You can replace an iPhone battery yourself with the right tools, but Apple's service is safer for most people

Replacing an iPhone battery yourself is possible if you have a pentalobe screwdriver, a spudger, and patience — but it voids your warranty and risks damaging the screen or logic board if you slip. Apple will replace the battery for a flat fee (usually $69 to $99 depending on your model) and takes one to three business days. Third-party repair shops charge $40 to $80 and often finish the same day. The choice depends on whether you value speed, cost, or the safety net of a warranty.

Your iPhone's battery degrades over time. After about 500 full charge cycles, a lithium battery holds roughly 80 percent of its original capacity. Once it drops below 80 percent, you may notice your phone shuts down unexpectedly at low battery percentages, or the performance slows down. Replacing the battery restores the phone to normal speed and runtime.

Key Takeaways

  • Apple charges $69 to $99 to replace your battery and covers the work under warranty, but the process takes one to three business days.
  • A DIY battery replacement requires a pentalobe screwdriver, spudger, and adhesive strips, and risks damaging your screen or internal components if you make a mistake.
  • Third-party repair shops typically charge $40 to $80 and complete the work the same day, but may not use genuine Apple parts.
  • You can check your battery health in Settings > Battery > Battery Health & Charging to see the current capacity percentage.
  • If your iPhone is still under warranty or AppleCare+, battery replacement is free if the capacity has dropped below 80 percent.

Check your battery health before you decide

Open Settings, tap Battery, then tap Battery Health & Charging. You will see a percentage labeled "Maximum Capacity" — this is how much charge your battery holds compared to when it was new. If it is 80 percent or higher, your battery is still within normal wear. If it is below 80 percent, Apple considers it degraded and will replace it.

You will also see a "Condition" line that says either "Normal" or "Service Recommended." If it says "Service Recommended," the battery has degraded enough that Apple will replace it at no cost if you are still under warranty or have AppleCare+. If you are out of warranty, you pay the service fee.

Apple's battery replacement service

Visit apple.com, go to Support, select your iPhone model, and choose "Battery Service." You can book an appointment at an Apple Store or mail your phone to Apple's repair center. At an Apple Store, the appointment usually takes 30 minutes to an hour, but the phone stays for one to three business days while they run diagnostics and complete the swap. If you mail it in, add two to three days for shipping each way.

Apple uses genuine parts and covers the replacement under warranty. If something goes wrong during the repair — a cracked screen, a logic board failure — Apple is responsible. You also get a 90-day warranty on the new battery itself. The cost is $69 for iPhone 14 and earlier models, and $99 for iPhone 15 and later. If your phone is under warranty or you have AppleCare+ and the battery capacity is below 80 percent, the service is free.

Third-party repair shops

Local phone repair shops and chains like uBreakiFix or Best Buy's Geek Squad offer battery replacement for $40 to $80 and often complete it the same day. The trade-off is that they may not use genuine Apple batteries — some use aftermarket batteries that work but may not last as long or hold charge as reliably. Ask the shop whether they use original or third-party parts before you hand over your phone.

Third-party shops do not carry Apple's warranty, so if the new battery fails or the repair damages something else, you have limited recourse. Some shops offer a 30-day or 90-day warranty on their work, but it is narrower than Apple's. Check reviews on Google or Yelp for the specific shop before you go, because quality varies widely.

DIY battery replacement with tools

If you choose to replace the battery yourself, you will need a pentalobe screwdriver (the five-pointed star shape used on iPhones), a spudger or plastic pry tool, tweezers, a heat gun or hair dryer, adhesive strips, and a replacement battery kit. Kits cost $20 to $40 on Amazon or eBay and include most of these items. Watch a video tutorial for your specific iPhone model on YouTube before you start — the steps differ slightly between models.

The basic process is: heat the edges of the phone to soften the adhesive, carefully pry open the back panel, disconnect the battery connector, peel away the old battery, clean the adhesive residue, install the new battery, reconnect it, and seal the phone back up with new adhesive strips. The whole job takes 30 minutes to an hour if you are careful. The risk is that you slip with the spudger and crack the screen, or you damage the battery connector and the phone will not power on.

A DIY replacement voids your warranty. If you damage the phone during the repair, Apple will not fix it for free, and you will have to pay out of pocket. Some third-party shops will repair damage caused by a failed DIY attempt, but they charge extra.

When to replace your battery

Replace your battery when the maximum capacity drops below 80 percent, or when you notice the phone shuts down unexpectedly even though the battery percentage shows 20 or 30 percent remaining. Some people also replace the battery if they plan to keep the phone for another two or three years and want to restore performance.

If your phone is still under warranty or you have AppleCare+, do the replacement through Apple — it is free if the capacity is below 80 percent. If you are out of warranty and want to save money, a third-party shop is usually the fastest and cheapest option. Reserve DIY replacement for people who are comfortable with electronics and have done similar repairs before.

What to do with your old battery

Do not throw your old lithium battery in the trash. Lithium batteries can catch fire in landfills or recycling trucks. Apple will recycle your old battery for free if you do the replacement at an Apple Store — they take it as part of the service. If you use a third-party shop, ask whether they recycle the old battery or if you need to take it somewhere yourself.

Best Buy, Home Depot, and most municipal hazardous waste facilities accept lithium batteries for recycling at no charge. Call ahead to confirm hours and drop-off procedures. Some retailers like Best Buy also offer mail-in recycling if you do not have a location nearby.

Frequently Asked Questions

How long does an iPhone battery last?

A lithium battery is designed to retain 80 percent of its capacity after 500 full charge cycles. One full cycle is draining the battery from 100 percent to zero and charging it back to 100. In real use, this usually takes one to three years depending on how often you charge and use the phone. After that, the battery degrades gradually.

Can I replace the battery myself without voiding the warranty?

No. Any repair you do yourself voids your warranty. If you want to keep your warranty intact, use Apple's service or an Apple-authorized repair shop. Third-party shops also void the warranty, but Apple's service keeps it active.

Is a third-party battery as good as an Apple battery?

Aftermarket batteries work, but they may not last as long or hold charge as reliably as genuine Apple batteries. Some are made by the same manufacturers that supply Apple, while others are lower quality. Ask the repair shop what brand they use and read reviews before you commit.

What happens if I damage my phone while replacing the battery myself?

You will have to pay to fix the damage out of pocket. Apple will not cover it under warranty because you opened the phone. Some third-party shops will repair the damage for an additional fee, but it can cost more than the original battery replacement.

Can I use my phone while it is being repaired?

No. You will not have access to your phone while Apple or a repair shop is working on it. At an Apple Store, the process takes one to three business days. Third-party shops usually finish the same day. Plan ahead if you need your phone for work or emergencies.
