You can get a gizmo called a Chargie that lets your phone control charge rate and max charge% over Bluetooth to this little interposer dongle that sits between the charger and phone. Getting enough to equip all my usual charge points would exceed the cost of a replacement battery, but I guess if they last for more than one phone it's possibly worthwhile.
