If you are running your app in development mode it takes some time to fire the platform.ready() event since it has assertions and various necessary framework checks turned on.

Try running the app in production mode to speed up and optimize the start of your application

If you're in an ionic 2 app, you can enable this by doing the following,

open src/app/main.ts

Import enableProdMode from Angular 2 core

import {enableProdMode} from '@angular/core';

import { AppModule } from './app.module';

Then call the enableProdMode() function before bootstraping your module

enableProdMode();

platformBrowserDynamic().bootstrapModule(AppModule);

and now while running the app through cli try adding a flag like "--prod"

ionic run android --prod

In ionic 3.x, you don't have to enable anything in the code. you can simply run it using the cli command,

ionic cordova run android --prod

check this documentation from angular.io

Hope that helps
