For me, the battery charge calibration of Librem 5 gets off quite rapidly, measured by
- upower, that after only a day or two shows a growing discrepancy between
energy-full
andenergy-full-design
Easiest way to view just that:upower -d | grep energy-full
- the fact that battery drain below a certain percentage happens very quickly
This results in the battery percent in the indicator bar quickly becoming unreliable and that the phone usually has less power than I think it has. It could also mean, but I am not certain about this, that the phone believes it is fully charged before it actually is.
I know the “energy-full” drift can partly be explained by different charging cycles, where less frequent charging is preferable. However, I like to wake up to a fully charged phone and therefore charge throughout the night. I also like to have as much charge as possible when I leave home to reduce the likelihood of the battery discharging completely before I return.
I am aware of discussions on this forum about different ways to recalibrate the battery charge by various lengthy processes involving turning the phone off, remove/reinsert the battery while phone connected to power, etc. My preferred way of doing this is simply turning the phone off, remove/reinsert battery and let it restart. After that my energy-full
and energy-full-design
always align perfectly.
I am confident that there is or soon will be a better way of coping with this on the L5. With the current battery drain even with the phone idle (I fully respect the challenges with this), I don’t want the calibration issue on top to make the situation even less optimal.
