USB-C Hub drains battery? Macbook Air M1

Hey all, I experienced the same problem as described. I was talking to Apple Support and they replaced my MacBook Pro M1. After receiving my new MacBook I noticed that the problem still exists. It would be interesting to see, if anyone experienced the same issue with the Belkin USB C Hub (USB C Hub from Apple Store) ?

I am using one from a third party, ordered from Amazon (Cable Creation USB C Hub Multiport Adapter).

Hola. Same issue with Anker 7 in 1 USB C hub. First disappointment was that it draws about 12w from the charger so Air only has 18w of usable power at which point it says that it isn't charging (even though it does, but slowly). Wish that was mentioned before by Anker, I mean it is a good selling point tbh for you to purchase an a more powerful adapter.

So to avoid slow charging, I was connecting the hub separately from the charger. When leaving the hub connected to the Air and shutting everything down it is still a little warm to the touch, meaning it continues drawing power.

Hey I experience the same thing, I've even recorded a log of how the battery is drained with and without the USB-hub, check it out:

93% 12:54 (With hub)

90% 13:06

83% 1:30

73% 14:16

68% 14:32 (Without hub)

65% 14:57

64% 15:05

62% 15:20

61% 15:27

59% 15:42

57% 15:57

56% 16:08 (With hub).

55% 16:12

54% 16:15

53% 16:18

52% 16:22

51% 16:25

50% 16:29 (Without a hub)

49% 16:36  

48% 16:44

47% 16:50

46% 16:56

As you can see from this log, when a hub is connected to the device, 1% battery life only lasts you 3-4 minutes, whereas without the hub, 1% lasts you approximately 7.5 minutes, which is almost double the amount.

I'm using Ugreen 9 in 1 hub.

Yes I have this problem too, it drains EVEN if shutdown, and EVEN when nothing is connected to it !!

It is so annoying and inconvenient !

I wish you report the issue too (I did) to Apple developer feedback to raise an alert, so that they care to fix this issue

you can use this link

Apple has released an update to Big Sur that may help with your issue. 11.2.2 is available in the app store What's new in the updates for macOS Big Sur - Apple Support

macOS Big Sur 11.2.1 addresses an issue that may prevent the battery from charging in some 2016 and 2017 MacBook Pro models.

Is it what you meant?

Or maybe this? macOS Big Sur 11.2.2 prevents MacBook Pro (2019 or later) and MacBook Air (2020 or later) models from incurring damage when they are connected to certain third-party, non-compliant powered USB-C hubs and docks.

Are you using a "pass through" powered hub that you connect

your charger to and then to your MacBook Air?

If so, the 30 watt power brick that came with your MacBook Air

is too weak to both power a hub and all its peripherals and you

MacBook Air. One thing none of these hubs specify is how much

power they "steal" from the charger before delivering it to the computer.

I understand this. In my scenario the MacBook is not connected to the power supply, it's using power from the battery, thats how I know that its draining faster than when disconnected.

Thanks!

Of course it is because the hub has to draw its power from somewhere

to work so it is drawing it from your MacBook Air. How much a hub will

draw depends on the manufacturer and what manner of components

are being used in the hub or attached to it.

I also have a MacBook air m1 with similar issue.

But a little different. The problem is even when the Macbook air is shutdown, a connected USB-C HDMI adapter connected to a monitor will continue to draw battery power even the monitor is powered off. I normally has a type-c charger connected also to the adapter.

This is annoying as it drain my battery power overnight even though I didn't use it. And it means at least one more charging cycle per day.

I bought a Vention 5 in 1 adapter and I have encountered a similar issue. At sleep mode from 23:30 to 7:30, the adapter drained 9% of my MBP M1 battery. I wonder if this is a common problem among adapters (battery draining) or if expensive Apple adapters are exempt from this issue at all. Hope someone with Apple adapter can help me to testify.

yes, i thought i'm the crazy one here

i just experienced it yesterday, usually full charged macbook will last me almost 2 days of usage

but i used 100% from 3 PM to 10-11PM, it only lasted me around 38%

usually the remaining power will be like more than that

and i only watch youtube and do some light browsing

then i realized i plugged in my anker usb hub, and thought maybe it is the problem

and i only connected 1 wireless mouse

i better get the new bluetooth mouse then

and hopefully apple fix this soon

In my reply to the original post I mean "update your Macbook to see if it helps".

It didn’t help
