When your phone’s screen cracks, battery swells, or camera fails, you’re already in a stressful spot. The last thing you want is to walk out of a repair shop only to find out they installed low-quality parts that degrade faster, or worse, harm your device. That’s why understanding the difference between certified repair parts and generic/aftermarket replacements is more important than you think.
Whether you’re a tech enthusiast or just someone who wants reliable service, here’s what you should know before letting anyone crack open your device.
What Do “Genuine” or “Certified” Parts Mean?
“Genuine parts” refer to components made or approved by the original manufacturer (Apple, in our context). These parts match the original design, tolerances, and materials and are built to meet the same standards as the ones in your new device.
When a repair shop claims to use certified repair parts, they’re saying the parts are either OEM (Original Equipment Manufacturer) or authorised/spares that meet the original specs. These parts tend to be costlier. But there’s a reason for that.
For example, Rapid Repair states they only use genuine spare parts, and they support each repair with a lifetime warranty (except batteries, which get 1 year) to back their confidence in quality.

What Are Generic or Aftermarket Parts?
Generic or aftermarket parts are made by third parties, not by or for the original device maker. They may look similar, but they often cut corners in materials, tolerances, or testing. Sometimes they’re fine for low-impact components, but in high-precision devices like smartphones or watches, the risks add up.
You might see these come in as “cheap replacements,” “copy parts,” or even “compatible parts.” That’s where the phrase aftermarket parts risks comes into play. You’re trading price for uncertainty.
Why Genuine Parts Matter
Here are the benefits of genuine parts in a repair:
- Fit and compatibility
Genuine parts are designed for your model. They fit snugly, align correctly, and avoid misalignment or tension that can damage connectors or flex cables. - Optimal performance
You’ll get the expected brightness, battery life, sensor accuracy, signal strength, and durability. Aftermarket parts may degrade faster or never reach full capacity. - System integrity & warnings
In Apple devices, non-genuine parts can trigger warning indicators (like “Unknown part installed”) in iOS or limit certain features. Genuine parts generally avoid those flags. - Longer life & reliability
Because they use better materials and tighter manufacturing tolerances, genuine parts resist issues like corrosion, warping, or early failure. - Warranty and trust
Repair providers using genuine parts can confidently back their work with stronger warranties. Rapid Repair, for instance, offers a lifetime warranty for most parts.

The Risks of Cheap Alternatives
When shops use aftermarket or generic parts, here’s what you might face:
- Shortened lifespan: cheap adhesives, circuits, or coatings can fail sooner.
- Inconsistent performance: screen artefacts, battery swelling, or weak sensors.
- Device instability: mismatched voltage or resistance can damage surrounding components.
- No warranty: shops using budget parts often can’t stand behind their work.
- Loss of resale value: When someone inspects the device, non-genuine parts reduce your credibility and value.
That is exactly why aftermarket parts risks shouldn’t be overlooked when you compare quotes.
How to Know What Parts Are Being Used

Here’s how you can protect yourself:
- Ask the repair service explicitly whether they use genuine / OEM / certified parts. Demand clarity.
- Check warranty terms: if they offer a lifetime or strong warranty, that’s a backup indicator of quality. Rapid Repair’s terms show they provide a lifetime warranty on most parts, and a 1-year warranty on batteries.
- Request before/after photos of the part.
- Watch for system warnings after repair — some devices alert you when parts are non-genuine.
- Choose reputable repair providers who publicise their parts policy and stand behind their work.
Apple has made it quite simple to check whether your iPhone’s parts — like the battery, display, or camera — are genuine or not. Here’s a step-by-step guide:
1. Go to Settings
Open Settings → tap on General → then tap on About.
2. Look for “Parts and Service History”
If your iPhone has ever had a part replaced, you’ll see a section titled “Parts and Service History.”
This section appears only on iPhones that support part verification (explained below).
Depending on your model, you’ll see one or more of the following:
- Battery
- Display
- Camera
If all components are genuine Apple parts, it will show:
- “Genuine Apple Part”
If a part has been replaced with a non-genuine or unknown one, it will show:
- “Unknown Part”
When Generic Parts Might Be Acceptable (with Caution)
Yes, there are a few edge cases:
- Non-critical parts — buttons, simple covers, or back glass (if the function isn’t affected) may tolerate good-quality generic substitutes.
- Low-budget repairs — if your device is very old and you don’t mind reduced longevity, a cheaper solution may be better than no repair.
- Temporary fixes — to limp your phone until you can go for a high-quality repair.
But even then, know the trade-off you’re accepting.
When your device enters a repair shop, the parts they use can make or break your experience. With certified repair parts or genuine parts, you’re paying for performance, longevity, and reliability, not just a quick fix. Ignoring the aftermarket parts risks might save you a few rupees now, but can lead to bigger headaches down the line.
