Pros
- Very good charging performance
- Strong performance in on the go testing
- Lower consumption than the competition for phone calls
Cons
- Higher consumption than the competition for music streaming
- Higher consumption than the competition when the smartphone is charged but still plugged in
The OnePlus 8T showed excellent performance in our charging tests, going from a completely empty to a completely full battery in under 40 minutes, thanks to its fast 65W charger, which also brought it high marks in our 5-minute quick boost tests. However, its global battery performance was undercut by somewhat limited autonomy, with battery life lasting a bit less than two days under average conditions. As for specific use case comparisons, it did well when making phone calls and when streaming video, but did quite poorly when streaming music.
We compared the OnePlus 8T’s performance in several key categories with two other high-end devices, the Xiaomi Mi 10T Pro 5G and the Oppo Find X3 Lite; battery capacity, charger, display type and resolution, and processor specifications for all three devices are shown in the table below.

Somewhere-in-the-Middle
In-Display Fingerprint Reader
I’ve got to be straight with you guys – this in-display fingerprint reader isn’t that great. I’m sure this will be the future of fingerprint readers and they’ll continue to get better, but the OnePlus 6T’s leaves a lot to be desired.
To recap, the big innovation for the 6T is the move into in-display fingerprint readers. The fingerprint reader sits below the front display and uses light to scan your finger in order to match-up to one you’ve trained it to recognize. It works, just not that quickly or reliably, plus the light beam it requires to work can be obnoxious in dark situations.
My issues here are that in order to work, you have to first wake the phone on some level. Unlike the fingerprint reader on the backs of phones, which let you scan your finger when the phone is locked and asleep, an in-display fingerprint reader needs the display to wake up. You can do this somewhat easily by telling the 6T to wake when you move, lift, or tap the phone. With that feature enabled, it uses a half-baked always-on display type of experience to at least show the clock, notifications, and get the fingerprint reader ready for reading.
Now, I’ve retrained the fingerprint reader on my 6T 2-3 times now and they still don’t read every single time with the quickness I’m used to. The angle of my finger placement seems obnoxiously important, it struggles to read as the room darkness around you increases, and more often than not I feel like I’m leaving my finger on the screen for seconds at a time hoping it scans properly. I actually think that the performance of it worsened after the phone’s first update, which was supposed to improve the fingerprint reader.
You guys know that I’m all for technology that takes steps away from normal patterns and removes barriers while maintaining security. This particular fingerprint reader does not do that just yet, unfortunately.
So look, I like the idea of an in-display fingerprint reader, but I think I’d rather just reach to the back of a phone to unlock with a traditional reader until these in-display joints get better.
This OnePlus 6T camera might not be very good either. The camera app is slick and has a good amount of features, though, so there’s that.
And as far as the app itself goes, it really does have everything from auto and portrait modes to time lapse, slow motion, and pro. The video can be cranked all of the way up to 4K at 60fps, Google Lens is built in, it launches quickly, and I didn’t have any issues with FOCUS. I have no complaints in the 6T camera software department.
But look at these photos real quick.
Is it me or do these all just look dull, lifeless, and with horrible processing? I’m probably spoiled coming from the Pixel 3 right before this, but this is not very impressive for a phone with specs that look as they do on paper. The combination of 16MP and 20MP shooters at f/1.7 sounds nice, right? What are they doing together, though? What benefit are we getting if this is what they are producing?
Here’s an example of a Pixel 3 photo next to a OnePlus 6T photo. See how the exposure is out of whack on the 6T and doing this hazy background texture, while also going nuts with edge processing on everything not in FOCUS? And the red of the earbuds case is washed out, not the vibrant red that it really is and that you see in the Pixel 3 shot.
Pixel 3 vs. OnePlus 6T
Look, the bells and whistles are there and OnePlus will likely continue to incrementally improve the camera experience. I just don’t know that you should ever expect greatness from this setup. Just know that you are buying the OnePlus 6T because of price, performance, software, and design, not because it has the best camera.
The Not-so-Good
It’s not really an upgrade
I know that OnePlus is trying to bring us the future with its in-display fingerprint reader, reducing display notches, and killing headphone jacks, but this phone really doesn’t feel like any sort of upgrade over the OnePlus 6, which was released only a few months ago. This is very much in line with the 3T release after the 3, rather than the 5T after the 5 – that’s not necessarily a good thing. I’d argue that if you aren’t on Verizon and want a OnePlus phone, that you should consider the 6. The 6 has a better fingerprint reader, a headphone jack, and comes in a stupidly pretty red color. It has the same software experience and camera, is slightly smaller, and is available with the same RAM and storage setups. It also starts at 20 less.

