Despite its limited product portfolio, OnePlus has managed to make a mark on the smartphone industry. The Chinese company launched with the OnePlus One ( Review ) in 2014 and earned positive reactions from users worldwide.

Just months after the OnePlus 3 came out, it's being replaced with an updated model that offers better performance. For starters, the OnePlus 3T is one of the fastest phones on the market, thanks to its zippy new Snapdragon 821 processor. And now, post-update, it's also one of the longest-lasting.

Extremely long battery life; Front camera performs well in low light; Excellent performance

No microSD card slot; Only compatible with GSM carriers like AT&T and T-Mobile; Dash charger doesn't work with all cables

The OnePlus 3T isn't a huge improvement over the already-solid OnePlus 3, but it's still a well-rounded unlocked phone with buttery smooth performance, long battery life, and highly customizable software.

Relatively affordable; Fast performance; Attractive metal unibody; Solid front and rear camera; 10+-hour battery life; Clean UI and highly customizable software; Larger storage model available; Dual SIM cards

Same screen resolution as the OnePlus 3, and less sharp than the competition; Lacks waterproofing and expandable storage

Should you get the OnePlus 3T instead of its similarly priced midrange smartphones? Yes. But when compared to flagships, we can't help but think long term. Software-wise, there's nothing to worry about as the dev community of OnePlus is very much alive and supportive but when it comes to hardware,...

Amazing build quality; AMOLED display; Outstanding performance; Capable cameras

Heats up quickly; Select LTE bands; No support for LTE 700MHz Band 28

Flagship killer might be too ambitious a label for the OnePlus 3T, but even as the priciest OnePlus to date, it remains value for money.There's still plenty to admire, and it's definitely one to consider if you're happy to negotiate its occasional shortcomings.Of course, we'd like to see...

Premium build; Fast performance; Decent battery life with fast charging; High-res music support; Clean user interface

Audio and video performances lack some subtlety; No microSD; No waterproofing; Low light camera performance could be better

The OnePlus 3T is well made and surprisingly powerful -- stacking up favorably compared to many, much more expensive flagship phones. The 5.5-inch AMOLED display is well liked and the phone features front and rear 16 MP cameras, which are regarded as solid.

Powerful performance; Clean user interface; Good cameras

No memory card slot; No support for CDMA networks (Verizon and Sprint; Best value direct from manufacturer

The OnePlus 3T is an excellent smartphone that ticks all the right boxes, but is very hard to find brand-new

Incredible value; A superfast handset for the price; High-quality screen

It's not as much of a bargain as the OnePlus 3; 16-megapixel front facing camera isn't great

It does everything really, really well, and while it may not truly excel in areas such as screen resolution and camera quality, the OnePlus 3T is still astonishingly good value for what is a serious flagship contender.

Great battery life; Super-slick performance; Still an affordable flagship

No microSD slot; Slightly more expensive; Incremental upgrades

The OnePlus 3T will be unfairly compared, for now at least, to the phone that came before it. So let's ignore it. On its own, the OnePlus 3T is everything a modern smartphone should be; slim, fast, and responsive, with above average battery life and cameras that produce stunning images.

The faster processor, an improved front-facing camera, and larger battery capacity also results in a bump in the price point, with the 64 GB model priced at $439, and the 128 GB iteration setting you back an additional $40.
