当手机的电池使用时间短的时候,应该考虑下重新校准下电池了,而不是像以前有文章说的在冰箱中冻24小时拿出后再充电。

下面华为手机电池重新校准的方法是在国外的一个论坛上看到的，是U8800的，别的型号也可以适用吧, 没有亲测：

1. 将手机连接到充电器，对手机充电，直到通知指示灯变成绿色的，手机充电到100%。
2. 断开手机充电器，并将手机关机。
3. 手机关机的情况下, 重新连接充电器，让手机充电30分钟。
4. 断开手机充电器, 并开机。
5. 手机开机完成后，再次关机，并重新连接到充电器,充电30分钟。
6. 断开充电器，重新开机，电池状态被清除掉, 电池校准完成。

You will need ClockworkMod installed to do this. I try and do this every time I install a new ROM.
If you are suffering from poor battery life this process should help boost the performance.

1 Connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
2 Disconnect the phone from the charger, and power it off.
3 Reconnect the phone to the charger with the phone powered off, and allow the phone to charge for 30mins.
4 Disconnect the phone from the charger and power it on.
5 Once the phone is powered completely on, power it off again and reconnect it to the charger for another 30mins.
6 Disconnect the phone, power it on in clockwork recovery, and wipe batt stats.
