9 Things to Know About the iPhone 6 iOS 10.2.1 Update

The iPhone 6 iOS 10.2.1 update is now a little more than a week old and today we want to walk iPhone 6 users through the most important things to know about the iOS 10.2.1 update as we cruise into the month of February.

In January, after a stint in the company’s beta process, Apple released its iOS 10.2.1 update for iPhone 6 and iPhone 6 Plus models around the world.

As expected, the final version of the iOS 10.2.1 update is a small maintenance upgrade that brings bug fixes and security patches for potential exploits. iOS 10.2.1 is small but it’s an important update for the former flagships.


If you’re coming to iOS 10.2.1 from iOS 10.2, expect a small download. If you’re coming from something older like iOS 10.1.1 or iOS 9, your iPhone 6’s iOS 10.2.1 update will be much bigger. You’ll get everything from the previous iOS updates baked in.

With the smoke from the release starting to settle we want to take a close look at the iPhone 6 iOS 10.2.1 update.

This roundup includes our updated impressions of the software, some tips to help you get the most out of iOS 10.2, and a look at iPhone 6 iOS 10.2 problems.

We’ll continue to update this page as we push away from the release date so check back for regular changes.

Before we get into a quick look at the update's performance, a quick note about the iOS 10.2.1 download and installation process on the iPhone 6.

The iPhone 6 iOS 10.2.1 update is a small one, it's only a few MB, and it should only take you a few minutes to download over a fast Wi-Fi connection and install. From start to finish the download took us about six minutes to complete.

We've been using the iPhone 6 iOS 10.2.1 update for a little over a week now and we've been taking a close look at a few key areas including battery life, connectivity, and UI speed. Here's what we've learned after spending a week with the iPhone 6's iOS 10.2.1 update.

We haven't noticed any abnormal battery drain. Our iPhone 6 (AT&T model) is holding a solid charge and we haven't experienced the weird "30%" battery bug that's popped up for some iPhone 6 users.

If you recently installed iOS 10.2.1 and you are noticing issues with your iPhone 6's battery life, give it a couple of days. It can sometimes take a few days for the battery to settle down. 

We've tested the iPhone 6's new update with several ISPs, routers, and Bluetooth devices. We haven't run into any issues yet but that could change down the road. AT&T's LTE and 4G networks are working properly as well. 

We haven't noticed any random reboots and the phone's UI appears to be fast. Animations and transitions are fluid and we haven't encountered any weird lag or sluggishness when opening folders, apps or Control Center. 

The iPhone 6 iOS 10.2.1 update's performance is holding up as we make our way into the month of February. And given what's on board the update (bug fixes and security patches), it's certainly worth a look if your iPhone 6 is already on iOS 10. 

If you're on an older version of iOS like iOS 9 you might want to wait a few days so you can gather a little more feedback about performance. 

If you need help to one side of the iOS 10.2.1 fence or the other, please take a look at our list of reasons. It'll help you make a decision today.
