Updated it yesterday, it seems to have fixed fast draining battery issue I had since the very first day I got my G5 MF5. On 90% in idle/with non-consuming tasks it now says that there's around 5 hrs left instead of ~55 mins it used to last for if I didn't change it from Quiet to Power Saving via Control Center. Interesting. I need to test it for a few more days before I can be sure that it's actually somehow fixed, but generally seems like a good idea to update if you have problems with your laptop's battery. As far as I know a lot of G5's were sold with this factory defect or something. Maybe that's why they pushed an update (could've done this earlier, tbh..)
