10 Things to Know About the iPhone 6s iOS 9.2.1 Update



A new update for Apple’s iPhone 6s is here and today we want to take a look at the most important things you need to know about the iPhone 6s iOS 9.2.1 update including a look its problems and the update that could replace it.

iPhone 6s users first got a taste of the iOS 9.2.1 last year after Apple released it into its beta programs for developers and the public. The iOS 9.2.1 beta confirmed the update but it didn’t confirm an official release date.

In mid-January, after a short stint in beta, Apple pulled the iOS 9.2.1 update out and released to iPhone 6s users around the world. The iPhone 6s iOS 9.2.1 update is now available via your Settings or through iTunes.


The iOS 9.2.1 update is an incremental update which means it comes without glamorous features and enhancements. Instead, it’s focused on performance.

Apple’s latest iPhone 6s update is small but it’s still important and that’s why we want to take a close look at the essential details.

This iPhone 6s iOS 9.2.1 roundup takes a look at the update’s performance after a few days of use, lingering problems, new iOS 9.2.1 problems, iOS 9.3, and more.

Keep these details in mind as we push deeper into the year toward the next iOS 9 release for Apple’s current flagship.

iPhone 6s iOS 9.2.1 Review

iPhone 6s iOS 9.2.1 Review

We've been using the iPhone 6s iOS 9.2.1 update since its release and we've found it to be a solid performer thus far. 

After spending three weeks with it, the iPhone 6s iOS 9.2.1 update is still performing at a high level on our versions of Apple's flagship. (We're testing the iOS 9.2.1 update on an AT&T and Verizon model.)

Battery life continues to hold up well and we're still getting a full day of use when using a mixture of Wi-Fi and LTE connectivity. If you do run into battery issues like some iPhone 6s users have, take a look at our fixes for iOS 9.2.1 battery life woes.

LTE, Wi-Fi and Bluetooth are all strong, our apps are behaving at the week mark, and we haven't run into any experience-breaking issues with the software. 

The keyboard lag that appeared shortly after the installation is still absent and the iOS 9.2.1 update is still fast and fluid on the iPhone 6s. 

At this point, our stance hasn't changed. Most of you will want iOS 9.2.1 (bug fixes, security enhancements) but if you're feeling leery, take your time. iOS 9.2.1 will probably be around for a few more weeks at least so you can be patient.

      Yep same here. This fix eats battery and I can’t figure out why. I’ve reduced everything turned apps off, reduced light, etc and nothing seems to work Sort it out Apple!!!

    Ever since the update, I’ve been having issues with text messages disappearing and never sending, and apps crashing. I hate it.

    could be -that battery is dying – if you are viewing this webpage (dozens of pages – actually) via your phone – since it is ad heavy and the “slide show” does not help … so really there are about 1000x more ads and clicks than should be required from any legitimate site, though their advice appears sound, maybe clean up your site, guys!

    best ios 9 update till date… for the first time i feel the os is smooth across and the stutters on my ipad mini2 have gone!! even my old iphone 4s seems to have got rid of the laggyness that was there earlier (9.1~).. i guess credit must be given to the plaintiff who is sueing apple for slowing older iphones thru updates.. they have learnt the lesson and sort of smoothened out the os in 9.2.1… the os is smooth overall and across devices.. if you are on iOS 8.3 or more then u should consider upgrading to 9.2.1 before iOS stacks up 9.3 and you no longer get the option to download the 9.2.1 after that!
