5. TUNE PERFORMANCE
5.1. Optimise Battery Life
You can extend your battery's life between charges by turning off features that you don't
need. You can also monitor how apps and system resources consume battery power.
To adjust the settings described here, first touch the Settings icon on a Home or All
Apps screen.
Extend the life of your battery
If you aren't using Wi-Fi, Bluetooth, or GPS, use the Settings app to turn them off.
The GPS setting is located in Settings > Personal > Location services.
Don't leave the Maps or Navigation apps open on the screen when you're not
using them. They use GPS and therefore more power when they are running.
Turn down screen brightness and set a shorter Sleep timeout by choosing
Settings > Device > Display.
If you don't need it, turn off automatic syncing for all apps by selecting Settings >
Personal > Accounts & sync. Note that this means you need to sync manually to
collect messages, email, and other recent information, and won't receive
notifications when updates occur.
If you know you won't be near a mobile or Wi-Fi network for a while, switch to
Airplane mode by Pressing and holding the power ON/OFF option until the
Phone options appears. Then touch Airplane Mode.
Check battery level and usage details
Go to Settings > Device > Battery.
The list displayed on the screen shows you the breakdown of battery usage for
individual apps and services. Touch a graph for more details. The details screen for
some apps includes buttons that allow you to adjust settings affecting power
usage, or stop the app completely.
Battery status (charging, discharging) and level (as a percentage of fully charged)
are displayed at the top of the screen. The discharge graph shows battery level
over time since you last charged the device.
