Yes, you can replace an iPhone battery, but the method depends on your model and comfort level

Apple designs most iPhones so the battery is not user-replaceable without opening the device. You have three real options: take it to Apple or an authorized repair shop and pay for a replacement, use a third-party repair service, or open the phone yourself if you have the tools and patience. Which route makes sense depends on your iPhone model, how old it is, and whether you want to keep your warranty intact.

The battery in your iPhone degrades over time. After about 500 full charge cycles — roughly one to two years of normal use — most iPhone batteries hold noticeably less charge. Apple considers a battery degraded when it holds less than 80 percent of its original capacity. You can check your battery's health in Settings by going to Battery, then Battery Health & Charging.

Key Takeaways

  • Apple will replace your battery for a set fee (usually $69 to $99 depending on model), and this keeps your warranty valid.
  • Third-party repair shops often charge less than Apple but may use non-original parts, which can affect performance or future repairs.
  • Opening your iPhone yourself voids the warranty and risks damaging the screen, logic board, or water seals if you make a mistake.
  • Your iPhone model matters: newer iPhones with Taptic Engine and Face ID are harder to open safely than older models.
  • If your phone is still under warranty or AppleCare+, battery replacement may be covered at no cost if the battery is defective.

Taking your iPhone to Apple or an authorized repair shop

This is the safest route for most people. Apple charges a flat fee for battery replacement — typically $69 for older models and $99 for newer ones — and the work comes with a 90-day warranty on the repair itself. You keep your device warranty intact, and Apple uses genuine parts. You can book an appointment at apple.com or in the Apple Support app, or walk into an Apple Store and ask about same-day service (availability varies by location).

If your iPhone is under warranty or you have AppleCare+, the battery replacement is free if the battery is genuinely defective — meaning it holds less than 80 percent capacity and you have not physically damaged the phone. AppleCare+ also covers accidental damage, so if your battery failed because of water damage or a drop, AppleCare+ covers the replacement at no cost. Without coverage, you pay the standard fee.

Authorized Apple repair shops (not all phone repair shops are authorized) follow the same pricing and warranty rules. You can find one near you through apple.com by searching "Find Locations" and filtering for service providers. The repair usually takes one to three hours, though some locations offer mail-in service if you are not near a store.

Using a third-party repair service

Independent phone repair shops often charge $30 to $60 for battery replacement, less than Apple's fee. The trade-off is that they may use aftermarket batteries instead of genuine Apple parts. An aftermarket battery works, but it may not hold charge as long, and it can trigger a "Unable to Verify" message in your Settings that warns the battery is not genuine. This message does not mean the battery is unsafe — it is Apple's way of flagging non-original parts.

Before you choose a third-party shop, ask whether they use original or aftermarket batteries and what warranty they offer on the repair. Some shops source genuine parts from salvaged phones, which is cheaper than buying from Apple but still original. Others use new aftermarket batteries. Neither is inherently bad, but you should know which you are getting.

A third-party repair also voids any remaining manufacturer warranty on your phone, though the repair itself usually comes with a 30 to 90-day warranty from the shop. If something goes wrong with the battery after that period, you are responsible. Check reviews on Google Maps or Yelp before you go — a shop with consistent complaints about battery failures is a sign to look elsewhere.

Opening your iPhone yourself

If you want to replace the battery yourself, you will need a pentalobe screwdriver (the five-pointed star tool Apple uses), a plastic spudger or opening pick, tweezers, and a heat gun or hair dryer. iFixit sells battery replacement kits with tools and a genuine or high-quality aftermarket battery for $20 to $40, depending on your model. YouTube has detailed video guides for almost every iPhone model.

The process is different for each model. Older iPhones (iPhone 6s and earlier) are easier to open because the battery is held in with straightforward adhesive strips. Newer models have more complex internal layouts, and the battery is glued in place more aggressively. iPhone 14 and newer models have additional complications because of the Taptic Engine and other components packed tightly around the battery.

The biggest risks are damaging the screen (which is glued to the frame and can crack if you pry too hard), breaking the water-resistance seals, or disconnecting a ribbon cable that connects the battery to the logic board. If any of these happen, you are looking at a much more expensive repair or a broken phone. This is why opening your iPhone yourself voids your warranty — Apple will not repair damage you cause during a DIY battery replacement.

What to expect during battery replacement

Whether you go to Apple, a third-party shop, or do it yourself, the process takes similar steps. The technician or you will power off the phone, remove the bottom screws (or open the screen), disconnect the battery connector, remove the old battery, install the new one, and reconnect everything. The entire job usually takes 30 minutes to an hour if you know what you are doing.

After replacement, the phone should show 100 percent battery capacity in Settings under Battery Health. If it shows less than 100 percent right away, the battery may be defective or used. A new battery should always show 100 percent initially. If you used a third-party service and the battery shows "Unable to Verify," that is normal for aftermarket parts and does not affect performance.

When to replace your battery versus replacing your phone

If your iPhone is more than four or five years old and the battery is degraded, you might be close to the end of the phone's useful life anyway. Older phones also run slower as the operating system gets heavier with each update. A new battery costs $69 to $99, but a new phone costs $400 to $1,200. If your phone is still fast enough for what you do, a battery replacement makes sense. If it is slow, the screen is cracked, or the camera is failing, replacing the phone might be the better choice.

Apple's trade-in program lets you send in your old iPhone and get credit toward a new one, which can offset some of the cost. You can check your phone's trade-in value at apple.com. If your phone is worth $100 to $300 in trade-in credit, that might make a new phone more affordable than you think.

Frequently Asked Questions

How do I know if my battery needs replacing?

Go to Settings, tap Battery, then Battery Health & Charging. If the maximum capacity is below 80 percent, your battery is degraded and will not hold a full charge as long as it used to. You can also look for signs like the phone shutting down unexpectedly at 20 or 30 percent battery, or needing to charge multiple times a day.

Will Apple replace my battery for free?

Only if your phone is under warranty or you have AppleCare+ and the battery is genuinely defective (not damaged by water, drops, or physical harm). Otherwise, you pay the standard fee. If your phone is out of warranty and you do not have AppleCare+, the cost is usually $69 to $99.

Can I use my iPhone while the battery is being replaced?

No. The phone must be powered off and opened to access the battery. At Apple, the process takes one to three hours. At a third-party shop, it usually takes 30 minutes to an hour. You will not have your phone during that time.

What happens if I replace the battery myself and something breaks?

Apple will not repair damage you cause during a DIY replacement under warranty. If you damage the screen, logic board, or water seals, you will have to pay for those repairs separately. This is why most people choose to have a professional do it.

Is an aftermarket battery safe?

Yes, aftermarket batteries from reputable shops are safe. They work and hold a charge, though they may not last quite as long as a genuine Apple battery. The "Unable to Verify" message in Settings is just Apple flagging that the part is not original — it does not mean the battery is dangerous.
