iOS13

Note that the Battery info in Settings does not show the extra drain people are seeing in iOS 13. That shows only app usage, not system usage, which may account for the discrepancy (i.e. it's apparently background/system processes that are draining the battery faster in iOS 13).
Good point.

It's now 11:20AM. I took my iPhone XS off charge at 5:50. I'm now showing 95% charge. Seems about the same as iOS 12.

This isn't the first time there have been complaints about phones getting hot and fast discharges after a major number iOS update. It's happened to me in the past, too. Sometimes it can be fixed with a forced restart, and since that's easy to do, I would suggest trying that if you are having battery issues.

One time, around 2013, it happened to me, and I had to bite the bullet and restore as a new i-device (restoring from a backup didn't work), which stopped the discharge problem. I then re-added my apps back using some screen shots I had taken.

Given the number of apps now on my phone and the fact that one can't add them from iTunes anymore, that would be very painful.

I don't remember seeing this in any Apple documentation, but using iMazing to restore a backup of a different phone to an iPhone X running iOS 12.4.1 required updating to iOS 13.1.2 and popped up these little messages along the way:
Installing iOS 13.1.2 - Updating NAND Firmware...
Installing iOS 13.1.2 - Updating SE Firmware...
Installing iOS 13.1.2 - Updating Savage...
 


I’d consider rolling back to iOS 12.4.2 if 13 didn’t have iOS enhancements
You couldn’t roll back anyway. Apple stopped signing iOS 12 last week. The only devices that can do an iOS 12 installation now are devices whose iOS support stops at iOS 12 (e.g. iPhone 5s, iPhone 6, etc.)

Even just updating the iOS using iMazing will also bring up updating NAND Firmware, SE Firmware, and Savage. I used iMazing to update the iOS to an iPhone that I shipped to a friend.

Wow, iOS 13.1.2 just locked up on me so badly I had to force power down. Not cool. I wasn’t doing anything remotely stressful or unusual either. I can’t remember the last time something like that happened...

More iOS 13.1.2 dysfuction:
  • Formerly functional email intelligence - predicting the target mailbox when moving an automated fixed-pattern message from the Inbox - is screwed up, whether or not I enable Siri sliders in Mail preferences, creating obnoxious extra work.
  • I tried to create a Siri shortcut as a workaround, but that didn’t seem possible so I cancelled everything in the process, but that still left an empty, useless “shortcut” anyway that contains no actions, and I can’t figure out how to delete that.
 


I can’t complain about how iOS 13 functions, because I haven’t installed it on anything. However, despite my setting my preferences to not allow automatic updates, Apple still repeatedly shoves that blankety-blank installer onto every iOS 12 device. I delete it on a daily basis. I have enough room for it on the relevant devices, but I can’t feel complete confidence that it won’t somehow get installed despite the update preference I have set.

And Apple’s nagging about 2FA is now constant. My one brush with it back in April had me ready to rip my hair out, with constant prompts and sign-ins required on multiple devices. It was so intensely aggravating that I took advantage of the escape window to turn it off. This may be a relatively painless process for someone with one computer and one iOS device. But it seems to be chaos for an Apple packrat like me with a bunch of Apple devices. Does this ever get better? I expect to be forced to allow 2FA at some point, if and when I upgrade anything.

Another iOS 13 Mail problem: it occasionally plays the mail-sent sound but mostly is silent instead with no rhyme or reason. I didn’t have this problem with iOS 12.

On the plus side, Silence Unknown Callers at least seems to work, thankfully.
 


If this was referenced previously, I apologize, but as one who doesn't want to update to iOS 13.x for a while (just reading about the changes/problems is enough), is there any way to prevent the download of the installer? I have deleted it twice now but, as I understand it, it automatically downloads while the iPhone is idle and plugged in for recharge. I have auto updates turned off so that hasn't been the problem. But I have only a 32 GB iPhone 7 and would like to keep the space for more important things right now.

I’m seeing real problems (freezes etc.) with Apple News (especially when invoking Safari within it). This behavior is startlingly poor when iOS has been quite reliable prior to iOS 13.

Good morning, Kathryn. May I ask how you delete the downloaded iOS 13? My iPhone 7 has just announced it is ready to install – downloaded in spite of Auto Update being off...
I also have been harried to give my Apple password from time to time...

I mostly encounter issues on iPadOS running on a 9.7" iPad Pro. From time to time the iPad will freeze and not recognize gestures within apps. I have to kill the app and restart it in order for it to respond. Sometimes the freeze is so bad that even exiting via pressing the Touch ID/Home button does not respond for a while.

These symptoms are similar to what one would encounter when paging to virtual memory on a hard disk drive on a desktop computer. However, since there is no virtual memory, I suspect it is probably caused by iPadOS doing memory compression and/or clearing memory.

