Why Poco X5 5G Won't Turn On After Long Period of Inactivity

Poco X5 5G Not Turning On After Long Inactivity and Vibrating When Connected to Charging

A Poco X5 5G that won’t turn on after prolonged inactivity and vibrates when connected to charging has likely encountered a deep battery discharge issue or software failure. This condition often occurs when a device is stored without power for several months, causing the battery to lose its ability to accept charge properly.

Main Causes of the Problem

Deep battery discharge over 6-7 months without use is the most likely cause of the current situation. When a phone is stored without power, the lithium-ion battery gradually loses charge, and when it reaches a critically low level, it can enter a so-called “sleep mode” where the device stops recognizing charging.

Important: A voltage of 3.87V may seem within normal range, but this doesn’t guarantee that the battery is capable of accepting charge. After deep discharge, the battery’s internal resistance increases, which interferes with the normal charging process.

Other possible causes include:

• Software failures: Errors in the Android system that occurred during the last shutdown
• Contact issues: Oxidation of battery contacts or charging port
• Hardware failures: Damage to the power controller or other components

Fault Diagnosis

Before attempting to recover the device, it’s recommended to perform basic diagnostics:

1. Check charging equipment:

   • Use original or certified charging equipment
   • Try a different cable and adapter
   • Ensure the charger works properly with other devices

2. Assess battery condition:

   • A voltage of 3.87V indicates partial charge but insufficient for startup
   • If voltage is below 3.0V, the battery may be irreparably damaged

3. Observe device behavior:

   • Vibrating every 5 seconds when connected to charging usually indicates the system is attempting to wake up
   • No response to long press of the power button indicates a deep failure

Device Recovery Methods

Slow Charging for Battery Recovery

According to user and specialist recommendations, an effective recovery method is prolonged charging:

1. Leave the phone on charge for at least 24 hours without interruption
2. Disconnect from charging for 10-12 hours to allow the battery to “rest”
3. Connect with slow charging (use an adapter with lower power, such as 5W)
4. Wait for the battery icon to appear on the screen - this may take several hours

Important: Don’t interrupt the charging process in the first hours, even if it seems like nothing is happening. Deeply discharged batteries require time to “wake up.”

Recovery via Recovery Mode

If the slow charging method doesn’t work, try recovery via Recovery mode:

1. Charge the phone for at least 30 minutes using the method described above
2. Press and hold the “Volume +” and “Power” buttons simultaneously
3. Wait for the Xiaomi/Poco logo to appear
4. Use volume buttons to navigate and select “Wipe cache partition”
5. Reboot the device

Full Factory Reset

If previous methods don’t work, a full reset may be necessary:

1. Enter Recovery mode (as described above)
2. Select “Factory reset” or “Wipe data/factory reset”
3. Confirm the reset
4. Reboot the device

Warning: This method will delete all data from the device. If possible, try to recover data via Recovery mode first.

Using Specialized Tools

In complex cases, you may need to use:

• Xiaomi Mi Flash tools for system reflashing
• EDL (Emergency Download Mode) for deep flashing
• Specialized services for recovering deeply discharged devices

Preventive Measures

To avoid similar problems in the future:

1. Store the phone with 40-60% charge, not fully charged or discharged
2. Use original accessories for charging
3. Use the device regularly, even if briefly
4. Update system software to fix known bugs
5. Monitor battery condition and replace it at the first signs of degradation

When to Contact Service

Contact an authorized service center in the following cases:

• If all recovery methods haven’t helped within 48 hours
• If the battery is visibly swollen or has damage
• If additional problems occur during recovery attempts
• If the phone is under warranty

The service center can perform professional diagnostics, replace the battery if necessary, and restore the device to working condition.

Conclusion

The issue with a Poco X5 5G not turning on after prolonged storage is solvable in most cases. The main recovery methods include prolonged slow charging, recovery via Recovery mode, and full factory reset. It’s important to be patient and give the battery enough time to wake up. Preventive measures, such as storing the device with an optimal charge level, will help avoid similar problems in the future.
