Nokia Lumia 810 - My Lumia's battery does not get fully charged

  1. Use the Nokia battery charger that was included with your phone. Older chargers may not fully charge the battery.
  2. Reset your phone. Press and hold the Power and Volume down keys simultaneously until you feel the phone vibrate. After this operation, you may need to set the date and time on the phone. Note that this does not remove any settings or your personal content.
