A friend recently told me that it is important to not charge the laptop battery fully, so that it lives longer. I didn't know if that is true, and if it is I would expect the battery hardware or the OS to handle that without me fiddling with it.
To back this claim up, here's a quote from Lenovo's Vantage Tool on Windows:
If you primarily use your computer with the AC adapter attached and only infrequently use battery power, you can increase the lifespan of the battery by setting the maximum charge value to below 100%. This is useful because batteries that are used infrequently have a longer lifespan when they are maintained at less than a full charge.
I have a ThinkPad X1 Yoga with Ubuntu 18.04, but I expect the answer not to be strongly dependent on the laptop model and the Ubuntu version.
What kind of battery management is preinstalled on Ubuntu without further configuration?
I am thinking of things like the following:
- stops charging at XX%
- warns at low battery
- hibernates on critical battery level
I am worried I might be destroying my battery's life by leaving the laptop constantly plugged in over a few weeks.
In the case that Ubuntu does not already have precautions set up, please also mention in your answer a suggestion regarding this.
