趴數很重要!專家曝手機「最安全電量」:充太飽也不好

在人手一機的時代,若看到手機電量不到一半,你是否也會莫名地趕
到恐慌,甚至一直充著不拔呢?專家表示電量應該在「最安全電量的
範圍」才可以避免電池出現受損!
物理老師張景超日前YouTube解釋道,傳統充電電池,例如鎳鎘電池
有「記憶效應」特性「比如說我們充電充到80%的時候你把充電線拔
掉,那時候它就會記住,80%就是它充飽電的電量,那你用到剩下20%
的時候你才開始充電,它可能就記得20%是最低電量。」
不過現今手機智慧型手機多為「鋰離子電池」張景超說,此電池沒有
記憶效應的功能,因此提醒網友們,手機千萬別用到沒電才開始充電
!此外鋰離子電池具有「充電週期」一般而言可充電500次。
他近一步解釋「充電週期」例如手機用到剩70%進行充電,充30%直到
100%,下一次用到剩30%進行充電,充70%直到充飽「對我們來說好像
充電2次,但對手機來說它是一個充電週期,因為它第一次30%+第二
次70%=100%」而基本上手機要歷經500次充電週期約需2至3年時間。
但究竟手機剩下多少電量充電最理想呢?張景超建議「手機大概保持
在30~80%之間是最安全的」他說別充太飽的原因在於「過充」會傷
害手機,但也提醒網友們電量別用到低於30%才開始充,因為手機處
於低電量時會出現「過度放電」的問題,也會傷害電池。

物理補習班老師也來解釋充電的概念,滿確定的事情是電量太低會傷電池
這應該是大家的共識了,不過電量太高也會嗎?應該不是這樣吧,我以為都會有過充保護
看來物理補習班老師也未必什麼都懂,謝謝留言提醒,有也不需要幫他們背書
