This is the second time that battery is causing issue. Initially after I bought I gave it to apple service and they reinstalled OS and suggested VirtualBox was causing the drain so I did not install it next time around.
Now I installed Intel HAXM and battery again fell back to 3-4 hours. I have removed Intel HAXM and still the battery is giving 3-4 hours.
Activity manager does not show a rogue process, most processes are under 1%.
Can you help me detect why the battery is being drained or how to find the cause?
EDIT looks like http://apple.stackexchange.com/a/6301/53842 might have a clue. I did not check on All processes in activity Monitor filter. It was
taking more than 80% CPU. Now the battery is slowly coming back to show more time.
Question part 1> Are virtualization software generally drain life on mac? Or is there an alternative?
Question part 2> If parental control service is causing drain then how do we use parental control feature without draining battery? Many other posts suggest to delete and restart and then use it again.
