8 Things to Know About the iPhone 5 iOS 10.3.4 Update



The iPhone 5 iOS 10.3.4 update is small upgrade, but even tiny iOS updates can have an enormous impact on a device’s overall performance.

The iPhone 5 won’t get iOS 11iOS 12, iOS 13, or any future iOS updates and that puts an enormous spotlight on the device’s iOS 10.3.4 update.

iOS updates for older devices can have a dramatic effect on performance. Sometimes the effect is positive. Sometimes, unfortunately, it’s negative.

Apple’s released a surprise iOS 10.3.4 update for the iPhone 5 and it comes with a key bug fix. It’s an important upgrade for those still hanging onto the iPhone 5, but those of you thinking about downloading the firmware should be extremely careful. Once you download iOS 10.3.4 on your phone you can’t go back to anything older than iOS 10.3.3.

That said, most iPhone 5 users will want to download iOS 10.3.4 because key functions like the App Store and iCloud will stop working on November 3rd. This due to a time rollover issue.

If you’re making the move to iOS 10.3.4 from the iPhone 5’s iOS 10.3.3 update, you won’t need to clear out a ton of space on your device.

If for some reason you’re coming to iOS 10.3.4 from something older than iOS 10.3.3, you can expect your update to be massive (several hundred MB or more) thanks to the features and fixes from iOS 10.3 and any other iOS updates you missed along the way.

This roundup will take you through our impressions of the iPhone 5 iOS 10.3.4 update’s performance. It will also guide you through the iOS 10.3.4 problems plaguing iPhone 5 users, fixes for iOS 10 problems, everything you need to know about the iOS 10 downgrade, and some information about the iOS 10.3.3 jailbreak.

iPhone 5 iOS 10.3.4 Impressions

iPhone 5 iOS 10.3.4 Impressions

We upgraded directly from iOS 10.3.3 and the download and installation took us about 10 minutes to complete. 

If you're jumping up from iOS 10.3.1 or an older version, your iOS 10.3.4 download/installation is going to take a little bit longer. 

We recommend putting aside 15-20 minutes of quiet time so that you can monitor the process. You shouldn't anticipate any problems, but there's always a chance for a hiccup. 

For more on the iOS 10.3.4 download and installation process, take a look at our full walkthrough.

We've been using the iPhone 5 iOS 10.3.4 update for several months and the software still feels pretty stable on our device. 

The iPhone 5's battery continues to work miracles. We haven't noticed any abnormal battery drain during our stay on iOS 10.3.4.

If you do start to notice weird battery drain on your device, take a look at our list of tips. Chances are, it's not iOS 10.3.4 causing the problems.

We've tested the iPhone 5's iOS 10.3.4 update with several different routers (including mesh Wi-Fi service eero) and Bluetooth devices. We haven't noticed any major issues. AT&T's LTE and 4G networks are also behaving normally. 

Random reboots were an issue for us on iOS 10.2.1. Our iPhone 5 also rebooted itself several times with iOS 10.3.2 on board. We haven't noticed any issues on iOS 10.3.4. 

The iPhone 5 feels pretty fast with iOS 10.3.4 on board. Animations and transitions are fluid and we haven't experienced any lag when opening up Control Center. We haven't noticed any lag when opening up and closing folders either.

That said, we've seen some clunkiness when opening up applications and when using the keyboard, but it's not as bad as it was on iOS 10.2.1 and older versions of iOS 10.

The device obviously isn't as fast as the iPhone 7 or iPhone 6s, but it's still hanging in there as we close in on the end of 2019. 

The iOS 10.3.4 update is running well on our device, but you'll definitely want to take a cautious approach, particularly if you're having a good experience on your current version of iOS.

The iPhone 5 probably won't get any more iOS updates so you'll be on your own if you run into problems.

    After installing 10.2.1 on my iPhone 5s I started getting random reboots. At least 10 per day. If plugged into the charger, the reboots seemed to go away.

    Hi guys,
    I am using iPhone 5s with ios 9.3.3. I am getting reminders to update to whitetail 10.2.1 I’m not sure though, if I should go for an update or not since Internet is poisoned about 30% battery bug in ios 10.
    I’m new to iPhone, have almost no past experience of ios. As of now I am pretty satisfied with ios 9.3.3 just sometimes it becomes difficult to click on( x) while trying to close search box with some other minor hiccups, don’t know if it’s a software issue or hardware on my device.
    I’m kinda liking the health app. Although it is not measuring the floors climbed while it’s counting the steps taken. I am told it will count the floors climbed after I updated to 10.2.1 which kind of sounds weird.
    Please suggest me the right course of action. By the way what’s Jailbreak?
    Hoping to hear from you soon.

