4s does not charge when turned on. iPhone only charges when turned off

Youtube

Smartphones have become life companions; not a single task can be solved without the help of these electronic assistants. Calls, internet, useful applications, everything is on them. Sometimes it happens that time battery life devices begins to decline rapidly. Turning from 20 hours to 9, then to 3, and finally, the iPhone charges only when it is turned off. Why this happens and what to do to return the device to combat readiness, we will tell you in this article. Let's start with the methods that you can do yourself at home; if that doesn't help, then a master from the nearest service center will help.

How can you determine whether your iPhone is charging when it is turned off? This is easy to do; if you see a picture like this, it means energy is reaching the device board, but it does not mean that the battery is being charged.

If you see a picture like this, most likely there is something wrong with the charger, cable or lightning connector.

Below we will look at what steps to take and how to revive the gadget at minimal cost. Let's get started.

Checking the memory

To begin with, if the iPhone charges only up to 4-20 percent when turned off, you should check the charger on another device. It is quite possible that:

The wiring in the cable is interrupted - the current strength in this case is significantly reduced, preventing the battery from being charged to the required 100%.
The electronics in the charger unit have burned out, again, the current strength will be significantly reduced. Repair is powerless here; it’s better to immediately buy a new charger for iPhone 6.
The lightning plug is loose or the chip on the cable is damaged (yes, yes, there are chips in iPhone laces).

It’s quite simple to check whether the charger is working; we take a working charger from friends/neighbors/lovers and connect it to our unfortunate device. The iPhone beeped joyfully, notifying that energy had entered the battery, then we run to get a new, preferably original, charger.

You can also buy Chinese ones, but not the cheapest ones; chances are you will end up with quality products. But it remains large percentage that you will get a counterfeit product that costs a lot of money and is not capable of fully charging the gadget’s battery. Among other things, counterfeits can damage the device’s power controller, and this is 100% dependent on the services of service centers.

Cleaning the connector

You can try cleaning the connector; it often causes the iPhone to boot up and only work when charging. To do this, take an ordinary cotton swab and carefully, without fanaticism, clean the connection point of the lightning plug.

Inspecting the cable

Now let's take a closer look at the cable itself. There should be no creases or kinks on it; if there are any, we try to change the wire, borrowing it from a neighbor. in 80% of cases it is the culprit, if so, feel free to throw the cord in the trash, repair is not advisable, even if it is an original accessory that came with the phone.

The screen says "accessory is not supported or certified"

Try reconnecting the cord with the other side, sometimes it works.
The wire is broken or broken.
You neglected the advice to clean the connector.
Yours is cheap Chinese fake, throw it away and go to the store again.

Close and delete applications

After several years of work for the benefit of the user, the smartphone battery may no longer provide the required amount of energy. Then a situation arises: iPhone 5, 5s, 6, 6 plus can only be charged when turned off. Before opening the case of the device, let's try to turn it on while charging, even if the iPhone does not charge when turned on. In this mode, we will close and remove “energy eaters” - applications that consume energy in background. Let's reboot the device and see the reaction.

If it helps, great, you’ll have to replace the battery; if it doesn’t help, no problem, read on in the article. But in any case, you end up with, at a minimum, a replacement battery, at worst, a replacement of the power controller and everything that will require a repairman to replace it.

Reset iPhone to factory settings and update iOS

This measure will allow you to restore functionality in 20% of cases, most likely the problem is something else, but as a measure before replacing the battery, it’s worth trying, at least make sure 100% that this is the problem.

How to properly reset to factory settings, read in this article; how to update, read here.

Why can my iPhone only charge when it's turned off? This question remains to be asked to the moderating battery; this will be the final and saddest part of the article. Sad because you will have to leave the house and spend money on smartphone repair specialists.

We reanimate the battery

Battery problems are familiar to all owners. cell phones, iOS or Android, it doesn't matter. Over time, the battery material begins to “deteriorate”; the more charge-discharge cycles, the less the electrical capacity becomes and the faster the smartphone runs out. Usually the “death” of the battery occurs after 3-4 years of operation, the number of cycles exceeds 500-700 and problems begin. One of them is that the iPhone can only charge when turned off. Now, in order, what is worth checking and where to put your hands.

Having checked the charger and the accessories adjacent to it, perhaps even replacing them with new ones, removing everything that was not required applications and generally turning off the smartphone, but still, the iPhone charges only when it is turned off, then we move on to a more complex stage.

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

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

Non-removable resuscitation iPhone batteries It is advisable to practice not at home, but even better, it will be left to be torn to pieces by experienced people who know a lot about safety and quality repairs mobile phones.

