I originally thought it was either infindock or overflow. Which I was partially right. Overflow eats battery bad, but I uninstalled everything from cydia and while the battery life is better, its still not on par with non jailbreak.
Is this normal?
JB an iphone does nothing more than add a second app store icon, (cydia) to your springboard.
Adding that extra icon does NOT cause any extra battery drain.
Apps/Packages downloaded, installed, and running on your iphone can and will drain your battery faster,
(but adding the extra icon by JB does NOT).
I wish someone would make that a *sticky*, (this should be common knowledge by now).