I thought that such issues only plagued Android. It looks like a lot of memory management optimization and task scheduling for interactive usage needs to be done by Apple, especially for the older devices with limited (2GB) RAM.
 


Using Airport Utility, I attempted to log into an AirPort Extreme 'ac' and a 1st-gen Airport Express 'n' with both my iPhone XS and my iPad Air 2 (both on latest iOS 13). After typing the password, Airport Utility crashes every time. I logged in with my wife's iPhone 6s still on iOS 12 without a problem. I've sent a bug report to Apple.

Overall, I've been satisfied with iOS 13 on my iPhone 6s, and it feels generally as fast as iOS 12, but I have noticed occasional pauses (especially in Mail) or failures of the interface to respond to input that are new to iOS 13.

For Mail, it sometimes takes a few seconds to populate the messages on screen. For the interface, the phone will appear to freeze for a few moments without any feedback, which has made me wonder if the touch screen is starting to fail, but I agree some iOS 13 resource contention issue is more likely.

5th gen iPad has been freezing regularly when I use the two-finger spread to enlarge images, particularly Pinterest (which may be because that's when I tend to do it the most). Have to quit and restart the app. Haven't had an entire across-the-board system freeze.
 


I'm using IOS 13 on an iPhone 7. I haven't noticed any (new) battery problems. The phone is old, and the battery was already showing its age. I haven't noticed any additional battery drain from IOS 13.

Another problem which has continued from IOS 12 is that Mail sometimes opens with a few messages from months ago, and then takes a long time to load all the rest.

Then there are those interface changes…

Maybe they actually listened (but it's a bit hard to tell...):

Not sure if this is the "freeze" others are reporting, but on my iPad 6th. gen. with iOS 13.1.2 Safari frequently stops displaying pages. At this point I'm able to enter new URLs but get blank pages every time. I have to quit and restart the app, or reboot (latter works more reliably to restore normal behavior). This has happened several times a day since 13.1.2. I had the same problem once so far with the Gmail app.
 


Occasionally, I can be easy to please. "Silence Unknown Callers" has been worth the update since the first public beta.
I was so excited to see Apple introduce this feature that I used on my Palm Treo, what, 10 years ago? I enabled it and started missing really important business calls from people who didn't leave voicemail, so reluctantly I had to turn it off. When did valid callers stop leaving voicemail?

Welcome to the club. I put iOS 13 beta on my iPhone 6s in mid September, and it has not been the same with many crashes, app lockups, etc. Removed the beta when iOS released and upgraded to iOS 13.1.2 with no improvement!

I updated an iPhone SE (purchased in 2019 and with 100% battery capacity) to iOS 13.1.2 from iOS 12.4.1 and wish I hadn't. I'm currently experiencing several weird problems, including a high rate of battery drain, although the update was days ago, and the system has had plenty of time to settle in and do any housekeeping it needs to do. I'm currently trying to isolate/identify all the issues (and I'll post updates if I can nail anything down).

I'm currently trying to isolate/identify all the issues (and I'll post updates if I can nail anything down).
I reverted to an iPhone 5s with iOS 12.4.1 for a while but had to use an external power supply, due to the low power state of the internal battery. Tried iOS beta 13.2 on the iPhone 6s, but no joy, so restored from Finder to iOS 13.1.2 and backup.

I'm now using an external power source on the iPhone 6s to keep it stable since last night with no dramatic power losses. So far OK, but am not optimistic. This morning, power dropped to 95% with the external power source. Updated all apps and now back to 100% with external power source. I do not think these two items are related but just power management problems by the phone.

Previously, after installing beta 13.2 and reverting to 12.4.1 on the iPhone 6s offered no improvements, I found it troubling. Have a case with Apple through executive offices so will see what happens.

One caveat on Silence Unknown Callers (SUC) is that it will display in Recents list. An easy mistake is to see on your home screen a notification of a call, and if accidentally touched, it dials that number!

What is Apple thinking? (I just turned off notifications, which means I won't know about any calls coming in. Why not have Silence Unknown Callers not show up in a banner,but known callers only?
 


Well, I made the mistake of updating my iPhone SE to iOS 13, since it wouldn't accept the iOS 12.4.2 update.

It wasn't very long before I saw my battery usage dramatically drop. A typical day pre-IOS 13 was to charge the battery at night, when it had about 70% remaining. However, since iOS 13, within 9 hours or less (of minimal usage), my battery has dropped to 40%. And it just keeps dropping.

I looked under Settings > Battery > Battery Health, to see what app(s) were draining my battery.

First item to show up: Flashlight... a whopping 96% activity and it's been active since I woke up this morning! Everything else (iPhone, iMessages, etc.) were around 1-2%. But 96%? For an app I didn't even install?

