All Devices iOS 13.3.1 ― Bug Fixes, Changes, and Improvements

[jrdatrackstar1223]

Hey, is someone with an iPhone 7 or 8 getting 6h or even 7h of Screen-On time with iOS 13.3.1? Maybe something close to this?

I have a 64GB Verizon iPhone 8 and I’m pretty sure I’m getting those hours:

Thank you pal, I see an average of 4 and a half hours of screen-on time, but I suppose that you don’t use 100% of your battery, as your activity shows less than 50% of usage. With iOS 13 is harder to tell how many hours of screen time you’re getting from your last charge (iOS 10 battery graphic was better).

I ask this because I only see negative comments about battery life on the forums, and I wanted to know if those who don’t complain and don’t post here are having good battery life.

I’m not gonna lie, with iOS 12 I am getting 7 hours of screen and use time on average. Last time I checked it, counting each blue bar individually from the charge, I got 6,6h. That’s with an 87% of battery health, because when this phone was new it lasted 10 hours of Screen On time, and it was awesome.

Many on-line tests aren’t showing those huge differences that I read here, going from 7 hours on iOS 12 to 3 hours on iOS 13. I’m not saying I’m not believing them, but maybe they are a minority, and most people is having the same battery-life.

And yes, I’m concerned about this because I want to update my iPhone 8, with a battery health of 87%, from iOS 12.0.1 to iOS 13.3.1 just for security reasons, as well as all the features of iOS13.

Yea, I was going by my average. So at the rate I typically go (I never fall below like 60% in a day), I would get 8-9 hours.

RAM management is still an issue on 13.3.1. Might be slightly better than 13.3, but it still needs to be improved. Apps particularly like to refresh over night when phone is sitting idle.

Are you that type of guy who keeps like 100 apps open and expects that the first app that was opened to not be refreshed?

Well I have only 3 tabs opened in Safari on my iPad Air 3. No other app in background. Every 10 minutes the tabs are reloading. So is this normal too?

 

[Flopstar]

No, at most I have like 10 apps open. Oftentimes my phone reloads 3-4 of them at once with only 7-8 open overall.

I’ve lost 12% in standby on my iPad Pro since the update went live to the public. It’s been sitting on my desk doing nothing.

I've been reading the posts about "better battery life" on 13.3.1, I wonder what the heck am I missing??
Yeah, my iPad Pro battery drain is worse than ever now - ...sure its a 2015 model but it was never this bad. I'll just have this sitting on my desk with a weather radar app open, I might lose 18-25% in 45 min. Very random drain.

As for my XS Max...same thing. Battery drain is much faster! I'll take it out with 100%, keep it in my pocket turned off. After 30 min. I'll check it and notice the battery is down to 95% If I take a few pics...it may drop down to 88-92. within 1 hour. Might not sound horrible, but its a big difference than before.

I have had to do a few hard resets on both devices when battery would CONSTANTLY read 97%, once rebooted, the % is less (93, 95). Lot of random odd numbers.. ugh.

 

[corruptdream]

hi, i have an iphone 8 with 12.4. in comparison, 13.3.1 is stable ? i prefer an full functionally device over security updates. thanks

I left my phone unplugged overnight, iPhone XS on 13.3.1, battery went from 100% to 99%.
there is definitely something wrong, for me reinstalling iOS and restoring the backup works most times to fix issues. Good luck.

My iPad Pro 11 inch on 13.3.1 looks to be having a similar issue. Checking Battery Stats overnight, I’m seeing Music running as a background activity for maybe an hour, and that’s it. But my Battery drained from about 75% down to 38% just sitting there on my table with the Smart Keyboard case closed on it, display off. I used to be able to go at least 2 days of normal use, maybe plugging in here and there for a quick charge. Battery seems way worse now in 13.3.1

As for my iPhone 11 Pro Max, I jumped on the 13.4 beta train and am seeing pretty normal battery drain from a beta.

Lot better than mine. I was leaving off the charger overnight many times, I'd wake up to still 100%, maybe 97-98% on other days for some reason.
Not anymore since the LAST update, in 6 hours I'd wake up to 93-94%. I'll have dig deep in the settings to see what is going on..but I don't have apps open in the background. Ugh.

