Replacing an iPhone battery usually costs less than a new phone and extends the life of a working device by two to four years
A battery replacement costs between $69 and $99 at Apple, depending on your model, or $20 to $50 at third-party repair shops. A new iPhone costs $800 to $1,200. If your phone otherwise works — the screen is intact, the processor handles your apps, the camera still takes photos you want — replacing the battery is almost always the cheaper choice.
The real question is whether your phone will still be useful after the battery is fixed. An iPhone typically gets security updates for five to seven years after release. If your model is within that window and you do not need features only a newer phone offers, a battery replacement buys you real time before you have to upgrade.
If your phone is older than seven years, has a cracked screen, or the battery drains in under two hours even after a full charge cycle, the battery may not be the only problem. A technician can diagnose whether other parts are failing before you commit to the replacement.
Key Takeaways
- Battery replacement at Apple costs $69 to $99 and takes one to two hours; third-party shops often charge less but may not use Apple parts.
- If your iPhone is within five to seven years of its release date and receives security updates, a new battery extends its useful life significantly.
- Check your battery health in Settings > Battery > Battery Health & Charging to see the current capacity percentage before deciding.
- A replacement is not worth the cost if the screen is cracked, the phone is over seven years old, or other hardware is visibly damaged.
How to check if your battery is actually the problem
Go to Settings, tap Battery, then Battery Health & Charging. You will see a percentage labeled "Maximum Capacity." If it is below 80 percent, the battery is degraded. If it is below 50 percent, the phone will slow down automatically to protect the battery, and replacement will noticeably improve speed.
If the percentage is above 80 percent but the phone still drains quickly, the problem is not the battery. It may be a background app, a setting like location services running constantly, or a hardware fault in the charging circuit. A technician can test the charging port and battery separately to pinpoint the issue.
Also check how old the phone is. Open Settings > General > About and look at the "Model" line. Search "[your model] release date" to find when it shipped. If it is more than seven years old, Apple has likely stopped issuing security updates, and a battery replacement extends a phone that is already becoming unsafe to use online.
Where to replace the battery and what each option costs
Apple Stores and Apple Authorized Service Providers charge $69 for iPhone 11 and newer, $79 for iPhone X through iPhone 8, and $99 for older models. They use genuine Apple batteries, back the work with a one-year warranty, and usually complete the job in one to two hours. You can book an appointment online at apple.com/support.
Third-party repair shops like iFixit, Best Buy Geek Squad, and local independent technicians typically charge $30 to $60. Many use aftermarket batteries that work well but may not last as long as Apple parts. Some shops offer same-day service. Before choosing a shop, check reviews on Google or Yelp and ask whether they use original or third-party batteries.
Mail-in services like iFixit and Puls send a technician to your home or accept your phone by mail. They usually cost $50 to $80 and take three to five business days. This option works if no local shop is nearby, but you lose your phone during the repair.
Signs a battery replacement is not enough
If the screen is cracked or the back glass is shattered, repair costs add up quickly. Screen replacement alone runs $279 to $329 at Apple. If you are already spending that much, a new phone may be the better value.
Water damage is another red flag. If the phone has been dropped in water or exposed to moisture, the battery may not be the only component failing. Corrosion inside the phone can cause problems weeks or months after the water exposure. A technician can open the phone and inspect for corrosion before you pay for a battery replacement.
If the phone is over seven years old, check whether Apple still releases security updates for it. Visit apple.com/security/updates and search your model. If updates have stopped, the phone is no longer receiving patches for newly discovered vulnerabilities. A battery replacement extends the life of an insecure device, which is not a good trade-off.
How long a new battery actually lasts
A replacement battery degrades the same way the original did. After two to three years of daily use, capacity will drop to 80 percent again. After four to five years, it may drop below 50 percent. This is normal and not a defect in the replacement battery — it is how lithium batteries age.
The difference is that you will have already extended the phone's life by two to four years at a fraction of the cost of a new device. By the time the replacement battery degrades, your phone will likely be seven to ten years old and due for an upgrade anyway.
To slow battery degradation, avoid letting the phone drain completely, keep it out of extreme heat, and enable Optimized Battery Charging in Settings > Battery > Battery Health & Charging. This feature slows charging to 80 percent overnight and completes the final 20 percent when you wake up, which reduces stress on the battery.
When to buy a new phone instead
If your phone is three years old or newer and the battery is the only problem, replacement is the right choice. If your phone is five years old or older and you want features only a new model offers — a better camera, faster processor, or a larger screen — a new phone makes sense even if the battery still has life left.
If you use your phone for work and cannot afford downtime, a new phone eliminates the risk that an older device will fail unexpectedly. If you keep phones for ten years or longer, a battery replacement now and another in three years may still cost less than a new phone, but you are gambling that nothing else breaks.
Compare the cost of replacement plus the cost of a new phone in two to three years against the cost of a new phone now. If the total is similar, buying new today removes the uncertainty and gives you a warranty on the entire device.
Frequently Asked Questions
Does Apple replace batteries the same day?
Apple Stores and Authorized Service Providers usually complete battery replacements in one to two hours, but you should book an appointment in advance. Same-day service is not may provide if the store is busy. Third-party shops often have shorter wait times and may offer same-day service without an appointment, but call ahead to confirm.
Will a third-party battery damage my phone?
A quality third-party battery will not damage your phone. Reputable shops use batteries that meet safety standards and work with iPhone's charging system. The main difference is that third-party batteries may not last as long as Apple parts and may not be covered under Apple's warranty if something goes wrong later.
Can I replace the battery myself?
iFixit sells battery kits and repair guides for most iPhone models, and the kits cost $20 to $40. Self-repair is possible if you are comfortable opening the phone and working with small parts, but it voids any remaining warranty and risks damaging the screen or internal components if you slip. Most people are better off paying a technician.
What if my phone is still under warranty?
If your phone is less than one year old and the battery capacity is below 50 percent, Apple will replace it for free under the standard one-year warranty. If the phone is older than one year, you pay the standard replacement fee. AppleCare+ extends the warranty to two years and covers battery replacement at no cost if capacity drops below 50 percent.
How do I know if my battery is swollen?
A swollen battery pushes the back glass or screen outward, making the phone visibly warped or the screen slightly raised at the edges. If you notice this, stop using the phone and take it to a technician when ready. A swollen battery can overheat and is a safety risk. Do not attempt to replace it yourself.
