DELL G5 UNUSABLE ON BATTERY

Dell G5 purchased in October 2019 is basically useless when running off of battery power. When plugged in, the machine works wonderfully. When running on battery power, anything more than a few browser tabs is resulting in serious performance issues (clicking lag, video stutter, games unable to get past the initial screen, etc).

I understand that the machine will throttle considerably when running off of battery, but I'm blown away that the machine is essentially useless. I want to be able to run newer games at low-spec settings on battery (games the machine is able to easily run at ultra-specs when plugged in). Any suggestions on how to improve my performance?

Things I've tried:

-Optimizing game settings using Nvidia Experience

-Disabling integrated graphics

-Turned off intel speed shift and intel speed step in BIOS

-Adjusting "power mode" performance scaling slide bar

-Changing power plans (no performance option is given, just 'Balanced' and 'Dell recommended')

Nothing has changed the computers horrible battery performance. Any suggestions??!