Conclusion

To summarize, I can say that if the first sections of this article did not help you, then you will not be able to independently find the answer to the question of why the iPhone charges only when it is turned off. I recommend contacting service center, where they can help revive an electronic friend for the right amount of money. Your intervention will most likely lead to an increase in the cost of repairs. Be careful and attentive, and everything will work out.

How the repair works:

1 We diagnose the imported goods for free
device received by you or our courier.
2 We carry out repairs and also provide a guarantee on new installed parts. On average, repairs last 20-30 minutes.
3 You receive a working device yourself or call our courier.

Possible reasons why this happened:

The charging device itself has broken down;
The device's power controller has failed;
A foreign object has entered the charging connector;
Program failure;
Other hardware problems.

Why does the iPhone only charge when turned off?

The reasons why the 6 and 6 Plus do not charge can be trivial - a faulty socket or the charger itself. In this case, you need to use a different power source and charge the Apple. Also, the reason for inoperability may be that the period for charging is too short. The phone must be charged from the outlet for at least twenty minutes; from the adapter - half an hour.

When such measures do not help, it is worth showing the device to specialists to determine the cause and further repair, if required.

iPhone 6 only charges when turned off

If there is a problem where the iPhone does not show the charge level and is generally turned off, the culprit may be software glitch. What to do: try to solve the problem by rebooting the gadget.

To perform this manipulation, you must simultaneously hold down the Home and Power keys for fifteen seconds. If this does not help, you need to try by holding down the “Home” and “Power” keys for 30 seconds to put the smartphone into recovery mode. If these measures do not help, you must contact the service center.

iPhone only charges when turned on

Another problem is a broken connector. Inspect it carefully to see if a foreign object has gotten into it or has been damaged. If you have such suspicions, do not try to do anything, as this may lead to deformations and the appearance of additional microscopic cracks.

With this problem, you need to contact a repair specialist to replace the connector. It is also not uncommon for other problems with the iPhone to result in the phone not responding when turned on. For example, it falls on the floor or gets wet. You should not try to solve the repair issue yourself; it is better to immediately seek help from qualified specialists in repairing this equipment.

In some cases, the reason for the slow charging of the 6 and 6+ when it is turned on may be a problem with the battery. Here it will be necessary to replace the battery, but only diagnostics of the device itself can always help determine the exact cause.

We serve employees of these companies

Over the past decade Cell phones(smartphones) have penetrated into all spheres of human activity. Many people simply cannot imagine leaving home without a faithful assistant in their pocket.

Increased functionality electronic devices entails increased battery consumption. And it is with this block that phone owners most often have problems.

note

A problem with charging a battery can be caused by many reasons: a malfunction of the battery itself, a broken USB port, or a failure of the electronic circuit responsible for charge control.

There are also known gadgets One problem: the battery is replenished only when the device's power is completely turned off.

So why does the iPhone only charge when it's turned off? It is difficult to answer this question right away; there may be several reasons. Below in the article are possible options solving the problem. In some cases, the user can cope with the situation on his own, in others, he will have to contact a service center for help.

Charger fault

The most common reason for an incorrect iPhone charging algorithm is a malfunction of the gadget’s power adapter itself. To verify this, you need to take a similar adapter from a friend or work colleague and connect it to your device. If the process of replenishing energy starts even when the device is turned on, then it’s all about the charger. If the situation does not change, you will have to contact a specialist: most likely, the charge controller has failed.

You can also try connecting your charger to another, known-good Apple smartphone. If the charging process has started, then you need to look for a problem in the device itself.

Battery malfunction

The second reason why the iPhone only charges when it is turned off may be a battery malfunction. The battery often stops working properly due to normal physical wear and tear. In such a situation, you should do the following:

It is important to know

If this procedure did not solve the problem, may have malfunctioned electronic circuit power controller and you will have to take the device to a service center to restore functionality.

Problem with the software part of the mobile device

Sometimes the behavior of the iPhone described above when charging is possible due to incorrect functioning of the software part of the smartphone. For example, the power consumption of running applications exceeds the charging current provided by the power adapter. If this situation arises, you need to clear the device memory as much as possible from unnecessary applications and then test the device for charging again.

Additional solutions to the problem:

If the iPhone charges only when it is turned off and does not respond to charging when it is turned on, do not rush to change the smartphone battery or buy a charger. First, try to find out the cause of the breakdown and fix it yourself. When the iPhone does not charge or the charging level increases too slowly, of course, the cause may be a broken cable, but similar malfunctions can occur under other circumstances.

