Snow Leopard -> Lion : LOSS 4 HOURS OF BATTERY LIFE
Hi, since OS X Lion, my Macbook White (late 2009), had some battery life problems.
Mac OS Snow Leopard (10.6.5) ---> 7 hours of battery
Mac OS Lion (10.7.3) ---> 3 hours of battery
For the same using...
Apparently I'm not alone to have this problem.
An idea ?
