"On my Samsung you have to almost destroy it to get the battery out. A lot of phones have that issue"

Which Samsung?? I have several Samsung Android devices (but not a phone). Accessing the battery is dead easy. There are several videos on YouTube that show the technique.

The S7 is glued together pretty tight. Check out iFixit, they have teardowns on about everything.
