i jailbreaked my iphone 4 4.2.1

i notice less battery life with jailbreak. is this normal?
 
unfortunately i don't have =/

Well if you just jailbroke your device, using apps like Cydia to search and download tweaks will cause your battery to drop (only while using it). I would recommend charging your phone to 100% and just use it normally as you would if it was not jailbroken. There shouldn't be a decrease in your battery life with just those two things installed. I have a lot more installed and my battery seems to be just fine.
 
Try a reboot. Try a restore from backup. Once you do figure out the culprit, try and keep your tweeks to just 5 or (at most) 10 if you are trying to have comparable battery life. I just have sbsettings, bitesms, my3g, infinifolders, and activator. I don't see any difference in battery life.

I didnt notice a difference whatsoever when i jailbroke my iphone 4 4.01 with jailbreakme.

The only thing that interests me in jailbreaking is tethering. so all i installed was MyWi. And terminal to change root pass.
 
I have had jailbroken iPhones since generation 1 and have not noticed any significant battery draining. I would check again to see what you're running that's sucking up up battery.

Since you always JB the iphone and dont use it w/o it, you dont know the diference.

Actually yes, JB 4.2+ (not sure about 4.1) drain the battery, how much, like 15-20% more,

Today I did the JB for 4.3.1, since 4.2 im not using JB on my iphone coz the battery drain.

Daily I do the samething, Drive to the Gym (~15 mins), at the gym while im in the bike watch a series episode (~40 mins), do some workout listening music(~30 mins), drive back to home (~20 mins), by the time im back @ home my battery is @80-85%

Today, back to home, using my iphone 4 4.3.1 w/ JB, the battery was @ 68%.

If you dont care about that draining, its ok, but sadly it matters for me.
