Battery drainage

Does replacing the radio with the one
everyone is talking about fix the battery
drain problem? I replaced my battery less
than a year ago (unaware of this issue) the
last two weeks I have had to be jumped off
almost everyday and battery is testing fine.
My radio works but the cd changer, aux,
Bluetooth, etc do not work. I've never
looked for solutions because I don't use
any of those things anyway. However if
replacing the radio will fix the battery issue,
I'm gonna order one today!
