Has anyone had their iPhone battery replaced on their iPhone while they waited in an Apple store? I plan on making an appointment at my local store, and was wondering whether it’s something I could wait for in the store, or if I would have to come back later in the day, etc. Of course, I understand that it might vary somewhat depending on how busy the store is, but just looking for a ballpark. TIA.

Edit: Aternatively, if it’s too long of a wait, is it possible to drop it off and pick it up the next day?

only rocking about 4 hours per charge, so I thought it maybe time to let it's battery replaced. I know that can't be said generally, but how long does it usually take? I'd go to an authorized reseller, but that won't be much a difference to official stores. Is that a matter of hours, or is a send in needed, taking a couple weeks? Thanks
