現今智能手機的(de)(de)功能越來(lai)(lai)越強大，但續(xu)航依舊是痛點，為此不(bu)少(shao)廠商通(tong)過(guo)加大電(dian)(dian)池容量和增加快充(chong)來(lai)(lai)彌補。不(bu)少(shao)用(yong)戶也希(xi)望通(tong)過(guo)保養(yang)電(dian)(dian)池來(lai)(lai)讓手機用(yong)的(de)(de)時(shi)間更(geng)長些，所以網上(shang)就有了"不(bu)充(chong)滿電(dian)(dian)就拔掉電(dian)(dian)源會縮短電(dian)(dian)池壽命" 的(de)(de)說法，那么(me)，真(zhen)的(de)(de)是這樣嗎？

謠言：在充電前得先把電量完全耗盡

智慧手機用的(de)是鋰離子(zi)(Li-ion)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，不(bu)像(xiang)傳統鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)或鎳氫電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)有電(dian)(dian)(dian)(dian)量(liang)記憶問題，因此(ci)也不(bu)用在充電(dian)(dian)(dian)(dian)前把電(dian)(dian)(dian)(dian)量(liang)耗(hao)盡。鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)量(liang)計算方式也和傳統電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)不(bu)同，使用者毋須擔(dan)心會發生過度充電(dian)(dian)(dian)(dian)的(de)問題。但許多制造商仍會建議使用者，每隔(ge)一(yi)到(dao)三(san)個月就(jiu)將電(dian)(dian)(dian)(dian)量(liang)耗(hao)盡并徹底充電(dian)(dian)(dian)(dian)一(yi)次(ci)，藉以(yi)“調校”(Calibrate)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)狀態。

現在(zai)的(de)(de)智能(neng)手機都用的(de)(de)是鋰(li)離子電(dian)(dian)(dian)池(chi), 不(bu)像傳統的(de)(de)鎳(nie)鎘電(dian)(dian)(dian)池(chi)或(huo)鎳(nie)氫電(dian)(dian)(dian)池(chi)有(you)電(dian)(dian)(dian)量記憶問(wen)題, 所以在(zai)不(bu)用耗盡(jin)電(dian)(dian)(dian)量也能(neng)無(wu)傷充(chong)電(dian)(dian)(dian)。而(er)且(qie)鋰(li)離子電(dian)(dian)(dian)池(chi)的(de)(de)功率計算(suan)也不(bu)同于傳統的(de)(de)電(dian)(dian)(dian)池(chi), 用戶不(bu)必擔心(xin)充(chong)電(dian)(dian)(dian)一(yi)(yi)晚上(shang)不(bu)拔的(de)(de)問(wen)題。不(bu)過最好(hao)還是, 每三個月就用盡(jin)一(yi)(yi)次(ci)(ci),然后完全充(chong)電(dian)(dian)(dian)一(yi)(yi)次(ci)(ci), 以 "校準" 電(dian)(dian)(dian)池(chi)的(de)(de)狀態.

年少的(de)(de)(de)時候，“四(si)驅(qu)車(che)兄弟(di)”火極一時，那(nei)時候，每(mei)個男(nan)孩子(zi)都渴(ke)望(wang)得到一輛帥氣的(de)(de)(de)四(si)驅(qu)車(che)。限于當時多(duo)數電(dian)(dian)動玩(wan)具是5號電(dian)(dian)池(chi)驅(qu)動，男(nan)孩子(zi)們(men)為(wei)了節約成(cheng)本，多(duo)會去購買5號充電(dian)(dian)電(dian)(dian)池(chi)。相對應的(de)(de)(de)，會有(you)形色各異的(de)(de)(de)5號電(dian)(dian)池(chi)充電(dian)(dian)器(qi).

5號充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)額定電(dian)(dian)(dian)壓為1.2V，當四驅(qu)車跑不動(dong)時(shi)，實際是(shi)因電(dian)(dian)(dian)解質內(nei)離子(zi)用盡，電(dian)(dian)(dian)壓僅能達到1V以下。充(chong)電(dian)(dian)(dian)時(shi)，充(chong)電(dian)(dian)(dian)器兩端電(dian)(dian)(dian)壓恒定到1.2V，即可因電(dian)(dian)(dian)勢差引起電(dian)(dian)(dian)池(chi)(chi)內(nei)的離子(zi)移(yi)動(dong)。當電(dian)(dian)(dian)池(chi)(chi)充(chong)滿(man)(man)，電(dian)(dian)(dian)壓恢復1.2V，電(dian)(dian)(dian)池(chi)(chi)充(chong)滿(man)(man)。

可是(shi)，電池(chi)是(shi)一個(ge)極其完美的化(hua)學(xue)反(fan)應(ying)(ying)“燒(shao)杯(bei)”，存在外接電源的情況下，會形(xing)成(cheng)(cheng)陰極-陽極的通路。這時，雖然電壓(ya)穩(wen)定，但正(zheng)負極仍然進行著復雜的化(hua)學(xue)反(fan)應(ying)(ying)。導致兩個(ge)結果：電池(chi)溫度(du)上升、陰陽極微觀結構變化(hua)。比如，早期的鎳鎘電池(chi)，過充化(hua)學(xue)反(fan)應(ying)(ying)會形(xing)成(cheng)(cheng)微氣泡，嚴重(zhong)影(ying)響性(xing)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？

情況允(yun)許的(de)話，充(chong)電時關機(ji)有利于電池的(de)保養。做(zuo)不到，也(ye)(ye)(ye)別邊充(chong)電邊玩手(shou)機(ji)，除了(le)傷害手(shou)機(ji)電池，對(dui)人體也(ye)(ye)(ye)有害。畢竟換你餓了(le)正(zheng)在吃(chi)飯，要(yao)是(shi)還被逼著工作，身體吃(chi)不消不說，咬老板(ban)一口的(de)心也(ye)(ye)(ye)會有。對(dui)小蘋(pin)果好一點，畢竟是(shi)身上掉下來的(de)“腎(shen)”吶~~

蘋果(guo)這樣的互聯網巨頭(tou)公(gong)司，可怕就可怕在每一個細(xi)節都會讓人感覺到(dao)它領先其他手機廠家好(hao)幾條街：iphone5s之后的機型，會檢測充電(dian)(dian)(dian)器(qi)插上的次數，或(huo)者是電(dian)(dian)(dian)池的電(dian)(dian)(dian)壓，如果(guo)你不拔掉(diao)(diao)充電(dian)(dian)(dian)器(qi)，在手機充滿電(dian)(dian)(dian)之后，電(dian)(dian)(dian)源管理(li)器(qi)就會自(zi)動(dong)停止(zhi)充電(dian)(dian)(dian)，開(kai)始(shi)放點，放出5%以(yi)后，再充電(dian)(dian)(dian)，如此循環，直到(dao)你拔掉(diao)(diao)為止(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。
