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 ). It's like anything else, it's just managing things.
Weird thing is about the waterproofing on mobiles, they advertise it as a thing but then refuse to guarantee them if they get wet.
