HTML5 Canvas laggy on Chrome Android

Hello everyone, 

It's been a little over a week since I've been trying to solve an issue that keeps me awake at night.

It's about a project I'm working on that runs very slowly only on Chrome for Android. After much research, I found that the problem occurs when handling several large images (around 3500 pixels each).
I've confirm this by compressing big spritesheets images to 100kb each and still laggy if the images are biger in pixel size.  

The issue is that if I don't use spritesheets, the loading time increases considerably, taking almost a minute to load, compared to 5 seconds of loading time when using two giant spritesheets. However, on Android, the performance drops significantly. On the other hand, if I load the 72 separate images, the loading time increases to a minute, but the performance is excellent.

Could you share some experiences and/or suggestions on other methods to approach my problem? Or options to investigate?

Thank you for reading this,

Great performance but about 60 seconds to load:
