Sailing mode to prevent trickle charging #289

Open jk-aus opened 1 week ago

jk-aus commented 1 week ago

Battery does a great job of limiting charging or manually discharging to a set percentage but could a feature like Al Dente's sailing mode be added to prevent trickle charging when the laptop is plugged in and has reached the specified charging limit?

Instead of just setting a "battery maintain" level, a charge limit level and a charge restart level would be set so the battery could drain down to a set point before charging restarts. e.g. limit of 80% and restart point of 70% so the laptop charges to 80% and then uses power from the adapter but the battery is not being charged until its level slowly and naturally drops to 70%, and then charging restarts.

As it is, the laptop charges to 80% and then uses power from the adapter but is fairly constantly topping up the battery to keep it at 80%.

As far as I understand you are looking for an adjustable hysteresis in percent. Currently it is coded at 1%. I implemented it as second argument for voltages limits: E.g. battery maintain 11.4V 0.2V This will stop charging at 11.6V and restart at 11.2V.

It could also be implemented for percentages like so: battery maintain 75 5 Which would lead to your example of 70%-80%

Hi Rene, having looked up what adjustable hysteresis means, yes, that's what I'm talking about. It's good to know it's already there with a ±1% swing.

Are you saying v1.2.2 can already use the "battery maintain 11.4V 0.2V" instruction and that a future release could have the ability to use the "battery maintain 75 5" instruction? If so, the percentage example seems less technical and more user-friendly than the voltage example. I think the percentage approach would be a valuable addition.
