    i updated my Lumia 920 to GDR1 update yesterday. Battery changes from FULL down to half when rebooting. Charging it again and rebooting its full again.

    This needs a fix. Please

    This is very normal after any update, just recalibrate the battery by letting it die then charging it to full. And wait a couple of days after the update so the battery usage will go back to normal.

    Wait for the phone to settle down. It'll be back to normal in a few days or hours.
