Maybe the BL-T34 is easy for guys like you and I, who are willing to brave heating, and separating the phone to replace it. I am not so sure about others.
But, you may have a poi9nt. I'll never run out of battery. That was the problem with my last three phones at some point, battery simply will not hood a charge.
But what I was really hoping for was a bump in RAM. I briefly had a Xiaomi Mi Mix 2 and it was FAST. It just didn't have the features I wanted. I am basically a star trek nerd who wants to be able to operate my phone totally hands free using only voice commands whenever I want to. I previously had the amazing Motorola Moto X Pure, (Perfect voice command moto voice. Just too slow, and battery problems) and I go the LG specifically because I can operate it hands free when I want to.
So I guess I'd like something like what I have with twice the RAM.
Thanks.
