CPU usage on IOS/Android

Hello,

my name is Domenic and I'm developing an platformer game for Andoird and IOS.

I've got an huge perfomance issu on my IOS devices built with XDK, Phonegap...

When I Export the Project via HTML and upload it to my Website, it runs on my iPhone 6+ with 60 fps and 30% CPU usage, but if I export with Cordova and built an IPA it runs with 60 fps and 90%+ CPU usage. It heats up very fast...

I've made a Test game with just the tilemap and the Character. The same issue.

On my Samsung S3 the Test game runs with 52FPS and 25% CPU Usage (Crosswalk)

My Project settings:

• Sampling Point
• Physisc engine Box2D web (I dont use Physics)
• Preload Sounds Yes
• Clear background NO

My XDK settings:

Cordova CLI 5.1.1

Fullscreen

Landscape

IOS target 8

Here is an capx from my Test Project.

A response would be appreciated.

Cordova on iOS currently uses the UIWebView which lacks Javascript JIT support, so JS code runs ~3x slower which would explain the difference. You can enable it by finding a third party plugin to use WKWebView instead which does support JIT, or official support should be coming soon in cordova-ios 4.0.

Hello Ashley,

thanks for your reply.

I added the Plugin in XDK and now it finally works.

Thank you very much !
