As for gaming, you're better off sticking with simple titles. We were able to run PUBG Mobile, but only at its low settings and that too with a lot of jerkiness. Asphalt 9: Legends also ran, but with some serious lag that made it much less enjoyable than usual. We also found that the back of this phone got quite warm after two or three races.
On the other hand, the battery lasted us comfortably through a full day of heavy usage which involved taking a lot of camera samples, playing these games, and about two hours of video streaming. Our HD video loop test ran for 11 hours, 44 minutes which isn't great, but isn't too bad either. We were able to charge up to 25 percent in 30 minutes and 51 percent in an hour using the included 10W power adapter.
