Re: Pointless
The last few years' Xperias has had a "battery care" feature that does predictive charging. It looks at when you usually go to bed or plug it into the charger and when you get up. It'll charge up to ~80% initially and leave over night to top up to 100% about half an hour before your get up. They claim that doubles the battery's life span. My current phone is getting to two years old and I've not noticed any decrease in battery life/capacity. It also monitors your use during the day and will warn you if it looks like you'll run out before your anticipated charge time so you can enable stronger power saving features if you need.
