When the fast charging not working It is normal for us to feel stressed. Because we are used to filling our phone's battery quickly, in just a few minutes, and now we cannot conceive that this could be any other way, although until a few years ago it took several hours to have the phone charged to 100%.
The fact is that, if your cell phone does not charge as fast as always, this means that there is a problem that may be more or less serious. Let's see what could be happening.
Causes why fast charging does not work
Although when this happens to us the first thing we do is check the mobile phone, the truth is that the problem is often not in this device, but in the cables and adapters.
If the battery charges, but does not charge at the usual rate, start by checking these parameters:
Cable
Not all USB cables can support fast charging, low quality ones cannot handle the high currents necessary and, therefore, when we use them the Battery recharging process is slower than usual.
The solution is to always use good quality cables and, if possible, the original ones supplied by the manufacturer of your mobile phone. If you need to buy a new one, Make sure it is suitable for fast charging.
Another option is that the cable we are using has suffered some damage. It is possible that you can see a nick or cut with the naked eye, but it is also possible that the damage has occurred internally and does not show any visible signs. This type of damage affects the cable's ability to transmit current. efficiently, so loading will be slow.
To find out if the damage is in the cable, try changing it for another one, or using that same cable to charge another mobile phone. If you detect that there may be a fault, do not put the cable back in the drawer, take it to the clean point for recycling.
Charging adapter
It is possible that the cable is fine and that what is causing the failure is the charging adapter. The same thing happens with these devices as with the USB cable, that not all of them are They adjust to the fast charging technology that your mobile phone uses.
It may also happen that the adapter has a lower output power than required, in which case it is not capable of providing the energy needed for fast charging.
As in the previous case, we recommend that you always use the original adapter for your mobile phone or, at least, one that is compatible with the fast charging technology that your device has.
Dirt or damage to the charging port
When fast charging doesn't work and it doesn't seem like the charging cable or adapter is to blame, the next thing you need to check is the charging port.
It is possible that this has an obstruction generated by the accumulation of dust, lint and dirt, which prevents the cable from connecting properly.
If you have a BB gun handy, you can clean it carefully. But you can also do this with a small non-metallic object, such as a toothpick, making sure you don't damage the connectors. Work carefully because this area of the mobile is very delicate.
Another explanation for the failure you are experiencing is that the charging port has been damaged. Perhaps it has worn out over time and frequent use and no longer allows a good connection; either Maybe the pins inside the port are bent or have been damaged as a result of a knock or by forcing the entry of a cable.
If the port is damaged, this is not excessively serious, since you can repair or replace it at an authorized technical service.
Device settings
It's time to start checking what's going on inside the phone, to see if it's having an effect on the battery charging speed.
- Battery configuration. Through the device settings, check the charging options section, since in some models it is possible to deactivate fast charging. Make sure you don't have this option turned off.
- Updating the operating system. When fast charging does not work, the cause may be an operating system update. Update it to the latest available version and, if the error persists, check to see if a corrective patch is available.
Device overheating
For safety, the fast charging system is automatically deactivated if it detects that the device is overheating. If you think this is what has happened, Disconnect your mobile from the electrical network and let it cool down.
Battery problems if fast charging does not work
Of course, the problem may be with the battery itself. These devices have a limited life cycle, and yours may be too worn out and no longer supports fast charging.
If your battery is not old enough to be able to blame this problem on wear, it may have a factory defect, for example. It is advisable that you contact the technical service.
Interference caused by a third-party application
Some of the apps that we install on our mobile have the ability to interfere with the fast charging process, because they try to manage battery or device power usage. We are not aware of it because we never read the terms and conditions of the applications nor do we usually review what we are giving them access to.
If the problem is caused by this, solving it is as simple as disabling or uninstalling third-party apps that can manage the battery. The complicated thing is know which exactly are the applications that can do this.
When fast charging does not work, the fault may be in the hardware or the software, and we have to do different tests until we find what exactly is not working well. If you have reviewed everything we have mentioned and the system still does not work, It is best that you contact the manufacturer's technical support.
