I had many problems with my RPi2 not booting after reboot. I had to unplug it, get SD card out, fsck and clean dirty bit and hope that it would boot. Got to making backup image every week. I had some unstable power (not affecting any other home electronics) and was looking in some UPS hat but opted to go security DVR way. Bought 7Ah battery and 70W buffer PSU[1] and DC-DC 12V to 5V supply[2]. Could not be more happy. Random problems with SD cards are gone. Only thing to add is some battery voltage sensing to gracefully shutdown RPi in case of longer power outage. Thus, I can tell that many problems with RPi may come from inadequate PSU. 1.
