15 Easy Ways To Extend Your Phone’s Battery Life


If you’ve had the same smartphone for over a year, the battery probably isn’t what it used to be. And no, you’re not just paranoid. According to two 2014 Nature Communications papers, the lithium batteries used to power our devices wear down over time. Apple even admitted to slowing down older iPhones to compensate for degraded batteries.

Sure, you could always pony up for a new battery (or buy a new phone altogether). But if you’d rather save your cash, there are plenty of ways to get some extra juice out of your current device. Try these 15 tips and tricks to extend your battery life.


low battery on phone

This might seem obvious, but most people don’t think about using battery saver mode until their phone is already about to die. Apple’s “Low Power Mode” switches on automatically when you hit 20 percent, but you can head into Settings > Battery to switch it on whenever you want or add it to your Control Center for easier access. Most Android phones offer a similar feature that can be toggled on at any time, which should help your device conserve some power and keep you going all day.


charging phones

When you do have to recharge your phone, there are some precautions you should take to make sure you don’t degrade the battery any more than necessary. First, only use fast charging when you’re in a rush. While this feature can quickly top off your battery, it also wears down the battery faster than regular charging. If you have time to spare, it's better to use a regular old charger. Second, don’t charge your phone overnight—it only takes a few hours to get a full charge, and the rest of the time spent plugged in will only hurt your battery life in the long run.



If Bluetooth and Wi-Fi are enabled, but you’re not connected to anything, your phone will waste battery trying to find a new connection. Instead, the next time you’re out of the house, try switching off Wi-Fi to keep your battery going a little longer. The same goes for Bluetooth. Whenever you’re not connected to a wireless speaker or headphones, just toggle it off. You can control Bluetooth and Wi-Fi from the quick settings menu on most phones, so extra battery life is just a swipe away.


Free wi-fi sign

On the other hand, if Wi-Fi is available, you should be using it. Not only does Wi-Fi save data, it uses less battery life than a cellular connection. Don’t forget to switch on Wi-Fi at home, and don’t be ashamed to ask for the internet password if you’re at a friend’s place or a cafe.


Airplane mode

If your battery is starting to run low you might want to consider switching on Airplane Mode, which will turn off a bunch of features that use up power. That includes Bluetooth and Wi-Fi, but if you need either of those, you can always turn them back on manually without leaving Airplane Mode.


Bright iphone screen

When it comes to using up smartphone battery life, one of the worst culprits is the display: Whenever it’s on, you’re losing precious power. One way to get around that is to lower your screen brightness from the quick settings menu. Most phones adjust the brightness automatically depending on the current lighting, so you may have to do this every time you switch on the screen. Still, it’s worth it if you get even a few minutes of extra phone time as a result.


Facebook on phone browser

Facebook’s app is one of the biggest battery hogs around, but there’s an easy way to get rid of the app without missing out on your aunt’s latest status update. You can access Facebook from your smartphone’s browser for a nearly identical experience. (You can even get notifications.) For quick access, try bookmarking Facebook.com and setting it as a home screen icon to replace the app.


google maps on smartphone

Some apps (like Google Maps) really do need to know where you are to function, but others (like Facebook) probably don’t. Besides the issue of privacy, turning off location services for apps that don’t need it can help extend your battery life, since your phone won’t be working overtime to track where you are. On an iPhone, just go to Settings > Privacy > Location Services to see which apps are tracking you and toggle off the ones that shouldn’t be. Android offers a similar feature, just head to Settings > Security & Location > Location.


Hands using phone

Background app refresh is another potential battery waster to consider, though it’s not the worst offender. This feature lets apps update in the background so they’re ready to go when you need them. That might sound bad but it only happens at ideal times, like when you’re already on Wi-Fi. Still, if you want to disable it just head to Settings > General > Background App Refresh to switch it off. Pulling this off is a little trickier on Android depending on your phone model, but you should be able to find the option by heading to Settings > Data Usage and then poking around.


iPhone control center

This one is for iPhones only. Apple’s AirDrop feature is a useful tool for quickly sharing pictures and files with the people around you, but it can be a battery waster too. To turn off AirDrop, just swipe open Apple’s Control Center and tap on it to the feature off. You can also find it in Settings > General > AirDrop.

