Loading app taking too long

I’ve build an small/simple app with ionic 2.
But when I try open it on my phone it takes more than 10 seconds to load.
I don’t know if this is an ionic2 issue for or has something to do with my code.

I tried using enableProdMode(); but I get the same result: 10 second for loading.

my main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
import {enableProdMode} from '@angular/core';


My technologies:
Cordova CLI: 6.4.0
Ionic Framework Version: 2.3.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
Ionic App Scripts Version: 1.1.4

Is there a way to lower the time for loading the app?

Thanks in advance.

Have you tried using --prod when building? This helped me. Example: ionic build android --prod


Thanks for the suggestion. Worked for me as well.
