The Ultimate Guide to Battery Usage Reports on iOS 12


iOS 12, the twelfth major update to Apple’s mobile operating system, introduced several new features, including the highly anticipated battery usage reports. These reports provide detailed information about how apps use your device’s battery, letting you identify battery-hogging apps and make adjustments to optimize your device’s battery life.

In this article, we will dive into the details of battery usage reports on iOS 12, how to generate them, and how to interpret the information they provide.

Detailed Discussion on Battery Usage Reports on iOS 12

What Are Battery Usage Reports?

Battery usage reports provide insights on how your device’s battery is being used by the apps running on it. With these reports, you’ll be able to see which apps are consuming most of your battery and adjust your usage habits accordingly.

To access the battery usage reports, go to Settings > Battery, and you’ll see a list of apps that have used your battery within the last 24 hours or the past seven days. You’ll also see the percentage of battery consumed by each app.

How to Interpret Battery Usage Reports?

When you open the battery usage reports, you’ll see two categories: Battery Usage and Battery Usage by App. The Battery Usage category shows you how long your device has been in use and how long it has been on standby since the last full charge. The Battery Usage by App category displays the total battery consumption for each app on your device, along with the percentage of battery used.

The reports also show how much time an app spent working in the background, which can contribute to battery drain. If an app is using more battery than you expected, you can try minimizing its use or uninstalling it altogether.

How to Optimize Your Battery Life Using the Reports

With the information provided by the battery usage reports, you can take steps to optimize your device’s battery life. Here are a few tips to help you do that:

  • Identify the battery-hogging apps and avoid using them often.
  • Close the apps running in the background, especially those that consume too much battery.
  • Adjust the settings on your phone, such as reducing screen brightness or disabling automatic updates.
  • Use Low Power Mode, which automatically adjusts various settings to help extend your battery life.

Concluding Thoughts on Battery Usage Reports on iOS 12

Battery usage reports on iOS 12 are a useful tool for improving the battery life of your Apple device. By checking these reports, you’ll learn which apps consume most of your battery, and you can reduce your usage to avoid overworking your device.

It’s always essential to prioritize your device’s battery life, and these reports help ensure you do.
