[QUOTE="coolbreeze, post: 886697, member: 53200"] Ok I just ran the test again. - Better Battery life selected - brightness slider was placed exactly halfway - bluetooth was off - illuminated keyboard backlighting was off - spent the whole 30 minutes surfing around MacForums only - Time Machine was off (was off during the 1st test) - No peripherals attached (none were attached during 1st test) - my machine is new, purchased in June 2009 (I opted not to buy June 2009 model), therefore my battery still should have original capacity I started at 9:25 with 100% charge and at 9:55 I had lost exactly 10% charge, down to 90%. It was exact. This means I lost 1% charge every 3 minutes compared to loosing 1% charge every 2 minutes in the first test. In the first test I would have lost all charge in 200 minutes (3 hours and 20 minutes). In the second test I would loose all charge in 300 minutes (exactly 5 hours). I did not make these numbers up nor did I round. They just came out exact. When I purchased this notebook the salesman did say my battery would last 5 hours without charging. He didn't say you would have to be doing very little to achieve the 5 hours with no charge. Anyway, I'm satisfied. I was only curious. Anyone with an irremovable battery experiencing battery power without charge for 7 hours as advertised? [/QUOTE]
