Razer Blade Pro 2021 - Battery performance

Hi, I just received the razer blade pro, lovely laptop. However, I know battery life won't be great but is there anyway to make it run on full performance on battery (Specifically the i7 processor) ? I have tried to change the battery mode in windows and made sure that 100% processor is used in minimum and maximum state but there is a significant difference on battery and plugged in mode. Thanks for your help! Nathan
