Battery-Health-Charging

Battery Health Charging extension for GNOME shell

Battery Health Charging extension sets the limit of battery charging to maximize battery health mainly for laptops that support these features. Since users usually keep their AC adapter connected while using their laptop, the battery is often in a state of high-power (98-100%) for an extended length of time which causes a reduction in battery life. Initially, I made this for my laptop (Asus) but as of Version 4 , the extension evolve to support several brands. Some laptops have fixed threshold, while some laptop's threshold can be customized. (See details in laptop supported). This extension detects the hardware and displays the option accordingly.

1. Full Capacity Mode: Battery is charged to its full capacity for longer use on battery power.(Threshold are customizable on some laptop.)

2. Balanced Mode: Stops charging when power is above 80% and resumes charging when power is below 75%. This mode is recommended when using the Notebook on battery power during meetings or conferences. (Threshold are customizable on some laptop. Some laptop don't feature this option.)

3. Maximum Lifespan Mode: Stops charging when power is above 60% and resumes charging when power is below 55%. This mode is recommended when the Notebook is always powered by AC adapter.(Threshold are customizable on some laptop. Some laptop the maximum lifespan mode is set to 80%)

Features

  • Conflicts with other battery charging threshold controls apps / extensions / local workarounds scripts, so better to disable or remove before using this extension.

  • The charging mode persists on reboot. As of Version 4 if your device needs privileged access (root) to change the threshold, this extension will prompt you to install polkit script. This way the extension can change the threshold on users input and also restore it on system restarts.

  • Customize threshold (only for device that support custom threshold)

  • Extension Pref icon in quick settings menu. And added option in preference to remove this icon from quick setting.

  • Option to choose 3 set of icons in preference.

  • Shows an icon indicating current mode. And added option in preference to change index and also to disable showing icon

  • Option to change behavior of systems battery indicator. When charging threshold is set and battery level reaches threshold, the default behavior in gnome is system battery indicator will display On battery - charger unplugged/powered-off icon and there is no way of knowing if charger is plugged and powered. Upon enabling this option, system battery indicator will display charging icon. Note: If this feature is not working for your laptop, kindly raise an issue with your and post the results of power supply name with the following command in terminal ls -l /sys/class/power_supply

  • Displays notification when threshold/mode is changed. And added option in preference to disable notification update

  • Display current mode subtitles in quicksetting toggle (Gnome 44 and above). And added an option in preference to remove this subtitle.

Changelog

Version 21

May 22, 2023

  • German translation update (Thanks olebole)
  • Fix for some thinkpad mode conditions where start threshold should be less than end threshold. (Thanks olebole)
  • Adjusted allowed custom valueLegacy thinkpad (tpsmapi) as allowed values for end endthreshold > startthreshold + 5

Version 20

May 18, 2023

  • Turkish translation update (Thanks sabriunal)
  • Used CHECK Icons (Same as wifi) for displaying selected mode, instead of ugly CHECK ornament unicode.
  • Removed threshold value displayed on panel/notification for lenovo ideapad/legion. When charging limit is enabled (conservation mode), Some models sets threshold to 60% and some models set threhsold to 80%, and the kernel doesnt report what is the current threshold value is, but only informs that charging limit is enabled or disabled. Now it will report only the current mode. conservation mode enabled displays max lifespan mode. conservation mode disable display full capacity mode.
  • Removed threshold value displayed on panel/notification for Samsung laptop. When charging limit is enabled (battery_life_extender), Some models sets threshold to 60% and some models set threhsold to 80%, and the kernel doesnt report what is the current threshold value is, but only informs that charging limit is enabled or disabled. Now it will report only the current mode. battery_life_extender mode enabled, displays max lifespan mode. battery_life_extender mode disable, display full capacity mode.
  • Same goes for panasonic

Version 19

May 12, 2023

  • Dutch translation update (Thanks Vistaus)

Polkit Installation

Polkit Installation: Installation/Update/Removal

  • All devices require privileged permission (root) to change threshold/mode. Therefore the extension will notify the user to install polkit from extension settings. Installing polkit will require privileged (root) access and will need to logout and re-login.
  • During the extension update, if the polkit/ctl file have change and updated, a extension with notify you to update the polkit.
  • Please remove/uninstall polkit first using this extension preferences, prior to uninstalling this extension

Translation

Please contribute translation. Using Poedit / Gtranslator (Available in gnome software). Using poedit Open/create your language.po. Download the po/Battery-Health-Charging.pot file from github. Go to Translation and Update from POT file , translate and submit a pull-request to the main branch on github. Or raise an issue and I will upload it manaully.

Bugs/Issue/Request feature

Please raise an issue on github.

Ratings

If the extension is working well for you, Please take the time to submit a review mentioning the brand/model of your laptop. https://extensions.gnome.org/extension/5724/battery-health-charging/
