Shutting off with charge still in phone.
Have a used iPhone 4s. Problem was short-ish battery life, and then shutting off at 20-30% battery life.
Replaced with iFixit battery. And backed it up to iTunes, and did a DFU restore, and then restored the data
Problem still exists, where the phone will shut off with ~25% charge.
Any suggestions?
Is this a good question?
Maybe bad defective battery and or software related
Did you set up as new iphone or restore from backup
