Apple has increased the cost of out-of-warranty iPhone battery replacements by $20 for most models as of March 1st.
Back in January, Apple announced that starting in March, its battery service fee will go up by $20 for all iPhone models prior to the iPhone 14.
The current out-of-warranty battery service fee will apply until the end of February 2023. Effective March 1, 2023, the out-of-warranty battery service fee will be increased by $20 for all iPhone models prior to iPhone 14.
This means that an iPhone 13 Pro battery replacement that previously cost $69, now costs $89.
