15 tips to preserve iPhone battery life with iOS 16

Some users complain that the life of their phones batteries is affected with each update of the operating system, for rapid battery drain after the update due to syncing and updating behind the scenes, but sometimes problems can last longer, and with the new update system ios 16, “Mac Reminder” has spotted many Tips that preserve the life of phone batteries with the new update

Turn off live activities

With iOS 16.1, Apple has added the Live Activity feature that allows apps to keep a persistent notification on the lock screen or in the iPhone 14 Pro’s dynamic island. Live Activities can be used for things like tracking a sports game, following along with the journey, progressing through a workout, and more, right from the lock screen or the Dynamic Island.

And because every activity on the iPhone drains the battery, including live activities, turning off the persistent notification can put an end to battery drain.

Direct activities can be disabled by following these steps:

Open the Settings app.

Go to Face ID & Passcode.

Enter your passcode to unlock ‌iPhone‌.

Scroll down and toggle on Live Activities.

This will prevent live activities from appearing on the lock screen, but you’ll want to take this a step further. In the individual app sections of the Settings app, you can disable Live Activities on an app-by-app basis, or avoid using Live Activities features within apps.

You can’t disable Dynamic Island completely, but you can swipe left on any running animation to dismiss it.

Delete lock screen widgets

With ‌iOS 16‌, Apple overhauled the lock screen, adding a widget option, where widgets constantly appear on the lock screen and many of them refresh in the background, meaning they’re draining battery power.

For details on adding widgets, removing widgets, and creating lock screens, there is a guide dedicated to iOS 16 lock screen.

Gadgets can also appear on your home screen, a feature prior to iOS 16.

Mac Rumsers recommend not using Home Screen widgets for those concerned about battery life.

Disable touch keyboard feedback

Apple in ‌iOS 16‌ also added a feature that gives you haptic feedback when you use the on-screen keyboard, as it vibrates with every keystroke for a more engaging typing experience, but what you might not know is that it drains battery power, and it can be turned off by following these steps:

Open Settings

Click on Sounds & Haptics

Tap on keyboard notes.

Toggle off Haptic.

iPhone 14 Pro Always Turn Off

The always-on display isn’t an iOS 16‌ feature, but rather an accidental because it was introduced with the “iPhone 14 Pro” and “iPhone 14 Pro Max,” the first two devices that came pre-installed with iOS 16‌.

As the name suggests, the always-on display leaves the time, wallpaper, widgets, and live activities (Apple Watch) visible on the lock screen even when the iPhone is locked, but always on screen still drains the battery faster than no always on screen.

You can turn off the always-on display by following these steps:

Open the Settings app.

Click Display & Brightness

Toggle Always On

Don’t use iCloud Shared Photo Library

Shared Photo Library on iCloud is a feature of iOS 16.1 that lets you use a standard photo library along with five other people, so everyone can upload, edit, and delete photos.

Using your shared photo library on iCloud may sync photos from others to your iPhone at inappropriate times, draining battery life, but you can turn on a setting that only allows syncing over Wi-Fi with these steps:

Open the Settings app.

Scroll down to Pictures.

Click on Cellular Data.

Toggle cellular data on.

Downloads will be restricted to Wi-Fi, so photos shared with you won’t be downloaded to your device when you only have a cellular connection.

Choose non-animated wallpapers

Apple added with ‌iOS 16‌ Live wallpapers that change throughout the day, based on surrounding conditions, which is a feature that sounds nice, but at the same time drains your battery a bit more than its static counterpart, so if that feature doesn’t concern you much, choose wallpapers that won’t update on throughout the day.

Use focus modes

Using Apple’s built-in focus option can reduce the number of notifications you receive during the day, which means less chance for apps to wake up your screen and drain your battery.

Focus modes let you choose which apps and who can send notifications to the user and when, so during work hours he can make sure he only receives work notifications, during personal time he can limit work notifications, and so on.

It will still receive all of its notifications when focus mode ends, but all in one alert instead of a multiple alert. Turning off unwanted notifications from apps is still the best way to save battery life, but the focus allows notifications to be kept while still reducing the number the user receives at any time.

Use the app summary

Ensure that any app that sends unimportant notifications are moved to the app summary, which saves and sends notifications to the user once or twice a day. The app summary isn’t an ‌iOS 16‌ feature, but if you’re not already using it, it’s worth checking it out.

You can switch to the app summary for apps in the notifications section of the Settings app.

Determine when and how apps can access the location

These several tips below are not specific to iOS 16, but it’s always a good idea to check these settings to make sure apps and services aren’t doing things you don’t want them to do.

