iPhone replacement battery warranty

Oh!!! That sounds like a swollen Battery, which can happen with lithium ion batteries. Take it back to Apple so they can confirm the damage was caused by a swollen battery and they should replace the phone at just a battery service fee if it was caused by the battery.

Also don’t be disappointed in Apple because a 90 day repair warranty is a lot more than most other companies give, which is 30 days or nothing.

If not the original battery it’s 90 days or the remainder of the iphone warranty, whichever is longer.

The battery has a one year from purchase date warranty if defective.
