Surface Book: problem with discharge rate, is this normal?

[winstondon]

Hey guys,my surface book with i7 16GB 512GB and dedicated graphics seems to drain battery much quicker than advertised.

Just browsing internet, with battery saver and screen brightness at 25%, no graphic/ image processing. It's been on battery for about 2 hours, and almost 50% of my battery life is gone.

After monitoring it closely with BatteryMon, I got a discharge rate of ~16 W sounds like the fan is running.

What are you guys getting?

I am seeing this as well. Been using it for two days now and my SP3 had better battery life!!!

It takes 48-72 hours for Windows to finish indexing and optimizing the installation which impacts the battery life....
