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.
Thanks for posting this...so far my phone has stayed up long enough for me to reboot the phone (leave it off for at least one minute).
Powered it back on and went straight to ESPN and was able to browse normally...dangit, Astros are already down 5-3, where as before it would immediately shut down. Opened up a few more tabs and still no shut down.
Battery went from 100% to 96% in a span of 8mins...
Apple store employee told me if the Apple device you have is near the bottom of the list of Apple products eligible for an iOS update...don't update. iOS updates are for the newer products. That's why 6s, 6 and SE phones are suffering the battery problem and the newest phones aren't having the problem or very, very few. Apple wants more money and through updates actually makes older models obsolescent forcing customers to spend more on the newer phones.
Thanks, that did not work for me iphone6S. Only thing that works is changing Wifi to 2gz
How in the world do you the downgrade when Apple is no longer signing the previous release??
iOS 11.4 Battery Drain!
