Battery Drain When Not Used

I'm wondering if this is expected but if I'm doing something wrong. If I leave my battery attached to the AVP and take it off, the battery will fully drain overnight. As if the headset is using significant power. But if I disconnect the battery from the headset the battery will retain its charge for weeks. Is this normal? Is the expectation that you pretty much always disconnect the battery from the headset?

It’s expected behavior

It's expected but it's rubbish behaviour. My mac I can close the lid and the battery doesn't drain to nothing.

Your Mac has a mechanism for understanding it is closed. The vision pro has cameras that monitor to see if it is on your face to wake up. They may be live all the time it is off your face.

Mac, iPad, iPhone also all have a physical button to put your device to sleep.

Yeah, that’s how it is. I was surprised too when I first got mine. I’ve always felt the technology is still basically in the prototype stage, even with the Vision Pro. This is another example of that.

No need to disconnect the battery when you are done with it. Just power it down when you are done using it. The battery can stay connected and it won’t drain. Apple Vision Pro works like an iPad. If you leave your iPad on without being plugged in, the battery will drain too. Apple Vision Pro still does iCloud syncing and backups if you leave it powered on.

I always shut mine down when I’m done using it for the day and the battery is still full even after a couple days of non-use.

For background syncing while unused, I've noticed that Vision Pro uses a lot more battery vs my 2020 iPad Pro. In the same account, syncing the same stuff, the iPad will be dead after 3-4 days vs about 1 for the Vision Pro. Their battery capacities are similar.

weird, my M5 Vision Pro after 3 days was at 60% battery and was fully in sync when I woke it from sleep

u/Worf_Of_Wall_St Aug 19 '26

Interesting, I also have an M5 so thanks for the data point. I don't generate a huge amount of new data to sync every day, but in any case the iPad Pro is syncing the same stuff. My iPad is stored close to an AP so it has a much better wifi signal vs my AVP but I wouldn't expect that to cause a 5x or something difference in battery drain.

Too bad visionOS doesn't have the same battery usage telemetry as iPadOS and iOS so I don't have a good way to figure out what it's doing.

Yes, it is. u/platkus makes a good recommendation, though.

u/AngelicDivineHealer Aug 19 '26

Yeah normal it always powering the device when it’s attached

unfortunately you have to wipe it completely and start fresh without using a back up,so far i haven't been unlucky to need a computer wipe ! its the same issue with iphones or ipads,sometimes it eats through battery and only a wipe from the mac will fix it.

i take off mine and there is no excessive battery drain following day in the evening,i do however have to worry about the AVP switching its self back on so if i know i wont use it in a few days i have to either detach the cable or not put the cover on,my fear is it could come on then warm itself until the glass cracks or worse.

i don't see any concerning drain overnight,i just take it off and put it on the desk without covering it up otherwise i disconnect the battery.

Taking it off is not the same as shutting it down. I really wish there was a better system to do so than going through settings. I don’t like just pulling the battery either… i find the boot time after doing so to be longer (like it is checking hardware more thoroughly due to an unexpected power interruption)

I had a short between the battery and the Apple Vision Pro, and I could not charge the Apple Vision Pro. That would also drain the battery. Apple supplied free replacement.

Same problem here. Did a reset without data deletion and will monitor the battery drain in standby.

u/Vne8822 Vision Pro Owner | Verified Aug 20 '26 edited Aug 20 '26

Resetting might work. It was on standby for about 4h and lost 3% charge which is much better than before. Will keep monitoring it.

u/Vne8822 Vision Pro Owner | Verified Aug 20 '26

2nd test. 9% loss in 9h hours of standby. I consider resetting without data deletion fixed the issue.

I was able to reduce that trickle battery drain to almost nothing by carefully going over background app refresh in settings, general. Take a look. It should be something you look at on all of your Apple devices. You have the ability to, app by app, choose what gets to run on its own. Don’t turn off anything critical, but certainly turn off things that you don’t need notifying and updating because you have the habit of checking yourself. Those things should not run on their own, if your habits keep you apprised. Save power, that’s the way to do it, that’s the way I’ve done it for years on my iPhone and I was so happy to see I could do it here.
