[Q] offline charging leds

How do you enable offline charging leds...nothing lights up when charging with phone off. Charging status can be checked by depressing power button when charging, but no led lights. Currently running [ROM][KERNEL][4.4.2/4.3] Quantum v3.21 & QuantumKernel 1/16 on galaxy s3 i747 d2att. Have tried enabling different settings in display & lights...battery options etc. Is this possibly a kernel feature that needs to be addressed? Thanks

I think turning on kernel would mean turning on the phone - CPU and all. If I am not wrong, battery charging circuit is the one that kicks in when the phone is switched off and charging applied. I see this happening independent of phone processes when phone is off.

Would that mean the feature is controlled by the rom? Charging leds seem to work properly if phone is being charged while on. I can restore to Hyperdrive 4.1.2, which I have on nandroid in which the charging leds work properly. The Quantum 4.4.2 is based on the CM11 nightly rom...I've seen nothing in that forum about this. I'm limited to where I can ask about this because of posting rules. Thanks for responding.

Yes. That's what I feel. I feel the LED is controlled by phone software, wherin the battery level you see is controlled by charging circuit that should be separate from phone software.

OK, thanks for helping with the explanation...guess I'll just have to hope some future update fixes this feature. It's not a deal killer with the rom, just inconvenient when charging with phone off.

From what I have observed thus far, charging battery with phone off gets routed via a separate circuitry, without activating any of phone functions. This enables battery to get charged faster too. Not sure if anyone would alter a functionality this core level.

To Be sure in what I am saying, I just restored my Hyperdrive backup, & charging led works fine with phone off. CM nightly also has no charging lights...maybe just something left out of the mod or a hidden setting. Maybe someone else will address this in the Quantum Rom section. Thanks again for spending your time on this!!

Oh. Now that's new to me. Maybe I missed something. Sorry.

I don't have this issue. Are you using a battery stats app like AccuBattery that's trying to warn you about over-charging? AccuBattery will chirp at me if I go over 80% (and I think every percent after) unless I turn that feature off.

Question Limit Battery Charge

On my OnePlus 7 Pro I used the battery charge limit app to limit my battery charging to 85% for battery health since I was going to keep it awhile (2 years). Anyways, the same app doesn't work on the OP9 Pro and I tried Advanced Charging Controller Magisk module and that didn't work either. Looking for ideas if anyone knows of something else to try. Since this phone charges so darn quick, it's even less of an issue to limit the battery max percentage and the ideal phone to do such a thing.

I'm on the latest stable. I may try that.

Try a non warp/dash/whatever cable/brick with ACC

Same problem with Acca, will try the Battery Charge Limiter from Play Store

I've just been using AccuBattery which notifies me when charge reaches the level I set (I use 90%) and unplug it when it alerts me. That won't help if you charge it at night, but for daytime charging the phone is usually plugged in right next to me.

Just installed latest Magisk Canary and ACC module with ACCA app doesn't stop the charging on any charger I've tried. Anything else you did?

solved the problem physically. I use a smart plug with an auto stop timer, not the best solution but it gets the job done mostly.

How would you get it to stop at a specific percent though? If there's some sort of timer to stop at a detected voltage, that could work.

nah, i simply set it to a set timer, for me that is 25 minutes.
As you are saying this, it makes me think that it is not hard to do a script to do this automatically. . too much work for this tho, but totally doable with samsung smartthings.

It probably wouldn't be too difficult, but since we already have some apps and Magisk modules to do this, which worked great on my OP7 Pro, I'd like to get it working like Burt Squirtz said he was able to do. I'm just annoyed that I can't get it to work on my OP9 Pro.

After having tried both AccA and the Battery Charge Limit, unfortunately I must say that none worked for me. I miss do much the smart charging feature from pixel-inspired ROMs I used on my Xiaomi phone.
I appreciate the attempts mentioned above, but does anyone have a working method to automatically stop charging at 80%?

Definitely following this for that as well. What's good is that OnePlus has an option in the settings to do adaptive charging. I've already had it learn my wake up time and it will not start charging the battery until a little before I wake up. I get a little notification that my phone will not continue charging until a specific time. Very neat!

how did this happen for you, and do you mean optimized charging in batt settings? I think it is because I charge my phone at random times that it does not do anything at the moment

That is correct. It's Optimized Charging.

Has anyone managed to get on top of this in the meantime? Myself, I'm using the Accubattery's sound alert, but I'd love to stop charging automatically when it reaches the limit.

I think, I fond the reason, but no solution.
I am using all time Tasker to control charging limit. I's doing the same way like Battery Charge Limit and AccA: By copying the file "charging_enabled" into /sys/class/power_supply/battery/ .This was working until OP8pro. Unfortunately, all this apps suddenly have no writing access to this directory. Not even on rootet device.
So if anyone have idea, to make /sys/class/power_supply/battery/ writeable again, please tell.

A temporary workaround for Tasker users is to create a repeating notification once the battery reaches a certain limit. That's what I've done and it does the job for the meantime!

Use /sys/class/oplus_chg/usb/chg_enable, 1, 0 as the config file.

Question Automatic shutdown according to battery percentage app or Magisk module.

As the title says, is there any app or Magisk module that can automatically shutdown your device according to battery percentage?

ahhh we have almost the same issue but my issue is whenever my battery percentage reach 20% wifi get disconnected i need to to setting and wifi and click scan again for it to get reconnected i think it is some sort of battery saver
i hate it whenever i'm playing it disconnect me

Actually, I'm not asking about an issue.
I'm asking if anyone knows of an app or module for Magisk that can shutdown the device accordingly to battery percentage.
I'd really like to set my phone to shutdown when the battery hits 15%.

