QUOTE(Kernkraft400 @ Jan 8 2010, 02:46 AM) What is the implication if i turn on my MacBook Pro 13" for hours and hours with charger on? Maybe days, because i need to burn in my headphone if u guys know what i mean. Also, what happens if we don't have AppleCare and our battery doesn't work?Can retailers help us change the battery on the spot? i leave my MBP on for days when i have something to download. doesnt seem to have any bad effects to me, juz make sure it gets adequate cooling n dont put on soft stuff like mattresses and pillows. what headphone have u got there?  |

I have just bought Grado Labs Alessandro's MS1i. I am burning-in the headphone using pink noise now on my MacBook Pro. I hope everything goes well  |

Those are nice headphones you've got there. I have the SR225 myself.
You could just plug it in to a radio or portable player if you don't want to keep your Mac on.

The only portable player i have with me now is the iPhone. I wouldn't want to mess with the iPhone either, because i dont want it to have a shorter battery lifespan. You know how fragile the iPhone is  I didn't know you're a fellow audiophile also  |

Hi all . I have the 15MBP bought 2 months back. even at full charge I get about 6 hours of "projected" usable battery time. I only have finder, firefox and wifi running. the screen is down to the minimum and the keyboard lights were off. I tot it should average about 7-8 hrs of common use??

[g] firefox quite RAM hungry, moreover if u open a website that has flash stuff. this can lower battery life |

but most sites will have some amount of flash or some form of java. then again 6 hours is pretty good.. compared to my office laptop.. 1.5 hours LOL!

hi guys,
Is it each calibration on the battery cycle, the mAh on the battery will drops?
Mine battery is 4800 mAh.
Current is 4646 mAh
Today is at 28 cycles.
is there a way to maintain or slower down the mAh ?

jing-leBelle,
Roughly drops around 150mAh each 20 cycles...
Some guys in previous page managed to control the mAh closer to original capacity. Wonder what's the magic trick.
i am calibrating once within 1 or 2months.
edit : sorry typo : 20 cycles..haa
