A famous Chinese tech channel, Geekerwan, compared each manufacturer's media trial & normal retail devices and found out most Android manufacturers are lying in some or most aspects of their gaming performance, and Apple is the only one that doesn't fake its gaming performance (somehow perfom better during the comparison).

It's not really news for these manufacturers faking their capabilities (e.g., fake camera demo photos or Samsung reducing gaming performance by software limitations). But the reason why it's viral this time is the manufacturers' (or CN government's) actions; both YouTube and BliBli (local streaming sites) videos got taken down in days (even the re-uploads are constantly getting banned/taken down). Made everyone suspicious about the manufacturer's actions (or government officials because the YouTube ones are also taken down quickly; not many companies can achieve that.)

TLDR: Yet another manufacturers' scandal.

Why doesn't Apple need to "pretend" while Android needs it? 

More info: the brands that were caught faking their phones' gaming performance are

Oplus (Oppo, Realme, OnePlus): FPS cut to 50/45 instead of 60, CPU frequencies lower than the media review model during gaming (e.g., Find X9 series, OnePlus 15/OnePlus Ace 5/6 series)

Vivo (iQOO): Wattage consumption is higher than the review model (e.g., Vivo X300 series, retail version up to 1.3 W compared to the media review device.

Xiaomi: Severe stutter and performance issues compared to the media review model 

(Ex, Mi 17 series/Redmi K90 series)

Honor: The retail version gets hotter and has higher power consumption (Ex: Honor Magic 8 & 8 Pro/Win/GT Pro/RT).

ZTE (including Nubia/Redmagic): Higher temperature on the retail models.

(Ex,Nubia Z80U/RM11 Pro)

Some Android manufacturers got caught faking their smartphone performance.
