That's the point I was trying to make. The closest you could do is approximate the results by running the phone for a week one way, and carefully documenting the amount of time it was used each day and how long the battery took to reach a certain level each day, then averaging out those two figures over the entire week. Then repeat the process for another week with the other charging method. It's not precise, but hopefully the week's worth of results would put it through a wide enough variety of usage styles that it'll cancel out any unusual usage patterns that would invalidate the test.
It's the best you can do without precise tools like the ones you mentioned, not to mention a control group of multiple phones with multiple users and blinding the user from what charging method was used to prevent subconscious observations or usage patterns that could skew the results.
