Comparing Samsung S9+ with Xiaomi Mi Mix 2S

Samsung S9+ vs Xiaomi Mi Mix 2S

As we all know, one of the 2018 Xiaomi flagship was the Xiaomi Mi Mix 2S, a device that was unveiled in Shanghai on March 27th and which is located at the top of the Xiaomi product range, destined to compete with the Big Apple or Samsung terminals.

The Galaxy S9 + shares the same fundamental design as its predecessor, the Galaxy S8 +, with Samsung focusing on improving the camera to consider that the device was perfect in everything else.

Xiaomi is carrying out a similar strategy with its new device, the Xiaomi Mi Mix 2S, which has the same design as the Mi Mix 2 from last year, but with an updated chip set and a new dual camera configuration in the part later.

Comparing the versions available so far, Galaxy S8 + with the Mi Mix 2 from ast year, we discover that Samsung is still a tad ahead, but by very little difference. The Chinese manufacturer is committed to improving the quality of the camera on their phones this year, and we saw the same in the budget segment with the Redmi Note 5 Pro.

With the Mi Mix 2S, Xiaomi is promoting a new AI mode that automatically selects the best shooting mode according to the lighting conditions. Let’s see if the improvements make Mi Mix 2S stand firm against the Galaxy S.

The Mi Mix 2S is the most refined Xiaomi phone yet, and that is a guarantee of quality. Xiaomi defined the hardware part of the equation from the beginning, and that was a great reason for the brand’s success. And although MIUI had much in its favor, recent iterations have felt inflated, with basic functions such as push notifications that have been broken in the initial compilations, an aspect in which Xiaomi has room for improvement.

Fortunately, Xiaomi solved many of these problems in MIUI 9.5. Finally, the ROM looks like a joint effort and not something that has been added to the new features after each update.

For most of you reading this, the default option would be the Galaxy S9 +. The Mi Mix 2S is limited to China for the time being, which makes it difficult to find, and although the phone is ready to reach several Asian countries in the coming months, it will not be available in most Western markets. At least in the short term.

Xiaomi now has a presence in Europe, and it is likely that the Mi Mix 2S makes its debut in Spain, but apart from that, you will have to go to the resellers route to put your hands on the phone if you want to use it immediately.

For around the $ 550 mark, there’s a lot to like in the Mi Mix 2S. The hardware is evocative (as always), and Xiaomi finally solved long-standing problems at MIUI. Then there is the camera, which is a significant update compared to the previous Xiaomi flagships. The phone is a legitimate contender for the best device in this category, but if you’re looking for a complete option, the Galaxy S9 + is the best option, especially if you’re in the USA or Europe, but as we say, the difference between the two is not at all broad.

Something curios with Samsung is that the battery life has degraded from the Galaxy S8 series, and seeing that the Galaxy S8 + is still available, sometimes it is even a better option to take the flagship from last year. The camera on the Galaxy S9 + is better, and you get two, but it’s not worth the extra for the new S9 + commands at this time.

As for the Mi Mix 2S, if the phone starts anywhere around the 400 euro mark to change like its predecessor, it has the potential to become one of the best smart phones available.

Where they tie

Both phones also have top performance: you will not find delays in any of the devices. The Galaxy S9 + comes with 6 GB of serial RAM, like Mi Mix 2, and both phones can be configured with up to 256 GB of internal storage. The 256 GB option in the Mi Mix 2S comes with 8 GB of RAM, as well as the global LTE bands: the standard variant has limited LTE connectivity to Asian markets.

The similarities continue also on the software side: both phones come with Oreo from the factory. The Mi Mix 2S introduces MIUI 9.5, and Xiaomi has significantly improved stability and solved numerous errors. Samsung Experience 9.0, meanwhile, is almost identical to what we saw in the S8 + last year. I give MIUI the advantage on this front just because of the improvement in the performance of the previous iteration.

Where is Xiaomi better?

  1. The ceramic back gives Mi Mix 2S additional resistance to falls, and does not scratch so easily.
  2. The Mi Mix 2S also feels better to hold thanks to the subtle curves in the back and the smaller form factor of 5.99 inches. The 6.2-inch 18.5: 9 panel on the S9 + is a bit large, and the narrow chassis combined with the high screen makes the phone difficult to handle.
  3. It is also easier to reach the fingerprint sensor in the Mi Mix 2S: it is located where the finger usually rests on the back, so it is not necessary to turn the hand to access it.
  4. The 3400 mAh battery, slightly lower than the 3500 mAh battery of the Galaxy S9 + cheats. However, the FHD + panel and the MIUI battery saving optimizations make the phone last much longer than the S9 +. The difference is particularly noticeable when using mobile data throughout the day: the Galaxy S9 + barely managed to last more than 14 hours, while the Mi Mix 2S delivered more than 20 hours of battery life.
  5. The Mi Mix 2S also has the advantage when it comes to charging.
  6. The price, practically half.

Where the Samsung wins

  1. The Samsung AMOLED screen. The colors are vibrant and saturated, the viewing angles are excellent and the panel is certified for HDR10.
  2. The speakers of the Samsung get more details and the sound study is wider. The built-in speaker in the S9 + is one of the best currently, and a significant improvement over last year.
  3. The Galaxy S9 + also wins as it has a 3.5mm connector, a painful omission in the Mi Mix 2S.
  4. Water resistance: Mi Mix 2S is rated for occasional water splashes, but will not survive if it falls in the pool. The Galaxy S9 +, meanwhile, is IP68 certified, which makes it more immune to the elements.
  5. The Samsung is on the Samsung Pay platform.
