The Xiaomi Mi 5, released in 2016, is still popular with users due to its powerful hardware and affordable price. But even reliable technology breaks down: one of the most common problems is that the device stops turning on. The reasons can range from a trivial battery discharge to serious hardware breakdowns. In this article, we will examine all possible scenarios why the smartphone does not respond to the power button, and what to do about it, from simple actions to complex repairs.

• 🔊 No-image sounds – download signals are heard, but the screen remains black.

Each of these symptoms indicates different problems, such as if the Mi 5 vibrates when you connect the charger, but it doesn't turn on, it's probably the battery or the power controller, and if the phone is stuck on the logo, it could be a software failure or damage to the memory partition.

Also note the previous events:

• 💥 Did the phone fall before the breakdown?
• 🔌 Have there been problems with charging (slow charging, spontaneous shutdown)?
• 📱 Have you installed custom firmware or rooted the device?
• 🌡️ Did the smartphone work in conditions of high humidity or temperature changes?

2. Program reasons: when the software is to blame

If the Xiaomi Mi 5 reacts to the power button (vibrates, the screen lights up), but does not load beyond the logo - the problem is most likely in the software.
