Iqoo must include this feature inwhich:

1. All apps are listed under deep freeze option

2. Users can turn on the button in front of them.

3. The functionalities of this button will be to completely freeze all activities and every process of this app, until the app is opened (may be given a grace period of 2 minutes to run after closing app.)

Deep freeze will significantly improve the battery lasing of the phone.

I am using IQOO Z9s 8/256 gb variant.

I witnessed that even after putting app to restricted battery use (in app info), the apps still manage themselves to restart themselves in the background.

Also, just like we have access to control wifi/ mobile data for each (app under network management in iManager), there should be option to control battery usage of each app at one place.

As a listed way, easy access to app battery usage of each app as Unrestricted, optimized and Restricted option would be much helpful.

Overall, deep freeze apps, will be of much use.

Since many of us use many apps once in a while, and after that they secretly keep consuming battety in the background.

Thank you for your attention.
