Graph of the battery charge level

[Quarnero]

BQ25890 works by itself during reflash process, under Jumpdrive … either when connected to some computer USB port and where BPP-L503 battery cell actually discharges itself (at slower rate, yet discharging while needs to add above 0.47A necessary power that i.MX8 MQ and its periphery are requesting in order to successfully complete the job/task):

After some more investigation it seems like the dock is providing less power than the phone is consuming, so it’s technically true that the battery is discharging (at the same time as it is being charged).

or even when actually charging this Li-ion battery as connected to adequate power supply/bank/dock, isn’t it?

And yes, I already gave + to @dos post here for some reason:

@dos

There are two things at play there - gauge calibration and its configuration.

This very kind advice applies here as well (providing correct answer), I’m quite sure:

@nicole.faerber

The charging after that in powered-off mode is just to avoid power budget interference with the charging, charging should then take place form 0% to 100% in one sitting and with the full charge current (which could get reduced otherwise if e.g. an OS is running).
