Hi, I'm pretty happy on my jailbreak currently, but really only use it for no ads on pandora and tethering in an emergency. The problem is my battery is pretty inconsistent. I'm noticing the phone is dying with anywhere from 2-7% left. I let it full charge and same thing the next day. Another issue I'm having is the power button has become janky as well. You have to hit it just right for it to work. I have 2 months left on the warranty and really am considering if this is a big deal or not. I don't want to lose my jb, but I'm also curious to try 7.0. But also I don't want the battery to continue to degrade. Although not terrible, I use to ride this phone for like 10 mins on 1% before it died. Thoughts?
