Version 0.6.6#
November 14, 2026
- Back on the Snap Store. Install with
sudo snap install battery-health-center. The snap runs in a sandbox, so power modes and GNOME's power-saving settings stay in the apt and Fedora packages; see Install for what to connect and what the snap can't do. - Nothing changes for the apt and Fedora packages.
Version 0.6.5#
November 9, 2026
- Help opens the right page. The help button, F1 and User Manual now open the manual page that matches the page you are on: on Charging they open the Charging page. See Finding your way around.
- What's new. This page lists what changed in every release.

Version 0.6.4#
November 8, 2026
- Help button and user manual. A question-mark button at the top of the sidebar, F1 and User Manual in the main menu open this manual in your browser. See Finding your way around.

November 7, 2026
- More Linux Apps. The About dialog links to Voltkit and ThermalPrint, with their official icons.
Version 0.6.1#

- Screen reader support. The charge ring and the charts are named and described (the latest value and what the colors mean), level bars announce their value, icon-only buttons have names and decorative icons are hidden. See Accessibility.
- Clearer charts. Chart colors keep at least 3:1 contrast on light and dark cards, and periods on the charger get a strip along the bottom of the chart so they do not rely on color alone. The dark theme's accent keeps 4.5:1 with white button text. See Battery level and power.

November 4, 2026
- French and Simplified Chinese. The app is now available in English, Spanish, German, French and Simplified Chinese, following your system language.

- A refreshed app. New navigation with a sidebar, adaptive workspaces, a modern battery icon and a branded About dialog. See Finding your way around.
- Dashboard columns. Overview, Health and Usage use two columns in a large window, while Charging and Power use one centered column so settings stay in reading order. The columns stack in a narrow window.

- Clearer energy numbers. The app explains how the app energy estimates work, and empty charts say what to do. See Apps using the most energy.

Version 0.4.4#
November 1, 2026
- First-launch question. The first time you open the app it asks whether to record history in the background, so history is not lost when the window is closed. The answer is remembered, and people who already had settings are not asked. See Your first launch.
Version 0.4.3#
October 28, 2026
- Updates reach the hidden copy. The background copy started at login used to keep running the old version after an update. Now, once the program file has been replaced and no window is open, it starts the new version and exits. See Record history in the background.
