Pay attention to available iOS/iPadOS software updates and install them as they become available, because they typically include bug fixes, and if there’s a known bug causing battery issues it will certainly be resolved in such an update.

You can look for any new iOS/iPadOS updates by going to Settings -> General -> Software Update, and tap on “Download and Install” if any new software is available.

Updating apps will ensure the compatibility with the latest iOS/iPadOS versions, and that may include resolving battery issues.

Open the App Store, then tap your Apple ID profile icon at the top-right corner of the screen. Scroll down and choose “Update All” to install available app updates.

---

Find which apps are using the battery by going to Settings -> Battery. You may notice an outlier or two, typically streaming video or games, and other than updating those apps you might consider quitting them if you’re not using them.

You can also check device battery health, if it’s lower than 80% it may be worthwhile to replace the battery of the devices– though this shouldn’t have anything to do with the iOS 15 update.

Spotify is currently known to drain the battery on iPhone with iOS 15 at a rather significant pace for some users, particularly notable when the app is in the background. There are a few workarounds to this, but a fix from Spotify is in the works.

Deleting and reinstalling Spotify from iPhone has resolved the problem for some users. If Spotify is draining the battery while running in the background, disabling Background App Refresh for Spotify (or in general, more on that in a moment) can make a notable difference. If Spotify is running in the foreground, stopping Spotify from playing music videos may help to reduce the battery usage.

Disabling background app refresh is a common trick to extend battery life, and most users won’t notice the difference in terms of how their iPhone or iPad operates. Go Settings > General -> Background App Refresh and toggle this OFF

---

Turning down the brightness of your display can help to prolong the battery life of the iPhone since doing so causes the device to use less energy. Adjusting screen brightness is easy via Settings > Display & Brightness and using the slider.

Please note that the tips under this section are to highlight areas where you could disable things that are not applicable to you so you can extend battery life. We are not recommending or advising you to disable features just for battery life, as then there would be no point in using smartphones like the iPhone.

Location Services

Disable the unwanted location services for Apps. Location Services are great and necessary for Maps apps, and things like ride hailing, and food delivery apps, but they’re not necessary for many other apps. Location usage drains the battery, so disabling unwanted location usage can help.

Go to Settings -> Privacy -> Location Services, and choose the apps to disable location usage for. Set Location Access to “Never” or “Ask Next Time”.

Bluetooth

If you hardly use Bluetooth then turn it off (Settings -> General -> Bluetooth)

Widgets

The Widgets in the Lock Screen and Notification Center (when you swipe left) include widgets for Stock and Weather and any other third-party Notification Center widget you may have added. You should review the list and remove the widgets that you don’t want to ensure they don’t consume battery life unnecessarily as some of them could be using Location services.

Turn off Dynamic Wallpapers

Dynamic wallpapers bring subtle animations to the home and the lock screen. Unfortunately, the animations take up CPU cycles and consume more battery. So if you have set a dynamic wallpaper, and you’re having battery issues, go to Settings > Wallpaper > Choose Wallpaper where you can go to either Stills or set an image from your photo library as your wallpaper. iPhone 6s or later also allows you to set Live Photos as wallpapers, but it should have an impact on battery life as they come to life only when you use 3D Touch to firmly press on the wallpaper.

Disable Motion effects, parallax

iOS comes with a number of animations and physics-based effects to the interface to help users understand the layered elements in the UI. Some of these effects even access gyroscopic data, which contributes further to the battery drain. You can disable these motion effects by going to Settings > General > Accessibility > Reduce Motion and turn on the switch. However, please note that enabling Reduce Motion will disable the effects in the Messages app.
