Checking battery history
Check how long you've been using HTC Desire 12 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, swipe up and then find and tap Settings.
2. Tap Battery.
3. Tap the chart to vive battery usage over time in History details.
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.
