I have an iPhone 6 running on 11.4.1 and I wondering if anyone here is also still using on iPhone 6 but on the latest iOS 12 it's spec'd to handle. I'm not really having any issue with the phone but it is a bit sluggish at times at certain apps have been killing the battery (which claims to be at 95% of its capacity). I'm the type that doesn't want to buy a new iPhone until the phone straight up does not work so I'd like to get the most out of this 6. So, what do you think? will updating do more harm than good or should I go for it?
