It has usually been Apple who can get away with incremental changes to their flagships. OnePlus have learn't from the master of the game. And so six months after the OnePlus 3 made waves in the mid-range market, the disruptive manufacturer is back.

Top line processor; fantastic looks; Good battery; latest Android; Under-￡400

Incremental changes since OnePlus 3

What do you do when you have an already-great smartphone and access to parts that can improve it? If you're a traditional smartphone maker, you'll more than likely wait around 12 months before putting those upgraded parts into a slightly newer chassis.

Stunningly fast performance; longer lasting battery and Dash Charge super-fast recharge; great build quality; AMOLED display is bright and colourful

Still just a Full HD display; camera could be better; no microSD expansion; no Android 7.0 Nougat base (yet; anyway

When flagship-quality specs are this cheap, why would you bother buying anything else?

Outstanding value; Impressive performance; Attractive design

Not as good value as the OnePlus 3; No MicroSD card slot

It's not quite as bargain-tastic any more, but the 3T still packs performance where it counts

Still great value; A little bit more power; Fab design

Selfie camera not much of an improvement; Battery life doesn't seem to have increased; Significantly pricier than the OG OnePlus 3

OnePlus 3T is a fabulous phone with premium build quality, awesome screen and a great camera. It's a strong contender to Samsung Galaxy C9 Pro and yes if you love Android then you can consider this over iPhone 6S.

Premium design; solid build; great screen; fast charging; battery backup; camera; ample storage space

No microSD support

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

The OnePlus 3T is an excellent smartphone. The fit and finish is right up there with the best, the metal design is refined and even with a 5.5in screen, it's a manageable smartphone to use on a daily basis.

all-metal; great fingerprint sensor; good screen; fast charging; good cameras; excellent notification slider; dual-Sim with dual standby; cheaper than rivals

not quite as cheap as it once was; no removable battery; no expandable storage; slow charging from non-Dash charge power adapters; screen low res for VR; not yet running Nougat

Well that went quickly-the OnePlus 3 was a great phone, and when you don't change much, there isn't much to talk about. We doubt anyone would notice the camera and performance changes between the 3 and the 3T, so at the end of the day, you're really paying $40 for more battery life.

$439 for a 64GB phone is a fantastic price; The aluminum unibody is still great; Speedy SoC (a Snapdragon 821) and surprisingly speedy storage; just like its predecessor; It still has all the right extras: a fast; accurate fingerprint reader; USB Type-C; and NFC; Customizable; lightweight Android...

No MicroSD slot; Slow monthly and major Android updates; If you're going to upgrade a camera; upgrade the rear one

Several weeks after the OnePlus 3 came out, Ian Hardy, MobileSyrup ‘s publisher, asked me whether the website should run a "three months later" feature on the device. "Bossman," I said, "shouldn't we wait until the phone is at least six months old?

Superb performance & improved battery life; Near stock Android with smart additions; Handsome new Graphite colour

$100 more expensive; OnePlus 3 is still a great smartphone; Not water or dust proof like other flagships

OnePlus, the mavericks of the smartphone world, bucked industry trends once again by releasing an improved version of their super-popular OnePlus 3 just five months later in the form of the OnePlus 3T .
