Alcatel is not charging. The phone is not charging: possible reasons and solutions. Low or high battery temperature

One of the common malfunctions of Alcatel phones that people contact our service center with is that the smartphone charges slowly and takes a long time and quickly discharges. What could be the reason and what repairs are needed:

• Non-functional or inappropriate charger;
• Damaged charging connector;
• Faulty power controller (CP);
• Moisture ingress;
• Defective battery;
• Impact or fall;

Faulty charger

Before taking your smartphone to a service center, check your charger by replacing it with a similar one. If your smartphone charges faster, the problem was with your charging, or you may have used the wrong or faulty cord or cable.

Damaged charging connector

In case of prolonged or careless use, the Alcatel phone charging connector may become loose and stop charging the Alcatel phone. First, you need to bend the power cord - at different angles the Alcatel phone begins to charge, but over time this can lead to damage to the battery or power controller on the motherboard of the Alcatel phone, so it is better to prevent damage and subsequent repairs to the Alcatel phone board and replace the phone charging connector in time Alcatel.

Faulty Alcatel phone power controller

Over time, as a result of power surges or defects on an Alcatel phone, the power controller (CP) may fail, which will be accompanied by the following symptoms:

• Alcatel phone does not turn on;
• charges slowly;
• reboots;
• discharges quickly.

If the power controller is faulty, the Alcatel phone's motherboard will need to be repaired.

Moisture ingress

Protect your Alcatel phone from water and moisture, as the consequences can be dire, such as corrosion on the power connector. If, after your smartphone has been flooded or wet, it begins to charge slowly, you need to clean or replace the power connector on your Alcatel phone. Also, if liquid gets in, the Alcatel phone battery or motherboard may fail.

Bad battery

If your Alcatel phone begins to charge slowly 2-3 years after purchase, pay attention to the battery. In case of severe wear and tear, the Alcatel phone battery must be replaced. The battery needs to be replaced every couple of years. Battery wear and tear depends on how often you charge and discharge your Alcatel phone and what chargers you use.

Hit or fall

Mechanical impact on an Alcatel phone has a detrimental effect on both its appearance and the performance of the Alcatel phone as a whole. If, after shocks and falls, your Alcatel phone begins to charge slowly, it is quite possible that one of the many elements on the board has become unusable. In this case, diagnostics are necessary to determine the malfunction and the cost of repair.

The second most common problem, and no less annoying, is that the Alcatel phone does not charge. Everyone knows that without this, not a single device in the world will simply be able to work autonomously. In fact, the charging process itself is vital for technology. However, this does not change the fact that for certain reasons this does not happen at all. If your Alcatel smartphone does not charge, this may mean that there is some serious problem with it that requires professional intervention!

After all, the matter concerns the power plant of the device, which should be inspected and repaired exclusively by professionals. However, what could cause a situation where an Alcatel phone does not charge? The most important malfunction that can occur is damage to the charging socket. Naturally, without it it is generally impossible to talk about the correct supply of power to the battery. It can break quite easily - you just need to drop it a couple of times on hard surfaces or get liquid under the body. Speaking of the battery, if you notice that the battery of your Alcatel smartphone does not hold a charge, this is a serious reason to contact our specialists, because it has already outlived its usefulness and requires immediate replacement. In short, everything that happens to the power unit of the device must be carefully monitored, because the operation of the device itself depends on it.

Each of us has encountered a situation where a smartphone refuses to charge. Can this problem be solved at home or will I have to take the phone to a service center? Let's find out!

Reasons why your phone won't charge.

First of all, it is necessary to answer the main question: what exactly happens to the smartphone while charging? As a rule, the most common situations are when the phone does not respond to charging at all, or the charging is on, but the phone does not charge, or it charges, but does it very slowly. So, first, let's look at the main reasons why the phone does not charge at all.

Checking the socket/USB cable/adapter.

If we want to solve the problem, then we need to consider various options, and we need to start with the simplest one. First of all, you should check the serviceability of the outlet. You can do this with a multimeter; if you don’t have one at hand, then simply try to charge the phone from another outlet. If charging started, then it was the problem.