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. Most often they appear when charging the iPhone.

The most common battery charging problems are:

iPhone only charges when turned off
iPhone charges very slowly when not turned on (off mode) or on state
The status “Not charging” appears on the display
the charging percentage does not exceed a certain value, n
I get the error “Cable is not certified”

Problems associated with the iPhone not charging well can be varied. You can determine the malfunction yourself by following certain steps.

Main causes of malfunction

When an iPhone does not charge well or discharges very quickly, many owners begin to look for the cause. faulty battery smartphone or cable. However, you may have completely serviceable original components; do not rush to change them.

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

software failure
dust and other small particles entering the device
faulty USB port
using a non-original cable, battery
insufficient voltage in the electrical network

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

What to do if there is no battery charge

If at iPhone connection To working unit power supply or USB connector, the device does not charge, there can be many reasons.

Try to troubleshoot the problem in the following ways:

turn off and reconnect your iPhone to a power source
If the iPhone is completely discharged, leave it turned off and charging for about half an hour
charge your smartphone from another outlet or USB port

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

What to do if the battery is charging slowly

At first, the new device charges quite quickly. 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 start by using a larger power adapter or try the following methods:

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

If you carry an iPhone without protective cover in your pants pocket or purse, try cleaning the connector from dirt and dust. This can be done using a regular toothpick. However, be careful when performing mechanical actions so as not to damage Lightning.

What to do if the status is “No charging”

When charging smartphones and other Apple technology, in the right top corner you can see the charging indicator. If during the process of charging the gadget you find that there is no power being supplied, a source of greater power is required.

To avoid similar problems, you must adhere to certain rules:

Charge your gadget only with original power adapters manufactured by by Apple and included with the smartphone
If the device does not charge when you plug the cable into the computer connector, use power sources with higher power
do not charge your smartphone with external USB adapters from third-party manufacturers

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

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

iPhones latest models are able to recognize genuine USB cables, because the manufacturer has begun installing a special chip in the plug. However, today you can take the risk of purchasing, so to speak, a “chipped” charger made by the Chinese. But a fake will not be able to provide the proper speed for recharging the battery and can lead to serious damage.

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

turn the cable off and on again
if the problem persists, use a charging cable that you are sure is original
try updating software(there may have been a glitch)
reboot your smartphone

Using non-original cable, don’t be surprised if you see the phrase “ this cable or the accessory is not certified.” The manufacturer quickly determines what type of cable is used and removes the warranty if a Chinese counterfeit is used.

How to restore charging function if components are faulty

Sometimes Apple smartphones are not charging because the internal components of the device are faulty.

Lack of charging may be due to a breakdown of the following gadget elements:

battery
power controller
connector for charging the device

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

iPhone owners often encounter various difficulties when trying to charge the battery. The most common problems are the absence of a charge indication, the battery’s inability to charge, and the inability to connect the plug to the socket. But sometimes a very specific problem appears in which the iPhone charges only when it is turned off. Our article will tell you why this happens and how to deal with such a nuisance if it happened to your smartphone. But first, we note that there are several sources of this problem, and in some cases the user can solve them independently, without resorting to the help of a repair shop.

Oddly enough, if the iPhone only charges when it is turned off, then the accessories, or more precisely, their malfunctions, may be to blame for the problem. Does your device charge only when turned off? Maybe the charger itself has failed - this happens quite often. To find out if this is the source of the problem, you just need to try charging the gadget with another device. If the process goes well, you need to turn on the device, and if after that everything remains the same, it means that the problem was a malfunction of the previous charging.

And if the process has not started, most likely there are serious damage inside the iPhone 4S (or any other phone model), for example, the charge controller often breaks down. In such a situation, only specialists can help. The gadget will need to be taken for repair, where a technician will open the case and replace the failed part with a new one. Doing this yourself, especially in the absence of any experience, is highly discouraged, since all the parts inside the case are very fragile. In addition, you need to know the algorithm for assembling and disassembling the device so that every part always remains in its place.

One more method should be mentioned, which will allow us to draw a preliminary conclusion that the source of the problem is, after all, the iPhone itself. You need to connect the gadget to another Apple phone, and if the first one starts charging, then it’s the problem.

Having decided to buy new charger for iPhone 4S or another version of the gadget, make sure that it is an original accessory. If you use compatible devices. The warranty for repairing the device will most likely be lost. In addition, it is often the use of such charges that causes breakdowns. Of course, such accessories are much cheaper. But is it worth the risk of later overpaying for smartphone repairs that could have been avoided?

