Query: Get BL-6C instead

I bought this as a replacement battery for my Nokia N-Gage QD about 3 months ago. I've had my n-gage for about 2 years now, and thought it was time to get a replacement battery. The vendor sent the battery in a timely fashion, and I have no complaint about them. However, the battery only has a standby time of less than 2 days. When I recharged my old battery that came with the N-Gage (BL-6C), it had a much longer standby time. The BL-6C is rated at 1070 mAH. I guess a difference of 250 mAH between the BL-5C and the 6C really makes a huge difference. I still use both batteries, and alternate after about a week or 2, so the other battery has a chance to discharge. In retrospect, I think the older battery is performing much better now that it has a chance to discharge from time to time. Check the model of the battery that came with the original phone, and go for the same model. If it were between the 5C and the 6C, I highly recommend the 6C. Don't get the BL-5C. Good luck.