The second most common problem why the phone won't charge is a faulty USB cable. It is the cables that most often become unusable - they burn out and break at bend points. Replace it. Didn't help? Then we check the adapter in a manner similar to the previous one.
It should be noted that in some cases it happens that the charging is working properly, but the phone does not charge. The reason is simple - the charger does not match the phone. In this case, we advise you to take either a native charger or a similar one with a similar amperage. For reference, battery capacity is measured in mAh, and chargers are available at 1A, 1.5A and higher. Try both options. One of them will definitely suit you.

For example, if Sony Xperia phone won't charge, then you may need to charge at two amps. This information is usually written on the packaging of the phone or on the charger itself. Sony phones may not charge only because there is insufficient current and the electronics are blocking such a charger.

At this stage, as a rule, it becomes clear whether the reason for the lack of charging is in the charger or in the smartphone itself.

The phone stopped charging due to the USB connector.

If the problem is in the USB port, then there are only 2 options - either regular cleaning of the contacts will help you (for this you will need a paint brush and a toothpick), or just replacing the USB connector (which can be done at any repair shops).

It often happens that a huge amount of dust and dirt gets into the USB connector, so you should try to clean the charging port with a regular paint brush. Use a toothpick to “lift” the small fastener inside the USB port. Everything must be done very carefully!

Quite often, cleaning the contacts allows you to restore normal operation and the phone begins to charge as if nothing had happened.

But, if nothing worked for you at home, then in this case you will have to take the phone to a service center. For example, if you have Samsung Galaxy phone won't charge, then the service center will very easily find spare parts for it, such as a MicroUSB connector or battery, but if you Alcatel phone won't charge or Philips, then in this case the search for spare parts may take longer or you may even have to buy them in Chinese online stores.

Software problems.

If your Android phone does not charge, the reason for this may be either incorrectly installed programs or a failure in the system itself.

In this case, you will need to reset the settings to factory settings or completely flash the phone. You can reset the settings through the menu.
For example, if you have Huawei phone won't charge and you would like to reset the settings, then to do this you need to do the following: go to the menu - advanced settings-restore and reset-reset settings. If desired, you can back up your data.

Most Android phones provide the ability to reset settings through “three buttons” - this means simultaneously pressing the volume rocker up and down + the power key.
For example, to reset a Samsung device, you need to press and hold three buttons: power key + Home key + volume rocker up.

If this option also does not suit you, then the problem is definitely the battery.

Charging is in progress, but the phone battery does not charge.

Remember how long have you been using your smartphone? We love our expensive phones so much, and we really want eternal life for them, but alas, batteries are also prone to old age. Over time, even the strongest batteries stop holding a charge. This is because lithium-ion batteries, which are now used in most smartphones, have a lifespan, which is determined by the number of full discharge cycles (to 0%). Legitimate advice: to extend the life of a lithium-ion battery, try to charge your smartphone more often and prevent the battery from being completely discharged.

Sometimes, problems with the battery are even visible visually. If some kind of deformation occurs or the battery is swollen, this will also affect the appearance of the phone. For example, not only the outer cover of the phone may be deformed, but even the screen may be slightly squeezed out.

Monitor such changes carefully, otherwise they may lead to more dire consequences than simply being unable to charge.

The phone takes a long time to charge.

This problem occurs no less often. It may occur due to the fact that the device is running some energy-intensive applications that consume energy faster than the smartphone charges. These include “heavy games”, as well as enabled Wi-Fi, Bluetooth, geolocation, etc. So, if your phone is charging slowly, just turn it off before charging.

We also do not recommend charging your phone from the USB port of a computer or laptop; usually they are supplied with no more than 500 mA, which is clearly not enough for normal charging of phones. Of course, most phones will charge from the USB port, but extremely slowly, and some phones will not accept such charging at all.

The phone shows the wrong charge percentage.

If the phone takes a long time to charge, then it is not always the case that the applications are running. Sometimes situations arise when your operating system does not correctly remember the energy consumption mode, which causes errors in battery management. How to understand this?

Yes, very simple. The most important sign is a fast-discharging battery (and the smartphone turns off when the charge is already 20-30%) and very slow charging of the smartphone. In this case, do not rush to run to the store for a new battery. Try to calibrate it first.

To calibrate the battery, perform five complete charge/discharge cycles of the phone. That is, when the phone runs out of charge and turns off on its own, you need to charge it until the required maximum mAh is reached. After the last fifth full charge cycle, disconnect the charger, remove the battery, reinsert it after 10-20 seconds and perform a hard reset (as described above).

