ok so i put my ROG Ally to sleep by pressing power mid-game, and when i picked it up later it showed this:

Battery low
Connect the charger soon. The device will go
to sleep automatically at 2%.
Last full charge: 1 h 52 min ago
it lost 10% per hour asleep... that makes it hard to rely on as a grab-and-go device. is this normal for handhelds, or is something keeping it awake??
i bought a handheld speicfically to be able to pick it up and play for ten minutes. Right now i cant trust it to have any battery left when i need it. thx in advance!!
