Battery life of Surface Pro 3 with Windows 10

I'm loving Windows 10 with my Surface Pro 3.  Windows 10 still has some kinks to iron out and their new web browser, Microsoft Edge, is far from ready to be your default brower, or even secondary browser, but its been a great upgrade for my SP3.  More on the reasons why Windows 10 is great in another article.

Tips

• The new "Battery Saver" feature is easy to activate (and de-activate) through the battery icon on the taskbar.  It does not appear to impact performance appreciably and does seem to extend battery life considerably.  
• See which apps (Modern or Desktop apps) are consuming power by checking:  Settings > System > Battery saver > Battery use.  E.g. is "Mouse without Borders" eating my battery?  
• Change the time it takes for your computer to hibernate to a reasonable number.  After upgrade to Windows 10, the setting was to hibernate after 4 hours of inactivity, which is ridiculous.  See:  Settings > System > Power & sleep > Additional power settings > Change plan settings > Change advanced power settings > Sleep > Hibernate after.  The SP3 takes about 10-15 seconds to come out of hibernation  
• Is the "connected to Wi-Fi while asleep" feature useful?

Findings

• Watching online video consumes the most power so far
• Film & TV app uses less power than VLC Desktop app 
• Using Adobe Flash Player does not appear to consume any additional power for Google Chrome
• Microsoft Edge seems to be slightly more power-efficient than Google Chrome for watching YouTube video
• Windows Store (i.e. Modern) apps may be somewhat more power-efficient than Desktop apps

Estimated battery life for various scenarios

• Offline reading on airplane - 7-8 hours
• Offline movie watching on airplane - 5-6 hours (using Film & TV app)
• Online video viewing - 3.5-4.5 hours (YouTube fullscreen on Microsoft Edge)
• Web conferencing - 5-6 hours (e.g. WebEx)
• Coffee shop/library "work" scenario - 5.5-6.5 hours (web browsing, writing, streaming music but not watching video)
• Participation at conference - 7-8 hours (occasional online use)

The last three scenarios were tested with the Battery Saver feature turned on whereas the other scenarios were not.  Therefore, with the Battery Saver enabled, the estimated battery life may be even higher for the first three scenarios.

The SP3 can be powered by an external battery (pictures and details of equipment in another article) but in a situation like a conference, where more weight is an extreme burden, the SP3 is able to last the entire day without relying on another battery.

Another potential way to save power is to disable calendar notifications.  Calendar notifications turn on an otherwise inactive screen to display a reminder; really, do you need your SP3 to display a reminder when it's probably happening on your phone already?!?  Have not measured power savings by doing this yet.
