With the development of the second-hand industry, more and more users are willing to try buying second-hand products. However, unlike new products, second-hand products cannot distinguish the true quality of the goods when purchased, which may lead to some second-hand products encountering some problems during use
In order to minimize pitfalls for users when purchasing second-hand products, CheChe has built a multi category testing center. Whether it is a phone or a pair of badminton rackets, they must undergo quality inspection before being put on sale.
Below, from the aspects of appearance, function, disassembly, battery, and privacy information, we will take you to understand how to choose second-hand products?
What are the appearance conditions of mobile phones that need attention?
Some mobile phones may have appearance defects such as scratches, bumps, paint peeling, and deformation after use. Due to the high requirements of the majority of users for appearance, the official verification has established professional instrument+manual verification service standards. Through 20 appearance inspections, the current appearance status of the phone case, screen, camera, card holder, etc. is disclosed.
Based on each person’s different understanding of the depth of scratches, in order to avoid cognitive bias in appearance, a 360 degree automated instrument scanning device will be used, combined with algorithm recognition to provide the length, size, and number of appearance defects. Finally, a live camera image of the machine will be provided for users to make judgments and choices.
However, for some phones with lower quality, users may be more concerned about whether defects will affect the normal use of the machine. We will use professional quality inspection tools and conduct manual inspections according to the standard procedures established by the official inspection. If there are serious scratches, scratches, paint peeling, and other problems, they are not allowed to be put on shelves for sale.
If users are dissatisfied with the product after purchase, they can enjoy the official 7-day no reason return service and shipping subsidy without affecting the resale.
How to identify potential phone functionality issues?
Some older models of mid-range and low-end smartphones may experience functional aging or hidden issues as usage time increases. To help users troubleshoot such issues, the official verification service will conduct over 50 functional tests on the phone, including screen touch, buttons, camera, biometric recognition, wireless connection, etc.
Screen display and touch issues: Use professional testing tools to troubleshoot whether there are bright spots, bad spots, and other issues on the screen; Touch the screen with your fingers to see if there is any screen skipping disorder, local failure, or indirect failure.
Button issue: Press the button with your fingers repeatedly for 3 times, check if the device has feedback, if the elasticity is good, and check if there are any dents, paint peeling, or other issues on the appearance
Camera issues: Take photos to check for all black, flicker, cracks or bad spots in the captured image display; Check for spots and clear shooting through a solid color background.
Restart and blue screen issues: These are a type of hidden disease problem that is difficult to reproduce. Therefore, the official verification team has independently developed a performance testing tool, which not only reads abnormal underlying data in daily use, but also continuously imitates high-intensity usage scenarios for pressure testing to improve the recurrence rate of hidden diseases. If such problems are found, they are not allowed to be put on the shelves for sale.
Any abnormal issues discovered during functional testing, regardless of whether they affect usage, will be disclosed in the quality inspection report. However, the problem of hidden diseases in mobile phones is random and cannot be detected 100% in daily testing. If users discover problems that are not disclosed in the quality inspection report after purchasing the machine, they can enjoy official inspection and return or warranty services. Please refer to the product details for details.
How to determine the issue of mobile phone disassembly/immersion?
Some users may worry about buying privately repaired or soaked phones, which may affect the performance and lifespan of the machine. In order to help users trade with confidence, the official product inspection will require testing of components such as the screen, body, camera, motherboard, etc., in order to minimize the problem of disassembly/immersion.
How to troubleshoot whether the machine has been disassembled or repaired?
Some mobile phones will connect to system tools for comparison and verification with factory information; If there is a history of repair or replacement, it will be truthfully disclosed in the quality inspection report. But some of the tests may be third-party repairs, and the official cannot conduct the tests.
Check for glue overflow, pry marks, and foreign objects at the gaps on the appearance of the phone to identify whether the device has been refurbished/repaired.
For equipment with dismantling capabilities, we will dismantle and inspect internal parts such as screws, motherboards, and cables, and disclose maintenance and replacement information.
How to troubleshoot whether the machine has immersion problems?
Check the appearance of the machine for screen immersion, rust on screws, water ingress into the camera, etc., to determine if the equipment has any issues with excessive immersion.
For machines with immersion risks, the machine will be disassembled to check if the waterproof label inside the body has turned red, and if there are signs of rust, mold, water stains, etc. on the components to disclose the immersion situation.
After inspection, machines with official repair records of the brand will be disclosed in the quality inspection report. Non official repair or immersion machines will be notified and returned to the seller.
How to diagnose the battery life of a mobile phone?
From the current industry technology perspective, the detection ability of mobile phone battery life has always been a major challenge in the second-hand market, and the actual battery health status of most mobile phones in the market cannot be detected. To alleviate this problem, we have invested millions of funds to establish an official battery health testing team and service standards.
Reading basic battery information: Some mobile phones can use tools to read official channel charging cycle times, health status and other data to preliminarily determine the battery condition.
Restore the real power consumption situation: All phones will simulate high-intensity usage scenarios, accurately capture the total power consumption and compare it with the average power consumption of the model while playing audio and video continuously for 30 minutes. Devices judged as abnormal power consumption are not allowed to be sold.
For some Apple phones with good quality but low battery health value, in order to adhere to the concept of environmental protection and sustainable recycling, we will replace certified and legitimate brand batteries (such as Hanke, Huayanku, Haisi, Pinsheng, etc.) to ensure the phone’s battery life, and disclose it in the quality inspection report. The maximum capacity of the battery is the same as the original battery, so you can choose with confidence.
Mobile phones, privacy issues cannot be ignored
01 Privacy Clearing, Protecting User Information Security
With the increasing number of user information bound to various software on mobile phones, the risk of privacy leakage has become a concern for users.
Therefore, CheChe has officially established a highly systematic privacy clearance capability. Being able to clear user data and restore the device to its factory settings not only protects the privacy of the original user, but also strives to ensure that the device reaches a clean data state before sale.
It is worth mentioning that the official privacy verification and clearance technology has obtained Adisa International Authoritative Data/Privacy Security Certification, providing a solid foundation for our future continuous improvement and innovation.
02 Intelligent device for comprehensive cleaning of mobile phones
While ensuring the integrity of the equipment, comprehensive cleaning is carried out through intelligent devices, including surface cleaning of screens, casings, cameras, and other surfaces, as well as deep cleaning of detailed parts such as interfaces, card slots, and earphones, allowing users to obtain a clean and tidy phone.
After quality inspection, the products will be sent to unmanned cabinets for classification and storage under robot automation. After receiving the user’s order information, the official inspection products will be delivered to the user’s hands through DHL, UPS, and free shipping services.
