Mobile devices are bad about Performance.
I have read that post about performance. It is not really helpful as my first app is just a flappy clone for testing how to compile an apk.
There are no ads so that is not effecting the performance.
there are only 5 objects in the game. the flappy, the pipes, the score and back ground.
when run as web app it flies on the same device so much so that I will need to set slower speed for pipes.
but when compiled as apk and run on the same device. it goes so slow that one tap is like 3 taps. it jumps up and up and up. so you can't even clear the first pipe.
Edit 1) I think I will try compiling without cordova and see what happens.
