Droid Turbo 2 running Android 7.0. Yesterday I noticed some odd behavior on the phone so before I went to bed last night I powered the phone off then turned it back on to reset it. The phone had been charging for the last couple hours and the battery was nearly full – it showed 97% when I powered it off.
When I turned the phone back on, the “Motorola” splash screen that first displays stayed on for several minutes, and never completed the startup. (Normally the Motorola logo will change from a white to black background after a few seconds, then a Droid logo is displayed, then finally the desktop displays). So I powered it off and on again, and this time it restarted normally, but then I noticed that the battery was down to 78%.
This doesn’t happen every time I restart the phone, but it’s something I’ve noticed more than once. What could be draining the battery that fast during a restart? Even during my most resource-intensive phone usage, I don’t think I’ve ever seen the battery drain that fast (20% in about five minutes).
