Samsung or Xiaomi: which is more reliable for a long time?

Choosing between Samsung and Xiaomi is not just a matter of design or price preferences; it is an investment in a device that should last at least 3-5 years without critical breakdowns, lags and software problems. Both brands occupy leading positions in the market, but their approaches to reliability are fundamentally different: the Korean giant relies on premium materials and long-term support, and the Chinese brand – on software optimization and repair availability.

In this article, we’ll cover 7 key aspects of reliability, from build quality and moisture protection to refresh rates and parts availability. Without marketing slogans, only facts, tests and data from real user reviews, service centers and independent labs. If you’re hesitating between the Galaxy S23 and Xiaomi 13 or between the budget Galaxy A54 and Redmi Note 12 Pro+, here’s the argument for making informed choices.

Spoiler: There is no clear winner. Reliability depends on the specific model, operating conditions and even the region of purchase, but after reading this, you will know exactly what to look for when buying to avoid the typical problems of each brand.

1.Build quality and materials: metal vs premium coated plastic

The first thing that catches your eye when comparing flagships is the materials used. Samsung in the top series (Galaxy S, Z). Fold/Flip) Traditionally uses aluminum frame with tempered glass Gorilla Glass Victus 2, a the back panel is either glass or premium plastic with matte coating (as in the Galaxy). S23 FE). Xiaomi in flagships (Xiaomi) 13 Ultra, Mix Fold 3) Also uses aluminum and glass, but often save on the thickness of the metal and the number of layers of protection.

The main difference is manifested in the budget and middle segment:

• 🔹 Samsung Galaxy A: plastic back panel, but with a reinforced frame and corrosion protection (Armor Aluminum technology in new models).
• 🔹 Xiaomi Redmi/Poco: Plastic is thinner and in some models (e.g. Redmi Note) 12) polycarbonate is used with imitation of glass, which scratches faster.

According to the results of bend tests (channel JerryRigEverything), the flagships of both brands can withstand a load of 12-15 kg without damage, but budget Xiaomi begin to creak already at 8-10 kg. At the same time, Samsung often suffers from unstick screen when falling (due to the adhesive layer, which eventually loses elasticity).

2. Protection against water and dust: IP68 vs "conditional moisture resistance"

Samsung’s official IP68 certifications are not just marketing: all flagships and most Galaxy A series models (starting with the A52) are tested for freshwater immersion to depths of 1.5 m to 30 minutes. Xiaomi also specifies IP68 for flagships (Xiaomi 13 Pro, Mix 4), but in fine print, it specifies: “protection does not apply to salt water, vapor and prolonged exposure to moisture.”

In the budget segment, the difference is critical:

• 💧 Samsung Galaxy A34/A54: full-fledged IP67 (dustproofing + submersion).
• 💧 Xiaomi Redmi Note 12 Pro+: splash-proof (IP53), This is often overlooked in advertising.

Real-world tests (such as those from Zack Nelson) show that Samsung is better at handling condensation inside the case after sudden temperature changes. USB-port after 1.5-2 years of operation.

⚠️ Warning: Both brands refuse warranty repairs for water damage, even if the device has a certificate. IP68. This is prescribed in the warranty conditions - protection is valid only when "accidental" moisture is ingested, and not when bathing with a phone.

3. Battery durability: fast charging vs slow degradation

Xiaomi is famous for ultra-fast charging (up to 210 watts in the Redmi Note 12 Discovery Edition), but this has the opposite side: high currents and heat release accelerate battery degradation. According to DXOMark tests, after 500 charging cycles, Xiaomi’s battery capacity decreases by 20-25%, while Samsung’s by 15-18%.

The secret of Samsung is conservative charging settings:

• ⚡ In flagships (Galaxy) S23 Ultra: Protect Battery is activated by default, limiting the charge to 85%.
• ⚡ In budget models (Galaxy) M34) 6000 mAh battery with slow charging (25 W) is used, which extends the life of the battery.

Xiaomi has Battery Health technology (in MIUI 14+), but it only works when manually enabled and isn’t always effective. For example, in Xiaomi 12T Pro after a year of use, many users complain of battery bloating when actively using fast charging.

