Hello Nandish,

One option to consider is sleep or hibernation to avoid lengthy boot and application initialization times.  The NitroBoot product from Datalight provides some improvements over basic hibernate.  Here's a link to a demo: https://youtu.be/TRXtyRz3t5E

Hello Nandish SG,

The Qt5 image is big so I would also recommend looking into optimizing the Qt part of the image. There is some interesting documentation like the following blog entries from the official Qt blog.
