iPhone battery use

The iOS® battery usage chart may cause you to think the AT&T ActiveArmor app is using more battery than it is. The app works in the background to keep you safe from online threats. Battery usage percentage can vary by customer and changes throughout the day.

How to read the iOS battery usage report:

Go to Settings.
Tap Battery Health & Charging.
Select Last 10 days.
Tap Battery Usage by App, then Show Activity. The Activity column shows the battery percentage by each app for the last 10 days. This number reflects true usage. It’s not unusual for ActiveArmor to be in the 15% to 25% usage range or higher.

Good to know: The total battery usage by app will add up to 100% whether you have one or 10 apps working in background.
