What to fix?

5 Risk(s) are due to Data Sent/Received in Network exceeding the threshold.

Build v8.2 did better in Memory . Spikes in Memory contributed to score drop by 8.33%

Fixing CPU risks could drastically improve Chhi Score. There are 12 CPU risks.

Build v8.2 did better in CPU . Spikes in CPU contributed to score drop by 17.39%

12 Risk(s) are due to Threads in CPU exceeding the threshold.

Fixing Network risks could drastically improve Chhi Score. There are 5 Network risks.

App launch time went up by 59.09% initlizate network calls after few seconds of loading the resources. View details

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.

The app took 4.86 seconds to load on Android OS version 5.0.2. Usually anything more than 3.2 seconds results in user drops. View details

12 tests need immediate attention. View performance graph.

The app'sNetwork score has improved by8.33%!

11 Risk(s) are due to CPU Load in CPU exceeding the threshold.

Utilization of CPU is close to the threshold.

The app has a high performance risk for the phone manufacturer(s) Karbonn, Panasonic, LYF, Lenovo, YU, Micromax. Check coverage report for more details.

Network utilization on Panasonic P55 exceeded 1024 KB, you might want to consider bringing it down

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

Your average App Dalvik usage surged by 5.02%, Your memory score is 3.3

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

79.31 MB of App Dalvik utilized by activity org.jw.jwlibrary.mobile.activity.SiloContainer. View details

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

App makes 2274.85 KB of network requests. Moving this to a background thread will improve load speed. View details

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

Caching: Use LruCache for data caching to optimize memory usage

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

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

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.

Network utilization on Karbonn Titanium Machfive exceeded 1024 KB, you might want to consider bringing it down

Total Network data consumed was 2274.85KB in Karbonn Titanium Machfive , This indicates the app will take 10-15 seconds on 2G network and 8-9 seconds on 3G network to load! View details

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

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

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

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

Well done, Network consumption has come down by 86.22 % compared to build v8.2
