1. The app works when the device is plugged in and starts charging below the max threshold and will stop once the device is either unplugged or hits the max threshold, completely stopping charging!
2. NOTE: This app requires ROOT access to work - if you don't know what it is, it is highly probable that your device doesn't have it.
3. If your device is not supported, please follow the help & support text below.
4. To request support for a device/issue, please open an Issue on GitHub and a developer will assist you soon!
5. Also, checkout xda-developers. com for more information on rooting devices.
6. There is no other way this app can work on non-rooted phones.
7. Not all devices may be supported as well!
8. This app is not responsible for unintended behavior - though any changes done by it are usually temporary and typically do not survive a reboot.
1. I suspect the phone's power saving may be constantly attempting to disable the app, allowing tiny bursts of charging past the limit.I like how it allows my phone to stop charging when it reach max capacity.
2. I had to set the CTRL file to /sys/class/power_supply/dc-wireless/charging_enabled to get it working for wireless charging but not for wired.
3. That file works for me for both wired and wireless charging, so I suggest that people try that one first.
4. Small issue, when I leave the phone charging overnight, it does creep past my set 80% limit - very slowly (about 2% per hour).
5. A couple of suggestions for the developer are that it'd be nice if more of these possible CTRL files were predefined in the app and if there were a Browse button so that we could select the file instead of typing out the path.
6. The app worked for wired charging out of the box for me, but not for wireless charging.
7. Now I still keep my phones plugged but the app makes the job on preserving my batteries! Thank you to the developer for this great app!Nice but some bugs noticed.
8. After that it worked correctly (default setting worked, but it never started charging again after first disable).
9. However, if I set a limit to 75%, it would stop charging, but then it would tickle it's way back to 100%.
10. Even typing this, it is plugged in and charging beyond the set limit.
11. Edit: I've found an even better CTRL file to use on my device (an LG V30 running a custom ROM): /sys/devices/platform/lge-unified-nodes/charging_enable (note no 'd' on the end of this one).
