Hi I have a few qs about the battery. 13" 2010 model please dont tell me to read that battery article - I read it 10 times already. 1- I am getting shown 3:40 left with Brightness 100%, Keylights 100%, 1 USB modem plugged in sucking 5W. Only safari open. is this acceptable? battery usage between 14 and 20W.. isnt that high for only safari and 1 usb device? 2- My battery life was 96% from the day I got it, until a month ago. A week ago I noticed it went down to 89%. Yesterday I calibrated, and now its 91%. I know this is not extremely accurate, but is there anyway to set it to the real level? a- I recalibrated yesterday b- MBP was bought on Jan 28 2010 Brand New - NOT refurbished from apple. for some reason Coconut battery says that the computer is 7 months old. is this a problem?
