Apple Ios 10 2 1 Should You Upgrade And What S Included

Should You Upgrade Your iPad or iPhone to iOS 10.2.1?

The 10.2.1 update is relatively small, coming in at 72 Mbs. Users can download the latest iOS update by launching Settings > General > Software Update. This took about 15 minutes to download and install on an iPhone 6s. Although this is a recommended update, make sure you perform a backup just in case. I personally like waiting a bit just to see if early adopters come across any show stoppers. Apple’s mobile OS has become just as complex and targeted as its desktop sibling, and the company throws a lot of human resources into maintaining it. That said, there is always a chance of something going wrong. Here is a detailed list of what’s new and fixed in in iOS 10.2.1.

Conclusion

There is nothing particularly dramatic or must have in a minor point update such as iOS 10.2.1, but I think that’s a good thing. Since becoming an iPhone user, I have appreciated the stability of the platform, especially the consistency in regards to performance with each update. That said, you won’t regret waiting it out a bit, and see how fellow users handle the update before taking the plunge yourself.
