How do I get better battery life from my iPhone?
Here are the best ways to improve your iPhone or iPad's battery life, from system-wide settings worth tweaking to third-party apps that you should stop - or start - using in order to preserve battery life. And we also cover desirable accessories that will help.
12 tricks for saving your phone's battery life.Use these tricks to make sure your phone's battery life lasts for as long as possible.
1. Figure out what's sucking your battery.
In Settings > Battery, you'll get an overview of how much battery power each app is using.
Close the apps that are sucking a lot of your power when you're not using them, and consider not using them when your battery is low.
2. Low Power Mode
Low Power Mode can help you out when your battery is at 20 percent or below. It suspends background app refresh and automatic downloads. You can turn on Low Power Mode under Settings > Battery.
3. Fix your auto-lock.
Your iPhone sucks battery whenever the screen is lit up, even when you're not using it. To decrease the amount of time it spends doing this, set your phone to auto-lock as frequently as you can tolerate. Navigate to Settings > Display & Brightness > Auto-Lock.
4. Disable location services.
Some apps consistently track your location, even when you're not using them, which takes battery life. Go to Settings > Privacy > Location Services and select the "While Using" option for all of your apps.
5. Turn of "Push" on your email accounts.
There are two ways you can set your accounts to go about checking for new emails. They can "Push" (check and download in real time) or "Fetch" (check and download every 15 minutes or so). "Fetch" uses less battery power because it pings the server less frequently. Go to Settings > Accounts and Passwords > Fetch New Data and select "Fetch" for each account. If you are really ambitious, you can also select "Manual" and check your emails manually.
6. Turn on auto-brightness.
If your battery is draining quickly, there's a chance your screen is brighter than it needs to be. Auto-brightness will darken your screen as it gets later in the day. Go to Settings > General > Accessibility > Display Accommodations and toggle "Auto-Brightness" to On.
7. Don't use data when you could be using wifi.
Not only is cellular data expensive to use, but it also requires more battery power to access than a cellular network. To turn on wifi, swipe up and select the Wifi icon in the top left box of your Control Center.
8. Turn off background auto-refresh.
Many apps are constantly refreshing and updating their content, even when you're not using them, which eats up battery power. To stop them from doing this, go to Settings > General > Background App Refresh and toggle Background App Refresh to off.
9. When you don't have cell coverage, use Airplane Mode.
If you're in an area without cell service, your device is probably spending a lot of power searching for a signal. If you know you won't be getting signal back any time soon, swipe up from the bottom to open your Control Center and tap the Airplane Mode button in the top left.
10. Make sure your computer is on while it's charging your phone.
If your phone is connected to a computer that is asleep or powered off, its battery won't charge much, and may actually drain. Keep your computer on when your phone is plugged into it.
11.Avoid games and high-impact apps
It sounds obvious to say your iPhone's battery is drained quicker the more you use your phone, but the speed with which it falls from 100 percent to nothing entirely depends on what apps you use.
Some apps burn through your battery much faster than others. Heavy use of the processor and GPU, for 3D games, or the GPS chip, for maps and location-based apps, uses up more energy than reading content in the Books app, for example.
If you play games with rich, detailed visuals, such as Infinity Blade, or 3D racing games like CSR Racing, your iPhone's battery will be drained quickly. So if you're away from a charger and waiting for an important call, playing these sort of games is not a good idea if your battery levels are already low.
If you're on the way home and low on power, reading apps like Kindle or Instapaper won't drain what's left of your battery terribly quickly.
However, it probably wouldn't be a smart move to start playing your favourite TV series, or, worse, the latest 3D gaming blockbuster. In fact, even quite simple games often utilise complex 3D trickery, and so when in the red battery-wise, avoid them entirely.
12.Turn off Location Services
Most of the time it's not iOS itself that's causing the iPhone or iPad's battery to drain quickly, but all the apps that are running on it. There are a number of apps that utilise location services on your iPhone and they can play their part in draining your battery too. It's even more frustrating when it's not obvious why some of them need to know where you are in the first place. To stop apps from using Location Services, tap Settings > Privacy > Location Services and either turn off Location Services altogether (by tapping the slider beside it), or deselect any apps that you don't need to access your GPS.
