HTC One Max Troubleshooting

If the charge in your battery is too low, it will not power the phone. The first thing to try when you phone won’t turn on, is to charge your battery. Plug the phone into your wall outlet and leave for 10 minutes, then try to turn it on again. If that does not work, leave for another 20 minutes and try to power on.
