sorry, I know it's not the correct place but I have no chose
as you know apple mac pro has battery power up to 7 hour because it's use OS of apple
we know that all other Laptop products can have up to 3 hour in standard battery because Microsoft OS take to much to run it
my question is If I install vmware fusion on mac and create VM with Microsoft OS, Is it will effect the battery of my mac laptop or not ??? can I use it up to 7 hour or up to 3 hour ??
As long as the Windows VM is not actively thrashing the disk it really should not impact the battery performance -
I can tell you from my own personal experience with my MacBook Pro that one will not get the rated battery life when running virtual machines solely on battery power as they tend to be more CPU/GPU and HDD I/O intensive then more traditional Mac Apps like using iWork or Microsoft Office while on battery only. Also running Multimedia type apps will reduce the time between needing to recharge the battery.
