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)

    Hmm, dinner and a movie. From 8pm to 11:30pm it went down 8%. Stupid connected standby. Has anyone tried this way to disable it?

    Q. How do I disable Connected Standby on a device?

    A. If a device supports Connected Standby, you should take advantage of that capability. Only modern applications that are registered can send a limited amount of network traffic at a scheduled interval, which means Connected Standby generally offers only benefits. However, if you want to use basic sleep instead of Connected Standby, you can disable the feature as follows:

    1. Start the registry editor (regedit.exe).
    2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power.
    3. Double-click CsEnabled and set to 0, then click OK.

    I'd like to actually get decent battery life from my device :P haha. 

    But, thankfully, this time it didn't get warm at all! Before this flash, it would be warm and lose 5% every 5-10 minutes. Now it lost 8% over a period of nearly three and a half hours!

    I'd like to be able to start with a Surface pro image prior to the Threshold 2 update. I should have saved it. Prior to TH2, my drain rate was better, only 550 mW per hour, as opposed to the 1500 now :(

    I would notice the same after a full charge. The first standby session shows no drain. The next goes back to usual 4% for me :(
