My phone was on 35%battery, put it to charge and it automatically switched off. Several attempts were made to get it powered up but no success. I tried all the tricks with the toggle buttons, still nothing. The HTC android screen appears…then shuts downs again. The battery sign comes on showing 0% stays for a while then nothing. I tried several different charging cables no change in the phone. The phone is only 18months old, however i have experienced a bootloop once before. Any suggestions to fix would be greatly appreciated.

Try to access recovery mode so we can do a hard reset with the guide below. https://www.hardreset.info/devices/htc/h

If the battery is low (under 70%) nothing works anymore. Only external USB power will help. The battery power can drop from 100% to 0% within two clicks, starting an app and the phone shuts down. To fix this: battery replacement…
