I'm gong to remind everyone in this thread that if you use the default sleep settings make certain all the apps are closed if you're having serious battery drain.
No, it doesn't. If you were using hibernation it would. The default settings allow the Surface to perform background tasks while sleeping if WiFi is on. That means everything and anything that is open will run nearly as if it was awake. Of course a lot depends on what the app is doing. It's called Connected Standby, which is not the same sleep state you might have had in the past with a laptop.Thanks..not sure if I am understanding your message..doesn't closing all apps before putting the computer to sleep defeat the purpose of having sleep? Or..Are you suggesting that we try to see if it being cause by a certain APP that is left open?
Seems like you should try turning off WIFI scanning during sleep and see if that does it for you. There is an option for that in the setting menu. Your culprit is much different than mine. I've got the Intel Graphics active over 90% of the time. Thanks for posting.
For me, turning off both of the WiFi during sleep settings did nothing to help the battery drain during sleep.Close. You can leave the apps open if you change a setting to turn off WiFi during sleep. With that set and a few other tuneups my battery loss is less than 1/2% per hour sleeping.
Having to close all apps before putting the device to sleep really defeats the entire point of having a sleep mode. The only reason to even offer a sleep mode (rather than a "screen off" mode like you are describing) is so that you don't have to close all of your apps while saving battery life, as in, I want to resume where I was a couple minutes or hours from now while saving battery as I would on any other device, including previous Surface Pros. From what you've posted, you've customized, tweaked, and removed apps from your SP4 to get great battery: awesome for you. I and many other users, however, just want the thing to work well out of the box as any good consumer product should without having to troubleshoot, research workarounds, and edit registries.I'm gong to remind everyone in this thread that if you use the default sleep settings make certain all the apps are closed if you're having serious battery drain.
