Samsung A3 phone is not charging. Samsung Galaxy S3 - I9300 - began to charge badly

Alexander Grishin

If your Samsung phone is badly charged, it can become a signal of a serious malfunction in its hardware component. Therefore, to avoid possible breakage, you need to figure out how soon the phone does not charge and eliminate the malfunction. In this instruction, we will tell you what to do in this situation.

Causes of bad charging and their elimination:

Problems with devices

Defect cable, broken port covers, contaminated connector - All this can be a hindrance for a full connection of the phone to the charger. This problem is solved by cleaning the contacts of the previously turned off the device using a needle or toothpick and blowing it with compressed air. Most often, it is enough to restore the full performance of the devices of these machinations.

Damaged cable

Frequent use of the charger wire gradually flashes it, which is additionally affected by random chances during operation. Because of this, Samsung Galaxy can be charged very slowly. If there is a suspicion that it is in the cable, it is enough to take another wire for the charger and connect it to the phone. It will help - it means the answer is found.

Worn adapter

Frequent connections and switching wires negatively affect the charger, wearing and overwhelming its connectors. You can check this option by connecting to a power outlet through another charging. You also need to connect the main charger to another phone to make sure that the problem is not in the smartphone itself.

Problems with battery

Remember: You can not leave the phone on charging longer than it needs it. It is not moderately a long-term connection to the charger negatively affects the entire Samsung smartphone as a whole and on its battery in particular. It is also important to remember that the time of life of all devices is limited, so if the battery is not already the first year, most likely it is just necessary to replace it.

Wrong source of energy

Charging speed from the outlet will always be more than from the computer. Also, an important role is played by the power of the adapter, so it is important that he fit to your phone, otherwise you will see that the device is very slowly charged.

Unsuccessful update by

Sometimes new version of Android software contains errors that negatively affect the operation of the device. In this case, it is worth making a rollback to the older version.

Phone activity

It is important to remember that the stronger the phone is loaded by active applications, the more it consumes energy, and its battery will be charged longer. Want to charge the phone as quickly as possible - minimize the activity of all processes, and ideally turn it off.

If your Samsung phone does not charge and does not turn on, then, most likely, the problem is no longer possible to fix it - you need to carry it into the service.

We hope our tips will help you figure out what to do in case of bad phone charging and how to eliminate this problem. Good luck!

Android is the most popular OS in the world, and at the same time, one of the most unstable. So it happens that you wanted to put a new firmware on the old Samsung A3 or installed the system update, and the phone was cut down and refuses to start again.

At the same time, Samsung A3 is one of the best ruler gadgets, a fairly reliable satellite. But is it worth it to directly panic or Samsung Galaxy A3 can be restored independently without spending money and time going to the service? What to do, so as the Android again did not create you any problems and what should not do? What if Samsung A3 does not start after discharged? Does the screen not working and does not respond to pressing? We will answer these questions further in the text.

You should not start with disassembly of the device, thereby immediately destroying the warranty coupon. Most often, the problem lies in one of two factors:

If it starts and does not load - the OS is to blame. The reason can be another failure of a new android, or a virus, and may not be installed firmware. All this is corrected and adjusted. Have specific skills to correct the program error - no need to be able to connect the gadget to the computer.
When the smartphone turned off and does not turn on, it does not respond to charging, there can be no android here. Once the device turned off and does not start, does not respond to charging, then the battery is fault. Check the battery and charger on another device, after which try directly powering the gadget using another battery.

Before making any actions with a gadget that has been cut down, carry out basic diagnostics. Depending on those signs of life, which gives the device, it will be possible to diagnose and assign "treatment".

Do not run to the service when the device is charging, but does not turn on if you did not drop it into the water or did not douse. Rarely, but hardware breakdowns happen due to the age of the accessory.

Does not help anything from this article and do not know how to revive your "satellite"? Most likely you are one of those "lucky ones" who got premature corrosion of fees or a burnt processor. It remains only to go to the service.

Battery malfunction

If you notice that Samsung does not turn on after the charge level reached 0, and the phone refuses to respond to charging - it is necessary to suspect the battery breakdown. Test it on other devices.

