In fairness you can remove the battery from any phone.

Materials:

1) Claw hammer

2) Phone

edit - so this post isn't entirely silly:

I'm with chenliangchen, in that my main 'dealbreaker' is a non-removable (erm... you know what I mean) battery. In fact I probably would have bought the Yotta Phone 2 instead of the Jolla if it had had one. I don't regret taking a punt on the Jolla now, of course (although sometimes it tries my patience )
