I have always had perceived battery issues with my MacBook Pro 15 (mid-2010) compared to the advertised life. Never more than 3.5-4 hours.
However, I recently followed the instructions on Apple page for "Resetting the System Management Controller (SMC)". Follow them exactly- suggested rest times after charge, 5 hour wait time while discharged, etc,. etc.
However, upon doing this the battery life shortened even further immediately. Now I'm getting 2.75 hours at best. Now, logically I don't think this is a battery cell thing else I would have been getting 45min-1hr more time just before doing the reset and previous 2 years.
So... I did the full SMC reset again just to make sure. Nothing. Still getting drainage on the clock from the beginning. 100% to 96% withing 2-3 minutes. Down to red 13% withing 2 hours. No flash video watching. Just the same MO of usage and activity I did before the reset where I got better battery life (but thought was poor).
Question1: what gives?
Q2: anything to do now to really fix it - at least back to life I had yesterday and before?
Q3: dont want to shell out $175 for anoth battery right now but this is ridiculous. <3 hours is almost not usable when in the field. And the 4hrs I only ever got before is still WAY BELOW the original advertised life of 8-9+hours Will putting in a new battery even make things better than 4 hours?
Q4: was my regular usage on the AC adapter to possibly blame for the poor life out of the box?
