12 ways to make your iPhone's battery last longer

If you dig around in the settings menu, you can see which apps drain the most power. Just tap Settings > General > Usage > Battery Usage. Then, you'll see a list of all the apps you've used in the last day and how much of your phone's battery they've been using.

This is really the first thing you should do if you're low on battery. Simply swipe up from the bottom of your screen and adjust the brightness slider accordingly.

Newer iPhones (iPhone 5s and above) quietly monitor your movement in the background, and integrate that data with Apple's health app. While this can be useful, it's also not necessary and can easily be cut out if you're looking to save some battery life. Head over to Settings > Privacy > Motion & Fitness and tap the Fitness Tracking switch.

The iPhone can automatically update apps for you in the background while you're connected to Wi-Fi, but this can drain your battery. Only do this when you're phone is plugged in, and update your apps manually otherwise. To turn this feature off, go to Settings > iTunes & App Store and then scroll down to Automatic Downloads and switch off the Updates slider.

The iPhone has a feature that tracks your location and the places you most frequently visit so that it can personalize your notifications. But, constantly gathering that location data can run your iPhone's battery down. Navigate to Settings >Privacy > Location Services > System Services > Frequent Locations to turn this feature off.

If your iPhone's battery life is draining more quickly than usual, make sure Bluetooth is turned off. Bluetooth is what lets your iPhone communicate with accessories like wireless speakers and fitness trackers. But, if you're not using any Bluetooth accessories, you'll want to make sure it's switched off by swiping up from the bottom of your screen and making sure the Bluetooth icon isn't lit. Just tap it to turn it on or off.

With iOS 7, Apple added support for "dynamic moving images," or wallpapers that move. You can get a little extra juice out of your iPhone's battery if you use regular stationary images, however. When you're browsing through wallpapers, make sure you're looking through the Stills category instead of Dynamic.

There's some debate as to whether or not this actually helps preserve your battery life, but Cult of Mac makes the case for how switching from "push" to "fetch" could cut down on power usage. With the "push" feature turned on, your phone is constantly listening for new emails and downloading them from the server in the background.

The "fetch" setting, however, tells your phone to ping the server every once in a while to download new emails, meaning your phone isn't always wasting energy by downloading emails in the background. To change this, go to Settings > Mail, Contacts, Calendars > Fetch New Data, and make sure the Push switch is off.

This feature automatically refreshes the content of an app whenever your iPhone is connected to Wi-Fi or the internet. Essentially, this means the apps on your phone are fetching data even when you're not using them, which can cause your phone's battery to drain faster. To turn off this feature, go to Settings > General > Background App Refresh.

There are plenty of apps that may be better suited for your needs than the ones that come with your iPhone, but Apple's own apps are optimized to run smoothly without taking up too much power. If you don't necessarily care about having the best email or calendar app and can make due with Apple's, it might save you some power.

If you're battery is running low, try checking which apps you have running in the background. In most cases, this won't affect your battery too much. But, if you're using one that heavily relies on pulling location data, it could do some damage. One easy way to tell if your location is being used in the background is by checking for the little GPS symbol in the upper right hand corner of your screen.
