What it is

A frontend to a Mediatek service that fully takes over Android's own Adaptive Battery management. Uninstalling this app will only remove the UI component, but not the system service that it's controlling. To completely disable Duraspeed you need to have it enabled first, open Duraspeed app via Settings, and set the toggle to 'Off'. Otherwise Duraspeed service will continue running despite there not being a Duraspeed entry in Settings which will lead to unexpected app freezes that affect FOSS apps such as Dialers/Phones and messengers.

Commands

adb shell pm uninstall --user 0 com.mediatek.duraspeed

To put it back:

adb shell cmd package install-existing com.mediatek.duraspeed

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
