18 Hidden iOS 9 Features That Will Change Your Life

If you're on the go and see no charger in sight, go to Settings > Battery > and turn on low power mode. This temporarily reduces power consumption — a great solution for when you need it the most. Bonus: if you reach the 20 percent battery level, a notification will pop up asking if you'd like to use low power mode.

Finally, when you press the shift key, a lowercase keyboard will appear so you can differentiate between upper and lower case.

Going into Settings can be a dark hole, but now you can search specific terms like "vibrate" and get to what you need much faster.

Swiping left now pulls up Proactive, a feature that gets to know how you use your phone and suggests actions for you. For example, it can tell who you text the most and will have that contact ready for you to text.

Here's another reason to maybe give Apple Maps a chance: the app now has public transit directions that should make it easier for you to get to places if you're in a city.

The News App on iOS 9 might become your favorite Apple app, one that you won't want to delete. You can pick your favorite topics and news outlets to follow and browse through the latest stories.

Your favorite kinds of photos — selfies and screenshots — finally get their own albums so they're easier to find.

Ever get redirected to another app and wish you could quickly go back to the original app without tapping the home button? There is now a dedicated Back To button on the top of an app, so you can go back to the one you started in.

Sometimes, you really need to use a desktop version of a website because the mobile one is just too clunky. To do this, just hold down the refresh button and this option will appear.

While you've been able to see just which apps consume a lot of your battery, you can now also find out how long you actually stared at and used each app.

Available only in Mail, you can attach a photo and do several actions with it just by by pressing down on it and choosing "Markup." You can draw in different colors, add a signature, place a text box, and magnify a certain part of your photo.

Losing WiFi is annoying, but having to turn it off before your phone connects to a cellular network is more annoying — not anymore though. WiFi Assist, which is automatically turned on when you download iOS 9, will do this feature for you.

Instead of having to tap on every single photo, you can simply press Select and drag your finger across as many photos as you want.

If you're hands are occupied, you can now set up the "Hey Siri" function and use Siri hands-free, without being connected to a power source.

It's not a video message, but you do get the option to send a message to a friend who's missed your FaceTime call.

Another new folder comes to Photos, specifically so you can hide private photos from your regular Camera Roll during all those times someone goes through your phone.

To hide a photo, just tap on a photo in your Camera Roll, click the share button, and at the bottom you'll see a Hide button.

Now, when you plug in your headphones, an app will appear that will suggest some sort of audio usage — like Music.
