========================================
Hi! I just switched from an asus zenfone 5z (snapdragon 845) to an asus zenfone 7 pro (snapdragon 865+) and the performance in games is very poor compared to 5z. I tested and the processor frequency never exceeds 2ghz. The frequency in games is as follows: core 0-3: 1.3-1.8ghz, core 4-6: 1.7ghz, core 7 1.6ghz. So the processor never stays at its maximum capacity. 5z was always at 2.8ghz, even at 70-80°, but zenfone 7 never exceeds 45-50 ° and still stays at low frequency. Also at the first antutu or geekbench test I was scared, because it took 500k antutu points and 500 single core points in the geekbench, extremely bad for what sd865+ can do. And when I actually sat with the phone in my hand next to the fan to cool it, it performed correctly (690k). I don't know if it's from the new android 11 update, but it doesn't seem normal to me that at such a low temperature the processor becomes weaker than an 845. So it doesn't heat up and it still decreases its frequency extremely much. It is impossible not to reach these temperatures, it reaches 50 degrees when you open an application, so how can it underclock like that?

For a very short time it ran at normal frequencies. 3.1ghz on the last core and 2.4 on the 4-6 cores (60-80 fps) But then its frequency decreased again and the fps decreased a lot (20 fps)

The phone was put into performance mode.
I hope you can help me. Thank you in advance!

Since the server pushes update notice to different serial numbers by batches, it may take some days for you to receive the FOTA notice. Thanks for your patience. You may tap “System updates” in [Settings] >[System] to check if there is new firmware available. Or, you can also try to manually update firmware by referring to the following link.
