Bad frame rates at the lowest settings

I recently got Minecraft on my iPad! iPads are known for being on the high end side of tablets! So, with Minecraft, you would expect it to run like butter! Wouldn’t you? Well, it can’t seem to run MCPE well on the lowest settings on a flat world! Whenever I fly around, or even spawn and kill a mob, or simply play the game, my frame rate drops to 30 for some reason! Why does this happen? This issue needs to be fixed immediately! I don’t know why it isn’t running the way it should!