But sometimes the problem may not be the battery itself. For example, if you have Meizu phone won't charge, while showing one percent charge, then in fact the phone is charging, but the only thing is that a software glitch has occurred. In this case, you will need to completely turn off the phone and turn it on again. And the problem with 1% on the Meizu phone will be solved.

If none of the methods helped you solve the problem, then most likely you won’t be able to solve it at home at all. We advise you to contact a service center to have your phone repaired.

The situation when the battery on a smartphone runs out and there is no way to charge it is critical for many. That is why it is very important to find out why the phone is not charging and choose the best option to fix the problem. The instructions are suitable for all models and brands: iPhone, Alcatel, Asus, Lenovo, Phillips, Prestigio, Sony Xperia, HTC, Samsung, Xiaomi, Umidigi, Leagoo, Doogie, Huawei, HomTom, etc.

The charging process involves several things at once: the charger, consisting of a plug, tip and cord, as well as the battery itself. That is why, if the smartphone does not charge and does not accept energy from a standard or new purchased “Chinese” charger, we check each unit separately.

1. Damage or clogging of the connector.
2. The cord comes off (play) or the plug does not match the socket (for example, micro-USB is not suitable for Type-C and Lightning).
3. Software glitches.
4. Broken wire, “fragmentation” of the wire.
5. The use of dubious Chinese “crafts” for 20 rubles, the veins in the cheap versions are very thin and break with little impact.
6. The wire is too long; the shorter the length (30 cm is ideal), the less current loss. But here again it all depends on the quality.
7. Battery malfunction (swollen, overheated, deteriorated from old age).
8. Burnt-out power controller or protocol incompatibility.
9. Heavy CPU usage, such as heavy gaming or watching 4K movies.
10. Failure to comply with temperature conditions. The battery replenishment process does not occur at sub-zero temperatures.
11. Forgot to “peel off” the protective sticker after purchasing a new gadget.

If the phone charges normally, but quickly discharges, the battery is temporarily worn out. The standard battery life is from 3 to 5 years (equivalent to 300-500 charge-discharge cycles), after which it begins to discharge a couple of hours after charging, or does not accept it at all.

There is another factor: a virus infection has occurred that causes problems in the power supply system.

Sometimes it shows that the charge level is increasing. But in reality, the battery does not take or does not respond to the supply of energy and after disconnecting the cable, the voltage sharply drops to zero.

Diagnostics

To diagnose yourself, take the test. The virtual assistant will identify the problem and tell you what to do.

Not charging

To understand why your phone is not charging well or the power indicator is not displayed on the display, you need to follow a few simple steps:

1. Take a non-native charger and connect it to your smartphone.
2. Change the USB cable to a new one (pay attention to the connector, currently 4 main ones are used - USB Type-C, micro-USB, Lightning and the outdated mini-USB).
3. The indicator lights up, which means the problem is a charging fault.

If the other charger does not work and does not bring the charge level to full, there is a high probability that the problem lies in the software, battery or cell phone connector.

The first step is to carefully clean the nest. If this does not help, it is recommended to take the gadget to a service center, because... It will be difficult to fix it yourself.

A faulty power supply can be repaired by the owner himself by purchasing the necessary replacement part, but due to the low cost of USB cords, it is more logical to purchase a new one.

How to check the connector

Diagnosing the condition of the USB cable socket involves examining it in bright light using a magnifying glass. If it is dirty, you should clean it with a thin brush dipped in alcohol. Dust and debris create poor contact between conductors and interfere with the flow of current.

What to check:

• The nest does not wobble in the body.
• No contamination observed.
• There is no visible deformation of the module (bent contact groups, changes in geometry, etc.), and the smartphone will not respond to charging.
• Visually there are no drops of water or moisture.

If this is not the case, you will have to look for the reason in another part.

How to check the battery

The above method showed that the smartphone does not receive energy not due to a burnt-out memory, but due to a damaged cable. If the cable is turned on and it says that charging is in progress, but the phone does not charge, there is a high probability that the faulty battery needs to be replaced.

• The battery is swollen and/or protruding from the case.
• The battery is not fully and slowly charged, no more than to 60-90 percent - only replacing the module.
• If the charger is working properly, the cell phone does not charge or does not see charging, although the process is ongoing.
• Download the utility to check the remaining capacity.

