I dropped my FairPhone 5 from a bicycle on unwelcoming pavement at good speed. Broke the camera glasses, the screen protector, the carry case and the back cover. It looked positively destroyed and my first thought was “yay, it’s repairable”. Repairing was easy enough and aside from some war wounds on the side of the case (scratches) it’s as good as new. I’m glad I got this phone.

Aside from being repairable, I also appreciate the e/OS support.

Battery temperature management seems to be a key limiting factor.

At least a few years ago, and likely still, the reasons and conditions under which the barrier layers in the battery degrade were not super well understood. Heat seems to be a key contributing factor and charging a battery quickly warms up the battery and I suppose not fully evenly within a cell. Not knowing the complete extent of this makes the early LEAF’s lack of actively cooled battery a reasonable choice. Before that, the batteries of earliest Prius cars held up way longer than expected.

Like with a phone: heat and cold is not super awesome for the battery. It seems heat is especially bad for longevity.
