Interestingly enough, my beloved Nexus 4 just died this past month. I noticed it getting extremely hot, and then one day started a boot loop that I could not fix. I figured some hardware broke. My uncle also picked up one around the same time, and is going through similar problems - overheating and rebooting, though has no boot loop issues. I will warn him of this battery issue.
On another note, I just purchased a Zenfone 2. I accidentally dropped it from about a foot (getting out of the car) and cracked the screen. I noticed most other Zenfone 2 phone that has a cracked screen appears to have it crack in a very similar spot (top right). I guess all phones have their weaknesses. Though, my nexus 4 looked like it went to war and back having been dropped (at excessive heights), and never broke.
