The answer is that phones really need a user setting to enable a charge limit.

About 4 months after COVID hit and I started to WFH, the battery in my Pixel 3 started to swell because I had allowed it to basically live on the charger all day, constantly at 100% battery. Also, by that point, a 100% battery would only give me about 2 hours of screen time.

A few months ago, I got a Pixel 6 Pro, and I'm basically just charging it from a weak 500 mA USB port a couple hours each day, keeping the battery between 50-80%. I'd really like to set an 80% charge limit and just forget about it.

AccuBattery gives an audible alert when a configurable charge level is reached (default is 80%). Not as nice as having the phone stop charging by itself, but at least I'm not frying my battery.
