The iPhone 5 iOS 10.3.3 update is small upgrade but tiny iOS updates can have an enormous impact on a device’s overall performance.
Apple’s iPhone 5 is an old smartphone and that puts the spotlight on each update Apple releases for the former flagship. That includes maintenance releases like iOS 10.3.3.
iOS updates for older devices can have a dramatic effect on performance. Sometimes that effect is positive. Sometimes, unfortunately, it’s negative.
Apple’s latest iPhone 5 update, iOS 10.3.3, is a bug fix update but those of you thinking about downloading the firmware should be extremely careful, especially now that the iOS 10.3.2 downgrade path has closed.
If you’re coming to iOS 10.3.3 from something older than iOS 10.3, you can expect your update to be massive (several hundred MB) 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 10.3.3 update’s performance and it will guide you through some of the key things to keep in mind as we push toward Apple’s next iOS release.
We’ll continue to update this roundup with new details as we get them so keep an eye out for frequent changes.
Quick iPhone 5 iOS 10.3.3 Review
We upgraded directly from iOS 10.3.2 and the download and installation took us approximately 10 minutes to complete.
If you're coming to iOS 10.3.3 from iOS 10.3.1 or something older, your download/installation is going to take a few minutes longer thanks to the updates you skipped.
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.

We've been using the iPhone 5 iOS 10.3.3 update for a few weeks now and the software still feels pretty stable on our device.

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 10.3.3 causing you problems.
We've tested the iPhone 5's iOS 10.3.3 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 still haven't noticed any on iOS 10.3.3.
The iPhone 5 still feels pretty fast with iOS 10.3.3 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.
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 approach its fifth birthday.
The update is solid thus far but you'll definitely want to take a cautious approach, particularly if you're having a good experience on your current version of iOS.
