I already posted this in the battery issue thread, but its kind of lost in there. So here it is again.
If you turn off the switch via the standard:
Hold Power -> Power Options Menu -> Power Off
option, you will put it into RCM mode. At this point the Switch is still on (albeit with things like screen off it consumes much less power). If you now put your switch away it will drain its battery completely within 48 hours. You are basically leaving it on until it dies.
What you need to do to actually power the switch off is this:
Put in the dongle or get ready to inject -> Hold Power -> Power Options Menu -> Restart while holding Volume Up (+) -> SX OS Startup Menu -> Options (3rd icon as of SX OS 1.3) -> Power Off
This means that you need to inject a payload (or use dongle) every time you want to coldboot and every time you want to completely power off.
You can verify if the switch is in AutoRCM mode or not (in other words you can verify that its still on when using traditional power off) by plugging in the TX dongle without pressing any buttons and watching the LED on it. It will flash blue then green (aka there is power). If you turn it off properly (via SX OS Startup Menu) the LED will stay dark (no power).
I dont know if this is a bug in SX OS (this type of thing is easily overlooked), if it is then they should be able to fix it in the future. But until then either do an extra reboot before turning off the Switch to properly turn it off. Takes extra few seconds if you have the dongle.
Alternatively you can do what Switch was meant to do, and leave it in sleep mode and only turn it off if you dont plan to use it for more than a week.
I would also recommend not docking (or charging) an AutoRCM switch when its in powered off state. Applying power to the USB port turns on the Switch. If it was in powered off state this will take it into RCM mode and it will sit there until you inject the payload (or use a dongle). This means many hours or possibly even days of Switch being on in RCM mode constantly draining and charging the battery, this will destroy your battery. I would ONLY put it on the dock/charge when the Switch is either On (you are playing a game), or its in sleep mode.
Hope this clears up the confusion. If you are paranoid you can use the dongle LED trick to verify for sure that the Switch is Off and not in RCM.
