Chosen Solution
Alright so my phone has always had a battery problem. By that I mean my battery would be randomly low. For instance, I could charge it for an hour and it’ll be 100% and as soon as I take it off the charger it would be on 70%. In the past when my phone has died completely, it would take an hour or more for the phone to come back on after being on the charger. Yesterday, my phone was freezing up so I willingly turned it off at 50%. I let it sit for about 10 minutes before turning it back on. When I went to turn it back on, it showed the low battery symbol. So I plugged it up to the charger and let it charge for at least 2 hours. But it still wouldnt come on. I tried pressing the home and power button at the same time but when I do, it shows the low battery symbol. So I gave up and let my phone charge overnight, hoping it would turn on at some point. My phone had been on the charging at this point for about 8 or 9 hours and it still wont turn on. What do I do???
When plugged in, do you get the battery symbol come up on your phone? iPhone 5 has known battery issues. If the phone registers the cable, I would look to replace the battery (genuine Apple replacement only) AND then also restore the iphone via iTunes, and set it up as a new iphone If it doesn’t register the cable being plugged in, try other cables / charging plugs, then look to replace the charging port. You can get more help at the iPhone Won’t Turn On wiki. Good luck!
Heat it up with a hairdryer, it will work Update (08/25/2017) –To prevent confusion, this is a reminder that this update was by another person.– I honestly don’t know why this would work, but being that it has helped people, I want to remind everybody: DO NOT HEAT YOUR BATTERY DIRECTLY! This is extremely dangerous. Maybe @philipengel could elaborate more on what he heated and for how long? :)
In this situation it is always hard to judge exactly where the problem lies. To me, this sounds like a battery failure. You can buy the battery here: iPhone 5 Battery And the guide to fix it can be found here: How to replace your iPhone 5 battery Hope this helps! And good luck, happy repairs to you :)
The hairdryer will help for a short peroid of time, to resolve it permanently we need to work a little while longer :) How to repair not charging or quckly discharging battery issue in an iPhone 5s
It is seems that your power supply circuits are fine that means your battery and battery connector are working fine. Battery symbol shown on screen. So display assembly are also fine. Now your iphone wont turn on or not booting up is your problem. Have you connected to itunes does it recognize by itunes. try to force restart your iphone. or try to enter in dfu mode. But first i want to know that your iphone is recognize by itunes or computer or not. If it is not find by computer than some basic hardware failure is there or may be os corrupted.
this happened to my phone a few days ago and i did the hairdryer trick and it worked but my phone stopped working again today and so i tried the trick again and it doesn’t seem to be working so what i suggest is using the hairdryer trick as a semi permanent solution but my phone is already really broken so that should last you a while and if it happens again try the hairdryer trick and if it doesn’t work i suggest getting a new battery for it
