    Okay so I just ran a movie on Netflix for 1:11 which only took 11% battery. But I used my surface for about 2 to 3 hours that took about 25 to 30%. Does that sound about on par on the battery life consumption.

    That sounds about right. Mobile devices are really good at decoding video and playing it. Some have chips in there designed to so just that super-efficiently. Surfing the web on the other hand can involve a lot of processing power to render web pages. Those numbers you gave out are plausible. Some tech sites use HD video playback as a benchmark for battery testing. That time is usually higher than a web page cycle battery test.

    If I am correct then you should get over 9 hours. You watched video for over an hour. Then you said that 2 hours used 25% of your battery.That 2 hours *4 = 8 hours. Plus your 1 hour for video. That's 9 hours. That ain't no perfect math by no means, but it seems to be a fairly close estimate to me.

    Yeah, I was reading Anandtech's review and their web browser battery life test squeaked out 8 hours for the S2 and around 6.8 hours for the S1. But while I'm actually using my S2 it doesn't seem like I have any hope of making it to 8 hours. If I was losing 10% an hour then I wouldn't worry too much, but I'm losing closer to 20% an hour. That seems excessive or that could just be what happens when I leave my brightness at max and leave bluetooth on, lol.

    I haven't charged my Surface 2 since about 8 o'clock yesterday. I currently have about 15% battery left. However, that's less than 2 hours of web browsing. I couldn't imagine making it to 4 hours.

    Yesterday, I did two hours of browsing and a four hour session of Remote Desktop and used 60% of the battery. I have checked my powercfg battery report and have projected battery life ranges from 6 to 10 hours.

    Connected standby does take some battery when idle. You can check which apps are allowed to update and limit to just those you use in PC Setting/Search and Apps. There are new features in 8.1 that can effect battery life that were not present in 8 RT on the Surface 1.

    I notice mine says that the firmware doesn't support any of the S# sleep states and the WiFi doesn't support power saving mode. Is mine in error or does the Tegra 4 not support these things and/or will Microsoft update the firmware to do this?

    I haven't had time to do a proper test, but it seems even with Bluetooth off as Microsoft's tech support recommended to me and screen brightness sitting at around 25% I am still in the 6-7 hour range (extrapolating from two hours of near constant use).

    I just don't get why this is. I suppose I should attempt turning off all of the synching just to see if that has an effect.

    If not I'm going to have to drive to the Microsoft store and ask for an exchange.
    Wasn't there an odd quirk a few months ago during one of the beta versions of Windows 8.1, where turning on Bluetooth increased battery life, for some odd reason? Perhaps some of that faulty code survived to rebirth itself on some Surface 2 models? It's as I said before, you're getting worse battery life than my Surface Pro 2, which is truly awful.

    I don't think Bluetooth is at all related considering I saw no change in battery life after turning it off.

    Tomorrow I'm going to put both my Surface RT and Surface 2 side by side and run some kind of battery test on them to see how they compare. If my RT wins I'm bringing the Surface 2 in to the Microsoft Store on Saturday and getting it exchanged.

    Just did an hour and a half straight of Word. Bluetooth on and WiFi on, nothing running in the background. Started at 99% and ended at 83%. Seems legit. Unfortunately, I don't have my S1 still to do a more direct comparison. But that was just Word. The battery would have drained faster if I mixed in some web browsing.

    Guys what I been noticing is that sometimes when i browse the web and using word, the device would not get warm and other times it would get warm to touch (usually when it gets warm battery life decreases faster.) I usually browse around forum sites. I think there is alot of stuff running in the background at certain times. It Schedules to do maintence and dont forget WINDOWS DEFENDER does automatically do scans everyday. So I think thats something to look at. Is there a way to stop windows defender from doing scans?

    I believe you can set it so Windows Defender simply doesn't start up with Windows.

