    Battery drains while on sleep mode.

    Since the win 10 upgrade i am facing issues with my laptop. Earlier when i used to put my Laptop sleep mode it doesn't used to wake up, so I used to power it off and restart it again, now that got fixed on itself somehow. and now new issue has come up, now my computer's battery is draining while it's on sleep mode.

    I am using Asus zenbook UX303UB
    Intet i5 6th gen
    8 GB , 1 TB HDD
    nvidia gtx 940m

    This is not really a cure, more of a workaround, but my Asus laptop would drain the battery after about 2-3 days of sleep. So I just hibernate it.

    Sleep does rely on keeping certain parts of the laptop powered up and so its normal to see some battery drain, perhaps a few percentage points per 12 hour period.

    Sleep can be problematic on some devices and is often due to driver conflicts. That has been a problem that goes way back in history.

    Hibernate is probably the best option, although Ten should be capable of booting up very quickly given that it has 'fast start' enabled by default.

    When I updated one of my tablets to 1607, it began having severe battery drain in sleep.
    The display driver was somehow replaced during the update with another one; changing it solved the problem.
    Make sure all device drivers are up to date.

    Sleep Mode has never been efficient. In all my years of using laptops, I've always just turned them off and on. Battery drain is normal for sleep mode. Some people have had issues with the laptops not powering off completely and draining the battery, but if that's your issue, there is an easy fix. You turn off Fast Startup and check a setting in Device Management under Intel Management Engine.

    That shows a problem. I think typically I might see 5 or 6% fall in as many hours. Your issue is almost certainly not a 'fault' as such, much more likely a bad driver that's not unloading correctly. No easy fix without doing a lot of legwork and trying to isolate the cause (and uninstalling random stuff only to have to reinstall is never a great idea). If you wnet down that route then I would advise to make a disk image first, then have a play and see where it gets you, then restore back to the image.

    Have you tried DeaconFrost's suggestion to see if that helps ?

    If it doesn't then tbh I would just not use sleep. Windows 10 with fast start enabled should be really quick booting up on modern hardware. I could be here typing this reply in little over 15 seconds from hitting the power button.

    even mine has a slow battery drain, using Win 8.1. Even when powered off, not in sleep or hibernate, but off. It still uses the battery to keep the clock going.
    Turn off fast start, as suggested, hibernate over sleep as it uses less power, and if you aren't going to use it for several hours, shut it off.
