Optimizing battery life with power saver mode
Turning power saver mode on helps to increase battery life. It reduces the usage of
phone features that drain the battery such as the CPU and display.
1. Slide the Notifications panel open.
If you want to choose which phone features to conserve power for, tap the
Power saver notification first before you turn power saver mode on.
If Data connection is selected, HTC Butterfly automatically disconnects from the
mobile network after 15 minutes when it's in sleep mode and the data connection is
idle (no download activity, streaming, or data usage). It reconnects and then
disconnects periodically when the data connection is idle to save battery power.
2. Tap the check button next to the Power saver notification to turn power saver
mode on or off.
Getting the battery to last longer
How long the battery can last before it needs recharging depends on how you use
HTC Butterfly. HTC Butterfly power management helps to increase battery life.
