hey guys, ive been a happy 4S user from day one and have never had bad battery life like some people have been plagued with but out of nowhere for the last couple of days battery life has been shocking!!! it goes down about 15% an hour....on standby! the only thing ive installed on it within the last couple of days jailbreak wise has been the critical cydia update and ive removed nearly everything else to see if an update that im forgetting about has led to it but nothing has so far solved it. one thing i have noticed is that even when there are no apps in the switcher i only have about 150mb free RAM where i used to have about 270 so something is definitely running as the phone is constantly warm. is there any cydia app or something to tell what exactly is being used for RAM and CPU usage etc??? apps ive tried have only told me how much is being used and if the ram is active, free etc but not what is using it. any help guys??? thanks.
