[OnePlus 3 Questions & Answers] StephenP85:
I would definitely be interested in as many real assessments as possible from 6P owners who are giving the OnePlus 3 an honest trial period. My wife is ready to ditch the iPhone 6 and switch to Android. Never thought I'd see the day. In an attempt to avoid getting another $600+ phone, and because I'm leaning more toward a mostly stock android experience for her, we've been considering the OnePlus 3 and the Nexus 6P. She was previously turned off by the 6P because of the size, but I convinced her it's not as bad as my Nexus 6 and is really not THAT much larger than the OnePlus 3. She'll ultimately leave it up to me to make the final decision. I'd prefer her introduction to Android be as problem-free as possible.

This is a long post about the concerns of selecting either phone for my wife, so feel free to ignore unless you'd like to offer some reasonably impartial insight as an owner of either phone.

So far, my concerns about the OnePlus 3 are:

The speaker. Not that it's going to be particularly crappy, but the iPhone 6's speaker is a real PoS compared to the Nexus 6's dual speakers, and it's something my wife has noticed in particular, but doesn't necessarily have to have it. It's probably a bigger problem for me when my ears are assaulted with piercing treble when she blasts a song or video.

Battery. Seems the consensus is that it's OK, should get you through the day perhaps, maybe, depending on usage. The iPhone's battery has not been adequate for her to get through the day, but it's tough to gauge whether the OnePlus 3 would be better or worse in that regard. I've read up on the aggressive (but changeable) memory management profile that seems to have been implemented to make up for the reduction in battery capacity. The wife is envious of my N6's battery life. The workaround, I suppose, would be to buy the dash charger for the car.

Just the general comments I'm seeing about random bugs on OxygenOS, with which I have no experience. The main concern is ensuring that the experience is buttery smooth, completely responsive, with extremely minimal crashing. Multitasking and speed of launching apps is far less of a priority.

I could be wrong, but it seems that timely updates will be an issue? (this is a question out of ignorance, but it would be nice for me to be able to update her phone as updates/fixes come out, maybe even get her on N.)

6P concerns:

Whether or not throttling is an actual issue and if so, whether or not it will be an issue for her usage. Tough to get a real assessment on that, because anecdotes are skewed; people's egos are so fragile about their phones that they'll employ any amount of mental gymnastics to minimize their perception of their own phone's flaws. The main concern would be thermal throttling's effect on extended usage in normal browsing and basic games, whether scrolling gets laggy and/or the phone feels hot etc.

Brightness. Can't get a read on that anecdotally either. The brightness of my Nexus 6 is the worst thing about it. Out on the lake on a clear day, it's practically unusable. Consensus so far is that the OnePlus 3 seems to be just fine (or even great) in that department.

Lack of OIS. Seriously, disappointing that it was removed. I don't take nearly as much video as my wife does but she still notices how much nicer my videos look on the N6.

And in general, considering the fact that it will cost a bit more than the OP3 for the 64gb version and that the size may still be unwieldy for her at first, determining whether the phone is worth those two concessions.
