User's Guide
● To specify battery optimization for any apps, go to Settings / Battery, then tap (in the
upper right corner) / Battery usage. Tap on any app in the list to view options. Under the
MANAGE BATTERY USAGE heading, you can view or select Background restriction and
Battery optimization.
○ Background restriction - to save battery, tap this and then choose RESTRICT, which
will stop the app from using battery in the background. NOTE: this may cause apps
to work improperly and cause delayed notifications.
○ Battery optimization - most apps will have the Optimizing battery use setting
enabled by default. Tap this option to view apps that are not optimized. Select All
apps from the drop down next to NOT OPTIMIZED to view all apps. Select an app
from the list to turn Battery Optimization on or off. Turning off is not recommended,
as it may drain the battery more quickly as the app will no longer be restricted from
using background battery.
● Stretch a low battery’s power. To help a dying battery last until you can plug in your
device, first turn on Battery saver mode. Often, battery saver is all you’ll need for a low
battery’s power to last until you can get to a charger. Stretch your remaining battery power
with temporary changes to your settings/usage.
Tip: You'll want to turn your features back on when you recharge.
○ Avoid high-drain activities (for example, heavy screen use, heavy data processing).
○ Turn off the wireless radios when not using them to limit connectivity (for example,
turn on Airplane mode, turn off Bluetooth). See Using wireless networks.
○ Limit location data (for example, turn on GPS battery saving mode, turn off
Location services).
○ Limit automatic syncing (for example, turn off auto-sync for your Google account,
turn off auto-sync for certain Google apps).
● Unplug USB devices. Many USB devices use power just by being connected. If you use a
USB flash drive, unplug it when you are not using it.
● Turn off EMPOWER modules if you will not be using them for a prolonged period; see
Disabling and enabling modules in the EMPOWER Hub.
● Decrease the display brightness to the lowest comfortable level. See Display settings for
more information.
● Turn off screen rotation. See Display settings for more information.
● If you don't work in low light settings, disable the keypad backlight. Navigate to Settings >
System > Languages & input > Physical keyboard > Built-in Keyboard. Tap the slider next
to Enable to disable the keyboard backlight.
○ You may also adjust the brightness of the keyboard backlight in the same section by
moving the slider left or right under the title Backlight brightness.
● Turn off the handheld when you are not using it. See Turning off the device.
