What to fix?

Test more often so that you don't break the CPU handling further in your next builds. CPU Score is in danger zone. Heavy battery consumption expected.

Build v1.8.23 did better in Memory . Spikes in Memory contributed to score drop by 13.33%

Build v1.8.23 did better in CPU . Spikes in CPU contributed to score drop by 10%

The app has a high performance risk for the phone manufacturer(s) Motorola, Lenovo, Samsung. Check coverage report for more details.

7 tests need immediate attention. View performance graph.

Utilization of CPU is close to the threshold.

Coverage: Android version coverage for reports will range between 5.1.1 to 7.1.2

Your average App Dalvik usage surged by 22.53%, Your memory score is 2.6

Follow simple UI hierarchy by reducing nested layouts to Relative layouts.

Caching: Use LruCache for data caching to optimize memory usage

Printing logs on callbacks would make debugging easy for tests run in our platform

Do not initialize objects that aren't necessary during launch times. Moving to singleton pattern helps

There is high probability of identifying risks running the apps with conditions

Upload APKs with and without 3rd Party SDKs to monitor and optimize the impact of app performance

Avoid wake-locks in background, using Batch and schedulers APIs such as GCM, Job schedulers could reduce wake-locks

Testability: Providing login / sign-up details could very well improve depth of bot clicks

Fix Oncreate() if the launch time is exceeding more than 3.2 secs. Try deflating views and layouts to optimize.

Optimize the app to render elements at 60 FPS for buttery smooth experience.

43.60 MB of App Dalvik utilized by activity View details

Below 10 MB approach would increase app installs in crowded markets such as India, China and Russia!

Fix & Optimize launch time using Flatbuffers for storage and rendering performance.

Well done, Network consumption has come down by 32.97 % compared to build v1.8.23
