Split from this thread.

My SP4 gets very hot and drains the battery very fast even though it is asleep. I found it very hot in its sleeve and down to 28% earlier today. Found it dead later in the afternoon. This is one of MANY issues this device has.

(My SP4 is not part of the insider program)

Hi All,

We released an update on 2/17/2016 that addresses this issue.

We recommend that you install this update to keep your Surface performing its best. You can get updates now by checking Settings> Update & security> Windows Update.

To confirm the updates are installed, check Settings> Update & security> Windows Update> Advanced options> View your update history.

Thanks,

Josh

    last week, I just reset my SP4 with fresh recovery image,and then patch to all 4/19 updates.

    but I still have the battery drain issue. I check it's LockAppHost which costs the most battery energy.

    who can tell me the workaround?

    Same here. Just update with the May 9th updates, rebooted, logged in and went to do something else. Come back to my Surface, fans screaming, HOT. "LockAppHost.exe" has been running. Surface was docked all the time. Is this thing ever going to work like expected?

    After all this time, I expect it to fail all the time. My Surface never fails to meet these expectations :)

    Month later I am still highly frustrated by this.  My Surface, purchased about 6 weeks ago, continues to suffer from this bug.   Half the time I pull it out of the bag hot with battery drained.    The update meant to fix this failed to install.  All other updates to today have installed, and I also manually installed the latest driver pack from the microsoft web site dated April 29 and I have turned off Hello.

    Still no luck.  It means I can't depend on the Surface and may have to give up on it.
