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.

If you expect a Theft Alert email but don’t get one:

Check your spam or junk folders
Make sure your email displays images
Open the email on a desktop browser

FYI: Alerts may not capture a photo if the lighting is poor, or the phone shuts down too quickly. You’ll get another alert if another trigger is detected.

Suspend wireless service

If you think your phone has been stolen, you can suspend your service and block your device so that you don't incur any unwanted charges.

To prevent unauthorized account changes, turn on wireless account lock.
