Smartphone is Charging Too Slow | How to Fix it?

Smartphones are an essential part of everyone’s everyday life. And we all know the importance of the battery life of our phones. We’ve all been there: glued to our phones, desperately waiting for that precious charge symbol to tick upwards. But sometimes, even patience wears thin when your smartphone charges slower than a sloth on vacation.

In this article, we will explore the 7 reasons why your smartphone is charging too slow and how to fix the issue tp get the most out of your device’s battery life.

7 Reasons Why Your Smartphone Is Charging Too Slowly

Now that you know how battery charging works, it’s time to look at what might slow down your older phone while charging. Most likely, it’s because of one of the following reasons:

1. The Faulty Charging Cable

One of the most common reasons why smartphones charge too slow is using faulty chargers. There can be some internal issues or sometimes there could be minor break in the charging cable which may not be easily visible from eyes.

Also, using unbranded or from different brand chargers than the smartphone itself can also lead to charging the smartphone slowly. Before coming out to the conclusion, always try charging your smartphone from multiple chargers.

2. The Power Struggle: Weak Chargers and Power Sources

Not all chargers are created equal. A low-powered adapter, like the one you might use for a lamp, simply won’t deliver the juice your phone craves. Similarly, plugging your phone into a USB port on your computer might lead to a slower charge compared to a wall outlet.

The Fix: Use the charger that came with your phone, or one that supports the same wattage. When in doubt, consult your phone’s manual for specific recommendations. Opt for wall outlets over USB ports for faster charging.

3. Background Apps

Phones that take forever to charge can also have difficulty keeping a charge when in use. A rogue app, or background apps in general, could be the reason for this.

Android and iOS now have tools to find out what apps are running in the background. Check out the battery usage menu at Settings > Battery for Android-based devices. On your iPhone, select Battery in the Settings app to see which apps use the most battery.

When you think you’ve located the malicious app, delete it and see if your battery life and charging speed improve.

4. Aging Battery

If you’ve exhausted the other tips on this list and the battery still seems to take forever to charge, you might think about having the battery replaced.

The little industry secret is that lithium-ion batteries don’t last forever and can only be recharged a limited number of times. Therefore, it could be that the battery is causing the slow recharging. Take your phone to an authorised dealer for more information on replacing the battery in your device.

5. Outdated Operating Systems Can Make Charging Slow

Just like a buggy car, outdated software can lead to unexpected issues, including slow charging. Operating system updates frequently address bugs that can impact a device’s performance and power management capabilities. An unresolved bug in an older OS version could lead to poor battery performance and slow charging.

The Fix: Make sure your phone’s operating system is up-to-date. Software updates often include bug fixes and performance improvements that can optimise charging efficiency.

6. Wireless Charging: Convenience at a Cost

Wireless charging offers undeniable convenience, but it’s generally slower than wired charging due to energy loss during the transfer.

The Fix: If speed is your priority, stick to wired charging. However, if convenience reigns supreme, wireless charging is still a viable option, just be prepared for a slightly longer wait.

7. Fast Charger That Your Smartphone May Not Support

Fast charging is a beautiful thing, but it’s important to understand that not all phones or chargers support it. Additionally, some fast charging technologies require specific cable and adapter combinations to work.

The Fix: Consult your phone’s manual or manufacturer’s website to see if your phone supports fast charging and what type of cable and adapter you need. Invest in fast-charging compatible accessories for a significant speed boost.


By following these tips, you should be well-equipped to diagnose the cause of your phone’s sluggish charging and get it back to juicing up at lightning speed. Remember, a little detective work can save you a lot of waiting time and frustration. So, the next time your phone seems stuck on a charging crawl, don’t despair! With a bit of troubleshooting know-how, you’ll be back to conquering your digital world in no time. Happy charging!
