How to fix the battery drain/connected standby issue in Windows 8.1

Are you experiencing high battery drain in Windows 8.1 during connected standby? Then this fix is for you, I went from losing 10-30% in battery every night to losing 2-3%.
Here's how you can do it, you will need to activate Bluetooth in Change PC Settings ->PC and Devices->Bluetooth, and stop using the airplane mode, just shut off your WIFI instead. That's it!

I found this solution/fix on the answers.Microsoft forum, High battery drain using Windows RT 8.1, UART V2 Driver listed as - Microsoft Community
I guess that's why I haven't had the battery drain issue - I leave Bluetooth on because I use it regularly and haven't had battery life issues.
