Best way to bring back a dead battery?
I have an iPhone 5s which is not working (won't connect to iTunes or power up, and it has a shattered screen).
I don't really have a desire to spend much money on fixing this phone so I am trying to do everything possible before ordering new parts.
I suspect that the charging port/battery is defective. Therefore, I've been googling online to try and find a way to 'boost' the battery back to life. The simplest way I have found is to heat it up with a hair dryer then plug it back into the phone.
I'm wondering, would this be safe and is there any other method/thing I should do to troubleshoot/fix the phone (without ordering new parts).
