Ways to conserve battery power
Listed below are a few ways you can save your battery power, as well as some facts about battery
usage:
• Adjust wireless settings. If you will not be using your phone’s wireless functionality for a period of
time, you can save power by turning off Wi-Fi or by putting your phone in airplane mode, but
remember you will not be able to receive calls in airplane mode. Read more in “Airplane mode” on
page 27.
• If you are going to be in an area or building that has no cell coverage for a few hours, turn off
your phone or turn on airplane mode and connect to Wi-Fi to conserve power. When you are
out of range of a cell tower your phone will have a shorter standby time because your phone is
searching for a cell tower. This uses more power than if it were already registered with a tower and
simply monitoring.
• If you won’t be using your phone for a period of time, turn it off. Your battery will last two days
if it is turned on and not connected to the charger. Turning off your phone but keeping it connected
to the charger will keep your phone from depleting the battery.
• Turn the Auto-brightness setting on. Auto-brightness is turned on by default. You’ll typically use
more battery power when it’s turned off, unless you manually set the brightness level to stay low.
Read more in “Auto-brightness” on page 31.
• Warm up. The battery capacity will be lower when the temperature is lower. If you think your
phone is too cold, bring it indoors or where the temperature is warmer.
