    Despite moving from 8.0 to 8.1 RT GA, I applied the fix via the command prompt. Still losing about 10% per hour - with WIFI on, BT on, brightness at around 45%, and with the Mail App syncing 3 mail accounts. This was certainly not my experience when using 8.0.

    Does everyone suffering the battery drain have SkyDrive syncing enabled? I noticed that during the Preview that my battery life was terrible when the syncing was set to automatic (all sync setting set to on) but after I changed the default storage and camera uploads to off the battery drain disappeared. Never had the problem since Preview and GA.

    Well, I do have SkyDrive as the default storage location and the sync is automated. Would not want to turn that off though.

    Saw this on Neowin. According to MS, there's a problem with the wifi config if the Surface was upgraded from 8.1 Preview to final release.

    Thanks. Yeah, saw that. But I applied it to my RT and I got about 8 hours of battery life with the following use profile: WiFi on, BT on, IE11 open with 4 tabs, alternating between MS Word and PPT, SkyDrive Sync on and actively used, and Mail app open with 3 accounts actively polling to download mails as and when they arrive - so constantly. I thought that was as good as what was advertised originally about the RT.

    The only thing I did not try was to check how long the battery lasted in connected stand-by mode. Will probably do that over the next couple of days or so.

    That's what mine is doing too... and it is disappointing. I would expect no more than a 1% drop over 7 hrs of standby.

    according to that logic the RT should not need to be charged for a month. I think battery technology is not ready for that yet. That may work if you turn it off- but only maybe. Even then you loose charge.

    That's what I'm currently experiencing on my iPad. It is not unreasonable. Standby is standby.

    I'm going to recheck the battery drain on the Surface RT. Under "typical" usage and keeping apps open when I go into standby, I was experiencing about a 6% drop over 7-8 hours.

    This morning I made sure to close all apps (including the desktop) and go into standby. After nearly 9 hours, it dropped by only 2%. I think that the WiFi issue was only one of a few reasons why battery life was less than expected. Looks like there might be another.

    Ok, so I applied the fix and after a full charge 48 hours ago, my battery level is still at 64%. This is more like I was getting with WinRT 8.0.

    After applying the powercfg fix I got two and a half days with fairly heavy usage (not a good estimate of actual usage time). Seems to be back to normal though.

    OK, after 72 hours, the battery level was still at 55% and dropped to 45% during 4 hours of use last night.

    I am pretty happy with the battery life after 8.1. Update so far.
    Not much has changed. Slighty better under usage, and also better in standby. =)

    Havent had to charge my surface all week, just plugged it in this morning. Its getting much closer to my ipad...........I don't really use my ipad anymore, but the standby time is like 2-3 weeks. I could literally go 2 weeks without turning it on, and there will be like 40% left on the thing. Surface gets used much more, so a week of use before charge is pretty solid.

    Looks like the recent updates as of late have eliminated the battery drain. Good thing. Now my tablet screams.
