So when I unplugged my phone after a night at work, I noticed it was pretty warm. This isn't unheard of since I use it to stream music over the course of the night, but it is always plugged in, so the battery is always around 100%. Anyway, after picking up my phone after roughly 7 hrs of sleep, I noticed the phone was too warm, and found the battery at 30%(!). I immediately checked to see which apps were eating the battery and found Google Play Services and mm-qcamera-daemon had 23% and 22% respectively. Rebooting the phone seemed to take care of the warm battery and power consumption, but I'm still a bit curious why those two apps seemed to randomly get so power hungry - any thoughts?
