One of the most common questions we hear is:
“Do I really need original parts, or is generic fine?”
After repairing thousands of phones, the honest truth is this:
the OEM vs generic debate is not black and white.
Some generic products are excellent value. Others are the reason phones fail, overheat, or come back for repeat repairs.
This guide explains when quality is critical, where you can safely save money, and how to avoid the false economy of cheap accessories.
These terms are often misused, so let’s clarify them simply:
Original / OEM (Genuine)
Parts made by the phone manufacturer or their authorised factory, built to exact specifications. Highest compatibility, highest cost.
Certified / Licensed Third-Party
Trusted brands that meet recognised safety and performance standards. Often the best balance of quality and value.
Compatible / High-Quality Aftermarket
Well-made alternatives designed to work properly with your phone, without official branding.
Generic / Unbranded
Low-cost products with varying quality. Some are fine, many are poorly made.
Counterfeit (Avoid Completely)
Illegal copies made to look original. These lack safety testing and can damage your phone or cause serious hazards.
Refurbished Original
Genuine original parts recovered from devices, tested and reused. Often the best option for screens, offering original quality at a lower cost.
From a repair perspective, accessories and parts fall into three clear risk levels.
Always choose Original or High-Quality Certified
These components handle power or contain lithium cells. Poor quality here can be dangerous.
Includes:
Internal phone batteries
Wall chargers / power adapters
Power banks
What we see when quality is poor:
Overheating
Battery swelling
Phone not charging properly
Damage to charging circuits
For these items, saving money upfront often leads to costly repairs later.

Choose Refurbished Original or High-Grade Compatible
These won’t usually cause safety issues, but they strongly affect daily use.
Includes:
Display screens & touch panels
Camera modules
Speakers and microphones
Low-quality versions often cause:
Ghost touch
Dull colours or low brightness
Poor call or camera performance
For premium phones, refurbished original screens often give the best results.

Generic is usually fine
These products are simple and standardised.
Includes:
Screen protectors
Phone pouches
Basic cases
Cleaning accessories
Here, fit and basic quality matter more than branding.

A very common mistake we see is buying the cheapest option available.
Examples:
A cheap cable that fails every few months
A low-quality charger that slowly damages the battery
A fake high-capacity power bank that performs poorly
What looks cheap today often becomes more expensive over time, especially when it leads to repairs.
Simple rule:
If a deal looks unrealistically cheap, quality has almost certainly been sacrificed.
Instead of focusing only on price, check for:
Clear safety markings on electrical products
Proper fast-charging support
Reputable brand reputation
Realistic capacity claims (especially power banks)
These indicators help avoid unsafe or short-lived products.
Myth: “Original is always the best.”
Reality: Some third-party brands outperform basic original accessories.
Myth: “All generic parts are bad.”
Reality: The problem is cheap and untested, not generic.
Myth: “A charger can’t damage my phone.”
Reality: Poor power regulation is a leading cause of charging and battery faults.

Protection depends on design
From repair experience:
Low-quality parts fail sooner
Some repeat faults are caused by accessories, not the phone
Repair lifespan depends heavily on part quality
Choosing the right quality protects your phone and your repair investment.
Generic doesn’t mean bad.
Original doesn’t mean always necessary.
What matters is knowing where quality is critical — and where it isn’t.
If you’re unsure, ask before buying.
It’s far cheaper than repairing avoidable damage later.
