I have found control file for pixel 5a /sys/class/power_supply/sm7250_bms/charge_disable. You can install termux apk and run command
su echo 80 > /sys/class/power_supply/sm7250_bms/charge_disable
It does same thing. I've tried with command and it's works well.
What are the enable/disable values? 0/1?

Are you

No, you don't have to turn off adaptive charging. What phone are you using?Are you rooted? Install root explorer and see if you have actual file in the path.
Pixel 5a. Its brand new. Its rooted. That file is in there and the file doesn't have any 0 or 1 values in it.

It says null (ignoring). Then it says, "cat: /sys/class/power_supply/sm7250_bms: is a directory.

This is an unlocked phone that I bought from the Google outlet.

I have exact same unlocked phone bought right from Google but mine has Pixel experience Rom with custom kernel (I don't know if that matter). Values of that file can be only changed from Battery Charge Limit app. It should work after you set right control file. I took a screenshots with my settings.

Working on a project with an old android. This device will stay plugged in and have the screen on 24/7.

Does anyone have recommendations for what numbers I should set for "limit charging" and "recharge below"?

Anyone got a problem with battery stats after using this app for years?
I use OnePlus 6T and it stays at 1% for more than two hours now. The phone basically never shows me how charged it is and the battery always has much more juice remaining than what shows up on the screen. Suggestions?

Go with limit charging as 80 , recharge below 25

IMO this is bad advice. I personally would recommend charging between 60-70%. The battery really shouldn't be dipping below 40% to start with, and then you should consider that your battery will degrade eventually and start shutting off on its own, usually around 50% charge. 60-70% will give you the best longevity for 24/7 use. 40-50% will give the best longevity overall, but you will need to increase this to 60-70%, or higher, at a later date once the battery degrades.

    Please read the following before installing the app:
    • This app requires a rooted mobile (Android 4.0 or later)
    • Before uninstalling the app, disable limit in the app (if forgotten, reboot after uninstalling)

    Usage instructions and app details:
    • Enable limit in the app
    • Change the limit up to which it should charge (default: 80)
    • Check which control file suits best for your device, see Q/A section below for hints. In most cases, the pre-selected choice should be the best that's available for your device.
    • The app only gets kicked in while you connect a charger (or USB), and automatically closes shortly after unplugging charger (or USB) i.e it only runs in the background as long as it is plugged in, and won't affect your battery life.
    • If your device is not charging even after disabling the limit (which shouldn't happen, just in case), uninstall the app and reboot the device (The changes made by the app don't survive a reboot). Your device should charge normally then.

    If the app says "your device is not yet supported"
    There are various control files in different devices (due to OEMs), and toggling the values in them (0 and 1) makes it possible to enable and disable charging via software (might not be possible for every device), though the charging cable is still physically connected.
    Since we cannot own every device, it is impossible for us to find every file. We can support a lot more devices with information provided by testing possible files on different devices by you, the people in the community.
    Hence, for support to be provided to other devices, you need to do some detective work to find the files on the respective devices. Please refer to this file for control files of currently supported devices, so you can know where they are generally present: https://github.com/sriharshaarangi/BatteryChargeLimit/blob/master/app/src/main/res/raw/control_files.json
    You can send us a pull request or open an issue on GitHub. If necessary, you can also post the name of the device and the file here.

    FAQ
    Q) Can you please add support for... (insert arbitrary device name here)?
    A) Maybe, but we need your help. Bottom line, this app does nothing but modifying the content of a certain "control file", some more details are given above. If you find such a control file for your device, please let us know (ideally, open a GitHub issue here: https://github.com/sriharshaarangi/BatteryChargeLimit/issues) and we will add support for your device.

    Q) I think I observed a bug. Can you fix it?
    A) We'll do our best, but we need your help: Please open an issue on GitHub (https://github.com/sriharshaarangi/BatteryChargeLimit/issues) and provide as much information as possible about the problem.
    In most cases, we need the "logcat" logs of your device to find out about the exact issue. In order to provide those, you could use aLogcat (https://play.google.com/store/apps/details?id=rs.pedjaapps.alogcatroot.app).
    FOR CHARGING-RELATED ISSUES: Select the "Time" format in the preferences of aLogcat, so we can see precise timings, and filter for "(Charging|Power) State" with "Apply as regular expression" ticked.
    FOR CRASHES: Please also select the "Time" format and provide unfiltered logcat data that includes the stack trace of the crash.

