When and how to get your iPhone battery replaced

Apple and authorized repair shops can replace your iPhone battery, but the process and cost depend on whether your phone is still under warranty and which model you have. If your battery health has dropped below 80 percent, or if your phone shuts down unexpectedly even when the battery shows charge, a replacement is usually the next step. You have three main routes: Apple's official service, an Apple Authorized Service Provider, or an independent repair shop — each with different timelines, costs, and warranty coverage on the new battery.

The fastest way to understand your options is to check your battery health first using your phone's built-in tool, then contact Apple directly or visit an Apple Store to get a repair estimate. Apple typically replaces batteries within one to two business days at a store location, though mail-in service takes longer. Independent shops often cost less but may not use genuine Apple parts, which can affect performance and future repairs.

Key Takeaways

  • Check your battery health in Settings > Battery > Battery Health & Charging to see the current capacity percentage before deciding on a replacement.
  • Apple Store replacements usually cost between $69 and $99 depending on your iPhone model, and take one to two business days.
  • If your phone is under AppleCare+ coverage, battery replacement is free if the battery capacity has dropped below 80 percent.
  • Independent repair shops may charge less but typically cannot access Apple's genuine parts or provide the same warranty on the replacement battery.
  • Mail-in battery service through Apple takes five to seven business days total, including shipping time.

How to check your iPhone battery health

Your iPhone tracks battery health automatically and displays it in the Settings app. Open Settings, tap Battery, then tap Battery Health & Charging. You will see a percentage labeled "Maximum Capacity" — this tells you how much charge your battery can hold compared to when it was new. A battery at 80 percent or lower is considered degraded and may benefit from replacement, though the phone will still work.

The same screen also shows "Condition" — if it says "Normal," your battery is functioning as expected. If it says "Service Recommended" or "Service Battery," Apple is flagging that the battery should be replaced soon. You do not need to replace it when ready, but scheduling service within the next few weeks is a good idea to avoid unexpected shutdowns.

Apple Store and authorized service replacements

An Apple Store or Apple Authorized Service Provider can replace your battery with a genuine Apple part and provide a one-year warranty on the replacement. To start, visit apple.com/support, select your device, and choose "Battery Service" from the menu. You can book an appointment online or call your nearest Apple Store directly. Bring your phone and a valid ID; you do not need to back up your data beforehand, though it is always a good idea.

The cost varies by iPhone model but typically ranges from $69 to $99 for out-of-warranty replacements. If you have AppleCare+ coverage, battery replacement is free as long as the battery capacity is below 80 percent. The repair usually takes one to two business days if you drop it off, or you can wait in the store for a same-day replacement if the location has parts in stock. Ask when you book whether your store offers same-day service.

Mail-in battery service through Apple

If you do not have an Apple Store nearby, you can mail your phone to Apple for battery replacement. Start at apple.com/support, select your device, and choose "Mail In Repair." You will receive a prepaid shipping label and instructions for packing your phone safely. Apple will inspect it, replace the battery, and ship it back — the entire process typically takes five to seven business days, not counting time for you to pack and drop off the box.

Mail-in service costs the same as in-store replacement ($69 to $99 for most models) and includes the same one-year warranty on the new battery. You will receive email updates as your phone moves through the repair process. Before you ship, back up your data using iCloud or a computer, just in case Apple needs to troubleshoot other issues while your phone is in their hands.

Independent repair shops and third-party batteries

Independent phone repair shops often charge $30 to $60 for battery replacement, significantly less than Apple. However, they typically use non-genuine batteries, which may not hold charge as long or perform as reliably as Apple's original parts. Some independent shops source refurbished or aftermarket batteries that carry no warranty or a limited one (often 30 to 90 days).

Before choosing an independent shop, ask whether they use genuine Apple batteries or third-party alternatives, and what warranty they provide on the replacement. If you plan to keep your phone for several more years, the lower upfront cost may not be worth the risk of a battery that degrades faster or fails sooner. If you are selling the phone or upgrading soon, an independent replacement may be a reasonable choice.

What to do before your battery replacement appointment

Back up your iPhone using iCloud or a computer before you go in for service. Open Settings > [Your Name] > iCloud > iCloud Backup and tap "Back Up Now," or connect your phone to a computer and use Finder (Mac) or iTunes (Windows) to create a full backup. This protects your photos, messages, and app data in case anything unexpected happens during the repair.

Disable Find My iPhone before you drop off your phone. Go to Settings > [Your Name] > Find My > Find My iPhone and toggle it off. Apple requires this step before they can service your device, and it only takes a few seconds. If you forget, the repair shop will ask you to do it before they begin work, which may delay your appointment.

Timeline and what to expect after replacement

After your battery is replaced, your phone will show 100 percent battery capacity in Settings > Battery > Battery Health & Charging. The new battery will have a one-year warranty from Apple (or the warranty period offered by an independent shop). Your phone will perform normally — there is no "break-in" period for a new battery, and you can use it right away at full charge.

If you used an independent shop and the replacement battery fails within the warranty period they offered, contact that shop directly. If you used Apple or an authorized provider and the battery fails within one year, you can return to the same location or any Apple Store for a free replacement under warranty. Keep your receipt as proof of the service date.

Frequently Asked Questions

Can I replace my iPhone battery myself?

Apple does not sell batteries to consumers for self-replacement, and opening your phone yourself will void any remaining warranty. Some third-party battery kits exist online, but they require specialized tools and risk damaging the display, water seals, or other components. Professional replacement is safer and comes with a warranty.

How long does a new iPhone battery last?

A new battery should retain 80 percent capacity for roughly two to three years under normal use, depending on your charging habits and how often you use the phone. Charging overnight, using fast charging frequently, or keeping your phone hot while charging will degrade the battery faster than moderate use.

Will replacing the battery erase my data?

No, battery replacement does not erase your data. The battery is a separate component that does not store information. However, backing up before service is still wise in case the technician needs to troubleshoot other issues or your phone is damaged during repair.

Is it worth replacing the battery or should I just buy a new phone?

If your phone is otherwise working well and you plan to use it for another year or two, battery replacement ($69 to $99) is much cheaper than a new phone. If your phone has other hardware problems, is several years old, or you want the latest features, upgrading may make more sense financially.

What if my phone is out of warranty and I cannot afford the repair?

An independent repair shop will cost less upfront, though the battery may not last as long. You can also extend the phone's usable life by enabling Low Power Mode in Settings > Battery, which reduces performance but uses less battery. This buys you time to save for a repair or replacement.
