Using power saver mode
Power saver mode helps to increase battery life. It reduces the usage of phone features that drain
the battery such as the display and data connection.
1. From the Home screen, tap
2. Tap the Power saver On/Off switch to turn power saver mode on or off.
If you want to choose which phone features to conserve power for, tap Power saver.
If power saver mode's Data connection option is selected, HTC One M9+ Supreme Camera
Edition automatically disconnects from the mobile network after 15 minutes when the screen is
off 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.
Keep in mind though that the Sleep mode option for the data connection in Settings > Power,
when enabled, overrides power saver mode.
Extreme power saving mode
In times when you don't need to use much of your phone, turn Extreme power saving mode on to
extend battery life longer. In this mode, standby time can last longer than usual, and you can only
use the most basic functions such as phone calls, text messaging, and email.
1. From the Home screen, tap
2. Tap the Extreme power saving mode On/Off switch to turn extreme power saving mode on
or off.
If you want to set when to automatically switch this mode on, tap Extreme power saving
mode and select a battery level.
