Left side not fully charging

I have my left side connected to the right with the bridge cable.
Right side connected to the computer.

I have the below in my $oninit

set battery.chargeLimit full

My left side won’t charge past 90% I am looking at it now and I see “90% 100%” and no lightening bolt to show that the left side is charging.

Firmware is 14.2.0

Anyone else having problems recently with the left side charging? It was at 76% this morning so it obviously increased at little.

If I have the bridge cable connected and I connect both sides to USB then I also do not see the left side charging (90% 100%) however if I removed the bridge cable and have both sides connected over USB then I do see the lighting bolt next to the figure for the left side (90)

Worth a ticket being created?

How do you charge the left half? Via left usb or via bridge cable?

In the morning, was there 76% with percent sign or lightning bolt sign?

Anyway, the problem is just visual - it relates to how we determine what voltage 100 should be and resetting the value when the charger reports fully charged.

Battery 100% reset when charger reports fully charged. · Issue #1283 · UltimateHackingKeyboard/firmware · GitHub

Usually bridge cable, but that stops at 70%
USB yesterday got it to 97% over night but not to 100%.

Alright, that is a bit strange. I will add some debug features and ask you to report voltages. Or you can try to get them from the zephyr log in agents advanced settings - it should log voltages every minute or so.

I am interested in the voltage when the battery stops charging.

I am away from computer till next week, so feel free to bump me if i forget about it.

Not sure if this helps…

Showing 86% and 96% with no lightning icon.

These voltages look like fully charged batteries.

I will look into it, but it probably is an easthetics-only issue.

Some slight changes today…

Would you please test the artifact from Max charge behavior · UltimateHackingKeyboard/firmware@37c6065 · GitHub ?

You can also use the statsBattery command, which will show right half’s battery info on the oled display. (It yields slightly different numbers, as they are provided without some of the postprocessing calculations.)

Firmware installed now and will monitor.

Interesting it now says 100% 100% :slight_smile:
