iOS 17 | Battery Life & Health

[Reverend Benny]

iPhone 11 here with 17.1.1 very vanilla and only the MS 365 apps on + defender. Haven't charged mine for 3 days (i think) and its now down to 66%.
Its a testphone so its just sitting there really, not using it much at all, but still amazed what the stand-by time are on phones when they aren't being used.
The phone is hooked up to wi-fi and 4G

Edit: I don't have it connected to any Apple ID.

3 days and 34% of standby drain is 11%/day. If it includes the 100% percentage point it’s a little more, maybe 14%/day.

I think that’s decent for an updated iPhone with 4 major versions on and iOS 17, but it saddens me a little that iOS’ standby standard used to be infinitely better than that, and began to crumble back on iOS 11.

Battery health is 100%. What’s yours?

Getting into bed with 50% remaining 👌🏻

Aww fantastic result..My Iphone 13PM is one years old and battery 95 %

I just realized I could see when I charged it last (didn't notice it) it was on Monday 13:22, and today its thursday night 24:00. so roughly 3 1/2 days since I last charged.
Battery Maximum capacity is 86% on this phone.

Whats impressive is that I have MS Defender on it running in the background as well.

But just to be clear, this isn't what a normal user would see from a phone, its fairly clean, been sitting in the same space, same network connectivity, no iCloud and very few apps that are installed.
Its managed via MDM so that prob should have a negative effect as it reports back every so often.

Yeah, perhaps it’s a little lighter, but still, definitely not bad.

iOS’ standby time has been abhorrent since iOS 11, and whilst my iPhone Xʀ on iOS 12 would probably fare a little better, I doubt the difference would be massive.

Oh. I think iOS standby time has always been awesome and still is. I only lost 5% overnight on my 14pro over 8 hours. That seems pretty awesome to me! Im still on 16.7.2. Did it get worse on 17?

I have only tried 17.1.1 on the 2 company phones I have at the moment and they work brilliantly when it comes to battery consumption. Just upgraded my private iPhone 13 pro from 16.7.2 to 17.1.1 that's smeared with apps and connected to a lot more peripherals, will be interesting to see if its any different from the two others that has had smashing battery time so far.

7 plus hours and still 50% remaining. Wow!! That’s amazing battery life.

5% in 8 hours isn’t great. That’s 15%/day with absolutely no usage. For my iPhone Xʀ, that would mean a loss of over 2.25 hours a day of SOT just due to standby, or almost a third of the entire battery life in two days. Abhorrent. iOS 10 was a lot better than that.

Like I said, my Xʀ on iOS 12 doesn’t fare much better. It’s just poor and there’s nothing we can do.

 

[Reverend Benny]

Haven't been running it a full 24 hours yet but initial "feeling" is that iOS 17.1.1. is the same or slightly better battery time than 16.7.2 that I upgraded from. But, since I upgraded end of Friday and haven't been commuting with my regular workday user pattern, listening to music, browsing, IM and so on its hard to say if battery has improved or not.
I'm just impressed that Apple can cram in more features that uses the CPU and network together with more advanced apps and still keep roughly the same batterytime.

My 13pro has 85% maximum battery capacity.

Another thing I noticed is that if feels like its charging a little bit faster, or at least its what its visually gives a feeling of doing.

I wish… they definitely can’t do this, as much as I’d like them to. iOS devices always eventually crumble. Newer iPhones have better battery life, so they last a little longer. The iPhone 6s was already a lot worse by iOS 12, whereas the iPhone Xʀ, while perceivably affected by iOS 15, was way more usable. The iPhone 13, as far as I’ve read, has been affected by iOS 16, and it can’t match the iOS 15 numbers, even if iOS 17 remains stable when compared to iOS 16.

That said, sheer battery size on the 13 series may make that decrease not too important. The iPhone 13 Pro Max’s battery life is absolutely insane on iOS 15. They can’t break it this quickly, the 13 series will remain a battery powerhouse for a little longer.

