I spotted a setting where it keeps the battery charge
readings when powered off and continues at that point.
There is no such setting, it is always active...
If right after start (power off/on) it detects the battery it loads stored metrics..
Note: battery should be already connected to green terminal, before power on PSU...
Metrics (Ah, Wh, Time) are stored one time per minute, while charging process.
Im fairly sure the battery charge value stayed even when the unit is powered off and did not reset to zero.
Currently it resets when the battery is unplugged.
It is stored in MCU Backup registers (BKP)...
Powered by battery, same as Real-time clock (RTC).
The backup registers are forty two 16-bit registers for storing 84 bytes of user application
data.
They are implemented in the backup domain that remains powered on by VBAT when the
VDD power is switched off. They are not reset when the device wakes up from Standby
mode or by a system reset or power reset.
Just wanted to know how much power I have put into a battery if charged intermittently and taken off charge
inbetween. Does that make sense?
I do not quite understand what you want...
Switch off option "Reset metrics" in Charger menu, and it will not automatically reset metrics, when detect the battery.
But in this case you will have to reset it manually, by pressing "MEM +. (DOT)"
