And when it's hot your battery runs out, too, right?
Mine has started doing that, and I can't get it to stop. My phone has now run out of battery in mid-day, after spontaneously getting all hot for the second time this week. I rely on a phone for business, and this is unacceptable.
Download the tiny app "TOP" it will tell you which process(es) are using the cpu. for me it was something like system.android.acore and something. something.google.gapps.
My next step will be to do the Factory reset.
What I don't get is why it is so random. Happened Wednesday, and persisted all wednesday despite powering down, battery pull, etc. Then Wednesday night it spontaneously stopped running the cpu at 100%. Thursday was fine, a good 18 hour battery day, phone nice and cool. Now Friday at 2 PM, phone gets hot, by 3:30 battery is dead..
I am starting to hate this phone even though I love it.
