Power Management
On the Battery screen, you can check the estimated battery time remaining, and enable a
power saving mode to extend the battery life of your phone.
Optimize Phone Power Settings
Go to
Settings > Battery (or Optimizer > ) and touch Optimize battery usage.
Your phone will automatically analyze the current power consumption issues, optimize
certain settings, and recommend other setting optimizations.
Enable a Power Saving Mode
Your phone supports two power saving modes:
• Power Saving mode reduces power consumption by limiting background app activity,
visual eects, and sounds.
• Ultra Power Saving mode strictly controls background apps to ensure that your phone can
stay on for as long as possible. In this mode, you will only be able to use selected apps, and
all system switches, except for Wi-Fi and mobile data, will be turned o.
On the Battery screen, select a power saving mode:
