RG40XXH Knulli Battery Drain

Hey guys! Is there a way to make Knulli stop draining the battery on my device after i turn it off? It only happens on Knulli, i have other cards with StockOSMod and MuOS that don't have this problem, but knulli looks so much better with Emulationstation.. The only way i found was to remove TF1 after shutting it down, but it's a pain if i have to do it all the time..
