How can we prevent a battery from fulling charging? We plug a car/phone in at night, and wake up to it 100% charged.

Tesla's cars have a charge limit you can set, after which the car simply stops. I believe they come by default at 90%. You're supposed to override it if you want to go on a long road trip.

Would be cool if there was a similar feature available on phones. Maybe you could rig up something with Tasker or the like on an Android.

It looks like Sony's Android phones have this option https://www.phonearena.com/news/Sony-Xperia-Marshmallow-upda...

Interesting fact.. with the last software update they changed what was considered trip, and local pretty significantly. I wonder if that is aligned to a SW improvement in battery management?
