It has been observed as of late that the Macbook or the Macbook pro users who have purchased their devices in 2006 or 2007 are losing out on battery life of their devices at an alarming rate. This problem is not being face by one or two user alone, but there are a huge number of users facing trouble with their battery life. Apple has had a very large batch of Sony lithium-ion polymer batteries for their laptops that are losing their maximum charge capacity very quickly.
The battery that is normally accompanied by the Macbook or the Macbook pro is to provide a backup time of 4 hours. Now, if you are one of those users who have recently noticed that their 4 hour battery life is dropping to just two hours or so, then there are some things possible for you to do in this respect. You can check your System Profiler for some information about your laptop battery power system. The System Profile is to be found in Finder => Applications => Utilities => System Profiler.
When you shall have the System Profiler open, then you can find Power underneath Hardware. This item needs to be clicked on, and then you need to scroll down on the right side of the window. You are required to scroll down till the point you find the heading Battery Information. There are only three values one is interested in, and they are Full charge capacity (mAh), Cycle count, and Battery health. Now you need to check the values in these sections.
For a full charge capacity, a normal reading is to measure about 5200-5400 mAh (milliamp hours). This actually translates to just a battery life of over 4 hours. The term Cycle count refers to the number of times the battery has been used to capacity, and then recharged. The term Battery Health is used to refer to the overall life expectancy and condition of the battery. One interesting fact is to be kept in mind that the company Apple has published on its Apple support site that their laptop batteries are designed to hold 80% of its original charge capacity after 300 cycles.
Thus, according to the calculations, the Full charge capacity should be around 4160 to 4320 mAh after 300 cycles. But, there seem reasons for you not to worry. The company provides quite good customer service. You can bring your Macbook to an authorized service center, an Apple flagship store, or you can even call up Apple support hotline and explain the situation. Also you can note that for those of you using the Macbook and experiencing the battery life problems which have been discussed as above, the warranty coverage for the same is being extended to two years. Thus, looking at the brighter side of things, the battery of your Macbook shall still be in warranty even if your Macbook is not in warranty. So, go ahead and enjoy quality service now.
