Will apple replace battery without warranty
I apologize if this is a dumb question. My ipod 4gen has a battery that's practically useless, due to the fact it can hold a charge for 20 minutes max. My question is will the Apple store replace the battery for me without a warranty? The friend I got this iPod from doesn't have one. And another question, my friend has a brand new battery for it. Will they replace it for me? Thanks in advance!(:
iPod touch, iOS 6.1.6
