Do I Have to Leave My MacBook Pro for Battery Repair at the Genius Bar?

Yeah, you'll definitely need to leave your MacBook there. Generally, most stores take about 7-10 days for repairs, sometimes longer. Often, your laptop will be sent off to a repair center and then shipped back to you. Just a heads up, make sure all your data is backed up because there's always a risk of data loss during repairs!

It really depends on whether they have the battery in stock and how busy their repair schedule is. Honestly, it’s hard to say for sure without checking those specifics.

From my experience, it won’t be a same-day fix. You have to leave it for a bit, and if they don't have the part in stock, they'll order it and ask you to come back later. Typically, it could take about 5-10 days for the repair.
