iOS 11.4 battery drain

My iPhone 6 was working perfectly fine until I updated to iOS 11.4 and ever since I did that my battery is draining rapidly even without me using it at all. I used to go a full day without charging it now it may last half a day. I am just wondering if something got turned on with this new update that I have to turn off to save battery life. It is just weird I have not done anything other than update the iOS and now this happening. Any help would be greatly appreciated.

I have the same issue.

When I look at my battery performance, it shows that the personal hotspot on my phone is being used, though I have never turned it on. I have to keep charging my iPhone every 2-3 hours now.

Unfortunately, it's no longer possible, as Apple has stopped signing 11.3.1.

It´s a bug. If you use a 5 GHz wifi network battery consumption is very very high.

Well my iPhone 6 and I hop they fix this ASAP and not have to wait weeks for a fix or even jump to iOS 12

"They" are going to fix it for sure I think, we can bet ;-). Problem seems to be in 5GHz Wifi.. going to check it today.

How many of your unaffected iOS devices are iPhone 6s and/or iPad Minis, connected to a 5Ghz Wi-Fi network?

Well hate to tell you guys that the problem came back. So let's wait till Apple find a solution.

Must be a slow news day. There are similar articles after every iOS release since 2007.

-Update-

Toggled between 2.4GHz and 5.0GHz...

For me the 5.0GHz is the culprit, on 2.4GHz everything is fine ..!
