New iPhone 5s shut off unexpected and won't turn back on

so this happened I got a secondhand Iphone5s and its only 6monthold from my friend the appearance is all good and the battery is so fine and it looks so new and it works so good but after 2 months of using my iPhone it gets a lot of issue like battery heating and unexpected shutdown I tried restoring my phone using iTunes sometimes it restarts when I'm in the middle of restoring my iPhone I did it many times but my iPhone keeps on restarting I really don't know what happened I tried also go to mac center and explained to them what happen to my phone they said there's an issue with the hardware can you guy help me out? I really need your help

i have the same problem, but when i perform the possible solution, it did not worked on my phone 😟
is there any other solution?
i just left my phone in my bag, and when i get back and tried to check my phone, i just saw it turned off.
when i tried to turn it on, it did not turned on.
i tried to hold power,volume up and down, together with the power button, but it didn't work.

please help.

is this something to do with the battery? i still have 55% before i left my phone.

I just experienced the black screen shut down for the first time. I held down the home button & the start button for about 90 seconds. Then the white scren appeared with apple logo. i then pressed the start button. then everything was back. Your solution worked great! I love my 5s it has been flawless for 3 years. It feels so good to have a community of fellow i phone users who share their knowledge of apple products. i hope to contribute myself one day. Thanks

My phone just did this a few seconds ago and I was so terrified as I tried pressing the Home Button then long-press the Power Button but nothing happened. I then tried to press and hold the Power Button and the Home Button at the same time and a few seconds later I could see the Apple logo and I unlocked the phone and everything was back to normal.

Hello Keith,

Congratulations on your new iPhone 5s! I would be concerned too if my iPhone shut off unexpectedly and would not power on. I found an article with steps you can take when you encounter an issue like this. I recommend following the steps below:

Will not turn on, will not turn on unless connected to power, or unexpected power off

1. Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
2. Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
4. After at least 15 minutes, if:
   • The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
   • The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
   • Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
5. If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
   • If the display turns on, go to step 4.
   • If the display remains black, go to next step.
6. Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

a i tune menu. just switch off you i phone again holding power button, then again on you i phone its work fine

Thanks.

Worked! Thanks a lot.

Pressed all 4 buttons for ~ 20 sec until an Apple logo appeared and quickly disappeared. Then I released the buttons and I could turn it regurlarly on again.

Worked for me too. Thank you for helping me to resolve my issue.

Best wishes.

Thank you so much. I was freaking out that I somehow 'killed' my phone, but holding down the powerbutton, homebutton, volume up and volume down at the same time for around 15 seconds worked. I cant thankyou enough.

my friend had this problem, she had to plug her phone in and then do the reset where you hold the home and power button down for about ten seconds or so.

Hi Everyone,

Thank you so much for the information. 🙂 I held down the power button and the home button for about 45 seconds and the phone started up. When it came bak on it said the power was at 85%. I did just update the software yesterday. I have never had a problem like this before and have had an iphone for years.

Hi Everyone,

I just want to tell about my problem with an expected shut down a few minutes ago.

Actually I got panicked for seconds then I logged on to here to search for a solution then I did the following:

I held down the power button along with home one for about ten seconds then it went back on.

This is the first time I encountered such issue taking into account one thing that I just updated my iPhone 5C to the latest iOS 7.0.6 two days ago so now the question is : does this problem has something to do with this latest iOS update?

Thanks

We'll one more thing to add that after the new update I went to charge my iphone and a weird thing I found that battery percentage was 100 % but when I unplugged the charger battery percentage was reading 97% then I left it for more half an hour but same result.

Any idea about this issue and my above posted reply regarding unexpected shutdown ?

Is there a relation with the new iOS update ?

Thanks

thank you so much 🙂

Thanks so much!!! This just happened to me 5 minutes ago and I almost had a heart attack!!! 😮
Thanks for the help!!! 😁 😉
