iOS 9, Apple’s latest mobile operating system for iPhone, iPad and iPod Touch, will be available as a free update tomorrow, Sept. 16th. If you’re skeptical on whether or not it’s worth it to upgrade, here’s a few reasons why you’ll love the new update:

New Features

iOS 9 is packed with new features, from a vastly enhanced Maps app to a smarter Siri and even a brand new curated News app. Siri has been redesigned and offers a wide array of new capabilities. Multitasking has been redesigned and Apple has built in incredible split-screen multitasking capabilities for iPad.

Smaller Update Sizes

In years past, many users had trouble updating iOS because their storage was full or nearly full. By reducing the size of the packaging components and just letting you install necessary files, Apple was able to shrink the size of the iOS 9 install package by over 3.5x compared to iOS 8. Remember, updating your device's iOS through iTunes takes far less available storage than updating directly from the device.

Performance and Battery Enhancements

iOS 9 is much more energy efficient than iOS 8, providing up to an additional hour of battery life across the board. There’s a new battery management section in Settings, including a Low Power Mode that extends battery life even further. All the apps now take advantage of a new Apple technology called Metal, which makes more efficient use of the CPU and GPU. This means Email, Messages, web pages and PDFs render faster and overall performance is improved, with faster scrolling and smoother animations.

More Secure

Apple has built-in new two-factor authentication options and now requires a 6-digit passcode for TouchID devices, ensuring better security and more protection for your sensitive data.

iOS 9 is Smarter

iOS 9 has some incredible built-in predictive features that anticipate actions you might want to do. For example, when you connect to your car’s Bluetooth system, iOS 9 suggests you open the Music app and gives you an ETA to your next destination based on traffic. Another example of predictive tech in iOS 9 is with emails in the Mail app. iOS 9 pulls important information from your email and adds intelligent suggestions in other apps, such as suggesting who an unknown caller might be, or adding a calendar event automatically.
