It does not have a removable battery? I consider this as an important feature me that I spend lots of hours outside the office. Also ejecting some mass when the phone drops is always a good thing. Two broken Iphones on my drawer say so.
It's not a "removable" batter, but it is easy to replace with the correct Torx screwdriver. That doesn't help in your two scenarios, but it will be useful if you want to keep your phone significantly longer than the 3 year half-life of lithium batteries.