It turns out it's there, all right, always On, in the control center (which I don't really use). So I removed it, thinking that would turn it off. Turns out, No. Even though it's been removed from the Control Center, it's still using up my battery.

I've searched the Internet and no one really seems to care about actually physically turning the flashlight off permanently. Why isn't there a setting for this pre-installed app? It's driving me nuts. In the meantime, I'm just watching that battery drain and drain and drain.

Yes, thanks for pointing that out! I already realized the problem, from using a similar Do Not Disturb trick, and have developed manual procedures to help mitigate it, but I forgot to mention that issue, which is an important one.

I generally Block Caller for unknown calls, due to the heavy phone spam/scam abuse I get, but Apple's user interface gets extremely tricky, with microscopic affordances, when there are any at all, and it's hard not to hit the wrong thing accidentally (a major problem, in general, with Apple's current UI design).

Um... if the Flashlight is on, you should see a bright white light coming out of your iPhone... (which, naturally, would drain the battery rapidly).

Is your light off, or hidden? Something doesn't seem right here (in addition to the unsurprising issue of not being able to delete the Flashlight program).
 


We updated a few iPads and iPhones to iOS 13.1.3 successfully today, though the updates took longer to complete than expected. They seemed to get stuck with the progress bar around 1/8th of the way through for several minutes, but after a few moments of growing administrator panic, they proceeded normally. So far, we haven't noticed any post-installation problems with iOS 13.1.3, but the day is still young.

Whoever is responsible at Apple for dismal software Q/A and releasing half-baked software with significant bugs should be fired...
And it's not like he'd need to get a new job, given that he had already received more than $700,000,000 in personal compensation from Apple by last year....

(Invested at a conservative 4%, that should provide Tim and his heirs with $28,000,000 per year forever without anyone lifting a finger to work....)

I'm currently experiencing several weird problems, including a high rate of battery drain, although the update was days ago, and the system has had plenty of time to settle in and do any housekeeping it needs to do.
And iOS 13.1.3 (for iPhone and iPadOS) is now available. I'm sure this will fix everything.
I updated the iPhone SE to iOS 13.1.3 hours ago, charged it up all the way, turned off all apps and everything else I could find to disable, and it's draining the good battery at a ridiculous rate. What in the world is going on here? This had been a rock-solid phone in iOS 12, and I didn't change anything during or after the update to iOS 13, other than to again disable some unwanted Apple preferences that had been silently set by Apple and update apps that needed updates for iOS 13 compatibility.

iOS 13 is one of the worst Apple releases I've experienced in a long time (but, of course, I skipped macOS 10.13 and subsequent versions for my production Mac). And I'd never have installed it, except Apple keeps forcing updates in order to get security fixes. [expletives deleted]

Well, I admit I am not the best example of an iPhone user. I tend to update to the previous update the month before Apple releases the next incarnation, because, by then, I figure they've had a year to work all the bugs out.

This year, however, because of all the security fixes, I upgraded to iOS 13.1.1, waited for Apple to do its thing (about an hour), and noticed the battery health issue almost immediately.

Someone had mentioned to check Settings > Battery > Battery Health, to see which apps where draining the battery. And that's where I discovered an app called Flashlight was draining my battery at an alarming rate (70-80%) every day. I discovered that it was located in the Control Center and that I could turn it off there (along with Bluetooth). I then went to the Control Center and removed it from the Included Controls.

But when I saw the battery still draining with little use (minimal iPhone, iMessage, etc.) and that the Flashlight was still the culprit, I couldn't figure out how to stop this app. Unlike Cellular, Bluetooth, WiFi, et al, there isn't a separate setting for a Flashlight app anywhere in Settings.

So that was when I reached out to this site for help. Apparently this app doesn't really "exist" in terms of controlling it beyond including it in the Control Center. So I re-installed [iOS 13] then restarted my iPhone (doing a hard restart), and everything seems to be back to normal.

It's probably a bug, but I doubt it's high on Apple's priority list when there are more emojis out there to include in the next release.

Re iOS 13.1.3: On the positive side, my iPhone 6s will play music without crashing and works at least down to 92% power. One can access non-power-intensive apps without crashing, and no apps have hung for the last 5 hours or so with the occasional playing of a song. Battery drain with normal usage appears(?) normal at this point. So, if they can fix battery drain and crashing problem when using two more power-intensive apps, like Music and Maps, at the same time, that would be nice.
 


I enabled it and started missing really important business calls from people who didn't leave voicemail, so reluctantly I had to turn it off. When did valid callers stop leaving voicemail?
This is apparently a pretty common practice now, I’ve seen this mentioned elsewhere. I think the caller either expects you to just call back or might call you back later. Too much time to spend leaving a message. I’ve had people send me a text telling me they had called (but didn’t leave a VM!).
