Six generations in, OnePlus has gone from internet cult favorite to mainstream player, and the OnePlus 6T is the phone where that shift is impossible to ignore.
This is still a fast, clean Android flagship, but the days of radical value and bold hardware decisions are gone. Now it’s about incremental upgrades, familiar compromises, and BBK group design templates.
Design: BBK DNA, Lifestyle Packaging, Familiar Compromises
The 6T looks like what it is: another BBK-era glass-and-metal slab that could pass for an Oppo R17 at a distance. Metal frame, glass sandwich, teardrop notch — very 2018, very on-trend, very not-unique. It’s 2mm taller, about 5% thicker, and a bit heavier than the OnePlus 6, mainly to make room for a larger display and a 3,700mAh battery.
Durability gets a partial upgrade. The front is now Gorilla Glass 6 instead of 5, but there’s no IP rating and no mention of tougher glass on the back. Long-time fans also lose the Silk White option at launch and are stuck with Mirror Black (glossy, smudge-prone) and Midnight Black (matte, more practical). Given the glass back, the lack of wireless charging is a pretty obvious omission.
OnePlus still leans hard on its “Never Settle” lifestyle branding. The retail box is genuinely premium-feeling, with rubberized coating, multiple trays, and the usual community-focused touches like quotes and a CEO letter. You get a pre-applied plastic screen protector and a thick clear case, plus a USB-A-to-C cable and 20W Fast Charge brick. But you don’t get headphones, and you now rely on a USB-C–to–3.5mm adapter for wired audio.
Display and Biometrics: Bigger AMOLED, Smaller Notch, In-Display Reader
OnePlus didn’t cheap out on the panel itself. The 6.41-inch 2340 x 1080 “Optic AMOLED” display comes in at 402ppi, with deep blacks and effectively infinite contrast. Peak brightness around the mid-400-nit range is solid for OLED, though claims about being among the brightest screens in the industry are more marketing than reality, and there’s no aggressive sunlight boost mode.
Color tuning is actually a highlight. Out of the box, the panel leans saturated and a bit blue, but you get multiple profiles: sRGB and DCI-P3 both test within color-accurate territory, with sRGB hitting an average deltaE of 2.4. Adaptive mode adjusts color temperature to ambient light, and you also get Night Mode (blue-light reduction), Reading Mode (monochrome), and an Ambient Display instead of a true always-on.
The teardrop notch is smaller and less intrusive than the OnePlus 6’s wide cut-out, but if you hate any notch at all, you’ll still need to mask it in settings and sacrifice a bit of usable space. There’s no notification LED; that died for the notch and top bezel shrink.
Under the screen sits OnePlus’ big new party trick: an optical in-display fingerprint reader. It’s not as fast as a classic capacitive sensor, but it’s one of the first implementations that’s genuinely usable. Accuracy is high, placement is reasonably forgiving, and speed is getting close to conventional readers, though still a touch slower. Setup takes longer because OxygenOS aggressively wants more finger coverage. If you’re not sold, face unlock remains extremely quick in good light.
Performance, Battery, and Audio: Snapdragon 845 Still Has Legs
Internally, the 6T is evolution, not revolution. It runs the same 10nm Snapdragon 845 as the OnePlus 6, with 4x Kryo 385 Gold at 2.8GHz and 4x Kryo 385 Silver at 1.7GHz. RAM tiers stay at 6GB and 8GB, but base storage is now 128GB UFS 2.1 with a 2-lane setup for slightly faster reads and writes. In practice, benchmarks show minimal gains over the 6; both are among the snappiest Android phones thanks to lean software, not magic silicon.
Gaming benefits from the 1080p-class resolution. The Adreno 630 GPU doesn’t have to push QHD+ pixels, so frame rates stay high even in heavier titles. The 6T does render a few extra rows of pixels versus the OnePlus 6 due to the taller 19.5:9 aspect ratio and slightly larger screen, but performance remains very strong and thermals stay comfortably under control.
Battery life is where the 6T quietly improves the formula. The 3,700mAh cell posts a 90-hour endurance rating in mixed use testing, with tangible gains in web browsing, video playback, and especially standby. It’s clear OnePlus did more than just bump capacity; software and modem optimization have been cleaned up compared to the OnePlus 6’s earlier network drain issues.
Charging is familiar territory. The 20W Fast Charge brick fills the phone from 0 to 55% in 30 minutes, and a full charge lands in just over an hour. It’s still the split-battery “divide and conquer” approach OnePlus has used for a while. No 50W Oppo-style insanity here, but the included solution is fast, cool-running, and safe — as long as you use OnePlus’ proprietary cable and brick.
Audio is a clear compromise. There’s a single bottom-firing speaker behind one of the two grills, with the other grill hiding the main mic. Loudness is good and output is clean, but this is a mono setup; the earpiece isn’t used as a second driver. Compared to the OnePlus 6, tuning shifts slightly and the removal of the 3.5mm jack has shaved loudness a bit when using the USB-C adapter. Clarity is still accurate, but this is not a media-first device.
OxygenOS: Clean, Fast, and Feature-Smart
If hardware is where OnePlus has started blending into the crowd, software is where it still stands out. The 6T ships with OxygenOS on top of Android 9 Pie, staying close to stock visually but layering in actually useful tweaks rather than bloat.
