Sharp OMPB10ZU manual Headset Jack, Ways to conserve battery power

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 31.

•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 to save the most power. You can leave your phone turned off and not connected to the battery charger for approximately two days before the battery will completely discharge.

•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 37.

•Warm up. The battery capacity will be lower when the temperature is lower. If you think your phone is suffering from the cold, bring it indoors or where the temperature is warmer.

HEADSET JACK

Your phone is designed to use a stereo headset. To use a headset, insert the headset lead into the headset jack. Be sure to press the headset lead in firmly to secure the connection.

Read about how to use the headset control button(s) in “Can I control a call with a headset?” on page 53 and “Listen to media with headset, headphones, or Bluetooth device” on page 112.

Note: In order to listen to the FM radio in Music & More, you must insert a wired headset or headphone (the wire works as the antenna).
