Q: Lion - Horrible MacBook Pro Battery Life

i followed all the instructions here... and now i have 9 hours back on my MBP Early 2011.... first i downgrade to Snow Leopard, then i install every update, then y upgrade to Lion OS and also install the Developer's Delta Update 10.7.2 and i also install gfxCardStatus and set it to use only Integrated... and Restart the SMC i don't know what did it... but my battery is working better now!!!

I followed all discussion I found by googling.

I have done resetting SMC, calibrating and install gfxCardStatus (which not working for my MBP)

All don't work.

What I found working is doing a Disk Repair.

There a a lot of error.

And it seems working now....

MacBook Pro

13-inch, Mid 2010

Processor  2.4 GHz Intel Core 2 Duo

Software  Mac OS X Lion 10.7 (11A511)

Lex,

I do aware of that. It might be just a coincident that my baby's batt suddenly show its symthom right after I upgrade to Lion. BUT as of now, I'm completely unplug, Lion said 5 min ago that it is ~30 min. left, then I walk aware a bit and it go to sleep, now I'm coming back it said 1 hr 9 min left, mean while I'm typing this msg at 31% batt with Lion calculate 47 min left. It kinda odd.

It said service battery (right after upgrade too), so now my System Info. state "Condition=Service Battery" Indeed, I plan to get a new one on the way now, will see what Lion effect to the brand new batt.

I don't know what went wrong with you there. Maybe it was because you didn't use a regular USB. However, please see this page: http://tonymacx86.blogspot.com/2010/04/iboot-multibeast-install-mac-os-x-on.html

this is what I used when I installed SL on my PC. Use you disk utility to create a USB from your SL. Then choose the boot disk from USB and try again. Good luck

Hi,

Thanks for the reply. However, I'm on a MacBook Pro. To remove an extra graphics card and the extra ram is something I don't want to do (whether it would work or not on a laptop is another question). These new units are all sealed back there without the batter access door.

Overall, I'm just surprised that Apple would do this. I mean, I bought this laptop, not for Lion, but for the processing capabilities. But I can't use half of my software, and of course, the battery life is dreadful. The good news is that I can still return this machine for a full refund, including the replacement they're sending. Perhaps that will send a small message. Very small.

Where did you get a hold of 10.7.2?  That maybe the solution for us.  I hope Apple releases that already.

hi chokung, your battery may still keep going for a while, but not for years...

the behaviour you have mentioned is that the battery to MBP communication is "off". Perhaps you should do a SMC reset again:

shutdown the MBP,

connect the charger,

when it charges hold down at the same time the following FOUR keys (on the MBP built-in keyboard !) Shift- Alt-CMD-on/offbutton  for several seconds,

then let them go at the same time,

wait a few seconds,

then restart the MBP, after a day or so the battery info behaviour should be "normal" again.

Oops, should be Shift-Alt-CTL-on/offbutton.

jess, this is for developers only. beta. but I guess the update will come soon for all of us.

I decided to follow all advice. I got 3 hours from my new MBP bought 29/07/11. Apple deny it is Lion. I am having a new one sent to me as I only have 98% battery left in under 2 weeks. Faulty battery. Will see when new one comes

13' base model 2011 air

i'm wondering about the battery as well

some data during a day with coconutbattery:

and i noticed that running only safari when i scroll up/down the page with 2 finger the cpu in istat jumps from 3% to 33-39%

this is what happens when i leave it over night whith closed lid:

i doubt it will last 30 days!!!

the first data list of coconut on one day is nothing wrong with: the accuracy above 95% is several %.

My 2009 MBP is doing it from day one and I am still at 97% of capacity (plus or minus one or two percent).

The difference overnight is not normal: something is running... Is it searching for WiFi or something else is running.

Well, add me to the list. I did a clean install of Lion on my mid 2010 MacBook Pro. Now my battery, which would usually last 4-5 hours with typical work, is dead inside of 2 hours. Heck, in the last 10 minutes alone, doing nothing more than reading this forum, I've watched the charge go from 92% to 85%. The battery is in great shape, and was well maintained with a full cycling performed every 6-8 weeks.

It's unquesitonably Lion and we can only hope 10.7.1 will fix the issue.

Well, same with me. In fact, don't rely on what system said much because there is definitely something WRONG with Lion.

My case, MBP2.2: On the beginning of today evening computer; @98% it said 1.11 hr left well, after browsing, video, flash a little 30 min now @62% and 1.19 hrs left, WTH come on launch the patch&update.

Lex,

I should run it until the battery drain right?

Thanks a bunchhh, will do tonight.

Guys,

I repaired the permission on my MBP and I got 1 hour battery more.. Now I have the same battery life of SL..

Hope this helps
