Comparison of the OnePlus 6T against the OnePlus 6

Design and screen: ruled by the notch

They are all phablets with elegant design in each section. The only one that is not infected with the famous notch is the Galaxy S9 Plus. Thus, the other mobiles resemble the iPhone X by having this feature on the screen.

The largest screen is that of OnePlus when acquiring a 6.28-inch screen. Then we have the recently presented Xiaomi Mi 8, the Galaxy S9 Plus and finally the P20 Pro. However, the difference is very little and if you want a terminal with a large screen you will like any of them.

Hardware: don’t lack power

Each phone has a different chip for its power. But, without a doubt, it could be said that the Snapdragon 845 of the Mi 8 is the one that stands out the most. This chip scored 301,000 on AnTuTu and has a structure that allows it to fly through every task with the device. Then we have an Exynos 9810 (from the Galaxy S9 Plus), a Kirin 970 (for the P20 Pro), and a Snapdragon 835 (from the OnePlus 6). In terms of power, none of them lack anything and you will not have problems running heavy applications either..

On the other hand, in the RAM memory part, there are no differences when having 6 GB versions, although the OnePlus 6 and the Xiaomi Mi 8 have an 8 GB version. Furthermore, regarding the internal storage, we find versions ranging from 64 GB to 128 GB (256GB for the Mi 8).

Camera: the kings of the photographic section

One of the topics that I like the most about the comparisons is photography. In this sense, you are in front of the mobiles with the best camera on the market. And I’m not saying it, because the ratings have been published by the gentlemen of DxOMark. In these laboratories it has been revealed that the P20 Pro continues to lead with 109 points. Then we have the Galaxy S9 and Xiaomi Mi 8, both scoring 99 to rank fourth and fifth respectively.

Huawei vs US, former Google CEO reveals reason for ban

The review of the OnePlus 6 camera has not yet been published, but we have already seen how this mobile takes photos and videos and the truth is that the results are very good. In conclusion, each and every one of these devices have good cameras so you can take photos and videos in all scenarios without problems.


Each and every one of these terminals have the NFC payment system and USB-C. If we talk about a notable difference, it should be noted that the Xiaomi Mi 8 has arrived with dual GPS that allows it to have a minimum margin of error of only 30 cm. Thanks to this, we will be better located when we go to an address by car, bicycle or even on foot.


This is where the balance is a little unbalanced. Here we have all the prices of these terminals:

  • Xiaomi Mi 8 – the cheapest of all: it has been presented for the sum of 360 euros in its 6 GB + 64 GB version.
  • One Plus 6: It is available on Amazon from 519 euros.
  • Samsung Galaxy S9 Plus: available on Amazon for the sum of 667 euros.
  • Huawei P20 Pro: from 682 euros on Amazon.

At this point it should be noted that the Mi 8 will rise in price for shipping, customs, etc. However, it is still an offer that will not be overlooked when it can be purchased.


Whichever way you look at them, here you have the best in camera, design and hardware. Each mobile boasts excellent design and good performance. Of course, if you want to buy the cheapest one on the list, you will have to wait a couple of days. Meanwhile, you can evaluate if you buy any of the other 3. Here you will see the link to buy them from Amazon at a good price.