As the practical experience of many owners of Apple phones has shown, non-original accessories often cause various breakdowns of the phone. In particular, batteries and charge control circuits fail.

Checking the battery and installed software

The problem of charging the iPhone only when it is turned off may be due to the battery itself, which loses its quality after prolonged use. And the only solution in this case is to leave the device charging overnight. Perhaps by morning the battery will at least partially restore its functionality. But this, of course, will be a temporary solution to the situation, and not a solution to the problem. Sooner or later the battery will have to be replaced.

If your iPhone only charges when turned off, there may be a reason large quantity software that causes increased energy consumption, exceeding the charging current. Because of this, the charging process cannot proceed normally when the device is turned on, and when turned off, nothing prevents the battery from charging. To fix this problem, the user should delete rarely used programs from the smartphone memory, and then conduct a performance test charger again.

1 Reset the system settings to factory settings. Sometimes this can help restore all functions of the device. 2 Update all programs, which often leads to the iPhone starting to work normally. 3 Carefully inspect the charger cable - it may be damaged. 4 Test charging using a computer to determine the malfunction of the phone itself and its internal components, if any took place.

But if none of the advice helps, it is better to return the iPhone, which is under warranty, back to the store where it was purchased or exchange it for a new one. And if the warranty period has already expired, you need to contact an authorized repair shop.
Now you know why the iPhone only charges when it is turned off, and what to do in such situations. And then we’ll look at the rules for properly charging Apple devices.

Rules for properly charging an iPhone

To ensure that the charging of your Apple gadget never fails, you need to know and follow certain rules for recharging the device. By the way, this is so important that a separate page is dedicated to this issue on the manufacturer’s website on the Internet.

So these rules are as follows:

1 You cannot charge the battery in extreme temperature conditions, specifically when the thermometer drops below -40 or rises above +50 degrees Celsius 2 Use only the original accessory (at least a certified USB cord). Why is this so important? Let’s look at specific example. If the charge voltage of a lithium-ion battery is increased by only 4-5%, then it will begin to lose capacity 2 times faster with each cycle. To avoid this, in network adapter from the manufacturer, a PMIC controller was built directly into the phone itself, which controls the charging factors and does not allow the values to go beyond acceptable limits. It's about about the values of temperature, voltage and current. 3 Never allow complete discharge gadget batteries (up to 0%). 4 Do not charge the device to 100%. 5 Once a month you need to discharge your gadget to 100%.

The most optimal temperature range, according to Apple, is 16-22 degrees, and the risky value is above + 35 degrees, at which it is highly not recommended to charge the gadget. Overheating of the case has a strong Negative influence on the battery, quickly reducing its life and leading to rapid breakdown.

But, of course, no one thought of taking these tips literally and walking around with a thermometer in their hands all the time. It is enough to avoid direct contact sunlight on the device, do not leave the phone in the car in hot weather and do not put it under the pillow to recharge. Following these simple rules will help you increase the life of your battery.

In Chinese adapters (so-called “nonames”), such a controller is not always present. In this regard, the output voltage can be very high and will burn out the power controller, and then completely destroy the battery.

Therefore, the advice here is very simple - always use only original accessories.

If the user often does this, the battery life will be depleted much faster. The fact is that battery operation is based on cycles (1 cycle = complete consumption of 100% battery capacity), and every time the owner of an iPhone completely discharges it, he accelerates the “death” of the battery.

This action does not greatly affect the life of the battery, but, nevertheless, it is highly undesirable. Of course, the built-in controller, which was mentioned above, will prevent the device from overheating. But the battery life of the gadget will be significantly reduced.

Users advise leaving the device to charge overnight. With this approach to the process, the battery will be charged for at least a day at active work user, without additional charging, for 2 years.

It is difficult to describe the chemical reactions that occur in an iPhone battery; we will only note that the battery ages over time, which is manifested in a decrease in its capacity. Battery failure is also caused by non-compliance with the smartphone user's operating instructions. And over time, all this leads to the fact that the controller loses the ability to accurately determine the battery charge level, and, as a result, the device turns off even when the charge level is 1% or more.

To calibrate the controller and bring the battery indicator back to normal, you need to completely discharge the phone. But to do this Apple council it is necessary no more than once every 30 days.

In conclusion, we note that each iPhone user usually approaches the process of charging their device in their own way. A single scheme cannot suit everyone, since everyone has their own rhythm of life and the like. Please remember that the battery will age. Even if you don’t use the gadget at all. But it’s still worthwhile to at least slightly (not strictly) adhere to the above rules developed by the manufacturer itself in order to maximize the “life” of your smartphone’s battery.
