The most common problems when connecting charging

Despite the fact that the iPhone is considered a very reliable device, various breakdowns can occur during use. They are most common when charging an iPhone.

The most common battery problems are:

  • iPhone charges only when turned off
  • iPhone charges very slowly when not turned on (off) or on
  • the display shows the status “Not charging”
  • the percentage of charging does not exceed some value, n
  • the error “The cable is not certified” is issued

Problems with iPhone charging poorly can be varied. You can determine the malfunction yourself by following certain steps.

How to restore the recharge function if components are faulty

Sometimes Apple smartphones won’t charge due to faulty internal components of the device.

The lack of charging may be due to the breakdown of such gadget elements:

  • battery
  • power controller
  • connector for charging the device

If iPhone charges only when it is turned off or does not fully respond to charging, and self-actions did not lead to the restoration of the device, seek help from experienced specialists.

How to remove from the screen the inscription “accessory or cable is not certified”

IPhones of the latest models are able to recognize genuine USB cables, because the manufacturer began to install a special chip in the plug. However, today you can take the risk of buying, so to speak, “propped” charger, made by the Chinese. But a fake will not be able to provide the proper charging speed of the battery and can lead to serious damage.

If the display shows “accessory or cable not certified”:

  • turn the cable off and on again
  • if the problem recurs, use a charging cable that you are sure of originality
  • try updating the software (it may have crashed)
  • reboot your smartphone

When using a non-original cable, do not be surprised if you see the phrase “this cable or accessory is not certified” on the screen of your device. The manufacturer quickly determines what type of cable is used and removes the warranty if a Chinese counterfeit is used.

What to do when there is no battery power

If your device doesn’t charge when you connect your iPhone to a working power supply or USB connector, there could be many reasons.

Try to fix the problem in the following ways:

  • turn off and reconnect iPhone to power source
  • If iPhone is completely discharged, leave it off and recharge for about half an hour
  • put your smartphone on charge from another outlet or USB port

If the listed actions do not give a positive result, the cable or the original battery may be faulty. Check the integrity of the wire, and if damage is found, purchase a new charger.

What to do if the status is “No charging”

When smartphones and other Apple equipment are charging, you can see the charging indicator in the upper right corner. If in the process of recharging the gadget you find that power is not being supplied, source of greater power is required.

To avoid such problems, you should adhere to certain rules:

  • charge the gadget only with original power adapters manufactured by Apple and included with the smartphone
  • If the device does not charge when you plug the cable into the computer, use a power source with a higher wattage
  • do not charge your smartphone with external USB adapters from third parties

Only by using original iPhone accessories, you can be sure that the power source is sufficient to recharge the device.

What to do when charging the battery slowly

The new device charges quickly enough at first. However, after a certain period of time, many iPhone owners notice that the battery level increases very slowly.

If your iPhone is charging but very slowly, you can use a higher power adapter to get started, or try the following methods:

  • try charging your smartphone using a different USB port
  • check the Lightning port for visible mechanical damage
  • Determine the integrity of the smartphone charging cable

If you carry iPhone without a protective case in your pants or purse, try cleaning the connector to remove dirt and dust. This can be done with an ordinary toothpick. However, be careful when performing mechanical actions, do not damage Lightning.

The main causes of the malfunction

When iPhone doesn’t charge well or runs out of power very quickly, many owners start looking for the cause in a faulty smartphone battery or cable. However, you may have completely serviceable original components, do not rush to change them.

Common reasons why a smartphone only charges when it is turned off are:

  • software malfunction
  • dust and other small particles entering the device
  • defective USB port
  • using a non-original cable, battery
  • insufficient voltage in the mains

To restore an iPhone, you need to accurately determine the cause of the breakdown by analyzing the features of the malfunction. You can independently understand why the iPhone charges only when it is turned off, and you can only determine how to fix the problem by sequential manipulations.

Why iPhone only charges when it is turned off?

Why does charging only go off

Thus, the switched on gadget consumes energy for its work plus to replenish its charge. If the device is charged only when it is turned off, then all the energy goes exclusively to charging the device.

