Comparing it to charging a battery from a few years before it's a huge technological leap.  During the usage of the device, many components simply wear out and do not work as well as in the beginning. Do you know the situation, when you plug in your phone and after long hours it received only a few extra percent? Do you feel like it takes ages to fully recharge your device? Or maybe the battery stays on the same level, regardless you've plugged it in? In this article, we've gathered some ideas, which may be a possible reason for this slow charging. What's more, we give you some solutions to this issue.

Why is your battery charging so slowly and how to fix it?

1. Damaged Cable.

It is one of the most probable reasons why your phone is charging so slowly (or actually do not charge at all) -  it's natural for charging cables to damage. We use them every day, pull them, and actually do not care about them at all. Do you remember the situation you've rolled it very tightly? Or you just threw it to the bag, slammed it with some heavy objects, and after that tried to take it out by pulling it rapidly? All these small situations contributed to more and more injuries of USB cable - ripping inside components or tipping ends of the cable. The only way to fix this problem is to replace the cable - it's not expensive and it can be a deal-breaker.


2. Adapter problem.

This is another very common problem why your phone is charging so slowly (or actually do not charge at all). We use these small blocks very often, so it's natural for them to wear out. You may not even notice small damages, like f.ex. loose slot for a cable or some inside issues which you cannot see. Because they are still exposed to electricity and changes in their intensity, they are not the most lasting items in the world. What you can do? Let's replace the old adapter with a new one. This operation should help with coming back to fast charging.

3. Used Battery.

Slow charging issues may be caused by... a producer. Sometimes the developers make mistakes and allow for sale phones with defective batteries. Fortunately, there is good news - you can check your phone online if it's from the faulty batch. In case it is you should contact your provider for a replacement. Remember, it will work in case you've bought your phone and from the very beginning you've had battery problems. Just like the smartphone, the battery in it also gets older and becomes not as efficient as it was. what's more, replacing the battery nowadays is difficult. Almost all smartphones are non-openable, which provides waterproofness but also prevents from opening it and replacing the battery by the user. The only solution - send it to a shop or a provider to replace it.

4.  Old Phone.

Your phone may be old in two ways - it depends on approaching this subject. There is nothing wrong with old phones, but remember that devices have changed a lot. Starting from the size of the screen, its abilities, ending with the system and processors. And this is exactly what can 'cause' the slow charging. Nowaday's processors support fast charging, and these which are present in older models do not. So if you're comparing the time your battery needs to be full with people, who have newer smartphones (and what's connected they also have support for charging), then let's stop and consider buying a new phone.

On the other hand, if you're sure that your phone gained power much faster than it does now, then, unfortunately, your phone is not getting younger. All components may be damaged by consumption and they do not have the ability to recover. What can you do in this situation? The steps are simply the same as in a previous way - consider replacing your device for a newer model.

5. Too modern charging?

On the other hand, if your phone isn't old for sure, the type of charging itself may be a problem. Nowadays we've got few possibilities to charge our devices, starting with the usual type using the cable and adapter, through charging it using PC and ending with wireless charging. We do not say that the last two types of charging aren't successful - you'll surely recharge your phone. Unfortunately using PC as a charger is the slowest option of recharging. What's more, if the USB cable you're using is even a little damaged it will cause slower charging than normally. And what about wireless charging? It's an awesome idea, a cool solution, and confirmation of nowadays technology but... It's not as fast as a regular type of charging. So what's the conclusion? If you like to show off, use the wireless option, but if you want to recharge your phone fastly - simply plug it in.

6. Problematic USB port.

Unfortunately, this little slot that you use to recharge your device may cause many, many problems. There can be a few reasons why your device charges so slowly:

Let's be honest, how many times do you throw your device into a pocket or a bag without even thinking about the dust or small balls of dirt? That small hole in your device very willingly collects all those items and after the time it naturally will get clogged. What's more, if you plug in your device without notifying the dirt, you simply push it deeper what can cause the connection problems and then issues with charging. What can you do in this case? Let's inspect the USB port and if you see anything strange, which certainly shouldn't be there, just act like a surgery doctor. Take a thin object, which can fit in the port and remove the dust. Remember to be very careful (like a mentioned surgeon) - you don't want to cause more damages and end up with a total disaster.

Corrosion is another problem that may be responsible for slowly charging. Corrosion? Inside a smartphone? Yes, it sounds strange, but unfortunately, water can get into this little slot. This damage creates a shell/coat on components that are responsible for charging and limits it visibly or stops it at all. And what's worse - it will eat your device from inside if you won't stop it. What can you do in this case? Well, take your phone to a specialist and let him do his job. If you're the DIY person, then you can try to remove it by yourself - you'll need white vinegar and rubbing alcohol. Disassemble your device, rub the corrosion with a cotton dipped in white vinegar but be very careful and don't put it on not corroded parts. Leave it for a few minutes (5 or so) then dry the area with a tip of paper towel. Repeat the whole step until you'll not notice any corrosion. Then let's use a cotton dipped in rubbing alcohol, wipe cleared area with it and let it naturally dry for a half-hour. After this process, your device should be okay, and charging should look like nothing happened. Remember, if you do not feel okay with an opening smartphone and you've got no experience, then it's better to rely on specialist work.

Well, to be honest, that situation is the worst. If nothing helps your battery to charge faster, then it may be the main problem. This situation unfortunately doesn't give you many opportunities - all you can do is take your device into a professional. 

7. Opened apps.

We are sure you know that situation - you're using one app, then you have to do something immediately in another one, so you leave the first one open and usually forget about it. And that's the possible reason not only for slow charging but also a faster loss of battery percentage. If you've noticed both, then it's highly possible, that background apps are responsible for slow charging. Remember to clean the background from time to time to save the battery and charge it a little faster. What's more, it could be only one app, which stills works in the background and you even don't know about it because it boots itself. What you can do to reduce this problem? Try the task manager and localize the misbehaving app and try to uninstall it. 

8. You in your own person. 

Let's think, how many times you've checked your social media and how much time you've spent on it? Do you like playing games and you forget about the whole world while playing? Do you use your smartphone while it's charging? That's it! The screen eats the biggest amount of battery, so naturally, if you're using your device and charge it at the same time it literally is a vicious circle. Device gains more percents while charging, but at the same time, it loses it because you're doing something that consumes the battery. The combination of this problem and some presented above for sure will cause slow battery charging. What is the solution? Leave your device in rest and let it gain power.
