If you're referring to the throttling of certain apps and games then I believe the latest firmware update adds an option to turn that off. If you have that latest update then I guess you should be ok. Not sure what that GOS app update is though, but I don't believe it is related to the throttling.
Yeah well without the throttling it's going to be overheating even quicker I guess, if not draining the battery quicker, but FPS should be better in the first few minutes of gameplay.
That's great SoT, I've never broken 7h on mine, but I haven't tried to optimise it either. On the other hand, I did the same thing with my S21 Ultra and I was getting 12h SoT from day 1...
