Thick is easy. Get a battery case. I used to have one that allowed for swappable samsung batteries packs that was great.

Getting flashbacks to the HTC Evo era and having a thick ass battery case lol, before that i'd have to swap battery like twice a shift.

A battery case would work too. Was just hoping for a model that is trimmed and optimized for longer trips outside the city/with absence of reliable power sources. Cut some of the performance, only efficiency cores, bigger antenna and optimize hardware aggressively for low battery usage. Maybe use some of the bigger case for repairability…
