My phone is a Desire HD.
MIUI redesigned the Battery use screen after you touch the graph but awake time is completely wrong.
As you can see in the pics my phone is on battery for 1 hour 13 mins and Awake time is completely blue so it thinks my phone is awake 100% of the time.
But in the second pic you can see the true awake time from Battery history: only 1.7%
