I think dash charging is great, but a comparison of 50% S7 to 67% OP3 does not compare effective battery life. So if (hypothetically) the S7 can get 8 hours from 50% and the OP3 only gets 6 hours from 67%, then the S7 50% charge is more effective. Not saying that is the case, just that battery % is only comparable on the same device -- and even then you have factors such as battery age.
