The iqoo severely suffers the heating issue. The iqoo says it's trying to achieve a better thermal management. Even after their many attempts. This was never resolved. Playing an optimised game like COD mobile etc. The temperature easily rises upto 15 °C -17 °C from the initial temperature 35 °C. And this phone is only 2 weeks older. Gaming is not the only area where this issue is prominent. Other functions like vedio calling on WhatsApp, photography etc also have the same issue. The heat issue are getting worse after the updates.  Other brand's  phone with having same processor does not seem to have this issue. Most of people buy this phone hoping it to be an entry level gaming phone, which is being failed to achieve by iqoo. The developer team need to seriously work on this issue. The iqoo users does not need alot of new features that much as Funtouch 15. They need a reliable phone with just sufficient feature.