Block worker, and the device is still not started and the charge sensor does not work? Could just overcome the battery, do all the same manipulations with him. Another device shows the same signs when exchanging batteries? Buy a new one, because your broke.

Problem in the power connector

And if other phones are working calmly, and yours is not. In this case, the problem may be in the power connector itself.

To begin with, connect with a proven adapter, a smartphone to a PC. The computer does not see the device, and the accessory is still not started? Then you found the problem - the connector does not work.

But to replace it yourself, if you have a guarantee on your smartphone, you should not, better contact the service. There professionals themselves will make all the work, using licensed parts and without damaging other chips, instead of fixing breakage. And if your PC saw a connected accessory, but is it still not working? What to do and why is it going on? The problem was the next update of Android.

Errors OS.

It happens that you have received an update and the phone turned off, but after rebooting it does not respond to your actions and does not respond in any way. What happened and why did the official update produced such an effect? The thing is that the developers forget about the old gland and the entire line of supported devices, which is why the new non-optimized version of the OS can "put thousands of devices within one day.

Knock update

Fortunately, this update is corrected for several clicks. Connect the phone to the power, before that, letting him lie down in 2-3 days, so that the residual charge disappeared.

The indicator should turn around if it does not respond to food, turn off the gadget and let him lie down for a couple more days. Then try again. When you see the coveted red color of the indicator, try turning on the gadget. He immediately turned off? So it should be.

Hold the power button and clamp the volume button down, you will enter the Recovery mode. After that, select Data Management and click Reset. The phone will return to the nearest backup or factory settings. If you have not had a backup memory, all media files and settings are deleted, so it is better to periodically do it.

After that, the problem with the fact that Android sharply sat down, the ground and stopped turning on, should completely disappear.

What if the smartphone does not turn on after installing the pirate firmware

After installing the pirate firmware, the screen went out, the device stopped turning on, and even recovery does not start? Most likely, the crookedly set and not fitted under the OS processor. Each custom system must be selected for a specific apparatus and its characteristics, otherwise fatal failures arise, and the device turns into a "brick". But this state is curable.

Immediately after complete discharge, connect your mobile to the computer. You need to see a response in the system, for example, the inscription "Installing a new driver". If the device at least somehow is recognized - this will be sufficient for the complete demolition of the hung system and the installation is normal.

For the same reason, the smartphone is constantly rebooted, and here you need to remove the battery, then just connect the device to the PC. Then just wait until the installation is completed and start the gadget if it does not start automatically.

What if Samsung Galaxy A3 did not turn on and after such manipulations? Or the screen caught fire and turned off sharply? Perhaps the problem is already in the hardware and it is worth attributed to the access to the service.

Conclusion

The device can turn into "brick" when the system is incorrect or unsuccessful update. The main thing is not to panic, because any program errors are easily corrected even by the manifiers.

In the future, try not to abuse the openness of the Andoid system, trying to install pirate programs or firmware. This can lead to regular malfunctions in the system that will interfere with the comfort of the device.

Nowadays, many have already become accustomed to life with a smartphone for so much that it seems terrible for a couple of days! Both the phone and the Internet, and all the rest of the utility of the smartphone made our lives more comfortably and, a little, more fun. In one day, my friend Samsung Galaxy S3 began to charge badly. Remembering the story of his appearance, I already understood that it was only in the charger. Initially, the charger that was included - charged him slowly, and I tried to charge him with an old charger from the LG phone: the connectors came up, charged quickly, everything was fine. As long as the charge input into the phone is not gradually loosened, and in order to appear the phone charge indicator, some efforts have been applied. Deciding that it was easier to buy a new charger - I did, having bought a charger in the nearest kiosk for 170 rubles. It connected normally, but he was charged slowly and in the end he was completely discharged (during charging I used to smartphone). I went to the nearest service, left a phone for diagnostics and possible repairs. As a result, this campaign cost me 1000 rubles. - they said that the nest of the entrance was soldered. I do not know what they soldered, but the result is the same - the old charger that was charged - not visible, the new charger is charged slowly. In the service, I was offered to leave a couple of days for a couple of days for further diagnostics. I decided to solve this question yourself. To begin with, I bought a new battery (original Samsung - for 700 rubles). Searching information on the Internet - found a very useful article that helped me (I hope now for sure)! At least now it is clear that the reason for slow charging was in the strength of the current. Installed a program that shows how much MA is served. The original battery, as well as the new Chinese showed the number from 100 to 300 mA. There must be a value approximate to 1000 mA. That's what he charges slowly. As a result, I made two almost non-working chargers - one: the USB-phone lace - took from the original charger and connected it to the power supply unit (the one that is turned on in the outlet). As a result, it will be charged now with indicators of 500-700-900 MA. Hooray!

