The Switch doesn't have good battery life?

I think I read that when it came out. Might depend on the game. My battery seems to last long enough, I haven’t needed to charge it with my USB battery yet.
Looks like it’s down to 56%. Probably because I leave it on, in sleep mode, instead of turning it off.
Oh, and if you are wondering, it won’t show up as a drive if you plug it into your computer. No easy way to get screenshots off of it. Don’t have a Twitter account. To lazy to remove the micro SD card.
