WiFi

On the OnePlus One, it's quite surprising to see the retention of 802.11ac WiFi as such features are often the first to be cut to reduce the price of a product. In the case of the OnePlus One, we see Qualcomm Atheros' WCN3680 solution, which is a single spatial stream for a maximum physical link rate of 433 Mbps. While the physical link rate is one thing, practical bandwidth and performance is another. In order to test this, we use iperf on Android with Asus' RT-AC68U for maximum perfomance in this area.

WiFi Performance - UDP

In this test, I saw that the OnePlus One noticeably out-performed the rest of the single stream competition, but I suspect that there are some irregularities here as iperf would report bandwidth above 433 Mbps in certain cases. Subjectively, there are no real issues with WiFi performance and one should have little issue with this on the OnePlus One.

GNSS

As one might have guessed, the OnePlus One leverages the on-die modem for GNSS. This means that one can expect IZat (GPSOne) gen 8B. In general, I haven't found any issues with GPS on this device. With a cold lock (airplane mode on, no assistance data) I found that it took around 50 seconds to first acquire position, then around another 30 seconds to get high accuracy.

Misc

The haptic feedback on the OnePlus One is noticeably different from every other device I've used, with much more noise than vibration. The same TI BQ27541 fuel gauge is shared with the Oppo Find 7A, as is the TI BQ24196 charger chip. Reception, at least for T-Mobile US' band 4/AWS LTE is noticeably worse than most devices that I've tried. The dual speakers are loud and the quality is relatively good, but no better than what one might find on the iPhone 6.

    How bout a Samsung Alpha review? The >5" space doesn't suit me.

    So, in summary, you liked the phone but cyanogen had too many options? I'm pretty sure this phone is targeting those who enjoy the additional privacy and options provided by Cyanogen. Anandtech as a whole seems to conveniently ignore the privacy issue as a whole (very disappointing, btw) but to do that for this review is to completely ignore one of the main reasons why this phone has become so popular. Yes, one can put cyanogenmod on most any android device, but not everyone has the will or the know-how to do so.

    "..the first to kill the concept of a 650 USD"... but what about Nexus??

    They should have used Windows Phone for the OS, then it would have been 100% polished and virus free...

    So, why not review the Sony Z3 as well?

    Here si an invite which have 12 hours left: GLVT-FMIA-VRIY-JQHG.

    I am a happy customer of this product since 3 weeks. I planned to buy the Nexus 6 but changed my mind because the hefty price tag.

    I am an AnandTech reader since the 440BX days.

    I don't agree reviewer point about software. For example, I am so happy to be able to block by default all the intrusive apps request to personal stuff as localization, address book, journal logs, photos and so on. CyanogenMod is a must.

    It is sad that OnePlus plan to use their colorOS for their next flagship killer.

    Finally, this is true that the device height is a bit too big for me but since it is a bit less than iPhone 6 plus, this is acceptable. Anyways, I bet everyone will follow the band wagon and change their small iPhone 4/5 for phablet within the next two years.

    I should have posted this earlier, but I was able to purchase the 1+1shortly after it was released. After having used it for a while, I can confidently say this is one of the best phones I have ever used. It feels like a very premium device and the grey, fine-sandpaper textured back does wonders for grip. At first I felt it was a little too big (I feel 4.7 - 5.0 is the sweet spot) but I quickly got used to it. The screen quality is great as well as the sound (obviously not as good as HTC One). As a fairly heavy user, the battery is up to task. It last all day and I come home with a solid amount of battery left (around 40%). To get an idea of my typical day: GPS high accuracy is always on and I use the phone for emails, texts, google maps/yelp, Uber/Lyft, watching movies/shows and reading kindle books during commute to and from work.

    In terms of the software, Cyanogen Mod is highly customizable and response time for launching apps and switching screens is fast. I have recently (over the past 2 weeks) had a couple of glitches but these were minimal such as the lock screen being unresponsive until I pressed the power button down again to wake it up.

    I live in NYC and have used the phone on both T-Mo and AT&T. It was as simple as popping in a SIM card and the phone worked right away. I was impressed as I expected to have to switch up a lot of settings. Call quality is good, especially on AT&T. I wish there was a version of this phone that supported VZ bands!

    If you have the opportunity to purchase this phone, I say pull the trigger! Paying $350 for 64gb is a great deal considering this is a premium device from a new company with great support. The forums are very active so you can get help quite quickly if you need it. As a guy who switches his phone around once per year (awesome corporate phone policy!), the 1+1 was awesome enough to keep me from switching to an iPhone 6+ as well as the Nexus 6 so it is a great device. I highly recommend it!
