The OnePlus 3T is a worthy successor to the OnePlus 3 . However, the task has not been too challenging for the manufacturer because the previous model was already one of the best high-end Android smartphones. The changes for the OnePlus 3T are also pretty small, so this is still the case here.

high-quality chassis; high-end performance without throttling; good camera; fast storage; fast WLAN; dual-SIM; notification lever; USB Type-C; up to 128 GB internal storage; decent voice quality with noise suppression; good display; Quick-Charge; long battery runtimes

only LTE Cat; 6, different frequencies depending on the region, no storage expansion, no FM radio, webcam not as sharp as before, no Infrared, speakers with some static, no headphones in the box

With a better processor, battery, and front camera, the OnePlus 3T is a tune-up of an already great phone.

Great specs for the money; Larger battery ensures a full-day's charge; Adds 128GB option

Costs $40 more than the OnePlus 3; Higher-resolution front camera doesn't add much to selfies; Still no Verizon or Sprint support

If you have a OnePlus 3, the OnePlus 3T is not a big upgrade. If your budget is around 30-35k, the OnePlus 3T is indeed the best smartphone to buy. It is the most value for money smartphone in the market today.

Class leading performance; Premium build quality and design; Super fast to charge; Good display

One day battery life only

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

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.

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

But now you can't buy the OnePlus 3. Instead, OnePlus has decided to replace it with an even better version: the OnePlus 3T. The 3T shares many of the same qualities as the 3, including the same materials and design; same size and resolution display; same 6GB of RAM; and same rear camera.

Great build quality; Fast processor and performance; Long battery life

Doesn't work on Verizon or Sprint; No certified water resistance; Quick charging limited to included cable and power brick

The previous OnePlus 3 was already the best phone for the money, and while the 3T's $439 starting price has upped the ante a bit, improved performance and an extra 2 hours of battery life are worth the extra $40.

Excellent battery life; Great performance; Superfast Dash charging

Limited to GSM carriers; Display could be brighter

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

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
