iOS 17.3 ― Bug Fixes, Changes, and Improvements

[Populus]

Yes, I’ve installed this update a couple of days ago, when it came out . Unfortunately I can’t delete the marvel app, but it seems to consume battery only when I’m actually using it. However, I might try to reset the network settings and see if this is fixed. Otherwise what would you suggest? To create a backup with iTunes and reinstall iOS, then restore the backup?

iTunes? What’s that? Joking

Honestly, I’ve never liked to drag a backup from an old version when I perform a clean install. Fortunately, the only data I care about are photos and videos, and those I already save them to my Mac and external drives. Everything else is either expendable, or saves the data via iCloud.

But that’s just me, you can perform a clean install using your Mac, then restore the back up, and see if that works for you. But definitely, if there’s something, an app or a song causing the drain, it’s likely you will bring it back with your old backup. That’s just the way I see it. Other forum members will disagree, so you do you.

Nope, doesn’t look good to me either, especially being a max sized iPhone (big battery) with an A15 SoC, which is very efficient. Probably it is because it is indexing if you recently updated it?

Here’s my advice: If you can, first delete the Marvel Champions app if you think it can be the culprit, and leave it rest a bit under WiFi connection and charging. Just in case you can also reset the network settings. And leave it for some hours or even a whole night to let it do it’s things.

If none of this works, you know the deal: clean install.

I think I’m gonna refrain from updating my A15/M2 devices, for now, so thank you for sharing. iOS 17.4 looks promising in terms of performance and it is just at beta 1. Hopefully the final release will be even better!

It's not indexing. It's just iOS 17 and clean install doesn't help at all. I already tried that. I don't whine a lot but this is the first time I'm really annoyed with apple and the battery life I'm having after updating to the new iOS version so I'm not staying quiet.
If you don't care about security updates then stay on iOS 16 with your A15 iPhone. I wish I could downgrade from iOS 17.

Also not sure why but out of a sudden safari keeps lagging and freezing. For example I'm opening safari, tap to open a new tab and nothing's happening so I'm tapping again and again and again... and after waiting few seconds it finally opens multiple tabs. Force restart helps for few hours.
There are also stutters when swiping to incognito mode and opening a new tab.

I get your point, but you see, I’m not using a Mac, but instead im relying on iTunes for windows to create backups .
I’m also struggling to do clean install every time because of the photos and videos, including albums .I still haven’t found the best solution to preserve albums between software reinstalls.
Could someone step in and help? Many thanks

There can be a number of things creating this issue, and you seem to have at least a few good idea on where to start to adress these issue.

First off, its hard to draw any conclusions as you haven't fully charged your battery on the screenshot.
Another thing can be to simply clean the internet cache, you may have things running in the background there.
I see that you are using dual sim, so that can also affect performance.
Network settings is a good start, also have a look at your router settings.
Do you stay in places without wifi coverage and bad cellular coverage on any of the operators? That can cause drain and non of that is visable in the battery statistics.
I'm guessing there is a few background services running as it is draining the battery during the night when you aren't using the phone. Check location services too, anything there?
Try and clean off apps that you don't use and check so that you have a bit of storage space left so it isn't maxed out.
If its a company phone there might be services running in the background.
Update the apps on your phone (force update) and if you are using VPN, turn that off.

Above is just a few things you can look at, but its a start

I've been running iOS 17 from 17.1 on a number of devices without any issues and its just keeps getting better.
Would say that iOS 17 is better than 16 in terms of battery in my case, but as always, alot is about how its being used, apps, peripherals, device and a number of other things.

Sync things to the cloud? But I guess its depending on what albums and services being used.

And not only the iPhone has software bugs, the watch sometimes gets stuck, freezes and does not receive notifications. The solution for now is to reboot. It should be noted that I have an iPhone 15PM and the latest Series 9 watch. Both of them run the supposedly stable versions of iOS 17.3 - 10.3. I think Tim Cook need to start thinking replace All programmers and software writers

Have to say, I agree.

On cleanly installed Apple Watch Ultra 2 and 15 Pro Max, I have to restart both at least once every couple of days because of niggles or things just failing to work. It can vary from apps crashing to messages not coming through, to silent notifications, to slowdowns. Awful software in my experience, and even worse on the HomePods.

Thanks for your reply, my usage patterns haven’t changed at all. I can’t upload to iCloud due to space limitations .
I don’t think that a full charge affects the standby drain . I’ll try to find a battery curve from an earlier update, you would see that the standby drain simply isn’t there. Plus that’s my private phone and I have been always using dual sim.
Btw what’s the internet cache cleanup? There is also storage available.

