Slow phone charging usually happens because of a weak charger, faulty cables, dirty charging ports, an ageing battery, or poor power sources. Sometimes there could be a single reason, sometimes there’s more than one. Whatever the reason is, fixing it early can solve this issue and restore the phone’s overall performance.
With a few changes you can get your phone charging speed back to normal. Research shows that almost 40% causes of slow charging is due to dirty port or low quality, faulty cables. You don’t need to be a tech expert to solve this. With the right accessories and a few smart habits, you can make your phone charge faster and extend its battery life.
At Pacoli Power, we make this easier by offering durable fast chargers, reliable charging cables, and trusted mobile accessories that keep your devices powered up quickly and safely.
Common Reasons for Slow Phone Charging
Slow charging is one of the most common charging issues people face. The good news? It usually comes down to a few simple causes that are easy to check.
1. Your Charger Isn’t Giving Enough Power
The little adapter you plug into the wall matters a lot. Old or low-power chargers just don’t have the juice your phone needs for fast charging. For example, a phone that supports 20W or higher will crawl if you’re using a basic 5W phone charger.
2. The Charging Cable Isn’t Doing Its Job
A worn-out or low-quality charging cable is another big reason for slow charging. Frayed cords, cheap knockoffs, or extra-long cables can all limit the power flow. If your phone is charging slowly, the easiest fix is often just swapping in a certified cable.
3. Something’s Stuck in the Charging Port
Your charging port is a magnet for lint, dust, and dirt. Even a small blockage can mess with the connection between your phone and the charger, slowing the charging process or causing the phone to keep disconnecting. A gentle blast of compressed air or careful cleaning can get things back to normal.
4. Your Battery’s Getting Old
Over time, every phone battery loses some of its ability to hold a charge. An older battery won’t charge as quickly as it used to, no matter how good your charger or cable is. If your phone is a few years old, slower charging might just be a sign of battery health decline.
5. You’re Using the Phone While Charging
Watching Netflix, scrolling through social media, or gaming while your phone is plugged in? That’s one of the easiest ways to slow down charging. When you use your phone while it’s charging, the battery is draining and charging at the same time, which drags out the whole charging process.
6. Heat Is Getting in the Way
Phones don’t like getting too hot. If your phone warms up while charging, whether from heavy use, a phone case that traps heat, or just being in a hot room, it will automatically slow charging to protect the battery. Cold weather can also affect charging speeds, making your phone charge more slowly.
7. The Power Source Is Too Weak
Not all power sources are equal. A USB port on a laptop or car charger often provides only a small trickle of power, making your phone charge slowly. Even a multi-port adapter can split power between devices, which means your phone gets less and takes longer to fill up.
Device-Specific Reasons for Slow Charging
For iPhone
- Using the old 5W brick instead of a 20W fast charger will always feel painfully slow.
- iOS sometimes pops up with a “Slow Charger” warning if your adapter doesn’t deliver enough power.
- Apple’s Optimised Battery Charging is designed to keep your battery healthy, but it intentionally slows charging at certain times (like overnight).
- Heat or a chunky phone case can also slow down your iPhone ease charging speed.
Samsung Galaxy
- Most Galaxy models expect 25W fast charging, while the higher-end ones go up to 45W Super Fast Charging. If your charger doesn’t match, your phone will take longer.
- Fast charging won’t even kick in unless you’ve enabled it in settings.
- A poor-quality USB-C cable can bottleneck the power, even with the right charger.
- Streaming, gaming, or multitasking while charging eats up power and stretches the charging time.
Google Pixel
- Google’s Adaptive Charging deliberately slows things down at night to help your battery last longer.
- If your phone isn’t perfectly placed on the wireless charger, or if you’re using a thick case, charging speed drops.
- Pixels don’t like getting hot. When they do, they’ll slow down or pause charging.
- Charging from a laptop or car USB port is usually a crawl, since those don’t push much power.
