I have iphone 4 16 gb on 4.3.3 + redsnow 17 jailbreak. Its drain 15% per night (7 hrs) with all internet options off such like edge, wi-fi, 3g. Push is disabled, no apps in background. I tried to restored it like new under DFU - no effect, i tried to roll to 4.2.1 and 4.1 - no effect. I disabled Ping and other option - no effect. I even change my battery to a new one and guess what - no effect. Its drain battery the same way with airplain mode. So please help me.
