Sometimes Predator Helios 300 Predator PH315-51 will drop the fps and Battery Indicator flash

First of all, my laptop is Predator helios 300 (Predator PH315-51)

When I use it to play some games like GS:GO, Rainbow 6 Siege or sth like that, it does give a very nice performance.
But sometimes, usually played after 15~20 mins, the fps will drop into around 15~35 depends on wt game i was playing. And it will last lasted around 1 to 2 mins until it became normal.

When this phenomenon happened, not only the GTX 1060's fps will drop, but also the Intel's graphic card.

And I found that when the fps drop, the Battery Indicator will turn to amber and flash until the fps become normal.
Also if I replug the the charger, the fps and Battery Indicator will become normal immediately.

And I only play games when this laptop is charging. Can anyone find a solution for me please?

Btw I think the Battery Indicator will turn to amber and flash is the key of the problem.

So here's an update after near 1 year.
To find what is happening, i downloaded some softwares to monitor my laptop. Then I found sth from XTU.
This problem only happen when XTU say there is a Power Limit Throttling, then I try to undervolt my cpu by changing the Core Voltage Offset to -0.160V.
Now I have tried it over 5 months and that problem seems to be fixed.

However this "fps drop" situation happens again when I join the BETA test at Ghost Recon: breakpoint, then I check XTU again and it said Power Limit Throttling. So this time I try to undervolt my cpu to its limit(means it will work fine and won't shut my laptop down), which is -0.190V.
It has been a few days and everything is fine. At lease for now. So I guest it is cpu power limit problem?
