To conserve battery life, disable the phone’s wireless circuitry. Airplane Mode, an option that will turn off all wireless features, is a quick and easy solution in areas with poor reception.
為了省電，可以關閉手機的無線電路。使用飛行模式可以關閉所有無線連接，在網絡不好的地方，這是最便捷、最省事的解決方案。
Alternatively, you can disable (in your phone’s settings) a single wireless feature. For example, if you have terrible wireless carrier coverage in your office, but Wi-Fi is great, disabling cellular connectivity while there will keep the phone from wasting energy trying to get a cellular connection while still letting you connect to the Internet over Wi-Fi.
此外，你也可以嘗試在手機設置里設置單一無線連接方式。比如，如果你的辦公室里無線載波覆蓋不好，但是Wi-Fi很好，那就關閉蜂窩連接，不讓手機費電去連接蜂窩網絡，只用Wi-Fi聯網。
