有消息稱新iPad充電(dian)使用(yong)充電(dian)器充電(dian)顯示(shi)達到(dao)100%后，繼(ji)續再充一小時仍然無法(fa)(fa)達到(dao)真正(zheng)的(de)滿電(dian)狀態(tai)，也許讓(rang)新iPad充更多的(de)時間可能(neng)是(shi)一個好方法(fa)(fa)，但實際上(shang)這不是(shi)最佳方案。

      因為在這里(li)忽略了鋰離子電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)壽命(ming)(ming)(ming)問(wen)題。這就存(cun)在一個每次(ci)充電(dian)(dian)(dian)飽滿程度(du)和(he)電(dian)(dian)(dian)池(chi)(chi)整個壽命(ming)(ming)(ming)的(de)(de)(de)(de)(de)權衡(heng)問(wen)題。電(dian)(dian)(dian)池(chi)(chi)是有壽命(ming)(ming)(ming)限制的(de)(de)(de)(de)(de)，最后(hou)會(hui)失去充電(dian)(dian)(dian)的(de)(de)(de)(de)(de)能力。長時(shi)間的(de)(de)(de)(de)(de)充電(dian)(dian)(dian)會(hui)導致電(dian)(dian)(dian)池(chi)(chi)加速(su)退化，最終將毀掉(diao)電(dian)(dian)(dian)池(chi)(chi)。經過(guo)對電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)研究(jiu)發現，充電(dian)(dian)(dian)時(shi)間的(de)(de)(de)(de)(de)長短決定了電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)(de)壽命(ming)(ming)(ming)。

     有數(shu)據顯示iPad充(chong)電(dian)(dian)(dian)時的(de)溫度(du)會達到86F （30C）左(zuo)(zuo)右(you)，但是飽和(he)充(chong)電(dian)(dian)(dian)和(he)60%充(chong)電(dian)(dian)(dian)是有本質的(de)區別(bie)的(de)。如果充(chong)電(dian)(dian)(dian)保(bao)持在40%左(zuo)(zuo)右(you)時，電(dian)(dian)(dian)池每(mei)年將縮短(duan)4%的(de)壽命，而在每(mei)次充(chong)滿電(dian)(dian)(dian)的(de)情況下，電(dian)(dian)(dian)池每(mei)年將縮短(duan)20%的(de)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(cuo)誤的充(chong)(chong)電顯(xian)示(shi)信息(xi)，但這是(shi)無可厚非(fei)的。不(bu)管(guan)怎樣，不(bu)要讓iPad充(chong)(chong)電太久。
