More about how you are always thinking about the battery level and where you next charge is... At 70% battery health my mobile phone is a lot less mobile!
A big part of non-removable batteries is gaining that all important water resistance/proofing rating. It’s a huge selling point that you can drop your £1000 phone in the toilet and it will still work.
Phones are mostly glued together now, change that for a removable back and kiss goodbye to waterproofing.
Have had my electric for nearly four years now, and don't think about the charge level any more than I did the diesel level back in the day. I don't have to lug spare cables or battery around either (yet
Weird thing is about the waterproofing on mobiles, they advertise it as a thing but then refuse to guarantee them if they get wet.
