Hi I'm currently experimenting on a oneplus 2 (sd810, msm8994) to see how low I can undervolt. I just have a question is very low voltage harmful to the device?

I dont think so, it wouldn't be harmful to a full size desktop processor anyway. You could introduce instability of course if the voltage is inadequate for the processor, but I doubt it would permanently damage anything. However I have never under volted a cpu that was not an amd or intel x86 processor so I cant say or sure how some qualcomm cpu or whatever that phone uses will react to being under vollted, I also dont know what value is equivalent to cpu vcore on a mobile processor.