The text, found by me on the forum http://mdforum.ru/showthread.php?t\u003d11132 - below:

Everything that is written below is intended primarily for Samsung Galaxy S III users (International version of the GT-i9300) with an original battery at 2100mA · h

First of all, you need to make sure that it comes to the battery in the phone

We put a small but useful program with the GalaxyChargingCurrent widget, in which we will watch only the readings of Current Max. For the purity of the experiment, the battery charge should be less than 90%, and even better less than 70%. Why? - The answer at the very end under the "Note" spoiler. Turn on the body for charging from the original (samsung) of the network adapter in the outlet and look at the menu-\u003e Settings-\u003e The battery is charging from the network (AC), and not from (USB). Then look at the galaxychargingcurrent reading of the Current Max. Ideally, for charging from the network, 1000 should be (just 1a, as written on the adapter). But if it is 800-900, then it is also normal. If when charging from the network shows 460, then the body has decided that the charge comes from USB.

Smart charging in the off state will determine which way to dig (the normal charging time of the original battery is from 2 to 2.5 hours, small errors are possible).
If the smart is turned off, the order of 2.5 hours is charging, and the inclised longer means you have problems from "Software".
If the disabled smart is charging longer than 3 hours - it means problems from the "iron".
Old / faulty / served his / dying battery can be charged faster than two hours (there are charge cases up to 100% per one! Hour).

Problems from "Software" and ways to correct

The wine can be an increased cost consumption. In other words, the battery is discharged faster than it is charging. This can occur for several reasons.

The first reason "It's you, and the second is all yours ... Sorry \u003d) No matter how funny it sounds, but sometimes the user himself is to blame. You should not use smart to full until it is charging. Playing "heavy" games or run energy-intensive applications during charging is not recommended. The more active you will use Smart, the longer it will charge. Any connection (data transmission via USB, 3G or WiFi) affects the duration of the charge, the active connection is more so, since it causes the battery warming. With an increase in the temperature for every 10 degrees, the reaction rate increases 2-4 times (Vant-Hoff ©), in this case, the process of self-discharge and current leakage in the battery increases 2-4 times, it flashes faster, not to mention the discharge. With an active connection, the charging time may increase several times and the full charge signal will not fully match the truth (temperature and time limit on the charge of the chip). Based on this, the charge with an actual telephone completely turned off 4-8 times shortens the processes destructive for the battery during charging and reduces the charge time itself. Conclusion: I put the body for charging - forget about it to complete charging. Relax yourself and let him relax \u003d)
The second reason - "spontaneous" smart consumption. You seem to do nothing, and the charge literally melts in front of your eyes, the body starts to lag, to respond to your actions with a big delay, the drawing of the interface slows down. There is also strong heating at the bottom (in the SIM card / flash drive area) - smart is heated stronger than usual (I personally noticed the heating to 49 ° C). This is a sign of working, possibly in the background, an energy-intensive application. Or an error occurred in the application, it hung and the Android tries to fix everything on their own, consuming the charge in addition to the usual. Try to stop all program running at the moment (for Samsung Galaxy S III - long pressing the Home button calls the task manager with which you can complete everything). If it does not help, then remove the body with charging, disconnect the battery for a couple of minutes, insert back and connect to charging again. In the future, you need to calculate the culprit and disable or configure again.
Third reason - Frozen battery. Do not charge the battery, after exposure to it negative temperatures, wait for it when it is heated to the surrounding (room) temperature and its energy properties will return to the initial values. When cooled, the processes inside the battery slow down. Therefore, with the active use of the phone, a premature message about full discharge is possible, although there is still a stock. The effect is similar to high inner resistance, but is reversible. Due to the slower chemical reaction, the battery simply does not have time to supply the required amount of energy, resulting in a stress drawdown. It is because of the slower processes, the charging of the chilled battery will be ineffective. Moreover, it makes it impossible. It should be waited when the battery temperature will reach room floor.

