Yep, and what would be even more sensible is allowing users to 'cap' the charge level the way Samsung has started to with a "charge only to 85%" ability. Don't just respond to aging batteries, allow steps to reduce aging.
But, that goes against the upgrade sales process.
You can kinda do this with AOSP, but it's obnoxiously convoluted. You enable the adaptive charging feature, then set a silent alarm for 9:59, then set an alarm on something other than your phone so you can unplug your phone at 7:00 or so. (edit: or I guess you could get a smart outlet to cut power to your phone at 7:00)
Have you considered your own bias? Apple automatically caps battery charging at 80% but it is algorithmically controlled instead of a manual toggle. I would like the manual target, too, but if your narrative were accurate they would not have implemented the feature to begin with.
Well not having battery charge control locked behind root as is now typically on android would definitely be a good first step.

These are the same problem. Nominal voltage lowers as batteries age, as does the ability to maintain a voltage under load. The batteries were "fine" for the first year. A larger battery would have been able to keep voltage under load at an acceptable level even as it aged.
> I expect the battery on the 13 to be bigger because I assume (with no research, admittedly) that the SOC and screen both take a good bit more power than the equivalents on a 6S.
And yet the 6 had a larger battery (same screen size). Personally I find the 6S (and 6) to be very thin. They could have easily been a couple mm larger without the consumer noticing (Apple could have made the camera lens flush!).
