Apple's official battery replacement costs between $69 and $99, depending on your iPhone model

Apple charges a flat rate for out-of-warranty battery replacement at their stores and through their mail-in service. An iPhone 15 or iPhone 14 costs $69. Older models like the iPhone 13, 12, 11, and X cost $69 to $79. iPhone XS, XR, and 8 models cost $79. The original iPhone 6, 7, and SE cost $49. These prices do not include diagnostic fees, which Apple may charge separately if they need to test your phone first.

If your battery is still under the one-year limited warranty and the battery has genuinely failed (not just degraded from normal use), Apple replaces it for free. AppleCare+ extends this to two years and also covers accidental damage, but costs $99 to $199 upfront depending on your model. If you have AppleCare+, battery replacement is free for the duration of the plan.

You can check your battery health yourself before paying for anything. Go to Settings > Battery > Battery Health & Charging. If your maximum capacity is below 80 percent and your phone is still under warranty or you have AppleCare+, you may be covered. Apple considers a battery defective if it retains less than 80 percent capacity within the warranty period.

Key Takeaways

  • Apple's out-of-warranty battery replacement costs $69 to $79 for current and recent iPhone models, with older models sometimes less.
  • Battery replacement is free under the standard one-year warranty if the battery has genuinely failed, not just degraded from normal use.
  • AppleCare+ covers battery replacement at no cost for two years, but requires paying $99 to $199 upfront when you buy your phone.
  • You can check your battery health in Settings to see if it has dropped below 80 percent before deciding whether to replace it.
  • Third-party repair shops charge $30 to $60 but may void your warranty and use non-Apple parts.

Where to get your battery replaced

Apple has three official routes: an Apple Store, an Apple Authorized Service Provider, or Apple's mail-in service. Apple Stores give you the fastest turnaround, usually same-day or next-day if you book an appointment through the Apple Support app or website. Authorized Service Providers are independent repair shops certified by Apple and typically charge the same price, though wait times vary by location.

Apple's mail-in service is free shipping both ways. You start a repair request on apple.com, print a prepaid shipping label, and send your phone in. Turnaround is usually five to seven business days, plus shipping time. This route works if you have no Apple Store nearby or do not mind being without your phone for a week or two.

Independent repair shops like iFixit, Best Buy's Geek Squad, and local phone repair stores charge less — typically $30 to $60 — but use third-party batteries that may not be identical to Apple's. Some of these shops offer same-day service. The trade-off is that using a non-Apple battery may affect your warranty, and the battery itself may not last as long or hold charge as reliably as an Apple part.

What happens to your warranty when you replace the battery

If you use Apple or an Apple Authorized Service Provider, your warranty is not affected. The replacement battery itself comes with a 90-day warranty covering defects in that battery alone. Your phone's overall warranty remains unchanged — it still covers hardware failures for the remainder of your original one-year period, or for two years if you have AppleCare+.

If you use an independent repair shop, the situation depends on your phone's age and the shop's policies. If your phone is still under Apple's one-year warranty, using an unauthorized repair shop may void the warranty on the entire device, though Apple's warranty does not technically cover battery degradation from normal use anyway. If your phone is out of warranty, using an independent shop has no effect on your coverage because there is no coverage left to lose.

Signs your battery actually needs replacing

A battery that has genuinely failed shows specific patterns. Your phone shuts down suddenly even when the battery percentage shows 20 or 30 percent remaining. It will not turn back on until you plug it in. This happens repeatedly and gets worse over time. This is different from normal battery degradation, where your phone straightforward does not last as long through the day as it used to.

Another sign is rapid percentage drops. You unplug your phone at 100 percent, use it normally for 20 minutes, and the battery jumps from 60 percent to 20 percent. Or your phone gets noticeably hot during normal use, which can indicate a battery problem. Check your battery health in Settings first — if it shows 80 percent or higher and your phone is not shutting down unexpectedly, the battery is probably fine and you are just experiencing normal aging.

If your maximum capacity is between 80 and 90 percent, your battery is degraded but not defective. Many people keep using their phones at this level for months or years. The decision to replace depends on whether the shorter battery life bothers you enough to justify the cost.

How battery degradation works and why it happens

Every rechargeable lithium battery loses capacity over time. Apple rates their batteries to retain 80 percent of their original capacity after 500 full charge cycles. A charge cycle means draining the battery completely and recharging it to 100 percent. If you charge your phone every day, you hit 500 cycles in roughly 18 months. After that point, the battery naturally holds less charge.

