How to Restrict Mobile data and wifi completely for specific apps?

[Steejo]

While using apps like Mx player Ads pop up due to mobile data being  turned on. My previous Oppo device did let me to completely block data to my player, so ads won't pop up due to my player not receiving internet. I can't find this option in my galaxy M51. if someone know an solution for this please let me know. Thanks 😊

doesn't samsung max drain battery?

[Nick95]

Nope, it's system application

[Steejo]

it was draining 20%of my battery daily

[Nick95]

Actually it acts as VPN, but thing in Android since all data tunnels through VPN server, Android system couldn't differentiate who is consuming Battery, so it add VPN app as consumer instead of original application which is running.
In short term, that 20% battery consumption reported by Android is false.

really

[Nick95]

he is asking about power consumption of Samsung max, not data usage.