Problems from "iron" and ways to correct

Bad contact. You need to clean the USB socket in the body itself, the wire plug, the adapter socket. If you do not know how you do not know how, do not want, you are afraid - take the body to the service center or in any confidence in the confidence in the repair of phones and for the symbolic fee you will be sold not only to the USB nest, but also microphones, dynamics, etc., all Blind and smuckle (kidding). It did not help - we read on.
Faulty USB cable. There are two options: crimp the microusb plug or disassemble the MicroUSB plug and disappear it or crimp the wires along the new one. If you do not know how, do not know how, do not want, you are afraid - you will help you the new USB cable. How to choose a high-quality wire - only by scientific tyk. We try different wires and compare the results in the GalaxyChargingCurrent and charging time. Perhaps the original Nokia CA-101 cable will help you. Also remember that not all wires are the same useful - do not strive to use the wires longer than one meter. It did not help - we read on.
Faulty adapter. At the moment, one option - get a new one. Or at your own fear and the risk you disassemble your adapter, repair it and share the result. Do not forget that the new adapter must respond to two conditions: the MicroUSB connector and the output voltage / OUTPUT 5V and 1000MA (\u003d 1A). 5v necessarily, more - it is impossible, less - it is possible, but the demon is a sense. 1000mA (\u003d 1A) - the maximum that the body will take it if the charging is 2000mA (\u003d 2a) - it is not scary (the body takes only 1000mA (\u003d 1a)). The best option is a monolithic charge (without the possibility of disconnecting the adapter and wire). Not only the GNUSMAS adapter, but also Nokia, HTC and others can come. It did not help - we read on.
Faulty battery. Signs of the old / faulty / serving their / dying battery are a quick discharge and bloating. Pull out the akum from the body and look at it into the profile, for example, on the line with the connectors. If the upper and lower planes are noticeably convex - change it to a new one. The malfunction of the defective battery is the spontaneous shutdowns of the smart on the charge residue more than 5%. Before shutting down, you can notice the screen flicker. Also, a serviceable battery, charged to 100% (when the green diode lights up), can not lose more than 1% during the solar loading process. The procedure for checking the battery for a malfunction - charge until a complete charge (when the green diode lights up), disconnect from charging, turn off the smart and turn on in a couple of minutes. If the battery has lost more than 1%, the battery is faulty. 1% can be "lost" during the shutdown (shutdown of application shutdown) and during the inclusion (large number of applications in the autoloader), in the usual situation this procedure requires much less energy and, accordingly, after switching on the smart with a serviceable battery, the readings will remain 100 %. It did not help - we read on.
Faulty phone. There are two options for answering: Krusky and Delchev. And if seriously, we repair in the service center or in any confidence-building, the office on the repair of phones. Or buy a new phone.

and yet (some helped):

Remove the /data/system/BatteryStats.bin file After deleting the named file and reboot, the charging problem is immediately solved. If the problem is repeated in the future, it is necessary to remove this file again.
Battery calibration. To solve all problems with charging, you must calibrate the battery.

Note: The charge time of all Li-Ion batteries at the initial charging current in 1C (numerically equal to the nominal value of the battery capacity) is an average of 3 hours. The full charge is achieved at a battery voltage equal to the upper threshold, and with a decrease in the charge current to a level, approximately equal to 3% of the initial value. The battery during the charge remains cold. As can be seen from the graph, the charge process consists of two stages. On the first (hour with a small) voltage grows with an almost constant initial charge current in 1C until the first achievement of the upper stress threshold. By this time the battery is charged by about 70% of its container. At the beginning of the second stage, the voltage remains almost constant, and the current decreases until it reaches the above 3%. After that, the charge is completely stopped.http://www.ixbt.com/mobile/review/lipol.shtml.

Infinity, especially for a daisy club.

Mobile phones have become an integral attribute of each person. It is difficult to imagine life without communication, because with their help you can call or send SMS at any time, and anywhere. What to do when this "assistant" stops working? Do not independently solve the problem if there are no special knowledge, it will not be possible to repair the device. Today we will analyze the question of what to do if the phone does not charge at all and does not turn on?

