5. Turn off wireless when reception is poor.
5. 信號弱的時候關閉無線網絡
You may have noticed that when you’re in a place without good Wi-Fi or cellular coverage, your phone’s battery seems to drain much more quickly. That’s because the phone uses energy searching for a good signal and, if the signal is very weak, trying to get a better connection.
你可能注意到了,在Wi-Fi或蜂窩網絡覆蓋不好的地方,手機電量耗得特別快。這是因為手機會使用電能尋找耗得信號,如果信號特別弱,還要試著更好地去連接。
