多年來，電池發生了很大的變化。最初手機使用的是鎳鎘電池（ni-cd），接下來是鎳氫電池（ni-mh），然后是(shi)鋰電(dian)(dian)(dian)池(chi)(chi)。鎳鎘(ge)電(dian)(dian)(dian)池(chi)(chi)和鎳氫電(dian)(dian)(dian)池(chi)(chi)擁(yong)有記憶效(xiao)應，因為(wei)在它們(men)完全平衡之后充電(dian)(dian)(dian)，這樣對鎳氫電(dian)(dian)(dian)池(chi)(chi)和鎳鎘(ge)電(dian)(dian)(dian)池(chi)(chi)影(ying)響很小。這些舊電(dian)(dian)(dian)池(chi)(chi)喜歡在初始(shi)充電(dian)(dian)(dian)約12小時（實際(ji)充電(dian)(dian)(dian)5個小時，然后其余為(wei)涓流充電(dian)(dian)(dian)）。

鋰(li)電(dian)(dian)(dian)(dian)(dian)池不像舊電(dian)(dian)(dian)(dian)(dian)池那樣需要充電(dian)(dian)(dian)(dian)(dian)超過(guo)數小時，只需充電(dian)(dian)(dian)(dian)(dian)直到它(ta)(ta)充滿并取(qu)出(chu)它(ta)(ta)。過(guo)度充電(dian)(dian)(dian)(dian)(dian)，你(ni)會損壞(huai)你(ni)的鋰(li)電(dian)(dian)(dian)(dian)(dian)池。鋰(li)離子電(dian)(dian)(dian)(dian)(dian)池和聚合物電(dian)(dian)(dian)(dian)(dian)池完(wan)全不同，因為它(ta)(ta)們對過(guo)充電(dian)(dian)(dian)(dian)(dian)非常敏感，你(ni)只需要給它(ta)(ta)充電(dian)(dian)(dian)(dian)(dian)直到它(ta)(ta)滿了，然后應該盡量避免讓它(ta)(ta)下降到0％，過(guo)度放電(dian)(dian)(dian)(dian)(dian)會降低鋰(li)電(dian)(dian)(dian)(dian)(dian)池的壽命(ming)。

如果0％電(dian)荷(he)為0V，或者(zhe)低到足以(yi)造成損壞電(dian)池，則過放電(dian)事件(jian)將(jiang)(jiang)成立。手機(ji)將(jiang)(jiang)在(zai)此之前關閉(bi)。沒有保護電(dian)路的RC聚合物鋰電(dian)池是另一(yi)(yi)回事，但是像手機(ji)這樣的消費類(lei)設備在(zai)設計時(shi)考慮了電(dian)池規格。一(yi)(yi)些充電(dian)器(qi)，電(dian)池組合將(jiang)(jiang)在(zai)充滿(man)時(shi)關閉(bi)充電(dian)，并且當它們(men)使用(yong)鋰電(dian)池耗盡時(shi)，它將(jiang)(jiang)再次(ci)開始充電(dian)。

當電(dian)(dian)流降至(zhi)(zhi)20mA以(yi)下(xia)時(shi)(shi)，手機中(zhong)的充(chong)電(dian)(dian)電(dian)(dian)路(lu)設置(zhi)為切斷(duan)電(dian)(dian)池供電(dian)(dian)。這將確保電(dian)(dian)池不(bu)會過度充(chong)電(dian)(dian)。同樣(yang)，如(ru)果它(ta)是3.8V電(dian)(dian)池，當電(dian)(dian)壓降至(zhi)(zhi)2.4伏以(yi)下(xia)時(shi)(shi)，手機將斷(duan)開連接，告訴您是時(shi)(shi)候充(chong)電(dian)(dian)了(le)。這種類型的電(dian)(dian)路(lu)已經使用(yong)了(le)至(zhi)(zhi)少10年并且提高(gao)了(le)電(dian)(dian)池的壽命。充(chong)電(dian)(dian)電(dian)(dian)路(lu)中(zhong)包括一(yi)個(ge)定時(shi)(shi)器(qi)，它(ta)定期從(cong)充(chong)電(dian)(dian)中(zhong)釋放電(dian)(dian)池，以(yi)便測量它(ta)1-2秒，然后更(geng)換(huan)它(ta)。

您可以隨(sui)時(shi)為(wei)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)之前局(ju)部放(fang)電(dian)(dian)(dian)(dian)(dian)至(zhi)50％或(huo)更高應該比使其完(wan)全放(fang)電(dian)(dian)(dian)(dian)(dian)更好(hao)并且將(jiang)導致更長的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)壽命。這不(bu)(bu)是必(bi)需(xu)的(de)(de)，但(dan)您可能希望每(mei)隔(ge)幾個月進(jin)(jin)(jin)行一(yi)次完(wan)全放(fang)電(dian)(dian)(dian)(dian)(dian)或(huo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)循(xun)環(huan)來校(xiao)準(zhun)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)量(liang)表。需(xu)要說明的(de)(de)是，物理電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)本(ben)身并不(bu)(bu)需(xu)要一(yi)個完(wan)整的(de)(de)周期（事實上這對他們(men)來說不(bu)(bu)太(tai)理想(xiang)），但(dan)是由于手(shou)(shou)機(ji)和充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器的(de)(de)“智能”組件如(ru)何(he)測量(liang)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)量(liang)（它不(bu)(bu)能直接(jie)測量(liang)，因此需(xu)要根據電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)“完(wan)全充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)”和“完(wan)全放(fang)電(dian)(dian)(dian)(dian)(dian)”進(jin)(jin)(jin)行估算(suan)，如(ru)果(guo)(guo)您只進(jin)(jin)(jin)行部分(fen)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)或(huo)放(fang)電(dian)(dian)(dian)(dian)(dian)循(xun)環(huan)，則該測量(liang)會(hui)隨(sui)著時(shi)間的(de)(de)推(tui)移變(bian)得越來越不(bu)(bu)準(zhun)確。如(ru)果(guo)(guo)你(ni)(ni)沒有校(xiao)準(zhun)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，你(ni)(ni)的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)仍會(hui)持續很長時(shi)間，但(dan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)的(de)(de)程度與它的(de)(de)實際電(dian)(dian)(dian)(dian)(dian)量(liang)有多大不(bu)(bu)同。不(bu)(bu)要擔心(xin)過度充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，因為(wei)手(shou)(shou)機(ji)中的(de)(de)復雜充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)會(hui)在電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)滿(man)時(shi)停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。當(dang)電(dian)(dian)(dian)(dian)(dian)壓降至(zhi)一(yi)定水平(ping)以下時(shi)，手(shou)(shou)機(ji)將(jiang)自(zi)動切(qie)斷，保護電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)不(bu)(bu)會(hui)完(wan)全放(fang)電(dian)(dian)(dian)(dian)(dian)。

總之，根據需要(yao)使(shi)(shi)用(yong)手機(ji)，只需關閉(bi)不必(bi)要(yao)的選項(xiang)，以便在不使(shi)(shi)用(yong)時更快(kuai)地吸取電(dian)池，如藍(lan)牙，WiFi和3G / 4G。這將真正延長您的電(dian)池壽命。當(dang)您看到(dao)電(dian)池性能下(xia)降時，請完全充(chong)電(dian)，然后使(shi)(shi)用(yong)手機(ji)直到(dao)手機(ji)自動關機(ji)。出于同樣的原因，您的第(di)一次使(shi)(shi)用(yong)鋰電(dian)池充(chong)電(dian)應該是滿(man)的。
