I face heating issues on my new Iqoo 12, It heats either slowly up or asap within 15 mins while gaming (Wuthering waves and Genshin Impact Medium settings),

Bought the device 8 days ago I rarely had 2 moments in the 8 days where the device didn't heat up and had a normal slight warm but for the most part of the 8 days I've always faced the heating issue I'm suspecting of a defective piece or a software update (I'm currently on PD2307BF_EX_A_15.1.8.9.W30 update)

Please give me some reply that it can be fixed or else I have to take time out to reach out to the service center for the replacement as a defective piece
