Lion - Horrible MacBook Pro Battery Life

Ditto

my lap top is up to date

same problem

Hi again. I bought a new battery and have reverted to SL. Still have battery times which are not very good. 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.

13" MAc Book Pro

Version 10.7.3

May 2011 model.

2.7 GHz Intel Core i7

*GB1333 MHz DDR3

Same problem, noticable battery shortage with Lion.

That's great, CT, except that my MBP has had this problem since I took it out of its box in November, which makes it a bit tough to pin the problem on anything I have or haven't done with it.

Mac 101

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 ...

A few studies show that it isn't Lion itself that kills the battery. 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.

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

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!!!!

Thanks. I read it and I guess I didn't let it rest for 5 hours. I will give it a try today and see what happens.

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!
