Updated two days ago and it's a disaster. First of all, why are they cramming iOS with a bunch of sheeit nobody wants? Secondly, I used to be able to have more than two apps open without my phone battery draining, now if I have more than two open I can watch the battery percentage go down. No idea if this is something that can be fixed or not, but using a power bank only works if you don't have more than two apps open. At least my phone isn't bricked though.
