Sheeeesh! 90% Ouch!
Mine dropped last night as well. Down to 97%. September can't get here soon enough.

It was 92% on Monday, checked it the other day and was surprised to see it drop 2 points. Hopefully it gets a little better with iOS 17 in 3 days!!!
Is it September yet?
You have to have Pro Max...? Cant get beyond 4 hours of usage overall on my regular Pro
Roughly 6 month intervals on my iPhone 13 mini. Gone from great battery life to absolutely shocking, ios16 has been a disaster on this device (currently 16.6beta) and I do all the power saving 'tips' you can name; darkmode 24/7, reduced white balance, no haptics, airplane mode during the day...the list goes on. I have also got rid of social media apps (mainly instagram/youtube) as they were sucking up loads of my time and yet it just gets worse. Tempted to jump on 17 and see what happens or just do a fresh, no backup restore, install of the latest 16 version; I am at a loss.

I do confirm drain for no reason with my 14 pro. After the 16.5.1 battery consumption is there but for no obvious reason. i suppose it's from the new firmware. Before that i used to get 2 full days of usage and now 1 max....i tried everything but without success 
iPhone 14 Pro, iOS 16.5.1 battery is draining like a crazy thing here as well.
Same thing with my iPhone 13 Pro Max. It used to have amazing battery life, i've never had a phone that lasted so long but since iOS 16.5 it's trash.
I'd say i'm getting half of the battery life i used to get. I do understand battery health went down but i only lost 2% after updating to iOS 16.
I think it is irrelevant of the battery because for me it literally happened from one day to the other after the update. Weirdly the standby time of my iPhone 12 improved and destroyed the 14 pro....
My 12 mini is down to about 16 hours per charge even with low-power mode switched on. Before 16.5, I was getting up to 40 hours per charge. Planned obsolescence at its finest.
I ve realised today that the drain is more obvious while connected to Wi-Fi … how on earth is this happening ? Without any change in setup or app or anything and only the 14 pro affected…. And I truly believe is the 16.5.1 since even in the battery’s statistics there is no app consuming weirdly and zero background activity… the battery drops when I am not using the phone at all …. Suggestions ? Thanks in advance
I found the solution at least for my 14 pro problem but I am sure that this has affected other users as well. Since the day of the new update I be been experiencing standby battery drain. I deactivated the call after serious crash option inside the emergency sos field. I never had issues before but as it seems there is a conflict there with the new update ….the phone returned back to its normal times. I hope this will help others 😋
So, this is better battery life than what you used to get from your 13 Pro on previous versions?
Much better battery life, especially compared to 16.5, that version gave me like 6-7 max of SOT.
16.4 had mail app draining
…and so on.
Now is Almost the same battery i had on iOS 15.

The battery health to battery life ratio is nowhere near linear. It depends on a million factors, most importantly the iOS version. Update far enough, and degraded batteries are abhorrent because they can’t cope with the power requirements (which is why people swear by battery replacements), and replacing the battery helps far more than whatever percentage difference comes from the replacement. Of course, it will never match the original iOS version, even when the latter has a degraded battery.
Don’t update, and battery health is completely irrelevant. A 70% battery health iPhone on its original iOS version will have like-new battery life.
A 13 Pro with one major update? There’s probably no difference between 88% and 100%.
A few months old iPhone 14 Pro Max. The battery drain started after upgrading to 16.5.1. I forgot to put it on the charger last night, and the battery dropped from 25% to zero over 6 hours with no usage. Find My was doing something in the background but shows no usage.
I still have 99% battery health on my 14+ but it does feel like the battery drains quicker than before. I'm close to having it a year and wonder if it is warranted trading it in for the 15 pro so I can finally enjoy the dynamic island. Is it worth upgrading on a trade in so it doesn't cost as much?
Perhaps my biggest frustration with the battery life on my 14 Pro Max after upgrading to 16.5.1 is the unpredictability. Some days I think "this seems to have settled down now, it's not much different to what I had before" but other times it's horrible.
I'm a light user so I expect multi-day battery life so that I'm able to make an overnight or even a weekend trip without needing to pack a charger. I deliberately don't recharge every night so that I maintain a pretty good idea of how my battery (still reporting 100% health) is behaving. Previously I could always get at least 3 days between charges, usually 4 and sometimes even 5. With 16.5.1 my phone has mostly been dying (1% battery and then a forced power off) mid evening on the third day.
Because I don't charge every night I have automations set to put my phone into airplane and low power mode at 11:00pm every night and then switch off those modes at 8:00am each morning. A couple of nights ago my phone lost 25% of its battery over the 9 hours that it was in that airplane + low-power mode vs maybe losing 2 or 3% prior to 16.5.1. There was nothing in the battery section of settings to indicate any rogue apps using up lots of battery in the background (or the foreground).
This is really all very disappointing. I feel sorry for various Apple hardware teams, e.g. the A-series SoC developers, who do such a good job designing really power efficient hardware just to see their efforts compromised by the mess that iOS seems to be in terms of maintaining or, dare we dream, even making improvements to increase like-for-like-hardware battery life.

