Hi
A lot. Mirko posted some measurements I did some time ago after
implementing suspend:
State | Power consumption |
- --------------------|--------------------|
Under full load | 160 mA |
Idle black screen | 94.5 mA |
Idle white screen | 92 mA |
Idle colored screen | 104 mA |
Display off | 52.5 mA |
Suspended | 9.8 mA |
