Average Test Runtime
598 ms
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: 385 ms to 986.3 ms
Standard deviation range : 323 ms to 873.1 ms
Coefficient of variation : 46 %
Average FPS
42 FPS
Frame Per Second. Your app should display 60 Frames Per Second to give an impression of fluidity. This number should be close to 60, otherwise it will seem laggy.

Min Max Range: 41 FPS to 43.1 FPS
Standard deviation range : 41 FPS to 42.8 FPS
Coefficient of variation : 1.8 %
Average CPU usage

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 4 cores, so the max value would be 400%.
Min Max Range: 102 % to 103.5 %
Standard deviation range : 103 % to 103.5 %
Coefficient of variation : 0.5 %
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 60 FPS.
Min Max Range: 9000 ms to 9500 ms

Average RAM usage
127.7 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)
