I8000 Froyo android 2.2 beta1 Battery draining very quickly ( 電力消耗異常快)

I am testing Froyo andriod 2.2 on my I8000 phone for the last few days n very satisfied with its performance. Although the bluebooth function is still not working, everything else seems working fine expect the battery. My battery is draining very quickly even when the phone is on sleep mode. (And u can also feel that the temperature of your phone running android is higher then running WM ) I checked the "battery use" option on my phone and realized a process called "cell standby" use a lots of power whenever the phone is on normal or sleep mode. Did some search on google, I found that it could be caused by the high level of signal strength of the phone.

Someone suggest the following method to fix that and it work for me. Not only make the battery last longer, but also reduce the temperature of my phone as well. So I posted it here.

原來的時候 (Before applying the method)

設定完之後 (After applying the method)

Tried the 'Airplane Mode' workaround/trick?

1.Activate 'Airplane mode' on the phone.
2.Wait and let it go to sleep of its own accord.(it will take around 1min to get into sleep mode)
3.Wake up the phone after a short while and deactivate Airplane mode'

Someone said there I8000 android can last for up to 48 hours without charging. However,in my experience, I can only last 7 hours with 3G connection on. If you know anything about extend the battery life. Please let me KNOW!

=========================================================

在Samsung I8000 試用了 Froyo andriod 2.2幾天 . 感覺非常好. 除了BLUETOOTH 不能用. 其它的功能大致上OK. 但唯獨有一個問題困擾我, 就是電池消耗異常快. 1-2小時之內電池就耗盡(即使處於待機模式也是). 電話機身的溫度亦明顯比運行WM 的時候為高. 我查看電話的 "battery use"選項, 發現cell standby 的用電量比其它一個都要高很多.  GOOGLE 了一下之後, 發覺原因可能是它的signal strength 一直處於高的狀態, 從而導致使用過多的電量.

減低cell standby 用電量的方法, 可以嘗試以下步驟:
1.啟用 "Airplane mode" (即使讓電話不使用任何3G/WIFI)
2.等待電話自己進入待機. (太約等一分鐘就會進入待機模式, 然後再等多30秒)
3. 開啟電話, 禁用 "Airplane mode".

完成以上步驟之後, 你會發覺cell standby 的用電量明顯少了很多. 機身溫度也沒那麼高.

有人說可以持續使用I8000 ANDRIOD 48小時不用充電. 但是我試過在3G MODE 最多只有7小時便沒有電. 如果你知道有什麼可以延長電池壽命的方法, 請告訴我. THX!
