Mid-2009 MBP 13" Battery Life

Is 3-4 hours normal for my 13" 2009 MBP? I used to get ~7 hours with Leopard, it dropped slightly with Snow Leopard, now with Lion, I only get 3-4 hours.

In system information, it says the following for "Power":
Charge Information:
Charge Remaining (mAh): 2873
Fully Charged: No
Charging: No
Full Charge Capacity (mAh): 4954
Health Information:
Cycle Count: 348
Condition: Normal
Battery Installed: Yes
Amperage (mA): -894
Voltage (mV): 11301

Is this normal?

(I've already done the SMC reset.)

My 2010 13 inch has around the same amount of cycles but it may be possible that your battery is going dead. You could partition the drive with leopard or snow leopard on it to see if your battery life is any longer with them still.

That's a really good idea. I can't believe I didn't think of that...
