Lower Down your performance of your iPhone whil playing arena. The phone will get still hot but not as same as when the GPU/CPU is running at full capacity.
Another tip: don’t keep your screen at full brightness. Lower it down to minimum
iPhones 7 and higher will run the game as fine even with power mode lowered.
I do believe that the new pause feature in the game is running at all times & that’s what is causing the phone to run 100% of capacity at all times while playing it. And so to overheat.