 

[macintoshmac]

Standby time has been the best for me of any iOS 13 release. 15 hours and still 99% battery life. 👍🏼

These things should never be spoken out loud. If jinxed, you will see a drastic reduction of battery life in the next version.

It's so random that it boggles my mind.
Just last night I grabbed it off the charger at 100%, I only went on Safari for 4-5 minutes. In that tiny amount of time, the % dropped to 97% Again, I know this is a 5 year old device, but..the severe battery drain started probably in the 13.1 update, but I really noticed it after the late Jan. 13.3.1 install.

**AND another issue, annoyance. Siri is constantly being triggered now. It is near my TV and I know certain words would turn this on (ex. if the news mentioned "Syria" - yeah thats a popular trigger).

But this is also so random, I would rewind my DVR to hear what might turn Siri on...nothing on the TV that remotely sounds like "Hey Siri." (And Siri on my ipad wont go off again) my iPhone is right next to it...that seems to be fine. So odd! Anyway, I turned off "Hey Siri" on the iPad Pro...I'll just hold down home button if I wanna use it.

IP PM - 13.3.1
Couple of new issues that came up during my little get away weekend ...

Camera: Live Shot: Kept running into an issue where the taken shot starts out out of focus, pulls into sharp focus, then starts to go out of focus again. Happens about every third shot. Pain in the ass.

Mail: Swiping right to delete an email fails about 1 in 5 and you can only select Trash to delete.

Messages: MMS: If I choose a non-iOS Message recipient then select several photos from the Photo Gallery, it takes a good while for the message to actually send. These often fail. If I go into the Photo Gallery and select several photos then share via Messages the MMS sends quickly with no failures.

All reported.

Is anyone else having an issue pairing your Apple Watch while the iPhone is on iOS 13.3.1? I can pair it as long as I am on iOS 13.4 Beta.

 

[itsmilo]

When I open „mobile data“ via 3D touch from the settings icon on my Xs Max, it doesn’t load my list of Apps.

My AirPod Pro randomly disappear from the list of known devices and I need to pair them again

 

[Blue Hawk]

This never happened before. What if I wanted to wake up at 1am and my phone skipped 1am and showed 1:01am later?

Well again the problem is the fact that Gmail is only supported in refresh mode with Apple mail, no longer ActiveSync. Googles Sync support was abolished years ago (Jan 2013). Outlook.com and any Exchange based email accts should work real time. Gmail simply is not going to. Best to just use the Gmail app if you have to have that feature. I believe the outlook app works also.

Yes I definitely get notifications from Outlook for my Gmail account.

Since updating to 13.3.1, I have been experiencing massive battery drain due to Siri. I hardly ever use Siri so I have no idea what it’s doing. This is occurring on my iPhone and 2 iPads.

People with the Siri drain; do they have Hey Siri enabled, and the always listening procedure is going crazy and draining battery?

I turned off Hey, Siri because I say seriously often, and it always triggered her.

My Iphone SE frequently creates a screenshot just because I pushed the top button (NOT along with the Home button). Any advice? Is this a "13.3" built-in problem?

I, too, have had insane battery drain thanks to the Apple Music app on both my iPad Pro 12.9 3rd gen and iPhone 11 Pro Max—completely draining batteries when the devices were asleep, both on iOS 13.3.1

Here's the thing, I had background refresh, cellular data, and everything shut off for the Music app—and I don't even subscribe to Apple Music—nor have I ever once used it!

Deleted the app on both devices and have been okay so far since.

Interesting. I actually ran into a similar problem once but with an Android phone - the problem turned out to be a corrupt mp3 file that apparently was interfering with indexing, causing it to run continuously.

Still there are lots of bugs, like sometimes I do not find internet even though my wifi is on and my cellular data is on. The flash message is still blank and the network issue has not been solved yet. The only good thing is that the battery back up has increased. Using I phone X.

Did you try disabling the background refresh from the settings?. It really helps a lot.

IPP 11 13.3.1 using Logitech Smart Keyboard

This device connects via BT. I also have an ASK. The ASK does not trigger this issue It has been getting progressively worse.
I can disconnect the Logitech and in most screens when I access a text field (Game, Safari, other app) the onscreen keyboard will not display. If I toggle BT off, the keyboard will usually display. Other times I also have to reboot the IPP.

Reported. Previously reported under beta.
