Windows Hello may be causing battery issues

Windows Hello can be used to login to Windows 10 devices, but it seems to be draining Surface Pro 4 and Surface Book batteries rapidly.
Windows Hello, the biometric login system for Windows 10, appears to be the cause of a major battery drain issue for the Surface Pro 4 and Surface Book.
One user took to Microsoft’s official support forum to detail their issue. “Through lots of trial and error, I think I found the problem. It’s Windows Hello. Turn it on: get 5 hrs of connected standby. Turn it off: get 87 hrs of connected standby,” they wrote.
Other users responded to say that they were having similar problems. “Will someone from Microsoft please comment on how the devices were sold as having a sleep mode which does not work? It uses just as much battery while 'sleeping' as it does during use. Mine drains at over 10% per hour while asleep," one posted.
If you are having similar issues, try turning Windows Hello off and see if that makes a difference. To do so, go to Settings > Accounts > Sign in options.
If Windows Hello is the root of this problem, we should see an official fix relatively soon. But in the meantime, switching Windows Hello off could significantly increase the amount of time you can use your Surface Pro 4 or Surface Book for.
