Battery issues since update?

My iPhone 6S is only 13 months old so I can rule the battery out. Plus mine was instantaneous with the update. At least I know it’s software related.
So when it's fitting and there's no way to really deny it then it's just the battery and it all makes good sense, but without that it's the malicious conspiracy of updates. Convenient.
Makes one wonder why the Apple employee first said it wasn't the battery. Looks like the employee was just hoping he would go away and let the AC+ expire. It sucks he had to beg a senior employee for a battery replacement.
Because 1 year old iPhones don't have battery wear. Also because in the second update of most iPhonmes, battery life is bad so by the end of the second update the phone's battery is wrecked
My 6S is around 22 months old and I too noticed unusual drain post iOs 11. I am down to 18~22% by the end of the day, whereas earlier it would be at 48~55%. Same usage pattern.
If you have a battery drain problem on 6s after upgrading to iOS 11, I don't think it's because something is wrong with your battery. Apple recently replaced the battery on my 6s, and with a new battery I see exactly the same problem as with the original one: on iOS 10 the battery gives 2-3 hours of usage more than on iOS 11.
I went back and forth between iOS 10 and 11 several times with clean installs without touching backups. I tried re-calibrating the battery. Nothing helps, not even replacing the battery on your 6s with a new one. The problem is with iOS 11, not your batteries or devices.
Yeah I know. My battery life was fine on iOS 10 and suddenly went bad the moment I installed iOS 11. I’m aware it’s software related and nothing to do with hardware.
I have a first generation iPhone released in 2007 and the battery can still hold a full days charge. Granted the phone is 2g and has basically lived in a box for several years but it still doesn’t explain why (if as you say 2 years to worn out) the battery in that old phone still performs like a champ. I can also look on eBay and see many other original and 3gs Iphone’s With fully functioning batteries, no doubt degraded but functional nonetheless.
I can only assume Apple are using inferior batteries or are actively using their updates to take a seemingly fully functioning battery one day to appear significantly degraded post update.
I wouldn’t say I’m a conspiracist, regardless of how my assumptions sound but I only can go with real world experience & usage of iPhones, iPad over the past 10 years and imo when an iPhone or earlier iPad 2 are functioning so well after so many years, then it makes sense that Apple would not be comfortable with this.
They basically built them ‘too good’ which is not good for future sales. So changing tactic by way of using inferior battery tech, designed to degrade sooner or some cleverly coded software updates that can target specific models deemed (by Apple) past their sell by date. I don’t know, all I know is from personal experience, Apple devices used to be built to last, nowadays longevity Is not a priority.
I did the same with my 6s last year, when I updated to iOS 10. Went back and forth between iOS 9 and iOS 10 testing the battery life. iOS 9 lasted 40 mins longer during continuous use. Same usage patterns. Both set up as new.
On top of that, my phone’s battery mAh capacity dropped the day I updated to iOS 10! Happened literally overnight. That’s one of the main reasons I went back to iOS 9. It didn’t show a higher mAh count even when I went back to 9, so the damage was permanent.
I experienced the same with my 7 Plus when I updated to iOS 11. Prior updating, battery was averaging around 2840 mAh. After updating, it’s around 2700 mAh! My battery health went from 98% to 93%. And it’s legit because I’m using coconut battery on the Mac to accurately tell the mAh level. Not some app on the phone that “guesses” the battery health.
I am starting to think that's the case as well. After all they don't have an incentive to make the phone battery efficient in a new update when they could get a 100 bucks for a new battery.
Here is a good example of the difference in battery 10.3.3 and 11.1.1 on an IPP 12.9 G2
IPP #1 on 10.3.3
Battery 62%
Usage 7:49
Standby 88:09
IPP #2 on 11.1.2
Battery 67%
Usage 6:01
Standby 15:33
Both are being used to read email and general Safari browsing with some basic iMessage and Kindle.
Nothing battery intensive.
Use is not exact between these but overall is close.
Something changed in 11.x regarding battery use and efficiency.
The ability to charge every few days has gone away.

That’s not necessarily true. Family members and I have used iPhones that are 3 or even 4 years old and still make it through the day at least. In fact, I’ve never had the battery degrade to the point that I’ve needed to replace my t after just 2 years. Theoretically, the battery should degrade to about 80% of its original capacity after 500 full charge cycles. When a phone is new, it may take me a day and a half to two full days to do a full cycle, so getting 3-4 years out of a battery shouldn’t be unreasonable.
I doubt that coconut battery is very accurate. I used it several times before my battery was replaced, and the results jumped up and down between 82% and 86%. Even the tests they do at Apple stores (Genius bars) don't seem to be very precise. First time I went there with my 6s, their test showed 84%, but on a second visit, it was 89%. They still replaced my battery after the second visit saying that some 6s had defective batteries. It did not do much difference for my 6s in terms of its battery life on iOS 11 relatively to iOS 10.
Then your battery was faulty. It should stick around the same battery health percentage. Changing from 82 to 86 is not normal. My phone is around 93% after updating to iOS 11. I check it almost daily. Doesn’t change. Occasionally it would go to 94 or 92, but mostly 93.
It’s important to understand that no software measurement system can check battery health with 100% accuracy simply due to the battery technology itself where chemical reactions cause it to charge and discharge.
Having said that, coconut battery should only be used when your battery is charged at 100% as per your phone battery meter.
Yep I only check it when it’s been at 100% for at least 30 mins (I charge it using my Mac often).
The issue is these iOS updates are so unoptimised at the beginning and Apple takes months to fix it so the battery is charged twice a day for quite a few months before it's fixed by which time the battery health has taken a nose dive. My 6 battery needed replacement after 2 years because of frequent charging on iOS 9. My iPhone 7 was lasting well into the second day on iOS 10. Now I charge it twice a day. That's what results in battery replacements after 2 years.
*shrug*
Not saying that battery life doesn’t decline, but I’ve never had to charge an iOS device twice a day, even one that was over 3 years old and always running the latest OS. I guess I’ve just been fortunate.
and in the meantime the battery will deteriorate and will be ruined irreparably !!
I don’t take coconut battery results too seriously either. My battery health always jump between 73% and 86% when both times Appel tested my battery it was at 87%.
And I also saw a difference in battery life the day I updated to iOS 11. I lost several hours of battery life and the phone goes hot very easily with basic task. When I updated to iOS 10 last year I didn’t see a difference with the battery life.
