1, view the mobile phone manual In the specification parameters of the manual, there will be related to mobile phone wireless chargingIntroduced. If the phone supports wireless charging, it will be clearly explained in the manual. View Phone Settings In your phone's Settings, you can find options such as battery or wireless and networking. If the phone supports wireless charging, it will usually provide Settings for wireless charging in these options.
2, check the phone's manual If you are not sure whether your phone supports wireless charging, you can check the phone's manual. In the specification parameters of the manual, there will be a relevant introduction to wireless charging. If your phone supports wireless charging, this will be clearly stated in the manual. Check the phone's Settings if you have already purchased itMobile phone, but do not know whether to support wireless charging, you can check through the phone's Settings.
3, 1: Test with wireless charger This is the most simple and direct method, put the phone on the wireless charger, if the charging is displayed, it means that the wireless charging function is not supported. This test is because the current wireless charging mobile phones and chargers on the market are compatible with the QI protocol, and can be charged immediately.
4, to see whether the mobile phone has wireless charging function, the most direct way is to check the product specification table or user manual of the mobile phone, or find the relevant information in the mobile phone Settings. First of all,Decide which phone you want to test.
Therefore, in the test must consider the charger, interface line and battery three aspects of the match, in order to ensure the accuracy of the charging efficiency. Next, the fast charging efficiency of different mobile phones is evaluated through a test device with a charge control chip. Test equipment will record the battery voltage, current, charging time, charging speed and other key data of each mobile phone, and then comprehensively calculate the charging efficiency of each mobile phone.
In the horizontal evaluation, we use the following three methods to evaluate. Standby test The standby test evaluates the phone batteryOne of the most basic tests of performance. The test requires the phone to keep the screen on and perform various application tests to measure the phone's power management performance, such as standby time and battery consumption. For the standby test, we used a test program during the test and set the brightness of the phone to the same standard value.
First of all, the battery loss test of the mobile phone is completed by simulating the user's use scenario. Testers will use the phone for a certain period of time for different operations, including music, video, games, etc., to test the wear and tear of the phone in different scenarios. At the same time, there are examsConsider various network environments, such as 4G, 5G, WIFI, etc., in order to test the battery consumption under different networks.
1, Qi certification test process includes a number of specific standards and stringent requirements, covering safety, interoperability and energy efficiency testing, to ensure that each device and charger work together, compatible with multiple devices. This process also includes member registration, Logo license agreement signing, product registration, information filling, Logo authorization review, test implementationMultiple steps, including interoperability verification, product information revision and final audit, are eventually incorporated into WPC's product database.
2, apply for Qi certification to provide 5 samples, at least 3 sets of test AIDS, product instructions and operating instructions, self-declaration form. The certification process is carried out by a professional QI certification agency, such as Beijian New Energy, which has CNAS/CMA qualification and provides a full range of one-stop services from certification application to product registration to help customers easily obtain a pass to enter the multinational market, cost-effective and faster cycle.
3, Qi certification scoreThere are three types: - Qi-BPP certification: The product supports less than 5W power, uses the Qi protocol, and must pass the BPP certification. - QI-EPP certification: The product supports more than 5W power. If the Qi protocol is used, the product must pass EPP certification. - Qi-PPDE Certification: Products support more than 5W power, use Samsung private protocol PPDE, must be tested by PPDE (implemented from July 1, 2019).
4, wireless charging Qi certification test content includes Compliance test (Compliance test) and compatibility test (Interoperability Test). The compliance Test was conducted by the Authorized Test Lab (ATL) with 5 samples.
5, Qi certification: the universal language of Wireless charging industry Qi, the full name of the wireless charging Alliance (Wireless Power Consortium, referred to as WPC) masterpiece, it defines a global universal wireless charging standard. This standard takes "convenience" and "versatility" as the core, ensuring that different brands of products only need to have the Qi logo, which can be used with the QI logoAny QI-compatible wireless charger works seamlessly.
6, Qi certification testing content detailed Qi certification testing content is rigorous and comprehensive, mainly including: transmitter and receiver communication protocol: to ensure that both sides can quickly and accurately exchange data. Power output and stability: In the XYZ axis translation test, verify the wireless charging capability of the device at different angles. Energy transmission limit: Test the maximum power supply capacity of the equipment to ensure safety performance.
When conducting wireless charging efficiency tests, Wireless charging Test Standard Method We need several main tools and equipment. The first is a wireless charging pad for testing, which needs to be able to support all the major charging protocols, such as Qi, AirFuel, and PMA. In addition, an ammeter is required, and its main function is to test the current consumed by the wireless charging pad when charging. When testing, we need to first decide which phone to test.
Products that pass these two tests ensure a safe and reliable wireless charging experience. The testing process for Qi certification includes a number of specific standards and stringent requirements covering security, interoperability andEnergy efficiency testing ensures that each device and charger works together and is compatible with multiple devices.
The test environment was selected Millet Home, and the equipment used was the specially modified Millet 10 Pro, whose battery capacity was reduced from 4500mAh to 4000mAh, but the wireless fast charge was upgraded to 40W. The test starts from 1% power, during the charging process, the voltage and current are stable at 17V and 4A, and the power is always maintained at 40W, although wireless charging will have some efficiency loss, but in line with the official data.
