How Many Cycles Does a MacBook Battery Last

This has been happening since the 10.6.8 update hit or longer (didn't notice prior to that) so restarting isn't going to help. Also, in my post I already stated that I had calibrated my battery. I did so two days ago.

Oh ok; hey I'm right here with you. Before .8 my Blackbook reported a little over 4 hours when I had nothing running. Up until yesterday, for the past few days it read a steady 2.x hours no matter what I did. In reality it just stayed around the 2 hour mark until it actually had less life.

Here's to hoping it gets fixed soon, and the problem gets solved for you as well.

You could also calibrate the battery and see what happens then.

Launch Activity Monitor and change "My Processes" at the top to "All Processes". Then look to see what may be consuming system resources. I don't know if you use Parallels or not, so this may or may not apply:
KB Parallels: Mac Dock consuming 100% of CPU core after upgrade to Mac OS X 10.6.8
 
THANK YOU! It was indeed Parallels showing the Windows application folder in my Dock that was creating the problem. Man, I'm so glad someone found a fix!

Unplugged my charger right after removing it and my battery status jumped from 2:00 to 5:20.

What an obscure bug.
 
Wow, I am really confused now.

I downloaded Coconut and ran it. My battery shows 117 cycles and 101%. However, in the past month I am only getting about 1 hour of battery usage with WiFi and Bluetooth turned off. I am not sure what is draining it so quickly that it is doing this. I have calibrated it twice recently trying to fix it with no success.

Other than replacing a battery, any ideas? I would hate to buy a new battery just to find out it is doing the same thing--because I have a hardware issue.

Thanks.

It is a 13in MacBook running 10.6.8...until Lion comes out, that is.:)
 
Late 2008 Macbook Unibody (bought upon introduction)

662 cycles
Health: 87%
 
I have an early 2011 mbp 13 inch and only 59 cycles but a health of 96% its strange cuz my old Macbook 4.1 had 800cycles and still 99% :/. When is the point when it makes sense to take it into a store? 50% health at 200cycles?

96% after 35 cycles?

how do i improve/maintain the life of the battery?

Let the battery run down ones a month til your computer goes to sleep and than recharge it to 100%. Thats my top tip cuz according to Apple these models already have a calibrated battery so you can't really do anything:


Additional Information
Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure outlined in this article. These computers use batteries that should be replaced only by an Apple Authorized Service Provider.

maybe i'm letting mine die too often then, or letting it get to 9% too often.
i just sit here and leave it, and when i see the message, then put it on full charge.

As has already been stated many times in this and other threads, your battery health will fluctuate up and down over time. It's perfectly normal. Also as has been stated many times in this and other threads, this should answer most, if not all, of your battery questions:

System profiler says I should replace it soon though...

is over-calibration is harmful?

When my battery dies, I plug it in and charge it, use it until the battery dies, and this process goes on forever.....

is this considered "calibrating" my battery? If so, is this bad since I run out of battery every day or two; hence, im calibrating my battery every other day instead of once a month?

Apple says calibrating your battery requires you to leave it without power for 5 hours. Does this mean what I am doing is not harmful to my battery?

I would like the answer to this as well, I skimmed through the next couple of pages (it was asked on page one) but didn't see anyone answer.
