Oppo or Xiaomi: Which is better in 2021?

Choosing a new smartphone in 2021 has become one of the most difficult tasks for the average consumer, especially when two tech giants, Oppo and Xiaomi, are on the scale. Both manufacturers have gone from making budget copies to innovation leaders offering flagship specs at affordable prices. In 2021, competition between these brands reached a peak: Xiaomi aggressively captures markets by introducing new processors, while Oppo bets on premium, design and collaboration with Leica or Hasselblad in cameras.

A potential buyer needs to understand that behind the look and feel of the features hide vastly different hardware and software development philosophies. Xiaomi has traditionally offered more hardware power for the same money, often sacrificing some aspects of optimization, while Oppo focuses on stability, build quality and advanced photo processing algorithms. This year, not only the gigahertz of the processor, but also charging speed, screen quality and update support have been key factors.

In this article, we will conduct an in-depth analysis to determine which smartphone will be more practical in real life. We will look not only at dry benchmark numbers, but also at the everyday experience of using MIUI and ColorOS shells. The answer to the question of whether Oppo or Xiaomi is better in 2021 depends on your priorities: whether you want maximum performance in games or more aesthetics and quality of portrait shooting.

Brand philosophy and market positioning

Understanding a company’s corporate DNA helps predict what to expect from their device. Xiaomi positions itself as a technology company committed to making cutting-edge innovation accessible to everyone. In 2021, this translates into the use of top-end Snapdragon chipsets even in the mid-range segment. Their approach is often called the “flagship killer,” where technical specifications prevail over the exterior. Xiaomi’s marketing strategy is built on creating hype around new releases and selling devices at a minimal margin, offsetting this by the smart home ecosystem.

Oppo, on the other hand, has always been a focus on style, design and quality. In 2021, they have strengthened their position by introducing their own image processing chips, such as the MariSilicon X. Their devices often look more elegant, use expensive materials like ceramic backs and curved screens. If Xiaomi is screaming for power, Oppo is whispering about premium, a difference particularly noticeable in the way companies approach interface creation and preinstalled software.

⚠️ Warning: When buying Xiaomi devices with global versions, carefully check the firmware region. In 2021, the cases of supplying devices with Chinese firmware, re-flashed to global, which can lead to problems with notifications and banking applications, have increased.

Importantly, both brands are part of huge conglomerates (BBK Electronics for Oppo and the Mijia ecosystem for Xiaomi), giving them access to cutting-edge display and sensor manufacturing technologies.However, if you value minimalism and clean interface, Oppo may seem friendlier, while customization fans will choose Xiaomi.

Comparison of hardware platform: processors and performance

When it comes to hardware, Xiaomi is often on the winning side of the 2021 Mi 11 flagship lineup and the Redmi K40 series (known globally as the Poco F3) first to gain access to the Snapdragon 888.This has provided them with a whopping performance boost in synthetic tests. Xiaomi engineers aren't afraid to implement aggressive cooling systems to squeeze the most out of the processor, making their smartphones preferred for mobile gaming.

Oppo was also betting on balance the same year, with its flagship Find X3 series also getting powerful chipsets, but the priority was energy efficiency and heat. In the mid-size Oppo often uses MediaTek Dimensity processors, which in 2021 proved very good, especially in artificial intelligence tasks. However, when comparing the frontal power in games with high graphics settings, Xiaomi devices often show more stable FPS.

Both brands moved to LPDDR5 and UFS 3.1 in the flagship segment in 2021, but Xiaomi offers 12GB of RAM at a price where Oppo only offers 8GB. This is a critical parameter for those who keep dozens of applications open.

• 🚀 Xiaomi: Leadership in the benchmarks AnTuTu, aggressive overclocking of the processor, the best configuration in the basic versions.
• 🎨 Oppo: Optimization for everyday tasks, less trottling (reduced frequencies) with prolonged load, stable operation GPS.
• 🔋 Power consumption: Oppo often wins in screen time by sacrificing peak power.
• 🎮 Xiaomi offers special game modes and triggers in some models.

So for hardcore gamers, the choice in 2021 is leaning towards Xiaomi.But if you want a phone that just opens apps quickly and doesn't heat up in your pocket, Oppo's engineering solutions may prove more enjoyable in the long run.

Displays and multimedia capabilities

The screen is a window into the digital world, and here both manufacturers in 2021 showed outstanding results. Xiaomi in the Mi 11 model used one of the best AMOLED arrays from Samsung with WQHD+ resolution and refresh rate of 120 Hz. Color reproduction is set to maximum brightness and saturation, which is liked by content lovers. However, color calibration sometimes goes to “cold” tones, which requires manual adjustment in the engineering menu.

