Fixing Snow Leopard Unibody MacBook Pro Battery Life Problems

mac-batteryEver since I upgraded the OS of my Early 2009 13″ MBP to Snow Leopard, I have a problem with the notebook’s battery life. When I was using Leopard, the battery could last very long, so long that I was used to working without connecting the notebook with a power source. I also remember that the Time indicator for the battery used to estimate about 7 hours or so of battery life at 100%, although it occasionally fell to 3 or 4 hours on heavy usage. But now, at 100% it would only show about 5 hours max.

For some time I used to think that this was probably due to 64-bit architecture change that caused the notebook to use more power. But the longer I used the notebook in this condition, the more I worry about the battery. According to Apple, the new battery technology in unibody Macs are supposed to last for 1000 charge cycles, about 3 years of normal usage. The battery problem means that I am using more cycles than it is supposed to be for a given time, which increases the possibility of the battery having degraded performance before the 3-years mark.

So I googled around a bit, and found out that other people are also experiencing the same problem. The solution to this problem is to do the following :

  1. Reset the PRAM.
  2. Reset the SMC.
  3. Recalibrate the battery.

I did all three and the problem is now fixed, I can now see the 6+ hours battery life indicator on 99% again :).

~7 hrs on 99%


EDIT : I am conducting a battery test to see the actual performance of the MBP’s battery here.


My Apple Experience

I have recently switched to using an Apple MacBook Pro as my main means of computing. This is my impression of owning an Apple product so far.

My Background

I had never been a fan of Apple product. Although I really liked the nice interface, I don’t like Apple products for several reasons. Firstly, it’s expensive, Apple products are known for their high price. Secondly, I can’t use it for work, I am a software developer who writes mostly for Windows. Third, I can’t use it for serious gaming. Fourth, Apple fans/product owners have this particular attitude that I don’t really like much. Apple seems like some kind of religion for some people.

Although I was not a fan of Apple, I admitted that Apple makes high quality products. And I even recommended buying Apple to some of my family where it was relevant for them.

When Apple recently introduced the 13-inch MacBook Pro to its product line while also lowering the price, and also being encouraged by a post by a fellow developer, I thought that it was probably the best time to try to own an Apple product. Nowadays Macs can run Windows through Boot Camp anyway. So I went ahead, I sold my relatively new ASUS laptop for a MacBook Pro.

Batik Day!

Yesterday was Batik Day in Indonesia, a day where Indonesians are encouraged to use their UNESCO approved world heritage, the Batik. So we at the office wore Batik and took a photo.

Guys at the Office

I think in the future we will wear them to work more often.
