Is there a difference between Yoda challenge on iPad and Iphone?

I ask this because I am getting destroyed on the iPhone when trying the the 5th round like it was before Devs tweeked it.
Literally Yoda gets 2 attacks for every time 1 of mine attacks.
I cannot even drop him down 2 notches on hitpoints.
But on iPad once adjusted I could complete the challenges.

Do you use same chars with similiar gear/lvl ?

Close, but not exactly! But still enough to kick butt.
