Symptoms

- Considering whether to replace the battery or the whole phone
Likely causes
- CommonBattery naturally aged past its useful capacityThis is the most common reason people look into replacement cost.
- CommonConfirming AppleCare+ or warranty coverage before paying out of pocketA battery under 80% capacity within the first year, or covered by AppleCare+, may qualify for free or discounted service.
- PossibleComparing Apple's price against third-party repair shopsIndependent shops sometimes offer lower prices, with tradeoffs in parts and warranty.
What to do
- Check Settings > Battery > Battery Health & Charging for the current maximum capacity.
- Check whether the phone is still under its original one-year warranty or has AppleCare+, since battery service may be free if capacity is below 80% within that period.
- Look up Apple's published out-of-warranty battery replacement price for your specific iPhone model, since it varies by model.
- Compare that price against a reputable local or authorized third-party repair shop if considering alternatives.
- Ask any repair shop what type of battery they use and what warranty comes with the repair.
- Back up your phone before any battery service appointment.
- Factor in appointment wait times if going through Apple, versus walk-in options at some third-party shops.
- Weigh replacement cost against the value of the phone itself if it's an older model.
When to call a pro
Apple Stores, Apple Authorized Service Providers, and independent repair shops all offer battery replacement; official channels typically preserve warranty coverage best.
