Redmi smartphones attract with their competitive prices and decent performance, but no device is immune to malfunctions. Accidental drops, weakening battery, cracked screen, or unstable connection, many users regularly encounter the same issues. Identifying these recurring failures not only helps to better understand the average lifespan of a device but also to anticipate repair costs or actions to take to limit damage.
Repair center statistics show that nearly a third of repairs involve the screen. Cracks, loss of touch sensitivity, or the appearance of colored lines are common symptoms.
The main causes are obvious: dropping on a hard floor, excessive pressure in a tight pocket, or exposure to moisture. But there are also cases of failure without impact: software update disrupting display management, manufacturing defect on certain series, or digitizer failure.
A broken screen can cost 40 to 120 euros to replace depending on the model. It’s a significant investment, especially when the price of a new phone sometimes barely reaches 200 euros. This explains why some users prefer to buy a new device rather than repair it.
After 18 to 24 months, many users notice that the battery loses autonomy. This phenomenon is linked to the natural aging of lithium-ion cells. But with Redmi, this problem is exacerbated by several factors:
A tired battery manifests as a charge that stagnates, autonomy halved, or a swollen case. The latter case is dangerous as it can damage other internal components.
The average cost of a battery replacement varies between 20 and 50 euros in France. To extend its lifespan, it’s better to limit full charges and avoid intensive use during charging.
Many users report crackling sound, a microphone that no longer picks up, or speakers that have become almost mute. These failures account for about 10% of recorded repairs.
The reasons are multiple:
Before considering a replacement, it is advisable to test with a wired headset or a Bluetooth kit. If the sound is correct with these accessories, the failure is indeed hardware. A thorough cleaning can sometimes suffice, but most of the time a component change is necessary.
Another frequent complaint concerns connectivity: unstable WiFi, Bluetooth disconnecting, mobile network dropping. According to a survey conducted by Android Authority in 2024, nearly 17% of Redmi users have already encountered persistent connection issues.
The origins vary:
A network settings reset often solves the problem. But if disconnections persist, replacing the internal antenna or WiFi module can cost 25 to 70 euros.
Photo quality is one of Redmi’s marketing arguments. Yet, many users encounter issues related to the camera sensor. The most frequent are:
The main causes are a damaged lens after a drop, a defective sensor, or a software bug related to an update. Cleaning the lens or testing with another photo app can help isolate the cause. In case of hardware failure, the repair costs between 30 and 80 euros.
A Redmi that reboots in a loop, freezes, or becomes very slow is a recurring problem, especially after several years of use. This type of failure is often linked to:
A factory reset sometimes resolves these issues. However, if the reboot loop persists, it may indicate a motherboard failure, much more costly to repair.
Not all problems require a trip to the workshop. Here are some useful clues:
Home repairs are possible for battery replacement or speaker cleaning. However, as soon as you need to open the motherboard or handle screen cables, it’s better to avoid improvisation.
Prices vary depending on the model, but here is a common estimate for an out-of-warranty Redmi:
These amounts explain why many users prefer to buy a new model rather than repair a device over two years old.
