Resurrection of Indicator Upower

About this error :
ValueError: could not convert string to float: '3,65353'

Maybe it is a localization error (french) : there is a comma instead of a point

@Eric-H yeah, upower depends on current locale. Fixed by enforcing

@paulcarroty
Reinstalled. It seems to work fine.
Do you need specific tests ?

paulcarroty

@Eric-H test fast charging if you have the hardware for.

Eric H

@paulcarroty
Sorry, I couldn't do the test before today...

So I used the Xiaomi charger supplied with the phone (which fully charges in less than half an hour) with the latest version (0.7) of uPower, but it seems that fast charging is not detected and there's nothing related in the logs.

Eric-H Attach the power.txt file when the battery is being charged and has less than 50% capacity.

I tried to generate the power.txt file but there is an error on stderr :

cat: '/sys/devices/platform/soc/c440000.qcom,spmi/spmi-0/spmi0-00/c440000.qcom,spmi:qcom,pm6150@0:qcom,qpnp-smb5/power_supply/main/health': Invalid argument

The health files exists and is world readable :

The error persists even if I try to

add simple quotes
replace cat with tail

@paulcarroty
For some unknown reason, today the message on stderr did not appear.

So here is the power.txt file for surya attached.

I can see POWER_SUPPLY_CHARGE_TYPE=Fast in udev battery info, so it seems to be a fast charge.
What should Indicator Upower display ?

No, I got Fast with low-end 7W charger too. My guess it's POWER_SUPPLY_FASTCHARGE_MODE=1. My device has POWER_SUPPLY_HI_POWER.

How much power can your charger deliver? POWER_SUPPLY_POWER_NOW=39764516 looks realistic for 45W.

I also tried to find the Fast Charging voltage (9..12V) on BMS and failed, so you can try it too. Probably not being monitored by software. And all of this is very device-specific.

The Indicator Upower now supports battery charging limit on MTK and other devices - don't forget to reinstall indicator if this feature didn't work in older releases.
