Why is My Cell Phone Charging So Slowly?

why my Cell Phone Charging slowly?

You wake up in the morning, ready for a long day in office. But your charge is still 60%? After being plugged in all night? Don’t worry. You are not the only one facing this problem. The truth is, after some time, this problem affects almost every smartphone, and usually for the same reasons. Here, we have listed some of the most common reasons why your cell phone is charging so slowly, and what you can do to fix it. 

  1. USB cables

More often than not, the first offender, in any case of slow charging, is always your USB cable. They usually get bent, twisted, battered, coiled, and just generally abused. The ends get full of fluff. And at times, the USB connector also gets worn and becomes loose when your phone is plugged in. Can we expect them to provide fast charging after all this? At this juncture, try replacing your cable and see if it was the real culprit. Always, and I cannot stress this enough, buy cables from reliable brands that have a high gauge and are compatible with your charging adapter’s output ratings. And if your phone supports fast charging, make sure your new cable supports that particular charging protocol.

Suppose you charge your phone through your computer(laptop or desktop). In this case, you will undoubtedly get a pretty glacial charge compared to a wall outlet. You might own the latest USB(the 3.0 versions), but the standard energy output of a PC is a meagre 0.9A( 1.5A if no data sync is on). And god help you if you are still using a USB 2.0, in which case it’s even lower at 0.5mA. And that that’s under ideal circumstances! If your USB or port is damaged, you are going to get a still slower charge. So the next time you want to charge your phone, plug it into the wall like good old times!

By the same token, if you are using wireless charging (or even reverse wireless charging), you will get a sluggish charge. Wireless charging is cool and all, but we’re fighting against physics and safety here. Qi is a brilliant technology, but if time is of the essence, sorry to say, this isn’t for you!

  1. Port issues

Your phone’s charging port also suffers some significant damage over time. Look at the port for corrosion or obstruction. A clogged port can significantly lower your phone’s charging speed. However, thankfully, there’s a low-tech fix for it! You can use a plastic toothpick or a small, soft brush to remove obstructions like lint, dust, etc. But be very careful while doing this; otherwise, you might end up damaging the port’s components. And if your clog is of the more severe variety, try using a compressed air can to blow out the excessive build-up.

  1. Faulty adapter

USB cable and port in perfect condition? And yet, your phone is charging slowly? In this case, it’s probably your adapter that’s causing the mayhem. Yes, that little blocky thing! It’s always best to use the adapter that came with your phone. Or, at least, replace it with another adapter of the same type.

Moreover, adapters are not the most sturdy of devices. Who knows, maybe it got kicked around during a move, or a power surge left it a bit skewed. Anyway, grab a new adaptor and get back to charging lightning-speed!

  1. Using phone while charging

Do you use your phone even when it’s charging? Then, you are the reason why your phone takes so long to charge. Using the phone while charging wastes a significant amount of battery on keeping the phone up and going. And this parallel power consumption decreases the overall charging speed. 

Besides, many phones heat up if they are used while charging. And when the heat crosses a particular level, your phone starts throttling the charging speed and performance to maintain a stable temperature. Not only that, the excess heat from the processor and display can also damage your battery or severely reduce its cycle life. 

So, all in all, it is always in your interest to NOT use your phone while charging. Just turn off all connectivity features like Bluetooth, WiFi, mobile data, put it into the airplane mode, or, better yet, turn it off entirely before putting it to charge.

  1. Old batteries

With time, lithium-ion batteries lose their efficiency. However, it can also happen due to unhealthy charging practices. So, if your phone is not charging as fast as it used to, get it checked at the brand authorized service centre and ask for a battery replacement.

If your phone is within the warranty period, the battery will be replaced for free. And even for out of warranty cases, the replacement costs aren’t sky-high. That being said, don’t go for local batteries in any event!

  1. Old cell phone

We know it’s a touchy subject, but it might be high time to upgrade your phone. An older phone means an older battery, something which gets increasingly slower with every passing day. So now, you own a phone that you know used to charge faster but doesn’t do the trick anymore. On the other hand, modern smartphones are equipped with processors that support fast-charging technology to take you from 0 to 50% in just 15 minutes. Moreover, some phones even have turbocharging capabilities. 

The sad truth is, things fall apart, and we must learn to let go. So if your phone is at least 3+ years old, it’s only fitting that you consider buying a new phone.

  1. Background apps

If your phone takes forever to charge, you must get rid of background apps immediately. Both Android and iOS have tools to help you find out the background apps. For Android phones, check out the battery usage menu located at Settings > Battery (it can also be under a section like Device care). And if you own an iPhone, select Battery in the Settings app to see which apps are using the most of your battery. However, some apps might show high battery usage just because you use them frequently. So, don’t be tricked! Also, look for apps that you use rarely but have maximum battery consumption. DELETE those malicious apps! You will notice a dramatic increase in your battery life and charging speed.


Here, we discussed some of the most commonplace reasons for slow charging. So, detect what exactly is bothering your phone, fix it and get back to fast charging!
