    This is the second time it's happened to me on Lumia 920. I went to sleep with around 95% battery, woke up with ~55-60% (abnormal amount of drain). Restarted the phone, and the battery shows 86%. What happened?

    Have had this happen a number of times (other times on restarting I have had it diminish as well)... seem to be a calibration issue.... some people mention letting the battery completely drain out once and charging it full again.... but not sure if that will help...

    Letting the battery drain completely, restarting the Phone again without charging and letting it drain completely again will solve it for the most part. Its still not 100% correct but for me the difference is now about 4% while it was 20% at the start.

    How do I drain the battery completely and restart the phone without charging?
