My battery life on my 6s is 96% and my battery drain is beyond annoying. The other day I was getting my sprinklers winterized and had to cycle through each zone with my app (I have a Rachio), within 20 minutes it dropped from 80% to 19%. Come on Apple, this is ridiculous. IOS 12 has some kind of bug.
Got a tip for us?

iOS 12 is eating my battery!!!

Drain and charge seems to make matter worse. I don’t know how but it seems like it.
Unless apple comes out with a solution otherwise My next phone wont be an iPhone.

Same here, my 7 has been pretty bad since the update with battery life. I will literally watch the battery drain in chunks as I use it. Like it jumps from50% down to 47% at one time.
The drain and usage are abysmal atm , i can't remember a time when a Max/Plus device had such pitiful battery life. It's all great for calls/browsing but when you try to play some intensive games and it gets hot I see it double down on that drain.
Doubt they can fix this and im already missing my S8+.

You can try updating to the 12.1 public beta. I’m on 12.1 b2 and battery life is great on my 6s. One of the things I’ve been doing for about a year however is keeping low battery mode on almost 24x7.
Maybe a placebo effect
But I used to charge my phone with iPad charger as it charges very fast but I’ve seen it drain it fast too.
Last 3 days I’m charging with the regular 5W charger and the battery lasts longer.
I’ve not disabled screen time or disabled Background app refresh.

It's not the 85%. That's not normal at all. 85% is fine. Can be iOS 12, but battery health being at 85% is no explanation for it dropping like 17% in 3 minutes like it did in your case.It's on 85% according to the Battery App, but it's been working fine up 'till the upgrade to IOS 12, then suddenly I get extreme drops for a while.
It's steady at 34% now.

I can definitely say factory wipe, clean install does not work. iOS 12 drains battery very quickly comparing to iOS 11.4.1. I think they will improve it with point updates but right now it is pretty bad.
iPhone 6s with battery health %92 only gives 2-2.5 hours screen on time. I am pretty sure it was much better during beta period and yes I did clean install on the first day of iOS 12 release.

What does the battery in preferences show as to what apps are using the most battery? That kind of information could be helpful. If any show a lot of usage I'd force kill that app or apps and then do a restart and restart those apps and see if that makes a difference.
My experience is that sometimes apps don't do well running during an OS update. May not be applicable but worth a try maybe

I can't help but wonder why do iOS updates impact battery life so much. It's simply unacceptable. I'm getting 7-9 hours on-screen usage (depending on condition - brightness, usage, Wi-Fi or cellular) with my 6s with 93% battery health on iOS 9.
Nothing unusual except WhatsApp background activity. I am waiting iOS 12.0.1 to clean install again. But I did notice that .0.1 release took too much time. It is 3 weeks after the first release of iOS 12.0 and there is still not .0.1 update. I am very happy with iOS 12. I have zero issues with performance, UI or smoothness except for battery life. I think that's why first time ever .0.1 still not there. Because there is not observable issue with iOS 12. Battery may seem very subjective so that Apple did not see enough reports. I sent a bug report last week, still waiting for answer from Apple.
That can't be. I did a clean install and my phone is perfect.
Was this clean install done on the phone itself? Did you erase all content and settings?
You need to restore it using iTunes and then select "set it up as new".
I was getting phenomenal battery performance with iOS 10.3.3 on the same device. iOS 11 broke all the things, iOS 12 is worse for me (at least for now).

I did DFU factory install and I have selected "set it up as new" as I always do. Maybe the main cause is WhatsApp which uses a lot of background energy while I am using WhatsApp for Mac. But I see background activities for other applications as well. So I think there is something wrong with iOS 12 background mode.
I understand people are suggesting to turn off screen time, don’t use fb and WhatsApp etc but that won’t fix anything.
This is my usage after taking off charge 11 hours and still on 50%. I Always use backup to restore since original iPhone , using iPhone X with battery health 98%.
I know battery took dive after iOS 12 release but Turning off features won’t help in my opinion, this need to Fix from apple side, I don’t kill apps in background except fb and gps apps.

It can depend on what the issue is. In some cases there can be apps of features that aren't doing something right for one reason or another and are contributing to it all.
New phones + new iOS (again) = as usual a perfect storm
It may or may not be an app has rounded with OS. Most apps don’t really test until the released version.
In last 16 years of Mac OS X and now iOS there’s never been a rollout that was ready for prime time. Not until 4-6 months of work to update to .2 or later.
And time to learn and use latest compiler tools as well.

I did 3 clean installs using iTunes on my iMac (setting up as new and forgetting about my local backup) I let it settle down for about 2-3 days and the problem persists (iPhone 6s 64GB) Performance wise is like a dream come true, but battery life is around 25% worse in my case. I have tried once to run my battery flat (that has absolutely helped in my 2017 128GB iPad...) But in the case of the iPhone, I noticed (after running flat and shutting down itself) that the graphic showing that you have to plug your phone would not appear and the phone itself would try a continuous reboot...I wonder if that has something to do with it all or if I should try to deplete it until the plug in logo appears. I know depleting these batteries is not a good thing 
iPhone 7 Plus
Battery is draining without much usage
It was not like this in iOS 11 , regretting for updgrading to iOS 12 without checking the reviews

I think you need a new battery. I have an X and I'm not noticing a big difference in battery life between iOS 11 and 12. It can't be the OS itself. After a clean install, you're left with a fresh version of iOS. It's either a rouge app that you installed, or your battery is acting up.
