Upgradia condition descriptions

At Upgradia, we want you to shop with confidence. That is why we provide clear and honest information about the condition of every device.

Our grading system focuses solely on the cosmetic appearance of the device, so you know exactly what to expect.
All Upgradia devices are fully tested for functionality and battery health.

Warranty and returns policy

We fully stand behind the quality of our devices.
That is why every purchase includes a standard six month Upgradia Warranty and a fourteen day return period.

If you are not satisfied, you may send an email to returns@upgradia.nl including your name and order number to register your return.

Battery health

Battery performance is essential.
If the battery capacity falls below eighty percent, we replace it with a new battery.

All Upgradia devices are delivered with a minimum battery capacity of eighty percent.
The exact battery percentage is always clearly stated in the product description.

Frequently asked questions and quick solutions

In our support center you will find a clear guide that resolves common notifications and questions quickly, without stress and without the need to request a return immediately.

Important Apple notifications

When setting up your Upgradia iPhone or after an iOS update, you may see notifications such as:

“Important Battery Message”
“Unable to verify that this iPhone display is a genuine Apple part”

This means that a component has been replaced with a non Apple part, or that the replacement was performed outside an official Apple service provider.

This does not affect the functionality of the device and is not a defect.
In most cases, these notifications disappear automatically after a few days.

Unknown part

The message “Unknown Part” indicates that a component was replaced by a technician who is not authorized by Apple.

This is not a sign of a defect.
The parts used by Upgradia meet strict requirements for compatibility and quality.

Your device remains fully functional and is covered by our hardware warranty.