Reanimate the battery

Problems with batteries are familiar to all owners of cell phones, iOS or Android, it doesn’t matter. Over time, the substance of the battery begins to “deteriorate”, the more charge-discharge cycles, the less the electric capacity becomes and the sooner the phone sits down. Traditionally, the “death” of the battery occurs in 3-4 years of operation, the number of cycles exceeds 500-700 and obstacles begin. One of them is that the iPhone can only be charged when it is turned off. Now, in order, what is worth checking and where to put your hands.

READ  How to factory reset iPhone

After checking the memory and the adjacent devices, maybe even replacing them with the latest ones, removing all unnecessary applications and generally turning off the phone, but all the same, the iPhone charges only in the off state, then we run over to the most difficult stage.

The ideal option would be to purchase the latest battery and install it instead of the damaged one (I will attach a video on how to create a substitution), but this is not always realistic due to events and the user’s lack of repair experience.

The only option is to leave the unfortunate iPhone turned on for the whole night, this is unlikely to help return the device and the battery in it, but it’s worth a try.

It is better to resuscitate a non-removable iPhone battery not at home, but even better, it will be given to the torn apart of experienced people who know a lot about the safety and high-quality repair of mobile phones.

Resetting iPhone to Industrial Options and Updating iOS

This measure will allow you to return to working capacity in 20% of cases, most likely the case is different, but as a measure before replacing the battery, it is worth testing, at least make sure 100% that the matter is specifically in it.

How to correctly reset to industrial options, read in this article for us, how to update read here.

Why iPhone can only charge when turned off? This question remains to be asked to the moderating battery, this will be the final and saddest part of the article. So sad that you have to leave the house and spend money on smartphone repairmen.

Close and remove applications

After a couple of years of labor for the benefit of the user, the phone battery may not produce the required amount of energy. Then a situation arises, the iPhone 5, 5s, 6, 6 plus can only be charged when it is off. Before opening the case of the accessory, we will try to turn it on while charging, even if the iPhone is not charging while it is on. In this mode, we will close and remove the “energy eaters”. applications that consume energy in the background. Let’s reboot the device and see the reaction.

If it helped, unsurpassed, you have to replace the battery, it didn’t help. it doesn’t matter, read the article further. But in any case, you got at least to replace the battery, at worst, to replace the power controller and everything that will be sentenced to replace the master.

Examining the cable

Now let’s take a closer look at the cable itself. It does not have to be kinks and kinks, if they are, we try to change the wire, taking it from a neighbor for a while. in 80% of cases, he is the culprit, if this is so, we feel free to send the lace to the trash bin, repair is not advisable, even if it is a unique device that comes with the phone.

iPhone charges only when turned off. iPhone charges only when turned off

Summing up the result, I can announce that if the first sections of this article for us did not help you, it means, without the help of others, to find the answer to the question why the iPhone charges only when it is in a disconnected state will not work. I recommend contacting the service center, where they will help revive your electronic friend for adequate funds. Your intervention is likely to increase the cost of repairs. Be careful and attentive and everything will work out.

Of course, the South American company “Apple” designs, makes and supplies to the mobile phone market excellent devices that justify their cost due to the corresponding technical features and an optimized operating system. Only at the expense of its devices the company can be called standing out against the background of its own con

Quite often the discrepancy lies in the charger itself. They are not as durable as we would like, and the constant insertion of the cord greatly reduces its life. Traditionally, this does not happen overnight. At first, you start to notice that the phone only charges in a certain position. You start to twist the charger, fix it in a bent state in order to get the desired charge. But at some point, the cord stops working at all.

Attention: if your mobile is one of those models where there is access to the battery, then the temptation is great to connect the wires directly to the battery. In an emergency, this method will work. It is quite easy to cut off the adapter, strip the wires, substitute them to the battery contact. But such experiments spoil the battery itself, it ceases to hold a charge. Later, you will have to take not only the charger, but also the newest battery. So don’t use this method.

It happens that the phone indicates that it is charging, but the charge still “melts before our eyes.” Even if you connected it to a network or a power bank.

If everything is in order with the cord, the reason may lie in the faulty connector. This discrepancy also manifests itself evenly. Traditionally, the device could not be charged right away, it was necessary to move the charger a little in the area of ​​the connector. The prerequisites for a breakdown are traditionally in the careless use of the phone. At risk are people who love to put the phone on charge, but continue to use it. Also, the prerequisite for this difficulty may be the age of the mobile or just a bad connector. Cheap chargers, which move the contacts, also greatly shake the connector socket.

