View Battery Usage information

With iOS, you can easily manage your device’s battery life, because you can see the proportion of your battery used by each app (unless the device is charging). To view your usage, go to Settings > Battery.

Here are the messages you may see listed below the apps you’ve been using:

Background Activity. This indicates that the battery was used by the app while it was in the background — that is, while you were using another app.

• To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh and select Wi-Fi, Wi-Fi & Cellular Data, or Off to turn off Background App Refresh entirely.

• If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval. Go to Settings > Accounts & Passwords > Fetch New Data.

Location and Background Location. This indicates that the app is using location services.

• You can optimize your battery life by turning off Location Services for the app. Turn off in Settings > Privacy > Location Services.

• In Location Services, you can see each app listed with its permission setting. Apps that recently used location services have an indicator next to the on/off switch.

Carefully 🙂

Slowly swipe upwards from bottom left until the app is shown in the screen in reduced format

then click on any one of the apps until the red DELETE shows in upper left of the app window.

Click DELETE

It took me a while to get the hang of it. Pic below shows three apps open

Pic below shows delete button afterwards

You then just start deleting the ones you want.

To open the App Switcher, swipe up from the bottom of the screen and hold for a second. Then scroll left or right to find the app to be closed. Then press and hold the app until a little red circle appears. Press the circle to close it.

Switch apps on your iPhone, iPad, or iPod touch

Good luck.

Although you've been given instructions on how to do this, note that it is rarely required (i.e. only when an app acts up). There is zero advantage to closing apps in terms of battery consumption or memory.
