Several Microsoft Surface devices suffer from battery bug - drains battery overnight

Several models of the Surface Pro 4 and Surface Book suffer from a battery bug causing the battery to drain fast when in standby. Users of the affected models complain on Reddit and the Microsoft Forums. The devices also become hot when they should be in standby mode, however it appears they don't properly go in this mode where they normally would consume a lot less energy.

When the devices are put in hibernate the issue is resolved but there appears to be a serious issue when the affected Surface models are in standby. They are about fully discharged when in standby mode overnight.

The possible culprit is a faulty graphic card driver causing it to not go properly in standby. Another mentioned possible cause are the drivers of the infrared camera used for biometric authentication by Windows Hello.