Another iPhone-only trick for saving battery life is to turn off Spotlight, Apple’s intelligent built-in search. Spotlight tracks your activity to show you the best possible results when you search for something on your phone. That’s useful, but it’s also a battery waster. Turn it off by heading to Settings > General > Spotlight Search. From there, you can uncheck items from a list of activities Spotlight tracks (Apps, Contacts, Music, etc.), or just remove them all.


Siri on the phone screen

Being able to activate your phone’s AI assistant with a voice command is great, but it comes at a price. If your iPhone or Android device is always listening, that means it’s always wasting battery power. To turn off Hey Siri, head to Settings > Siri & Search and then toggle off “Listen for ‘Hey Siri.’” On Android, open the Google app and tap the menu icon in the top left corner. Then select Settings > Voice > “Ok Google” detection. You should see a toggle labeled “‘Say Ok Google’ any time.” Switch it off and you’re done.


smartphone screen

Widgets and moving wallpaper are great for sprucing up your smartphone, but they also waste a bunch of battery life. If you’re worried about making it through the day without running out of juice, switch to a simple still background image and delete any widgets that update automatically. On an iPhone, you can also remove any visual effects by heading to Settings > General > Accessibility > Reduce Motion. Android has a similar option for in-app animations, too: Just head to Settings > Developer options and then disable “Window animation scale,” “Transition animation scale,” and “Animator duration scale.”

It’s hard to remember a time before automatic app updates, a time when you had to manually update each app as improvements rolled out. But if you’re serious about extending your battery life, killing those automatic updates may be your best option. Switching off automatic app updates reduces the amount of activity happening in the background on your phone, which means less power is wasted on non-essential actions. To turn it off on your iPhone, head to Settings > iTunes & App Store and then toggle off Updates under Automatic Downloads. On Android, open the Google Play Store and tap on the menu icon in the top left corner. Then, hit Settings > General > Auto-update apps and switch it off.

Finally, if you’re still not getting enough life out of your smart battery, one power-hogging app may be to blame. You can sniff out the culprit by checking your smartphone’s battery usage and then deleting the worst offenders. On iPhone, head to Settings > Battery and then scroll down to see which apps are using the most power. Android works the same way. Go to Settings > Battery > Battery Usage and you’ll see a list of the apps and services that are wearing down your battery.

Stouffer's Has Invented a Mac and Cheese Dispenser for National Mac and Cheese Day

The Stouffer's mac and cheese dispenser appears destined for college dorm rooms everywhere.
The Stouffer's mac and cheese dispenser appears destined for college dorm rooms everywhere.

Though preferences vary from Kraft to Stouffer’s to homemade, macaroni and cheese has remained a go-to pasta dish for generations. Now, Stouffer’s appears to be taking distribution of this comfort food staple to the next level by introducing a mac and cheese tap it wants to install at commercial establishments.

The announcement, which conveniently comes just prior to National Mac and Cheese Day on July 14, is a glimpse into the future of on-demand pasta. The tabletop dispenser has an internal heater to keep the pre-made mac and cheese warm. With a flick of the wrist, it allows globules of warm, cheesy sustenance to ooze out of the tap and into a bowl or as a topping. It might be best described as a nacho cheese dispenser, only with pasta noodles.

Stouffer’s offered a primitive view of its mechanism on Twitter:

Stouffer’s, which normally peddles frozen mac and cheese in grocery stores, is soliciting suggestions for where their mac tap should wind up. Homes, gas stations, sports arenas, and weddings are apparently all on the table. The company says it’s aiming for a launch this year and will consider sites based on that consumer feedback.

There seem to be logistical hurdles that Stouffer’s has yet to publicly address. The chances of cheese and pasta clogging the mechanism might be a common occurrence, and the machine will almost certainly require daily cleanings. Such maintenance might result in a plight similar to those frequently unavailable McDonald’s McFlurry machines.

On social media, however, at least one rival cheese baron was impressed. In response to the announcement, Velveeta Tweeted a one-word response: “Respect.”