💡

If you buy Xiaomi with 100+ watt charging, turn off the “turbo mode” in the settings and charge up to 80% – this will prolong the battery life by 30-40%.

4. Software Updates: 4 years vs 7 years of support

Samsung is clearly leading the way here. From 2022, all flagships and most Galaxy A series models are getting 4 years of major Android updates + 5 years of security. For comparison, even the top Xiaomi (Xiaomi 13 Ultra) get only 3 years of Android and 4 years of patches.

But there are nuances:

• 📱 Samsung is also updating budget models (Galaxy) A14 Android 14 was received, but with a delay of up to 3-6 months.
• 📱 Xiaomi is releasing new versions faster MIUI, but often without critical corrections (for example, bugs with autobrightness in the MIUI 14 not eliminated six months).

According to StatCounter, after 3 years of use, 78% of Samsung smartphones are running the current version of Android, while Xiaomi has this figure - 42%.

⚠️ If you plan to use your phone for more than 3 years, check the model on the Samsung Security Updates website. MIUI Redmi Note 11 will not get Android 14, although it was released in 2022.

5.Service and repair: official centers vs. "grey" parts market

Samsung’s global network of service centers is one of the key advantages of the brand: in Russia and the CIS, official workshops are in 80% of cities with million inhabitants, and spare parts (screens, batteries, cameras) are delivered directly from the factory. The average repair time is 3-5 days. Xiaomi’s situation is worse: official centers are 2-3 times less, and many models (for example, Poco F5) have to wait 2-3 weeks for spare parts.

The repair prices are also different:

• 💰 Replacement of the Galaxy screen S23: ~25 000 ₽ (original).
• 💰 Replacement of the Xiaomi 13 screen: ~18 000 ₽, They often offer unoriginal matrices.

Xiaomi's main problem is that it doesn't have unified parts, like the Redmi Note 12 speaker, which is not a good fit for the Redmi Note 12 Pro, even though they look identical, which makes repairs more difficult and expensive.

6.Real user reviews: what problems are more common

An analysis of complaints on forums (4PDA, Reddit, Mi Community) shows the typical problems of each brand:

Samsung:

• 🔥 Overheating in budget models (Galaxy) A14) long-load.
• 📉 Burnout OLED-screens (yellow spots) through 2–3 Years (characteristic of the Galaxy) S20/S21).
• 🔊 Problems with speakers after dust hit (Galaxy) S22 Ultra).

Xiaomi:

• 🐢 Slowdown MIUI through 1.5–2 In the year (especially in the Redmi). 6/8 GB RAM).
• 📡 Bad signal reception in metal housings (Xiaomi) 12S Ultra).
• 🔋 Battery bloating when using fast charging (>65 W).

According to the GSMArena survey (2023 year), 64% Samsung owners did not face critical breakdowns in the first 3 This year, Xiaomi has this indicator — 48%. However, in the budget segment (<25 000 ₽) The difference is leveled: both brands have approximately the same level of complaints (~30–35%).

💡

If you choose between flagships, Samsung is more reliable for the long term. In the budget segment (Galaxy A vs Redmi Note), the difference is minimal, but Samsung has better support and repair.

7. Which brand to choose in 2026: the final checklist

To make the final choice, answer the following questions:

1. Budget budget: ✅ Up to 30,000. ₽ → Xiaomi Redmi Note 13 Pro+ (better camera and charger). ✅ 30 000–50 000 ₽ → Samsung Galaxy A54 (longer). ✅ 80 000+ ₽ → Samsung Galaxy S23 (7 years of updates).

Priorities:

• 📸 Photo/video → Samsung (Best Processing).
• ⚡ Fast charging. → Xiaomi (200 W vs 45 W at Samsung).
• 🛡️ Durability → Samsung (IP68, 7 years of support).
• Region: In Europe and the US, Samsung is winning on service; in Asia and India, Xiaomi is cheaper to repair.

If you want a phone for 5 years without problems, go with Samsung (even the budget Galaxy A34 will last longer than the Redmi Note 12 Pro+).If you want maximum performance for less money and are willing to put up with more frequent updates, Xiaomi will be the best choice.
