7 Things to Know About the iPhone 6s iOS 10.2.1 Update

The iPhone 6s iOS 10.2.1 update is a small but important update for the former flagship and today we want to take a look at the most important things iPhone 6s users need to know about the current version of iOS 10.

Last year, Apple confirmed an iPhone 6s iOS 10.2.1 update with a release into its beta program for developers and the general public.

In January, Apple pulled the iOS 10.2.1 update from beta and released it for the iPhone 6s and iPhone 6 Plus.

iOS 10.2.1 isn’t as big as its predecessor (iOS 10.2) but it’s an update you should have your eyes on as we cruise through the month.

If you are coming to iOS 10.2.1 from the iPhone 6s iOS 10.2 update, your download is only a few MB. If you’re coming to it from something older than that, your iOS 10.2.1 update will be much larger thanks to previous versions of iOS.

Today we want to take a look at the most important things you need to know if you’re already on iOS 10.2.1 or if you’re thinking about installing the iOS 10.2.1 update on the iPhone 6s or iPhone 6s Plus.

This roundup looks at the iPhone 6s iOS 10.2.1 update’s performance, the current state of iPhone 6s iOS 10.2.1 problems, and a quick glimpse at what’s next from Apple and iOS 10. Apple’s confirmed a new update that could replace the iOS 10.2.1 release in a few weeks.

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

The iOS 10.2.1 download/installation process took us about seven minutes to complete. We suggest putting 10-15 minutes of quiet time aside to monitor the process for problems. We didn't run into any issues but there's always a potential for trouble.

If you're coming to iOS 10.2.1 from something older than iOS 10.2, put aside 20 minutes or more to get the job done. Again, your update will be much larger.

We've been using the iPhone 6s iOS 10.2.1 update for over a week and the update continues to perform well on our iPhone 6s variants. 

Battery life is holding up and we haven't seen any abnormal drain on the two iPhone 6s models we're using to test the iOS 10.2.1 update. We're still able to get a full day of use when using a mixture of Wi-Fi and LTE. 

If you recently installed iOS 10.2.1 and you're seeing abnormal battery drain issues, give it a couple of days. Sometimes it takes a few days for the battery to settle in. If the problems persist, you'll want to dig into some fixes.

We've also yet to notice the "30%" battery bug that many iPhone 6s users have come across during their time with iOS 10.2 and below.

Connectivity remains stable as we push away from the update's release date. We've tested the phone and the update with several ISPs, routers and Bluetooth devices and we haven't noticed any major issues with our connections. They remain strong and fast.

The iPhone 6s' UI is fast and we haven't experienced any lag, random reboots or freezes during our testing. The iOS 10.2.1 update feels stable and fluid. Its aging like a fine wine. 

So far, the transition from iOS 10.2 to iOS 10.2.1 has been smooth. We haven't run into any significant performance issues at the week milestone.

The update is certainly worth a look if you're running into issues on an older version of iOS 10 or if you're concerned with your devices security. The iOS 10.2.1 update features 13 security patches. 

If you're coming from an older version of iOS, like iOS 9, you might want to snag a second opinion before installing the update on your device.
