Hi all.
I’m using an iPhone 6s+ and currently running on iOS 12.
May I know, from those who are on iOS 12.3.1, how’s the performance of the phone?
Should I stay on iOS 12 or is it all right/recommended to go up to iOS 12.3.1?
I have my reservation on the phone’s capabilities to run on iOS 13 smoothly, so before the window to update to iOS 12.3.1 closes on me, I thought I put my question out here.
Thanks in advance, for your reply.

Battery capacity was one of the primary reason I went with the iPhone 6s+, when both the 6s and 6s+ was launched, back then.
Noted with thanks on the sharing of your phone usage experience with iOS 12.3.1, mate.
