After the jailbreak using redsn0w and installed 2 apps(backgrounder and acrobits) my iPhone 3gs, BB 05.16.02 has only about one and a half hours of battery life. Before the jailbreak, one recharge is good for about 2 days. The only apps running in the background is the soft phone from acrobits. Is this normal for this apps to drain the battery this fast? Or may be I have turned on some of its capabilities that should be off if not used? After all the tweaking and trial and error configurations, I can't really exactly remember which part I have tweaked hehehehe.... As of now, the only intended use of the iPhone is to use wifi for soft phone and for internet. Please advise.
