What to do if the phone does not charge

Quick question and answer

Takes a long time to charge

The problem may be due to broken cable cores. Also, you should not buy cheap non-original charging cords, as fakes break even from the slightest bends.

In addition, you should pay attention to the additional load of the phone:

Games,
Watching videos (including YouTube),
Internet distribution via Wi-Fi to other devices is enabled,
Viruses (unreasonably increased consumption of traffic from the package).

Weak power supply - chargers with 0.3-0.5A are not suitable for modern smartphones. This problem is more relevant for portable chargers and external power banks. The current strength in a power bank does not exceed 1 ampere, while some batteries require a current of at least 1.5-2 A.

Stopped charging

You need to check the charger and cord
Inspect the connector. Perhaps it is clogged with dirt, dust, rust, which is why energy does not flow to the controller, and therefore to the battery.
Perhaps the battery has been “decided to live for a long time” (about this a little higher).

Discharges quickly

The reason may lie in phone viruses. It is important to regularly clean your devices of unknown files, and also download programs only from official sites. Due to viruses, the operating system begins to glitch. Usually a reset to factory settings helps; in extreme cases, the device needs to be taken in for flashing.

If the battery is more than 5 years old, this is probably the problem. Only replacing it with a new one will help here.

Shows charging but not charging

If the % charge remains in one place for a long time (from 15 to 30 minutes):

In rare cases, the problem is in the unit or cable. When some veins are broken, so there is not enough energy to start charging.
Check to see if the battery is swollen or leaking. You can try to restore capacity. To do this, you need to completely discharge the phone, then connect the charger to it and leave it for several hours longer than usual. Carry out 2-3 cycles. If the situation has not changed, buy a new battery.

Doesn't take charge after water

After a mobile phone falls into water, snow, toilet, soup, etc., the following may happen:

The battery failed due to a short circuit,
The system writes that moisture or condensation has been detected - immediately turn off the device and dry it for a couple of days,
The motherboard or power controller is flooded with water. In this case, we recommend contacting a service center, as self-repair may aggravate the situation.

Wireless charging problem

To improve the quality of wireless charging, it is recommended to remove the thick case, since some devices simply cannot “break through” silicone or plastic protection, especially if there are metal inserts. It would be a good idea to make sure that there are no foreign objects between the charger and the cover of the device.

Sometimes the problem may be that the wireless station did not recognize the smartphone. In this case, the indicator will blink, but the process will not start. To fix the problem, remove the phone from the station, wait 5-10 seconds and put it back down.

Also, before putting your cell phone to charge, be sure to disconnect data transfer via the USB cable from your computer or laptop.

REFERENCE! Make sure that the device lies exactly in the center of the station. Displacements are allowed within 1 cm, no more.

Magnetic cable

Usually the problem is that the current carried by the magnetic cable is less than 0.8 A. The optimal option for operation is 2A, and even better, all 3A.
The magnetic tip often gets clogged; clean it regularly.

Gets very hot

The normal operating temperature for batteries with high power (from 3000 to 6000 mAh) is up to 30-35 degrees. But if the charging percentage does not increase, you need to replace the battery.

Sometimes charging directly helps

REFERENCE! This option is not suitable for devices with a non-removable battery.

To use this method, you need to do the following:

Remove the battery.
Insert the battery into the frog so that the terminals are connected to the + and - contacts.
After this, plug the device into a power outlet. If the green light on it lights up, it means everything is connected correctly.
It will take approximately 2-3 hours to fill the battery.

How to prevent such a malfunction

It is enough to follow simple rules:

Use original and high-quality chargers and cables;
Do not use your phone or tablet while charging. Excessive movements may cause the connector to become loose. You can also try magnetic chargers and wires. They are easy to detach;
Do not charge the phone from the car network immediately after starting;
Do not discharge your smartphone to 0 and do not charge it to 100%. The ideal middle is from 10% to 90%. This is a proven fact. This way the battery will last much longer;
Protect your phone and its connectors from dirt, dust and moisture;
Try to prevent your phone from overheating or hypothermia outdoors and do not use it in such conditions. This negatively affects the condition of the battery and can reduce the service life of its serviceable operation and warranty.

Symptoms of failure

There are many technical reasons that affect the speed and performance of smartphone charging. There are several symptoms that indicate a problem with the battery or charging process of the mobile device:

The smartphone charges extremely slowly;
Charging does not occur at all.

The user has two options for repairing it - on his own or contacting a technical center and entrusting the repair to specialists. What to do if your phone is charging slowly - it is recommended to first diagnose your cell phone.

Recommendations

To ensure that your smartphone operates normally, including charging normally and holding charge well, we recommend that you follow the following tips.

Don't drop

Impacts, especially on a hard surface, in most cases lead to damage to phone parts, including the battery.

Don't charge too often

You cannot use the phone 24 hours a day.
You cannot drain the battery completely.
It is necessary to keep the battery level 20-80%.
Do not leave the charger connected overnight.

Observe the temperature regime

It is not recommended to leave any electronics in cold or extreme heat. Suitable operating temperature is +3-+45 degrees.

