CONCLUSSION

For media usages (social media, music, video) will get >1 hours screen usages for 10% battery usages

In game online you will get about 30 to 40 minutes screen usages for 10% battery usages

Probably you might get about 9 to 10 hours screen usages by using the phone without playing game and still runing apps with network

NOTE

I recommended to use performance mode or gaming mode if you want play HD+ game
