Over the years iPhones have gotten faster and faster but their battery hasn’t improved much and it struggles to get you through the day of you are using your phone heavily. Worry no more as there are ways to improve your iPhone’s battery life and make them last longer.
Check Which Apps Are Draining Your Battery
Well ironically closing apps by swiping them away won’t actually improve your iPhone’s battery life but there is a good chance that it will decrease your battery life as iPhone will have to load the applications into memory and relaunch them the next time you access them.
But, since iOS 7, apps can and do use battery life while running in the background. Check which apps are draining your battery by heading to Settings > Battery. Go down the list and see if there are one or two main culprits. This screen shows how much battery power apps have used over the last 24 hours, or the last seven days. You can see how much time apps are running in the background, too. If an application is draining too much battery when you aren’t using it, you can prevent it from running in the background.
Sometimes, an app is just overly battery hungry, and there’s not much you can do but uninstall it. You might want to look for an alternative that’s a little nicer on your battery. For example, you could uninstall the Facebook app and just use Facebook’s mobile site in Safari.
Enable Low Power Mode at the Start of a Long Day
That’s all well and good, but you should seriously consider enabling Low Power Mode yourself if you know you’ll be away from a charger for a while, and you need your iPhone to last as long as possible. Head to Settings > Battery and toggle the “Low Power Mode” switch on to enable it manually.
This mode can be the difference between your phone dying in the middle of the day and lasting all day.
Tweak your iPhone’s Settings
You can tweak your iPhone’s settings to save power in some other ways, too.
For example, if you never use Bluetooth accessories with your iPhone, disable the Bluetooth radio and you’ll save some power. Reducing your screen brightness and ensuring the screen turns off immediately will save you power, and so will reducing push notifications and limiting the apps that can access your location through location services. Having your iPhone use manual refresh for email instead of automatically checking for new emails on a schedule can also help.
Enabling Airplane Mode can also help, assuming you don’t need phone calls, text messages, or data. If you’re travelling quickly–for example, in a car on the freeway or a high-speed train–your phone has to constantly hand off to new cell towers and that can use quite a bit of power. Having a weak cellular signal can also force your phone to scan for a stronger signal, using more power than it normally would.
Take Care of Your Battery
There is a lot of conflicting information about how to take good care of your battery and increase its lifespan.
Well the important thing is that if you can help it, keep your battery charged between 50% and 100% most of the time. You shouldn’t let your iPhone drain to 0% battery too often. Either-though it’s okay to do it occasionally. Also leaving your iPhone in a hot location such as direct sunlight is bad for your battery. Leaving the battery sitting at 0% for a long time is also bad, so you should try to recharge it as soon as possible when it dies.
Apple doesn’t make it easy to see how healthy your battery is, as this information isn’t displayed on iOS. However, you can install the Battery Life app on your iPhone or install the CoconutBattery application on a Mac to check the battery health of a connected iPhone or iPad.
Buy a Battery Case
Want longer battery life? Get a good battery case. Battery cases are exactly what they sound like: cases for your phone, with an extra battery in them that prolongs your iPhone’s life. It’s like an external battery pack, but you can leave your iPhone in that case all the time, so it’s much more convenient and portable–and doesn’t require fiddling with cables
This is the only way to truly increase your iPhone’s battery capacity. The case might make your iPhone a bit thicker and heavier, but it can also make your iPhone’s battery last twice as long. If you ever want a thinner phone, you can always take the phone out of the case. (And actually, there are some great battery cases on the market these days, which don’t increase the bulk of your phone nearly as much as you’d think.)
Get More Convenient Chargers
If you don’t want a battery case, you can still make sure you strategically place chargers everywhere you need them, so you can top off whenever you want. You don’t have to be at a power outlet or computer to charge your iPhone. For example, you can get a car charger and charge your iPhone conveniently whenever you’re in the car.
You can also buy an external battery pack and take it with you, ensuring you’ll always have a way to charge your iPhone if you need more battery power–even if you’re out in the middle of the wilderness with no other sources of electricity. Just keep the battery pack charged and take it with you. Battery packs can be used to charge other phones and portable devices that be charged via a USB cable, too.
And, of course, make sure you have enough Lightning cables, so you’re never stuck near an outlet without the actual cable. You can get great third-party ones from Anker pretty cheaply, so you have one everywhere you need it–your car, your backpack, your office, and everywhere else.
