Razer Blade 15 Battery life increase?

Out of the box I am getting bout 4 hours maybe slightly more on a full charge watching youtube videos and scrolling through the internet. I am wondering what else I can do to increase this seeing as when this whole corona thing is over I will be traveling to and from work and school daily. I have done all the normal things in the windows settings and I also downloaded throttlestop and undervolted my cpu and everything by -60.5 and also enabled speed shift to 255 and checked the box for disabling turbo. If anyone has any other tips that would be amazing. I'd like to get 6+ hours out of this thing when I am on battery. It is the newest 2020 model with the rtx 2060 btw.
