如果你有jb後耗電量大增 找不到問題無法解決 這方法對你也許有用

感謝作者yungyao全文轉貼自 http://www.mobile01.com/topicdetail.php?f=591&t=1818817&last=24086021

因為目前ios更新到了 4.2.1 而 MobileSubstrate 目前也更新到了 3367-1
底下的更改到3228-1 已經沒用了(裝程式可能會被自動更新成3367-1)
所以要更改的版本號可以改成3367-1 就不會被自動更新
日後等到版本比較沒問題之後再升上去

----------------------------------------------------------------------------

自從4.1可以jb後 相信有不少人會感覺到耗電量增加得很快
以我個人來說 有滿大的差別 以待機一個晚上來說 耗電大約1-3% (只關推撥)
jb後灌了一些軟體 (只關推撥) 有一個晚上待機就掉80%電力的
也有一個晚上掉20%電力 (睡前都是充飽100% 背景後台app都關)
看了一些討論 也確實滿多人有這種情況
前天看了某論壇有發現 引起耗電問題的罪魁禍首有可能就是「MobileSubstrate」這個插件
你可以簡單的移除他 但是有滿多cydia裝的程式需要這個插件 例 sbsettings、mqucikdo .....
但是發現耗電主因是 mobilesubstrate_0.9.3228-1 版(最新版) 而mobilesubstrate_0.9.3209-1 並無耗電問題
所以各位如果感覺耗電嚴重的，可以嘗試將「MobileSubstrate」降級到 3209 版
我個人是測試了兩天 一樣也是只關推撥 晚上待機到早上 耗電量只有2% 未降版前是15-20%

以下是更改方法 再說一次 這方法對我有效 但不一定對你們有效
如果對你有效而得到改善 那恭喜你 但如果對你無效 也請不要鞭我.........

底下是回復到4.1 重新jb(我是用greenpois0n-rc4) 設定成新的iphone 再往下看

1 先下載「MobileSubstrate」3209版 (附件)
2 下載ifile 和 (i-funbox 需要先裝afc2add cydia 選search 打afc2add安裝 )
3 打開i-funbox 把mobilesubstrate_0.9.3209-1 copy到 /var/mobile.底下
用ifile 打開 mobilesubstrate_0.9.3209-1 install 裝完會重啟
4 如果沒ifile 可以用i-funbox 把
mobilesubstrate_0.9.3209-1 copy到 /private/var/root/Media/Cydia/AutoInstall 下 然後重啟
他會幫你自動安裝 安裝完會在自動重啟一次
5 因為是舊版 比3228低一版 所以如果你有裝需用到mobilesubstrate的程式 有時他會把你自動更新
這樣就作白工了 所以還要再修改一個檔案 一樣用i-funbox 到/private/var/lib/dpkg 這目錄下
你會看到status 這個檔 把他copy 出來 用ultraedit打開 搜尋 mobilesubstrate 將底下一行裡面的
Version: 0.9.3209-1」改為「Version: 0.9.3228-1 (把09改成28就好 其他不要動到) 改完再copy回去
這樣就可以騙過 Cydia，令其以為 mobilesubstrate 已經是最新版本。再安裝其他軟件，
也不會自動更新了

如果不想重刷機 而想直接降版也是可以 方法也是如上大同小異
最後再提醒一次 希望有能力自己能恢復系統 及jb的人在嘗試
萬一修改後有什麼問題 可自行回復4.1系統及jb

10-30 昨天待機測試 補2張圖 只關推撥 藍芽

[vicjang]

現在有 0.9.3367-1 囉

說不定也可以解決問題, 可以試試看

(我是 iPod touch 4th 狀況可能跟 IP4 不同, 但我用起來很好)

[shihwinwin]

這我用過了～但是還感受不出來他的效用
缺點是 目前我的cydia 無法正常升級了...

[kresion]

千萬別用 mobile01根本鳥論壇 這讓非常多人白蘋果還無法重刷出現一堆問題

[markteng77]

這篇已經有人發過了https://iphone4.tw/forums/showthread.php?t=106679

問題很多, 最好別用!!!!

好犀利的發言阿...

[randy0722]

極容易白蘋果，不要用

[kominechin]

同意 我親身測試過 白蘋果了一整天 ....
更新至3367-1之後 有比之前好一點

The recently released PwnageTool / Redsn0w jailbreak tools for iOS 4.2.1 requires you to transfer iPad’s 3.2.2 baseband to your iPhone 3GS & 3G in order to unlock it using Ultrasn0w 1.2. This has resulted in poor battery performance as has been experienced by many users. Some users have also complained about their device becoming very hot when in use.



An official fix for this problem is currently being worked on, and it will be released on Cydia when ready. But in the meantime, you can try one of the following methods to temporary fix the issue:

Method 1: The first method requires you or a friend to have the official iPhone SIM card. What you need to do is put that SIM in the iPhone and let it activate officially. It will even work if the SIM card is not active in that country or is dead. Once your iPhone is activated with this SIM card, you can then take it out and switch back to whichever one you like.

Method 2: If you cannot get hold of an official SIM card, a temporary fix is to install SBSettings and turn your 3G off every time you are done using it. This will prevent the battery drain issue but is slightly tedious and annoying.

Method 3: This method is not available yet but a Dev-Team member is said to be working on an official fix for this issue. Once released on Cydia, all you will need to do is install it to your iPhone.

Here is the statement from Sherif Hashim:

On a very important side note, before anyone starts to complain about battery drainage issues after installing the new ultrasn0w on the 6.15.00 updated BB, the culprit here is not ultrasn0w, it’s the hacktivation process (activating the phone by pwnage tool or redsn0w rather than using an official carrier sim to do so) that u mostly did while jailbreaking.

The 4.1 and 4.2.1 ipsws unlike their old ancestors, seem to keep looking for valid push certificates all the time, either thru your wifi, or thru your cellular data network (which u only have after installing ultrasn0w and hence u accuse it) , this can be seen clearly if u have a cellular working data plan for 3g or edge and u watched the settings > general > usage > cellular network data (sent & received are continuously increasing even without using any internet traffics on the phone) , this will also render the phone going hot even in stand by mode and also very rapid battery drainage occurs plus consuming ur data if you were not on an unlimited plan.


所以,最好先用美版官方sim卡機活再jb應該就沒有問題了!!!這是官方的說法!!

抱歉離題 可以請問大大照片po的sbsettings的主題是什麼???
