In consumer or medical devices that depend on precise fluid delivery (like…
In the manufacturing of high-performance electronic devices, two issues often come under scrutiny—Runtime Drop and Thermal Failure. While these problems may appear independent at first glance, deeper technical analysis reveals that they are, in fact, closely interrelated. Understanding the relationship between runtime decline and thermal stress is critical for OEM and ODM partners who demand reliability, safety, and durability in their products. What is Runtime Drop? Runtime Drop refers to the unexpected reduction in operational time of battery-powered devices such as electric toothbrushes, water flossers, or portable appliances. When the runtime does not meet the expected or rated duration, it causes end-user dissatisfaction and increases warranty returns. This can be caused by various factors—such as battery degradation, increased internal resistance, or external environmental conditions. However, an often-overlooked contributor to runtime drop is thermal stress. Excessive heat generation within the device during operation can accelerate battery aging, directly reducing usable capacity and causing runtime to shorten over time. What is Thermal Failure? Thermal Failure happens when a device or component fails to manage or dissipate heat effectively, resulting in overheating. This condition not only risks immediate functionality loss but may also lead to permanent damage of internal parts—such as PCB warping,…