You get multiple navigation schemes: classic three-button, OnePlus’ full-gesture system (swipe up from center for home, hold for recents, side swipes for back), and Google’s Pie pill-plus-back layout. It takes some experimenting to find what your muscle memory likes, but at least you have options. The signature alert slider is still here too, with three stages (Ring, Vibrate, Silent) and some customization.
Gestures go beyond navigation. With the screen off, you can draw shapes to launch apps or control media (swipe two fingers for pause, < and > for track switching, letters mapped to apps). Double-tap to wake/sleep, three-finger swipe for screenshots, and flip to mute calls round out the list.
On the visual side you can switch between light and dark UI themes, choose system fonts, and set a global accent color that runs through quick toggles and menus. The notification shade can be pulled down with one swipe anywhere on the homescreen (once you enable it), and you can customize which status bar icons appear.
Under the hood, OxygenOS adopts Android Pie’s Adaptive Battery management to prioritize the apps you actually use. There’s also a Utilities section with Gaming Mode (notification and network prioritization rather than fake “turbo” performance), OnePlus Switch for migration with app-data support where allowed, and Smart Boost. Smart Boost preloads parts of frequently used apps into RAM to claim 5–20% faster cold starts, though that’s hard to quantify.
OxygenOS drops the true Always-On Display after earlier battery backlash, but keeps Ambient Display triggers (lift-to-wake, tap to show), basic clock styles, and the in-display fingerprint ring indicator. Google’s Digital Wellbeing stack (Wind Down, app timers) isn’t present at review time, but Pie’s core features largely are.
Cameras: Same Hardware, Slightly Smarter Software
Camera hardware is a rerun of the OnePlus 6. The main rear sensor is a 16MP Sony IMX519 (1/2.6″, 1.22µm) with f/1.7 optics and OIS at a 25mm equivalent. The secondary camera is a 20MP Sony IMX376K (1/2.8″) behind another f/1.7, 25mm-ish lens. In other words: no telephoto, no ultra-wide — just two similar FOV sensors primarily used for low-light stacking and depth.
The camera app keeps the usual swipe-based mode layout: photo, video, Portrait, and now a dedicated Night mode. A 1x/2x button simulates zoom despite the lack of optical reach; you’re basically just getting a crop with some sharpening and upscaling. There’s a surprisingly competent Pro mode with ISO 100–3200, 1/8000s–30s shutters, manual focus, white balance by Kelvin, exposure compensation, live histogram, RAW capture, and two Savable custom presets.
Daylight shots are very likable. Auto HDR delivers wide dynamic range, detail is good (if not the sharpest per-pixel), and noise is visible at 1:1 but controlled. Color rendering is a strong point: fall scenes look natural and vibrant without going cartoonish. In some sunrise-type scenes, the 6T actually pushes richer colors than the OnePlus 6, suggesting some extra scene tuning.
2x images are predictable: usable in a pinch, no better than a manual crop from the 1x shot. In low light, the main camera holds up well with preserved saturation, respectable detail, and sensible noise reduction. There’s a new Night mode that attempts multi-frame pseudo-long exposures. Handheld, it often softens images compared to the standard mode and doesn’t touch Huawei-level night processing. On a tripod, it can extend exposures to around 30 seconds and produce better results, but at that point you could just as well use Pro mode.
Portrait mode relies on the secondary camera for depth. Because both lenses are around 25mm equivalent, you need to stand close for headshots, which can get awkward. The upside is that separation is generally excellent and blur looks natural. It works nicely on pets and objects, not just people.
The 16MP front camera (f/2.0, reported ~20–25mm equiv.) delivers detailed selfies in good light. However, when HDR triggers, sharpness dips and shadows can crush into full black, especially in hair and other dark areas. Front Portrait mode works via software; edge detection is decent but halo artifacts around faces are still there.
Video tops out at 4K60 with bitrates up to ~121Mbps. You can shoot 4K30, 1080p30/60, and 720p, with 720p as the resolution for 480fps slow motion. Electronic stabilization is always on in 30fps modes and can’t be disabled; it helps handheld and walking shots but reduces fine detail and can look abrupt on pans. 4K60 and 1080p60 keep more detail and look sharper overall. Dynamic range and color are strong across modes.
Where the 6T Fits in 2018’s Flagship Crowd
The OnePlus 6T isn’t a dramatic leap over the OnePlus 6, and OnePlus doesn’t pretend it is. Same SoC, same cameras, similar design. The real upgrades are a larger and slightly nicer AMOLED with a less intrusive notch, a bigger battery with better endurance, and a genuinely usable in-display fingerprint reader. In exchange, you permanently lose the headphone jack, and you still don’t get stereo speakers, IP rating, wireless charging, or expandable storage.
What’s changed more than the phone is the market around it. Phones like Xiaomi’s Mi 8 and Pocophone F1 chase raw specs and aggressive pricing. On the other side, devices such as Samsung’s Galaxy S9+ and Note8 or Huawei’s P20 Pro bring IP ratings, telephoto and multi-camera setups, sharper displays, stereo speakers, and wireless charging — especially if you factor in price drops or carrier deals.
So the 6T stops being the obvious “flagship killer” default and becomes one more competent option in a crowded upper-mid/flagship space. If you value clean, fast Android with thoughtful extras, strong performance, a good AMOLED, and excellent battery life — and you can live without a headphone jack, IP rating, and stereo sound — the OnePlus 6T still makes a lot of sense.
Just don’t expect it to be the disruptive outsider OnePlus built its reputation on. That era’s over; this is OnePlus playing the mainstream flagship game on mainstream terms.
