    Update: 8-26-18 (I was typing this and hit back on my mouse..... Lost a bunch of updating stuff.... So if this is blunt, that is why)
    My experience with AutoRCM was going great until I as well started having battery drain issues after turning my switch off from Horizon. This started after I put my switch into the dock and after that, my switch would just reboot into RCM mode after being powered down. To my surprise, after powering off my switch, plugging in the SX Pro Dongle would stop the switch from booting up or rebooting back into RCM mode. Which puzzled me. So as of now, my switch just stays in sleep mode :)

    Info:
    • To fully turn off your, you will need to power off via Horizon, and boot the CFW you use and hit "Power Off" in that menu. This will fully power the switch off as I have been told.
    • I have also seen that holding the power button for 8 seconds or more while in horizon will trigger a force power-off (I have not tested this)
    • You can charge your switch with AutoRCM installed. This requires you to charge it with the power brick that powers the dock. I have had to this already and I can say that it does work.
    • Since AutoRCM corrupts the BCT (*BCT is the boot configuration table), which results in the switch not being able to charge normally while in RCM mode.
    • Switch does not charge normally with AutoRCM, a.k.a corrupt BCT.
      1. Either it charges very slowly or sometimes with a broken slow/fast/slow/fast charge pattern:
      2. Or this behavior is current taken from the USB controller or the BPMP (Nvidia's Boot and Power management processor)
    • In AutoRCM, the Charge IC probably can't update the battery calibration file and could make the percent fake.
    • I have not experienced Battery De-Sync Issued with AutoRCM. This seems to be a misconception that scares people away from installing AutoRCM. Afaik, AutoRCM do not cause De-Syncs.

    I installed briccmii the moment I heard about it and then never touched my Switch after that (battery was at 100%). Sometime later, I wanted to test something quickly so I booted up Hekate and went into Horizon, both CFW and OFW. Battery was still at or near full once I turned it off from the menu, not from Hekate or by manual shutdown. I think either the next day or sometime later when I wanted to check something else, I turned on my Switch with Hekate only to find battery around 30%. Needless to say, I removed AutoRCM and have never touched it since. It should also be worth nothing that the creator of briccmii, @rajkosto experiences this issue from time to time so he might be able to shed some light on this issue.

    I've had the opposite affect. I had my switch off for 8 hours, 3 times so far, and the battery has stayed been the same after turning it back on. Just odd.

    After installing auto RCM via SX OS I immediately had issues. The "software" battery fix worked though

    Like you had desync issues? Or the battery was draining while the switch was "off"? I'm afraid to do the sync fix with autorcm installed just because people are having issues with it.

    I like to idea of Autorcm but the current version of it...not so much. If we could have an option to deactivate and reactivate it at will, then that'll be golden!
    And the interesting thing is...if it can corrupt the boot files...can we corrupt them to boot into CFW all the time (say incorporate @CTCaer's payload) ?

    We are corrupting the boot0. No custom edits other than that. It just forces the switch to boot into RCM mode. Cant do anything else right now

    My memory is a bit hazy on this which is why I didn't say it but I think I docked my Switch after testing with Hekate the first time. This might be the difference people are looking for since this does not turn on the console, normally, and only charges it. Regardless of whether I docked it or not, I should also mention my Switch was neither on or in RCM prior to me finding out its battery was around 30%.

    I use AutoRCM (brickmii v2) and have no battery drain problems long as I keep my Switch in sleep mode.

    I was having desyncing issues, my switch kept dying at the 40-50% mark. Oh and I uninstalled auto RCM before running the "resync" tool.

    Nope. To do that you have to resign your one BCT with nintendo's private keys. Impossible..
    Otherwise, there wouldn't be a reason for warmboot in lower than 5.x firmwares

    The dock powers on the switch. It doesn't only charge it.
    It's the same boot procedure when you plug it in dock or wall adapter or PC.
    So if you had AutoRCM, it was powered on and stuck at RCM the moment you touched the dock's USB port.

    Btw, I'm more than 3000 hours in RCM till now (I always forget it, even for a day some times).
    I still don't have the de-sync. But also I don't use AutoRCM (no need hmmm:unsure:).

    I used the AutoRCM option that comes with SX OS. For the first few days I put my Switch into sleep mode when I wasn't using it, and my battery barely went down at all. Then I turned my Switch off completely for about a week with about 87% battery left and when I came to use it, it wouldn't turn on at all. NXLoader and TegraRCMSmash wouldn't recognise it at all. Put it in the dock for an hour or so and it finally managed to turn on with 3% battery, left it in the dock to charge.

    So in my case at least, it seems better to leave it in sleep mode rather then turning it off completely, as somehow this drained the battery completely empty.

    I thought RCM was safe to be in, that AutoRCM was the issue.

    I only installed autorcm yesterday, but haven't noticed any issues so far. I thought it was mainly using Linux (which I didn't and don't plan to use on Switch) that caused battery problems *fingers crossed*

    So if you use auto rcm its better to run the resync battery payload sometimes?

    I went from 1.0.0 to 5.1.0 with the guide and if I turn the Switch off it's dead the next morning

    Did you use briccmii to repair the cust_data? If so then it's not that... maybe I'm just lucky?

    Is it true that if you boot into the SX OS menu and choose power off from there, the system will truly be powered off rather than RCM? I heard that somewhere just once, might be bogus info. Because normally when you power it off from the OS, it just goes to RCM as far as I know.

    AutoRCM installed. If powered off and undocked/off of the charger the system goes from 100% to dead in less than 24 hours. It seems like upon powering off it automatically starts RCM. I haven't tested extensively but it's happened twice. I assume it will happen everytime so I just leave it in sleep mode.
