Battery Life Already short?

[gadgetgirl85]

I've had my MBP CD since about August and keep it plugged in nearly at all times except when I go to university. I calibrate once a month and now my battery is barely lasting 2 hours. Is that normal?

What do you mean by you calibrate the battery once a month, I have never heard of this being done?

Depends on how how you are using it

Wireless, Brightness, are the big drains.

it is healthy for the battery to cycle (use it to almost empty) a few times a month. I'm on cycle 16 since November. today i got about 3 and a half to 4 hours, with brightness at 3, bluetooth off.
