I'm noticing a pattern emerging here when trusting buyers are calling Apple service technicians for help regarding this specific new product concern:
Trusting buyer purchases new cycle 2020 iPad Air 4.
Trusting buyer notices immediately upon opening and operating an unusual & unexplainable battery drain while unit is idle.
Trusting buyer calls Apple for help.
Apple service technician informs buyer to purchase a new cord from Apple to backup the unit before help can commence.
Trusting buyer purchases new cord from Apple for backup.
Trusting buyer again calls Apple service technician.
Apple service technician instructs buyer to perform factory reset using newly purchased cord from Apple.
Trusting buyer performs backup as instructed; no change in solving the iPad Air 4's battery drain.
Trusting buyer informs Apple service technician of the non-change.
Apple service technician informs now-skeptical buyer that all looks normal on their end, and goodbye.
Please note: Apple does not meet the specific call-to-action on behalf of the trusting buyer, nor do they fix the original source of the problem, namely the suspected (and in many cases confirmed over the phone with Apple) defective battery drain; Apple does, however, successful convince the trusting buyer that they need to spend an additional $19 on a cord before they will try to fix an issue that never should have occurred in the first place. In effect Apple generates additional revenue from the trusting buyer by preying on their desperation to remedy a seemingly defective situation out-of-the-box.
This, dear readers, reads like a scam.
