Sony are supposed to be going to add battery savers to their android phones like they had on there notebooks, like stop charging at 80% or less maybe if will is user adjustable, I have been looking for a hardware method to stop charging at 80% for 5 or 6 years but not a sniff, So i have to use an app to sound an alarm and manually pull the cable out myself.

Well i am going to give 30-70% setting a go for my charge alarm, I was using 20-80% up to now.

[...] I charge to roughly 90-100%, let discharge to about 30% and depending on usage, so one charge lasts 3 to 6 days. A 100% to 10% would last a week [...]

If you want to automate partial charging and you know how to program Android/iOS then you could use a WiFi controlled relay (e.g. below) to switch your charger on and off when it reaches the desired SOC, e.g. here's an $11 1-channel version on eBay USB 5V DIY One Channel Jog Inching Self-locking WIFI Wireless Smart Home Switch
