Thanos Didn't Even Fight At Full Power

Did Thanos held back his true power during the Infinity War fight?

We are looking at the evidence from the battle against the Avengers on Titan to see why he wasn't using his full strength. It is clear that despite their best efforts, the team stood little chance against a version of the Mad Titan who wasn't even trying.

Let me know in the comments if you agree with this MCU power levels theory or if you think the heroes were just outmatched.
