Any other iPhone 4 owners experience the same? Previous to the update, overnight the phone would drop 4-5% (over 8 hours). Now it drops about 15%, which is a pretty significant difference. I do have some Cydia apps installed but they were also installed when I was running 5.0.1 so I don't think they're the culprits. Other than that, I tend to keep the background processes clean and have never used any push features for any app. It's unfortunate because I used to be able to get about 24 hours of use out of a single charge and now seems like I have to charge at least a couple times a day.
