Don't Install It If You're Worried About Problems
If you're having an excellent experience on iOS 9.2 or older, you might want to consider holding off on the iOS 9.2.1 update. At least for now.
iOS 9.2.1 comes with some important features but it also, according to its users, brings some problems along with it. We're already hearing about issues with battery life, Wi-Fi, Bluetooth, Apple Music, and that pesky iPhone 6s battery pecentage bug. To name a few.
The list of iOS 9.2.1 problems will surely grow as more iPhone and iPad users discover it lurking on their device.
If you're feeling comfortable with your current update, sit back and wait for more iOS 9.2.1 feedback about your device to arrive.
Apple's cooking up a much bigger iOS 9.3 update and many of you might be better off waiting for that update to arrive before making a change to a new piece of software.
Remember, you can't go back to anything older than iOS 9.2.1 at this point so you need to be confident in your decision to upgrade.
