As long as you can replace the battery in a smartphone you should be good for a long time. It's the battery that always seems to die before anything else, at least in my experience. And modern lithium ion batteries seem to bloat more then older lithium ion batteries in my experience. I still have my old GBA SP battery in my SP and although the battery isn't the same capacity as it once was it hasn't bloated like every modern phone battery or mobile device seems to do these days. I assume it's the increased capacity and density?

Obviously try not to drop you're phone on the floor all the time and it will last a good while.
