In iOS 9, you can view specifics on which apps are using your iPhone’s battery. If you find your battery is draining quickly, viewing detailed battery info is a great way to figure out why. You can see which apps use chunks of your battery life, how long the app was active, and how long the app was running in the background. This is also a great way to see how much time you're spending on a particular app; in case you're still in denial about your Facebook habit.

With a subscription to Apple Music or iTunes Match, you can use the iCloud Music Library. This is an easy way to have access to your music across all of your devices. When your iCloud Music Library is enabled, you can add an Apple Music song to My Music from your iPhone, then check your iPad and the song will be there.

On by default, Safari Quick Search uses search shortcuts to look within websites. Therefore, if you type a website name as a part of your search, Safari will look within that website for what you need. For example, type “Youtube cat video” to show YouTube search results for cat videos. If you’d rather this feature be turned off, here’s how.

With iOS 9, your iPhone looks through the Mail app to let you know who might be calling when an unknown number comes in. This is true for outgoing calls as well; iOS 9 will try to match the number you’re calling with a contact from emails. If this is a function you’d like to turn off, here’s how.

With iOS 9, Apple introduces the iPad to split-screen multitasking. Also called Slide Over, this new function is supported by the iPad Air, iPad Air 2, iPad mini 2, and iPad mini 3 and later. Located on the right edge of the screen and designed to run multiple apps, Slide Over allows you view another app without leaving the one you're in; however, the two applications won't run together side by side unless you have an iPad Air 2 or later. 

If you’re on an iPhone 6, the iOS 9 update likely works wonderfully and does what Apple intended. However, users of earlier models of the iPhone are reporting a major lag in performance since updating. With every software release there are bound to be bugs. If you’re considering reverting to old software, keep in mind that iOS 9.1 will soon be available. If the performance bugs are minor, I recommend you wait; however, if the update has turned your iPhone into a fancy calculator, we’ve got four ways to make it a super computer again.

One of the smaller changes with iOS 9 is the appearance of the keyboard when using the Shift key. Before, the keys were uppercase in appearance and the highlighted shift key was the only way to know you were typing in uppercase. With the update, the keys are lowercase except when Shift is active: the entire keyboard changes to uppercase. This can make it easier to know which case you're typing in; however, if you prefer the previous set-up, there's a simple Settings change to turn the lowercase keys off.

Previously, whether your iPhone was muted or not, Siri's voice would loudly chime. With iOS 9, you can set Siri's voice to mute when your phone, too, is muted. This is easily changed in Settings and convenient when asking the new and improved Siri questions in quieter locations.

Have you ever been watching something on Netflix with your iPhone or iPad only to realize the app was using cellular data instead of Wi-Fi? Most of us do not have unlimited data available, so that can be an expensive mistake. To avoid using data when you don't have to, it's a good idea to prevent data-gobbling apps from accessing data as their default setting. You can do this by turning off cellular data for specific apps, like video and music streaming apps, and changing the frequency with which apps like Mail fetch new data.
