I have had my macbook for about 3 weeks now, I admit I have not used it in a continual long stretch at all yet but it has been charged at least 10x by now. I charged it up last night to 100% and set about using it today. I got just over 1hr 50mins of use before the reserve power message. I literally did nothing but chat with one person on gchat wirelessly for the 1hr 50min or so. I did not surf any webpages or anything intensive.
To me that battery life seems pretty poor....anything I can do about it? Its frustrating that it takes longer to charge than discharge...
-
Did you have the back lite on full? That will kill the battery. Did you calibrate it?
-
Back light on about 75%, not calibrated no...the battery you mean?
-
Have you set the power management to 'better battery'?
-
Download iStat and check your battery health.and yes,he meant battery.
-
Where is power management in the OS? All I see is energy saver preferences, which does not let me select something as in Windows Power Management.
-
Right top corner, click on the battery sign.
-
well yeah, I have done that....that is "energy saver"....I dont see anything about setting it to "better battery" though...
-
oh well I mixed up some terms. "energy saver" is the one.
you can set some preferences in the system preferences panel. -
1 hour 50 min does seem a little low, but still believable. I think the main issue is with the screen which draws the most power. If you lower your brightness, you should see a significant change.
-
Regardless of screen brightness, , sub 2 hrs is way too low
either the battery has an issue (easily checked through istatpro or system probiler> Power)
or there is a rogue process keeping your CPU taxed continously (again easily checked via istatpro or activity monitor..) You CPU usage should hover between 1-10% when the system is idle
Aluminum macbook battery?
