Battery usage types

Hello. I am wondering about specific battery usage types in the battery usage by app section. I have an app that has “notifications” listed underneath the name of the app. What does this mean? Does this mean the majority of the use of the app was from notifications coming through whilst the app was closed? I have looked for other battery usage types but haven’t found an answer for the “notifications” one. Thanks!

That is correct. When a notification arrives for an app the app is launched to process the notification, and if the phone is locked and has a local Wi-Fi network then Wi-Fi is enabled for 30 seconds to allow the app to download the notification. This will happen whether or not you close the app in the app switcher (which you should never do, BTW, unless the app is not working correctly).

Yes, sort of. When the server that supports an app has an update for the app it “pushes” an update notification to the app via the cellular network. The app then wakes up and says “tell me about it”, so it is actually pulling the information from the server.

Try to monitor Battery usage by iPhone Activity as shown below

What is shown under battery usage? Checking that would give you an indication of the usage behavior.

1. Background Activity
2. Notifications
3. Connected to Charger

To prolong the life of your iPhone battery, you can follow these tips and best practices:

1. Optimize Battery Charging: Enable the "Optimized Battery Charging" feature on your iPhone. It helps reduce the wear on the battery by slowing down the battery aging process. You can find this option in Settings > Battery > Battery Health. About Optimized Battery Charging on your iPhone - Apple Support (IN)
2. Avoid Extreme Temperatures: Extreme temperatures, both hot and cold, can negatively impact your battery life. Avoid exposing your iPhone to excessive heat or cold, such as leaving it in direct sunlight or in a freezing car.If your iPhone or iPad gets too hot or too cold – Apple Support (UK)
3. Use Original Chargers and Cables: Always use Apple's original chargers and cables or certified third-party accessories. Low-quality chargers or cables can damage the battery and reduce its lifespan. Identify counterfeit or uncertified Lightning connector accessories - Apple Support (IN)
4. Avoid Draining the Battery to Zero: Charge it whenever the charge becomes lower than 20%. The rest is up to you when to charge. how long to charge, how often to charge, which adapter to use starting from 5W to 140W USB-C Power Adapter etc.
5. Optimize Display Settings: Adjust your display settings to optimize battery life. Lower the screen brightness, enable auto-brightness, and use shorter screen timeout durations. Adjust the display and text size on iPhone - Apple Support (IN)
6. Minimize Background App Refresh: Limit the number of apps allowed to refresh in the background. Go to Settings > General > Background App Refresh and disable it for apps that don't require real-time updates. Switch apps on your iPhone, iPad, or iPod touch - Apple Support (IN)
7. Disable Push Email: Push email notifications can drain your battery quickly. Instead, set your email accounts to fetch data manually or at longer intervals. You can change this setting in Settings > Mail > Accounts > Fetch New Data.

If an app supports notifications the app’s server will send notifications to the app. If you don’t have notifications enabled they won’t appear on the notifications screen, but the app will still receive them. As one example, a weather app is notified any time there is a new weather report so it can update its content. Or a communications app will be notified that a new message has been sent to you, so the app can save the message.
