Question: iOS 11.4 Battery Drain!

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

Is this still fixed for you? I’ve tried this on all three iPhones but to no avail. They still run empty about twice as fast as usual. Especially at home I see about 10 - 15% drop per hour.

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.

Yes, Apple stopped signing 11.3.1 a few days ago. They screwed a lot of people by not issuing a fix before stopping a restore path. I’m so glad I was able to go back to 11.3.1. My phone has been working great after the restore to 11.3.1. Just not sure what the future holds now...

Ah.. well that’s annoying, ever since I updated to iOS 11.4 about 2-3 days ago my battery has been draining significantly like it goes from 90% to 40% in the space of like 2-3 hours when not in use and was on airplane mode to avoid the battery going down and it’s driving bf me crazy to be honest, it’s a shame that they stopped allowing going back to iOS 11.3.1

Same problem here it’s draining super fast. I look at my phone after it’s sitting for a couple of minutes and it’s down 10-20%. I hope apple sees all the problems with the batteries and has a update fix soon or I may just change to the dreaded android which I hate but can’t use my phone this way

I have somehow fixed this problem, I force shut down my iPhone 7 holding the volume and sleep/wake Button which restarted it and now doesn’t seem to be draining as fast and seems to have returned to normal I assume.. so maybe any of you could try doing this ? Maybe ?
