Xiaomi POCO X3 NFC (surya)
focal 20.04 devel (r581)
France, SFR

VoLTE tests : https://codeberg.org/EricHeintzmann/UbuntuTouch/issues/23

@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.

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

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

@paulcarroty
Reinstalled.
Does not work on surya.

Test 2 (with udev rules) : same results as test 1

I applied udev rules from README :

phablet@ubuntu-phablet:~$ ls -al /sys/class/power_supply/battery/{battery_,}charging_enabled
-rw-rw-r-- 1 phablet system 4096 févr. 17 17:28 /sys/class/power_supply/battery/battery_charging_enabled
-rw-rw-r-- 1 phablet system 4096 févr. 17 17:06 /sys/class/power_supply/battery/charging_enabled

• when charge is less than 85%, device charges :

  tail /sys/class/power_supply/battery/{battery_,}charging_enabled
  ==> /sys/class/power_supply/battery/battery_charging_enabled <==
  1
  
  ==> /sys/class/power_supply/battery/charging_enabled <==
  1
  

• when charge is more than 85%, device doesn't charge (and doesn't seem to discharge until unplugged) :

  tail /sys/class/power_supply/battery/{battery_,}charging_enabled
  ==> /sys/class/power_supply/battery/battery_charging_enabled <==
  0
  
  ==> /sys/class/power_supply/battery/charging_enabled <==
  1
  

(when unplugging, the values in the two files return to 1)

@paulcarroty said in Resurrection of Indicator Upower:

I need beta testers to check the limiting battery's charge.

Test 1:

• when charge is less than 85%, device charges :

  tail /sys/class/power_supply/battery/{battery_,}charging_enabled
  ==> /sys/class/power_supply/battery/battery_charging_enabled <==
  1
  
  ==> /sys/class/power_supply/battery/charging_enabled <==
  1
  

• when charge is more than 85%, device doesn't charge (and doesn't seem to discharge until unplugged)

  tail /sys/class/power_supply/battery/{battery_,}charging_enabled
  ==> /sys/class/power_supply/battery/battery_charging_enabled <==
  0
  
  ==> /sys/class/power_supply/battery/charging_enabled <==
  1
  

  (when unplugging, the values in the two files return to 1)

@paulcarroty said in Resurrection of Indicator Upower:

Ahoy, there's battery_charging_enabled support in the latest builds and I need beta testers to check the limiting battery's charge.

You need to apply new udev rule from README and install the latest build from Github Actions.

Thanks !
I installed latest build from Github Actions.

Notice that, on surya, default permissions are :

• -rwxrwxrwx 1 system system 4096 févr. 17 11:15 battery_charging_enabled
• -rw-r--r-- 1 system system 4096 févr. 17 11:15 charging_enabled

I leave them untouched for the first tests
Let me know if you need tests with different permissions

@paulcarroty
A merge request has been proposed on surya, but another (global) solution is suggested in the comments :
https://gitlab.com/ubports/porting/community-ports/android10/xiaomi-poco-x3/xiaomi-surya/-/merge_requests/20

@paulcarroty
According to https://android.stackexchange.com/questions/200032/difference-between-system-files-charging-enabled-vs-battery-charging-enabled battery-charging-enabled has a different behavior than charging-enabled.
So I will just make a MR to add the above udev rule in surya and karna.
Thanks for your work

@paulcarroty
The udev rule is working properly:
-rw-rw-r-- 1 phablet system 4096 janv. 23 09:08 /sys/class/power_supply/battery/charging_enabled
And the content of charging_enabled goes well from 1 to 0 when the charge exceeds 85%.

But, despite this, the device continues to charge beyond 85 % !

(I believe that, on surya and karna, we must have to write in another file.
I will try with `/sys/class/power_supply/battery/battery_charging_enabled )

@nonobike
It should work !
Please, take a look a these issues and their solutions.
https://github.com/fredldotme/snapz0r/issues

@paulcarroty
I think it's indeed the right approach.
I will confirm today that it works.

@nonobike
Indeed.
If you want to check on your phone you can type in terminal.app :

zgrep -i squashfs /proc/config.gz

@nonobike

in OnePlus Nord N100 kernel config, the following lines are already present :
CONFIG_SQUASHFS=y
CONFIG_SQUASHFS_XZ=y
CONFIG_SQUASHFS_LZO=y

@paulcarroty
I tested the 0.5 release on surya and I can confirm that it works as expected.

Regarding the udev rule, it works perfectly with permissions 0666.
But if I try 0664, it no longer works…
What is the group of the /sys/class/power_supply/battery/charging_enabled file on other devices?

@paulcarroty
Ok.
Thanks for your work.

@paulcarroty
I can see on github that v0.5 has been released.
But only v0.4 seems to be available on the open store.
