Is anyone experiencing decreased battery life under DP4 compared to DP3? I am running the OS on a MBP 2010 13 with a Momentus XT hybrid SSD. Under Snow Leopard, I was experiencing issues with poor battery life with the XT. Then under DP3, battery life was greatly improved and I was getting 7 or 8 of battery life similar to the OEM 5400 RPM HD. Now under DP4, it appears that battery issues have resurfaced. Battery life has been reduced tremendously and the battery timer is constantly recalculating... Anyone else noticing decreased battery life under DP4 on the Momentus XT or on any other system generally?
