Open the battery screen and look what app is draining it. Then put it to sleep.


I just got mine today and by the time I drove from Dallas to Gainesville (1 hour), it drained 25%....I only watched two short music vids on youtube.


@John Higgins i think because its new when i bought it it was drain fast after using it for 1 months the battery health very very good it drained 20 percent every 3 hour of use


I don't think I'm going to take that chance because it'll be past the return date... I'm just going to get the OnePlus 9 pro.
