BB Bold :: No Reception When 9650 Plugged In

Every time I charge my Bold (9650) I loose 2 bars of reception, this is not good due to the fact I only get 2 bars of reception in my house, my job requires me to be 'on call' and many times I haven't been notified of a situation that I need to address due to the fact I have lost reception- it will have low reception initially after it is plugged in but after an hour or 2 it looses reception completely- after I unplug the phone I immediately gain 2 bars of reception- also many times when I am texting the phone will freeze for approx 20 seconds - to the point of throwing the freaking phone against the wall (durable phone though).
