You mean the widely known unreliable GSMarena testing who doesnt even disclose their testing unlike other tech websites, And how most other battery tests from other tech websites dont really line up with GSMarenas results?
Yeah, its too bad even though you handpicked results you were still hard pressed to find anything good
20nm Apple A8>>> 28nm S805, this is obvious, the general consensus agrees and shows the 6 Plus on average has better battery life, this is obvious by just looking at the spec sheet, the 20nm Apple A8 is noticeably more power efficient then the Note 4's S805, and also the 6 Plus gets almost double the gaming battery life of the Note 4, while having better GPU performance and longer sustained performance from the Plus over the Note 4,(note 4 throttles back way early, and performance goes down)
6 Plus has better browsing and wifi battery life times, offers almost 2x longer battery life when gaming also and has the Note 4 also beat on standby time while the only advantage the Note 4 has is a little longer lasting battery life in video playback only...so how exacty again does the Note 4 have better battery life in day to day usage?
Both still have stellar battery life though and are great
