Or is calibration still worth trying What it needs is a new battery. Apple does it as a complete swap of the top case. The exchanged part will receive a new battery and be refurbished where it can be used for a battery swap or a top case replacement.
If the current top case has issues, they'll replace it at price for repair of a top case, but that will include a new battery. Apple hasn't recommended any kind of "battery calibration" since before the Unibody MacBook Pro came out. That's about the time when the nominal rating for their lithium rechargeable batteries went from to cycles. However, there's no guarantee about that performance, and lithium rechargeable batteries inherently decline with age anyways.

For calibration, battery needs to stay in this charged condition for a considerable amount of time. For two hours, let the battery stay plugged in after full recharge. Meanwhile, you may continue working on it. After the stipulated two hours are over remove the power plug. Once you disconnect it, your MacBook Pro will start using its battery.
Continue working on battery power. At this point save your work documents and continue usage. At some point, the battery will exhaust its reserve power and automatically go into sleep mode.

Jan 27, AM in response to J-a-x In response to J-a-x Once the power gets low enough for the MacBook to go into safe sleep or turns off you need to leave it for five hours. I normally go ahead and turn mine off once it goes to sleep. That is a choice as the instructions say.
You have to leave it disconnected and the battery flat for five hours minimum or you have not done a calibration and just wasted a cycle for nothing. Turning it off for five hours after you started charging does nothing for the calibration it must occur before the charge begins. Reply Helpful Thread reply - more options Link to this Post. So my question was: if I turn it off when it sleeps, do I still have to wait wait 5 hours? Or is it a choice?
The instructions say to turn it off OR let it sleep for 5 hours. That seems like I have a choice: option 1: let it sleep for 5 hours. Do you see what I mean? You can either turn it off when it goes to sleep once the battery is drained or you can just let it sleep. Either way the battery must be flat and it must rest for five hours to let the battery chemistry stabilize. This is the same as when you charge it before calibrating you must have it fully charge for at least two hours before starting the calibration cycle.

Jan 27, AM in response to J-a-x In response to J-a-x Exactly but no matter which way you do it the battery must be flat before this is done. I always time it so that this occurs right before I go to sleep. Allow the MacBook to discharge completely and power off.

The battery is now fully calibrated, and the internal battery processor will deliver accurate battery-time-remaining estimates. It doesn't hurt the battery if you forget to perform the calibration routine; it just means you're not getting the best possible performance from the battery. However, after the battery is calibrated, its remaining time indicator is more accurate. Over time, as the battery accumulates charges and discharges, its performance changes.
The appropriate time between calibrations depends on how often you use your Mac. The process doesn't hurt anything, so it's safe to calibrate the battery a few times a year.