I do at 20% although 30% or higher be better.
After 20% there's a lot less usable power available and charging from that low is more stressful on a Li especially if fast charging.

I'll do 20% shutdown and 90% battery charging stop.
That's 70% usable power, I can't do anything better than that.

I generally do 40 - 70% or so. On my device it's 3 hrs on SOT and take 15 minutes to fast charge.
Li's like frequent midrange power cycling; use it if it fits your needs.

Magisk module : Advanced Charging Controller (acc)
https://forum.xda-developers.com/t/advanced-charging-controller-acc.3668427/
It has features as:
Shutdown at set percentage, eg. 20%
Stop charging when reach a percentage, eg. 75%
Cool down charging, so the device and battery won't be very hot using temperature detect on battery.
Charging voltage/current limitation.
Charge cool down as set, eg. 50 seconds charge and 10 seconds cool down without charging, then repeat.
Read the README in github.
ACC app has some issues. Module is working better and updated.
The module will need you to manually edit the settings profile, and you need to use command line.
If you just want to stop charging at certain percentage, Battery Charge Limit is enough.

Both need root.

I use Battery Charge Limit already on my Mi Pad 4.
Advanced Charging Controller seems to have a lot more features.

I haven't been able to get ACC with ACCA (GUI) or Battery Charge Limit to work on the Poco F3 with Xiaomi.EU rom and root.
None of the control files work on both apps.

AccA is faulty.
Use the Magisk module.
You might want to ask cutsom ROM developers because they had managed to get smart charge working, so there's definitely control file that works.

I got Acc with AccA working!
I was testing the charging switches without plugging in the charger, my bads...
Some how Battery Charge Limit does not work, it's a simpler app and I used it with my Mi Pad 4 so I thought it would just work with the Poco F3.

Check ACC control config what control file your phone uses, then see in Battery Charge Limit if you can select that control file manually.
I think it can also manually write the control file, but not quite sure.

Yeah I figured that, but since I have Acc with AccA working there's really no need to go back to Battery Charge Limit.

You mean ACC with AccA is working properly? If not, is there any problems with using ACC with AccA app?

Themes / Apps / Mods [MOD/magisk/root] Set charging limit to 80/85/90/95% v2

After some readings on: https://forum.xda-developers.com/t/limit-charge.4355851/
and https://forum.xda-developers.com/t/mod-magisk-root-set-charging-limit-to-90.4363477/
( Credits to @rickysidhu_ and @foobar66 )
There is a thing I found and tested:
"charge_stop_level" must be used together with "charge_start_level"
Spoiler: Details
If set start @40 / stop @60, the phone will begin charging when (and only when) the battery drops to 40%, and stops charging @ 60%.
(it defines a range, and the first time the user hit the range boundary activates this range function)
If set stop @90 without setting a start, the phone will refuse the 2nd time charging until the battery drops to default 0 (or the battery service/phone has been restarted)
(This explained many "phone not charging" reports in the above links posts)
I like @foobar66's magisk mod solution. It is simple and safe.
It has only 1 line of working script in the zip.
So I "clone" it with some different values (added the fix, so 2 lines of script code in each zip now, that's all it does)
These are for the lazy people who don't want to deal with advanced settings, and who want a 10-second trouble-free simple solution for battery health.
The 4 clones:
P6n_charginglimit_95.zip (charging limit to 95%, it should give you an extra ~30% battery life span in lab-tested theory)
P6n_charginglimit_90.zip (charging to 90%, an extra ~60% battery life span)
P6n_charginglimit_85.zip (charging to 85%, double the battery life span, recommended for joe and johns)
P6n_charginglimit_80.zip (charging to 80%, should give more than double the battery life span)
Those numbers are the best estimates from other battery research papers, no guarantee.
To install, pick the one you want and flash it in Magisk.
To uninstall, simply disable or remove it in Magisk.
A12.1 tested. It should work on A13.
Edit: A13 is also confirmed working.
Reply problems if you find any.

I use advanced charging controller, I stop charging at 81% and I can regulate voltage as well. Temperature triggers etc it's great.

How does it increase battery life by 30%?
Or you mean battery health ?

I use ACC plus Tasker to keep the battery entering idle mode at around 50% while plugged. I got my pixel 6 last November, now the battery gets 82 cycles so far.

The thing is, ACC monitors/controls too many components in the system that I don't fully get, and I am not sure if it conflicts with built-in "smart charging" or other circuit controllers or not, and have to combine a Magisk backend module and a root-access frontend APP to make it work with so many details settings to setup....... It is just......too heavy?
(or I am too old to tinkering those things.....my sad middle-age life)
These .zips are the "10-second solution" for lazy folks.
It does only 1 thing, It is transparent and super snappy (only 2 lines of script, no binary), and it can hardly go wrong.....it just works.

It doesn't interfere with the built in stuff and you don't need magisk module anymore. It takes 20.9mb on system so it's not heavy, I also like being able to adjust on the fly (have it set to 70% for long home use and 85% for out and about)

So when I setup acc stopping at 80% on Android 13 and its place on pixel stand 2, the charging oscillates on/off. It would charge for few minutes then stop and charge for few mins and stop. Are you experiencing this? This behavior did not occur with Android 12

I strongly agree, just not worth having to deal with acc, getting idle mode to work, debugging, getting it to work again and hoping it still works. If I get the time to do so might write a module that integrates a slider in settings or as a quick setting to set to what percentage it should charge and executing those lines of code with that percentage.
