Seeing that this update is out for everyone now I won't have any fear of any soak test repercussions. I had previously deleted some of my posts here. I've had the update for several days now. A lot of changes to app permissions is nice. It's nice to have these features but I doubt I'll use them. Bummer no wifi calling YET. Easier access to volume controls is a major plus for me. As far as battery, I'm not seeing any better numbers at all. Originally I got excited cuz I took my phone off the charger at 630 and at 910 I was still at 100%. Android system has crashed a few times but I didn't notice any issues otherwise. Phone runs very smooth but it did before 6.0. I initially had some wifi connection issues but they resolved themselves. As far as speed throughout, feels about the same. I think it's safe for all to download the update at this point. It's been since Saturday for me and I'm happy with it overall. Also for those using Nova Launcher as I am it works just as good as before.
