Well, you are running an almost 3 year old Android device. I have an HTC one test device and it does run pretty bad, but so does everything else on it (edit).
Really, you can't remotely compare a desktop to that phone (quoting the 60fps n Chrome Preview). Do you have another device or an APK that I can test on. I do a lot of testing on a Galaxy S3 or Nexus 4 at work (baseline for newer phones in the last 2 years)
