Here are the most important things to know about the iPhone 5 iOS 10.2 update and its performance as we enter into the month of January.


The iPhone 5 is getting older which puts greater importance on each update Apple releases for the former flagship. iOS updates for older devices can have a dramatic effect on a device’s performance. Positive or negative.

Apple’s latest iOS 10 update for the device is a big one. The iPhone 5 iOS 10.2 update is much larger than the iOS 10.1.1 update and it brings some notable changes to the aging smartphone.

The iOS 10.2 is now a few weeks old but we continue to see new and important details emerge as we push into the new year.

If you’re making the move from the iOS 10.1.1 update, your iOS 10.2 update will be well over 100MB in size. If you’re coming from something older, you can expect your iPhone 5’s update to be much larger thanks to the features and fixes from previous iOS upgrades.

iPhone 5 iOS 10.2 Update: Impressions & Performance

The iPhone 5 iOS 10.2 update is a big one and it'll take you a few minutes to download and install. It took us about five minutes to download the update over a fast Wi-Fi speed network and about 10 minutes to finish up the installation. 

We recommend setting aside 20 quiet minutes where you can monitor both the download and installation without distractions. 


We've been using the iPhone 5 iOS 10.2 update for just about a month now and the update is, for the most part, holding up. 

The iPhone 5's battery continues to work miracles at the three week mark. We haven't noticed any abnormal battery drain during our time with iOS 10.2. A number of iOS 10.2 users are reporting abnormal battery drain but we haven't seen anything odd on our variant. 

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

Shortly after installing iOS 10.2 on our iPhone 5 we experienced a random reboot. We've seen about five during our three weeks with the update, an uptick from the number we saw with the iOS 10.1.1 update on board. 

UI speed is decent. Animations and transitions are fast and fluid and we haven't experienced any lag when opening up Control Center. The UI still lags when opening up folders and some apps but that's par for the course. Remember, this phone is now over four years old. 

If you're already on iOS 10.1.1, iOS 10.2 and its features/fixes/patches make it worth a serious look. The random reboots are annoying but this appear to be an isolated issue rather than a widespread one. 

If you're on something older than the iOS 10.1.1 update, make sure you dig into more feedback before you make the jump to iOS 10.2.
