Genuine vs Aftermarket Parts: An Honest Comparison
One of the most common questions we get: "Should I use genuine or aftermarket parts?" The honest answer: it depends. Here's our unbiased guide to help you decide.
Understanding Your Options
Genuine/OEM Parts
Definition: Parts manufactured by or for the original device manufacturer (Apple, Samsung, etc.)
Sources:
- Directly from manufacturer repair programs
- Authorised service provider channels
- Pulled from donor devices (recycled genuine)
Aftermarket Parts
Definition: Parts manufactured by third parties to fit original devices
Quality tiers:
- Premium aftermarket - High-quality, meets or exceeds OEM specs
- Standard aftermarket - Good quality, minor compromises
- Budget aftermarket - Functional but lower quality
Part-by-Part Comparison
Screens/Displays
Genuine Screens:
✓ Exact colour matching to original ✓ True Tone/colour calibration compatible (Apple) ✓ Identical touch response ✓ Full brightness and contrast ✓ Official warranty coverage
✗ Most expensive option ✗ May still require calibration ✗ Limited availability for older models
Aftermarket Screens:
✓ Significantly lower cost (40-60% savings) ✓ Good quality options available ✓ Wider availability ✓ Often identical function
✗ Colour may vary slightly ✗ True Tone may require programming ✗ Brightness can be lower (check specs) ✗ Longevity varies by manufacturer
Our recommendation:
- iPhone 13+/MacBook Pro: Genuine preferred (quality gap noticeable)
- iPhone 8-12: Premium aftermarket often excellent
- Older models: Aftermarket usually best value
Batteries
Genuine Batteries:
✓ Guaranteed capacity match ✓ Apple/Samsung health monitoring works fully ✓ Consistent charging behaviour ✓ Certified safety standards
✗ Expensive ✗ No battery service warning displayed (Apple) ✗ May require diagnostic to clear warnings
Aftermarket Batteries:
✓ Much lower cost (50-70% savings) ✓ Good capacity from quality suppliers ✓ Functions identically day-to-day
✗ Capacity may vary (spec ≠ actual sometimes) ✗ Will show service message on iPhone ✗ Unknown longevity (new products) ✗ Safety certification varies
Our recommendation:
- Safety-critical (phones, laptops): Genuine or premium aftermarket only
- Always verify supplier certifications
- Never compromise on battery safety
Cost Comparison Example
iPhone 14 Screen Replacement
| Part Type | Part Cost | Our Price | Notes |
| Genuine Apple | £200+ | £249 | Full Apple quality |
| Premium Aftermarket | £80 | £149 | High quality, slight colour variance |
| Standard Aftermarket | £50 | £99 | Good quality, some compromises |
Our Honest Recommendations
Choose Genuine When:
- Device is new (under 2 years)
- Critical components
- You're particular about quality
Choose Quality Aftermarket When:
- Device is older (3+ years)
- Budget is a factor

Conclusion: It's Not Black and White
The "genuine is always better" narrative isn't entirely true. Neither is "aftermarket is just as good."
Reality:
- Genuine parts are consistent but expensive
- Quality aftermarket is often excellent value
- Cheap aftermarket is false economy
- The right choice depends on your device, budget, and priorities
