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 6s was having the severe battery drain after installing 11.4. Had to charge every 6 hrs with moderate use. blocking my home wifi to the 5g band helped a bunch, was back to near normal. I did a Network Settings reset and afterwards the 5g connection worked much better as far as near normal battery drain. 2 days ago i rejoined the Apple Beta iOS tester group to be able to download and install Public Beta 2 of iOS 11.4.1. Having run that for 1.5 days now, I can say my phone is back to normal. Yesterday i had 19 hours of standby and 3.75 hrs of usage and was still at 45% when i went to bed.
Beta firmware has its potential downfalls, so only choose this if understood. My phone is not a critical or business related device so was able to do this for my situation without fear.
Did same as u but still draining
wondering if anyone has a real fix. Tried full restore 6s twice but each time it reinstalled 11.4 so it did nothing, and problem lingers. Found battery drain when on wifi like others have said.
You are correct that Apple stopped signing 11.3.1, so rollback is no longer possible.
Thanks for that. It's too bad we weren't made aware of that before downloading the update that has made our phones useless.
Good luck with the Samsung. I had a Samsung before the iPhone6 and I had three months of headaches with it. I got rid of it to go with Apple. I was really happy with my iPhone until this os11.4
Exactly the same answer and result as I.
Same.
Nope, not just US or UK - add Spain to the list
My 6s still refusing to hold a full charge for more than 6 to 8 hours, with no use of course
An easy one - you can‘t
Thank you.
You're welcome.
Even i have turned off the wifi, background app refresh and airplane mode, my battery still draining fast
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
Same here. Obviously tried soft reset etc. Battery drain is extreme on two 6S. On my work phone, an old iPhone 6 battery seems to be unaffected. But both my wife´s and my 6S are affected. Haven´t upgraded the kids 6S yet, awaiting a solution.
Woke up this morning, read some news and took a game of Clash Royal. From 100% to 80% before breakfast. Haven´t touched my phone since I arrived at work, it's now, around 11:00 on 51%. Will have to charge it before I go home.
iOS 11.4 Battery Drain!
