Not being able to change the battery is planned obsolescence, that is all it ever was.
I'm holding tight onto this phone, it's awesome.
Edit: sorry for offending the downvoter - I actually like that phone, yet there I was with a wet brick.

Waterproof.

The back pops off just like a Galaxy S3. The battery itself is not just removable, it also charges wirelessly. Micro SD and of course a headphone jack. It was also the first quad core LTE on the market.
ps: also, yeah, water sealed electronics is very valueable. And when you do need to replace a battery, a tech could swap it with a few tools. Not user replaceable but still replaceable at low cost.
Also, I have external battery charger for LG G5. I can use my phone freely while my other battery is being charged.
You don't face water probles every day but you face charging problems every day.
Also when my battery dies I don't need to wait someone to change my battery. After all I already chage my battery every day.
Most people use cases anyway, and space is at a premium on the inside of the phone. Not so much on the outside. Plus, battery cases can be used without shutting down and turning the phone back on.
Speak for yourself. I have water problems about as frequently as I have low battery problems.
For example, I have an old GPS+HRM runner watch which is water resistant but not fully water proof. After a run I briefly wash it under running water (not submerging, but heavily splashing and using soap). I have been subjecting this watch to such abuse for years and it has not failed yet.
I think for most users water resistance would be just fine, although this may be just a personal bias.
If the phone catches on fire they're on the hook for it.
Plus phones have a two year designed for lifespan. So it isn't a priority in that sense.
And users like phones looking sleek etc. A phone reviewer is going to note that a phone is bulky if it has a replaceable battery.
