  I’m more peeved about the soldered batteries. They still expand! What are the big-battery people doing to get 22 year life that can't be downsized for small batteries? Is there some fundamental reason we can't have mobile devices where the battery is good for two decades?

    I think it's charge percentage. My Kia Niro seems to keep the battery between 50 and 80 percent charged. I've heard that the Tesla does similar (perhaps showing full when it's really 80%). This seems to be the sweet spot for these batteries and smart charging controllers can keep them alive longer. Our phones are under powered though, so the batteries are stretched to their limits and therefore don't last as long.

      Actually my work laptop is expanding because of its battery. It’s had some usage but nothing like a phone. It’s usage isn’t far from what you describe but with considerable time kept powered. I’m thinking it could be heat related. That machine heats up because I use it for “desktop” tasks. But Apple long ago stopped making laptops aimed at being cool internally and cool to the touch.
