Summary:

Whether the end user is satisfied with the design of his portable device depends to a large extent on the performance of the battery. The key indicator of the battery is of course the battery life. On the surface, this is only a simple value, but it involves many factors, including: system load (power supply time of full load current, power supply time in standby mode), Power efficiency, system power management, battery type and charging method. The interaction between these features can also affect the end user's feelings. In general, when users start to notice the battery, things become more difficult! Good product design does not require frequent battery replacement (such as TV remote control), nor does it need to charge the battery frequently (electric toothbrush). It should “disappear” the battery from the user's eyes to avoid the user's attention to the function of the device. Pay attention to the battery.

The mutual constraints between the battery and the system are often overlooked in the design, and it is critical to ensure that the battery capacity matches the requirements of the system. Commonly used battery types are: alkaline batteries, nickel metal hydride batteries and lithium ion batteries. They are not interchangeable and have an optimal solution for most products.
