Calling all gamer friends please help!

Let's get right to the point, shall we?

So, I've been playing a couple of games on my phone for a while but lately with every update the game just gets heavier, and I can hardly play on my phone for an hour and a half before It overheats and the game starts to slightly lag.

I have an iPhone 11, had it since 2022 and it's actually still in good condition, like I have no problems with it except that I can't play my games for long which sucks. I can't afford a PC nor a PlayStation for now because I'm saving for something else.

So, I told myself I'm gonna settle for a Tablet\iPad, I did think of getting a gaming laptop, but I already have this laptop for my writing and Netflix and work, so I don't really want another laptop and also considering I also wanna get my sister an iPad for her games and drawing as well.

In short, I need you guys to give me tips or Tablet recommendations that can hold like at least two or three hours of gaming without overheating.

I've done some research of course but I just really don't want to regret a purchase in the long run, y'know?  

I've heard that the Xiaomi 6 pro is good, but they don't sell that where I live, unfortunately. We only have the Xiaomi 7 series and the Redmi ones, I was gonna settle for the Redmi Pad Pro but then I saw the Samsung s10 plus has a bigger battery and a larger storage option than the Redmi.

I would rather not risk it getting something online like I'm gonna go to the best store I know so I can check it out myself and everything.

My main problem right now is storage, overheating and short gaming time with my phone, like the main purpose of buying a tablet is just so that I have a place for all my games.

Anyway, I still want other people's Input like what do you guys think?
