after 15 mins of gaming the phone did not heat up or have any frame drops, it consumber 4% battery life so if we do the math u can get a 6 hour screen on time while gaming, when we did the same test on the s23 ultra the phone heated a lil near the cameras and lost 6% battery in 15 mins so if we do some math there you would only get aroung 5 hours of gaming screen on time, this shows that s24ultra runs cooler while gaming and even though both phones have the same 5000 mah battery s24 ultra has more battery life as per this test.
