My iphone 5 shows that it is charging when plugged in but it doesn’t turn on. It shows that there is 0.39 amps going to the phone i have changed the charger and plug but no successes.

0.4A on charger output means it should be charging the battery. Try another battery. Sounds like voltage isn’t going up on battery.

Hello Try holding home bouton abd the power until the logo appel show up Otherwise plug it to PC and to restore Good luck
