Once downloaded, you'll have direct access to battery settings from the Settings app's home screen, free with the tweak. You'll also notice it looks the same as in iOS 9 ; if you activate the feature, the battery indicator will be yellow , otherwise it will be white.

If we go into the settings we can see which system options it disables to save energy , and we can also choose which options we want to work or not with the tweak.
