Yes, iPhone batteries can be replaced, but where and how you do it matters
Your iPhone battery can be replaced. Apple replaces them at its stores and authorized repair shops. Third-party repair shops also replace them, often faster and cheaper. The catch is that doing it yourself voids your warranty, and using an unauthorized shop may mean losing water resistance or getting a battery that doesn't hold a full charge.
The real question is not whether replacement is possible, but which route makes sense for your situation — how much you want to spend, how quickly you need it done, and whether you want to keep your warranty intact.
Key Takeaways
- Apple and authorized repair shops replace batteries under warranty if your phone is less than a year old and the battery health has dropped below 80 percent.
- Out-of-warranty replacements at Apple cost between $50 and $80 depending on your iPhone model, and take one to three days.
- Third-party repair shops typically charge $30 to $60 and can often replace a battery the same day, but may not use genuine Apple parts.
- Replacing the battery yourself using a kit voids your warranty and risks damaging the screen, logic board, or water sealing.
- You can check your battery health in Settings > Battery > Battery Health & Charging to see if replacement is actually necessary.
Apple's battery replacement program and warranty coverage
If your iPhone is less than a year old and the battery health has dropped below 80 percent, Apple replaces it free under the standard one-year limited warranty. You can check your battery health by going to Settings, tapping Battery, then Battery Health & Charging. The percentage shown is how much capacity your battery retains compared to when it was new.
Once your phone is out of warranty, Apple charges a flat fee for battery replacement. The cost depends on your model: older iPhones like the iPhone 11 cost around $50, while newer models like the iPhone 15 cost around $80. Apple uses genuine parts and maintains water resistance after replacement. The process typically takes one to three business days, though some stores offer same-day service if you arrive early.
To start a replacement at Apple, visit apple.com/support, select your device, choose Battery Service, and book an appointment at your nearest Apple Store or Apple Authorized Service Provider. You can also walk into a store and ask, though appointments usually move faster.
Third-party repair shops and what to expect
Independent phone repair shops replace iPhone batteries for $30 to $60, depending on the model and your location. Many can do the work the same day or within a few hours. The trade-off is that these shops may use aftermarket batteries instead of genuine Apple parts, and the replacement may not restore full water resistance.
Before choosing a third-party shop, ask whether they use original Apple batteries or third-party replacements. Original parts cost more but perform better and last longer. Ask also whether they warranty the battery — most reputable shops offer a six-month to one-year warranty on the replacement battery itself.
Find a shop by searching "iPhone battery replacement near me" or asking for recommendations in local community groups. Check Google reviews and look for shops that have been in business for at least a few years. Avoid the cheapest option if the shop has no reviews or a history of complaints about battery quality.
DIY battery replacement kits and why they carry real risks
Battery replacement kits are sold online for $20 to $40 and include the battery, adhesive strips, and tools. Replacing the battery yourself voids your warranty when ready. More importantly, the process is genuinely difficult and carries a high risk of damage.
Opening an iPhone requires heating the edges to soften the adhesive, then prying carefully to avoid cracking the screen. The battery itself is glued down and must be pried out slowly to avoid puncturing it — a punctured lithium battery can catch fire. Once the old battery is out, you must remove the adhesive completely and explore new adhesive strips before installing the new battery, then seal the phone back together.
If you slip with the pry tool, you can crack the screen (a $200+ repair). If you damage the logic board, the phone may not turn on. If you don't seal it properly, water will get inside and corrode the components. Most people who attempt this end up paying more for repairs than they would have paid for a professional replacement.
When battery replacement is actually worth doing
Replace your battery if the health percentage in Settings drops below 80 percent and you notice the phone shutting down unexpectedly, draining quickly even when you're not using it heavily, or struggling to run demanding apps. A battery at 50 percent health or lower will make the phone feel noticeably slower because iOS throttles performance to prevent shutdowns.
If your phone is still under warranty and the health is below 80 percent, get the replacement from Apple for free. If it's out of warranty and the phone is less than three years old, a $50 to $80 replacement at Apple is usually worth it — you get a genuine part, water resistance is maintained, and your warranty is not affected. If the phone is older than four years, consider whether you plan to keep it another year or two; if you're planning to upgrade soon, the replacement may not be worth the cost.
What happens to your data during battery replacement
Your data stays on the phone during battery replacement. The technician removes the battery but does not erase the storage, so all your photos, messages, apps, and settings remain exactly as they were. You do not need to back up before the appointment, though it never hurts to have a recent backup just in case.
After the replacement, your phone will work normally. The battery health will show 100 percent if it's a new genuine battery, or sometimes 99 percent depending on the testing conditions. You may notice the phone feels slightly faster because iOS is no longer throttling performance to protect an aging battery.
Comparing the three routes side by side
| Route | Cost | Speed | Warranty Impact | Battery Quality |
|---|---|---|---|---|
| Apple Store or Authorized Shop | Free if under warranty; $50–$80 if out of warranty | 1–3 business days | No impact; warranty continues | Genuine Apple battery; full water resistance maintained |
| Third-Party Repair Shop | $30–$60 | Same day or next day | Warranty voided for battery and water resistance | May be aftermarket; water resistance may be reduced |
| DIY Kit | $20–$40 plus tools | 2–4 hours (if successful) | Warranty voided; risk of additional damage | Aftermarket battery; high risk of installation damage |
Frequently Asked Questions
How do I know if my battery actually needs replacing?
Go to Settings, tap Battery, then Battery Health & Charging. If the percentage is 80 percent or higher and your phone is not shutting down unexpectedly or draining unusually fast, the battery is fine. If it's below 80 percent and you notice performance issues or unexpected shutdowns, replacement will help.
Will Apple replace my battery if I cracked the screen?
Apple will replace the battery even if the screen is cracked, but they may ask you to repair the screen first if the damage is severe enough to make the battery replacement risky. Ask when you book the appointment. Some shops will do both at once; others will do the battery first and let you decide about the screen separately.
Can I use my phone while the battery is being replaced?
No. The technician needs to power off the phone, remove the battery, and install the new one. The process takes 30 minutes to an hour at Apple. You can use the phone again as soon as the replacement is done.
What if the replacement battery dies quickly?
Apple batteries come with the remainder of your phone's warranty, so if a battery fails within that period, Apple will replace it again at no cost. Third-party shops usually warranty their batteries for six months to one year, so contact them if the battery fails during that window and they will replace it.
Is it cheaper to buy a new phone than replace the battery?
Almost never. A used iPhone in good condition costs $200 to $500 depending on the model. A battery replacement costs $50 to $80. Even if you replace the battery twice, you spend less than $200, which is still far less than a new phone. Battery replacement only makes sense to skip if your phone is already four or five years old and you were planning to upgrade anyway.
