Android 15 integrates a Device diagnostics tool that allows you to check things like the current battery cycle count, screen operation, and more. The option was spotted in the Android 15 beta 3 update from June. Now, the latest beta 4 update makes it visible and functional for everyone.
In Android 15 beta 3, the tool was in an earlier stage of development. So, it was not available by default, but it could be enabled. Also, some options still did not work correctly. Now, the beta 4 update includes the option in the device’s settings without you having to force its appearance.
Android 15’s Device diagnostics tool lets you know your battery cycle count and more
As reported by Android Authority, all Pixel devices running the latest Android 15 beta 4 update will show a new “Device diagnostics” option under Settings > System. It is located at the end of the list, just above “Reset options.” The tool has two main sections: Component health and Evaluation mode.
Component health allows you to verify that everything is fine with key components on your device. For instance, the screen test shows layers of multiple colors, so you can check both color reproduction and the possible presence of dead pixels. It also allows you to test if the touch input works correctly. Likewise, this Android 15′ Device diagnostics section lets you know the cycle count of the battery and the health of the storage chip.
On the other hand, Evaluation mode enables you to check the operation of a secondary device. It works by scanning a QR code from the other device. After scanning it, it will run the same tests mentioned above. The Evaluation mode also allows you to “validate” the tests done on your main device. In both modes, the tool will provide a report on the general status of your phone’s key hardware.
A useful complement to the Pixel diagnostics tool
The option is ideal if you want to rule out any hardware problems on your device without going to a technical service. If you want to do more in-depth tests, you can still use the Pixel diagnostics tool by dialing *#*#7287#*#*.
