Had my Plus since Friday, no bends yet, what do I win?
It's really not for everyone but I love it. Battery life is definitely a step forward, been using it with my typical, fairly heavy, daily usage + a little extra 'cos it's new and shiny. Using dawn till dusk without extra charging, it's never dipped below 10%. Given the battery will lose 10% or so with age, and I'll use it maybe 5% less once the new shiny appeal as worn off, overall I think I can realistically use it a day without a midday charge. Note, I don't do any gaming on my phone for battery reasons, throw games on there and I'd definitely need a quick charge.
Screen is notably brighter than my previous phone, 5S, can see it pretty well in bright sunlight. Pretty surprised on that score.
Also, seem to get a better signal in places where I'd normally get just about one bubble. My rMini always got a better signal on the same carrier (EE) in the same place as my 5S. The 6 Plus seems to get the same as my rMini, which is bonus as I travel all over the place on the train.
Also, at LAST, I can type in portrait comfortably.
The only downer, personally, is my need for a case.
Always used phones nekkid, but combo of larger, thinner, rounded edges make it impossibly slippy. Plumped for the silly priced leather Apple case, Black, it's about 1,000 times grippier with it on. Plus, I can actually pick it up off a table in a case, it's surprisingly tricky without.
Makes it look like a typical huge Samsung phone actually, which is fine by me. 'Dat Space Grey slab of alu is pretty conspicuous.
