Problems solved by technology

Therefore, it is particularly important whether the power display on the battery bar is accurate. If the code written by the software development does not correspond to the number of grids displayed on the battery bar, it will easily cause the empty battery to be displayed quickly on the interface of the portable electronic device. The user causes the portable electronic device to consume too much power or the battery is not durable, etc., which will greatly affect the user's desire to purchase

Embodiment approach

[0025] During the specific test, the digital power supply first supplies power to the mobile phone through a fake battery and turns it on. The mobile phone displays the corresponding power (number of cells) in the battery column according to the level of the battery voltage. As a specific implementation of the power supply voltage in the mobile phone, the digital power supply The provided power supply voltage, that is, the first standard voltage of the digital power supply is 4.2V. Then turn on the phone and enter the standby interface state of the mobile phone, which is the first interface of the mobile phone. At this time, the battery bar of the mobile phone standby interface should be fully charged. Then gradually lower the first standard voltage value of 4.2V on the digital power supply, and the mobile phone can detect the voltage reduction. When the voltage decreases to a certain extent, the mobile phone will change the display level (number of grids) of the battery bar po...

Abstract

The invention provides a testing method for electric quantity display in a battery column in a portable electronic device. The method comprises the following steps of: S1: supplying power to the portable electronic device through an external power supply which is initially set to be first standard voltage; S2: opening the portable electronic device and enabling the portable electronic device to be in a standby interface state; S3: starting from the first standard voltage, gradually regulating the voltage of the external power supply, and obtaining the actual corresponding relation between the current voltage value and the corresponding current electric quantity display level in the battery column in the portable electronic device; and S4: judging whether the electric quantity display in the battery column in the portable electronic device is qualified or not according to the corresponding relation between the preset reference voltage value of each level and the standard electric quantity display level in the battery column. According to the testing method disclosed by the invention, whether the electric quantity of the battery is correctly displayed on the portable electronic device can be quickly judged, so that the risk during the project manufacturing process is reduced, the quality of software and hardware of the portable electronic device is ensured, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a test method for displaying the electric quantity of a battery bar in a portable electronic device. Background technique [0002] With the continuous development of electronic technology, portable electronic devices are getting closer to people's lives, and people are constantly pursuing more convenient enjoyments and more entertainment atmospheres. Ten years ago, portable electronic devices such as mobile phones appeared in front of people only as a communication device, but in today's network globalization, mobile phones have become personal "supercomputers", with various types of mobile phones, complicated program software, Constantly changing people's attitude and frequency of using mobile phones. Among them, the power of the battery is a test. Many smart phone users have to use it during the day and charge it at night, so the length of battery power has become an i...
