    iPhone batteries wear down after a few years and hold less charge. Learn how to check your battery health, when it is time to replace it, and how much it costs.

    1. Step 1. Check Your Battery Health

      Go to SettingsBatteryBattery Health & Charging. You see your battery's "Maximum Capacity" as a percentage. 100% is new. Apple recommends replacement when it drops to 79% or below. If you also see a message about "Peak Performance Capability" with a yellow warning, your battery is limiting performance.

      Quick Tip

      Quick Tip: If your phone dies unexpectedly at 20–30% battery or has started randomly shutting down, a failing battery is often the cause even if health shows above 80%.

    2. Step 2. Consider Replacement at 79% or Below

      At 79% or lower maximum capacity, your battery holds roughly 21% less charge than it did when new. That means a full day that used to last until 10 PM might now end at 7 PM. A replacement battery restores full capacity and a full day of battery life.

    3. Step 3. Check the Replacement Price

      Battery replacement prices at Apple: most iPhones cost $99 to replace the battery (as of 2026). If you have AppleCare+, battery replacement is free when capacity drops below 80%.

    4. Step 4. Schedule a Battery Replacement

      Go to getsupport.apple.com. Choose iPhoneBattery, Power & ChargingBring In for Repair. Log in with your Apple ID. Choose a nearby Apple Store or Authorized Service Provider. Select a date and time. Back up your iPhone before the appointment: Settings → [your name] → iCloud → iCloud BackupBack Up Now.

      Warning

      Always back up your iPhone before any repair. While battery replacement does not usually affect data, it is good practice in case of anything unexpected during the repair.

    5. Step 5. After Replacement

      After your battery is replaced, your Maximum Capacity returns to 100%. Charge the battery a full cycle (0% to 100%) once in the first few days to help calibrate the new battery indicator. You should notice the phone lasting noticeably longer through the day.

    iPhone batteries are designed to retain up to 80% of their original capacity after 500 complete charge cycles (roughly 1–2 years of normal use). After that, battery health declines. And you may notice your phone does not last as long through the day, shuts down unexpectedly, or charges slowly.

    The good news: a battery replacement is usually much cheaper than buying a new phone. And it can make an older iPhone feel like new again. Apple offers battery replacement at Apple Stores and Apple Authorized Service Providers for a set price depending on the model.

    Your iPhone tracks its own battery health as a percentage. A new battery is 100%. Apple recommends replacing the battery when it drops below 80% — below that level, performance throttling may kick in to prevent unexpected shutdowns.

    Battery replacement takes about 1–2 hours at an Apple Store or authorized repair shop. Apple offers a mail-in service if there is no store nearby. Third-party repair shops also replace batteries, often at lower cost.

    After replacement, your iPhone charges faster, lasts longer, and unexpected shutdowns should stop.