    Burning 70% battery life while playing Facebook games on the IE explore and surfing the web for 4 hours total time, Is this normal?
    I feel this is not, and wanted to get some feedback if this is normal or so. Because I am ready to exchange this surface 2 for the fear of a faulty battery. I have one more day before my 15 day return\exchange is up at beat buy. What are your guys' feeling about this.

    I think that is probably normal. What I'm discovering about the RT (Surface 2 should be better) is that the Surface is optimized for media playback. If I continuously play videos (.m4v, .mp4 format) off of a microSD card I get well over 10 hours of use. If I surf the web, I'll get closer to 6-7 hours. Putting the Surface in standby I'm noticing anywhere between 3-5% battery drain over night.

    Going to the desktop and running Task Manager, I've seen many processes still running. Apps that I had started since booting up show up in the list even though I closed them out (by a downward swipe). I need to do some investigation as to whether or not those dormant entries have an effect on battery life.

    that actually makes me happy to hear. That's about what I average for an over night drain too. And I know I could get about 2 hours more of use with 30 % left too (give or take). I think I am being to hard on this thing comparing it to my iPad two. Which can go almost a whole 12 hours and only burn about 50% or so. And I also realize ita essentially a stripped down computer as well. Which is going to demand more power then the likes of an iPad. Well I guess I won't bother exchanging it. Plus there a 1 year limited manufacture warranty. So if there is anything wrong with the battery alls not lost. Right?

    But remember that the iPad 2 is only rocking a 1024x768 resolution. The higher the resolution the more juice it sucks.

    I used their tip to let my battery drain below 10% before charging and I swear it improved the battery. Or that could just all be in my head.

    I always let it run down to around 10 percent if not let it fully die than charge it.

    EDIT: Been using my surface more and more, and notice in the task manager sometime the windows search filter ( which is the service that index your file and stuff) is running and uses alot of resources with it. This is while i was browsing the web. I disabled the service but that made windows search really really slow. So i put it back on. Anyways, when this runs in the background, battery life takes a big hit.

    This is interesting. Got to pay attention to this. They should have set it up in such a way that when the Surface is on battery, it should stop doing the indexing and resume only when attached to the mains.

    It's considered a maintenance task, so whenever your Surface is set to perform maintenance (check via the Action Center), that's when it'll scan.

    I believe you can set it so Windows Defender simply doesn't start up with Windows.
    If you it on start-up, then real time protection won't be enabled. Granted, I suppose that's not the biggest issue for a Surface 2, seeing as it runs Windows RT, but nonetheless, you lose real time protection until you re-enable automatic start up, or manually open it while logged in. It's you decision to decide whether or not that's and issue, but it's just a heads up.

    That's actually a new "feature" on Windows 8.1 (and not, the quotes are not saying it's bad, they just mean it's not widely published). When you close an app, it won't fully close. Instead, it's "tombstoned," where the app and it's processes are suspended to where they're not using system resources, but also not lost either. This means that you can close an app, not have any adverse affect on your system performance, and still come back days later and pick up right where you left off. And should you open up anything particularly resource hungry (like a graphic intense game that eats up RAM), Windows will automatically remove the tombstoned app to make the memory available to the rest of the system (this can be done manually by closing the app via the Task Manager).

    This is exactly how it works on Windows Phone. It's also very similar to how hibernating works on Windows 7, where the session is cached, yet not utilizing power. It's pretty neat, and I've thus far not seen any adverse affect on battery life or performance. And again, should it be bothering you, you can always kill them manually via the Task Manager.

    My Surface 2 looses 1% per hour when it's in standby during nighttime and wifi is switched on. When I go into flight mode, it looses nearly nothing. You can turn off notifications during nighttime in settings, maybe microsoft should give the possibility, to turn off wifi as well, or bring out a firmware update, that lowers the idel power consumption of wifi. It is advertised to have a standby time of 7-15 days, with wifi on I would only get 4 days..

    .
    Not true, even when its not in maintence mode. SOMETIMES it still appears in task manager and uses 25 percent of the cpu.

    Um, it's common knowledge that devices with lithium ion batteries need to be discharged periodically.
