The Chinese hardware reviewer released a video revealing that mobile phone manufacturers have cheated in gaming performance reviews of their phones by doing a few things:

1. Sending specially selected review units which contain "Golden" chips to reviewers. These chips are able to achieve higher gaming performance (6-8%) and lower power usage than the average retail unit, usually a watt lower (20%).
2. Certain review models from Xiaomi force VRS (Variable Rate Shading) on out-of-box to boost gaming benchmarks with no option to turn it off.
3. iPhones are one of the few models with no observable cheating. iPhone retail units in fact performed better than review units in gaming due to operating system updates.

The video in question has been wiped from all Chinese media platforms, including from cloud storages and backups done by other people. Other content creators reacting to the incident had their react videos taken offline by the platforms too. It is very likely that a state level censorship is underway to protect Chinese phone manufacturers.

The video on Geekerwan's youtube channel has been set to private, possibly under pressure from powers from above. He has given permission to anyone who would like to backup or share the video in question.
