frame rate error

Shivam868

I play on a Xiaomi 13 t pro which has a high end mediatek processor and I can play on 60 fps normally with little to no frame drops at all but now since this evening I have been feeling and having constant 30 fps (I cross checked using a fps monitor built in my phone), and I checked online couldn't seem to find a fix, has anyone else been having this issue as well?