The truth is that I switched for the first time after 14 years to Apple and iOS after recommendations, battery time and more. For now I'm just disappointed. If there is no serious software update during the next month, I will go back to Android, which in my opinion is more stable at the moment, which I find surprising.

It used to be like this before iOS 15. I jumped back from Android to iOS after I sold iPhone 12 and still I am facing similar issues. It is already better than iOS15/16 but still I am experiencing animation stutter and system slowdowns. I bought iPhone 15 Pro Max week ago and now I am thinkinh about returning it.

𝘏𝘮𝘮𝘮…shall I care more about getting an hour more on my battery daily

𝘰𝘳

Risk having all my sensitive data stolen because I didn’t update my phone so I could hypothetically get an hour more battery life?

This is one area where I will come right out and condemn anyone who gives this type of advice. It’s bad advice and don’t listen to it.

 

[P_Watt]

Since updating, Maps in wireless CarPlay is no longer giving voice directions, although navigation is working.

Maybe too simple but is volume up (separately from any audio output)
and did you select the full navigation audio? see below

That argument again. It just shouldn’t be there in the first place. Have you seen anyone with older iPhones running on iOS 15 or iOS 16 being hacked? I haven’t seen or read any cases , except for VIPs such as government officials.
So the story would go like this: “let’s add some more features” —> new security holes due to poor programming
“Let’s patch these holes”—> Either rewrite the code or add security layers.

But does contributes to less SOT?
Partially it could, as more layers cause more cpu and resources usage.
But is this the case???
Well, I hold a PhD in Computer Science and have expertise in embedded programming. So…
It has nothing to do with security. It just could be a rogue process running in the background. Or some polling routine of another process that waits for reply from a crashed process.
The dilemma of security vs battery life is just BS. Think of the average consumer:
“Well, I lost 1-2 hours of SOT but I definitely feel more secure “ 😂 lol, no.
And on top of that, the very limited output of information with regard to power consumption in the settings does not help clear things up.

Sorry, I means Safari cache.
Regarding iCloud, just purchase more space, its peanuts compared to what you paid for your phone and a simple way of being backed up when your phone gets lost.

I don't think that's much different from your current except something is draining during the night.

Exactly, but there’s no info for what that could be . It also drains during the day, but since I’m using the phone it’s barely distinguishable .

I had a bug during iOS 15 or 16 for quite some time that made me hate my iPhone 13 Pro, wasn't there initially when I got it but all of a sudden my battery was draining like mad.
Had it going on for half a year or so until someone here came across a bug where the a service/process is trying to use fitness/health app, and if it has been deleted, it will keep on trying and crash in the background. When I reinstalled the app (i don't use it) it solved all my battery issues.

Not saying this is what will solve yours but more point towards that it doesn't have to be iOS 17.3 related or if it is, it could be a number of things that is causing it.

My experience with 17.3 is that its prob the best release so far, but that doesn't mean others (like yourself) have the same experience.

"This type of advice" geez... That's literally why I added at the beginning of the sentence "If you don't care"??
I'm not responsible for what they're doing with theirs phone and i didn't say anything like "yes! don't update! iOS 17 is trash. Who cares about security updates?!?"

Also - for you that might be just one hour, for me unfortunately it's more than that, a lot more.

I hope you find what's draining the battery. At the end of the day its a lot of components that all interact and if one fail that can cause the drain. I wrote in another thread that there would be nice with an "advanced" option in the battery section to be able to find more in detail what is causing the problem and I have suggested this feature to Apple.
Not saying it will solve all problems but lets say you have a BT device that isn't behaving as it should and constantly polling the device, then you would be able to troubleshoot it easier.

I haven't had any battery issues or heard any of my users complain about it (manage around 1500 iOS/iPadOS devices) but that doesn't mean there aren't issues, I don't talk to my all my users but we haven't had any cases logged regarding this in a long time. Network connectivity has been an issue from time to time on both Mac and I-units, but that is sometimes down to a complex environment and random bugs on the devices.

For me it isn't a choice between battery time OR security updates, its obvious that you can have both.

For me 17.3 is a train-wreck

Stuttering UI (especially after unlocking) and sometimes phone gets hot and drains battery.

Apple again is deliberately slowing down old iPhones. What a shame.

What phone? Been using it on SE2, SE3, XS, 11, 13, 13pro, 14 with none of the issues you are mentioning.
Could be app related, peripherals related, network issues or something else?

I would contact Apple support and see if you can provide them with additional data to see if they can nail down what's causing the problem.

After some digging I discovered that 17.3 had muted spoken directions in the iPhone Maps app. Working again.
