It had nothing to do with avoiding the warranty. Period.

How can you make that assertion?


Worn out batteries may not be covered by the warranty.

"May not"? Why wouldn't a battery be covered under warranty? It isn't
specifically excluded.

batteries are excluded because they are a consumable part.

only if it's defective is it covered under warranty. normal wear and
tear is *not* covered.

if the battery fails a diagnostic test (or any other component) it will
be replaced under warranty. if it passes, then there's no reason to
replace it.

Did you read this in the Apple warranty? I'd like to see a copy.

This Warranty does not apply: (a) to consumable parts, such as
batteries or protective coatings that are designed to diminish over
time, unless failure has occurred due to a defect in materials or
workmanship; ...

it's a standard disclaimer.

The only test I really care about is running the phone the way it did when
new. If it doesn't do that the diagnostic test is pointless.

it's not a pointless test.

there's a big difference between a battery that's at 95% capacity after
a year (well within normal range) versus one that's at 60% capacity in
the same time frame, or has swollen or some other defect.
