Battery monitor keeps fluctuating

[baldabiou]

Hi forum!

I got myself a Macbook a couple of days ago. It's also the first Mac I've ever used, so I'm not fully acquainted with all the OS characteristics.

In particular I'm puzzled as far as the battery monitor is concerned: the time it shows keeps on fluctuating: as I'm speaking it first shows 3:02, then 3:11, then 2:52, then again 3:00, then 2:43 and then again 3:02 (all these values in less than, say, 5 minutes).

My question is... is this a normal behaviour or should I worry?

Thank you in advance to you all

No worries. Depending on your CPU usage/screen brightness/network traffic/applications running, your time will fluctuate like that. You don't have anything to worry about. Enjoy your MB

Hi VSMacOne!

I thought I replied.. And I didn't!
Well, thank you for your answer!
Now that I've got a bit more acquainted, fluctuations seem reasonable!

Yeah. The computer calculates the time by what's going on right then. When things change (CPU, apps open, backlight), the time is recalculated to adjust to the new attributes.