Oppo, in its flagship Find X3 Pro, has gone a step further by introducing a 10-bit panel with support for a billion shades. This provides incredibly smooth gradients and natural color reproduction close to professional monitors. Their O1 Ultra technology allows low-quality content to be scaled to 4K in real time. For video and photo viewing, Oppo screens in 2021 are considered reference.

💡

When choosing a smartphone, look for PWM (pulse-latitudinal modulation) technology. Oppo OLED screens often have higher PWM frequencies, which reduces eye strain at low brightness.

The sound system is also important. Xiaomi is partnering with Harman Kardon to deliver powerful and bass sound, though sometimes sacrificing mid-frequency detail. Oppo uses stereo speakers built into the screen design to give a more uniform and clean sound. In 2021, the presence of a 3.5mm connector became rare, and both brands have almost abandoned it in flagships, relying on Bluetooth 5.2 and aptX HD codecs.

⚠️ Attention: High refresh rate (120Hz) screens consume a lot of battery.If autonomy is a priority, consider reducing the frequency to 60Hz in the screen settings → Frequency of update.

Cameras: The Battle of Algorithms and Sensors

Photography is a battleground where Oppo traditionally feels like a fish in the water. In 2021, the Find X3 series introduced the concept of "two main cameras": wide-angle and ultra-wide-angle, both with Sony IMX766 50MP sensors. This means that "wide" shots are as good as the basic ones. Oppo's algorithms are famous for their natural skin color reproduction and excellent dynamic range.

Xiaomi responded by introducing the Mi 11 Ultra with a giant GN2 main sensor and a periscopic telephoto lens. While Oppo is winning in portraits and nighttime photography thanks to software, Xiaomi is taking in megapixels and zooming capabilities. But Xiaomi's software processing sometimes sins with excessive noise cancellation and skylighting.

Video is another strong point for Oppo: Stabilization in their devices is softer and more predictable; Xiaomi offers 8K recording but with strong time and heat constraints; Oppo is offering a more off-the-shelf product for bloggers and content creators in 2021.

• 📸 Portraits: Oppo better blurs background and treats skin.
• 🔭 Xiaomi offers a greater optical and digital approximation.
• 🌙 Night: Parity, but Oppo handles white balance better.
• 🎥 Video: Oppo wins by better stabilisation and microphones.

Software: MIUI vs ColorOS

This is perhaps the most subjective but important choice criterion: Xiaomi’s MIUI 12/12.5 shell in 2021 was very functional but overloaded. Huge setups, second spaces, hidden apps are a geek paradise. However, MIUI has often been criticized for the abundance of advertising in system applications (even after buying an expensive phone) and instability in early firmware versions. The interface can seem complicated for older people.

Oppo’s ColorOS 11/12 (based on Android 11/12) was considered one of the smoothest and most stable in 2021. It offers deep customization capabilities (AOD, widgets, icons), but does so in a more elegant and unobtrusive way. ColorOS animations are often compared to iOS for their smoothness. Advertising in Oppo’s system applications is much less common and easier to turn off.

⚠️ Attention: B MIUI The system of energy saving, which can "kill" the background processes of messengers, is aggressively working. → Permissions to not lose messages.

In terms of updates, Xiaomi in 2021 began implementing a policy of 3 years of Android updates for flagships, catching up with Oppo. However, the speed of release of security updates from Oppo is often faster. If you like to “dig” in the system and install mods – you go to Xiaomi. If you need to “on and forgot” – Oppo will be more comfortable.

Autonomy and charging technologies

In 2021, the charging power race took a new level. Oppo is a pioneer of SuperVOOC technology. Their flagships supported 65 watts and even 125 watts (in concepts), which allowed the phone to charge from 0 to 100% in less than 30 minutes.

Xiaomi has kept up with 67W and 120W (HyperCharge) charging in the Mi 11 Ultra and Mi 10T Pro models. The speed is comparable to Oppo, but implementation often requires the use of a specific cable and a unit from the kit. Battery capacity for both brands in 2021 was standardized at 4500-4600mAh for flagships and 5000mAh for the mid-range segment.

Importantly, wireless charging in 2021 has become the standard for both brands’ flagships, with power up to 50 watts. However, Oppo has also implemented reverse wireless charging with higher efficiency, allowing you to charge headphones or watches simply by putting them on the back of the phone.
