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 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

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

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 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.

-Thin and light metal design; Beautiful 1080p panel DASH charging works as advertised Great all day battery life Performance is smooth and responsive Great all around rear camera Improved front facing camera Dual SIM Fast fingerprint sensor OxygenOS is more refined

No expandable storage Single bottom firing speaker

One plus did a great job with this phone and this the only Android phone can keep up with iPhone when it comes to performance. Know that S8 it's out, but this phone still fast I think it's even better than S8 when it comes to multitasking depsit older chipset SD 821 vs SD 835, but 6 GB, no micro SD...

Excellent phone

When you want to connect your phone to public wifi it doesn't work unlike other phones

china best company i have use this mobile since 4 months sometimes it hangs and very fast battery draining so i can't say this mobile is better or failure

camera only daylight; ram; gaming experience; budget phone

battery; not handy; no service center in my town; speaker should be better

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

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

Even forgetting the price, the OnePlus 3T is a terrific flagship smartphone which can proudly hold its own against the likes of HTC , Samsung, LG and Apple. OnePlus has nailed that 'premium' feel with the new aluminium unibody, and the performance is right up there with the big dogs.

Design; Performance; Affordable flagship

Price creeping up; Not waterproof