This is not a defect — it is how lithium batteries work. Heat, age, and the number of times you charge all speed up degradation. If you leave your phone plugged in constantly, charge it in a hot car, or live in a warm climate, your battery will degrade faster. If you charge it once a day in a cool room, it will degrade more slowly. There is no way to stop this process entirely, only to slow it down.

Apple's iOS shows you this degradation in Battery Health. When the number drops below 80 percent, Apple considers the battery may be able to access for replacement under warranty. When it drops below 50 percent, your phone may start showing a "Low Power Mode" warning more often or shut down unexpectedly to protect the battery from damage.

Comparing the cost of replacement versus buying a new phone

A battery replacement at $69 to $79 makes sense if your phone is otherwise working well and you want to keep it for another year or two. If your phone is three years old and the battery is failing, replacing the battery extends its life significantly. Most people get another 18 to 24 months of use from a phone after a battery replacement.

A new iPhone costs $800 to $1,200 depending on the model. If your current phone is paid off and working except for the battery, spending $70 to replace it is much cheaper than upgrading. However, if your phone is also showing other problems — a cracked screen, slow performance, or software that no longer updates — a battery replacement alone may not be worth it.

Consider also that older phones receive fewer years of software updates. An iPhone 11 receives updates until roughly 2026 or 2027. An iPhone 6 stopped receiving updates in 2020. If your phone is so old that it no longer gets security updates, a battery replacement keeps it running but does not address the security risk of using outdated software.

How to extend your battery's life before it needs replacing

Charge your phone in a cool environment. Avoid leaving it plugged in overnight or in a hot car. Use optimized battery charging, which is on by default in iOS. Go to Settings > Battery > Battery Health & Charging and make sure "Optimized Battery Charging" is turned on. This feature learns your charging patterns and slows down charging to 80 percent until you actually need the full charge, which reduces wear.

Keep your phone's software updated. Apple releases updates that improve battery efficiency and fix bugs that drain power unnecessarily. Enable automatic updates in Settings > General > Software Update > Automatic Updates. Avoid using your phone while it is charging, as this generates heat and speeds up degradation.

Turn off background app refresh for apps you do not need running constantly. Go to Settings > General > Background App Refresh and disable it for apps that drain battery without adding value. Reduce screen brightness or enable auto-brightness. The display is the biggest battery drain on most phones, so lowering brightness extends the time between charges and reduces overall stress on the battery.

Frequently Asked Questions

Can I replace my iPhone battery myself?

Technically yes, but it is difficult and risky. iFixit sells battery replacement kits for $20 to $40, but opening an iPhone requires special tools and careful handling. You can easily damage the screen, water seals, or internal components. If something goes wrong, you have voided your warranty and may have a broken phone instead of just a dead battery. Unless you have experience with phone repair, paying Apple or a repair shop is safer.

Does AppleCare+ cover battery replacement?

Yes, battery replacement is free under AppleCare+ for the entire two-year coverage period. AppleCare+ costs $99 to $199 upfront depending on your iPhone model, so it only makes financial sense if you think you will need repairs beyond just the battery. If you only want battery coverage, paying $69 when the battery fails is cheaper than paying $99 to $199 upfront.

What if my phone is still under warranty but the battery is degraded, not dead?

Apple's one-year warranty covers batteries that have genuinely failed, not batteries that have straightforward degraded from normal use. If your battery health shows 85 percent and your phone is not shutting down unexpectedly, Apple will not replace it for free. You would need to pay the out-of-warranty price. If your battery health is below 80 percent and you are still within the warranty period, contact Apple Support to discuss whether it qualifies as a defect.

Will a third-party battery work as well as an Apple battery?

Most third-party batteries work adequately but may not last as long or hold charge as consistently as Apple's. They are usually cheaper upfront, but you might replace them again sooner. Some independent shops use refurbished Apple batteries, which are more reliable than generic third-party batteries. Ask the repair shop what brand of battery they use before you commit.

How do I know if my battery is failing or if something else is draining power?

Check Battery Health in Settings > Battery > Battery Health & Charging. If maximum capacity is 80 percent or higher, your battery is probably fine. If your phone is draining quickly despite good battery health, the problem is likely a misbehaving app or a software bug, not the battery itself. Try restarting your phone or updating to the latest iOS version. If the problem persists, contact Apple Support to diagnose the real cause.
