These udev rules stop charging the battery at 80% and resume charging below 70%.
However, once charging stops, the battery starts discharging even when connected
to a charger. I have not yet found a way to enable trickle charging with the
qpnp-linear-charger driver. There seems to be a "qcom,float-charge" Devicetree
property, which may or may not be relevant.
