Test the battery using the HTC Android diagnostics menu

Follow these steps to find out if your battery is failing.

Make sure the phone is fully charged before beginning.

  1. From the home screen, tap Phone.
  2. Dial *#*#3424#*#*
  3. Tap ACCEPT.
  4. Tap More.
  5. Tap Battery Test.
  6. Tap RUN.
  7. Tap the Back key twice.
  8. Leave the phone alone for an hour.

If, after the hour test is complete, the battery has dropped less than 30% of its total charge, it is deemed to be working within acceptable limits.
