One of the ways to fix the HTC One M8 slow charging battery issue is to enable (EPSM) Extreme Power Saving Mode.

  • Using your two fingers swipe down from the status bar and open Quick Settings
  • Then tap Extreme power saving mode and the feature will be enabled.

But, if you don’t have the feature on your HTC One M8, then

  • Go to Settings on your phone
  • Tap on About Phone
  • Next tap on Software Update and update the device with the latest version available. 

As the phone is updated, you will find the EPSM feature on your device, then go ahead to enable it.
