    Left the house again. Put to sleep decreased from 62% to 53% in4 hours. Sad
    Then disable instant go... Let it hibernate.

    Finding an alternative is not the point, the piont is that type of drain in sleep mode should not happen..

    My sleep drain is only 1% per hour now after all he updates. I used to have terrible sleep drain loss, but not anymore. i5/128GB SP4 setup.

    Well this whole "Connected Standby / Instant go" is a whole new thing to me. My older laptop did not have this sleep mode.

    I see no benefits of this "connected standby/instant go"

    It's supposed to be similar to a phone, where you can get updates, notifications, etc., while it's in a low power state. However, I don't think it works very well. Or maybe I should not care so much about the drain loss rate. Your hibernation approach is probably better :)

    I took a bit of a sermon on this forum for embracing Hibernation over Sleep, but I still have no regrets.
    In my opinion the SP4 is an excellent candidate for this approach because of 2 factors.
    1 It boots up dramatically fast even from an "off" state. So the minor difference in boot time between hibernation vs sleep is hardly consequential.
    2. It is a Beast of a computer for running on a battery, regardless of which cpu it has. That amazing display can be a burden. So the additional battery life from choosing hibernation might be a worthy gain.

    And this is what I don't get... If i close my surface pro and leave the house... Or heck, even leave it upstairs while I am downstairs.. Why do I need to be receiving notifications?

    More than likely, whatever I am receiving notifications for, I will get from the app on my phone as well.. and even if I am not.. I am not AT my surface pro 4 .. so how can i check these notifications that i am receiving? :/

    It does not justify the battery drain... and with a 5-10 second start time... Hibernate is the obvious answer.

    I have it turn off Wifi when I am not using it to save even more battery.

    A phone is connect to either wifi and/or cellular, yet phones dont drain that much while in sleep mode.

    I put my sp4 with wifi off when in sleep mode so nothing should be connecting, also removed app background usage. Yet it still drains, it is a legitimate issue that should be addressed and resolved.

    A 10% decline in battery over 3-4 hours in sleep mode is not something that can be overlooked. If this much drain happens in sleep mode, it is worst when using the device.

    In all fairness, comparing cell phone demand on battery vs a Surface demand on battery is not apples to apples.
    Not even close, really. It's true that we can do a lot of things with our phones more energy-efficiently than we can with the much larger and powerful form factor of the surface.

    But even saying that, if you were to crank up that phone and hook a mouse\keyboard to it and keep the screen alive with continuous use, you might be surprised how fast that battery drains.

    I agree that the battery life on my SP4 i5 kinda sucks. I had to drop my CPU to 50%, my display to 15%, and my GPU to minimum performance to get even close to Microsofts claimed all-day battery life. Gaming between classes is a no/go without access to a wall plug. If it weren't for the Qi-Infinity 35000 mAh battery, I would have returned my SP4. I'd be an instant buyer if they released a good power cover for the SP4. I actually waited to buy an SP2 until the power cover was released, and skipped the SP3 because the Power Cover wasn't compatible. The SP4 was a big enough upgrade to coax me over anyway, but the battery life does suck. I need REAL all-day battery life, not theoretical all-day battery life.

    I understand the desire. But a SP4 that actually got 9 hours of battery life using it like many folks do, would not be a SP4. That packaging is almost magic. It's certainly art.

    Don't use chrome.

    IE11 or Edge (if you can handle it) ..

    Either way, Windows 10 is not great when it comes to efficiency.. its worse than Win 8.1. In fact, Win10 acts more like Windows 7 than 8.1 , unfortunately.

    That's... that's still pretty terrible. 1% per hour means your device will die in its sleep in 4 days. Compare that to iOS or Android where devices can sleep for weeks before the battery dies.

    Are the IOS /Android devices in the same sleep state? Where it gets notifications etc when sleeping and allows for "instant resume" ?

    I think the answer there is yes... as for notifications and instant resume, etc. I was under the impression that Windows 10's sleep function was inspired by phones.

    But the processor in a phone is fundamentally different from an Intel processor, so while you can try to program a sleep mode that is similar... they won't be the same as the end result must be achieved through different means.

    This coming from the guy who's never used sleep mode on a PC though, so take it for what it's worth.

    On my M3 Surface Pro 4 I stated in a comment earlier that MS Edge is one of the leading factors of battery drain. It always runs the CPU super high. I have noticed this now on all my devices running Win 10 (Vaio laptop, Dell Venue 8 Pro, Surface Pro 4).

    Recently (after the big TH2 update) I updated my hosts file with a comprehensive list of all ad sites and such. Since that, Edge rarely uses high CPU. Maybe due to Edge not being able to block ads yet it is constantly churning in the background processing these things?

    Not sure, but updating the hosts file has made a HUGE difference, and now I can use Edge as my primary browser without worrying about a battery hit. Not sure about others, but I actually like Edge.

    Had it a few days and been through just one cycle. It was under 4 hours which really surprised me. I did expect something better than that, especially as it is designed as a portable product.

    9 Hours of battery life is probably screen set to 30%, battery saver on, Airplane mode, etc. Why does everyone think when ANY company says 9 or 15 hours of battery life they think streaming Netflix (Huge battery drain from pulling data and the app), or playing a game (taxes out the CPU), or having brightness on 70% (thats around 300 nits which is 100% brightness on most laptops. 9 Hours has always been around 5-6 hours of real work, 15 hours has always been around 8-10 hours of real work. Notice the new Dell XPS 13 says 11 hours now instead of the claimed 18 hours of battery life lol. Tell all manufacturers to run the exact same test using the exact same brightness, wifi, bluetooth, brightness (controlled), and anything else that draws power. Otherwise it's all BS isn't it? Since I have owned every Surface and Surface Pro I knew exactly what it was going to do. But since I have owned thousands of laptops I know pretty much what all of them will do based on battery capacity, screen brightness and technology used, power consumption of the processor, RAM, etc..
    Actually, when Apple says 9 hours, you typically expect to get 9 hours or more.

    Getting about 4 hours battery life (Surface pro 4, latest Fall update and firmware update, just surfing and watching some videos, edge and chrome. If it doesn't improve in the next update, I will return this device. 4 hours battery life is both unacceptable and abysmal for a premium device in 2015. Apple Macbook Air and iPad 4 have over 10 hours of battery life.

    Can you try disabling Adobe flash in Edge and also uninstalling Flash completely.. see if that makes any difference. Flash is a known battery hog (reason why Apple do not install it on ios)

    I use a Qi-Infinity 35000 mAh battery to extend my SP4 i5 to all day usage. It's relatively small and light... about the same as a mid-sized external hard drive. It fits in my smallish computer carrier, along with a bunch of other gear.
