Not sure if your iPhone battery is original or has been swapped? The serial number and battery info can help you find out.
To check if your iPhone battery is original, look for system warnings in Settings, review battery health, or use diagnostics tools that read serial numbers.
Let’s go over every method—no tools, no confusion—and explain what your iPhone is really telling you.
How to check if your iPhone battery is original?
If you've had a repair done or bought a second-hand phone, you might wonder if the battery inside is genuine.
You can check if your iPhone battery is original by going to Settings > General > About > Parts and Service History (on iPhone XR or later).
What you might see:
- ✅ “Genuine Apple Part” – The battery is original and installed by Apple or an authorized service provider.
- ⚠️ “Unknown Part” – The battery was replaced by a third party or is not recognized as genuine.
- 🚫 No info available – May indicate older model, non-supported iOS, or damage to internal records.
| Message Shown | What It Means |
|---|---|
| Genuine Apple Part | Battery installed by Apple |
| Unknown Part | Non-original or unverified battery |
| No Service Info | Not replaced, or system unable to detect |
Bonus tip:
Newer iPhones (iPhone 11 and up) will also show a service message under Settings > Battery > Battery Health & Charging if the battery is not genuine.
How to check battery serial number on iPhone?
The iPhone doesn’t show the battery serial number directly in Settings—but you can still get it.
To check the battery serial number, connect your iPhone to a computer and use a third-party diagnostic tool like 3uTools (Windows) or CoconutBattery (Mac).
Here’s how to do it:
Using 3uTools (Windows):
- Download and install 3uTools.
- Connect your iPhone to your PC via USB.
- Go to the “Battery Life” tab.
- Look for:
- Battery Serial Number
- Battery Manufacturer
- Cycle Count
- Battery Manufacture Date
Using CoconutBattery (Mac):
- Install CoconutBattery.
- Connect your iPhone.
- Click on the “iOS Device” tab.
- You’ll see similar battery data including serial number and full charge capacity.
These tools are especially useful for refurbishers, resellers, and tech-savvy users who want to verify the authenticity of the battery.
| Data Field | What It Tells You |
|---|---|
| Serial Number | Unique ID of the battery |
| Design Capacity | Original full capacity (e.g., 3,110 mAh) |
| Full Charge Capacity | Current maximum capacity |
| Cycle Count | Number of full charge cycles |
| Manufacture Date | When the battery was made |
If the serial number is blank, invalid, or doesn't match Apple’s battery format, it’s likely a third-party battery.
How to check iPhone battery health with serial number?
While the serial number confirms identity, what you really want to know is: How healthy is this battery?
You can check battery health more precisely using diagnostic software that shows the serial number, cycle count, and design capacity together.
Serial number alone doesn’t tell you the health. Instead, focus on:
- Cycle Count – How many full charge-discharge cycles the battery has gone through.
- Design vs Full Capacity – Compare what the battery should hold vs. what it actually holds.
- Battery Age – A newer battery (based on manufacture date) is likely in better condition.
Ideal values:
| Metric | Healthy Range |
|---|---|
| Cycle Count | Under 500 cycles (ideal under 300) |
| Full Charge Capacity | 90%+ of design capacity |
| Age | Under 18–24 months |
| Serial Present | Matches format of Apple battery numbers |
In my wholesale business, we scan every battery and screen component using these methods before shipping. We verify the serial, cycle count, and make sure it passes voltage and safety tests. That’s how we keep defect rates low.
If you’re buying or refurbishing iPhones, learning how to read this info is essential for quality control.
Conclusion
You can’t see the battery serial number in iPhone Settings, but with tools like 3uTools or CoconutBattery, you can check if the battery is original, how many cycles it’s gone through, and whether it’s worth replacing.
