You're right about that. It also depends on the kind of games you have on it. Some heavy games tends to make them heat up very fast.I really don't think there are any, most would get too warm/hot and end up being damage to the device.
I haven't used any that's good at such without overheating.Any smartphone that can be able to run for long without being overheated is good for gaming. The memory space is another great addition to it.
I have come across several reviews about the phone Asus ROG Phone and it looks like it's a good deal for mobile gamers.Is the stream deck an appropriate answer? Probably not. While I don't do much mobile gaming and never purchased a phone for the task, I do see many of the benefits they added to the Asus ROG Phone. Custom-fit controllers, moving the USB port to be on the side for landscaping use, all seem like things I would want in a gaming phone.

Naaah, I don't do that. It kills the smartphone battery fast.Do you play games with your device plugged into the charger? If yes, that could be the reason.
