“Battery Limit” removed from UEFI, but now only charges up to 50%

@Aria, what is the link? When looking up the microsft firmware for Surface Pro 11, The firmware published date is 8/7/2025. On my device, clicking "Check for updates" under "Windows Update", it says "You're up to date".

Aria, could you provide a link please? I only see the previous files dated 8/7 and 8/8 for the Surface Pro 11 and Surface Laptop 7, respectively. Thanks.

@ken and @Gregg
Please note that this is for the Surface Pro. I don't see any updates for the laptop.
I have not tried it myself yet. I am away from my device. Please let us know if the issue has been resolved.

@Aria, I must have gone to the wrong download page. On the Manual Update page there is a new firmware file dated 8/26/2025. I downloaded it, installed, restarted, ...Booting to UEFI, no battery charging option toggle.

I set the Surface App > Battery & Charing to Charge to 100%

I'm charging now, presently at 38%. Will let you know if it gets above 50%.

I updated firmware. The filename was SurfacePro11_ARM_Win11_26100_25.081.7185.0.msi

The UEFI did not have the Battery charging toggle.

I updated the Surface App as well since it indicated there was a newer version.

My surface Pro reached 50%, and it has been there for at least 15 minutes with no change.

I tried the Surface App > Battery & charging set to "Charge to 100%" and "Limit to 80%". Neither setting got the battery above 50%.

@Aria and @Gregg, it's my Surface Laptop 7 that is stuck, so I can't check Gregg's results. However, I wonder if this really is new firmware for the Surface Pro 11. The version number, 1.0, didn't change. The new date on the download page may just reflect when the page was in some way updated. We are all very anxious for this to get resolved. I ask for updates through the case I had opened when this first started, but I don't get any response. It would certainly help set our expectations if a timeline was shared.

I have downloaded and installed the firmware and there is no change - still stuck at 50%.

Hi all, Jeremy said: "When the update is released, it will be made available through Windows Update."

So I think we will get it via Windows Update.

I hope it happens this week.

I have a Surface Pro 11th Edition with a Snapdragon processor. Unfortunately, I'm unable to work properly with it. I’ve tried installing updates and new firmware, but nothing helps — the battery remains limited to 50%, and I keep running into issues when working remotely.

Windows update now has Microsoft Corporation - System Hardware Update - 8/15/2025. It's made no difference though.

Everyone, yesterdays update only contains this in the notes:

"Performance and usability:
Improves wake-up speed by optimizing power management to delay the system’s transition into hibernate mode."

So it doesnt contain a fix to this problem. We will wait for the update that Jeremy mentioned to pass QA and get released.

Basically - MS have removed our devices mobile capabilities for a whole month now without official acknowledgement, communication or a fix.

@ TJ

Jeremy's update below is an official acknowledgement/communication.

I’ve just installed the “Microsoft Corporation – System Hardware Update – 6/26/2025” via Windows Update, and unfortunately, it has made no difference. My device remains capped at 50% battery capacity, and we’re now approaching the one-month mark without a fix. At the very least, we deserve a clear ETA for resolution.

I’ve contacted Microsoft support to request a replacement unit, as my device is still under warranty. However, communication has been inconsistent and unclear.

This debacle is becoming embarrassing for Microsoft. A firmware-level flaw that cripples core functionality on flagship devices to this degree.

So, let me get this straight.. You've all set your battery limit to 50% in BIOS? (I did this too, so I'm currently facing the same issue here).

Now we've discovered the option to set a limit to 80% via the surface app, which is way better than the 50% limit. Finally.

But suddenly, the 50% limit we've all used for months is "unusable", "no mobile capabilities", should be replaced under warranty.. What is this?

I too want the 80% limit, but that extra month without it won't make or break it for me. I'm used to the 50% limit, which still gives me an easy 4/5 hours of work when working on battery.

Jan,

I'm usually at my desk in my office, plugged in. In that case 50% is just fine. Week before last, and coming up next week, I am in a meeting room for 3 days straight all day. Having 4-5 hours with a 50% charge does not get through the day. I'm sure everyone's situation is different. There are probably people who need the higher charge more regularly than I do. It's the difference between successfully getting work done through the day and not doing so. Especially when someone in the room says "I'm sending it to you", and all I can do is shrug. Not a good look.

This seems to affect people who set the 50% limit in the UEFI / BIOS before the update to the firmware was made in early August. When the firmware changed, the option to change charge level disappeared from the UEFI. In the Surface App, selecting the 80% or 100% charge does not enable the device to charge beyond 50%. Somehow a setting got in place deep inside that is not paying attention to the Surface App selection.

Gregg

Jan, the reason we set the battery limit to on is for when we're docking the Surface at a desk and don't want the battery degrading as a result of it being plugged in all the time. But if we never meant for a machine to go anywhere away from our desk we wouldn't have bought an ultra portable Surface Pro or laptop to begin with, now would we? Considering you so infrequently need to go mobile for lengths of time that require the full battery, it should be you answering questions about why you would buy such a product that's evidently overkill for your needs, rather than us having to answer why we'd want to use it for what it's designed for from time to time.

I understand everyone's frustration, and I feel the same. But, to me anyway I can wait for the 'fix' as whenever I am away from a charge point I always carry a USB C 20v power bank with me anyway which will charge my surface 7 at least twice. Surely these days most of us have a power bank?

@ RO'D Not one good enough to charge the Surface, no. Because I don't and shouldn't need one.

Hi @all,

I don’t mean to offend any of you… but you’re being naive. There won’t be a fix. For users affected by the Surface Pro 11 (ARM) and Surface Laptop 7 (ARM), this is a serious issue. I myself can no longer properly use my Surface Laptop X-Elite on the go — and I only bought it two months ago. But if MSFT had given even a fraction of the attention to this battery charging issue that we’ve given it, they would have acted long ago. In other words… if they had truly wanted to, MSFT would have rolled out a fix by now. They simply don’t want to. The number of users affected by this is just not relevant to them. They’ve already written off our disappointment and frustration. I’ve decided to return my device to the retailer. I don’t want to still be annoyed by this issue come Christmas.

The problem seems to have attention: https://www.windowscentral.com/hardware/surface/surface-pro-11-battery-life-cut-in-half-microsoft-is-actively-investigating

At least one person here has worked through Microsoft to return the device and it worked after it was sent back. It's a question of when...

Though, I'm getting close to sending it back as well.

@RO'D, Nice idea: Walmart, Anker - Power Bank (24000mAh, 140W, 3-Port), $88.
