The text provides a step-by-step guide on how to check battery usage on an iPhone, identify high battery-consuming apps, and take action to save battery life. It includes accessing the battery usage information in the Settings app, identifying apps that consume more power, and taking measures such as closing unused apps, turning off background app refresh, reducing screen brightness, and using Low Power Mode to conserve battery.

Checking Battery Usage on iPhone

To check which apps are using the most battery power on your iPhone, follow these steps:

Step 1: Access Battery Usage Information

1. Open the Settings app on your iPhone.

2. Tap on "Battery."

3. You will see a list of apps and their corresponding battery usage percentages over the past 24 hours or 10 days.

- App Name: Percentage Used (Last 24 Hours)
- App Name: Percentage Used (Last 10 Days)

Step 2: Identify High Battery-Consuming Apps

1. Look for apps that have a high percentage in both the last 24 hours and the last 10 days.

2. These apps are likely consuming more battery power than others.

Step 3: Take Action to Save Battery Life

1. Close any apps that you're not currently using by double-tapping the Home button and swiping up on the app previews.

2. Turn off background app refresh for apps that don't need it. Go to Settings > General > Background App Refresh and toggle off any apps you don't need to update in the background.

3. Reduce screen brightness by going to Settings > Display & Brightness > Brightness and adjusting the slider.

4. Use Low Power Mode when your battery gets low. This can be found under Settings > Battery > Low Power Mode.

By following these steps, you can identify which apps are using the most battery power on your iPhone and take action to save battery life.
