So apple replace my replacement battery from the recalls since i was only getting 50% health out of 65 cycles. So this is basically the third battery for my 1st gen mbp. right now it is at 99% health and 6 cycles but i am only getting maybe 2 hrs out of this thing. i've tried all the resets and calibrations and still the same. at first i thought it might have just been me using it intensively but even on firefox i only get 2hrs. i've heard people talking about leopard killing their battery life when they switch over from tiger. the only thing i notice that was odd was that when it was charging, leopard would show me that its gonna take 1hr 40mins to charge to full from empty, but i would check istat pro and it shows me like 2hrs 50mins or something higher. i thought it might have been the magsafe but that was replaced also. i still have 90 day warranty on the battery so i can return it if i have to. my mbp is out of warranty so i cant really do anything about that. anyone have any suggestions or idea about this battery issue, pls let me know.
