在使用手機時，值得大家應注意的是鋰電池，電(dian)(dian)(dian)池放(fang)(fang)置一段時(shi)間(jian)后則進入休眠狀態，此時(shi)容量低于正常(chang)值，使用時(shi)間(jian)亦隨之縮短。但鋰電(dian)(dian)(dian)池很容易(yi)激活，只要經過(guo)3―5次正常(chang)的(de)充(chong)放(fang)(fang)電(dian)(dian)(dian)循環就可激活電(dian)(dian)(dian)池，恢復(fu)正常(chang)容量。由(you)于鋰電(dian)(dian)(dian)池本身的(de)特(te)性，決定(ding)了它(ta)幾乎沒有(you)記憶效應(ying)。因此用戶手機中的(de)新(xin)鋰電(dian)(dian)(dian)池在激活過(guo)程中，是(shi)不需要特(te)別的(de)方法和設備(bei)的(de)。不僅(jin)理論(lun)上是(shi)如(ru)此，從我自己(ji)的(de)實踐(jian)來看，從一開始就采(cai)用標(biao)準(zhun)方法充(chong)電(dian)(dian)(dian)這種(zhong)“自然激活”方式是(shi)最(zui)好的(de)。

     對于鋰電池的“激活”問題，眾多的說法是：充電時間一定要超過12小時，反復做三次，以便激活電池。這種“前三次充電要充12小時以上”的說法，明顯是從鎳電池（如鎳鎘和鎳氫）延續下來的說法。所以這種說法，可以說一開始就是誤傳。鋰電池和鎳電池的充放電特性有非常大的區別，而且可以非常明確的告訴大家，我所查閱過的所有嚴肅的正式技術資料都強調過充和過放電會對鋰電池、特別是液體鋰離子電池造成巨大的(de)傷害。因而充(chong)(chong)電(dian)(dian)最好按照(zhao)標(biao)準時間和標(biao)準方(fang)法(fa)(fa)充(chong)(chong)電(dian)(dian)，特別是(shi)不要進行超過12個小時的(de)超長充(chong)(chong)電(dian)(dian)。通常(chang)，手(shou)機(ji)說(shuo)明書(shu)上介紹的(de)充(chong)(chong)電(dian)(dian)方(fang)法(fa)(fa)，就是(shi)適合該手(shou)機(ji)的(de)標(biao)準充(chong)(chong)電(dian)(dian)方(fang)法(fa)(fa)。

    此(ci)外，鋰電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)手(shou)機或充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)滿后都會自動停充(chong)(chong)(chong)，并不存在(zai)(zai)(zai)鎳電(dian)(dian)(dian)(dian)(dian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)所謂的(de)持續(xu)10幾小時(shi)的(de)“涓流”充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。也(ye)就是(shi)說，如果你的(de)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)在(zai)(zai)(zai)充(chong)(chong)(chong)滿后，放在(zai)(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)上也(ye)是(shi)白(bai)充(chong)(chong)(chong)。而我們(men)誰都無法保(bao)證電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)保(bao)護電(dian)(dian)(dian)(dian)(dian)路的(de)特性永不變(bian)化和質(zhi)量的(de)萬無一(yi)失，所以你的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)將長(chang)期(qi)處在(zai)(zai)(zai)危險的(de)邊緣(yuan)徘徊。這也(ye)是(shi)我們(men)反對(dui)長(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)另一(yi)個理(li)由。

