Remove Ultrasnow, and everything will be back to normal. we already tested it, and the Ultrasnow is the cause of the problem

unjailbroken percentage drop over 1 hour with wifi on 0%
JB with no JB apps except Cydia over 30 mins 6%
Something not right here......

if ultrasnow is to blame maybe part of the problem is the carrier you are using after unlock. could diffent carriers have different power requirements to obtain signal from the carrier?
has any one tested with iphone jbed and unlocked but without sim(different carrier sim?), if you are saying that battery drains even without use?
couldnt this be true especially between different countries?

I actually tested that. I took my SIM out but still left ultrasn0w on, and it was still draining 3-5% on standby

HAve the same problem. I made a JB (by comex) for my Iphone 4 and unlocked it by ultrasn0w (since I have to use it outside of US). I'm losing about 3% per hour staying in Airplane Mode! All known battery draining processes (wi-fi,push, multitask, locator) are off. Also APN setting have disappeared from the Network Menu.
My previous iPhone 2G loosing almost nothing while in Airplane Mode.
Does anyone know what COMEX and ultrasn0w's author say about this problem? I'm desperate about this, since otherwise I'll get $653 iPod.
Please help! Thank's in advance

Planetbeing and Musclenerd have been MIA from twitter for the last 2 or 3 days after all the tweets they're getting, so either they are just enjoying their weekend or they are actually hard at work for the community. Comex is responsible for the jailbreak so I don't know if he would know anything about the unlock.

Maybe it's not a bug at all lol, have you guys tried restoring it as a new phone and then jailbreaking and unlocking? Idk give it a shot?

I have restored like 3 or 4 times today alone and if I set up the phone as new I loose around 1-2% hour on standby with (3G off, WiFi on, location on, push notifications and emails on) then I apply JB and NOTHING else and I loose around 10-12% per hour under the same conditions.
I notice the battery drain is not as bad when 3G is on (and WiFi off)
I have a factory unlocked iP4 so i havent tested ultrasn0w. But this def is an issue even without ultrasn0w

SorryI should have said my battery isn't full when doing these test, i kept it around the 60% level (for not particular reason, just restoring, unplugging and seeing the result). I am not sure how linear the drain of the battery is.
The point i guess is that all thing equal, the JB alone seems to 5x the battery drain on the phone

I wonder if Apple anticipated the loophole for this jailbreak and put in some code that would deplete the battery faster if jailbreak was to be used...

haha...that would suckk......ok guys...I uninstalled ultrasn0w...and I manually download the mobilesubstrate and unlock .deb files....and transfered them via SSH...it worked...so now im just charging it to 100...then seeing if it makes a difference....will post download links to the files if it works.
