Battery runtime can be affected by multiple factors and does not necessarily indicate a product malfunction. The following conditions may cause the battery to appear less durable during use.
1. Ambient Temperature Effects
Lithium batteries are sensitive to temperature changes. In low-temperature environments, internal chemical reactions slow down, reducing available capacity. In high-temperature conditions, battery aging accelerates, which may lead to long-term capacity degradation. Seasonal changes and ambient temperature differences can noticeably impact battery performance.
2. Natural Battery Degradation
Batteries are consumable components. As charge and discharge cycles accumulate, the maximum available capacity gradually decreases. This is a normal characteristic of lithium batteries and occurs even with relatively light usage over time.
3. Usage Scenarios and Power Consumption
High-power usage scenarios—such as extended continuous operation, enabling multiple features, or connecting external devices—significantly increase power consumption and result in shorter runtime compared to light or intermittent use.
4. Charging and Usage Habits
Frequently draining the battery to zero, storing the device at full charge for extended periods, or using non-compliant charging equipment can accelerate battery aging and reduce overall battery lifespan.
Note
All of the above scenarios are common in electronic products. If battery performance changes significantly, it is recommended to evaluate the device based on actual usage conditions and environment.