1、此外在對某(mou)些手機上，充(chong)電(dian)(dian)(dian)(dian)(dian)超過一定(ding)的(de)(de)時(shi)(shi)間(jian)后(hou)，如果不(bu)(bu)去取下充(chong)電(dian)(dian)(dian)(dian)(dian)器，這(zhe)時(shi)(shi)系統不(bu)(bu)僅不(bu)(bu)停(ting)止充(chong)電(dian)(dian)(dian)(dian)(dian)，還將(jiang)開始放電(dian)(dian)(dian)(dian)(dian)-充(chong)電(dian)(dian)(dian)(dian)(dian)循環。也(ye)許這(zhe)種做法的(de)(de)廠(chang)商(shang)自(zi)有其目的(de)(de)，但顯然(ran)對電(dian)(dian)(dian)(dian)(dian)池(chi)和(he)手機/充(chong)電(dian)(dian)(dian)(dian)(dian)器的(de)(de)壽(shou)命而言是(shi)不(bu)(bu)利的(de)(de)。同時(shi)(shi)，長(chang)充(chong)電(dian)(dian)(dian)(dian)(dian)需要很長(chang)的(de)(de)時(shi)(shi)間(jian)，往(wang)往(wang)需要在夜(ye)間(jian)進行(xing)，而以(yi)我國(guo)電(dian)(dian)(dian)(dian)(dian)網的(de)(de)情況看(kan)，許多(duo)地方夜(ye)間(jian)的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)都(dou)比(bi)較高(gao)，而且(qie)波(bo)動較大。前面已經說過，鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)很嬌(jiao)貴(gui)的(de)(de)，它比(bi)鎳電(dian)(dian)(dian)(dian)(dian)在充(chong)放電(dian)(dian)(dian)(dian)(dian)方面耐波(bo)動的(de)(de)能(neng)力差(cha)得多(duo)，于是(shi)這(zhe)又(you)帶來附(fu)加的(de)(de)危(wei)險。 此外，不(bu)(bu)可忽視的(de)(de)另外一個方面就是(shi)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)同樣也(ye)不(bu)(bu)適(shi)合過放電(dian)(dian)(dian)(dian)(dian)，過放電(dian)(dian)(dian)(dian)(dian)對鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)同樣也(ye)很不(bu)(bu)利。

2、正常使用(yong)中應該何(he)時開(kai)始充電

在我(wo)們的(de)論(lun)壇上，經常可(ke)(ke)以見(jian)到(dao)這種說法，因為充放電(dian)的(de)次數(shu)是有限的(de)，所以應該將手機電(dian)池的(de)電(dian)盡可(ke)(ke)能用光再充電(dian)。但是我(wo)找到(dao)一個(ge)關于鋰離子電(dian)池充放電(dian)循環的(de)實驗表，關于循環壽命的(de)數(shu)據列出如(ru)下：

循環壽命 (10%DOD):>1000次

循環壽命 (100%DOD):>200次

其(qi)中DOD是(shi)放(fang)(fang)(fang)電(dian)(dian)深(shen)度(du)(du)的(de)英文縮寫。從(cong)表中可(ke)見，可(ke)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)次(ci)數和放(fang)(fang)(fang)電(dian)(dian)深(shen)度(du)(du)有(you)(you)關，10%DOD時(shi)(shi)(shi)的(de)循(xun)環(huan)壽命(ming)(ming)要比(bi)100%DOD的(de)要長很多。當(dang)然如果(guo)折合到(dao)(dao)實(shi)(shi)際(ji)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)的(de)相對總(zong)容量(liang)(liang)：10%*1000=100，100%*200=200，后(hou)者(zhe)的(de)完(wan)全(quan)充(chong)(chong)(chong)(chong)(chong)放(fang)(fang)(fang)電(dian)(dian)還是(shi)要比(bi)較好一些，但(dan)前面網友的(de)那個(ge)說法(fa)要做一些修正：在正常情況下，你(ni)應(ying)該有(you)(you)保留地(di)按照電(dian)(dian)池(chi)(chi)剩余(yu)電(dian)(dian)量(liang)(liang)用(yong)(yong)完(wan)再充(chong)(chong)(chong)(chong)(chong)的(de)原則充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)，但(dan)假(jia)如你(ni)的(de)電(dian)(dian)池(chi)(chi)在你(ni)預(yu)計第(di)2天(tian)不(bu)(bu)可(ke)能堅持整個(ge)白天(tian)的(de)時(shi)(shi)(shi)候，就(jiu)應(ying)該及(ji)時(shi)(shi)(shi)開(kai)始(shi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)，當(dang)然你(ni)如果(guo)愿意背(bei)著充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)器到(dao)(dao)辦公室又當(dang)別論。而(er)你(ni)需要充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)以(yi)應(ying)付預(yu)計即將到(dao)(dao)來的(de)會(hui)(hui)導(dao)致通訊繁忙的(de)重要事件的(de)時(shi)(shi)(shi)候，即使在電(dian)(dian)池(chi)(chi)尚(shang)有(you)(you)很多余(yu)電(dian)(dian)時(shi)(shi)(shi)，那么(me)你(ni)也只管提(ti)前充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)，因(yin)為(wei)你(ni)并沒有(you)(you)真正損失(shi)“1”次(ci)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)循(xun)環(huan)壽命(ming)(ming)，也就(jiu)是(shi)“0.x”次(ci)而(er)已，而(er)且往往這個(ge)x會(hui)(hui)很小。 電(dian)(dian)池(chi)(chi)剩余(yu)電(dian)(dian)量(liang)(liang)用(yong)(yong)完(wan)再充(chong)(chong)(chong)(chong)(chong)的(de)原則并不(bu)(bu)是(shi)要你(ni)走向極端。和長充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)一樣流傳甚廣的(de)一個(ge)說法(fa)，就(jiu)是(shi)“盡量(liang)(liang)把手(shou)機(ji)(ji)電(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)量(liang)(liang)用(yong)(yong)完(wan)，最好用(yong)(yong)到(dao)(dao)自(zi)動關機(ji)(ji)”。這種做法(fa)其(qi)實(shi)(shi)只是(shi)鎳(nie)電(dian)(dian)池(chi)(chi)上的(de)做法(fa)，目的(de)是(shi)避(bi)免記憶效應(ying)發生，不(bu)(bu)幸的(de)是(shi)它也在鋰(li)電(dian)(dian)池(chi)(chi)上流傳之今。曾經有(you)(you)人(ren)因(yin)為(wei)手(shou)機(ji)(ji)電(dian)(dian)池(chi)(chi)電(dian)(dian)量(liang)(liang)過(guo)低(di)的(de)警告出現后(hou)，仍然不(bu)(bu)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)繼(ji)續使用(yong)(yong)一直用(yong)(yong)到(dao)(dao)自(zi)動關機(ji)(ji)的(de)例子。結果(guo)這個(ge)例子中的(de)手(shou)機(ji)(ji)在后(hou)來的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)及(ji)開(kai)機(ji)(ji)中均無(wu)反應(ying)，不(bu)(bu)得不(bu)(bu)送客服檢修。這其(qi)實(shi)(shi)就(jiu)是(shi)由于(yu)電(dian)(dian)池(chi)(chi)因(yin)過(guo)度(du)(du)放(fang)(fang)(fang)電(dian)(dian)而(er)導(dao)致電(dian)(dian)壓過(guo)低(di)，以(yi)至于(yu)不(bu)(bu)具(ju)備正常的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)和開(kai)機(ji)(ji)條件造成的(de)。

