Battery life Macbook 13 Retina mid 2014
Battery life is heavily dependent upon how you use the system. Things such as leaving screen brightness at maximum can have significant effect on how quickly power is drained from a charged battery. Applications such as running guest operating systems inside of a virtual machine can be I/O- and CPU-intensive tasks that will also reduce the longevity of a charge.

If you're running VMs with regular screen brightness, I'd say 5 hours of battery is about right.
