Just bought a iPhone 8 and the first thing it did was try to download 11.4.1. Was wondering how battery life is on this update since 11.4 had a bad drain. I'm currently on 11.2 something and battery is perfect so far and don't wanna risk it so early 
Update from 11.4 to 11.4.1 has caused major battery drain issues. Battery is going dead while phone is just sitting on counter locked at a massive rate.
Gonna bite the bullet and update it finally, was gonna wait until iOS 12 but oh wellMine works great, has had it for a month, running the lastes iOS 11 11.4.1 and lovin it.
The phone wasn't setup as new, restored a backup and its full of apps.
Don't have any google or facebook apps on it other than youtube.
iOS 11.4.1 seems to be very stable and has been on every phone I have updated, and the whole family is running a mix of SE, 6S and 7.
