I have read most of the threads regarding iOS11 and battery life. But, I was curious if there was a greater preponderance of battery life issues that happened to be model specific.
The battery life on my 6+ is fine. I am nowhere near a heavy user. Just normal use, mainly use Safari, Whatsapp,... And the battery sure is enough for one day use.
This is my normal one day use. 13 hours standby time, about 5.5 hours on screen time, and still has ~40% battery remaining when I back home. More or less the same as iOS 10.3.3.
