Nexus 7 2013 Wi-Fi (razor/flo) about batterychargelimit HOT 10 OPEN

I have this file on my flo here which has 0 before and 1 while being plugged in.

/sys/class/power_supply/ac/online

I'm on Paranoid Android 6.0.3.

@klausmcm thank you for investigation, I'll check it as soon as I have an access to my tablet. For now, can you please check whether this file has a write permission?

from batterychargelimit.

@klausmcm, Bad luck. It's read-only

127|root@flo:/sys/class/power_supply/ac # ls -l
lrwxrwxrwx root     root              2017-10-20 20:53 device -> ../../../0-0055

My Moto X 2013 (ghost) also has the pm8921 and pm8921_charger control file (ie. /sys/module/pm8921_charger/parameters/disabled) works for me. Did you try it? What's the console output for this:
ls -l /sys/module/pm*/parameters/

from batterychargelimit.

@Himura2la I have the same issue. However, I also had this issue #46 on my Nexus 5. The app selects the correct control file on my Nexus 5 but the file is also only readable. I did chmod 644 /sys/class/power_supply/ac/charging_enabled and the app works fine now. I believe the same would work for the Nexus 7.

@sm4rk0 this is the output for me

root@flo:/ # ls -l /sys/module/pm*/parameters/
/sys/module/pm8xxx_regulator/parameters/:
total 0
-rw-------    1 root     root          4096 Oct 20 17:21 debug_mask

/sys/module/pm_8x60/parameters/:
total 0
-rw-rw-r--    1 root     root          4096 Oct 20 17:21 debug_mask
-rw-rw-r--    1 root     root          4096 Oct 20 17:21 sleep_time_override

from batterychargelimit.

@klausmcm adding a write permission may be a good decision for files that are obviously do switch the charger. online looks more like an informative output... But the idea of @sm4rk0 looks great, I'tt check it soon

@klausmcm Hi! I have a Nexus 7, and I observed the exact same thing as you mentioned on Oct 19th. However when I try to change the file's content fron 1 to 0, the device just restarts itself, did that happen to you also?

from batterychargelimit.

I have a Nexus 7 flo (2013 WiFi). Can't get this app to work, which is a really pity as I wanted to leave the device on permanent wireless charge as I'm using it as a replacement for a Sonos CR100 controller, which Sonos are about to kill-off.

I'm running lineageos 14.1 (Android 7.1.2).

This is the output for root@flo:/ # ls -l /sys/module/pm*/parameters/

/sys/module/pm8xxx_regulator/parameters/:
total 0
-rw-------    1 root     root          4096 Oct 20 17:21 debug_mask

/sys/module/pm_8x60/parameters/:
total 0
-rw-rw-r--    1 root     root          4096 Oct 20 17:21 debug_mask
-rw-rw-r--    1 root     root          4096 Oct 20 17:21 sleep_time_override

So nothing obvious...
Anybody have any other suggestions? I'm happy to try/evaluate anything.

@dh29 I had the exact same problem, there is an XDA thread that you could check to see what you can do to help. Basically they need to know where the 'control file' is in Nexus 7, so that they can do something about it

I tried to use the /sys/class/power_supply/battery/charge_now and my Nexys 7 rebooted. Did you manage to find a solution to this problem?