      Try a hard reset, hold down the power and volume buttons until you see the apple logo (~10 seconds). Just a suggestion, I don’t know if you’ve tried it yet but it worked for me

    I’m wondering if the disappearance of my toolkit with calculaor, flashlight, etc that used appear on first opening with an UP Slide before entering passcode had anything to do with the 10.2.1 software?

    The only thing I get now when I Up Slide on opening is a Music tool that does absolutely nothing for me as I don’t keep music on this phone.

    I can’t get rid of it no matter what I try, and I don’t know where to find the calculator, flashlight etc.

    I feel like I Apple just took my Swiss Army knife. grrr.

    WARNING !!! do NOT update the latest software for iphone if you have an iphone 5. Update 10.3.1 will continually ask you for to enter your passcode whether you have ever had one or not. It will not restart without one. I contacted Apple eventually through their help web site and although helpful at first and promising to call me back if we got cut off while they spoke to higher authority for a solution. THEY DID NOT. They came back after the first referral saying they needed at least 30 mins or so for me to hold on. I did and got cut off. No follow up and now the help support site seems to have crashed and even blocked my job referral email link they sent me advising me to find an alternative solution!!
    The only solution offered was to reformat and clear my phone as it had to have a passcode to unlock it after the update. I have had my iphone 5 since they first came out and it has never been locked or had a passcode or a finger print (they kept repeating this question) used.
    Not sure what to do now so I will go into an APPLE store tomorrow and hopefully they can either have found a fix for this problem or restore my phone to 10.3 which was working fine! Obviously I do not want to loose all my data and more importantly my photos of my new granddaughter who visited the other week.

      I have the same problem and the same attitude! I turned off the passcode several months ago but after an update a week ago my iphone 6 is requesting a passcode! I still remember the one and only passcode that was TURNED OFF some time ago and it doesn’t fit. The only way out for now is to restore the phone and to loose all data… That’s what two of my friends did in similar situation. I switched to my very old samsung for now still hoping that Apple will admit the issue and find the way out, but it is a very thin hope…. I even reported the bug on their site, but there is no answer, nothing. Apple has become a huge disappointment :((((( Do they care about their clients any longer?

    I just updated my iphone 5s (on 18th April 2017) and after about half an hour of working normally, the phone is completely dead. It will not charge. I think it’s stuffed! Built in obsolescence?

      I have a i phone 5s that went dead after I took it off the charger toke it to my phone company because I have apple care they were willing to replace it took a few days to get new one. This happened not long after I had updated to 10,3,1. New phone didn’t last a week. This time I toke it to apple store where they replaced it again. New phone didn’t make 24 hours, back to apple store this time another tech again replaced my phone after conversation with tech he told me he had seen 5 or six 5s with this same problem in the last 2 weeks. After about a week this phone to packed it in by now I knew how to do a hard start so I got through the week as I don’t live near apple store. I might add this phone to seemed to crap out not long after I updated to 10,3,1. I/m 3 hours from apple store so I had to wait till last Saturday to get it replaced. Different tech again this time who didn’t want to replace it so we restarted it like it was a new phone, didn’t make 24 hours before it crapped out again. Put up with it for a week, now I’m PISSED!!!!!! SO back to the apple store again tomorrow.

    First off I would like to say great blog! I had a quick question in which I’d like to ask
    if you don’t mind. I was interested to find out how you center yourself and clear your
    head prior to writing. I’ve had a difficult time
    clearing my thoughts in getting my thoughts out there.
    I do enjoy writing however it just seems like the first 10 to 15 minutes are lost just trying
    to figure out how to begin. Any recommendations or hints?

    Did the update to my Iphone 5 last evening. Since then none of the alerts will work. I have checked the mute status, airplane mode, and Do Not Disturb mode is not activated/on. I use this phone for work, this is not a good experience!

    After I updated iOS 10.3.3 to iOS 10.3.4 my iPhone 5 started to work significantly slower in a week or so after the update. That’s the REAL reason of this update.