Like I said once, let’s assume that moderate usage represents a 20% drop from very efficient usage. The 13 Pro Max is rated for 28 hours, so iOS 15 should give around 22 hours of screen-on time. Even if iOS 17 culls it by 15% (which is insane), it would still represent almost 19 hours of screen-on time. And honestly… would people notice that? I would, because I track it, but 99.9% of users wouldn’t. It’s too good to be impacted yet. And it has some chances of surviving. Let’s assume iOS 20 brings about a 40% drop. The 13 Pro Max would still be able to have an amazing 13 hours of SOT. Battery life would be abhorrent compared to iOS 15, but battery life is so good that even if you cut it in half it would still be usable if the user is somewhat efficient.

My 11 is dropping 5% an hour in standby

 

[prefuse07]

17.1.1 definitely has worse battery life than 17.1 did, and both are also definitely worse than 17.0.3 was.

Really hoping apple comes thru on 17.2.... really hoping.

Ugh, I should've just stayed on 16.5.

Nah, you really shouldn't, give yourself some cred that you are keeping your devices updated. If you have a read on what what security flaws that has been fixed from 16.5 to 17.1 you'll realize its lots and if you have another look at the the CVE score on those you quickly realize that its not an option to stick around using an old OS.

It's god that you are running at least 17.1, not only to protect your data but also the info you carry about others on your phone and the risk of your phones OS or apps being used as an attack vector.

That’s a joke. Apple could just patch older iOS version instead of just forcing you to update to newer ones .

And you can throw around all of the CVEs you like, yet the real-world implications are non-existent. Keep your devices with good battery life, folks, it isn’t worth it.

What part is a joke?

Sure, Apple could maintain older iOS versions and they do to some extent. Currently iOS 16 are getting the bugs and security issues fixed.
I do agree, they should really offer security patches to older devices that doesn't support the latest OS, and that goes for MacOS and all the others as well. Apple have a business model where they make money on older devices so there should be some incitement there.

But if you look at it from a developer perspective it would sometimes mean companies would have to support more versions (think 32bit/64bit as an example and added functionalities in OS).
Again, that could absolutely be done but comes with a cost.

Personally I would like to get a away from the releasing a new OS no matter what the platform is every year but we aren't moving in that direction. Even MS has given up on the whole 10+ year support cycle for one OS.

Sadly, it’s still forced, as you cannot install the latest iOS 16 version if your device is compatible with iOS 17. Which makes the whole “Apple supports older iOS versions” point completely moot.

My iPad Air 5 runs iPadOS 15.6. Can I install iPadOS 15.8? Of course not.

Is there any benefit to the 80% battery limit on the iPhone 15s?

Apple describes it quite good in this article

About Charge Limit and Optimized Battery Charging on iPhone - Apple Support

To improve the lifespan of your battery, your iPhone learns from your daily charging habits.

support.apple.com

The 80% limit isn't unique to Apples phones, it has been around on PC laptops for quite some with the purpose of extending the life of the battery. I do like that Apple has included it, its more obvious than the "Optimized Battery Charging" that iPhone 14 and below has which is essentially the same thing but not as "strict" as the 80& limit on the iPhone 15.

 

[Reverend Benny]

Have managed to squeeze 8 days of stand-by without charging my iPhone 11 that are being used as a testphone and still have 16% battery power left.
Sure, I haven't used it much and only have the MS office suite installed (with MS defender) but still, flippin impressive. Especially taking into account the battery capacity is down to 86%.

This is absolutely not to be seen as a real world average user reference phone but still fun to see how many days its possible to squeeze out using the latest iOS.

 

[Paul_W]

My battery gets even stranger. I've had pretty much the same usage today as I did yesterday. This time yesterday it was at 15%. Today it's at 77%

 

[kristof461]

As I said few post earlier. At home (I use wifi but LTE has full signal) it is perfect. If I use WiFi at work (I have one bar of 4G here) or 4G/LTE it could be a disaster. Of course mainly there was only one bar of LTE. I know it could drains significantly but I think my Mini was better in this case. Check this out
I barely used my phone yesterday and draining was visible. Sure it still lasted more than 12h and didn't use whole battery (80% optimization) but still it doesn't look good.

13Pro max this feature works very good when his born..after one years later disappear

Do you know what type of network and frequency you connect to at work? Bad coverage does drain battery fast, but it shouldn't drain it that bad. Test without using wifi at work for a day, just to see if it changes anything.