Other Charging Situations
- Laptop USB ports usually give just a trickle of power.
- Car chargers often don’t support real fast charging.
- Multi-port chargers split the power, so if you’re charging multiple devices, your phone gets less juice.
How to Check Why Your Phone Is Charging Slowly
If your phone is charging slowly, don’t rush to buy a new charger or blame your battery just yet. A few simple checks can save you time (and money). Here’s what to do:
Look at the adapter you’re using. Modern phones need a fast charger (20W or more for iPhones, 25W or 45W for Galaxy phones). If you’re still using an old or low-power plug, that’s why your charging speed feels so slow.
Your charging cable carries the power, so if it’s worn out, bent, or just poor quality, it can slow down the charging process. Swap it with a good, certified USB cable and see if your phone charges faster.
A dirty or dusty charging port can block the connection between your phone and cable. Use a bit of compressed air to clear it out. A clean port often makes a huge difference in charging efficiency.
Where you plug in matters. A USB port on a laptop or car gives very little power, which makes your phone charge slowly. Always test with a wall outlet and the proper adapter to get the best charging speed.
How to Fix a Slow Charging Phone
1. Use the Right Charger and Cable
Start with the basics. A weak adapter or a worn-out charging cable can easily cause slower charging speeds. Make sure you’re using a certified fast charger (20W or more for iPhones, 25W/45W for Samsung Galaxy, etc.) along with a proper USB-C or Lightning cable.
2. Clean the Charging Port
Your charging port collects lint and dust over time, and that can block the connection between your phone and charger. Use a bit of compressed air or a soft brush to gently clean it. A small step that often makes a big difference in charging efficiency.
3. Choose the Best Power Source
Not all power sources are equal. USB ports on laptops or cars usually deliver very little power, which is why your phone may charge slowly. For faster charging, always plug into a wall outlet with the proper fast charger.
4. Reduce Phone Use While Charging
If you’re using your phone while it’s charging, playing games, streaming, or even scrolling social media, the battery drains as it charges, slowing the whole charging process. To charge faster, let your phone rest until it reaches a decent level.
5. Check Battery Health and Settings
Finally, look at your phone’s battery health and software settings. iPhones have Optimized Battery Charging, Samsung devices require you to enable Fast Charging, and Pixels use Adaptive Charging. If your battery is old or degraded, no charger will help. You may need a replacement for truly efficient charging.
Myths About Phone Charging Speed
Myth 1: Draining Your Battery to Zero Is Good
Many people think you need to let your phone battery die completely to keep it healthy. This is not true. In fact, it can actually harm your battery over time. It’s better to charge your phone a little here and there instead of waiting until it’s totally empty.
Myth 2: You Can Only Use the Charger That Came with Your Phone
While it’s important to avoid extremely cheap, low-quality chargers, you don’t have to use only the one that came in the box. Chargers from well-known, reliable brands work perfectly well and are safe to use. Just make sure you choose a trusted product.
Myth 3: Overnight Charging Will Damage Your Battery
Some people believe that leaving your phone plugged in all night will overcharge the battery. But your phone is designed to stop charging once it’s full. It’s completely safe to charge overnight, and many phones even adjust charging to finish right before you wake up.
Best Practices for Maintaining Fast Charging and Battery Health
Nobody likes waiting forever for their phone to charge, right? The good news is, a few small habits can make your charging process quicker and protect your battery health at the same time. Start with your gear: always use a certified fast charger and a good charging cable. Cheap cords or weak adapters often lead to slower charging and even long-term charging issues.
Next, keep an eye on your charging port. Dust and lint build up easily, and that tiny blockage can slow everything down. A quick clean with compressed air usually does the trick. Also, try to avoid heat. Charging in direct sunlight or with a bulky phone case can make your phone charge slowly because the system reduces speed to protect the battery. Finally, stick to a proper wall outlet instead of a USB port on your laptop or car if you want faster charging.
FAQs
