It's been running the same version since 13.1.2 got released. I don't think it has settled in yet, unless it takes a week. Also, my battery health is 75%, but lasts the entire day with 12.4.1.
My 6s plus is at 78%.
You definitely should replace the battery if you continue to use it as your main phone.

Not only do you have to deal with battery drain but it causes performance issues as well.

It's still a bit odd that the phone only started acting up with iOS13.
 
I know this can be a PITA, but has anyone tried resetting and setting up as new? The only reason I ask this is because my old 6S Plus and 7 Plus did not have any battery issues like the ones I’ve read about here, and both were updated from 12.4 to 13/13.1/13.1.1/13.1.2, or whatever the iOS 13 path has been.

And the batteries on both were around 85%.
 
Is it just me, or does it seem like every iOS release within the past quarter decade or more has had a battery drain issue?

Sorry about that, it's actually 13.1.2, I kept updating when a new 13.x update got released hoping that it would fix it. It's been weeks now, and my 6S still can not last a day without being charged at least 5 times a day. It drops heavily during use, or even powered off. Overnight, it would be 100% to 50% in the morning.
6s here. I think you’re just seeing a coincidental timing of your battery finally giving out. I’m on my 3rd battery (I replace them with $25 ones) and I noticed my battery life falling off a cliff PRIOR to iOS 13. If anything it’s gotten slightly better with the new OS.

Once I pop in a new battery I’ll be a happy camper, but this phone is likely going to head to my dad if I finally get around to upgrading in a few months.
 
Can you still get a new battery for $29 at the apple store? That may help a 4 year old phone.
 
I'd like for you to show me how to revert my device back to iOS 9-10 and then I'll gladly prove it. I think enough claims have been made here that it's happening to warrant a discussion. If you think it's not happening, show me with your older device. It's not that complicated.
The proof in question is in relation to a malicious conspiracy.
 
Running latest beta 13.1.2 and awoke again this morning to very poor battery life. Taking the advice I found here in the thread I reset settings and have already noticed a major difference for the better. The first hour or so this morning I was down 30%, barely using the phone and for the past several hours I’ve only dropped 20% additional and I’ve been using the phone. Very pleased with the results and I would recommend a settings reset to anyone suffering from poor battery life with iOS 13.
 
My XS Max and iPad air 3 seems almost the same or a little worse but not that much. On the other hand my iPad air 2 suffer from drastic battery drain since updating to 13.1.2 from 12.4. The battery health is at 87% and it was decent on 12 but really awful on 13 so far.

I think iOS 13 is realy not optimized for older devices.
 
The burden of proof isn’t in negating something that was claimed.

That said, since one example that doesn’t fit is enough to negate it: iOS 12.

Unfortunately once the battery drops below 90% things start to become more and more noticeable as far as battery usage goes, especially at it gets closer to 80% (which is basically where the battery is not considered to be all that useful anymore).

In your case, trying something like resetting settings or even reinstalling might be worth a try.
Nope, iOS 12 really decreased my battery life from iOS 9 on my iPad Pro 9.7 after Apple forced me to update.

Not sure what’s worse, flat earth types or the “PLANNED OBSOLESCENCE!!!111” trolls.

I’ve noticed a bit of a dip as well on my XS Max and iPad Pro, I’m assuming it’s a bug that will be fixed with an update.
“I’ve noticed a bit of a decrease, but nah, updates don’t decrease battery life”. Brilliant.

I agree with that to some extent. I don’t believe Apple really optimises the latest IOS for 3 or 4 year old devices, which is why a lot of people with older devices report worse battery usage after upgrading to the a new IOS. It’s too much of a coincidence for so many older devices batteries suddenly ‘failing’ right after updating, that there must be something else going on. I don’t believe this is intentional by Apple, just that they probably don’t spend as much time optimising the latest IOS for older devices Instead and prioritise optimising it for the latest ones.

Good news is soon you should be able to downgrade to anything between iOS 10-12 forever once there’s a release based on the checkm8 exploit I believe. It’s been hard following all the info that’s been coming out about it. I have a 6S that needs a new battery, I’m going to have it replaced and keep that phone for as long as possible.

Whaaaat? Can u give me the link or more info,please? My dream is I downgrade to iOS10 😁
 
I have a brand new battery on my iPhone 7+ and battery life is subpar. My iPhone 6 is actually better for battery life than the 7+ (because it's on 12.4.2).
 
Anyone got an iPhone with iOS 13 and a Mac with Catalina? I heard from other threads and posts that the battery drain is from conflicting files during iCloud backup from a Mac on the same account with anything older than Catalina? (I got a Mac Pro still on Mojave) Does anyone have a Mac with Mojave or older with an iOS 13 iPhone or a Mac with Catalina with an iOS 13 iPhone, has your battery been better after your Mac upgraded to 10.15? I just hope this is true, so we can all solve this battery issue.

Only if your device has an *ipsw file that will load. The iPhone 6s has no such file. Apple says:

Available for: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch 6th generation

Sure doesn't make sense why a trillion dollar company doesn't invest some money in taking care of the millions of customers for older devices...unless they wanted you to buy the latest products out there. Which they do. Seems rather unbelievable that with all their resources, they can't slap a couple of software engineers on to fix this persistent and worsening issue.

Unless, oh wait, they wouldn't want to.
 
6s iPhone.
still love this phone.

but you are correct. i have also started a thread on this issue elsewhere.
iOS 13.1 really killed ability to use the phone in the way that i had been.
was able to get 7 to 8 hours before, but now about 4 to 5 hours.
i can not use the phone in the same ways i was before.
but i have tried literally everything;
no background app refresh; almost all location following turned off. no heavy viewing of videos. etc etc.
still something is eating it.
i have also experiemented with enabling low power mode more or less constantly.
still something is eating battery with this update.

but i also have a macbook air as well. and macOS 10.14.6 battery duration has also taken a stark decrease.

i believe the two issues are caused by the recent updates. i think that they are related.
i think that iOS 13 and macOS Catalina preparation in Mojave's final updates has changed how the mac and the phone are seeking either network or iCloud services.
on the iPhone, carrier signals that were strong before are no longer strong.they are very weak now.

i am hoping that once Catalina comes out, things settle down between these two devices.

again, you and i both share the fact: iPhone 6s ran well using iOS 12 all versions.

we pray that the 2020 spring iPhone rumored to be an iPhone 8 replacement is worthy.
My XS Max is definitely getting about 3 hours less than I used to

that's nonsense, the guy himself said that downgrading will be impossible because of the secure enclave and system apps dependent on it

Your battery is knackered. Time to get a new one.

Nice straw man argument with the flat earthers. Sure is coincidental all of these "trolls" came out all claiming the same thing, isn't it?

If you're so confident these are in fact trolls and not legitimate people with legitimate claims, just post some evidence that disproves them?

Take an older device, put it on iOS 13, and show the battery life performance? Find an older device running an earlier iOS version and compare the two? It would be quite a simple experiment to run.

We'll be eagerly awaiting your results.

It‘s very difficult to prove a negative, really the onus is on you.

I’ve also experienced an important reduction in battery life in iOS 13.
In the early betas it was fine I think, but starting from the latest iOS 13 betas the battery life was shortened. Then I left the beta when the final version was released, and now in 13.1.2 the phone still smokes the battery.
I have an iPhone X at 90% battery health.
before, I could make the day and at night still have maybe 15-20%
Now, for the same usage, I need to charge it in the afternoon/evening, the battery drops much faster.

I just disabled the location services, as I saw the icon pretty much all the time, let’s see how it goes.
