If I replace iPhone6 battery (because it is not keeping charge well) by making an appt. to have it changed, will the total cost be $29.00. Can this be done throughout 2018? Thank You, NB

Yes total cost will be $29. Don't know if it's valid for rest of 2018

No idea call somebody that works there.... or upgrade to an Android phone

Only valid through January, I heard. You need to make an appt., not available by walking in. To reserve your battery, they need the IMEI # from your phone, which you can find under settings.

It is good until the end of 2018. Call AppleCare so they can order it for you and save a trip to the store.