Use an antivirus program

This program will protect your phone from viruses and warn about dangerous sites and programs.

Do not use low-power chargers

Chargers with a power less than 0.5 A are not suitable for smartphones. The optimal level is 1-2 A.

How to restore the battery

The most common way is to supply current to the contacts from another power source (this could be a “frog” or another working charger).

REFERENCE! If the battery fails, the described measure will only be a temporary solution; in the future, you will still have to replace the battery.

How to clean the port hole in the phone

On mobile phones and tablets, the charging hole has a port. On which small fragile parts are placed. If they are violated, technical service will be required. And this is already additional waste. Therefore, you need to be careful when cleaning it. A toothpick is best for this.

Since metal objects can damage the port. The end of the toothpick can be sharpened so that it can better penetrate hard-to-reach places. And also dip its end in alcohol or solvent.

Before cleaning, it is better to turn off the device. Only after complete cleaning and removal of dirt and dust that has accumulated there can the phone be turned on again. Alcohol can be poured into almost any plastic containers, vials, etc. You only need to dip the tip of the toothpick, but under no circumstances should you fill the hole. After cleaning, try turning on the smartphone, but make sure that the port contacts or charging connectors are dry.

System errors and failed updates

System errors, or a resource-intensive application that is not completely unloaded from RAM, can cause the battery to begin to drain rapidly, causing the phone to shut down and not start again. A malicious program can behave similarly. The virus, if its task is not extortion, works in the background. At the same time, he tries to use all available resources as quickly as possible. If your Android phone runs out of battery faster than usual while in standby mode, you should check it for infection and force a reboot. Further actions depend on the results of the anti-virus scan.

If the smartphone is clean and charged normally, there is no reason to worry. Otherwise, if the device does not start or the phone quickly runs out of power again, you will need a full reset and re-setup.

An unsuccessful software update can result in the phone not responding to user actions or simply turning off. Usually, this behavior is easily “cured” by rebooting.

If there is a failure when updating the firmware to a new OS version, the situation is a little more complicated. When the phone starts, but the boot does not go beyond the splash screen, the recovery mode can save the situation. It is best to find out what to do and how to enable Recovery Mode for a specific phone on the manufacturer’s website or in the documentation for the device. When this is not possible, try universal methods. The vast majority of Android smartphones support turning it on by holding down the power and volume keys. Whether it is an Up or Down button depends on the device manufacturer. You can try both options sequentially.

Tips for using your phone battery

If you want your smartphone's battery to last as long as possible, never play games or use other programs while the battery is charging. This harms the “healthy” battery. There are special applications in mobile markets (AccuBattery) that perfectly show how much and which application takes up the charge.

Keep track of running applications on your smartphone. Usually, there are a great many unnecessary applications running on user devices. And most of them just need to be turned off. And in some cases, applications will help indicate why your phone is not charging.

Contacts

Another common cause of problems with charging a smartphone or tablet is clogged contacts. Dust and other small debris may get into the charger connector and the phone itself. The contacts can be cleaned with a soft brush, and you can also try to “lift” the fasteners inside the connector with a toothpick.

Attention! These actions are dangerous and must be performed carefully and competently. Remember that all responsibility for the gadget lies on your shoulders.

Excessive system load

When the Android system is running under normal load, the processor and other subsystems of the smartphone consume some power. But if you turn on something energy-intensive - a large game with rich 3D graphics, high-resolution video, etc., the battery charge will begin to rapidly decrease. Some try to outwit the device and charge it at the same time as playing. But it may go slowly or still decrease.

The whole reason is precisely the excessive load on the system - it wastes energy faster than it is replenished. As a result, you may end up with problems with the battery, significantly reducing its resource, because under heavy load and simultaneous charging it gets very hot. Due to the high temperature, other elements of the smartphone also suffer, their service life is shortened and there is a risk of breakdown.

So if your phone isn't charging or it's slow, check to see if you have too many apps running, especially resource-intensive ones or those that use Wi-Fi. Many people simply minimize them, but they continue to work, and even many small programs can give this effect. Bring all running apps to the screen and swipe them aside, ending their excessive activity. After this, not only will the charging speed increase, but the smartphone will also work much faster.

Repairing or replacing a faulty smartphone battery

Cable damage

Most often, smartphone batteries do not charge because the charger cable is damaged. It should be noted that in this case the problem does not appear immediately and suddenly. At first, you notice that the gadget charges normally only when it lies in a certain way . Of course, you can twist the wire for a while to get the desired contact with the phone. But sooner or later the wiring “lags” completely, and it becomes clear why the phone battery is not charging.

Next, everything will depend on what kind of charger you have. If your charger has a detachable cable, it won't be difficult to replace. If the wire is not removable, you will have to buy a new charger.

By the way, if you are an electronics enthusiast, it will not be difficult for you to simply cut out the damaged part of the cable and connect the necessary wires together, or solder them if you have a soldering iron at home. After soldering, the wires need to be wrapped with electrical tape so that the contacts do not come off again, and the cord can be used.
