I installed the HTC M8 system update and ever since, it sucks the battery life from my phone!! It will not hold a full charge longer than 3 hours. Are you aware of this issue and will there be a patch sent out to fix it?
Danmo21, let's get this battery issue figured out. Does the device take any longer to charge than normal? Are you using the original charger that came with the device?TimothyS_VZWFollow us on Twitter @VZWSupportIf my response answered your question please click the "Correct Answer" button under my response.
