaded .... help

press and hold down the lock button and home button, wait a cupple of mins to see if the apple logo comes on the screen if it does then let go of the buttons.

My 3GS turned off with a low battery, and now will not turn on

I have charged it fully, tried hard restarting, tried plugging it into my computer, tried pressing the home button while plugging it into the computer etc.
My question is really about how to contact apple in regards to getting it fixed. This is a replacement phone and it did not come with a warranty (or more accurately, I was too late to renew the old warranty when I got it). However if it had come with a warranty, it would have been within the warranty period (8 months). To me this gives an implied warranty on workmanship and parts. I live in regional Australia which makes going into my local apple store a little difficult, and I don't want to have to pay for tech support for them to tell me that I should try restarting it.
End rant.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Why is my iphone 5 battery dying even with phone turned off ?

Why is my iphone 5 battery dying even with phone turned off ? Even when my phone is fully charged and I turn it off when I turn it back on the battery is drained. Why ?

Completely drained when turning the iPhone on after being off?
All lithium-ion batteries lose some charge when the computer or device is powered off.
If the battery is entirely depleted after the iPhone is powered off with a fully charged battery at the time, something is wrong - unless powered off for a number of weeks or months.

Random reboots when 60% or less battery, phone turns off when fully charged

Hello!
I need help! I have been using my new Sony Xperia Z3C for 4 days now. It came with Lollipop update.
Everything was working great when I opened it, but not for long. It started to reboot more and more frequently and anything could set it of, home button, typing a screen lock PIN, using any app or just while in stand by!! Crazy.
After that frustration I hoped it was a software issue because that I can solve. I started with PC Companion update and after that same thing. Ok, I thought the version is the problem. I went with older versions of Lollipop firmware. Again, same thing, after some time of usage phone starts to reboot uncontrolably. Fine, fine, I thought okay Lollipop is the problem, I need to go with Kit Kat. I did that and after successfull startup and app instalation, account logging and everything, guess what. REBOOT!
Then I noticed the weirdest thing, When I am charging the phone, it works like a charm and when it is almost full. When it drained passed 60% battery level it started to reboot again and this happens every time. When I charge it again it works just fine until 60% again. Other weird thing is that the phone TURNS OFF completely when it is at 100% charge.
Can I fix this at home?
Cheers,
Branko
Solved!
Go to Solution.

Hi Phy,
yes I allready did the SIM card and SD card test and removed both of them but it's the same issue. Sometimes it works for hours without a problem and then it starts to reboot every few minutes. It really has no rules.
I guess considering all the similar topics I read and your suggestions it is definitly a hardware issue.
Thankfully I will get a replacement on Monday.
I will update what kind of issue it was if I get that information.
Cheers!
Branko

Either your battery is failing or your battery gauge needs to be recalibrated. Start by recalibrating:
When it shuts off charge for just a minute or two, then restart (hold HOME and SLEEP until an Apple logo appears). Deliberately run the battery down until the phone shuts off at 1%. If it shuts off above 1% repeat the above until you get to 1%. Then charge for 4 hours with the wall charger without using the phone. This process will recalibrate the battery gauge.
To prevent this from happening again about once a month run the battery all the way down to 1%, then continue until the phone shuts off. Apple recommends this in their battery help article, but they don't say why you should do it. The have some hokum about "keeping the electrons moving." Honestly! The iPad battery tip gives the correct reason.
If this does not resolve the problem you most likely need a new battery. If you are near an Apple store take the phone in and they can test the battery for you.

Why does battery suddenly go to 0 and phone turn off?

I have an iPhone 5 and noticed the following. My battery is showing 30% or more; I start taking photos (with flash) and all of a sudden (within minutes) the phone turns off as if it was completely discharged. I plut it in, and within 5 minutes the battery is showing 40%. The fast charge time and the very unexpected turn-off make me think the battery wasn't really at 0. Am I wrong - could a few flash photos drain a 30% battery to 0, and could an empty battery charge up to 40% in a few minutes (being plugged into a car charger)? Or does my battery need to be recalibrated somehow?

I found out that after it shuts off, the first time I hold the buttons, it shows a charge symbol and doesn't turn on. But if I hold the buttons again, then it does boot! Unfortunately, it then shows 4%, not 30%. I let it run down again, plugged it in the wall for 4 hours like you said. Let's see what it does now. It's just weird how it unexpectedly shuts off long before it gets to 1%.

HT1688 My phone turned off while i was texting. I not sure what happened because the battery was at 72%. I tried turning it on but nothing happened.

MY phone turned off while texting battery at 72%. I tried turning it on but screen stays black.

First, try to reset the phone by pressing the sleep and home button for about 10sec, until the Apple logo comes back. You will not lose data by resetting.
If this does not work, connect in recovery mode, explained here:
iOS: Unable to update or restore
