How to know if iPhone battery is changed or original?

You paid for a battery replacement, but how can you be sure the job was done—or that the battery is even genuine?

You can check if your iPhone battery has been changed or is original by using Settings, checking service history, or running diagnostics.

Let me walk you through all the ways to tell if your iPhone battery was replaced, and whether it’s an original or a third-party unit.

How can I know if my iPhone’s battery was actually replaced?

After a battery swap, you might wonder—was the part really changed, or did the shop just say so?

Go to Settings > General > About > Parts and Service History. If the battery was replaced, it will show up there.

Here’s what you’ll see:

• “Battery” listed under Parts and Service History = battery was replaced.
• “Unknown part” warning = battery replaced with non-genuine part.
• Nothing listed = battery is still original (or running iOS that doesn’t support this feature).

Which models support this feature?

If you don’t see this section, try checking in Settings > Battery > Battery Health & Charging. Sometimes iOS will also show messages like:

• “Unable to verify this iPhone has a genuine Apple battery.”
• “Battery health information not available.”

That’s a strong sign the battery has been replaced with a third-party part.

How will I know if my iPhone battery is original?

Not all batteries are the same—even if they fit your phone. Original Apple batteries follow strict safety and performance standards.

If your iPhone doesn’t show warnings and displays battery health normally, it's likely using an original or Apple-authorized battery.

Look for:

• ✅ No warning under Battery Health
• ✅ “Maximum Capacity” and “Peak Performance” sections show normally
• ✅ No “Unknown Part” under Service History

In my wholesale parts business, we always clarify if the battery is original, OEM, or high-copy, because it directly affects performance, compatibility, and even resale value.

How do you know if a battery is original?

There are ways to tell if a battery is original—even without opening the phone.

An original battery will show up correctly in system diagnostics and will not trigger any iOS warnings. A fake or cheap battery might cause alerts or incorrect health readings.

If you’re able to physically inspect the battery (after opening the phone), check:

What to look for:

Software Check:

• Use tools like 3uTools (on Windows) to run diagnostics when connected via USB.
• Check for serial numbers, cycle counts, and battery manufacturing date.

We often test batteries in bulk using software tools to confirm the batch quality and compatibility. Genuine batteries will have detailed metadata. Fakes often show “N/A” for important info like cycle count or manufacturer.

How to check new iPhone battery?

After getting a new battery installed, make sure it’s working properly.

To check a new iPhone battery, go to Settings > Battery > Battery Health & Charging and confirm that Maximum Capacity is 100%.

You should also test:

• Charging time: New batteries charge faster and hold charge longer.
• Heat levels: If the phone gets hot during light use, the battery might be low quality.
• Drain speed: A proper battery should last at least 6–8 hours of normal use.

What you should see in Settings:

If anything looks off, go back to your repair center. High-quality batteries usually come with a warranty (6–12 months)—especially if you sourced it from a certified wholesale supplier like us.

Conclusion

You can check if your iPhone battery was changed by looking under Service History and Battery Health. No warning messages and 100% capacity? You likely got a good replacement.
