Your three main routes to a battery replacement

You can replace an iPhone battery through Apple directly, through an Apple-authorized repair shop, or by doing it yourself with a kit. Apple charges between $69 and $99 depending on your model and whether your phone is under warranty. Authorized repair shops often charge similar amounts but may have shorter wait times. DIY replacement costs $20 to $40 for a battery kit but requires opening your phone and risks damage if you make a mistake.

The route you choose depends on your comfort level with electronics, how much time you have, and whether you want a warranty on the repair. Apple and authorized shops may provide their work. A DIY repair does not, and opening your phone yourself may void any remaining manufacturer coverage.

Key Takeaways

  • Apple stores and authorized repair shops charge $69 to $99 and typically complete the repair within a few days to a week.
  • DIY battery kits cost $20 to $40 but require you to open your phone, remove the old battery, and reassemble it without damaging internal components.
  • iPhones with batteries at less than 80 percent capacity may be covered under AppleCare+ or a limited warranty, so check your coverage before paying.
  • Opening your iPhone yourself may void remaining warranty coverage, and a mistake during replacement can damage the screen, logic board, or charging port.

Getting a replacement through Apple or an authorized shop

Apple stores and Apple-authorized service providers handle battery replacements as a standard repair. You can start by visiting apple.com/repair, entering your phone model, and booking an appointment at a nearby location. You can also call an Apple Store directly or visit in person. The process usually takes three to five business days, though some locations offer same-day service if you arrive early.

Authorized repair shops — chains like Best Buy's Geek Squad, uBreakiFix, and local independent repair businesses — often complete battery replacements faster because they have less demand than Apple Stores. Call ahead to ask if they have your battery model in stock and how long the repair takes. Prices at authorized shops are typically the same as Apple's, though some may charge slightly more or less depending on location and overhead.

Before you go, check whether your phone is still under warranty or covered by AppleCare+. If your battery has degraded to less than 80 percent capacity and your phone is within one year of purchase, Apple may replace it at no cost. You can check your battery health by going to Settings > Battery > Battery Health & Charging on your iPhone.

Doing the replacement yourself with a battery kit

DIY battery kits are sold on Amazon, iFixit, and other retailers for $20 to $40. A typical kit includes a replacement battery, a pentalobe screwdriver (to open the back), plastic pry tools, tweezers, and adhesive strips to reseal the phone. Some kits also include a heat gun or hair dryer recommendation to soften the adhesive holding the battery in place.

The basic steps are: power off your phone, remove the two pentalobe screws at the bottom, heat the edges to soften the adhesive, carefully pry up the back panel, disconnect the battery connector, remove the old battery, insert the new one, reconnect the connector, and reseal the back with new adhesive. The entire process takes 30 minutes to an hour for someone with steady hands and no prior experience.

The main risks are cracking the screen while prying, damaging the battery connector or other internal components, or failing to reseal the phone properly so water gets inside. If any of these happen, repair costs can jump to $200 or more. Many people choose the professional route specifically to avoid these risks, even though the kit itself is cheaper.

What to expect during an Apple Store repair

When you arrive for your appointment, a technician will confirm your phone model and run a diagnostic to verify the battery is the problem. They will then take your phone to the back, replace the battery, and test it before returning it to you. The entire in-store time is usually 15 to 30 minutes, though you may wait longer if the store is busy.

Apple will back up your data before the repair if you ask, though they do not do this automatically. Your phone will be returned with the same iOS version and settings you had before. If your phone has a cracked screen or other damage, the technician may flag it but will still replace the battery unless you ask them to stop.

Checking your battery health before you decide

Your iPhone tracks battery health over time. Go to Settings, tap Battery, then tap Battery Health & Charging. You will see a number labeled "Maximum Capacity" — this is the percentage of the battery's original charge your phone can now hold. A new phone shows 100 percent. At 80 percent, the battery is considered degraded. At 50 percent or lower, most people notice the phone shuts down unexpectedly or drains quickly.

You will also see a section called "Condition" that says either "Normal" or "Service Recommended." If it says "Service Recommended," Apple considers the battery worn enough to replace. This does not mean your phone is broken, but it does mean a replacement will noticeably improve performance and battery life.

Warranty and coverage details

Apple's standard one-year limited warranty covers battery defects but not normal wear. If your battery capacity has dropped below 80 percent within one year of purchase and you have not physically damaged the phone, Apple will replace it for free. After one year, you pay the standard service fee.

AppleCare+ extends this coverage to two years and covers accidental damage as well. If you have AppleCare+, battery replacement is covered at no cost for the full two years, even if the battery is simply worn from normal use. You can check whether you have AppleCare+ by going to Settings > General > About and scrolling to the bottom, or by visiting apple.com/support and signing in with your Apple ID.

Frequently Asked Questions

How long does an iPhone battery last before it needs replacing?

Apple designs iPhone batteries to retain 80 percent capacity after 500 full charge cycles. In real use, this typically means two to three years before you notice a significant drop in battery life. Some people replace theirs sooner, others wait longer — it depends on how often you charge and how you use the phone.

Can I replace the battery myself without opening the phone?

No. iPhones are sealed devices, and the battery is glued inside. You must open the back panel to access it. There is no external battery door or removable component like older phones had.

Will replacing the battery fix my phone if it keeps shutting down?

Often yes, but not always. Unexpected shutdowns are usually caused by a worn battery that cannot deliver enough power under load. However, they can also be caused by a failing logic board or other hardware. A technician can run diagnostics to confirm the battery is the problem before you pay for a replacement.

What happens to my data when I get a battery replacement?

Your data stays on the phone. A battery replacement does not erase anything. Apple does not back up or restore your phone during this repair — they simply swap the battery and return it to you as it was.

Is it cheaper to replace the battery myself than to go to Apple?

The kit is cheaper upfront — $20 to $40 versus $69 to $99 — but the risk is higher. If you damage the screen, charging port, or internal components during the replacement, repair costs can exceed $200. Most people find the professional route worth the extra cost for the may provide and lower risk.
