    My battery in the last 2 days have been showing battery time of 4.15 or 4.00 hours when full charged ,I don't recall it being more than 3.25 h when i got it 2 month ago, is this an indication of something wrong going on here?:eek:

    Don't worry about it, your battery meter has just drifted out of calibration. Unless knowing how much battery time is left is ever important to you, than don't sweat it. If it is important to you then you can recalibrate it very easily.

    The time remaining will fluctuate depending on the health of the battery and it's capacity. Try CoconutBattery, it's useful in assisting it's overall battery health, also give you some indication as to what's happening inside. Just don't get too obsessed with it, it's just a guide.

    Though... if the overall charge drops below 80% of it's original capacity in the first few 3 months of general usage, call Apple!! Because they will be able to issue you a new battery as yours is under-performing.
