今天凌晨1點,蘋果正式向國內用戶推送了iOS 9的正式版本,相對於iOS 8來說,新系統改進相當多,絕對值得你第一時間去升級。
iOS 9雖然沒有加入什麼重大新功能,但蘋果加強了它的易用性、穩定性,首先新系統大小只需1.3GB左右,其次它提升了電池續航,並加入低電量模式額外增加至3小時續航,最後iPad的分屏功能也加入進來了。
如果你OTA更新老是出錯,不妨下載下面的完整安裝鏡像,然後通過iTunes來更新吧,具體教程:
1、用數據線將設備連接上最新版iTunes,緊接著打開iTunes,
2、按住鍵盤上Shift,同時點擊iTunes的“更新”功能;
3、根據iTunes彈出對話窗,選擇對應版本的iOS 9固件,點擊更新即可。
