    I calibrated my battery last week and I'm pretty sure I'm getting worse battery life after the fact. Has anyone had this experience? Can battery calibration hurt your battery?

    I have no battery issues so far. The Calibration help keep the battery healthy and live longer and keep an accurate reading if you have iStat. Beside All battery will eventually dies as time passes..so everyone's battery will degrade at some point.

    No, it won't make it worse. It was probably just mis-calibrated before and thought it had more juice than it did. So while the battery may 'appear worse' after calibration, it is not.

    I doubt it will make it worse. I haven't even calibrated my Al MacBook's battery yet and it has been in great shape.

    Yes, there is. It's a slightly different process (after the battery runs down, you let it rest for about 5 hours before recharging), but you should definitely still calibrate.

    adorable :)

    I don't think we'll ever need to stop calibrating batteries. Same with displays. Maybe you're thinking of cycling the battery...

    Nope, there may be something wrong with your battery.

    Calibrating the battery will actually harm the cells, lithium cells HATE being at 100% or 0% charge. The reason it is recommended is because it will align the charge circuits in the batteries to know exactly how much charge the cells can hold. Proper maintenance of the batteries, such as not constantly being left at 100% charge and storing at 60% charge if not being used for an extended period of time is better for the overall health of the battery.

    Agreed with most here. It will not make it worse.

    If you think you're having battery issues, take it in sooner than later. I took in my MBP because I thought the battery life was a little too low about a month before the year mark. They swapped it out with no questions asked. Just check your battery health.
