Battery Drain after jailbreak+unlock of iPhone 4 32 GB! Help please?!

Hi everyone. For a while I've been..um... forgot that word that means "looking through forums but not having a username or posting". But I've come to the point of not finding any answers for the situation I'm stuck in right now. I hope you guys can help me.

So I bought my phone non-contracted on release day in California. Been using it as an iPod touch pretty much until this past week when the jailbreak/unlock came out. I needed the unlock for T-mobile pretty much. Before the jailbreak/unlock, I was getting battery life of around 3 days, on and off usage. I was super impressed by the battery life of the phone because I was doing a lot and not charging much at all.

However, after I jailbroke and unlocked my phone, I've been getting a 5% per hour drainage consistently on standby. I've done everything I can to try to remedy it and nothing has worked!

So basically here's a list of what I've ALREADY tried with no success:

1. Full cycle charge (drain to nothing and charge to 100%)
---a. From cable to computer
---b. From cable to outlet
2. Restore from backup and re-jailbreak+unlock in iOS 4
3. Restore from backup and re-jailbreak+unlock in iOS 4.0.1
4. Restore as new phone and re-jailbreak+unlock in iOS 4
5. Restore as new phone and re-jailbreak+unlock in iOS 4.0.1
6. Removed Activator, Libhide, PreferenceLoader, and anything SBSettings related
7. Disabled 3G(I only have EDGE), disabled Wifi, disabled Push, disabled Bluetooth
8. Not leave anything in the multi-tasking menu (although I don't even think this would affect it)
9. Low brightness
10. Reseat the SIM
11. Coat the SIM edge with nail polish to prevent the metallic coat from grounding the tray
12. Go insane >=|


Is there anyone out there who can help me?.. Please? I love this phone but I don't like AT&T... =(
 
of course you had better battery usage before if you only used it as an iPod touch, turning on 3G or EDGE for calls and web browsing (plus push notifications and push emails) will decrease the battery more.

I left the phone on standby with no browsing and no push/notifications on but it still lost 5% per hour. Is this normal?

It's the unlock. Restore as new and rejailbreak to get rid of the unlock and the battery drain problems.

Oh man... I need the unlock to use T-Mobile, though! So should I restore as new again and rejailbreak again and wait for a better unlock to be released? Because I think only the team behind ultrasn0w is currently active.

2 things.
One Jailbreaking shortens the battery life somewhat due to the tasks it does in the background
2. Turning on cell data is a battery killer.

Thanks. The jailbreak I tried to remove everything not necessary already but I guess there are other things running I don't know of. However, for cell data I only use EDGE so I never have 3G on. Is that still a battery drainer? Because I'm getting longer battery life on my old 2g phone than this one.

The word your looking for is "lurking"

Thanks, haha. I knew that word but for some reason I couldn't think of it through all my anger and frustration.

I really believe the issue is the unlock far above and beyond everything else.

I use everything that the OP and others listed and have excellent battery life. The day I unlocked, I lost 10% in 4 hours of standby, which is terrible. As soon as I removed the unlock, my battery life returned to normal.

Push data only affects my battery life harshly when I'm jailbroken. I don't know what it is, but just try it and let us know your results.

Ah, in the case that you need the unlock, you are just going to have to put up with significantly reduced battery life (or an iPod Touch iPhone 4 with no calling/cell data). There should be some battery cases out in the next few months, which could help to alleviate the problem, protect the phone, and mitigate the antenna defect.

Yeah I have a strong feeling it's the unlock as well. I just think it's slightly ridiculous that my old jailbroken+unlocked iPhone 2g has better battery life with many processes on vs. the iPhone 4 jailbroken+unlocked with most processes off.
