Macbook 14" how to disable usb-c charging

[max_md]

Hello

I have purchased my first Macbook 14"/16GB/1TB (I have used windows machines for 30 years). I have connected 2 monitors through usb-c. Can someone tell me how to disable usb-c charging when MagSafe is unplugged. I do not want to charge the battery all the time due to its health issues, but my monitors are still charging when plugged to MacBook.

Thanks for your help.

EDIT:

I have installed aldente but the MacBook is still being charged despite the 80% limit.

I’m not sure it’s something you can just turn off. If it’s possible it would likely be an option on the monitor itself.

MacOS does a great job of smart charging your battery to prolong its life - I’d be tempted to trust it to do its thing rather than try to manage it yourself manually tbh.

You are wasting your time worrying about battery health. Let the machine manage it. There are plenty of other computer specs that are much less stress-inducing to obsess over, like trackpad temperature. Or maybe take up hot-rodding instead, so you can monitor the vacuum pressure in your car engine.

Use AlDente app. The supported list hasn't been updated but some users here reported that it works fine on the new MBP. Just set it to 50% if you're planning on just plugging it in 24/7 . It'll stop it at 50%.

Thanks for the replies. Hope that aldente will work fine on monterey. It started to limit battery charging. Sometimes it works and sometimes it doesn't work and I don't know why.

macOS regularly stops charging your Macbook above 80% or it will let the device use battery (even while plugged in) to drop to 80% and stay there for a while (it is smart, does it after a while on times that you'll regularly be plugged in).

Don't worry too much about it ?

My Macbook Pro Intel's battery is at 85% health, 1.5 years later.

Haven't used it since my MBP is still on the way. But it should work just fine. If it has bugs it'll prob get fixed later when they add the new MBP officially as one of the supported models

AlDente is working fine now on the newer M1 MacBook's; I have installed it on a Pro 14".
It appears the Apple BMS does most of what you need for battery health, in that what you see in the Menu Bar battery app is a padded version of what the BMS is report. Such that true 95% from BMS = 100% from UI. So Apple is not really pushing the cells to 100% which would be bad.
The AlDente FAQ goes into this more.

I still like greater control over charging, discharging and full re-calibration cycle, and personally think this is a good idea to get maximum life out of a LiPo battery, if my knowledge of vehicle BMS and EPCC translates! and having had 2 previous MacBook battery die within 3 yrs (less than 80% health, and the dreaded switch off suddenly at say 30%) then it is worth a punt on my new M1.

Back to the original question.
You can stop a monitor back-charging your MacBook or any connected device; by using a USB-C Hub that does not support charging! Search Amazon (or your favorite retailer) for USB Hub Charging Not Supported, these are the cheapest hubs around $15. Plug it into your monitors USB-C lead and leave it there for whenever you need to plug in your mac.
