現今(jin)智能手機(ji)的(de)功能越來越強(qiang)大，但續航依舊(jiu)是(shi)痛點，為此不少(shao)廠商通過加大電(dian)池容量和增加快充來彌補。不少(shao)用戶也希(xi)望通過保養(yang)電(dian)池來讓手機(ji)用的(de)時間(jian)更長些，所以網上就(jiu)有了"不充滿電(dian)就(jiu)拔掉(diao)電(dian)源(yuan)會縮短(duan)電(dian)池壽命" 的(de)說法，那(nei)么，真的(de)是(shi)這(zhe)樣嗎？

謠言：在充電前得先把電量完全耗盡

智(zhi)慧手機用(yong)的(de)(de)是鋰離子(Li-ion)電(dian)(dian)(dian)(dian)池(chi)(chi)，不(bu)像傳(chuan)統鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)或鎳氫電(dian)(dian)(dian)(dian)池(chi)(chi)有電(dian)(dian)(dian)(dian)量記憶問(wen)題(ti)，因此也不(bu)用(yong)在充(chong)電(dian)(dian)(dian)(dian)前把電(dian)(dian)(dian)(dian)量耗盡(jin)。鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)量計算方式也和傳(chuan)統電(dian)(dian)(dian)(dian)池(chi)(chi)不(bu)同，使用(yong)者毋須擔心會發生過(guo)度充(chong)電(dian)(dian)(dian)(dian)的(de)(de)問(wen)題(ti)。但許多制造商仍會建議使用(yong)者，每隔(ge)一(yi)到(dao)三(san)個(ge)月就將電(dian)(dian)(dian)(dian)量耗盡(jin)并徹底(di)充(chong)電(dian)(dian)(dian)(dian)一(yi)次，藉以“調校”(Calibrate)電(dian)(dian)(dian)(dian)池(chi)(chi)狀態。

現在(zai)(zai)的(de)(de)(de)智(zhi)能手機都(dou)用的(de)(de)(de)是(shi)鋰(li)離(li)子電(dian)(dian)池(chi)(chi), 不(bu)(bu)像傳統的(de)(de)(de)鎳鎘電(dian)(dian)池(chi)(chi)或鎳氫電(dian)(dian)池(chi)(chi)有電(dian)(dian)量記憶問(wen)題, 所以在(zai)(zai)不(bu)(bu)用耗盡(jin)電(dian)(dian)量也能無(wu)傷充電(dian)(dian)。而且鋰(li)離(li)子電(dian)(dian)池(chi)(chi)的(de)(de)(de)功(gong)率計(ji)算也不(bu)(bu)同于傳統的(de)(de)(de)電(dian)(dian)池(chi)(chi), 用戶(hu)不(bu)(bu)必擔(dan)心充電(dian)(dian)一晚上(shang)不(bu)(bu)拔的(de)(de)(de)問(wen)題。不(bu)(bu)過最好還是(shi), 每三個月就用盡(jin)一次,然后完(wan)全充電(dian)(dian)一次, 以 "校準" 電(dian)(dian)池(chi)(chi)的(de)(de)(de)狀態.

年少的時候，“四驅(qu)車兄弟(di)”火(huo)極一(yi)時，那時候，每個男(nan)孩子都渴望得到一(yi)輛(liang)帥(shuai)氣的四驅(qu)車。限(xian)于當時多數電(dian)動玩具(ju)是5號電(dian)池驅(qu)動，男(nan)孩子們為(wei)了(le)節約成本，多會去(qu)購買5號充(chong)(chong)電(dian)電(dian)池。相對(dui)應的，會有形色各異(yi)的5號電(dian)池充(chong)(chong)電(dian)器(qi).

5號充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池額定電(dian)(dian)(dian)壓為1.2V，當四驅車跑不動時，實(shi)際是因(yin)(yin)電(dian)(dian)(dian)解質內離子(zi)用盡，電(dian)(dian)(dian)壓僅能達到(dao)1V以下。充(chong)電(dian)(dian)(dian)時，充(chong)電(dian)(dian)(dian)器(qi)兩端(duan)電(dian)(dian)(dian)壓恒(heng)定到(dao)1.2V，即可(ke)因(yin)(yin)電(dian)(dian)(dian)勢差引起(qi)電(dian)(dian)(dian)池內的離子(zi)移動。當電(dian)(dian)(dian)池充(chong)滿，電(dian)(dian)(dian)壓恢復1.2V，電(dian)(dian)(dian)池充(chong)滿。

可是，電(dian)(dian)池(chi)是一個極其完(wan)美的化學(xue)反應“燒杯”，存在(zai)外接電(dian)(dian)源的情(qing)況下(xia)，會形成陰極-陽(yang)極的通路。這(zhe)時，雖(sui)然電(dian)(dian)壓穩定，但正負極仍然進行著(zhu)復(fu)雜的化學(xue)反應。導致兩(liang)個結(jie)果(guo)：電(dian)(dian)池(chi)溫度(du)上升、陰陽(yang)極微觀結(jie)構變化。比如，早期的鎳鎘電(dian)(dian)池(chi)，過充化學(xue)反應會形成微氣(qi)泡，嚴重影響(xiang)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(de)話，充電時關機(ji)有利于(yu)電池的(de)保養(yang)。做不到(dao)，也(ye)別(bie)邊(bian)充電邊(bian)玩手(shou)機(ji)，除了(le)傷害手(shou)機(ji)電池，對人體也(ye)有害。畢(bi)竟(jing)換你餓了(le)正在吃(chi)飯(fan)，要是(shi)還被逼(bi)著工作，身(shen)體吃(chi)不消不說，咬老板一(yi)口的(de)心(xin)也(ye)會有。對小蘋果好一(yi)點，畢(bi)竟(jing)是(shi)身(shen)上掉下來的(de)“腎”吶(na)~~

蘋(pin)果這(zhe)樣的(de)互聯網(wang)巨頭公(gong)司(si)，可(ke)怕(pa)就(jiu)可(ke)怕(pa)在(zai)每一個細節都會(hui)讓人感覺(jue)到它領先其他手機(ji)廠家好幾條(tiao)街：iphone5s之后(hou)(hou)的(de)機(ji)型，會(hui)檢測(ce)充(chong)(chong)電(dian)(dian)(dian)器插上的(de)次數，或者是電(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)壓，如果你不拔(ba)掉(diao)充(chong)(chong)電(dian)(dian)(dian)器，在(zai)手機(ji)充(chong)(chong)滿電(dian)(dian)(dian)之后(hou)(hou)，電(dian)(dian)(dian)源管理器就(jiu)會(hui)自動停止(zhi)充(chong)(chong)電(dian)(dian)(dian)，開始放點，放出5%以后(hou)(hou)，再充(chong)(chong)電(dian)(dian)(dian)，如此(ci)循環，直到你拔(ba)掉(diao)為(wei)止(zhi)。

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。
