現今智能手(shou)機的(de)功能越(yue)來(lai)越(yue)強大，但續航依舊是痛點(dian)，為此不少(shao)廠(chang)商(shang)通(tong)過加大電(dian)池(chi)(chi)容量和增加快充來(lai)彌補。不少(shao)用(yong)戶也希望通(tong)過保養電(dian)池(chi)(chi)來(lai)讓手(shou)機用(yong)的(de)時間更長些，所以網上就有了(le)"不充滿(man)電(dian)就拔掉電(dian)源會(hui)縮(suo)短電(dian)池(chi)(chi)壽命(ming)" 的(de)說法，那(nei)么，真(zhen)的(de)是這樣嗎？

謠言：在充電前得先把電量完全耗盡

智慧(hui)手機(ji)用(yong)的(de)是鋰(li)離子(zi)(Li-ion)電(dian)(dian)(dian)池(chi)，不像傳統鎳(nie)鎘電(dian)(dian)(dian)池(chi)或鎳(nie)氫電(dian)(dian)(dian)池(chi)有電(dian)(dian)(dian)量(liang)記憶問題，因此也不用(yong)在(zai)充電(dian)(dian)(dian)前把電(dian)(dian)(dian)量(liang)耗盡(jin)。鋰(li)離子(zi)電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)量(liang)計算方式也和傳統電(dian)(dian)(dian)池(chi)不同，使(shi)用(yong)者毋(wu)須擔心會發生(sheng)過度充電(dian)(dian)(dian)的(de)問題。但(dan)許多制造商仍(reng)會建議使(shi)用(yong)者，每(mei)隔一到三(san)個月就將電(dian)(dian)(dian)量(liang)耗盡(jin)并徹(che)底充電(dian)(dian)(dian)一次(ci)，藉以“調校”(Calibrate)電(dian)(dian)(dian)池(chi)狀態。

現在(zai)的(de)(de)智能手機都用的(de)(de)是鋰離子(zi)電(dian)(dian)池(chi)(chi)(chi), 不像傳統(tong)的(de)(de)鎳鎘電(dian)(dian)池(chi)(chi)(chi)或鎳氫電(dian)(dian)池(chi)(chi)(chi)有電(dian)(dian)量記(ji)憶問題, 所以在(zai)不用耗盡電(dian)(dian)量也能無傷充(chong)(chong)電(dian)(dian)。而且鋰離子(zi)電(dian)(dian)池(chi)(chi)(chi)的(de)(de)功率計算也不同于傳統(tong)的(de)(de)電(dian)(dian)池(chi)(chi)(chi), 用戶不必(bi)擔心充(chong)(chong)電(dian)(dian)一晚上(shang)不拔的(de)(de)問題。不過最好還是, 每三個月就(jiu)用盡一次,然后完全充(chong)(chong)電(dian)(dian)一次, 以 "校準(zhun)" 電(dian)(dian)池(chi)(chi)(chi)的(de)(de)狀態.

年少的(de)時候，“四驅(qu)車兄弟”火(huo)極一時，那時候，每(mei)個男孩子都渴(ke)望得到(dao)一輛帥氣的(de)四驅(qu)車。限于(yu)當(dang)時多數電(dian)動(dong)玩具是5號(hao)電(dian)池驅(qu)動(dong)，男孩子們為了(le)節(jie)約成本，多會去(qu)購(gou)買5號(hao)充電(dian)電(dian)池。相對應的(de)，會有形色各異的(de)5號(hao)電(dian)池充電(dian)器.

5號充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池額(e)定(ding)電(dian)(dian)(dian)(dian)(dian)壓為(wei)1.2V，當(dang)四驅車跑不動時，實(shi)際(ji)是(shi)因電(dian)(dian)(dian)(dian)(dian)解(jie)質內離子用(yong)盡，電(dian)(dian)(dian)(dian)(dian)壓僅能達(da)到1V以下。充電(dian)(dian)(dian)(dian)(dian)時，充電(dian)(dian)(dian)(dian)(dian)器兩端電(dian)(dian)(dian)(dian)(dian)壓恒定(ding)到1.2V，即可因電(dian)(dian)(dian)(dian)(dian)勢差引(yin)起電(dian)(dian)(dian)(dian)(dian)池內的離子移動。當(dang)電(dian)(dian)(dian)(dian)(dian)池充滿(man)，電(dian)(dian)(dian)(dian)(dian)壓恢復1.2V，電(dian)(dian)(dian)(dian)(dian)池充滿(man)。

可(ke)是(shi)，電池是(shi)一個(ge)極(ji)(ji)(ji)其完美(mei)的(de)化(hua)學反(fan)應“燒(shao)杯”，存在外接電源的(de)情況(kuang)下，會(hui)形(xing)成(cheng)(cheng)陰極(ji)(ji)(ji)-陽極(ji)(ji)(ji)的(de)通路。這時，雖然(ran)電壓穩(wen)定，但正負極(ji)(ji)(ji)仍然(ran)進行著復雜的(de)化(hua)學反(fan)應。導(dao)致兩個(ge)結果：電池溫度上升、陰陽極(ji)(ji)(ji)微觀結構(gou)變化(hua)。比如，早期的(de)鎳鎘(ge)電池，過充化(hua)學反(fan)應會(hui)形(xing)成(cheng)(cheng)微氣(qi)泡，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(hua)，充電(dian)時關機有利于電(dian)池的保養。做(zuo)不到，也(ye)別邊(bian)充電(dian)邊(bian)玩手機，除了傷(shang)害手機電(dian)池，對(dui)人(ren)體(ti)也(ye)有害。畢竟換你餓了正在吃飯，要是還(huan)被逼(bi)著工作，身(shen)體(ti)吃不消(xiao)不說(shuo)，咬(yao)老板一口(kou)的心也(ye)會有。對(dui)小蘋果好一點，畢竟是身(shen)上掉(diao)下來(lai)的“腎”吶~~

蘋果(guo)這樣的(de)互聯網巨頭公(gong)司，可(ke)怕就可(ke)怕在每一(yi)個細節(jie)都會讓人感覺到(dao)(dao)它領先其他手(shou)機(ji)廠家好幾(ji)條(tiao)街：iphone5s之(zhi)后(hou)的(de)機(ji)型，會檢(jian)測充電器插上(shang)的(de)次數(shu)，或者是電池的(de)電壓，如果(guo)你不(bu)拔掉充電器，在手(shou)機(ji)充滿電之(zhi)后(hou)，電源管理器就會自動停止充電，開始放點，放出(chu)5%以(yi)后(hou)，再充電，如此循環，直到(dao)(dao)你拔掉為止。

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。
