Question about MacBook Pro

[AppleTecFan]

I just switched to mac and I love it

I got my MacBook Pro just a 4 weeks ago and when I fully charge my macbook it saids only 5 hours and 25 mins. left why is that??

It probably depends on what you are currently doing. I think laptops try to estimate how much time you have left if you continued to do what you are doing. If you change some settings, close some windows, this time might change!

I think at least....

It could also be because of your Power Settings.

If yo go to Settings and go to Energy Saver, you can play around with some settings.

The computer might detect the change and also increase or decrease the time?

Have you done a calibration cycle?

If not, or you don't know what I'm talking about, do a forum search for 'battery'.

As others have posted the computer guesses at your battery level. By calibrating it, you help the computer refine that estimate. While apple recommends a more frequent cycle of battery calibrations I'd say that its not worth it and deep draining your battery does more harm then good imho

I would recommend doing a battery calibration.

Also, as previously mentioned, the time displayed will constantly adjust based on what you are doing at any given time.
