What performance tests are needed for mobile phone batteries to ensure quality?

With the prevalence of electronic products in daily life, batteries have become a common electrical device, providing stable voltage and current to power products steadily. Therefore, battery testing is a critical step in the design and production process of batteries to control the quality and performance and test if the batteries meet the standards, thereby optimizing the design to ensure the stable operation of electronic products. So, what indicators generally need to be tested for mobile phone battery tests?

Battery Capacity Testing

Battery capacity testing measures the battery's energy storage capacity, thereby assessing the battery's lifespan. This is generally done through discharge tests to determine the battery's capacity.

Voltage Testing

Testing the stability of the battery voltage, to determine if it is within the specified range, ensuring the battery provides stable power to the product.

Internal Resistance Testing

Internal resistance testing reflects the internal condition and conductivity performance of the battery. A higher internal resistance indicates poorer battery performance.

Charge and Discharge Testing

This tests the efficiency and stability of the battery during the charging and discharging processes.

Charging Speed Testing

Testing the speed and efficiency of battery charging to evaluate product performance. For example, with the advancement of science and technology, the design of mobile phone chargers is also gradually optimized, and the charging speed is progressively increasing.

Cycle Life Testing

An important indicator to measure battery life, involving multiple charge and discharge cycle tests to observe capacity degradation and assess battery life.

Safety Performance Testing

Safety performance testing includes tests under extreme conditions such as short circuit, overcharge, over-discharge, high-current charging, and drop tests to ensure battery safety.

Environmental Adaptability Testing

Testing the battery in different temperature environments to check its performance under various environmental temperatures.
