    Is anyone else having this battery drain issue, I recently updated to windows 8.1. It seems to have drain in standby, like the 8.1 preview did. Any solutions thanks!

    I didn't get the RT preview but I did update to 8.1. No difference in battery from before. I can't say if it is better or worse than before but I still don't need to take the charger with me to work. I get home and its just under a half. You seeing more drain? I would guess you might have some of that beta/preview debug code lingering on.

    Not seen any increase in battery drain since 8.1 on the Surface RT. Went straight from 8.0 to 8.1 and didn't install preview.

    I upgraded from the RT 8.1 Preview to RT 8.1 GA on Thursday night and I am experiencing more battery drain than I did on 8.1 Preview. I already had Bluetooth enabled on 8.1 Preview and did not experience the battery drain on the 8.1 Preview.

    I have tried turning Bluetooth off and it did not seem to help. The only difference in my application mix is that I have installed the official Facebook app that became available with 8.1.

    I just run the powercfg /energy command... seems there is an error with the Tegra. I also found a thread on the MS forum:

    I may be having this issue as well, it sure seems like I'm losing battery on standby but I haven't looked at it closely. I also installed the new Facebook app and it wouldn't surprise me a bit if that was causing problems.

    I will also say that by never letting my surface discharge below 7% I've been able to keep almost all my design charge capacity after 35 charges! this is a LOT better than my first surface which I let die a lot and lost almost 2000mah of charge capacity.

    Moral of story, don't let the battery die!

    My Surface RT has gone from 8.0 -> 8.1 Preview ->8.1 RTM -> 8.1 GA and currently it still lasts about 10 hours doing my daily work- yesterday from 7:30am - 5:30pm when it prompted it is down to 10% battery life. It's always connected to Wi-Fi by the way.

    Hi...

    Been a lurker for some time, but wanted to chime in on this. Am experiencing similar issues Wirth battery life after the update. This is not the only thing though. I'll create a new thread and list the major issues that I am facing - maybe if you guys can comment/ advise etc.

    Thanks.

    Edit: Though, I will say this, I am enjoying using 8.1 - both RT and the regular versions!!! This is what 8.0 should have been! Oh well... better late than never!

    I had a huge battery drain when I upgraded my Lenovo tablet from 8.0 to 8.1. Spent a few days trying to figure out and eventually found the bluetooth driver was broken during the upgrade. I downloaded and reinstalled it and now the battery drain is back to normal. This isn't Surface RT per se but it might help others.

    yes Lenovo issued new drivers on the same day 8.1 came out so I think they were aware of that. I had to do so on my Yoga.

    Activate Bluetooth. This solves the battery drain in standby.

    Alright so after some days I noticed it would discharge faster when I'm connected to WiFi, when its disconnected it doesn't drain as fast! Idk see if you guys get the same result.

    This is kinda related but my Surface 2 has been getting the black screen issue just like my old RT. If it happens again, I'm returning this pos. When I first started getting the black screen I assumed it was the battery. I almost never knew if my battery fully discharged or had the black screen. Anyone have a similar issue?

    Ok, so after running powercfg reports, I also agree that it was my wifi causing the drain. There was a warning in the energy report that stated my router did not support WMM although I was sure it did.

    When I went to my router configuration to verify, I found that it was supported and enabled, so I reset the router and my drain has stopped. I pulled my Surface off the charger at 6PM last night and in the last 24 hours ( 20 of which has been stand-by) the drain has only been 19%.

    I updated from 8.1 Preview to 8.1 GA. Running the powercfg commands listed here Microsoft Surface RT and Surface 2 battery and power | Recharge Surface seems to have fixed the problem. I figure it'd be worth a shot whether you can from Preview or not. I'll report back after having doing more testing.Surface RT only: Battery issue when updating from Windows RT 8.1 Preview

    If you updated Surface RT from Windows RT 8.1 Preview to Windows RT 8.1, you may notice a decrease in battery life. During the update, the wireless adapter power policy isn’t migrated. Instead, the power policy is set to a default value that consumes more power both during use and in the connected standby state.
    To restore the wireless adapter power policy to the correct settings, open an administrator command prompt:
    Step 1: Swipe in from the right edge of the screen, and then tap Search.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
    Step 2: In the search box, enter command prompt.
    Step 3: Touch and hold (or right-click) Command Promptto bring up the context menu. Tap or click Run as administrator.
    Step 4: On the User Account Control dialog box, tap or click Yes.
    Step 5: At the Administrator: Command Prompt, enter the following:
    powercfg -setdcvalueindex SCHEME_CURRENT 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1 12bbebe6-58d6-4636-95bb-3217ef867c1a 3
    Step 6: Then enter
    powercfg -setactive scheme_current

    It looks like this has my Surface now just disconnecting from WiFi when it goes to sleep. Of course it's going to save battery life, but not exactly the connected Standby that it should be. This saga shall continue...
