Understanding and Resolving Samsung Slow Charging Issue

Understanding and Resolving Samsung Slow Charging Issue

Are you tired of waiting for hours for your Samsung device to charge? You're not alone. Slow charging is a common issue that many users face, causing frustration and disrupting their daily routine. But don't worry, this article has got you covered. We'll walk you through everything you need to know about Samsung slow charging, from understanding the problem to diagnosing and fixing it. Plus, we'll share some simple tips to prevent slow charging in the future. So, sit back, relax, and let's get your Samsung charging at lightning speed!

What is a Slow Charging? 

Slow charging occurs when a device takes significantly longer to recharge its battery than standard or fast charging speeds. This can result from various factors, including the use of incompatible chargers, outdated software, poor battery health, or the presence of active background applications that consume power even during charging. Slow charging can not only be frustrating due to the extended time required to reach full battery capacity but can also indicate underlying issues with the device's charging system or battery health that may need addressing.

Diagnosing Samsung Slow Charging Issues

If you suspect that your Samsung phone charging slow, here are some tips to diagnose the issue:

1. Using Samsung's Built-in Diagnostic Tools

Samsung devices come equipped with a set of hardware and software diagnostic tools designed to help users identify issues with their devices, including slow charging. Accessible through the Samsung Members app or the phone's dialer (by typing specific codes), these tools can check the battery's health, its charging capabilities, and whether the USB port is functioning correctly. By running these diagnostics, users can discern if the slow charging is a result of hardware failures, such as a degraded battery or a faulty charging port, which may require professional repair or replacement.

2. Third-party Applications

For a more in-depth analysis, third-party applications available on the Google Play Store can be used to diagnose slow charging problems. Apps like Ampere and Accu​Battery provide detailed insights into the charging process, including the charging speed (in mA), battery health, and estimated charging time. By monitoring these parameters over time, users can identify patterns or changes in charging behavior, potentially pinpointing the cause of slow charging. It's crucial, however, to choose reputable third-party applications with positive reviews and feedback, as some apps may inaccurately diagnose issues or even worsen the problem by consuming excessive battery power during testing.

How to fix Samsung Slow Charging

Here's how you can troubleshoot and solve the slow charging problem on your Samsung device.

Method 1. Updating Phone Software

Samsung frequently releases updates that can enhance device performance and fix bugs, including those that might affect charging speed. To update your phone software, navigate to Settings > Software update > Download and install. This ensures your device operates with the latest optimizations and security patches. An outdated system can often lead to compatibility issues with newer charging technologies, thus updating can sometimes instantly resolve slow charging issues.

Method 2. Changing Charger and Cable

Using an incompatible or faulty charger and cable is a common cause of slow charging. It's crucial to use only Samsung-approved chargers and cables that match your device's specifications. Over time, chargers and cables can wear out or get damaged, leading to decreased efficiency. Try using a different charger and cable, preferably one that's certified by Samsung. Also, check for reputable third-party brands like Anker that offer high-quality chargers for Samsung to see if the charging speed improves. This can often rectify the problem if the hardware is at fault.

Method 3. Optimizing Battery Usage

High battery usage by apps can sometimes make it seem like your phone is charging slowly because it's using power almost as quickly as it's being charged. To optimize battery usage, go to Settings > Device care > Battery, and adjust settings like power saving mode, background usage limits for specific apps, and adaptive battery. This not only helps in extending your battery life but can also ameliorate charging speeds by reducing the power draw during charging.

Preventive Measures to Avoid Slow Charging

Prevention is better than cure. To avoid encountering slow charging issues on your Samsung device, here are some preventive measures you can take.

1. Regular Software Updates

Keeping your phone up to date is not merely a corrective measure for slow charging but a preventive one as well. Regular software updates improve your phone's overall health and ensure compatibility with charging standards. It's important to regularly check for available software updates and promptly install them. This keeps your phone running smoothly and can prevent a multitude of issues, including slow charging.

2. Proper Battery and Charger Care

Taking good care of your battery and charger can significantly impact their performance and longevity. Avoid leaving your smartphone plugged in for long periods after it is fully charged. Also, try not to completely drain the battery before recharging it. Using and storing the charger and cable properly can also prevent physical damage that leads to inefficiency. Ensuring clean and dust-free charging ports on both your device and charger can also maintain an optimal connection.

3. App Management

Apps running in the background can extremely consume a huge amount of power, contributing to slower charging. Regularly monitoring and managing apps can help mitigate this issue. Uninstall unused apps and restrict unnecessary background activity for power-hungry apps via your phone's settings. Also, consider using apps designed to monitor and optimize battery usage. Proper app management not only helps in faster charging but can significantly improve overall device performance and battery health.


To wrap it up, Samsung device users can now confidently bid farewell to the frustrating issue of slow charging. With the help of the recommended diagnostic techniques and solutions, we can now keep our devices running at top speed, providing quick and effective energy restoration for everyone's fast-paced digital lives. These preventative measures and helpful tips empower consumers to stay connected without any interruptions caused by Samsung slow charging.


Here are some commonly asked questions about the Samsung slow charging.

Q1. Why does my Samsung phone charge so slowly?

Your Samsung phone might be charging slowly due to many reasons, such as using a charger with an incorrect voltage or amperage, a faulty charging cable, an overwhelmed power source, or background apps consuming power. It might also be due to the condition of the phone's battery, which can degrade over time and affect charging speed.

Q2. How can I make my Samsung charge faster?

To speed up charging on your Samsung phone, use the original charger & cable provided with the device, or ensure that any third-party chargers and cables are compatible and of good quality. Also, turn off the phone or put it in Airplane Mode while charging to reduce power usage, and avoid charging from a laptop or computer USB port as these often provide less power.

Q3. Is slow charging bad for your phone?

If slow charging is due to an aging or defective battery or a faulty charging setup, it could be a sign of a problem that needs addressing to avoid potential damage or degraded performance.
