2, therefore, in the test must consider the charger, interface line and battery three aspects of the match, in order to ensure the accuracy of 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.
3, horizontal evaluationWe used the following three methods for evaluation. Standby test Standby test is one of the most basic tests to evaluate the performance of a mobile phone battery. 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.
4, technological progress to reduce the cost of wireless charging, mobile phone support Qi wireless charging has become a common phenomenon, just like the dual camera from the flagship machine to expand to a thousand yuan machine. AirThe addition of Pods2 accelerates this process, indicating that more non-flagship and mid-range phones may come with wireless charging as standard.
5, through the built-in voice chip of the product, it can also directly say "open the bracket" to release the arm, which can provide users with certain convenience in certain circumstances, and is also a highlight of 360 wireless charging mobile phone bracket compared with similar products. I believe that you have a comprehensive understanding of the 5 products tested.
Download and install: Visit officialDownload the wireless software from the website or app store and follow the prompts to install it. Registration and login: Open the software, follow the instructions to register, and log in to the account. Scan and connect: Enter the software interface, open the wireless network scan, the software will automatically search the nearby wireless network, select the network to be connected, click Connect.
To use wireless software, first make sure that the phone is not connected to WiFi. Turn off your phone's WiFi function, then switch to a mobile data network using your phone's SIM card. In your phone's Settings, find the "Wireless and networking" option and go to the "WiFi" settingSelect the "cmcc" option, but do not save the Settings. Open the wireless client, switch the WiFi device status from "OFF" to "ON", and click "China Mobile WLAN".
Free CMCC connection with software First of all, with the help of a tool called Changwireless, you can achieve one-click access to the national CMCC and ChinaNet hot spots without binding to a mobile phone number operator. Here are the steps: Download and install the wireless app, turn on your phone's WLAN, and keep your mobile data on. Search for and select the CMCC network to start authentication. The system displays that the CMCC network is connected after authenticationWhat are the requirements? '> What are the requirements for wireless charging QI certification?
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 implementation, interoperability verification, product information revision and final review, which are included in the WPC product database.
2, power output and stability: in XIn the YZ axis translation test, the wireless charging capability of the device at different angles is verified. Energy transmission limit: Test the maximum power supply capacity of the equipment to ensure safety performance. Foreign body detection: Ensure that the equipment can still work normally in the presence of foreign bodies to prevent safety accidents. Compatibility testing: The transmitter is subject to interoperability testing with all QI-certified receivers to ensure seamless connectivity.
3, registration. Product availability: Submit samples for testing. Compliance and compatibility testing: Strict quality and functional testing of products to ensure compliance with standards. Final confirmation: After passing all tests,Confirm that the product is correct. Audit and certification: Finally, after the authoritative audit, issued Qi certification.
4, wireless charging Qi certification test includes Compliance test and Interoperability Test. The compliance Test was conducted by the Authorized Test Lab (ATL) with 5 samples.
5, after the Qi certification, it will be tested for safety, effectiveness and compatibility by the Wireless Charging Alliance. Qi certified deviceThe operating power must be 0-30 watts (Qi standards can reach 1 kilowatt, but not for mobile phones), pass temperature tests and comply with Qi FOD standards. They also need to be compatible with all other QI-certified devices (phones or chargers), just like all Micro-SD cards are compatible with all Micro-SD ports.
6. According to the requirements of WPC, all test samples need to be tested for compatibility with all previous certified samples. If the product tested is a wireless charging transmitter, then it is required and WPC all over QiCertified receivers do compatibility testing. Compatibility testing includes two aspects, first, when the transmitter and receiver are placed together, the two need to establish communication within 3 seconds.
