Anybody having problems with Nokia 6136. This a BT Fusion upgrade phone. I've had BT Fusion for 12 months and been fairly pleased. The Nokia upgrade phone dischrged completely after six hours, then 3 hour and falling. BT replaced it and the same is happening again. Obviously this will be replaced - but I use the phone very little at the moment. Is this a phone fault, battery fault or BT Fusion. Anyone else had this experience?
