Poor Battery Life related to Data

[mgartner0622]

Hello All,

I currently have an Jailbroken and Unlocked iPhone 3GS. About 4 days ago the battery started having issues.

On a normal day, at most I can get less than 2 hours out of the battery. I have no applications installed, and the only thing I have configured is MobileMe. (This is without using the phone, in standby the whole time.)

HOWEVER, If I turn the Cellular Data Network off, I can get through a whole day with the battery still at 100 or 99%.

What could the issue possibly be? Related to Jailbreak? or do I need a new battery? Also, If i put the phone on Airplane Mode with WiFi on, the same issue happens.

Thank you for your help.

Well it seems to me, and you said it yourself that if you turn off the cullular data option, your battery lasts. However, the second you turn it back on, it seems that since you have jailbroken your iPhone, it is constantly sending data somehow.

It sounds very strange, but it appears that data constantly being sent out from the phone.

I don't have Iphone 3GS, but Iphone4. My battery drainage is similar to your story. Every time I preform a task (text,youtube, surf, email, etc etc) it will drop 1%. I thought it was dead battery so sent me a new replacement, which I got today and testing it out

Jailbreak have nothing to do with battery drainage since I jailbroken my Iphone4 months ago and battery is fine, before this happen.

Finally, either At&t Data network is *beep* our battery. My problem started after Oct.

Yes, I believe you're right.
I just went to Settings>General>Usage
Apparently, (All ive done in the past 2 days since i've restored it is sent 2 pictures via email) I've sent over 500MB of Data, and Recieved over 2GB!!!!
What could this be? Again, the only thing I have is MobileMe and the jailbreak...

Did you call At&t about this matter? I'm still testing out the new device out before I call. I'm not sure if Apple will solve this problem by giving me another third Iphone4.

I have more programs install in Cydia, so Jailbreak don't drain (some might improve it). ..I even check other forum to confirm on this matter.
