... i had the same problem when i was using Iphone 4s, (i think 5s has the same problem), better check your setting, turn off those push notifications n such, making sure those app like mail, facebook, or some game app are not CONSTANTLY updating or uploading your information. usually i often double click on the main button and turn off all apps that i am not using. this is very efficient to ensure the battery is full all day:)作者: 高飞 时间: 2014-1-2 11:20:26