Standby time has been abhorrent on iOS since iOS 12 for iPhones and iPadOS 13 for iPads. I had never thought about it like that, and it makes a lot of sense: I really empathise with hardware teams. Their devices suffer because of the sheer inefficiency of recent iOS versions.
I have an iPhone Xʀ on iOS 12 and standby time is mediocre, far worse than my 7-year-old iPhone 6s on iOS 10 (both with original batteries, the 6s is far more degraded).
Like you discovered, efficient hardware doesn’t even help: the A12 Bionic is the best hardware to ever run iOS 12 and the A16 Bionic is the best hardware to ever run iOS 16, yet standby time is abhorrent on both devices. I hold no hope for an improvement at this time. Original iOS versions and standby is abhorrent.
I will even go one step further: I have an iPad Air 5 on iPadOS 15. The M1. The best chip to ever run iPadOS 15. Guess what? Standby time still sucks.
My iPhone 13 mini has, for months, getting worse and worse battery life, to the point where it was warm all the time, and pausing charging overnight due to heat. It was becoming slow to wake and sleep - click the side button to wake, and Siri activates as if I held it down for a second or two. Control center takes a second to open, when it should be instant.
The solution? Re-download the Fitness app, which I had deleted a long time ago.
I only found this out by hooking up the phone to a Mac with the Instruments developer tool, seeing that a daemon process was crashing and restarting every 10 seconds. Using 100% CPU for 5 seconds each time. The Console app showed this process was looking for the Fitness app.
This is crazy and there was no other way to know what was happening. The Battery settings are misleading at best, you would think that “Find My”, “Siri” or “Home & Lock screen“ was the problem.
Unfortunately my battery health is 90% after less than 12 months probably due to this bug.

iPhone 14 Pro Max here and battery draining has been quite noticeable since iOS 16.5.1 . I just got the phone a week ago and it's at 100% battery health, used to last me for good 2 days without any issues, even though I don't fully charge it. Now after the update, it barely lasts for one day and I have to charge it at least once during the day.
And standby draining has also been very noticeable. The battery would go down by 10% overnight, and it used to go down by only 2-5%. I did a check, and it doesn't seem like there are any background activities that could be the issue.
I hope this will be fixed with iOS 16.6 🙃

Terrible battery life on my iphone pro 12 for sure, geting worse and worse,
Phone doesnt seem capable to handle day to day operations, since ios 16 it overheats when playing music and using google maps, why did i buy the most expensive device of the lineup if it cant handle things my iphone 6 could do all day, and since last week it wont even charge fully because it’s overheating?
Wtf apple seriously?
Ipad pro 2021 on the same sinking boat.
Funnily, my ipad pro 12,9 1st gen, is completely unaffected by all this tomfoolery.