If your budget is around 600, the OnePlus 6T is going to be a great buy. This is the value phone still to this day, and not just because it’s cheaper than the phones it competes with. The OnePlus 6T is legitimately a good phone with impressive hardware, almost all the specs you need, great software and performance, a solid display, and battery life that few can match. It now works on Verizon, is sold at T-Mobile, and has an in-display fingerprint reader, which is super cool.
Now, that new fingerprint reader tech is somewhat frustrating to use, the headphone jack is gone, and the camera isn’t even close to being the best in the business, but the rest probably makes up for those areas. Again, this is a sub-600 phone. For that price, what the 6T offers is nothing short of amazing. Go buy one, unless your budget is sky high and you can afford a Pixel 3 XL or Galaxy Note 9.

Battery: Enough power to last all day and then some
The battery life of the OnePlus 6T is fantastic. It comes with a beefy 3,700mAh battery, which was more than adequate to run for a couple days of light usage during our hands-on testing. In a stress test with the screen on, and both the Wi-Fi and mobile data connections active, it lasted about 10 hours. With airplane mode enabled, it lasted an impressive 16 hours. The phone supports fast charging (5V/4A), if you use the included charger or another compatible charger, but it doesn’t support wireless charging.
Software: Android Pie with custom OxygenOS
The OnePlus 6T comes with Android Pie, but it isn’t fully stock. OnePlus uses their own OxygenOS, which is basically Android with some extra functionality stacked on top. We typically prefer the stock Android you get from Google and Android One devices, but OxygenOS actually provides a surprisingly smooth experience.
If you’ve used Android Pie before, you’ll find everything pretty much where you would normally expect it, especially when it comes to system menus. Most of the tweaks you get with OxygenOS are aimed at improving productivity, like swiping left from the home screen gets you a list of your most recently used apps, a place to take quick notes, useful information about battery life and storage space, and more.

OnePlus is pretty reliable about pushing the monthly Android security updates, and they’ve included some nice features like Adaptive Battery controls and Night mode. It also includes a Game mode that activates whenever you launch a game app, giving you the option to prevent alert interruptions and lock in your screen brightness while you’re playing.
Price: Fantastic value for the money
Price is where the OnePlus 6T really shines. In its least expensive configuration, with 128GB of storage and the glossy finish, the 6T has an MSRP of 549. If you want the matte finish and 256MB of storage, it goes for 629. That might not be cheap compared to mid-tier phones like the Nokia 7, but this isn’t a mid-tier phone. The OnePlus 6T packs flagship-level specs and features at a much lower price. The bottom line is that the 6T gives you a whole lot of phone for the money.
The OnePlus 6T is something of a strange beast when it comes to comparing it to the competition. If you compare it to flagship phones like the Google Pixel 3XL, iPhone XS, and Samsung Galaxy S9, it falls short to each one in categories like the pixel density of its display, the camera, sound quality, and it doesn’t support wireless charging. But those phones cost hundreds of dollars more than the 6T. In terms of specifications and raw performance, the 6T compares very favorably to what it’s competing against and puts mid-range phones to shame.

Premium performance and style without an inflated price tag.
If you’re in the market for a high-end flagship phone, but you want to save some money, the OnePlus 6T is the phone to buy. If you’re in the market for a mid-tier phone, and looking to spend on the higher end of that range, it’s also worth looking at the 6T as an upgrade, though you can find cheaper options.
