No. Just.. no.
First of all, it's a well known fact that their audio quality tests are a farce, as was confirmed by the legend Supercurio himself.
Secondly, have a look at this link:

There are so many things wrong with those results that it isn't even funny anymore. Firstly, do you honestly think that it's possible for the S6 and S6 Edge to get the EXACT SAME battery time for calls, browsing and video, right down to the exact same minute? No. It's an absolute and blatant lie which is severely misguiding everyone else who believe them based on their 'reputation'. I mean, even if there were two S6's, the god damn physics of the situation for them to have the EXACT same battery time for a given task is IMPOSSIBLE. So much for their credibility, then. Honestly, I cannot trust a website with such obvious lies.
Secondly, just have a look at this battery life:
I mean, wow. You'd think that the battery on the S6 is some sort of voodoo magic. Is this really the battery life everyone's been getting? The 72 hour 'endurance rating' ****e they've come up means that phone will last 3 DAYS with an hour of calls, browsing and video each day. Meaning, ladies and gentlemen, the S6 will have 3 days of standby time with 6 hours screen on time, thus solving once and for all the battery problems we must face with fast QHD phones, right? WRONG. At best, at its absolute very best, the S6 has very average battery to bad, and this is a well known fact. Ask anyone who has the GS6 and tell me if what GSMarena reported checks out. Hell, I had the S6 but returned it because of the poor battery - which, for my usage, was worse than the G3 i've had in the past.
It honestly wasn't all bad once upon a time. A majority of the phones I've had used to get battery similar to what was reported by GSMarena. But ever since the S4 and S5, their lies got frequent and nothing has checked out, for me.
