How do people test the battery run time for their laptop or tablet?
I have the device streaming youtube.
I recently bought a used Surface Pro 2. The battery is good for
five hours streaming youtube!

Charge it and then create 100% load on CPU, HDD, GPU. The check after
what time it reached a critical level.

Is that a realistic test? I see the youtube streaming as a good test
of how long the battery can operate under normal conditions.
It used to be that people would test the battery by playing a
DVD movie.

If you want to know how long it operates when the system is being on
full load, then yes.

It depends on what you like to know. If you like to know how long it
lasts of you only run a text editor, low screen brightness and no
GPU/CPU activity, then you need to test with these circumstances.
