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 enable Android battery percentage display

To record more accurate indicators of the charging process, people are looking for how to make charging percentages on Android so that they are displayed instead of the intuitive painting of the battery icon, which is activated by default. Displaying the battery charge percentage on Android is very convenient, and it is very simple to do:

Go to the device settings.
Find the item “Battery”.
Select the “Charge level” parameter.
Activate the charge percentage display.

Battery percentage on Android

In conclusion, we can say that following the competent advice and step-by-step instructions that were given in this material will preserve the “health” of the battery for a longer period. If the charging percentage on Android does not show correctly, you must first activate this function and then calibrate the battery.

Why doesn't my phone show that it's charging?

This situation occurs as a result of a malfunction of the power source (socket, USB port), mechanical damage to the charger, or its incompatibility with the smartphone. You can determine if the power adapter is faulty by its temperature. If it is not optimal (the case is cold or excessively hot), then problems with the adapter are obvious.

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.

Why isn't my phone charging even though it shows that it's charging?

This happens when the battery is “old” - its service life is coming to an end or has already expired. For example, a Samsung phone does not charge or discharges much faster without a charger connected to it due to a decrease in the quality characteristics of its battery. The only solution to the problem is to completely replace the battery. Most modern smartphones have a non-removable battery. If you do not have the skills and experience to remove it from your smartphone, it is better to contact a specialized service for this service.

Keyboard

The input device consists of groups of conductive tracks; when you press a button, they close, which is processed by a multicontroller located on the motherboard.

Keyboard failure usually occurs after it is flooded with liquid - in this case, the buttons usually fail 5-6 at a time. In this case, you need to replace the laptop keyboard with a new one. In rarer cases, the keyboard mechanism breaks down or gets clogged (the buttons are harder to press), in which case the keyboard can be repaired.

Force restart OPPO A3

First, let's look at several methods associated with recovery through Recovery mode. You can get into it if the gadget is charged more than 15%. At the same time, by connecting the charger, you can verify the integrity of the screen and the functionality of the USB connector.

So, if the phone responded to connecting charging and displayed the process of replenishing the battery, then after reaching the appropriate level, you can proceed to the following manipulations:

Press and hold the power and volume up buttons at the same time. You should hold them like this until the phone starts to vibrate. The boot screen will appear and vibration will follow, then you can release the power button. Important: sometimes the combination with the volume down button works, not the volume up button.
In the menu that opens, select “Reboot to system” (in some versions – “Reboot system now”).

The device should immediately reboot, followed by a normal Android boot. By the way, if the gadget does not charge, it is recommended to try other USB cables and chargers. It is possible that the problem lies precisely in them, and the phone is simply dead.

Motherboard

Carries out the main work of the laptop; it contains the processor, RAM, video card, other chips and connectors.

Breakdowns occur when the motherboard overheats, when liquid gets in, after a shock or fall, during power surges, over time (after 5-7 years).

Symptoms of a board failure:

The laptop does not turn on and does not respond to the power button;
no image appears when turning on the laptop;
constantly reboots;
the system does not boot;
an error appears when initializing drivers;
