Q: Lion - Horrible MacBook Pro Battery Life

Mar 11, 2012 3:17 AMby yvell,Also, the EFI update improved things for a few days = or maybe be not even that (I even took screenshots, the first time I used my Macbook after the update it lasted for around 6 hours), but after that, just the same old story, everything is exactly the same, don't even know why I bothered updating it.

Any comments on the screen dump below which was taken doing somre regular surfing wilst listening to music streamed to an apple tv 2 4:47 @ 96 isn't very strong when u have the screen at 50 % is it?? I have a 13 inch MBP 5.5.

Mar 12, 2012 5:58 AMby Goatstorm,Well, thanks for that very helpful link. But it seems they forgot the most important hint how to get a good battery life: "Don't install Lion!"
So frustrating, still no improvement whatsoever. Out of the six people I know who are using a Macbook Pro (including myself), five are having serious troubles with battery life after installing Lion.
And still no Cloud support for Snow Leopard ...

My batter was originally lasting 6+ hours on medium use (wifi, itunes) and after installing lion it dropped overtime down to as low as 3 hours. However, Activity Monitor is lions way of keeping things in hibernation mode incase they are reopened for your convenience. This pretty much leaves the program running. After disabling most of the applications off there my battery jumped roughly 3 times higher. So far this fixed my issue though will see what happens.

Mar 13, 2012 4:24 PMby Olympus,Mine is the same. But mine started at 10.7.3... As of yesterday, I was down to 45 min. But, my battery had been on it's 800 cycle... but the kick is, I had ordered a new battery and it came last night. I installed it and let it trickle charge all night. Now I get a whole whopping 1:30 of use!!!! This is total crap! I hope they fix this soon. I do lots of consulting and meet clients everywhere.

You have no idea what you have, other than uncalibrated meter and a duty cycle waiting to be run. It is an estimate, and it is an estimate based on the performance of an 800 cycle battery. Calibrate your Mac for the new battery, then use it normally

Mar 13, 2012 4:48 PMby Olympus,If I'm not mistaken, my late 2009 MBP battery comes calibrated. However, I think that setting calibration is going from 100% to sleep sets that. In that case, I calibrate everyday!!! When the dialog pops up saying I am on reserve now, is when I plug it in. And this morning, 1 hour 20 min. with a new battery!!!!

You said
"I had ordered a new battery and it came last night. I installed it and let it trickle charge all night. Now I get a whole whopping 1:30 of use!!!!"
So please, which is it, a mid 2009 800 cycle + battery, or the new one, the one that your Mac did not come pre-calibrated for!
