I'm trying to recall. I know we always had a solid supply of rechargeables underway. I also distinctly remember that there is a kind of blanked out hand off screen between players because of fog if war. I don't recall it having any kind of sleep function. But I know it could run for several hours no issue. I don't recall having to mind the batteries in particular.

Sorry I can't be more helpful.

Some Game Boy Advance games actually had a software-based sleep mode!

You pressed L+R and Select.

On top of that, I was always really impressed by the GBA’s battery life but maybe I’m just old.

Same, I just don't remember ever bothering about the battery life (unless it turned red) but with that long gaming sessions it would be a concern for kid me probably.

I even remember buying a nice glacier blue rechargeable battery pack and never using it!

I wish I could buy everything in glacier blue now.
