The latest Android 15 QPR1 Beta update has correctly enabled the setting to limit battery charging to 80%. This setting allows users to prolong battery life.
Android 15 QPR1 ‘Charging optimization’ menu now works to set an 80% battery limit
Google has been refining the Android 15 OS update for several weeks. The search giant has released two beta versions of Android 15 QPR1 builds so far. The latest beta version of Android 15, tagged as Android 15 QPR1 Beta 2, includes a new “desktop windowing” feature.
Interestingly, the Beta 1 version introduced a notification about enabling a new charge limit. However, among other broken things, users were unable to change this battery charging limiter setting correctly.
Google has addressed the issue with the setting in the Android 15 QPR1 Beta 2. The company states that it fixed an issue that prevented the 80% device charge limit from being disabled (Issue #363170385).
Google has been including several features and functions in Android 15 that help users gain more out of their Android devices. The battery saver feature alone could help significantly prolong the battery’s longevity.
How does the new Battery Saver feature work?
Google introduced a new “Charging optimization” setting in Android 14. It allows users to switch on “Adaptive Charging”. This function ensures battery charging “pauses at 80% and finishes at 100% an hour before you usually unplug”.
Google has added another setting in the Settings > Battery section. Called “Limit to 80%” completely pauses charging once the battery reaches 80% charge. In other words, any Android 15 device with this setting turned on, won’t charge the battery beyond 80%.
In the latest Android 15 QPR1 Beta 2 when users activate this setting, a shield icon appears on top of the battery in the status bar. If that’s not clear enough, the battery widget, lock-screen, and Always-On Display (AOD) state the phone is “Done charging”.
The “Done Charging” notification seems a lot better than the “Plugged-in, Not Charging” notification on Windows laptops. And it is reportedly similar to the Pixel Tablet and Charging Speaker Dock experience.
Numerous studies have indicated that limiting the battery to 80% charge helps prolong its service life. Several Android smartphone users had to experiment with rooting their devices to set this limit. It seems Google has listened to these Android users and implemented the feature.
