How to charge S24U to 80 percent...

Hi there,
Android has the ability to limit battery charge to 80%.
I did get a Chargie a year ago but couldn't get it to work, so I tossed it.
I find it hard to believe that in this day and age, that Windows 11 doesn't seem to have that ability. And I'm sure that many may wish to be able to do.
Currently I have to try to remember to disconnect the charger before it reaches 100%. Oft times I'm unsuccessful.

Does anyone have a solution?

To limit charging on your Surface Pro 11, you can use the "Battery Limit" feature in the Surface UEFI settings, which restricts charging to 50%. You can also enable "Smart Charging" which will limit charging to 80% when the device is plugged in for extended periods.

Here's a more detailed explanation:
1. Battery Limit (50%):
* Access UEFI: Restart your Surface Pro 11 and press the Power button and the Volume Up button simultaneously when the Microsoft logo appears.
* Navigate to Advanced Options: Choose "Boot Configuration" > "Advanced Options".
* Toggle Battery Limit: Toggle "Enable Battery Limit" to "On" to limit charging to 50%.

2. Smart Charging (80%):
* Smart Charging is an automatic feature: Surface devices have a built-in feature that limits charging to 80% when it detects prolonged use while plugged in.
* You don't need to enable it: Smart Charging is enabled by default.
* Check if it's enabled: In Windows 11, Microsoft will tell you if Surface smart charging is enabled with a small “heart” icon below the partially filled battery meter
* Note: The 80% charging limit automatically turns off when the battery has been discharged below 20%.
* To charge to 100%: You'll still need to leave your Surface on the charger while it fills up that last 20 percent of its battery.
* Open the Surface app: Select Start and open the Surface app.
* Select Battery & Charging: Select Battery & charging and from the Charging mode section, select Limit to 80%.