Restricting which apps can access your location and how often apps access that data can save battery life.

Open the Settings app.

Choose Privacy.

Click Location Services.

Review the list and modify the settings by clicking on the name of each application in the list.

You have four possible options for location settings for each app, although the four options won’t always be available to each app depending on what it’s doing. You can specify: Never, ask next time or when I participate, while using the app, and always.

The app will never block access to your location at all, and unless there is a specific need for an app to know where you are, such as the Maps app, setting location access to Never is the best option.

Ask Next Time will ask the app to ask you in a popup the next time it wants your location, so you can accept it temporarily. With this setting, access to the site is turned off until it is explicitly allowed via the popup.

While using the app Allows the app to detect your location only when the app is open and actively used. If you close the app or switch to another app, access to the site ends.

Always allow the app to access your location at all times, regardless of whether it is open or closed. This will drain the most battery power and should be limited to the apps you need the most.

Lots of apps will ask for location information that you don’t really need to function (for example, a banking app might want to access the location to show nearby ATMs, which are also available by entering a zip code), so clearing unnecessary data makes sure you don’t get access No apps to your location without express permission.

You can also turn off location services together, but it’s not ideal because it can affect important apps like Maps.

Restrict apps that use bluetooth

The iPhone lets you know when apps have requested Bluetooth, and there are quite a few apps that want to access Bluetooth for location tracking, Chromecast devices, or other unhelpful reasons.

Checking apps using Bluetooth is useful to make sure that no hacker app is connecting to Bluetooth sources without your permission and draining your battery. To access Bluetooth settings:

Open the Settings app.

Click on Privacy.

Click on bluetooth.

Apps like Facebook, HBO Max, Hulu, and others don’t need Bluetooth access most of the time, so turn off any app that doesn’t need a Bluetooth connection to work. If a feature in an app stops working, you can turn it back on right away.

Disabling Bluetooth is also an option, but it’s used with AirPods, Apple Watches, and other accessories, so turning it off isn’t possible for most people.

Use Low Power Mode

Using Low Power Mode is an obvious option to conserve battery without having to go through a lot of settings, and you can turn it on from the Control Center, Settings app, or use Siri. Low Power Mode reduces background activity, turns off screen after idle faster, limits display refresh rate, limits email fetching, reduces visual effects, and more.

Low Power Mode can be set to run at a certain battery percentage using shortcuts, which is an easy way to turn it on automatically when you need it.

Use Wi-Fi and Airplane mode

When you can, it’s best to connect to a Wi-Fi network to maximize battery life, which is one of Apple’s battery-saving tips. At home or work, be sure to connect to a Wi-Fi network instead of using a cellular signal.

If you’re in an area with no Wi-Fi and know you have a low cellular signal, turn on Airplane mode or turn off cellular so you don’t drain your battery while trying to connect. This of course only works when you don’t need a cellular connection at the moment, but it can have a huge impact and you probably can’t do much with the low signal anyway.

Manage battery draining apps

Your iPhone tells you which apps are using the most battery power so you can make sure nothing is secretly draining your battery without your knowledge. You can check battery usage stats by opening the Settings app and tapping on the Battery section.

Battery usage charts let you see the battery level for the past 24 hours or the last 10 days, plus you can see which apps have used up the most battery life. If there’s an app you don’t need that drains an excessive amount of battery, delete it. If you need the app, modify how often it is used and what permissions it has, such as location.

Limit background activity

Almost all apps use background refresh to refresh even when they are not open, limited background activity and background refresh is a long time preferred option to reduce battery usage.

You can turn off Background App Refresh all together or choose which apps can refresh in the background.

Open the Settings app.

Select General.

Choose Background App Refresh.

From here, you can tap the Background App Refresh option again to turn off Background App Refresh all at once or choose to only activate it when connected to WiFi, which doesn’t drain your battery as much as downloading via cell phone.

You can also choose to turn on Background App Refresh only for the most frequently used apps by clicking the toggle button next to each app in the list.

Change mail settings

Besides turning off background refresh, changing when and how often the Mail app checks for new emails can save you some battery.

Open the Settings app.

Click on Mail.

Click on Accounts.

Click “Fetch New Data” at the bottom. Fetch mail

From here, you can turn off Push (which lets you know instantly when a new email message is available) and adjust fetch settings on a per-account basis for accounts that don’t support Push (such as Gmail accounts).

Adjusting fetch settings to have longer periods of time before checking for new messages can help save battery life, and turning off fetch together in favor of manual checks that will only download new messages when you open the Mail app.

You can choose the following settings: Automatic, Manual, Hourly, Every 30 minutes, and Every 15 minutes.
