Question: iOS 11.4 battery = disaster! Handoff is culprit?
Hi, I have iPhone 6s, my battery life has been reduced by ~50% with iOS 11.4! Without any change in my usage pattern.
My battery health is 96% (device is just 6+ months old). I used to get from 100% down to a single digit in a day+ (30-35 hours) with iOS 11.3.1, now it takes 15-16 hours! And my daily usage pattern hasn't changed a bit. It started immediately after installing 11.4 two days ago (official version, I do not install betas).
I suspect handoff between iPhone and my Mac is the main culprit. Today took my phone off the charger in the morning at 100%. After 11 hours at work and commute (no handoff there) I was at 65%-70% when I got home. After 2 hours at home, working mainly on my Mac (very little on the phone itself), I was down to 50%. After 3 more hours (again, barely touching the phone), down to 7%. What is that???!!!
I am sorry, but this is a huge FAIL. This software "upgrade" has downgraded my battery life by 50% or so. It is unacceptable. Give me back iOS 11.3.x!
