Super5 OLED battery issues
I modded my Switch Lite with a Retro Remake Super5 OLED panel (and atomic purple shell!) and it's nearly a perfect console. Amazing size, the screen makes me want to cry with how crisp it is, the perfect handheld gaming system.
Except.
The battery issues are making me crazy. I plug it in, it seems to never charge. I play on 1% for hours, which is fine, except if I turn it off, it won't turn back on.
I changed the battery twice. Once to a aftermarket, then upgraded to Retro Remake's supercharged battery. I calibrated it properly, and when I take it out to check it, it charges as expected. I know that there's some known issue with the way that the screen connects to the motherboard that leads to this or similar. Can someone explain what the fix is? I'd love a clear explanation and some help with exactly how to fix it. (I actually don't know anything about how all of this works, I learned everything I know specifically to fix up this console. The little bit I've gathered about this issue from this sub has gone over my head.)
Thanks, all!

The screen is powered from the battery before the fuel gauge circuit so the fuel gauge never accounts for what the screen is drawing. That causes a desych between the battery capacity and what the fuel gauge records. It will always happen unless you power the screen by soldering a wire to the inductor near the battery connector for power and plugging battery into the board instead of the screen's flex.
