Will undervolting reduce battery discharge while under heavy use.

I have an Acer Predator Helios 300 (i7-9750H, RTX 2060)
I use my laptop as desktop replacement so I keep it plugged in 24/7. I also have a cooling pad under the laptop. So I have had a "problem" where my battery discharges while under heavy use. For example when I play CS:GO or Rainbow Six Siege on Auto Fans my battery discharges for like 3-4 % per 40-50 minutes. The temps are 75-85 celsius. If I turn to Max Fans the battery discharges even faster. And also when I play Apex Legends 3-4 % per 40-50 minutes on Max Fans. I am thinking about Undervolting (I don't need undervolt tips for now) and I know that the temps will get lower but my question is Will the performance get lower and will the battery discharging stop? I also calibrate the battery once a month so the discharge gets a little slower. And also if the undervolting doesn't stop battery discharging, can someone give me tips for stopping it?
Thanks in advance for any help given!

    Perhaps undervolting will reduce battery consumption. However, even if you perform undervolting, when you need to provide more performance, battery power will also be used.

    It is important to note that battery power is also used, even when the power adapter is connected, when it is necessary to provide more performance. This procedure is perfectly normal in current models. Even if undervolting, if it is necessary to provide more performance, the battery will also be used.

    Its kind of normal with few laptops that the battery reduces a bit while playing games even if it is connected to charger.

    Well yes, but what if my battery fries? Quite a lot of people say that when the laptop is constantly plugged in the battery would fry. And then if I don't get a replacement I can still run the laptop I guess but the performance will get much lower.

    Well yea, I have read that everywhere but seeing it discharge frightens me still :P. For example when I don't calibrate it for a long time it starts discharging almost immediately and that frightens me even more. And the thought of that there will be a moment where when even calibrating won't help reducing the battery discharge frightens me even more :D
  • Can you provide the exact model? Example AN515-51-75KZ. Regarding your question, I remember that there was a link provided, in which it said that the battery could be discharged up to 30% and that it would be charged again automatically: https://translate.google.com.br/translate?hl=pt-BR&tab=wT&sl=pt&tl=en&u=https://br.answers.acer.com/app/answers/detail/a_id/48308

    I have read this topic. It still doesn't answer my question. The exact model is PH315-52-75VP.
