Mobile Device Run-down Testing Provides Realistic Assessment of Battery Performance
Technical Overviews
Conducting a run-down test on a mobile device with its battery yields unique and useful insights for optimizing battery run time.
It is important to test the mobile device and battery individually when determining and optimizing run-time. However, a battery is not an ideal voltage source; its characteristics interact with and inluence the host mobile devices’ power consumption. Because of this interdependency, a number of unique and useful insights are obtained only when you perform a run-down test on a device with its battery, together as a system. These insights include:
- Obtaining the most realistic performance and run-time to serve as a baseline to compare and correlate against results you get from other methods
- Assess the battery capacity and energy achieved in actual use against the battery manufacturer’s ratings to determine reasons for differences, if any
- Verify low-battery shutdown and full-battery charge termination (when batteries are rechargeable) thresholds on the mobile device to ascertain if it is making full use of the battery As you can see, performing a run-down test with the device and its battery is key and complementary to a suite of methodologies for optimizing battery run time.
