Looking at my battery history, the automated version has my phone sit at 80% all night, and leaves it at 100% for only a couple hours in the morning. I suspect this will be a fairly negligible impact on battery longevity for me, and most users, without the severe inconvenience of a 20% reduction in battery life.
It would be nice to know how the longevity math works out.
- Mawr 3y agoUnfortunately, it's not possible to reliably automate this. A phone has no way to tell how it will be used after getting charged. It can try to detect some usage patterns, but it'll just be guessing, so even in the best case scenario it must remain conservative. This is one of my pet peeves - obvious and easy to implement features that are just not there. I literally only switched to iPhones because the blindingly obvious Emergency Bypass feature [1] wasn't available on Android. Phones already perk up when connected to a power source. Why not display an optional dialog with a choice of either the desired max battery level and/or some user-friendly modes like "battery health" vs "battery charge"?! Easy to implement, zero downsides, massive upsides, nobody's doing it.
