Do not want low power mode notifications

I need my phone screen to stay on all the time if I'm using it. I would rather the phone completely die at 20% than give me notifications and slow the phone down. Is there an automation trick that can be done? If low power is turned on. Turn off low power mode? Any help would be appreciated this is a truly worthless apple feature doesn't even save battery if you stay on low power mode your phone will just ignore the settings you have set up all ready