This means you need to test the battery: simply replace it with another analogue and see if the indicator lights up when connected to an outlet. This method will not work for Apple technology!

Signs of a virus infection

The main symptom when software is infected with malware is the absence of an indication. It can also freeze constantly, and if previously the battery lasted two days, then after getting a virus it will be discharged in 5-12 hours (i.e. for a very long time).

To troubleshoot problems, you need to scan your phone using an antivirus program. If infected files are detected, they will be deleted automatically, and if this is not possible, you will have to clean the system manually, removing the application itself that contains the viruses.

How to charge without a standard charger

In any cell phone store you can find a universal charger suitable for both smartphones and iPhones. The battery can also be any.

In another way it is called a “frog”, and using such a charger is very easy:

1. We insert the battery into the clamp, the “plus” and “minus” contacts must match.
2. We insert the “frog” into the outlet and leave it to charge for several hours.

Question and answer

% stands still does not add

Or the process only runs in the off state:

1. There is not enough charger current. For example, the charger produces 250 mAh with the required 1000 mAh.
2. The USB cord is of extremely low quality and does not allow voltage to pass more than 4.5 volts, which is critical.

Cannot charge from computer/laptop via USB

• Most likely there is not enough current, for example due to artificial limitations on the computer’s motherboard. Or the restrictions are triggered at the software level, you will have to look for new drivers for the USB hub.
• This can happen if the cord is old or “works every now and then.” Somewhere in it the contacts are shorting. This is especially true for “shaggy” iPhone cables. In general, buy a new one.
• Another trivial reason that is relevant for different variations of Type-C is protocol incompatibility. Each Type-C contains a small chip responsible for data and energy transfer. At the same time, there are a bunch of standards, for example, some cables can “refuel” a full-fledged laptop battery, while others can only exchange data.
• It happens that the USB connector in laptops is longer than the standard connector from a smartphone, and the hardware simply does not touch.

From the cigarette lighter

If car charging from the cigarette lighter does not work, a similar diagnosis is carried out (see previous sections), because The principle of supplying energy to the battery is the same everywhere.

From the radio

From power bank

Standard situation, most often the PowerBank does not have enough output current. Or it's time to buy a new power bank. In the case of Type-c, it may not allow charging the battery.

From wireless charging

Not all models support the wireless power transfer function. First, make sure that the manufacturer has included this functionality in your gadget.

If you are sure that wireless transmission is implemented at the hardware level, but the charge does not work, you need to check:

• Whether the station is not connected to the network.
• Does the device move/shift from the center of the site?
• Not wearing a thick case or magnetic dock.
• The cable is not inserted or data is not being transferred to the computer.

If this doesn’t help, check the installation itself on another device; if everything works as it should on it, take your device to the workshop. Very similar to the problem with the wireless microcontroller.

Writes moisture detected

There are two options here:

1. The device fell into water or another liquid (beer, wine, juice, tea, toilet). What to do is written.
2. There was a strong temperature difference, for example, we came from a cold place to a warm room and condensation formed on the board. Wait a couple of hours and everything will return to normal.

Low or high battery temperature

The operating temperature of modern batteries is from +3 to 45 degrees Celsius. If these values ​​are exceeded, the controller limits the flow of energy to the batteries. It is necessary to cool/heat the phone.

There was a strong blow or fall

Lithium-ion “products” do not like strong mechanical impact, and can fail due to strong impacts and falls. This is just replacing the module with a new one.

After a long period of non-use

A deep discharge has occurred - use the “frog” to “push” and try to revive the battery.

To extend the life of your iPhone or Android smartphone, you need to follow these recommendations:

• Do not let the gadget fall.
• Do not discharge the battery too often (no more than once every 2 months) completely to 100 percent. It is ideal to keep the level from 20% to 80%.
• Do not abuse the use of a low-power universal charger, even a new one.
• Install anti-virus protection on your phone.
• Do not leave the device in the cold or heat (operating temperature from +3 to 45 degrees).

Conclusion

Many owners of smartphones (both Android and iOS) encounter the problem of lack of charge, but to carry out diagnostics it is not necessary to take the phone to a service center: just use the instructions to find out the reason.

If the gadget does not charge due to a battery malfunction or has stopped receiving power due to the USB connector, it is recommended to contact a technician. In other cases, it is enough to replace the damaged charger with a new one, ideally an original one.
