Diagnose battery drain on your tablet with Windows 8.1's Sleep Study tool

Windows 8.1 users can now find out which applications are draining their battery during sleep hours of their laptop/tablet using a tool called Sleep Study.

Microsoft has published a step-by-step guide over at the Windows blog, detailing the use of Sleep Study and how users can benefit from the tool. During sleep, devices with connected standby or InstantGo, continue to carry out certain low level tasks at minimum frequency. Tracking the battery usage of these low frequency tasks cannot be carried out by traditional logging as it would itself use up battery. In order to tackle this, Microsoft has built the Sleep Study tool which can be used on Windows 8.1-running systems which support InstantGo. Interestingly, the Surface Pro and Surface Pro 2 do not support this feature while their ARM-based counterparts do.

Using Microsoft's own guide, users can find out whether their system supports InstantGo, run Sleep Study tool and get a detailed report in HTML form. The report will provide users with details such as battery make, list of applications which carry out activities during sleep, graphical representation of battery drain.

So what we have here is a continuation of an old Windows tradition: coming up with tools or utilities with which users may attempt to work around what are basically design flaws or oversights in Windows. This should not even be necessary, really....

Right. So Windows is the only operating system on the planet where third party applications have the possibility to effect battery life in standby or connected standby ? It has nothing to do with design flaws in the operating system at all.

Could not edit my post...

Just tried this on my Asus T100. Found out that auto. Maintenance was enabled... I thought i had disabled that. Guess not :)

There is a reason that Surface Pro and Surface Pro 2 are not supported by this tool - they do not support Connected Standby or InstantGo as it is now known.

Surface Pro 3 supports this, along with the RT line, because they all have the InstantGo.

I don't really see much battery drain on my Dell Venue 8 Pro. Left mine last night for 12hrs, lost 4.8%
not really terrible

I have the Dell Venue 11 5130 with mobile keyboard. After applying the BIOS and wireless card updates, my tablet can last over a week in standby.
