Advanced Charging Controller (acc)

[nostromo12]

ok, VR25 lets do: switched to automatic mode and executed auto loadswitch test. One was found.
Now charge stops at desired limit, but charging symbol in device top line is still active, also infotext: device is charging.
But % indication is rapidly decreasing! 2% in a few minutes! power supply still connected.
acca shows actual current changing between 2 an 4A !!!! Should be negative and 0,1A !
Could I harm the pitiful battery?

Thanks for the update; acc is now working again for my Pixel 4a 5G.

Manually select another working switch (with acc -ss) from the output of acc -t.
Refer to troubleshooting > charging switch.

New approach with Pixel5:
acc -t shoes the switch sm7250_bms/charge_disable 0 1 working
I set this switch with acc -s s="sm7250_bms/charge_disable 0 1"
But result is the same : load stop at 80%, but then high discharge with power attached
wrong command? Little experience with shell commands :-(

My phone is making charge plugin sounds often enough.
Infinix Note 2, Resurrection Remix Nougat 7.1.2 default kernel. ACCA always crashes very time I set a charging value, tried ACCA and Magisk module none is very persistent with the value I set.

@VR25 I see you included hiz_mode charhing switch. Did you get any more info about it?

Hi all! Im trying to use advanced charging controller on my xiaomi a2 lite with lineageos 17.1 and visually it does itss thing (except the battety icon remains with the charging icon) I set the max to 80% and it stops there, but somehow its hard to belive that it doesnt loose 1 % overnight. How can i check of it keeps charging or not? If thats the case what should i change in order to make it work?

Thanks for the help in advance!

Im having trouble getting this to work on my OnePlus 9. Its worked find on my OP5/6/7/8 but on this 9, its having trouble.
At first ACC Daemon would run, but no charge stopping on wireless charger.
Now after updating to latest app and ACC version, the Daemon wont stay running and I keep seeing an error on acc -t

:/data/data/com.termux/files/home # acc -t

:/data/data/com.termux/files/home # acc -t

(!) Charger must be plugged to continue...
(i) Alright, this may take a minute or so...

(!) [/sys/devices/platform/soc/ socplus,chg_intf /oplus_chg/battery/mmi_charging_enable 1 0] won't work

Good evening.
We have an old Samsung Galaxy S2 GT-i9100, which we are converting to an advanced gps tracker.
However, we have tried everything to look for a file to toggle/switch the charging.
The phone runs the PhilZ kernel with stock android JB, and is rooted.

The files we find under /sys/devices/platform/sec-battery/power_supply/battery are:
batt_current_adc batt_temp_adc_spec current_avg status
batt_current_now batt_temp_check device subsystem
batt_full_check batt_test_value fg_psoc system_rev
batt_lp_charging batt_tmu_status health technology
batt_lpm_state batt_type mp3 temp
batt_soc batt_vfocv online type
batt_temp batt_vol power uevent
batt_temp_adc capacity present video
batt_temp_adc_avg charging_source siop_activated voltage_now

We have tried toggling the lot, resulting in a lot of reboots. The only file to actually stop charging is the "Online" file. But this can only be used to stop charging, not re-enable it. When we try that, the phone reboots.
The chip responsible for the charging (MAX8922) does have a disable function, which is also implemented in the driver code. But we can's seem to find how to switch this from user space.
Does anyone have a clue?
Cheers!

Hi. I have a similar vintage Note I GT-N7000 which is running NightOwl Lineage. Did you ever find an answer?

Installed ACC 1.9.5 on my Pixel 5.
But still high discharge current, when charge limit is reached. ACCA now recognizes load switch sm7250. Thats new! Keep on track guys!

Hello. Here is another question. I went looking at the online file as you mention above. I can cat its contents and it seems that 0 is not connected at all, 1 is connected usb, and 3 is connected AC. Is this consistent with your findings? I note the file has permissions all read-only. How did you go about stopping charging with this file? To write to it would require a chmod as it is all read-only. And what did you write to it? Thanks

this works perfectly on wall chargers but if i use it plugged into my car the daemon stops running and i have to restart it manually. when its plugged into my car it starts android auto. is this normal?

Maybe bypass charging is working in which case battery charge level won't drop. It works in my Poco F1 (voltage limiting based) and older Redmi devices. I keep Redmi 3s plugged in all the time to minimise stress on the battery and the battery charge doesn't budge for days at a time. You can use 3c Battery Manager to keep track of battery current, voltage, temps. etc in the background.

Is it the only working switch?
Keep in mind that this is a kernel issue.
I can only do so much to mitigate it.
The actual fix must come from upstream.
Try acc -s s=3700
This instructs acc to use voltage control files to stop charging.

MediaTek devices are problematic by design.
Upgrade acc and try the following:
acc -t /proc/mtk_battery_cmd/current_cmd 0::0 0::1
If the switch works, set:
acc -s s="/proc/mtk_battery_cmd/current_cmd 0::0 0::1"

I still have no information.

As long as charging stops (i.e., battery level stops rising), you can ignore charging indicators.
Those are the result of flawed design by OEMs themselves.
If the battery holds its charge overnight, it's operating in idle mode.
Refer to the doc for details.

Wireless charging control support is not as common (kernel issue).
Refer to documentation > troubleshooting > charging switch.

Install the latest acc and share the log archive generated by acc -le.

online is a status file.
It cannot be used to [reliably] control charging.
acc -p prints a list of potential charging switches that you can test with acc -t <line> and set set with acc -s s="<line>".
