If your charging animation is missing or glitchy, you can typically fix it by manually replacing the animation files within your device's system directory or through a custom recovery.

Apps like Pika! Show or Battery Charging Animation 3D allow you to download and apply professional-looking animations without needing to flash a ZIP file.

Download the Chargingstate.zip or a similar fix file from reputable modding communities like GitHub.

Extract the contents into the .tmp_update folder on your SD card.

Go to Settings > Modes and Routines > Routines . Create a new routine: If Charging status is "Charging," Then change the Lock screen wallpaper to a specific video or animation from your gallery.

Advanced users can manually add animation files to /system/media/charging .

If you aren't trying to fix a broken system file but just want a new look, you can use built-in features or apps that don't require risky system modifications.
