When Apple SVP Phil Schiller pointed us to a story earlier this week that Samsung was artificially inflating benchmark scores for its new Galaxy Note 3, many were quick to point out it wasn’t the first time Samsung had been caught engaged in such a practice. The same issue was discovered by AnandTech for the Galaxy S4 back in July, and today the site has an extensive report showing that almost every Android smartphone manufacturer is shipping devices that do the same.

As pictured in the chart above, that includes the HTC One, HTC One mini, LG G2, Galaxy Tab 10.1, and many others. In fact, the only companies that appear to not be using the method is Apple and Motorola, as well as Google with its Nexus 4 and Nexus 7 devices:

As noted in the report, the gains that OEMs are experiencing from the inflated scores are probably not worth the press they’ve been receiving. AnandTech points out that most of the inflated scores provide under a 10% increase in GPU and CPU performance benchmarks:
