The OnePlus 3 set a new standard for reasonably priced smartphones when it was launched in June 2016. Offering an incredible combination of premium specifications and a $500 price, it carved out a whole new category; it was so good it had no close rivals.

The OnePlus 3T is a device that's stood on the shoulders of its predecessor to get ahead of the pack of top-tier smartphones on the market today. Instead of releasing an all-new smartphone, OnePlus has opted to chop their update schedule in two.

Pricing is still great; even $100 over OnePlus 3; Hardware is high quality; AAA production; Camera is amongst best in any smartphone; OnePlus supports ROM development; does not void warrantee for root; Display is top notch

No waterproofing; no dust-proofing; Phone's industrial design feels caught between safe and unique; OnePlus-made cases look cool; but offer little protection; Fingerprint scanner not quite as quick as Pixel XL or iPhone 6s/7

The OnePlus 3T is the flagship killer. The OnePlus 3's crown is being taken by the 3T. What was best about the OnePlus 3 is now made even better by the 3T: an upgraded Snapdragon 821 processor, a larger battery, an improved front camera and various software adjustments.

Good camera; Fluid; customizable interface; Quick "Dash Charge" system; High performance

No design update since the OnePlus 3; No microSD slot; Only Full-HD (1920x1080) Screen Resolution; No Android Nougat yet

The OnePlus 3T is hands down the best high-performance Android phone you can buy on a budget.

Blazing speed from Snapdragon 821 chip; Impressive cameras; Beautiful metal body; Smooth Android experience with regular updates; Very fast charging battery

Not water-resistant; Some software issues need fixing

OnePlus has released a matte-black version of the excellent 3T. Like the iPhone 7 before it, dark black is probably the perfect colour for a phone and the new 3T looks fab. It's only available in limited amounts, and in 128GB varieties, but it's still an excellent value phone.

Great build quality; Excellent performance; Good camera; Improved battery life

Not quite as fantastic value as OnePlus 3; Have to use proprietary Dash charger otherwise charging is slow

Has the smartphone brand let down its fans by keeping its new device almost exactly the same?

Still a great smartphone; with an improved camera and great battery life

Too similar to the OnePlus 3 to justify the increased price tag

The OnePlus 3T is still one of our favourite phones and it is now on sale in a stunning new Midnight Black edition.

It's been just six months from the launch of what was and still is a very popular smartphone in the Android smartphone market, the OnePlus 3 , and we already have its upgraded replacement called the OnePlus 3T .

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

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