    Q) Why do you want to limit charge to a lower capacity?
    A) In short, to prolong battery life in long term usage. For more information, refer this : http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

    Q) How does this app work? Does it modify something in the ROM/Kernel to stop charging?
    A) It writes "0" or "1" to a control file that represents some state of the power supply hardware, as simple as that. The file is normally read-only, so you need root to overwrite it.
    The change might be automatically reversed by the OS if the power supply situation changes. Anyway, it should never survive a reboot of the device.

    Q) I can select multiple more than one control file in the radio group. Which one should I use?
    A) For most devices, battery_charging_enabled or store_mode are preferable. Try those first and see if it works. If you observe any bugs, try another file.

    Q) I have a OnePlus device, and the app doesn't work correctly for me. What to do?
    A) Check that the control file you selected is NOT battery_charging_enabled! Although it should be preferred in general, there are known issues for this file with OnePlus devices.

    Q) I use the store_mode on a Samsung device. My device always stops charging at 70 % (or other specific percentage), no matter what limit I have set.
    A) The store_mode implementation differs among the supported (Samsung) devices.
    Normally, it freezes the level at the current percentage when store_mode is triggered until the cable is unplugged for some seconds. This is a normal condition due to Samsung's kernel implementation, it's not a bug of this app.
    If this is a problem for you, try to switch to another control file (e.g. batt_slate_mode), if supported.

    Q) How does the "automatic stats reset" work?
    A) The automatic reset should perform a stats reset when your power supply is removed while the battery level is within the desired range. Everything else is wrong behavior.

    Q) No matter if I the "automatic stats reset" is enabled or not, my phone is always resetting my battery statistics. Why?
    A) Are you using a threshold above 90%? If yes, your ROM will most likely clear the stats when the power is removed. There is nothing we can do about that.

    Announcement: Official Version 1.1.0, welcome @xdnax!

    Hello everybody,

    it has been quite a while since I wrote my last post here. The reason for this is rather simple:
    Apart from being very busy in the last months, I realized some time ago that I was investing more time in reading and answering posts in this thread than doing actual implementation work for BCL, which is definitely not my intended workflow.
    Therefore, I shifted my attention completely to GitHub, where the workflow was/is much more efficient.
    Some people here suggested to officially fork this project and continue it elsewhere. I want to say the following to those people:
    While it is in general a good thing that dead projects are forked and continued, good behavior demands to first open a GitHub issue asking whether the project is to be continued before suggesting an official fork, which did afaik not happen.
    Furthermore, a simple look at GitHub would have clearly revealed at all times that I was reacting to issues there on a regular basis, so our project was hardly inactive, and surely not dead!
    Luckily, @xdnax was considerate and smart enough to keep mentioning that he wants to respect our work and keep his fork unofficial for the moment, which deserves a huge THANK YOU from my side!

    Talking about @xdnax:
    He did a great job in contributing to the development of this app during the last months.
    Unfortunately, I didn't have his contributions on my radar for quite a while.
    Since we love to work with other motivated and decent developers like him, we are happy to announce that he is now the third "official developmer" of BCL.
    Welcome to the team, @xdnax!

    Some people noticed the appearance of a semi-official version 1.0.5.
    Although I never had time to publish an official build, I indeed created this version and uploaded it with a "v1.0.5" tag to our GitHub repo.
    This is where the F-Droid build system picked it up and created an APK from it, which I myself wasn't aware of for some while. Sorry for the confusion guys...

    During the last days, we organized our internal communication and unified our contributions to bring out a new official version.
    Well, here we go: I'm happy to announce that we finally release version 1.1.0!
    Link: https://www.androidfilehost.com/?fid=817906626617956614
    Please don't get confused about the numbering: This release includes all improvements of @xdnax and more, and is not a major version step because it doesn't introduce any breaking behavior changes.
    Happy charging, opening post will be updated soon!

    • UI & icon redesign @xdnax
