Macbook air , Sudden 4% Battery drop down !
I have recently bought my macbook air 13" 256GB from canada apple store ,I have full charged it 2 times in 100% , and both times after i unplugged my macbook from the power ,the buttery sudden dropped from 100% to 96% in a second!!!!
whats the problem? is that normal ? this is my first Mac ! I have confiused
please let me know if this is a problem , i will go to app store and ask for exchange !!:mad:
 
This is normal. Batteries' readings can drop suddenly a few points and rise up again later.
 
Just use your machine and see if the battery life in general is satisfactory or not.
Focus on what you do, not on the battery percentage.

and some other questions ! ??

Last night i downloaded 3d game (toucgrind)from mac Appstore and played for just 1 or 2 minute, suddenly my laptop got heat ! and then fan stared working for around 15min and at that time, my battery went more down than then the other times , !!
1-is this normal that the fan works nonstop for 15 min !?
2-is that normal the laptop gets heat for a 2 minute 3d gaming?
3-is that normal that battery goes down more than other time , when the fan works?

Nothing shocking about that. Avoid playing heavy on graphics 3D game while on battery. Plug your MBA when you do that.

You're quite welcome!
Something I can also recommend is to get the iStat Dashboard widget. Among other things, it allows you to monitor the various temperature sensors inside your Mac (as well as the health of your battery). If you see your CPU temperature go above 90 Celsius and not going down, it's better to avoid the culprit application at all. Your CPU is designed to work at up to 100 C.
Keep in mind that the MBA is not designed for heavy-lifting computing.
