Full performance mode isn’t necessary for all tasks and Microsoft is now working on a new feature that would allow you to quickly adjust level of performance. Called Power Mode, the feature will significantly improve the power management feature in Windows 10.
Hopefully Microsoft will make some other changes that would further improve battery life or power management. The feature is now included in the new Windows 10 build 15014 that is currently available for Windows Insiders. Whether or not it will be included in the Creators Update is unknown.
