@WhatTheChel @RickiTarr The last high end phone I had with a replaceable battery was a LG G5. The base of the phone popped off and you just slid the battery out. Very easy to carry a spare. They made an small holder for a 2nd battery which acted as a charger and a battery bank, so you could just carry a second battery along with you and just pop it in when you needed. Loved the concept and sad that it was sort of their last gasp.
