Chosen Solution
I have only had this phone for two months, it’s battery was at 8% when it turned off. When I went to charge it the battery symbol appeared, but then after a while I noticed it actually hadn’t turned on. I’ve tried the home/lock button reboot with charger and with out, but nothing. iTunes on my lap top doesn’t recognise it and yes I have tried different chargers, but still nothing. I’m so frustrated, please help.
If the charger port does not plug in fully check the port for any gunk and if there is use tweezers, toothpick or something equivalent to clean out the gunk carefully. Otherwise there is a chance the battery may have gone faulty.
Assuming the charger, port and cable are all okay, then it sounds like a completely dead battery. Presumably it is a secondhand item and several years old, though you have only recently acquired it. The seller may have got rid of it for this reason. The good news is that replacement battery kits (including the tools) are easy and cheap to get and if you or a friend are up for it, it takes less than an hour to install. Start with a clean table, small pots and tape to keep track of the screws and a good strong light to work by. We did this for my son’s iPhone 5 and it came back to life like a new one and is still going strong more than a year later.
