Why and how do I fix the new issue with battery drain after updating to iOS 11.4? Before updating, might loose as much as 10% overnight on my 6s. After update it now drains completely from 100% over the course of the night to the point that it won’t start until I plug it in and let it charge a bit. iPad air2 drains much more as well, but not to the same extreme.
iPhone 6s, iOS 11.4
My iPhone 6S was loosing 30 - 40% overnight on standby after updating to 11.4. I tried virtuall all recommendations over a 4 day period. I finally gave up and rolled back to 11.3.1. Now only drains 0 to 1% overnight. Pretty clear apple needs to step up on this one.
Happy to say that the last update solved the problem. 11.4.1 stopped battery draining on two 6s so far.
Exactly the same here - just shows how good Apple are - they fixed a problem they didn’t even know existed ......
Sadly, mine is still not fixed even updated to 11.4.1
Neither was mine or my spouse's. It is a tiny bit better, but I still have to switch back and forth between wifi 2g and 5g so battery doesn't drain as quickly.
iOS 11.4 Battery Drain!
