    I noticed in the last days that my Macbook Pro Retina mid 2012 suddenly lost 1-2 ours of its battery health. At least I think so. I used the Battery Health app and I noticed that in its 'Time Remaining' info tab, 'Current Usage' is approximately two hours less than 'Internet Browsing'. Is that normal? I guess it is not since I checked and I only have Safari running in the background. It should be the same,right?

    I provide you pictures and links with some documents,which include my processes running,from the activity monitor utility. Personally I didn't notice anything weird but I need some help in order to exclude that it is a software issue. The thing is that I recently took the macbook for service for a different reason and apart from a general diagnostic test they also checked the battery,as I asked, and everything proved to be ok.

    In case you need any other information just ask me. Thank you in advance!

    It's not unusual if your discrete GPU is being used.

    Can you be a little more elaborate? Looking at the energy consumption in the activity monitor (you can check the pdf document), I don't see something that consumes a lot. Apart from Safari obviously, but this is the browser to surf, if we assume that current usage should be close to internet browsing.

    EDIT: I also did a PVRAM reset as I read somewhere, and I lost an hour.. Now I am in 4 and something.. This is weird?
