現今智能手機(ji)的(de)(de)(de)功能越來(lai)越強(qiang)大(da)，但續(xu)航依舊是痛點，為此不少廠商通過(guo)加大(da)電池(chi)容(rong)量(liang)和增加快充來(lai)彌(mi)補。不少用戶也希望通過(guo)保養電池(chi)來(lai)讓手機(ji)用的(de)(de)(de)時間更(geng)長些，所以網上就有了"不充滿電就拔(ba)掉電源會縮短電池(chi)壽命" 的(de)(de)(de)說法，那么，真(zhen)的(de)(de)(de)是這樣(yang)嗎？

謠言：在充電前得先把電量完全耗盡

智慧手機用(yong)(yong)的是鋰離子(Li-ion)電(dian)(dian)(dian)池(chi)(chi)，不(bu)像傳(chuan)統(tong)鎳(nie)鎘電(dian)(dian)(dian)池(chi)(chi)或鎳(nie)氫電(dian)(dian)(dian)池(chi)(chi)有電(dian)(dian)(dian)量(liang)記憶(yi)問題(ti)，因此也不(bu)用(yong)(yong)在充(chong)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(ji)算方(fang)式也和傳(chuan)統(tong)電(dian)(dian)(dian)池(chi)(chi)不(bu)同(tong)，使(shi)用(yong)(yong)者毋須擔心會(hui)發(fa)生過度(du)充(chong)電(dian)(dian)(dian)的問題(ti)。但許(xu)多制造商仍會(hui)建(jian)議使(shi)用(yong)(yong)者，每隔(ge)一(yi)到三個月就將電(dian)(dian)(dian)量(liang)耗盡并徹底充(chong)電(dian)(dian)(dian)一(yi)次(ci)，藉以“調校”(Calibrate)電(dian)(dian)(dian)池(chi)(chi)狀態。

現在的智能手機(ji)都用(yong)的是(shi)鋰離子電(dian)(dian)池(chi)(chi), 不像傳統(tong)的鎳鎘電(dian)(dian)池(chi)(chi)或鎳氫(qing)電(dian)(dian)池(chi)(chi)有電(dian)(dian)量(liang)記憶問(wen)題, 所以在不用(yong)耗盡電(dian)(dian)量(liang)也能無傷充電(dian)(dian)。而且鋰離子電(dian)(dian)池(chi)(chi)的功率(lv)計(ji)算也不同于傳統(tong)的電(dian)(dian)池(chi)(chi), 用(yong)戶不必擔心充電(dian)(dian)一晚(wan)上不拔的問(wen)題。不過最(zui)好(hao)還(huan)是(shi), 每三個月(yue)就用(yong)盡一次,然后(hou)完全充電(dian)(dian)一次, 以 "校(xiao)準(zhun)" 電(dian)(dian)池(chi)(chi)的狀(zhuang)態.

年少(shao)的(de)(de)(de)時候(hou)，“四驅車兄弟”火(huo)極一時，那時候(hou)，每個男孩子(zi)都(dou)渴望得(de)到一輛帥(shuai)氣的(de)(de)(de)四驅車。限于當時多數電(dian)動玩具是(shi)5號(hao)電(dian)池驅動，男孩子(zi)們為了節(jie)約成本(ben)，多會去購買(mai)5號(hao)充(chong)(chong)電(dian)電(dian)池。相對(dui)應的(de)(de)(de)，會有形色各異的(de)(de)(de)5號(hao)電(dian)池充(chong)(chong)電(dian)器.

5號(hao)充電(dian)電(dian)池(chi)額定(ding)電(dian)壓為1.2V，當四驅車跑不動時，實(shi)際(ji)是因(yin)電(dian)解質內(nei)離子用盡，電(dian)壓僅能達到1V以下。充電(dian)時，充電(dian)器兩端(duan)電(dian)壓恒(heng)定(ding)到1.2V，即可因(yin)電(dian)勢差引起(qi)電(dian)池(chi)內(nei)的離子移(yi)動。當電(dian)池(chi)充滿，電(dian)壓恢(hui)復(fu)1.2V，電(dian)池(chi)充滿。

可是(shi)，電(dian)池是(shi)一個極(ji)其完美的化學反應(ying)“燒杯(bei)”，存在外接電(dian)源的情(qing)況下，會(hui)(hui)形(xing)成陰極(ji)-陽極(ji)的通路(lu)。這時，雖然(ran)電(dian)壓(ya)穩定，但正(zheng)負極(ji)仍(reng)然(ran)進(jin)行(xing)著復雜的化學反應(ying)。導致兩(liang)個結果：電(dian)池溫度上升、陰陽極(ji)微(wei)觀結構變化。比(bi)如，早期的鎳鎘電(dian)池，過(guo)充化學反應(ying)會(hui)(hui)形(xing)成微(wei)氣泡，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？

情況允(yun)許(xu)的(de)話，充電(dian)時關(guan)機(ji)有(you)(you)利于電(dian)池的(de)保(bao)養。做不(bu)(bu)到，也別邊充電(dian)邊玩(wan)手(shou)機(ji)，除了傷害手(shou)機(ji)電(dian)池，對(dui)(dui)人體(ti)也有(you)(you)害。畢竟(jing)換你餓了正在吃(chi)飯(fan)，要(yao)是(shi)還被逼著工作，身體(ti)吃(chi)不(bu)(bu)消不(bu)(bu)說，咬老(lao)板一口的(de)心也會(hui)有(you)(you)。對(dui)(dui)小(xiao)蘋果好一點，畢竟(jing)是(shi)身上(shang)掉下來(lai)的(de)“腎”吶~~

蘋(pin)果這樣的(de)互聯網巨頭公(gong)司(si)，可怕就可怕在每一個細節(jie)都會讓人感覺到它領(ling)先其他手機廠家好幾條街(jie)：iphone5s之后(hou)的(de)機型，會檢測充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)插上的(de)次(ci)數，或者是(shi)電(dian)(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)(dian)壓，如果你(ni)(ni)不(bu)拔掉充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，在手機充(chong)滿電(dian)(dian)(dian)(dian)(dian)之后(hou)，電(dian)(dian)(dian)(dian)(dian)源管理器(qi)(qi)就會自動停(ting)止(zhi)充(chong)電(dian)(dian)(dian)(dian)(dian)，開始放(fang)點，放(fang)出5%以后(hou)，再充(chong)電(dian)(dian)(dian)(dian)(dian)，如此(ci)循(xun)環，直到你(ni)(ni)拔掉為止(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。
