Acer Nitro 5 AN517-41 Periodical slow down on battery power

Hello everybody.
I bought a new laptop Acer Nitro 5 AN517-41 (17 inches, Windows 11 Home, AMD Razen 9 5900 HX, 32 Gb RAM, NVidia GeForce RTX 3080 (8 Gb), SSD 1 Tb)
I have a problem - if I start a cold laptop, not connected to electricity, but running on battery power - games periodically slow down a lot. For example, Cyberpunk gives out 5 seconds - FPS 60, 5 seconds - FPS 6, and so on constantly. 5sec- OK/5 sec ugly performance.
I have already set the battery mode to maximum performance - and still there is a problem.
At the same time, there is no such problem from the mains supply.
There is also no problem if I start the laptop from the mains, and then turn it off and play on battery power. FPS drops to 20, but there are no periodic drops after 5 seconds.Consistently low FPS.
Who can knows - whence such periodicity of falling of productivity and whether it is critical? Is it worth contacting the service and will it lead to a critical breakdown of the laptop in the future?

So the slow down is expected as the battery cant give enough juice to run everything, im supprised the power profiles are differnt if its on battery on first boot though. It wont brake the laptop, but it will massivly degrate the battery

It wont lead to the computer breaking in the future, the reason a download speeds things up is it probably causes the machine to route more of the power budget to the CPU and less to the GPU, meaning lower but smoother frame rate . I really dont recomend gaming on battery though!

Thank you, Leostat
As far as I can see, at the moment this is not a problem at all. In addition, if, when starting the laptop from the battery, a large file of some kind of movie or archive starts downloading in the background, there is no such periodic braking of the laptop either!
 It seems that the laptop "slips, periodically stutters" when running one game on battery power, but if you give it an additional load to download some large file, then there is no such slippage.
This problem is not particularly noticeable, but it is not clear to me whether it can be critical and lead to computer failure in the future.

Thank you. I will follow your advice.
I just decided to test fps when running on battery and when running on mains. When starting from a "cold" state of the laptop and in a warm state, with different resource-intensive games (Horizon Zero Dawn, Cyberpunk, etc.)
I can say that the laptop is really good and worth the money. The only remark - when running on battery power, I need to exclude games and work on "heavy" design software.
Thanks, you put my mind at ease 
I hope this post thread helps someone who has a similar issue.
