現今智能手機(ji)的(de)功能越來越強大，但續航依(yi)舊(jiu)是(shi)(shi)痛點，為此不(bu)(bu)少(shao)廠商通過加大電池容量和增(zeng)加快充來彌補。不(bu)(bu)少(shao)用(yong)戶也(ye)希(xi)望通過保養電池來讓手機(ji)用(yong)的(de)時間更長些，所以網上就有了(le)"不(bu)(bu)充滿電就拔掉電源會縮短電池壽命" 的(de)說法，那么，真(zhen)的(de)是(shi)(shi)這樣嗎？

謠言：在充電前得先把電量完全耗盡

智慧手機用(yong)(yong)的(de)是鋰離(li)子(Li-ion)電(dian)(dian)(dian)(dian)池(chi)(chi)，不像傳(chuan)統(tong)鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)或鎳氫電(dian)(dian)(dian)(dian)池(chi)(chi)有電(dian)(dian)(dian)(dian)量記(ji)憶(yi)問題，因此也(ye)不用(yong)(yong)在充(chong)電(dian)(dian)(dian)(dian)前把(ba)電(dian)(dian)(dian)(dian)量耗盡。鋰離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)量計算方式也(ye)和傳(chuan)統(tong)電(dian)(dian)(dian)(dian)池(chi)(chi)不同，使用(yong)(yong)者毋須擔心會發(fa)生過度充(chong)電(dian)(dian)(dian)(dian)的(de)問題。但許多制造(zao)商仍會建議使用(yong)(yong)者，每隔一到三個(ge)月就將電(dian)(dian)(dian)(dian)量耗盡并徹底充(chong)電(dian)(dian)(dian)(dian)一次，藉以“調(diao)校”(Calibrate)電(dian)(dian)(dian)(dian)池(chi)(chi)狀態。

現在(zai)的(de)(de)(de)(de)(de)智能(neng)(neng)手機都用(yong)的(de)(de)(de)(de)(de)是(shi)鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi), 不(bu)像傳(chuan)統的(de)(de)(de)(de)(de)鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)或鎳氫電(dian)(dian)(dian)(dian)池(chi)(chi)有(you)電(dian)(dian)(dian)(dian)量記憶問(wen)題(ti), 所以(yi)在(zai)不(bu)用(yong)耗盡(jin)電(dian)(dian)(dian)(dian)量也能(neng)(neng)無(wu)傷充(chong)電(dian)(dian)(dian)(dian)。而且鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)功率計算也不(bu)同于傳(chuan)統的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi), 用(yong)戶不(bu)必擔心充(chong)電(dian)(dian)(dian)(dian)一(yi)晚上不(bu)拔的(de)(de)(de)(de)(de)問(wen)題(ti)。不(bu)過最好(hao)還(huan)是(shi), 每三個月就用(yong)盡(jin)一(yi)次,然后完全充(chong)電(dian)(dian)(dian)(dian)一(yi)次, 以(yi) "校準" 電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)狀態.

年少的時候，“四驅(qu)車(che)兄(xiong)弟”火極一時，那時候，每(mei)個男孩子都渴(ke)望得(de)到一輛(liang)帥氣的四驅(qu)車(che)。限于當時多數電(dian)動玩具是5號電(dian)池(chi)驅(qu)動，男孩子們為了節約成本，多會(hui)去(qu)購買5號充電(dian)電(dian)池(chi)。相對應的，會(hui)有(you)形色各(ge)異的5號電(dian)池(chi)充電(dian)器(qi).

5號充(chong)電(dian)(dian)電(dian)(dian)池額定電(dian)(dian)壓(ya)為1.2V，當(dang)四驅車跑不動時(shi)，實(shi)際是因電(dian)(dian)解質(zhi)內離子用盡(jin)，電(dian)(dian)壓(ya)僅(jin)能達到1V以下。充(chong)電(dian)(dian)時(shi)，充(chong)電(dian)(dian)器兩端電(dian)(dian)壓(ya)恒定到1.2V，即可因電(dian)(dian)勢差引起電(dian)(dian)池內的(de)離子移動。當(dang)電(dian)(dian)池充(chong)滿(man)，電(dian)(dian)壓(ya)恢復1.2V，電(dian)(dian)池充(chong)滿(man)。

可是，電(dian)池是一個(ge)極其完美(mei)的(de)化學(xue)反應“燒杯”，存(cun)在外(wai)接電(dian)源(yuan)的(de)情況(kuang)下，會(hui)(hui)形(xing)成陰(yin)極-陽極的(de)通路。這時(shi)，雖(sui)然電(dian)壓穩(wen)定，但(dan)正(zheng)負(fu)極仍(reng)然進行著(zhu)復雜(za)的(de)化學(xue)反應。導(dao)致兩個(ge)結(jie)果：電(dian)池溫(wen)度上升、陰(yin)陽極微(wei)觀結(jie)構變化。比(bi)如(ru)，早(zao)期的(de)鎳鎘電(dian)池，過(guo)充化學(xue)反應會(hui)(hui)形(xing)成微(wei)氣泡(pao)，嚴重影響性能。

1.頻繁充電，電池壽命會減少嗎？

不少人認為每塊手機電池都有固定的充電次數，頻繁充電會縮短電池壽命。這種說法其實只針對鎳電池，鋰電池是不一樣的，頻繁充電其實對電池稍有好處。當手機出現電量過低提示，就應及時充電，不要等到手機關機了才充。
 

2.邊玩手機邊充電效率低？

情況(kuang)允許的話，充電(dian)時(shi)關機有利于電(dian)池的保(bao)養。做不(bu)到，也別邊充電(dian)邊玩手機，除(chu)了傷害手機電(dian)池，對人體也有害。畢竟換你餓了正在吃飯，要是(shi)還被(bei)逼著工(gong)作，身體吃不(bu)消(xiao)不(bu)說，咬老板一口的心也會有。對小蘋(pin)果(guo)好一點，畢竟是(shi)身上掉下來(lai)的“腎”吶(na)~~

蘋果(guo)這(zhe)樣的互聯網巨頭公司(si)，可怕就可怕在每一個細節都會(hui)讓(rang)人感覺(jue)到它領先其他手機(ji)廠家(jia)好幾條街：iphone5s之(zhi)后的機(ji)型，會(hui)檢測充(chong)電(dian)(dian)器插上的次數，或者(zhe)是電(dian)(dian)池的電(dian)(dian)壓，如(ru)果(guo)你不拔(ba)掉(diao)充(chong)電(dian)(dian)器，在手機(ji)充(chong)滿電(dian)(dian)之(zhi)后，電(dian)(dian)源(yuan)管(guan)理器就會(hui)自(zi)動(dong)停止充(chong)電(dian)(dian)，開(kai)始放點，放出5%以(yi)后，再(zai)充(chong)電(dian)(dian)，如(ru)此(ci)循(xun)環，直到你拔(ba)掉(diao)為止。

所以親們不用擔心說手機沒充滿電就拔出充電器會對手機電池產生影響這么一說了。
