I think I know why most telephones do not have replaceable batteries!
Let's say you hijack a plane, and steal all the people's phones, then take out all their batteries, and link them in serial, then short circuit them... you have a bomb (Somebody set up us the bomb. Make your time!)
Thus: making the battery replaceable is helping the terrorists!
All new batteries are higher density. Thus, more explosive. So the phone is a harness, it doubles as a containment unit should the battery explode... adding an opening into that weakens the structure...
Safety first!
