Yes, iPhone batteries can be replaced, but the cost and process depend on your model and whether you use Apple or a third party
Apple will replace the battery in any iPhone model, though the price varies by device. As of early 2024, an out-of-warranty battery replacement at an Apple Store or through Apple's mail-in service costs between $69 and $99 for most current models. If your iPhone is still under the one-year limited warranty or you have AppleCare+, the replacement may be free or cost less. Third-party repair shops often charge $30 to $60, but quality and warranty coverage vary widely.
You can also replace the battery yourself using a kit from retailers like iFixit, which typically costs $20 to $40 plus tools. This route requires patience and carries the risk of damaging the phone if you make a mistake. Most people choose Apple or a trusted local repair shop because the work is may provide and takes less than an hour at a store location.
Key Takeaways
- Apple charges $69 to $99 for out-of-warranty battery replacement at most locations, and the service is free if your phone is under warranty or you have AppleCare+.
- Third-party repair shops typically charge $30 to $60 and may complete the work faster than Apple, but warranty coverage depends on the shop's policies.
- DIY battery replacement kits cost $20 to $40 but require tools and skill; a mistake can damage the phone permanently.
- Battery replacement usually takes less than an hour at an Apple Store, though mail-in service takes one to two weeks.
- Most iPhones show a battery health percentage in Settings, and Apple recommends replacement when capacity drops below 80 percent.
How to check your iPhone battery health before replacing it
Your iPhone displays a battery health percentage in the Settings app. Open Settings, tap Battery, then Battery Health & Charging. The number shown is the maximum capacity your battery can hold compared to when it was new. A battery at 80 percent capacity still works, but it drains faster and may shut down unexpectedly under heavy load.
Apple does not require a minimum health percentage to perform a replacement, but most people wait until capacity drops to 70 to 80 percent before spending money on the service. If your phone shuts down suddenly even when the battery percentage shows 20 or 30 percent remaining, that is a sign the battery is failing and replacement will solve the problem.
Apple's battery replacement process and timeline
At an Apple Store, a technician will run a diagnostic to confirm the battery needs replacement, then swap it out while you wait. The entire visit usually takes 30 to 60 minutes. You can book an appointment online or walk in, though walk-ins may have a longer wait during busy hours. The store will back up your data before the repair, so you do not lose anything.
If you mail your iPhone to Apple, the process takes one to two weeks from the time you ship it. You will need to include proof of purchase or your Apple ID information. Apple will return the phone with a new battery and a 90-day warranty on the replacement part. This option costs the same as an in-store replacement but is useful if no Apple Store is nearby.
Third-party repair shops versus Apple
Independent repair shops and chains like Best Buy's Geek Squad offer battery replacement for less money than Apple, usually $30 to $60. Many complete the work in under an hour. The trade-off is that warranties vary — some shops offer 30 to 90 days of coverage on the battery, while others offer none. Before choosing a shop, ask whether they use genuine Apple batteries or third-party alternatives, and what happens if the battery fails after the repair.
Third-party batteries are usually cheaper but may not last as long or perform as reliably as Apple's. Some shops use refurbished Apple batteries, which cost less and carry the same performance as new ones. If you choose a third-party shop, pick one with good reviews and a clear warranty policy in writing.
DIY battery replacement: cost, tools, and risks
A DIY battery kit from iFixit or similar retailers includes the battery, adhesive strips, and basic tools like a pentalobe screwdriver and plastic pry tools. The total cost is usually $20 to $40. You will also need a heat gun or hair dryer to soften the adhesive holding the old battery in place, and a clean workspace with good lighting.
The process takes 30 minutes to two hours depending on your skill level and the iPhone model. Newer iPhones have more adhesive and are harder to open than older models. If you crack the screen, damage the logic board, or puncture the battery during removal, the phone may be unusable. Once you open the phone, any water resistance is compromised unless you replace the seals, which most DIY kits do not include. For these reasons, DIY replacement is best suited to people who have repaired phones before or are comfortable with the risk of permanent damage.
What to expect if your iPhone is still under warranty
If your iPhone is within one year of purchase and the battery capacity has dropped below 50 percent, Apple will replace it at no cost under the limited warranty. You do not need to pay anything — bring the phone to an Apple Store or mail it in, and the service is free. If the battery is between 50 and 80 percent capacity, the warranty does not cover it, and you will pay the standard replacement fee.
If you have AppleCare+, battery replacement is free regardless of capacity, as long as the phone is not physically damaged. AppleCare+ costs $99 to $199 depending on the model and is usually purchased at the time you buy the phone, though you can add it within 60 days of purchase at some locations.
How long a new battery lasts and when to replace it again
A new iPhone battery is designed to retain 80 percent of its capacity after 500 full charge cycles. A charge cycle is one complete discharge and recharge, not the number of times you plug in the phone. Most people complete 300 to 400 cycles per year, so a new battery typically lasts three to four years before capacity drops below 80 percent again.
Battery lifespan depends on how you use the phone. Charging overnight, using the phone while it charges, and exposing it to heat all wear the battery faster. Keeping the phone between 20 and 80 percent charged and avoiding extreme temperatures extends battery life. If you replace the battery now and change your charging habits, the next replacement may not be necessary for four or five years.
Frequently Asked Questions
Does replacing the iPhone battery void the warranty?
No. An Apple battery replacement comes with a 90-day warranty on the new battery itself. The rest of your phone's warranty remains unchanged. If you use a third-party shop, the warranty on the replacement battery depends on that shop's policy, but it does not void Apple's warranty on other parts of the phone.
Can I replace the battery myself without opening the phone?
No. The battery is glued inside the phone and cannot be removed without opening the case. There is no external access panel or user-replaceable battery compartment on any current iPhone model. You must either take it to a repair shop or open the phone yourself.
What happens if I replace the battery with a non-Apple part?
Third-party batteries work, but they may not last as long or perform as reliably as genuine Apple batteries. Some third-party batteries have lower capacity or drain faster. If the battery fails, you will need another replacement. Stick with Apple batteries or refurbished Apple batteries from reputable shops if you want the best performance and longevity.
Is it cheaper to replace the battery or buy a new phone?
Battery replacement is almost always cheaper. A new iPhone costs $800 to $1,200, while a battery replacement costs $69 to $99 at Apple. Unless your phone has other serious damage or is very old, replacing the battery extends its life by several more years at a fraction of the cost of a new device.
Can I use my iPhone while the battery is being replaced?
No. At an Apple Store, the technician will keep your phone during the repair, which takes 30 to 60 minutes. You can wait in the store or leave and return later. If you mail it to Apple, you will not have the phone for one to two weeks. Plan accordingly if you rely on your phone for work or daily use.
