Extremely high CPU when running on Device

Hey all.

Has anyone come across a situation where their Ionic app works perfectly in the browser, but when on testing on a device it freezes with it is consuming a massive amount of CPU?

This is recent screenshot of the app being built onto an iPhone 5.

The web thread consuming all the CPU for the first minute or so, and then it drops off and the app works perfectly again.

Any help would be appreciated.

This only occurs when running on actual device, not the simulator.

Hi, any news about your problem ? I got the same on my Ionic app on iPhones.

I have seen this happening on iOS 7.1.2 device. Any one has work around?

Happens all the time for me…randomly… no idea yet whats causing or how to fix/prevent.
