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


New Member
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?

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