You can try to solve this problem yourself.

  • Disconnect the device. Take out the battery if possible.
  • Take a small, narrow object (toothpick or needle).
  • Insert the needle into the USB port and pull the small hardware upward. This must be done quite lightly and very carefully.
  • Insert the battery. Check if the phone is charging.

If it was not possible to fix it without the help of others, then use the services of professionals. The problem is solved quickly and inexpensively. After repairing, try to charge your phone less often. Try to charge your phone completely once a day.

Due to a bad update or harmful viruses, the phone may not show that it is charging. These tasks are solved in different operating systems in different ways.

  • Use programs to optimize system performance (CCleaner, Clean Master, Smart Manager).
  • Install antivirus and check the device for viruses.
  • Reset system to industrial options. In order to do this, find the “Settings” menu item in the phone.

If the problem was specifically in the operating system, then the extreme method will definitely help. Just do not forget to transfer all essential data to a flash card.

  • Force restart iPhone. To do this, immediately hold down the Home and Power keys for about 30 seconds.
  • If a discrepancy appeared after the update, then you can simply cancel them. To do this, connect your device to your PC. Open iTunes and make a backup.

We clean the connector

You can try to clean the connector, it often becomes a prerequisite that the iPhone boots and only works on charging. To do this, we take an ordinary cotton swab and carefully, without fanaticism, clean the place where the lightning plug is connected.

Oxidation or contamination on contacts

Contacts can also be the reason why the phone only charges when it is off. We recommend swiping the alcohol cotton over the contacts on the phone and charger. The point may be precisely in them. Unfortunately, this method rarely helps, but there is always hope.

Why does the phone only charge when it is off? Causes and solution of the problem

There are various reasons why the phone only charges when it is off. And this is a problem, because a modern gadget requires a large battery supply, consumes a lot of energy, and sometimes you have to charge it during use, watching a movie, playing a game, etc. It is extremely inconvenient to do this only in the off state, because this way the device most of the time trite unavailable.

Anyway, this is unusual. charge the phone only when it is turned off. But it is worth noting that for some models of tablets and smartphones, this is the norm provided by the developer. It’s stupid, but it is. But more often than not, if a Meizu phone is charged only when it is turned off (this also applies to other brands, but on the forums people often turn to Meizu smartphones), then this is a software or hardware problem. Let’s figure out why this is happening.

Other problems

Sometimes it is impossible to figure out why the phone charges only when it is turned off. Even specialists cannot always give an answer. The reasons can be anywhere. For example, a microcrack could appear in the power circuit during a fall. Also, some kind of micro-rupture could have occurred inside the cable. It is impossible to determine all this at home, and sometimes it does not work even in workshops.

But if you cannot solve the charging problem, then you should not be upset. By itself, it is insignificant. The main thing is that the smartphone works fine and performs its functions. All the same, most users put their phones on charge only in the evening, when they themselves go to bed. And there is no special need to charge it during the day. So sometimes you just need to accept and not pay attention to such trifles.

FIXED: iPhone 5 / 5C / 5S Only Charging When Turn Off

The phone only charges when it is turned off due to firmware

The very first and most widespread version. firmware. This is especially common in Chinese smartphones: ZTE, Meizu, Xiaomi, etc. These phones are sold based on the Chinese shell, and there is no native localization for it. Therefore, users often install third-party software. unofficial firmware.

It is logical that such firmware, developed by amateur programmers and installed by a user without such skills, can slow down. over, the problems can be very diverse: a weak range of brightness control, strong heating during passive operation, rapid battery discharge, a conflict with the charger. It is worth noting that it is precisely because of bad firmware and software problems that something like this happens most often. This can also be related to the hardware, but it is extremely rare.

Defective power supply or battery

It is logical to look for the reason in the power supply. he can also be the cause. It is easy to check if the power supply is working properly. To do this, you need to try using it to charge another tablet or smartphone. If everything goes well, then the problem is not with the power supply. You can also try to charge the problem smartphone using a laptop or computer by connecting it via USB. If the charging process is activated when the phone is on, then you should look for a problem in the power supply.

There is also another rare reason. weak voltage in the network. If it falls below 220 V, then some phones and tablets may not charge when switched on. Sometimes the power supply is so weak that it simply does not have time to recharge the phone when it is working. This applies to third-party universal chargers, so it is best to charge the phone with “native” devices.

