There are many rumors. Some say that the best thing is when the display is always between 20 and 80% … Others when you fully charge it and then fully discharge it…
I also wonder whether the power that is currently being used by the PC comes from the cable or from the battery when I use the notebook and charge it at the same time. What is gentler for the battery so that it lasts longer?
If it is possible in any way, remove the battery during mains operation.
RWTH Aachen has researched this and found that a charge between 30% and 70% lasts the battery life the longest.
Maybe you can try lowering the brightness of your laptop. A bright brightness consumes a lot of battery!
If you actually use and charge the device at the same time, it will share the current. Partly from the battery, partly from the network.
With most devices, the power of the power supply alone is not sufficient to cover everything and to charge the battery at the same time. So there are always interruptions in the charging process. This is called microcycles, which are anything but healthy for the battery.
