Why my phone is slowly charging

Why your phone isn't charging fast can be this problem:

■Your phone is hot, which can be slowly your charge

■Can be your cable or your charge? Don't support fast charging

Those my are my problem as well

fast charging requires a proper data cable and an adapter that can fast charge.

If both are verified on another phone, you have a phone problem.

Why my phone is slow charging

A charging time of twelve hours to get to 100% on your realme C21Y is extremely slow and is definitely not normal. The phone comes with a 5000mAh battery and is shipped with a 10W charger, which should typically take around 3 to 4 hours for a full charge from zero.¹ A 12-hour charge time indicates a significant problem.

Here's a breakdown of the most likely reasons and what you can do about it:

1. Faulty or Damaged Charger/Cable: This is the most common culprit. The cable or the adapter itself could be damaged, even if there's no visible sign of wear and tear.² A low-quality or non-original charger might not be able to deliver the full 10W of power, severely slowing down the charging process.

#

1. Dirty or Damaged Charging Port: Over time, dust, lint, and other debris can accumulate in the micro-USB charging port of your phone. This can obstruct the connection and prevent the charger from making proper contact, resulting in a trickle charge. A physically damaged port, with bent pins, would also cause a similar issue.
2. Aging or Degraded Battery: While the realme C21Y is a relatively newer model, if your phone has gone through a lot of charge cycles or has been exposed to extreme heat, the battery's health may have degraded. As batteries age, they become less efficient at accepting and holding a charge.³

#

1. Software Glitch or Update Bug: A recent software update could have introduced a bug that affects the phone's power management.⁴ This is a possibility, and some users in the realme community have reported a decrease in charging speed after an update.

#

1. Using the Phone While Charging: If you are using your phone for resource-intensive tasks like gaming or video streaming while it's plugged in, the power being drawn by the phone can be equal to or greater than the power it's receiving, leading to extremely slow charging or no charging at all.⁵ This also generates a lot of heat, which can further slow down the process as a safety measure.

Here’s what you should do to troubleshoot and fix the problem, starting with the simplest solutions:

Step 1: Check Your Charging Equipment

• Try a different charger: The easiest way to rule out a faulty charger is to try a different one. Use another 10W or higher-wattage charger (preferably a realme original) and cable. If the phone charges normally, the original charger or cable is the problem.
• Inspect the cable: Look for any frays, bends, or other visible damage on the charging cable.
• Check the adapter: Make sure the adapter isn't getting unusually hot.

Step 2: Clean the Charging Port

• Power off your phone.
• Using a toothpick, a small soft brush, or a can of compressed air, gently clean out any dust or lint from the micro-USB port.⁶ Be very careful not to damage the delicate pins inside.

Step 3: Optimize Your Phone While Charging

• Charge with the screen off: The display is a major power consumer.⁷

*

• Don't use the phone: Avoid using the phone for any purpose while it is charging, especially for gaming or watching videos.⁸

*

• Close background apps: Close all unnecessary apps running in the background.⁹

*

• Enable Airplane Mode: For the fastest possible charge, put the phone in airplane mode to turn off Wi-Fi, mobile data, and Bluetooth.¹⁰

*

• Remove the case: If you are charging in a warm environment, remove the phone's case to allow for better heat dissipation. High temperatures can drastically slow down charging.¹¹

*

Step 4: Check for Software Issues

• Restart your phone: A simple restart can often fix temporary software glitches.
• Check for system updates: Go to Settings > Software Update to see if there's a new version of the OS available. An update might include bug fixes for power management.¹²

Step 5: Last Resort (Contact Support)

If you've tried all the steps above and the phone is still taking 12 hours to charge, the problem is likely a hardware issue with the battery or the charging circuit on the motherboard. In this case, you should:

• Contact realme Customer Service: Explain the troubleshooting steps you've already taken.¹³

*

• Visit a realme Service Center: Take your phone, the original charger, and the bill/proof of purchase to a service center for a professional diagnosis and repair.¹⁴ They will be able to test the battery and the charging port to find the exact problem.