3、對鋰電池手機的正確做法

歸結起來，我對鋰電池手機在使用中的(de)充放電問題最重要的(de)提示是：

1、按(an)照標準的時(shi)間和程序(xu)充(chong)電(dian)，即使(shi)是前三次(ci)也要如此(ci)進(jin)行(xing)；

2、當(dang)出現手機電(dian)量過低提示時(shi)，應(ying)該盡量及時(shi)開始充電(dian)；

3、鋰(li)電池的(de)激(ji)活(huo)(huo)并不需(xu)要特(te)別的(de)方(fang)法，在(zai)手機正常使用中鋰(li)電池會自然激(ji)活(huo)(huo)。如果(guo)你執意要用流傳的(de)“前三次12小時長充電激(ji)活(huo)(huo)”方(fang)法，實(shi)際上也不會有效果(guo)。

因此，所有追求12小時(shi)超長充(chong)電和把(ba)鋰電池手(shou)機用(yong)到自(zi)動關機的做法，都是(shi)錯誤的。如果你(ni)(ni)以前(qian)是(shi)按照錯誤的說(shuo)法做的，請你(ni)(ni)及(ji)時(shi)改正，也許為時(shi)還不晚(wan)。

    當然(ran)，在手機及充電(dian)器自身保護和控(kong)制電(dian)路質量良好(hao)的(de)(de)情(qing)況下(xia)(xia)，對鋰電(dian)池的(de)(de)保護還是有相當保證(zheng)的(de)(de)。所以對充電(dian)規則(ze)的(de)(de)理解才(cai)是重點，在某些(xie)情(qing)況下(xia)(xia)也是可(ke)以做出某種讓步(bu)的(de)(de)。比如你(ni)發現(xian)手機在你(ni)夜晚(wan)睡覺前必(bi)須充電(dian)的(de)(de)話，你(ni)也可(ke)以在睡前開(kai)始充電(dian)。問題的(de)(de)關鍵(jian)在于(yu)，你(ni)應(ying)該知道(dao)正確的(de)(de)做法是什么，并且不(bu)要刻意按照錯誤的(de)(de)說法去做。

希望(wang)大家努力掌(zhang)握關(guan)于鋰電(dian)池(chi)的(de)知識和學會正(zheng)確使用鋰電(dian)池(chi)的(de)科學方法，早日在鋰電(dian)池(chi)的(de)手機上與流(liu)傳已久的(de)錯誤說法和做(zuo)法告別。
