I am a pretty light user and know all the battery saving tricks and my phone usually lasts for 2-3 days on a charge, but right now I am not even getting 1 day out of it. This started all of a sudden and I didn't change anything myself. Due to past phantom power problems, I happened to have a battery logger running at the time and I can see that in the morning a few days ago, around 3am the idle current went from 6mA (normal at night) to 45mA and never went back down. However, none of my apps seemed to be doing anything strange. There are no periods of extended awake time or anything either. I installed the Gsam battery statistics app and it was telling me that the "phone radio" was sucking down a vast majority of the battery. But it also says that I am in good signal ranges, 3+ bars almost all the time (I am in the same areas I am always in). The "cell standby" in the phone's battery manager menu (which is probably the same statistic) is also much higher than normal. Has anyone else seen or solved this issue? What else can I do or check to figure out what is going on?
