Comment 131 for bug 1480877

FWIW, I see the weird new behavior on every test with wifi enabled, even when the screen is on and the phone is actively doing something. For example, while playing music:

... versus how it looked before:

But in flight mode, both graphs are a flat line barely above zero:

So, it's not just while sleeping; it's any time wifi is enabled.
