In today’s secondary mobile market, bulk phone testing and grading is the difference between stock that just sits in a warehouse and stock that turns quickly into revenue. For the seller, the journey of each device shapes margin, speed, trust, and scalability. For the customer, it determines whether a refurbished phone really feels like a premium, reliable product.

At Cyculus, powered by Apkudo, we have built an end-to-end automated flow that connects both sides of this story. When you’re deciding where to send bulk phones for refurbishment, our model shows exactly how devices move from pallet to package – and why that matters for your business and your buyers.
The journey starts the moment bulk devices arrive at our facility near Stuttgart. Typically, these phones come from:
Firstly, we register every device into our system with a unique ID. This gives you full traceability and makes later reporting straightforward. Next, our team:
Just as importantly, we clear all residual user data as part of our controlled process, so previous owners stay protected and your brand remains trusted. This creates a clean, compliant starting point for bulk phone testing and grading.
Once prepared, devices enter the automated processing line, where robotics and AI take over. Rather than relying on inconsistent manual checks in a noisy warehouse, we run every phone through a precise, repeatable sequence of tests.
Here, the system performs:
Moreover, we capture up to 14 detailed images per device and feed them through AI-driven grading logic. This gives grading repeatability that manual inspection simply cannot match.
For sellers, this stage transforms bulk stock into clearly defined, saleable grades. You gain:
For customers, the outcome is a refurbished device whose stated grade truly matches what arrives in their hand.
Not every device with a marked or damaged screen belongs in a lower grade. Instead, intelligent restoration lets you rescue value before resale. This is where Cyculus Total Care and our partners add another layer of uplift.
When screens show light to mid-level scratches or surface scuffs, our buff and polish service, powered by Renew Kings, can make a decisive difference.
We:
As a result, devices that might have fallen into a lower grade now move up a tier, increasing average selling price across your bulk lots.
For phones with cracked glass but healthy displays, full screen replacement is expensive and can waste good components. Our screen re-glassing service, delivered by ScreenTech, offers a smarter option.
The process:
Consequently, you recover devices that look and feel like new, at a lower cost than total screen replacement. Sellers gain better margin; customers get a premium visual experience without obvious signs of repair.
The circular supply chain no longer stops at smartphones. Increasingly, buyers expect refurbished smartwatches and earbuds as well. Through our partnership with CypherBLK, we extend the same structured approach to wearables.
We support:
In addition, this means you can send mixed consignments, phones, watches, and audio devices, to one partner instead of managing separate vendors. From a seller’s perspective, this simplifies operations and creates a single model for bulk phone testing and grading plus related devices.
After testing, grading, and any selected restoration work, devices move into the final stages of the journey:
Because the entire journey runs inside one integrated flow, your team can move quickly from question, “where to send bulk phones for refurbishment?”, to answer: a single partner that prepares inventory for market with minimal friction.
