Time taken to run the test. Can be helpful to measure Time To Interactive of your app, if the test is checking app start for instance.
Min Max Range: 397 ms to 1048.2 ms
Standard deviation range : 329 ms to 925.1 ms
Coefficient of variation : 47.5 %
Average FPS
41.9 FPS
Frame Per Second. Your app should display 90 Frames Per Second to give an impression of fluidity. This number should be close to 90, otherwise it will seem laggy. See this video for more details
Min Max Range: 41 FPS to 43.1 FPS
Standard deviation range : 41 FPS to 42.8 FPS
Coefficient of variation : 2.2 %
Average CPU usage
102.7 %
An app might run at high frame rates, such as 60 FPS or higher, but might be using too much processing power, so it's important to check CPU usage. Depending on the device, this value can go up to 100% x number of cores. For instance, a Samsung A10s has 8 cores, so the max value would be 800%.
Min Max Range: 101 % to 103.6 %
Standard deviation range : 102 % to 103.6 %
Coefficient of variation : 0.9 %
High CPU Usage
9.2 s
Impacted threads:
- UI Thread for 9.2s
High CPU usage by a single process can cause app unresponsiveness, even with low overall CPU usage. For instance, an overworked JS thread in a React Native app may lead to unresponsiveness despite maintaining 90 FPS.
Min Max Range: 8500 ms to 9500 ms
Standard deviation range : 8695 ms to 9638.1 ms
Coefficient of variation : 5.1 %
- UI Thread -
Min Max Range: 8500 ms to 9500 ms
Standard deviation range : 8695 ms to 9638.1 ms
Coefficient of variation : 5.1 %
Average RAM usage
130.7 MB
If an app consumes a large amount of RAM (random-access memory), it can impact the overall performance of the device and drain the battery more quickly. It’s worth noting that results might be higher than expected since we measure RSS and not PSS (See here for more details)
