Hi Todd,

Running the Power troubleshooter may help resolve the issue. To do this,go to Settings> Update & security > Troubleshoot and select Power, then click Run troubleshooter.

Here are other steps that you may need to try:

• Drag the power slider to best battery life and observe your device.
• Perform a clean boot. It is performed to start Windows by using a minimal set of drivers and startup programs. To learn more about performing clean boot, click here.
• Run the Surface Diagnostic Toolkit. This will automatically install any missing driver and firmware updates for your device. Click **here**to learn how to run the toolkit.After running the toolkit, force shutdown and restart your device to ensure all updates are applied.

After doing all these steps, observe your Surface and run the report again.

Let me know how the issue progresses. Similarly, if you have more questions, please inform me by replying to this post.

A 1-2% per hour battery drain is normal for a Modern Standby system.  You system seems to be working as planned except I notice a couple of things you might want to explain.

Your system is never in Modern Standby very long before it goes into hibernation.  Are you manually putting it into hibernation?

The way it should work is you close the lid or let the screen turn off.  The system will go into Modern Standby and be ready for Instant On during that time, and invoking Cortana should turn the display back on.  It will hibernate when the hibernation time setting is reached.  Once it goes into hibernation, the battery drain should stop.

I set my system stay in Modern Standby for two hours and then go into hibernation.  It would be helpful if you could set your system up accordingly and let it do its thing for the day, then do another sleep study where the Modern Standby sessions were a little longer.

The way you use the system will determine how you set yours up.  But, according to Microsoft, Modern Standby uses less power than being in sleep mode, thus there is no actual sleep mode.

On thing I noticed, music will play while in modern standby.  Groove music will continue to play after a specific sleep time has been reached but iTunes will stop at the expiration of that setting.

Also be aware, if the lid or cover is closed, Bluetooth can still pull a system out of Modern Standby, so that is a situation you may want to investigate.

I am seeing drains which seem to be happening while in hibernation.  Is the a new system or an older system?  Your battery shows only 56 cycles, so I assume it is around 6 months old?

Your battery, at one point, was down to 12% .. would that considered normal for your operation in that instance?

I am comparing your report with mine to try to find some explanation for the battery drains during down times.

Answer 4

I have picked out one area on the report which might demonstrate the situation.

As indicated on the graph, the system was in hibernation so no line should have been drawn.  I can only guess, when the system was active again, it saw the battery drain and was confused so it drew the line.

After the line the system went back into hibernation, where it burned 19% of the battery and no line was drawn. 

Does your system get warm anywhere on the device during the hibernation periods?

Thanks for your sharing. I have tried all those steps but it still has the same issue.
