I’ve been using the 6a since the start of this year, and alongside it Accubattery to remind me to unplug my phone whenever it reaches 85% charge.
I know Accubattery stats are just an approximation, and I’ve only been using this phone for half a year, but still quite amusing to see the battery health go up instead of dropping.
My oneplus has a charge limiter that i set to 90% so it never goes above it and i have an app from fdroid called batterybot that alerts me when my phone drops below 30%. So my phone spends 99% of its time between 30% and 80% charge.
