Hello to all, i have 2 iPhone 5s and 6+. 5s is on latest iOS 11.2.1 and i am getting very bad iOS experience on it, battery draining, lagging and very slow performance. But my 6+ is still on 11.2 which is not bad at all like iOS 11 previous updates. I just want to know that should I update my 6+ on iOS 11.2.1? Anybody who update its 6+ on 11.2.1 and share their experience with me.
