現今智能手機(ji)的(de)功能越(yue)來越(yue)強大(da)，但續航依舊是痛(tong)點，為此不(bu)少(shao)廠商通過加大(da)電(dian)池容量和(he)增(zeng)加快充(chong)來彌補。不(bu)少(shao)用(yong)戶也希望通過保養(yang)電(dian)池來讓手機(ji)用(yong)的(de)時間更長些，所(suo)以網上就(jiu)有了"不(bu)充(chong)滿電(dian)就(jiu)拔掉電(dian)源會縮短電(dian)池壽命" 的(de)說法，那(nei)么(me)，真的(de)是這樣嗎？

謠言：在充電前得先把電量完全耗盡

智慧(hui)手(shou)機用(yong)(yong)的是(shi)鋰離子(Li-ion)電(dian)(dian)(dian)池(chi)(chi)，不像傳統鎳鎘(ge)電(dian)(dian)(dian)池(chi)(chi)或鎳氫電(dian)(dian)(dian)池(chi)(chi)有(you)電(dian)(dian)(dian)量(liang)記憶問題，因此也(ye)不用(yong)(yong)在充電(dian)(dian)(dian)前把電(dian)(dian)(dian)量(liang)耗盡。鋰離子電(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)量(liang)計算(suan)方式(shi)也(ye)和傳統電(dian)(dian)(dian)池(chi)(chi)不同，使用(yong)(yong)者毋須擔(dan)心會發生過度(du)充電(dian)(dian)(dian)的問題。但許多(duo)制(zhi)造商仍會建議使用(yong)(yong)者，每隔一(yi)到三(san)個月就(jiu)將(jiang)電(dian)(dian)(dian)量(liang)耗盡并徹底充電(dian)(dian)(dian)一(yi)次，藉以“調(diao)校”(Calibrate)電(dian)(dian)(dian)池(chi)(chi)狀態。

現(xian)在(zai)的智能手(shou)機都用(yong)(yong)的是(shi)鋰離子(zi)電(dian)池, 不(bu)(bu)像(xiang)傳統的鎳鎘(ge)電(dian)池或鎳氫電(dian)池有電(dian)量記憶問(wen)題, 所以(yi)在(zai)不(bu)(bu)用(yong)(yong)耗(hao)盡(jin)電(dian)量也(ye)(ye)能無(wu)傷充電(dian)。而(er)且鋰離子(zi)電(dian)池的功率(lv)計(ji)算也(ye)(ye)不(bu)(bu)同于(yu)傳統的電(dian)池, 用(yong)(yong)戶不(bu)(bu)必(bi)擔心充電(dian)一(yi)晚上不(bu)(bu)拔的問(wen)題。不(bu)(bu)過最(zui)好(hao)還是(shi), 每三個月就用(yong)(yong)盡(jin)一(yi)次(ci),然(ran)后完全充電(dian)一(yi)次(ci), 以(yi) "校準" 電(dian)池的狀態.

年(nian)少的(de)(de)時候(hou)，“四驅車兄(xiong)弟”火(huo)極一(yi)時，那時候(hou)，每個男(nan)孩子(zi)都渴望得到一(yi)輛帥氣的(de)(de)四驅車。限于當時多數(shu)電動玩具是5號電池(chi)(chi)驅動，男(nan)孩子(zi)們(men)為了節約成本，多會(hui)去購買5號充(chong)電電池(chi)(chi)。相對應的(de)(de)，會(hui)有形色各(ge)異的(de)(de)5號電池(chi)(chi)充(chong)電器(qi).

5號(hao)充電(dian)(dian)(dian)電(dian)(dian)(dian)池額定電(dian)(dian)(dian)壓為(wei)1.2V，當四驅車跑不動(dong)(dong)時(shi)，實際是(shi)因(yin)電(dian)(dian)(dian)解質(zhi)內離子用盡，電(dian)(dian)(dian)壓僅能達到(dao)1V以(yi)下。充電(dian)(dian)(dian)時(shi)，充電(dian)(dian)(dian)器兩端電(dian)(dian)(dian)壓恒定到(dao)1.2V，即可因(yin)電(dian)(dian)(dian)勢(shi)差引起(qi)電(dian)(dian)(dian)池內的離子移動(dong)(dong)。當電(dian)(dian)(dian)池充滿，電(dian)(dian)(dian)壓恢復1.2V，電(dian)(dian)(dian)池充滿。

可是，電(dian)池(chi)是一個極其完美的(de)化學(xue)反(fan)應(ying)“燒(shao)杯(bei)”，存在外接(jie)電(dian)源的(de)情況下(xia)，會形成陰(yin)極-陽(yang)極的(de)通(tong)路(lu)。這時(shi)，雖然電(dian)壓穩定(ding)，但(dan)正負極仍(reng)然進行著復雜的(de)化學(xue)反(fan)應(ying)。導致兩個結果：電(dian)池(chi)溫度(du)上升、陰(yin)陽(yang)極微(wei)觀結構變化。比如，早期的(de)鎳鎘電(dian)池(chi)，過充化學(xue)反(fan)應(ying)會形成微(wei)氣泡(pao)，嚴(yan)重(zhong)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？

情況允許的話，充電(dian)(dian)時關機(ji)有(you)利(li)于電(dian)(dian)池的保養。做(zuo)不(bu)(bu)到(dao)，也別邊充電(dian)(dian)邊玩手(shou)機(ji)，除了傷害(hai)手(shou)機(ji)電(dian)(dian)池，對人體也有(you)害(hai)。畢(bi)竟(jing)換你餓了正在(zai)吃飯，要是還被逼著工作，身體吃不(bu)(bu)消不(bu)(bu)說，咬(yao)老板一口的心也會有(you)。對小蘋(pin)果(guo)好一點，畢(bi)竟(jing)是身上掉下來的“腎”吶~~

蘋果這樣的(de)互(hu)聯網巨頭公司，可(ke)怕(pa)(pa)就可(ke)怕(pa)(pa)在每一個細節(jie)都會(hui)(hui)讓人(ren)感覺到它領先其他(ta)手(shou)機(ji)廠家好幾條街(jie)：iphone5s之(zhi)后(hou)的(de)機(ji)型，會(hui)(hui)檢測(ce)充(chong)電(dian)(dian)器插(cha)上的(de)次數，或者(zhe)是電(dian)(dian)池的(de)電(dian)(dian)壓，如(ru)果你不(bu)拔(ba)掉充(chong)電(dian)(dian)器，在手(shou)機(ji)充(chong)滿電(dian)(dian)之(zhi)后(hou)，電(dian)(dian)源管(guan)理器就會(hui)(hui)自動停止(zhi)充(chong)電(dian)(dian)，開始放(fang)點，放(fang)出5%以后(hou)，再充(chong)電(dian)(dian)，如(ru)此循環，直到你拔(ba)掉為止(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。
