Warranty concern for iPhone battery with 89% capacity and 321 recharge cycles

Hello, I bought a phone on March 26, 2025, and today, on October 18, my phone's battery is at 89% and has 321 recharge cycles. The phone is quickly running out of power, and I'm wondering if this is a warranty issue. Can you replace the battery or return money for this telephone ?

Apple will replace the battery free of charge if the Maximum Capacity has dropped below 80% in the first year of operation.


If you purchased the phone new from an authorized Apple seller, the warranty on the battery will expire on March 25, 2026, so your battery's Maximum Capacity would need to be less than 80% before that date to qualify for a free replacement.
