There’s nothing to really tweak on Android because it is Android which hides most things from your control. I did everything I could. If you play every day and charge every day it’s fine. But if you treat it like a classic handheld you will be frustrated.

A real handheld like a Gameboy Advanced can be left in a drawer for a year and ready to go. That’s the experience that a Linux retro gives you. You don’t have to constantly think about charging. It’s instantly ready whenever you are.
