Have you ever found yourself in the distressing situation of not knowing how to recover your phone's internal memory when it won't turn on? If your device has been hit, exposed to moisture, has had battery issues, or simply stopped responding unexpectedly, you're probably worried about the potential loss of your photos, videos, contacts, and other important files.

In this definitive guide we explain to you All possible causes of failure, the most complete and effective methods to recover data from the internal memory of a mobile phone that won't turn on and everything you need to know, whether you are a private user or need information to manage data of professional or legal importance.

Main reasons why a mobile phone does not turn on

Deteriorated or exhausted battery: When the battery has reached the end of its useful life or suffers from occasional failures, the device may not turn on even if the rest of the hardware is in good condition.
Physical damage from falls or blows: A broken motherboard, internal connectors, or even components like the power button can render your phone completely inoperable.
Software problems or corrupted operating system: The phone may stay on a black screen, restart in a loop, or not respond due to firmware or system errors.
Humidity, water or exposure to liquids: Short circuits and moisture damage affect circuits and memory, preventing the equipment from starting.
Accumulation of dirt, dust or carbon on connectors: prevents proper charging and causes the phone to become unresponsive when trying to turn it on.
Broken or damaged power button: If the mechanical button is damaged, the device will not be able to boot even if the rest of the components are working properly.
Overheating, viruses, malware, or system failures: can cause critical crashes and damage to operating system boot.

It's fundamental identify the cause before attempting any recovery option, as the most appropriate method and the actual chances of success will depend on it.

Is it the screen or the phone? Check the problem before acting.

Before creating an unnecessary alert or jumping into complicated procedures, the first thing is rule out that the fault is only with the screenMany seemingly dead phones are still on, but with a broken, black, or disconnected screen.

To check:

Connect your phone to your computer using the original USB cable.If you've previously enabled file transfer without asking for permission, your computer should recognize the device.
Access the mobile as a storage unit and copy important files to a folder on your PC or Mac.
If your device asks for on-screen permission to access data, but you can't accept it because the screen is unusable, this method won't work, but you may want to consider using an OTG cable and a USB mouse to simulate tapping on the screen.

Expert advice: If the problem is only with the screen, recovery is almost immediate using a computer. If the device is unresponsive or the PC doesn't detect it, you'll need to move on to more advanced recovery methods.
