iPhone bench marks are never faked. Only Android and especially Samsung scores are faked.
I know you're being sarcastic, but the funny part is you're actually right. Ooops. Bet you didn't mean for that to happen.
There are a LOT of faked low iPhone 6S scores. Like the ones I linked below:

http://browser.primatelabs.com/v4/cpu/183174
The first one is done better because it actually lists the correct processor. The second one is a poor fake as it shows Android as the OS and the wrong processor. Imagine that, some idiot benchmarking an old Android phone, changing the device identifier to "iPhone 6S" and uploading their result to try and trick people into thinking the iPhone 6S is really that slow. I can't describe how pathetic that is.
Now you're probably thinking "so a couple idiots did this - who cares". Well, no. You have to get to page 100 (and at 25 results per page that's 2,500 fakes) before you find results that are plausible. That's a lot of idiots on some crusade to try and lower the iPhone 6S score. I'm not sure what method they use (maybe they jailbreak an iPhone and tamper with how it runs to generate such a low score) but there's a lot of people doing this.
Apple is not the only one this happens to. The Samsung S6 and S7 (unfortunately, the S7 doesn't show up in a search for Geekbench 4 for some unknown reason) also get fake low score results. Probably from other Android users that hate Samsung. Although they are nowhere near as many as Apple. On the other end Samsung also gets ridiculously high scores posted. Even ones with Intel desktop processors that identify themselves as a Galaxy S6/S7. It's the same types of idiots trying to raise the score of their device by posting faked high scores.
It's also interesting to note there are zero (zero as in 0) faked iPhone high scores. The highest scoring iPhone 6S at Geekbench is only about 5% faster than the average score. So those are legitimate scores probably run on a device with absolutely nothing else running, all Apps closed and a cool phone that hasn't been doing anything to get warm.
The up side to this cheating? Geekbench obviously analyzes the results they get. And they don't post a device to their charts until some minimum number of tests are run (considering it takes awhile for a new device to show up this number must be large - as in several thousand). And they are obviously discarding results that are implausibly low or high. The end result is the score posted for a device is a fairly accurate average of numerous devices. Which makes me laugh at all the people uploading fake results, because it's not doing anything to affect the scores. I guess none of them never took Stats 101.
