  • Reduce the amount of time a battery spends at either 100% or 0% charge, as both extremely high and low “states of charge” stress batteries.

Remove Unnecessary Widgets from the Home Screen

Yes, iOS 14 has excellent widget support! But if you unnecessarily fill your iPhone Home screen with these, it can cause your iPhone 12 battery to die fast.

This is because widgets (such as Weather or News) constantly refresh data to serve you with the latest information. And this has an impact on battery.

To remove a widget: Long press on it and choose Remove Widget > Remove.

Use Dark Mode

Dark mode can significantly (even up to 30%) extend the battery life on iPhone 12.

Start the Settings app and tap on Display & Brightness.
Under APPEARANCE, tap on Dark.tap on display & brightness in iphone settings and select dark
Tips: You can also long-press on the Control Center’s vertical brightness slider to enable dark mode. Additionally, you may add its separate button to the Control Center. Like to use your voice? Ask Siri to enable or disable dark mode.

Activate Low Power Mode

One of your strongest weapons against battery
drain is Low Power Mode. With it enabled, your phone only performs the most essential of tasks, so background activities like downloads and mail fetching are disabled.

Low Power Mode will automatically be engaged when the battery falls below 20 percent, but you can also activate it manually to keep your phone going for longer (though it will only work if your phone’s battery is below 80 percent).

Head over to Settings > Battery > Lower Power Mode and toggle it to on. You will know the feature is activated because the battery icon in the top-right corner will turn yellow.

Adjust Screen Brightness

Smartphone displays are bigger and brighter these days, but those crisp screens keeping you awake at night are murder on your battery life. The good news is you can easily dim that brightness.

First, activate auto-brightness. Navigate to Settings > Accessibility > Display & Text Size > Auto-Brightness and toggle it to on. Your phone will then adjust its brightness based on your current lighting situation. If you have enough light to see, the screen will turn itself down and save battery life.

You can also manually adjust brightness levels in Settings > Display & Brightness, where you can turn on dark mode, but also adjust brightness via the slider bar. A slider is also accessible via the Control Center; pull down from the top-right corner. Press lightly on the brightness icon and move the slider up or down.

Turn Off Location Services

Location services are helpful for apps such as Maps or Find my, but those GPS pings can cause your iPhone 12 battery to die quickly. Turn off location services completely via Settings > Privacy > Location Services and your phone will stop feeding location data to these services.

This, however, will make a number of useful apps stop working. Your weather app won’t know where you are for the latest forecast, and you won’t be able to ask Google for directions based on your current location. As such, Apple provides the option to customize how most apps use location data: Never, While Using the App, or Always. Select “While Using the App” for Google Maps, for example, and the app will only ping your location when you open it, not in the background, draining battery.

Turn Off Background App Refresh

When you close an iOS app, it will keep running for a bit until entering a suspended state. With Background App Refresh, however, those suspended apps can still check for updates and new content—a process that can cause your iPhone 12 battery drain faster.

You can disable Background App Refresh completely or just for certain apps. Navigate to Settings > General > Background App Refresh. Tap Background App Refresh up top to turn it off, or opt to have it happen only over Wi-Fi.

To disable on an app-by-app basis, return to the previous menu and find refresh-heavy apps, like email or social networking platforms. Toggle them off. This shouldn’t have any effect on how the app works, but might take a moment longer to surface new information when you return to them.

Customize ‘Fetch New Data’

Having email on your phone can be super convenient and data fetches mean your inbox is always displaying the most recent messages. But you can customize how these fetches occur so the phone isn’t draining its battery by constantly searching for new messages or calendar items.

Turn off data pushes by navigating to Settings > Passwords & Accounts > Fetch New Data. Here, you can deactivate Push data entirely or choose how often you want your iPhone to check for new content on the various apps that support it.

Cut Down on Notifications

If your screen illuminates with a preview of every notification you receive, it’s consuming power with each text, breaking news alert, or Twitter follow. Cutting down on these interruptions can improve iPhone 12 battery life.

One option is to find a notification from an app you’d like to silence, swipe left, and select Manage. Here you can choose to have the alert delivered quietly, which means it will go to your Notification Center, but won’t show up on the Lock screen, play sounds, or show a banner or badge icon. You can also turn off notifications for this app completely.

Or go to Settings > Notifications and customize how and when specific apps will show notifications.

Turn Off Wi-Fi

Using Wi-Fi is a great way to cut down on the amount of data you use, but it doesn’t do wonders for your battery. Your phone continuously searches for nearby Wi-Fi networks, which is why the list of available networks constantly changes when you’re out and about.

The quickest solution is to shut off Wi-Fi at Settings > Wi-Fi; toggle the switch at the top of the screen to off. You can also do this via the Control Center pull-down; tap the Wi-Fi icon to shut it off. Just remember to turn it back on when you get home or to a location with steady Wi-Fi, lest you use up all your cellular data.

Shut Down Bluetooth and AirDrop

Similarly, Bluetooth and AirDrop are constantly looking to connect, but there’s no reason for them to be active at all times.

Turn off Bluetooth by heading over to Settings > Bluetooth and sliding the toggle to off. Turn off AirDrop by navigating to Settings > General > AirDrop > Receiving Off.

You can also turn AirDrop off from the Control Center. Swipe down from the top-right on iPhone X and above or from the bottom of the screen on older iPhones. Press down slightly on the menu options on the top-left. Tap AirDrop in the menu that appears and choose Receiving Off.

Switch to Airplane Mode

If you’re in a real jam for power, put your iPhone 12 in Airplane Mode, which turns off all your phone’s wireless features. Calls and texts won’t come through, but you can still connect to Wi-Fi if necessary for iMessages and other tasks. The easiest way to do this is to look for the airplane icon in the Control Center and tap it. It’s also accessible in Settings; just toggle it on.

You’ll know it’s activated if an airplane icon appears on the top right.

Turn Off Siri Suggestions

Siri is Apple’s personal assistant,” so on iOS, she will make suggestions based on your activity. If you get coffee most days, for example, Siri may suggest your order around the time you normally place it. That’s great, but she has to do some work in the background to make this happen, which—you guessed it — lead to iPhone 12 battery drain issues.

Go to to Settings > Siri & Search. Under Siri Suggestions, you can enable or disable them in search, in Look Up, and on the lock screen.

Kill Active Listening

iPhone 12 support hands-free Siri, meaning you can say “Hey, Siri” and ask a question without having to touch your device. But that means the iPhone is awaiting your command, so if you don’t use Siri that much, turning off active listening could fix iPhone 12 battery drain.

Go to Settings > Siri & Search, where you can disable “Listen for ‘Hey Siri.'” Instead, you can leave “Press Side Button for Siri” enabled, and still activate Apple’s digital assistant with the push of a button.

Turn Off Automatic App Updates

It’s always a good idea to keep your apps and operating systems up to date. Some updates can help your apps run faster and smoother, decreasing the processing power needed to make them function.

Since iOS 7, Apple has supported automatic app updates, meaning when an app update arrives, your phone will install it in the background so you’re always up to date. That process can cause your iPhone 12 battery to die fast, though. To temporarily turn it off, go to Settings > iTunes & App Store and toggle the switch next to Updates to off.

Remove Motion Effects

There are a number of iPhone features that look cool—motion effects on app icons and dynamic wallpaper, for example—but slowly drain your iPhone 12 battery.

Turn off the motion effects on apps by heading over to Settings > Accessibility > Motion > Reduce Motion, then toggle the switch to turn the feature on. Note, however, that this will also disable screen transitions and effects that dissolve as well as the parallax effect—where your wallpaper, apps, and alerts move with you as you tilt your device.

Dynamic wallpapers, meanwhile, are backgrounds that contain movement and change over time. You don’t have to turn this feature off; just choose a wallpaper that doesn’t move via Settings > Wallpaper > Choose a New Wallpaper > Stills.

Dynamic wallpaper and perspective zoom are automatically turned off when a phone is in Low Power Mode.

Manage Vibrations

Did you know the mechanism in your phone responsible for vibrations can cause your iPhone 12 battery to drain fast? Since the little motor inside the device that is in charge of vibrations requires energy, it may help a bit to silence your phone.

To disable it, head over to Settings > Sounds & Haptics and turn off Vibrate on Sound or Vibrate on Silent.

Tame iCloud

Apple’s iCloud Photos feature will send photos you take on your phone to the cloud, so you can access them on other devices and the web. It’s a nice feature, especially if your phone is lost, stolen, or damaged. But yes, sending those photos to the cloud can cause your iPhone 12 battery to die quickly.

If you need a little extra battery power while you’re out and want to take the risk, disable this via Settings > Photos > iCloud Photos.

Restart Your iPhone Regularly

One easy way to make sure that things work correctly on your iPhone is to restart it regularly. Now, you may ask, ‘how regularly?’ Well! There is no fixed answer, but I like to restart my iPhone once every 2-3 days. This keeps everything smooth.

Place Your iPhone Face Down

Did you know that when you put your iPhone with the screen down (facing the surface), the screen does not illuminate when you receive a notification?

This can tremendously safe your iPhone 12 battery life. The best part is you still hear the notification sound (and the vibration.)

Additionally, you may also choose to turn off app notifications for unnecessary apps like food or grocery delivery ones that spam with half a dozen useless alerts every day!

Enable Optimized Battery Charging

This feature reduces battery aging by learning from your charging routines and waits to juice up the battery after 80% until you need to use it.

For example, if you plug your iPhone 12 into charging overnight every day at your house, it will learn your habit. Now, the phone will normally charge up to 80%. But after that, it will stop charging for the entire night and finish charging past 80% (that is, up to 100%) just before you need to use the iPhone – say early morning.

A notification will display on the screen that tells you when it is scheduled to finish charging. To charge it sooner, touch and hold the notification and tap on ‘Charge Now.’

On iPhone 12, Optimised Battery Charging is turned on by default. To double-check, head over to the Settings app > Battery > Battery Health > make sure Optimised Battery Charging is green.

Buy a Battery Case

If you still can’t manage to make it through the day without recharging your iPhone 12, you may want to purchase a battery case. There are many options available for the iPhone 12.
