Xiaomi Mi MIX 3 vs Oppo Find X vs OnePlus 6: Price in India, Features, Specifications Compared

The Mi Mix 3 comes with wireless fast charging and a 10GB RAM option, but is it better in every aspect than its competition? Read on to find out.


The much-awaited Xiaomi Mi MIX 3 has been unveiled in Beijing today. It flaunts an impressive bezel-free display and a sliding mechanism. The screen estate is as good as it gets, with 93.4 percent screen-to-body ratio. Certainly, this will be the USP of the handset, as other specs are not exactly startling. There is, however, 10GB of RAM, the first for any smartphone in the world, but it is restricted to the pricey special edition. The much-hyped 5G modem is also not yet here, with Xiaomi promising the 5G variant to launch for the European market next year.

So, how much of a pull does the new Xiaomi flagship carry? Is it good enough to take on flagship handsets that offer excellent bezel-less displays? In this comparison, we will pit the Mi MIX 3 against the Oppo Find X (Review) and the OnePlus 6 (Review). Read on to find out where the new phone takes the lead and where it lags behind.

Xiaomi Mi MIX 3 vs Oppo Find X vs OnePlus 6: Price in India

The India pricing of the new Mi MIX 3 has not been made official yet, but the China pricing gives an indication. The flagship device has been launched at a starting price of CNY 3,299 (INR 34,800 approx) for the 6GB RAM variant, which comes with 128GB of internal storage. Chinese buyers can also go for two 8GB RAM models, one with 128GB storage for CNY 3,599 (INR 37,900) and the other with 256GB for CNY 3,999 (INR 42,100). The 10GB RAM variant that had made so many headlines is called ‘Palace Museum’ special edition, and it gets 256GB of internal storage. This model has been introduced for CNY 4,999 (INR 52,700).

In comparison, the pricing of the OPPO Find X is simple but not equal. There is only one variant: 8GB RAM+256GB of storage, and it sells exclusively on Flipkart for INR 59,990.

The OnePlus 6 (6GB RAM+64GB storage) sells for INR 34,999. You can buy the handset with 8GB RAM+128GB storage for INR 39,999. The 8GB RAM+256GB storage variant is priced at INR 43,999. The latter, through offers presently on Amazon, is selling for a flat discount of INR 5,000, but stocks are running out.

As you can see, the Mi MIX 3 has a pricing advantage, offering 128GB of storage at a price point of approximately INR 35,000, but we will have to wait for a while to have the India pricing confirmed.

Xiaomi Mi MIX 3 vs Oppo Find X vs OnePlus 6: Display, Build

The Xiaomi Mi MIX 3 is a good looking phone, with a mechanical pop-up slider for the front camera, and a commendable 93.4 percent screen-to-body ratio. However, the Oppo Find X is still slightly better, with a 93.8 percent screen-to-body ratio for its bezel-free display. The OnePlus 6 has a notch, so it gets about 84 percent screen-to-body ratio. Both the Mi MIX 3 and the OnePlus 6 have a rear-mounted fingerprint sensor while the Oppo Find X ditches the security feature for a 3D IR Face Unlock mechanism.

All three handsets offer a premium bezel-free experience. The OnePlus 6 is the lightest of the three, weighing just 177 grams, while the Mi Mix 3 is somewhat heavy at 218 grams. Overall, we prefer the design of the OPPO Find X, thanks to the pop-up mechanism which offers much more than just hiding the camera. All three handsets look premium, but the Oppo Find X has a higher aesthetic appeal to it.

The display of the Mi MIX 3 is nothing out of the ordinary for the new flagship handset, with a 6.39-inch Super AMOLED unit with Full HD+ screen resolution and 403ppi. The OnePlus 6 has a 6.3-inch Optic AMOLED display with Full HD+ resolution and 402ppi, and the OPPO Find X has a 6.42-inch AMOLED display with Full HD+ screen resolution and 401ppi. The screen on the OPPO Find X appears the best.

Xiaomi Mi Mix 3 vs Oppo Find X vs OnePlus 6: Performance

All three devices in this comparison are powered by the same Qualcomm flagship Snapdragon 845 chipset, with Android 8.1 Oreo-based skin on top. We will have to try out the handset or wait for user reviews to know whether or not the new 10GB RAM in the Mi Mix 3 makes any difference to the device performance.

Xiaomi Mi Mix 3 vs Oppo Find X vs OnePlus 6: Camera

The Mi Mix 3 has the advantage of four camera sensors, with a 24MP+2MP setup for the selfie camera placed in the slider, and a 12MP+12MP vertical dual camera setup. The OPPO Find X sports a 25MP front camera and a 16MP+20MP rear camera, both of which are set in the motorized slider. The OnePlus 6 is more conventional in this regard, with a 16MP front shooter fitted in its notch, and a 16MP+20MP rear dual camera.

You get a wide-angle lens with OnePlus 6 and Mi MIX 3 both, but the latter has a telephoto lens for its second 12MP sensor. The Mi MIX 3 gets 4-axis OIS, similar to the two other phones. The Mi MIX 3 also gets dual-pixel phase detection autofocus, while the other two have regular PDAF. All three handsets use large pixels for their cameras and shoot 4K videos, but the Mi MIX 3 gets ultra slow-motion HD video recording at 960 frames per second. The OPPO Find X has better image quality, both under good light and low light, but the OnePlus 6 shoots better videos.

The Mi MIX 3 comes with 10W fast wireless charging, as well as QuickCharge 4.0. All three handsets get Type-C USB connectors, and the OnePlus 6 and Mi MIX 3 comes with 20W fast charging support. The battery on the Oppo Find X is the largest at 3730mAh, followed by the OnePlus 6 (3300mAh) and the Mi Mix 3 (3200mAh). The Mi MIX 3 gets dual-band A-GPS, and all three devices get dual-band WiFi as well as Bluetooth 5.0 Low Energy. Only the OnePlus 6 carries a 3.5mm headphone jack.
