有消(xiao)息稱新(xin)iPad充(chong)電(dian)(dian)使用充(chong)電(dian)(dian)器充(chong)電(dian)(dian)顯示達(da)到(dao)100%后，繼續再(zai)充(chong)一(yi)小時仍然無法(fa)達(da)到(dao)真正的滿電(dian)(dian)狀態，也許(xu)讓新(xin)iPad充(chong)更多(duo)的時間可能是一(yi)個好方(fang)法(fa)，但實際上這不(bu)是最佳方(fang)案。

      因為(wei)在這(zhe)(zhe)里忽略了(le)鋰離子電(dian)池(chi)(chi)的(de)壽(shou)命(ming)(ming)問題。這(zhe)(zhe)就存在一個每次充(chong)電(dian)飽滿程(cheng)度和電(dian)池(chi)(chi)整個壽(shou)命(ming)(ming)的(de)權(quan)衡問題。電(dian)池(chi)(chi)是有(you)壽(shou)命(ming)(ming)限(xian)制的(de)，最后會失去充(chong)電(dian)的(de)能力。長(chang)時間(jian)的(de)充(chong)電(dian)會導致(zhi)電(dian)池(chi)(chi)加速退化，最終將毀(hui)掉電(dian)池(chi)(chi)。經過(guo)對電(dian)池(chi)(chi)的(de)研(yan)究發現(xian)，充(chong)電(dian)時間(jian)的(de)長(chang)短決定了(le)電(dian)池(chi)(chi)的(de)壽(shou)命(ming)(ming)。

     有數據顯(xian)示iPad充(chong)(chong)(chong)電(dian)(dian)(dian)時的溫度會達(da)到86F （30C）左右，但是飽和充(chong)(chong)(chong)電(dian)(dian)(dian)和60%充(chong)(chong)(chong)電(dian)(dian)(dian)是有本質的區別(bie)的。如果(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)保持在40%左右時，電(dian)(dian)(dian)池每年將縮(suo)短4%的壽命，而在每次充(chong)(chong)(chong)滿電(dian)(dian)(dian)的情(qing)況下(xia)，電(dian)(dian)(dian)池每年將縮(suo)短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充電顯示信息，但這是(shi)無可(ke)厚非的。不管怎樣(yang)，不要讓iPad充電太久。
