Though they're getting a little long in the tooth, Microsoft is continuing to push new firmware updates to the Surface Pro 3 and Surface Pro 4. Today, the company released a fresh set of fixes for both devices (opens in new tab), bringing improved battery stability to each while enhancing system security for the Surface Pro 4, specifically (via Neowin).

Here's a look at what's new:

Surface Pro 3

  • Surface UEFI – Firmware: 3.11.2550.0 improves battery stability for devices not in use.
  • Surface Embedded Controller Firmware – Firmware: 38.14.80.0 improves battery stability for devices not in use.
  • Surface Integration – System devices: 2.0.1350.0 improves battery stability for devices not in use.

Surface Pro 4

  • Marvell AVASTAR Bluetooth Radio Adapter – Bluetooth: 15.68.9125.57 improves system security.
  • Marvell AVASTAR Wireless-AC Network Controller – Network adapters: 15.68.9125.57 improves system security.
  • Surface UEFI – Firmware: 108.2318.769.0 improves battery stability for devices not in use.
  • Surface Embedded Controller Firmware – Firmware: 103.2241.256.0 improves battery stability for devices not in use.
  • Surface Integration – System devices: 1.0.176.0 improves battery stability for devices not in use.

Today's firmware updates come alongside the release of September's "Patch Tuesday" updates for Windows 10, which bring their own set of security fixes for everyone.

If you're still using a Surface Pro 3 or Surface Pro 4, you should be able to snag these updates now via Windows Update.

  • "improves battery stability for devices not in use" I hope it improves battery stability for devices that are shut down. I can shut my SP4 down on a Friday afternoon and it will be down to 70% by Monday morning.
  • I swear my SP4 need to be charged every time I turn it on, but I don't use it every day. Why?
  • I had this issue last year on my Surface Book, but one update earlier this year fixed.... however I have other glitches that I truly dislike of the most up-to-date firmware...
    my clipboard used to discharge after the keyboard was down to 45% of battery... right now they both discharge more or less at the same time, which makes it a lot less ready to use as tablet when detach because it will most likely have little battery life
  • Same here but with my surface book 2. Purchased last month.
  • same with me here, my SP4 fully charge to 100%, turn it off, open in the morning and showing only 83% on battery
  • Think I got these when I moved to insider builds the other day. Standby battery for sleep definitely seems great. Not sure if it's because of this firmware update, a previous one, or the OS update. I tend not to use sleep too much as it was a trainwreck when SP4 launched so I stopped.
  • Fantastic news that Microsoft still cares about us SP3'ers 😍 My SP3 is still going strong and is serving all my on-the-go purposes and even some heavy-lifting.
  • I'm still using my SP3. I got these updates on 09SEP2018, Indiana, USA. Standard Win 10 Pro. of course I'd love to have a new SP but my SP3 is still going strong too.
  • My screen cracked on my sp3 and I don't know why. No drops or anything
  • Heat could do that. Maybe there's a battery issue? Does everything else work OK? I'd be worried (though I'm hardly an expert here).
  • Was hoping that this new firmware would fix the bug that had broken the surface pro 3 keyboard but alas no. Still can't use the 109 pound keyboard that is now little more than a cover.
  • I'm already update SP4 yesterday, fully charged it. shut it down until morning. and hoping the battery still 100% this morning, i turned it on.. and... the battery remains only 83%.. did i over expected to this statement "Improve Battery stability for device not in use"? i really expected to solve battery draining issue while SP4 not in use (Turn off).
  • Man I must have some good luck, the only complaint I have with my SP3 is the battery. I actually just left it outside in a rainstorm where we got 3 inches of rain, didn't notice it was still out for 12hrs. I packed it and the keyboard in some rice for 3 days and turned it back on this morning. Good to go! I was not looking forward to another $1500+ in a replacement. Phew! I just have to get a new case.
  • I have a Surface Pro 4. I just got these updates yesterday and now none of my wireless devices (BlueTooth / Network) are not working. I tried restoring but that failed. Any thoughts?
  • I uninstalled a Checkpoint VPN and the issues cleared up.
