How to check iPhone original or fake

Maybe some of you are loyal to certain cell phone brands, for example, Apple’s iPhone. However, buying the latest mobile phone is sometimes too expensive, so some of you prefer to buy a second-hand phone because the price can be more affordable.

This is quite special for a used iPhone because the price is more affordable and still has a pretty good performance and still gets iOS updates from Apple. But when buying a used iPhone, you have to be careful to check whether the components in it are genuine or even KW with poor quality.

Here are tips for checking and distinguishing genuine or KW components in a used iPhone.

Pay Attention to Notifications

Since iOS 13.1 and later, Apple will warn iPhone owners who are not using genuine parts. Although this notification usually appears on the Lock Screen, you can also check in Settings > General > About.

If the iPhone doesn’t have genuine parts, there will be a warning that says, Unable to verify that this iPhone has genuine Apple [parts]. This can appear if you find an iPhone with an aftermarket or fake look.

Even on iOS 14.1 and later, iPhones with non-authorized cameras that aren’t made by Apple will say “Unable to verify that this iPhone has a genuine Apple camera.


For the screen, some OEM or KW components of the iPHone have some drawbacks. Here are its characteristics:

  • Color looks pale or whitish.
  • Poor color contrast and dynamic range.
  • Waste of battery.
  • Easily damaged and striped.
  • Touchscreen is not responsive.
  • Frequent input lag when playing games.
  • Often delays while typing.
  • Pixel density or ppi which is not as original screen.
  • The black color on the screen turns gray, the white color becomes very yellow.

The iPhone screen is known to be one of the best screens on the mobile market today. From various generations of iPhone, Apple always introduces new technology for its screen. Examples are Retina Display, Super Retina Display, Super Retina XDR, and so on.


On iPhones with original components, battery health will naturally decline with time and use. However, poor battery health can also be a sign that the iPhone is using a fake battery.

Abnormally declining battery health could be an indication that the phone is working harder to keep up with non-genuine parts. Counterfeit parts can still be used, but not good for long-term use.

In 2021, Apple released an update that allowed all iPhone models released 2018 and above to show a non-genuine battery warning. If you bought an iPhone XS, XS Max, XR, or later, you will see this warning automatically.

The warning reads, There is no verifying that this iPhone has a genuine Apple battery. Health information is not available for this battery.

Liquid Detection Indicator

Every generation of iPhone has a built-in sensor located in the SIM card slot. For older iPhone models, the search sensor is also in the headphone jack or charger connector. Most fake iPhone makers don’t include a liquid detection indicator because few people want to check it.

In general, Apple uses a white color indicator. The indicator will turn red or pink when it hits water. This indicator helps you to check whether this used iPhone has experienced water damage or not. This is quite important because water can cause corrosion.

If you find an iPhone that has water damage, it’s likely that the iPhone was repaired not from an Apple-authorized service. An Apple-certified repair center is only allowed to replace the entire device if it has been exposed to liquid, not just the parts.

CONCLUSION : Those are the tips to distinguish the original used iPhone from the fake.
