Checking battery usage
See how the system and apps are using the battery and how much power is being used.

Another way to check the battery usage per app is to go to Settings > Apps. Tap the app you want to
check, and then tap Battery.
If the Battery option on the App info screen is grayed out, it means the app is currently not using

Checking battery history
Check how long you've been using HTC One A9 since the last charge. You can also see a chart that
shows how long the screen has been on, and how long you've been using connections like the mobile
network or Wi-Fi.
1. From the Home screen, tap
2. Tap History to view battery usage over time.
Battery optimization for apps
When you have connections such as Wi-Fi on while the phone is in sleep mode, some apps may still
continue to use the battery. Starting from Android 6.0, battery optimization is enabled for all apps
by default which helps prolong battery standby time when you're not using the phone.
The phone needs to be sitting idle for an extended period of time before battery optimization takes
effect.
