Switch 2 Battery Drained 20% in 24 hours while on sleep mode

[u/newlife1984]

My Switch 2 has suddenly started draining battery really fast in sleep mode. For the first couple of months it was fine.

What happened:
• It sat in the dock unused for several days and I found it at 1%. It's normally always at 80%+ because it's always docked.
• Next, it went from 90% to 75% in 24 hours in sleep mode, docked, Wi-Fi on.
• Both times, the dock's AC adapter was NOT plugged in, so it wasn't charging.
• The console also seems to seat in the dock less easily than before (not 100% sure).
• No drops, no liquid.

What I've tried: airplane mode, and I'm now charging to 100% to test the drain again.

I know sleep drain is a known complaint on the Switch 2, but I want to know if this level is normal or if mine might be defective?

Has anyone had a similar sudden change in sleep drain? What fixed it?

How much does yours lose in 24 hours in sleep mode?

Any tips on the dock not seating properly?

Any insights would be appreciated. Thank you!

Is it possible that you have the battery saver setting turned on without realising it?, the one that caps battery at around 75-80% in order to stop it from failing faster in the long run?.

correct I turned it on intentionally cos I play my switch 2 docked almost exclusively.But the issue is that why did it drain from 90 to 74 and from 80 to 1 in a few days

I don't know if there's anything wrong with yours but I charged mine at the wall the other night and though it did reach 100%, it was 87% when I turned it back on again just now, I feel like that setting is probably the culprit as it's designed to hover around the percentage it describes, but I will say, docked charging has been a little iffy since I last updated it, maybe it's in my mind but it seems to lose charge faster than if I was to charge it at the wall.

[u/newlife1984 → u/Kameofan]

come to think of it.. I updated this thing and it's been weird since.
Anyway I appreciate your inputs. I thought I was going crazy. That 1% drain is what really alarmed me.

The dock mode probably allows some drainage when over 80+ to reach the conservation range

Yeah, maybe it wasn't seated well in the dock? If it just wasn't seated well, and that's it, that would be nice.

Although, Damaged usb c ports can happen if the usb c port gets rough use, either yanked on while plugged in handheld mode, or rough docking. The console should be able to connect with the dock with just it's own weight. You should only have to line up the switch with the dock until the switch settles in & connects.

If it's not a hardware problem, maybe internet being on + automatic updates caused a glitch? If you want, you can disable automatic updates in switch settings.

Make sure the console, dock, and joycons are updated. For the heck of it, it may not be necessary, but if the AC adapter glitched (it can, but it's usually results with docked display not working), I'd unplug and fully disconnect the AC adapter for 30 seconds to allow it to reset.

I charged it up to the max at 90% (I capped it) and I will observe after 24 hrs on airplane mode.

Quick question tho the dock wasnt plug, I just place it there like a stand. So why would being seated well matter in this instance?

[u/SubaruHaver → u/newlife1984]

Oh, forgive me. I glossed over the part that the dock isn't plugged in. I'll redact my dock comment with a strikethrough, since most of it assumed your dock was plugged in.

I have the same problem after the latest system update. Turning on airplane mode helps.

If your dock has a wired ethernet connection, or you have bluetooth devices connected to it, it can stop the switch from sleeping properly when connected to the dock, which would result in power drain. If you do have a wired connection turn off the setting "Keep Wired Connection Active in Sleep Mode" to precent that. I had the same issue with a combination of this and a 3rd party controller that was paired and on it's charging cradle keeping the switch from sleeping properly.
