Quick iPhone 5 iOS 10.3.3 Review
We upgraded directly from iOS 10.3.2 and the download and installation took us 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. For more on the iOS 10.3.3 download and installation process, take a look at our full walkthrough.
We've been using the iPhone 5 iOS 10.3.3 update for many months 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 the 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 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 won't get any more iOS updates so you'll be on your own if you run into problems.
