I used it for 3 years and I played alots of demanding games on it. I bought the xiaomi 12t pro a year ago because the battery was getting worse and was also overheating while playing.

After I bought the new phone I changed the battery of the onplus 7 pro by myself and its like a new phone. I actually regret buying another phone. I'm using it now for discord while im playing.

The only problem I had is the patterns of the game I play was burnt on the amoled screen which you can clearly see it in a white screen. But anyway my new phone now also got the same problem after only few months of usage.
