How much live on average Xiaomi Redmi smartphones: factors, statistics and ways to extend the service life

Xiaomi Redmi smartphones have long gained a reputation for reliable and affordable devices, but even they are not eternal. The question “how long will my Redmi?” worries both those who are just planning to buy and owners of devices on the market. 2-3 The answer depends on a dozen factors, from the model and build quality to the user's habits and conditions of use. In this article, we will analyze the real life of Redmi smartphones according to service centers, analytics and tests, and also give specific recommendations on how to maximize the life of the device.

The average Redmi lasts 2.5 to 4 years, but that's a very low-end figure. 9A or Redmi 10C Rarely live to 3 years without serious lag or battery problems, while flagship Redmis are a few. K50 Pro or Redmi Note 12 Pro+ The main “killers” of smartphones are a degrading battery, overheating of the processor and software obsolescence (when the manufacturer stops releasing updates). We gathered data from service center reports, user surveys and wear tests to give an objective picture.

It’s important to understand that Xiaomi doesn’t disclose official data on the “shelf life” of its smartphones, but on indirect signs you can assess their potential. 1 This is the first sign that after 12-18 In the months ahead, capacity will start to drop markedly. Analysis of the used-tech market shows that most Redmis are sold hand-held through the market. 2-2.5 It's just when you start having problems with autonomy or performance, but that doesn't mean that the phone turns into a brick, because if you care for it properly, you can keep it going.

1.Statistics by model: how many live different series Redmi

The service life is highly dependent on the lineup of the device. Budget Redmi A and Redmi (digital) are designed for the first time. 2-3 The following are the most recent years of active use, whereas Note or K models can last a year or two longer (2021–2026 years).

Interesting fact: models with removable battery (for example, Redmi) 4X or Redmi 5A) On average, they served longer than 4 Modern Redmi with non-removable batteries are often sent to the scrap because of problems with autonomy: according to services, already through the use of a battery. 18 months, the capacity falls 15-20%, through 3 yearly 30-40%.

Another key factor is software updates. Xiaomi promises 2-3 the year of major updates and 4 The year of security patches for most models, such as the Redmi Note. 10 Pro (2021 last major update in the year 2023-The security patches have stopped coming out. 2026-That means that through 3 The phone is becoming software obsolete: new applications may run slower, and some features (such as banking services) will require a change of device.

2.Battery: Redmi's main 'weak link'

The battery is the first part that fails in the 90% According to the service centers, 1.5–2 The battery capacity in Redmi falls on 10-15%, through 3 yearly 25-35%. This means that the phone is running out of 1.5–2 This is faster than when you buy a Redmi Note. 11 hold on 1.5 with moderate use, then through 3 He'll be sitting down for the year. 8-10 hours.

The main reasons for the degradation of the battery in Redmi:

• 🔋 Frequent charging up to 100% - Lithium-ion batteries do not like full charge%.
• ⚡ Use of “fast” charging – models with support 33W/67W Battery wears out faster than devices with 18W.
• 🌡️ Overheating – if the phone is heated above 40°C (e.g., during games or solar charging), the chemical processes in the battery are accelerated, reducing its lifespan.
• 📵 Deep discharge – if you discharge Redmi “to zero” and leave it for a few days, the battery can lose up to 10% of capacity in one cycle.

How to check battery wear on Redmi?

1. Enter the code in the phone application: ##4636## → Select Battery Information.

⚠️ Note: If your Redmi suddenly turns off when you are 15-20% The charge is a sure sign of critical battery wear, in which case battery replacement (cost) 1 500–3 000 ₽ In the service, it will extend the life of the phone 1.5–2 year-end.

💡

If you rarely use your phone (for example, it’s a spare phone), keep it charged. 40-50% A full charge or discharge if stored long enough will kill the battery in a few months.

3.CPU and memory: when Redmi starts to "brake"

The second most popular reason to replace the Redmi is to slow down, even if the battery is fine, through the 2-3 The year users are faced with:

• 🐢 Hanging when opening apps (especially Instagram, TikTok, Google Maps).
• 🔄 Self-involved reboots.
• 🎮 Lagami in games (even those that used to go smoothly).
• 📱 Overheating of the shell at minimum load.

Causes of brakes:

1. Full memory: If the Redmi has less than 10% of the available space, the system begins to “hang”, especially on budget models with 32-64 GB of memory.
2. Data fragmentation: Over time, files are “scattered” from memory, and the processor takes longer to read them.
3. Outdated software: new versions of Android and MIUI Older chips (like the Snapdragon 660 in the Redmi Note 7) simply can’t cope with modern tasks.
4. Trojans and junk apps: Many users install programs from unverified sources that load the system with background processes.

How do you get the speed back?

Clear the cache (Settings) → Memory. → Clear the cache)

Remove unused applications

Disable autoboot programs (Settings) → Annexes → Auto-start)

Reset the settings to factory (saving the data!)

Update to the latest version (if available)

-->

If these measures don’t help, the problem is likely hardware wear. For example, budget Redmis often use eMMC memory (instead of faster memory). UFS), through 2-3 The year begins to “degrade”: the speed of reading / writing falls in the middle of the year. 2-3 In this case, you just have to change your phone or flash it to the lightweight version.

Xiaomi follows update policy similar to other manufacturers: 2-3 the year of the major updates and 4 It's a year of security patches, which means that 3-4 After the release, the model ceases to receive new features and fixes of vulnerabilities:

• 📅 Redmi Note 9 Pro (2020) – the last major update received in 2022, security patches ended in 2026.
• 📅 Redmi K40 (2021 — updates MIUI Ended in 2023, security patches are released until 2026.
• 📅 Redmi 10 (2021) – Support ends in 2026.

What's the risk?

• 🔒 Security vulnerabilities: Without patches, the phone becomes a target for viruses and hacking attacks.
• 📱 Incompatibility with new apps: for example, banking programs may require a fresh version of Android.
• 🎮 Problems with games: new versions PUBG Mobile or Genshin Impact may not be available.
• 🔧 Lack of support for new features: for example, the Redmi Note 8 Pro (2019) does not support Wi-Fi 6 or Bluetooth 5.2, even if it is possible to do so hardwarely.
