Hi folks,
Today I share an interesting find with the PinePhone's battery profile when using it with the convergence dock.
I've installed Cronie and shell script which sends the battery voltage and level (percentage) to my RPi server every minute. (from /sys/class/power-supply/axp20x-battery/)
The server then is able to plot a graph of these measurements.
When fully charged (at 86%, due to the 4.2v safety limit being applied) and plugged in with convergence dock (USB-c charger, HDMI display, usb keyboard/mouse, media playing so it won't go to sleep), the graph reveals that the battery does not stay at the same level but constantly discharges and then recharges again.
With a laptop for example, this does not happen. It stays at 100% and the voltage is constant.
How does this affect the battery in terms of longevity and efficiency?
