In that case you want to create a large-scale test setup rather than wonder about the behaviour of just six UI elements in the editor. Because all that matters is device performance and what you see in the editor in terms of batching could simply be a difference in behaviour due to the fact that yo…

It may be related to layouting. The basic principle of ensuring best performance with UGUI is to use more canvases. Put things that rarely or never change in one canvas, and things that change frequently and independent from the rest in their own canvas. For instance, rather than having a single H…

Thank you for the reply. However, it’s crucial that we understand exactly how it works, since we’re developing a large-scale game targeting low-spec hardware.
