iPhone 6(S)/Plus All of a sudden, battery life is terrible - iOS 11.4?

Well I just now noticed after this update, it turned on background refresh for Wi-Fi. Previously I had background refresh completely off as my device is only used on Wi-Fi at home (No SIM). So that's a change I didn't see until about an hour ago. I see no change in battery drainage with 2.4 VS 5 MHz on Wi-Fi.
I'm about to turn off messages in cloud and see if that makes a difference.
Honestly the device acts and functions the same as 11.3.1 for my usage, just with more battery drain. It's bizarre.
P.S Haven't seen battery glitch again.
Went to bed last night at 80% and 8 hours later phone was dead. So it’s not just a reporting issue.
Oh and even running battery saver all the time, I'm losing 1-2% in about a minute. This is really something.
My device has all background off, privacy off, airplane mode, turned off messages in cloud, and nope.
This has to be an app and I'm thinking is is one of Apple's as battery usage shows high for things like news 7%, home and lock screen 3%, and settings 1%. Never seen that before.
This is most odd - my phone's been unplugged since around 5:30 this morning (it's a shade before 1PM here, now) and i'm at 76% where it's been moderately used - so ~25% in 330 odd minutes...
I wonder if it's anything to do with you not having a SIM whereas I do. That said, I've not left the house today so I've been on Wi-Fi all morning.
Certainly sounding like a runaway. Have you rebooted today at all? Every now and then I seem to get what I think is a runaway on my watch that'll seemingly cause it to drop from 100% to 0% in 6 hours, one reboot later and it's happy as it ever was...
I don’t seem to be having the problem anymore, or at least I haven’t had trouble for a few days now. I don't think it's Messages in iCloud, as I never had it enabled in the first place.
I let it completely die yesterday, I've changed a few settings today. So I'll try a hard restart. Then I'll report back in 24 hours. My fix won't be for everyone as I pretty much disable everything.
On 11.4, I get about 30% battery drain overnight if I leave my phone connected to WiFi. Since I’ve stopped leaving it connected to WiFi overnight, it’s perfectly fine. Hopefully this gets resolved though.
I might have to just turn off WiFi at night when I'm not using it. I have another phone, so that'll be okay.
I doubt a cheap usb cable can damage an iPhone when a device like a "usb killer" can't damage an iPhone.
Well after reading this entire thread,that red circle with the # 1 inside it,next to Software Updates on my 6S+ will stay right there until a fix comes out.
My 6S drains badly too after this update. Really miffed about it as at the end of last year I had three months of poor battery life before an update solved it. Now I’m in the same situation again!
Picked my phone up yesterday and the battery said 10%, and when I started using it the screen went black and I had a loading circle in the middle. The battery was in fact completely dead despite sitting on the side for most of the day. Poor form indeed, sort it out Apple.

Since my 7 Plus has no SIM currently, I can't tell if it would drain as bad on cellular but after over 15 hours on standby (in airplane mode) it's still at 100%. My guess would be that while wifi is on, there is some system app or process (That might not show up under battery usage) that is killing our devices very rapidly.
I might have to move my SIM from my V30+ to the iPhone to see how it fares on standby with cellular.

Its Apples forced obsolescence I’m afraid, because they couldn’t source us 6S users to upgrade our phones, they are now doing it with iOS 11 draining the battery. Mine was fine before iOS 11.3, now it drains so so fast no matter I’m doing, I’ve had the situation where I had to reboot it a couple of times and so the phone then rebooted itself and went into to throttle mode... it’s also switches off at 40% and gone into throttle mode a few times... all whilst reporting my battery life as fine..
And thanks to Apple, I have to have THERE battery put in for all the software to work properly.. and if I can’t go to the nearest store, about 60 miles away, and get it changed the same day, I won’t bother.
I was hoping to change to a new X style SE, but who knows what’s happening with that, and all the other phones are too big or overpriced, an 8 doesn’t feel different enough.
So alas I’ll have to get the battery changed, and feel as though Apple has forced me into it all the while, and in my family I’m not the only one who feels like this!
I think the fact in my experience, that on iOS 11 even with throttle mode engaged, battery life is far worst then under iOS 10. It shows how they are forcing you to give them more money if you want an iPhone.
Now I’ll pay the £25 for a new battery, but it’s the fact I’ll have to go without a phone for a week or 2, or spend time and money doing a 120 mile round trip twice to get it that peeves me off!
Do the stores now have 6S batteries in stock? In the U.K?

Intersting: I hit 50% after about 11 hours yesterday and never left my WiFi connection, so I'm guessing that whatever this is, it's not global to all 7 plus phones on iOS 11.4, but rather more specific to some to many.
I was having battery drain problems on my 6S immediately after updating to 11.4. This a brand new 6s with a brand new battery. (got it for under $300 which I thought was a steal 
)It was draining from 100% to under 10% overnight for the first two nights and then went back to normal. It happened 2 or 3 more times after that and has since been normal for the past week. My issue seemed to have resolved itself for now.

Same for me. It makes me wonder if the phone was indexing or something. It’s been almost a week since I had problems, and I really haven’t done anything to fix it.