Such attempts can harm the gadget even more, and as a result, it is possible to get expensive and long-term repairs. And the most discerning will be if the mobile phone does not turn on and does not respond to charging due to a broken charger or breakage of the power button.

The only thing that the owner of Android can do is remember under what circumstances he stopped working. If water fell into the phone samsung, then it may not be included and not infected because of the fluid that fell there. If you continue to continue to charge, then the board can be spoiled. And this is a very serious breakdown.

Samsung does not charge

What if Samsung stopped responding to charging? There are many reasons for here

First you need to check the cable, maybe they frown somewhere. If everything is in order with them, the reasons can be in the connector.
Faulty charging connector. For subsequent work, it must be changed.
Samsung phone may not be charged due to damaged printed circuit board. In this case, the diagnosis and determination of the degree of damage, which will play an important role in the repair of equipment.
Broken power controller. In this case, the output will only replace the damaged part.
Samsung is bad and slowly charging. The reason may be a power circuit breakdown. To determine the degree of damage, it will be necessary to diagnose. It will be installed on its basis, which led to a malfunction.
Other problems for which Samsung does not turn on and is not charged, which can be installed only after diagnostics.

In order to understand how to act further, you need to know about the causes of malfunction. If the phone does not turn on and does not charge, then the breakage can be hidden in any piece of equipment, which will help the experienced master, making the diagnosis.

If the smartphone after charging does not turn on, it may be in the poor battery charge level. It would seem that the battery was charged, it can still use a day, but in fact it sits in a few hours. The main reason here will serve too large number of unnecessary functions in Android. To the battery does not discharge and the device did not disabled at the most necessary moment, you just need to turn off unnecessary functions in Android.
To understand why the phone does not turn on, you need to press the "Enable" key for a long time if the reason lies in the battery, then it will give a signal of "life", and will quickly turn off. If the probability that the battery is simply worn out, you will have to buy a new one.
Samsung may not be included after charging due to breakdowns of the charging cable. It is very easy to check. If after a pair of minutes the smartphone does not give signs of life, it means that it does not charge, and the cause of the charger can be caused. In modern smartphones, charger, and headphones, and other devices are connected through one opening. He simply can wear out, the contact pads are erased over time, it will not be possible to restore them, it will help only replacing the charge module entirely. You can check the charging breakdown using another device you want to connect to the phone.

If Samsung after connecting to charging cable, still flashes and does not work properly, then the reasons may be two.

The first is overheating, as a result of which the battery does not receive energy.
The second is the use of recharging that does not fit your device.

Fault Buttons "Enable" and "Disable"

The Samsung phone may not be included after charging due to the manufacturer's marriage. Most often, the power button does not work in the fault of the manufacturer itself, as well as as a result of the falling of the smartphone or its falling down. If the Samsung phone does not respond to charging and does not turn on for this reason, it must be shown by a specialist.

Problems with PO

Software failures can also be the reason that the mobile does not charge and does not turn on. Perhaps a certain update or firmware was established, which is not supported by them. In this case, there is a failure or damage to the system. Sometimes, if you wait, Smarfton can earn again.

Mechanical damage

Sometimes the phone is not charging and does not turn on due to drops or heavy items. Very often does not turn on the phone due to falling it to the floor. What if all the listed reasons are not suitable, and the phone is still not turned on and does not charge?

You can try to remove the USB flash drive, the SIM card or battery may have departed any contact. If these manipulations did not help, it means that the breakdown is very serious and it is worth contacting the master.

What ways you can enable the phone

If Samsung does not turn on and does not charge, you can try using the SAMSUNC Technical Support Council:

Press and hold the "Volume" button down simultaneously with "inclusion". Hold in this position for 10-12 seconds.

If after that the phone earned, then the reason is most likely in the usual failure of the device. If after that samsung does not turn on and does not charge, what to do? In this case, the optimal solution will need to appeal to a good master in the repair workshop, where they will make diagnostics on professional equipment and solve your problem. Do not advise yourself to dig in the courtyards of the phone, you can block the firewood and increase the cost of repair.