It is possible that the problem may be in the battery itself. To check it, you need to find the same one and try to charge the phone with it. If it works, then the problem is clearly in the battery, which means it needs to be changed.

Which phones are at risk?

This problem is not uncommon. Many users have such situations. Cheap Chinese smartphones are more likely than others to work this way. However, on the forums you can find messages that Russian Explay phones are charged only when they are off, but this does not apply to the entire line of the manufacturer and not even all models. It just happens, and not only with cheap Chinese state employees, but also with expensive flagships.

The presence of viruses

When downloading programs, movies or music, we do not check sites for malware. This step is more difficult on a smartphone than on a computer. For this reason, you can easily “catch” the virus.

Malicious programs block the ability to charge the battery by running a script in the background that is not displayed in processes. When the gadget is turned on, it does not charge, it simply does not see the charger. The problem is solved when we disconnect the device. To get rid of viruses, download and install the antivirus on your smartphone or check it from your PC.

Running applications

Some applications consume large amounts of battery power. Their main problem is that they are poorly optimized for the operating system. Even if you disable these programs, they may continue to run in the background. This slows down the charging speed of the battery. Sometimes the battery won’t charge until you turn off your smartphone.

To fix the problem, open Task Manager and disable any apps that are running in the background. You can also download the helpful Advanced Task Manager utility. The software “kills” unnecessary processes, frees up the memory of the mobile device and extends the battery life.

Charger problem

One of the reasons why a smartphone only charges when it is turned off is a problem with the charger. In the power supply unit, the charger can physically “move away” or oxidize contacts. This will reduce the voltage that goes into the battery. When the phone is turned on, it consumes power. A defective charger cannot supply the correct amount of current and voltage, so the battery will not charge.

To fix this problem, try using a different power adapter and USB cable. If the smartphone is charging when it is turned on, then you need to replace the charger with a new one (here are the main tips for choosing a charger). By the way, sometimes it is enough to clean the contacts from dirt and dust.

iphone, charges, only, turned

The smartphone charges only when it is turned off. what to do?

Charger problem, software crashes and other reasons for improper charging of the smartphone.

The smartphone charges only when it is turned off. not the most common problem faced by owners of mobile devices. Let’s look at the most common problems and how to solve them.

Firmware failure

Chinese Android smartphones. Xiaomi, Huawei, Meizu. use their own shell. Users often have access to administrator rights. they can install third-party firmware on the gadget. Unofficial firmware developed by an inexperienced programmer may affect the operation of the device. For example, the phone will only charge when it is off. This problem appears due to the fact that the charger starts to conflict with the firmware.

There are several ways to solve the problem:

  • Roll back to the official firmware version that was installed by default.
  • Reset all smartphone settings to factory settings (performed in the gadget settings).

Controller problem

A controller is a device that is responsible for power management. It regulates the voltage and current levels and ensures that the battery does not burn out while charging. When the controller fails, the smartphone may stop charging while it is on. To determine and solve the problem, you need to take your smartphone to a service center. It is difficult to determine the problem on your own, since for this you need to disassemble the device.

Battery malfunction

The problem may be a defective smartphone battery. When the gadget is turned on, the battery is discharged several times faster. Even connecting the charger does not solve the problem. the phone does not charge or charges very slowly. The only way to charge the battery is to turn off the gadget.

You can find out the level of battery wear using our instructions or the AccuBattery app. Basic information about the battery is displayed in the main window of the utility. Also, using the software, you can determine which programs consume a large amount of battery charge. If there is a problem with the battery, the only way to fix the problem is to replace it.

The main causes of the malfunction

This behavior of a smartphone is definitely not the norm. If the phone is turned on, it stops responding to the connection of the charger, and charges only when it is off, there is a reason for that. It can be either hardware or software, or be associated with a breakdown of the cable or power supply.

  • OS malfunctions;
  • a large number of applications are running;
  • malicious software;
  • problems with the controller, battery failure;
  • malfunction of the USB connector or charger;
  • unsuitable charger;
  • insufficient voltage level for full charging.

To solve the problem, it is necessary to identify the cause that caused it. First of all, you need to remember what can be associated with the appearance of a malfunction, perhaps the breakdown was preceded by any events.

