I said I was done with this discussion but I had to drop back in and answer this logic. For some reason I stopped getting Email notifications and didn't realize this thread had continued.
No, my iPhone SE is the FIRST iPhone I have owned. I bought it because I wanted a smaller form factor phone than was available in the Android world and at $149 was too good to pass up. I like the build quality and hope to get a couple years minimum out of it before I choose to upgrade.... either due to diminished battery life or desired new features. I also chose the SE because if I ever do need to replace the embedded battery it does not look that difficult.
You all missed my point re: replaceable batteries..... it has NOTHING AT ALL to do with wanting to be able to swap on the go for longer run time. I find the run time (with a new battery, at least) on the SE (as well as my Android and Windows phones) is better than I was hoping for and is very acceptable.
What I want is the ability to replace the battery.... the ONLY life limited component in my phone.... when the performance drops below whatever I determine to be my personal minimum. Yes, you can do that with an iPhone but $79 to have Apple do it is a LOT higher than what it would be if the battery was simply considered a spare part and user replaceable.
As for all the assumed negative trade offs to return to user replaceable batteries...... go ahead and believe what you want. If you don't believe it is possible to design a water resistant phone with a replaceable battery, I probably can't change your mind. If you are happy with non-replaceable batteries, that's fine too. I only started this thread in response to the multitude of complaints about phone performance degradation due to degraded batteries. Making them replaceable would make all of that go away and it seemed a logical time to bring it up. If you don't agree, fine.
Sorry if I bothered you all.... I'm a retired engineer and by nature I'm kinda hardwired to identify and solve problems

Returning to replaceable batteries and retaining things like water resistance is very possible so it seemed natural to bring it up. I'm real sorry I did
