Why do batteries on Mac computers last much longer than all others?
batteries May 4th, 2009I've never seen a laptop that can hold a charge for more than 2 hours. Mac users tell me their lap top batteries go on all day on 1 charge.
Apple has rules for programming that release unnecessary information and processes instead of holding them. At least this is true for the iPhone, which is programmed in a light version of the framework used by OSx. This allows the software to run more efficiently and has something to do with battery life. There are of course other factors, but this is one thing.

I don't know why either but I would suggest that as long as you keep your laptop plugged in when it is near a power plug then plug it in. Always try to keep it plugged in wherever possible. I think it might be that the PC's just get too hot and it is trying to work extra hard to keep it cool inside so it pushes the fan to a more higher rate.

They are either lying or not really using their laptops during that time. Other laptops can keep their charge on idle all day too. Mac batteries are okay but they are not top of the line out there.
The new 17" MacBook Pro however does claim something like a 7-8 hour life under actual usage. I've heard it can actually meet those claims as well. But that is just the 1 model. The other models don't have that battery type and so are more in the 3-4 hour range.

It really depends on the amount of power a laptops is using, what power options are set, and how many cells are in the battery.
Most mac laptops I have seen last about 3 or 4, although the new macbook pro models can last like 8 hours on decent settings. I have also seem some Samsung netbook models that can last 12 or 13 hours.

I wouldn't say they can go all day on a charge. I have a previous generation MacBook Pro and the most I can get is 3.5 hours. The biggest difference I've seen is in the power management of the operating system. When I'm running Windows XP on my mac, I normally can get only 1.5 hours compared to the 3.5 of Leopard. Different software writers handle battery usage in different ways, some better than others. If you're under Windows or Mac, exiting programs that you don't need open can help a lot with battery life. Every time a program uses the processor it sucks just a little bit more power from the batteries.

Because unlike a pc, a mac battery cannot be taken out. Because of this, precious space inside the computer is not being taken up by a mechanism that removes the battery. With the mechanism gone, the battery can be 40% bigger, thus a longer battery life.

Except for new 17" Macbook Pro, Mac computers has just an average battery life - 2-4 hours, depending on a model.