The phone charges only when it is turned off: causes of the problem and solutions

For smartphone owners who are not used to deliberately turning off devices to recharge them, a sudden refusal of the device to charge in a standard way turns into a lot of inconveniences.

At the same time, the problem also affects those who practice this method of charging, because when the user, against his own will, is deprived of the opportunity to charge the switched on device, we are talking about a malfunction that requires elimination. Owners of different devices, regardless of the model and price bracket, can face a nuisance, be it an iPhone or a budget Chinese smartphone. Consider why the phone can only charge when it is off and how to fix this problem.

Controller problem

Among the hardware reasons, most often we are talking about a controller malfunction. When an element fails, the smartphone often ceases to normally replenish the battery’s energy reserves and only charges when it is off. The controller (BMS-board) monitors the charging and discharging processes, maintains the battery in normal condition and protects against critical voltage deviations by disconnecting.

The key function of the cell is to protect against overcharging while charging the device, as well as against deep discharge, leading to loss of capacity. It will not be possible to diagnose a malfunction without the appropriate knowledge and skills, so you should not disassemble the device yourself, the best solution in this case would be to contact the service.

Charger problem

A common reason why an iPhone or Android smartphone only charges when it is off is a faulty or inappropriate charger. The contacts in the power supply unit could move away or oxidize, as a result of which the voltage supplied to the battery decreases, which causes a lack of energy to maintain the active operation of the device during the charging process with a faulty charger. To find out if this is so, you can use a different cable and power supply (if there is no alternative memory, you can check on a device that has no problems with charging).

The problem may also lie in the fact that a non-native charger is used, iPhone and many Android devices do not fit universal chargers, you need to use original chargers for them. Sometimes it’s a matter of clogged contacts, cleaning of which will restore the normal operation of the device.

As for the occurrence of this problem when charging via a USB connection from a computer or laptop, here the relationship with a lack of energy is obvious. Full charging requires 1.5-2 A, while only 0.5 A is needed through the USB port, so to replenish the battery capacity, the smartphone will have to be turned off.

Running applications

Another reason why the iPhone 6 and above or the Android device only charges when it is off is the load of resource-intensive applications. Any switched on mobile device consumes energy, and if, moreover, numerous programs are running on it, especially those that consume resources, including battery power, energy consumption increases significantly. Even when you exit the application, it can continue to run in the background, wasting power.

Powerful software or numerous running programs significantly slow down the charging speed, actually preventing the phone from charging while the device is turned on, since the energy consumption exceeds its supply. Obviously, when the smartphone is off and the software is not functioning, nothing prevents the device from charging normally.

You should clear the phone of unnecessary applications and reboot, as well as view running tasks and disable third-party programs running in the background. The Advanced Task Manager utility or other tools with the function of cleaning the device from unnecessary processes can help to cope with unwanted processes.

Battery malfunction

In some cases, the problem is the deterioration of the phone battery. The resource of modern lithium batteries used in smartphones is about 2-3 years; with active use, the battery life is reduced. It is not surprising if the battery of the same iPhone 5s, released already 7 years ago, or an old Android device, after years of use, has noticeably worn out and lost its original properties.

Battery malfunctions lead to the fact that when the phone is turned on, the battery runs out many times faster, and, even if you connect the charger, the charge does not come or goes too slowly, and normally the device charges only when it is off.

You can check the health of the battery without special devices, for this there is software for iOS and Android. In addition, Android has a built-in battery test tool called by entering the USSD command ### (item “Battery information”). The same information can be found using the Battery app, for iOS there is a good BatteryCare utility available in the App Store.

The presence of viruses

Another reason why the phone charges only when it is turned off may be viruses that have leaked onto the device, for example, along with files downloaded from unverified sources. Malicious software is able to block the ability to charge the battery. the script launched in the background is not visible in the processes and when the device is turned on, it cannot charge, because it does not see the memory. In this case, when the smartphone is turned off, charging is carried out. The phone can be checked for viruses through a computer or scanned and cured using specialized software.

In addition, some third-party programs that control the charging process may be the cause. So, for trickle charging (recharging the battery with a low current to compensate for self-discharge) or turning it off when connected to a PC, special utilities are used. If the matter is in such software, then you need to get rid of it in order to solve the problem.
