My iphone 6 Plus has great battery life. Just as good as my Note 4 and best at idle/standby time.It's a good start but I'd take these results with a grain of salt considering what many have experienced in real life usage. Haven't quite a few Note 4 users on these forums claimed their battery performance diminished considerably when the Note 4 was updated to Lollipop--the same version the Note 5 ships with? And jamerz, please correct me if I'm wrong but didn't you even say that the iPhone 6+ was at least as good as, if not a little better than your Note 4 concerning battery life? I only mention the latter because according to these tests, the Note 4 should be 2 hours better than the 6+. Same goes for the Nexus--I've yet to see anyone claim the Nexus 6 has better battery life than the iPhone 6+ yet this charts claims otherwise.
Again, not here to tout the iPhone 6+ but rather emphasis a bit of caution regarding these early benchmarks.
I do take these tests as a good indicator of what to expect. Nothing more. There are some that say they get 8 hrs SOT on a Note 4 but I have never gotten that. there are some that say they get some kind of great battery life on there iphone 6 plus...but I have never gotten that.
The same with benchmarks. They are a good indicator of what to expect in performance.
