There are at least four businesses within three miles of where I live that will be happy to do it for you while you wait, requiring no shipping, and fairly inexpensive. As I said, you can also do-it-yourself. I just spent an hour replacing my daughter's iPad 3's digitizer screen which she had dropped and cracked. It was fairly easy to do. I could have replaced the batteries while I had it apart. It didn't need replacement batteries.
I wouldn't recommend doing it yourself with apple device. Way too complicated for the average person - fragile flex circuits, etc. Like trying to fold a map.
Why buy batteries or replacement services from Apple. There are thousands of businesses wiling to do it for your economically and quickly.
You want Apple to give you $500 on your next purchase because you don't know how to replace your previous purchase batteries?. How long did those devices last for you? How much use did you get out of them before the batteries would no longer take a charge? I have no doubt they lasted for years. YOU decided it was not worth a small charge to replace the batteries to restore your Apple devices to full functionality, not Apple.
You think you are being "fair"? You apparently want your products with free services for life and to never be superseded by later models. You are being ridiculous to say you are being fair.
So they don’t charge for replacing the battery? And there is zero taxes charged for the service? Wow. /sarc
And do they replace the unit if they damage it while trying to replace the battery. In a device that is not designed to be taken apart.
My friend took her phone into one of those places multiple times for repair paid the fee and ended up tossing the phone in the trash. They damaged a flex circuit connector and it couldn’t be repaired.
Something as simple as replacing a battery shouldn’t require brain surgery.
No, replacing the battery in an apple device not at all feasible because their engineers designed that way. They designed in obsolescence.
It is simpler and probably cheaper to buy a new one. But that is what Apple is hoping for.
