iPhone 5 iOS 10.3.1 Update Review

The iPhone 5 iOS 10.3.1 update is a small one (if you're coming to it from iOS 10.3) and it'll only take you a few minutes to download and install. It took about 15 seconds to download and another five to install. 

If you are coming to iOS 10.3.1 from iOS 10.2.1 or something older, your download/installation is going to take a lot longer. 

Due to the file system change and the other features on board, the iPhone 5 iOS 10.3 update took about five minutes to download and upwards of 15 minutes to install on our device. That's abnormal for an iOS update and it means you'll need to pay extra attention to the installation process. 

If you failed to install iOS 10.3, we recommend setting aside 30 quiet minutes where you can monitor both the iOS 10.3.1 download and installation without distractions. Moving onto the update's performance. 

We've been using the iPhone 5 iOS 10.3.1 update a little more than three weeks now and the update has been pretty impressive. We're using the update on an aging AT&T model. 

The iPhone 5's battery continues to work miracles. We haven't noticed any abnormal battery drain during our time with iOS 10.3.1.

If you do notice weird battery drain, take a look at our list of tips. Chances are, it's not iOS 10.3.1 causing your problems.

We've tested the iPhone 5 and its iOS 10.3.1 update with several different ISPs, routers and Bluetooth devices. We haven't noticed any major issues during our time with the upgrade. AT&T's LTE and 4G networks are working fine as well. 

Random reboots were an issue for us on iOS 10.2 but we haven't noticed any during our time on iOS 10.3.1. That's a big improvement.

The most noticeable change, outside of the new features, is to the speed of the device's user interface. Animations and transitions are fast and fluid and we haven't experienced any lag when opening up Control Center. 

We also haven't noticed any lag when opening up and closing folders, something we did see on iOS 10.2.1. The movement is crisp. There's still some jaggedness when opening up some apps but hey, the phone is going on five years old.

iOS 10.3.1 is treating our iPhone 5 well though you'll want to approach the update with a bit of caution if you're having an excellent experience on iOS 10.3 or below.
