Removable battery is #1. My old Galaxy S3 (not even my first phone-yes I’m old) has absolutely godawful battery life but I had I think 4 total batteries around to make sure I could always have it even on a heavy use day. That sucked, but at least it was doable with a really easy process (peel off plastic back, pull out and swap battery, snap the backplate back on).
I keep an old phone around and sometimes use it to play like a video for my cats to watch if they’re laying on my bed when I’m not in there. But it has to stay plugged in because it loses the first 20% in about 15 minutes.
And that phone in particular (a pixel 2) is particularly a pain to replace the battery in the first place.
I was using it with a 3070 just fine. Not necessarily sold on it, but so far so good.
I mean it’s dead, (for now) because my CPU died to the fate of belonging to the wrong Intel generation.
Now after finding a lottery ticket I will buy a new board and CPU, and a new GPU next in priority (since it does still work, but I won’t be buying Nvidia or Intel anymore.
