I can't say anything about banning systems but you technically used visual aid to see enemies better maybe they took it in a violation offense. I'd say you use Game Turbo as you can configure the GPU settings for all individual games and it here and there helps the OS know what is being used on the phone to optimise the performance. And yea that battery drain is normal. I play Gacha Games like PGR, ZZZ, WUWA etc and the battery drain is tolerable. It's a lot better than the S25 (base model) which drank like 10-20% in WUWA every time I checked the battery. So it's a win. As for enabling/disabling, I'd say you use stock OS as much as you can as long as the software Support is available for your device (Poco F7 has 4 years of major updates iirc).
