有消息稱新iPad充(chong)電(dian)使用(yong)充(chong)電(dian)器充(chong)電(dian)顯示達(da)到(dao)100%后，繼續再(zai)充(chong)一小時仍然無法(fa)達(da)到(dao)真正的(de)滿電(dian)狀態，也許讓(rang)新iPad充(chong)更(geng)多(duo)的(de)時間可能是一個好方法(fa)，但實際上(shang)這不是最佳方案。

      因(yin)為在這里忽略了鋰離子電(dian)(dian)池(chi)的(de)(de)(de)壽(shou)命(ming)(ming)問(wen)題。這就存(cun)在一個(ge)每次充電(dian)(dian)飽滿程(cheng)度和(he)電(dian)(dian)池(chi)整個(ge)壽(shou)命(ming)(ming)的(de)(de)(de)權衡問(wen)題。電(dian)(dian)池(chi)是(shi)有壽(shou)命(ming)(ming)限制的(de)(de)(de)，最(zui)(zui)后會失(shi)去充電(dian)(dian)的(de)(de)(de)能力。長時(shi)間(jian)的(de)(de)(de)充電(dian)(dian)會導致電(dian)(dian)池(chi)加速退化，最(zui)(zui)終將毀掉電(dian)(dian)池(chi)。經(jing)過對(dui)電(dian)(dian)池(chi)的(de)(de)(de)研究發(fa)現，充電(dian)(dian)時(shi)間(jian)的(de)(de)(de)長短決定(ding)了電(dian)(dian)池(chi)的(de)(de)(de)壽(shou)命(ming)(ming)。

     有數據(ju)顯示iPad充(chong)(chong)(chong)電(dian)(dian)時(shi)的溫(wen)度會達到86F （30C）左(zuo)右，但(dan)是飽和充(chong)(chong)(chong)電(dian)(dian)和60%充(chong)(chong)(chong)電(dian)(dian)是有本(ben)質的區別的。如(ru)果充(chong)(chong)(chong)電(dian)(dian)保持在(zai)40%左(zuo)右時(shi)，電(dian)(dian)池每(mei)(mei)年(nian)將縮(suo)短(duan)4%的壽命，而在(zai)每(mei)(mei)次充(chong)(chong)(chong)滿電(dian)(dian)的情況下，電(dian)(dian)池每(mei)(mei)年(nian)將縮(suo)短(duan)20%的壽命。

    也許蘋果正式考慮了這個因素，為了保護電池的壽命，設置了電池充電器錯誤的(de)充電顯示信息，但這是(shi)無可(ke)厚(hou)非的(de)。不管怎樣，不要讓iPad充電太久。
