To sum this up:
The phone shuts off at 3.3V on the battery
The battery manager you refer to is not that accurate, it says 0% at about 3.6V
In mine i use a custom "script" for QBW

Code:

hal-device | grep voltage.current | awk '{printf "%1.3fV - %3.0f", $3/1000,($3-3300)/9}{print "%"}'

with this "script" the phone turns off seconds after it shows 0%

At 3.3V the battery is about empty, if you where to use it after this it would be a matter of minutes before it would hit 2.0V and that will kill the battery completely.
But luckily the phone has a batt manager that shuts it off at 3,3V, and the battery has a circuit that shuts it off at 3.0V.
