Battery control circuit malfunction. The USB cable does not charge. The phone does not charge from the computer via USB. Nokia 5230 battery control circuit malfunction, how to charge from a computer
Charging the “old” Nokia 6230i from USB
- Lumber room *
I have several old Nokias (Nokia 6230 and 6230i) living on my balcony. These phones are technically fully functional and therefore I would like to use them in my projects where communication such as sending and receiving SMS is required. There is quite a lot of material on working with phones on the Internet. In particular, I can point to a very good set of articles that describe in detail how to send and receive SMS in PDU mode here
PDU mode is a clever way to send and receive SMS not only in ASCII, but also, for example, in Cyrillic.
Nokias of the mentioned series (6230 and 6230i) have a USB interface, connect and work perfectly and reliably with a computer.
From an OS point of view, the phone looks like a modem connected to a virtual com port.
It would seem that everything is fine, but these Nokias do not charge the batteries. When connected to a USB port, the phone responds to the connection, but says “not charging” on the screen. After the battery is discharged, the phone turns off, despite the presence of power from the computer.
I researched the issue and found a solution on how to make a Nokia 6230, for example, connected to a USB port, work as a connected device and charge the battery.
Studying materials online on the design of Nokia's battery charging mechanism yielded the following. The phone itself only has part of the charging mechanism. The phone circuit contains a key that controls the supply of charging current to the battery, a mechanism for measuring the charging current, charging voltage and voltage on the battery. Nokia has two charging modes - in the documentation they are called “current” and “special”.
The standard Nokia charger is a charging current generator. The words “current generator” mean exactly that the charger is a device with a high output impedance and tries to provide a stable current to the load.
The combination of the charging subsystem in the phone and external charging provides full charging.
In the documentation we were able to find parameters for both charging modes.
The current mode is characterized by a relatively high open circuit voltage (9.3 volts) and a high charging current (300 - 950 mA). The phone turns on charging (more precisely, it does not turn off the battery) if the charging current is at least 300 mA at a voltage of at least 5.54 volts. If any parameter goes beyond the specified limits, the charging key will be closed and the message “not charging” will appear on the display.
The special mode is activated if the input voltage is in the range of 4.65 - 5.2 volts. If the input voltage is below 4.65 volts or in the range of 5.2 - 5.54 volts, the phone will consider the situation unacceptable and will not turn on charging.
For a special mode, the charging current must be at least 90 mA.
Nokia's documentation on charging modes mentions that a special mode is intended for charging from solar panels and other sources with a small and unstable output current.
Thus, to enable battery charging in Nokia, you must provide a voltage in the range of 4.65-5.2 volts and a current of at least 90 mA after turning on charging in a special mode, or a voltage of more than 5.2 volts and a current of about 300 mA in current mode.
An experiment with a Nokia 6230i and a laboratory power supply showed that charging does not turn on if the voltage is less than 5.3 volts. It was not possible to get the phone into special charging mode.
The standard USB port has a voltage lower than the required 5.3 volts and therefore the phone does not turn on the charging mode.
To increase the voltage, I decided to use a ready-made Step-up converter board. A search on dieextrim-ebay gave me the LM2577 Adjustable Step-up Power Converter Module DC-DC board, which is a step-up converter. The board can operate with an input voltage from 3 to 30 volts and produce an output voltage from 4 to 35 volts with a maximum current of up to 3 A. When the converted power is more than 15 watts, a radiator is needed. I bought such a board for 71 rubles with delivery (end of 2013). Surprisingly, the board arrived quite quickly and turned out to be fully functional. Here she is:
I set the board's output voltage to 5.4 volts. The experiment showed that the phone in this mode turns on charging from time to time. The battery is fully charged all the time, or rather the indicator on the screen shows full charge. After a couple of months of working in this mode, I let the phone discharge before turning off - 2 days. For a battery about 9 years old - an excellent result :)
In theory, charging should begin when voltage is applied and a little more than 5 volts, however, at a voltage of up to 5.3 - 5.4 volts, my phone wrote “not charging.” This may be due to the fact that I had documentation for a newer phone. I was unable to find documents describing charging conditions specifically for the Nokia 6230i.
When I was looking into connecting the phone, I did not have a Nokia-specific connector. I considered it unreasonable to buy a cable for 800-900 rubles and soldered the wires directly to the connector and protected the soldering area with hot glue:
As usual, literally a week later in one of the Moscow Auchan stores, I accidentally came across the required cable for an insignificant 50 rubles. I bought this cable and may use it for the next craft with Nokia, fortunately I still have several of them.
The POP port pinout is shown in the figure below:
The connector contacts are counted from left to right if the phone is positioned with the screen facing up and the connector facing you:
The first and second contacts are located to the left and right of the round charging connector, and they carry charging current.
Pins 5-8 are connected to the USB plug (+5 V, D+, D-, GND), respectively.
Contacts 3 and 4 can be connected to each other, so the phone detects the connection of the accessory, which it writes about on the screen. You don’t have to do anything with these contacts; this does not affect the phone’s operation as a modem or charging.
USB power (usually the red wire) is also supplied to the converter input. The increased voltage from the converter is supplied to the first pin of the POP connector.

Sometimes it becomes necessary to charge Nokia phones or smartphones that are equipped with USB connectors from a computer. If you are the owner of such a phone, charging it is no longer a problem, because... it can even be powered from a portable device.
You will need
- - smartphone or Nokia phone with a USB connector;
- - PC or laptop;
- - connection cable.
Instructions
In this article, we will look at the main reasons why the phone does not charge via a charger, USB or computer, and also provide instructions on how to fix it.
There are several reasons:
- A glitch in the phone's operating system.
- Charger fault.
- Battery control circuit malfunction.
- Physical damage to the charging socket.
Now we will analyze the algorithms of actions for each of them.
Who couldn't discharge the battery and charge their smartphone at the airport, cafe or public transport? The problem is larger than usual, but is this the most appropriate solution? Some experts say there are many dangers, so it's best to take precautions.
According to computer security firm Kaspersky Lab, cell phones leave a huge amount of data exposed when they are connected to computers during a process known as a “handshake.” In this data exchange, the phone transmits information through the computer via the computer. And it "tells" the machine what it is called, what its manufacturer is and its serial number, what its operating system is and down to its list of files.
Glitch in the smartphone operating system
This is the easiest problem to fix. In fact, in this case, the battery is charging, the system just doesn’t see it, that is, the charge percentages are not added to the screen. This could be caused either by disabling the battery indicator in the settings, or by a glitch in the system. In the case of a glitch, just restart your smartphone on Android or iOS.
Juicer: File Stealing
This is called a “load vulnerability” and professional hackers can hide. Some of these viruses camouflage themselves from official pages by overlaying windows to obtain personal and banking information from fraudulent emails. And this is just an example of “juicing.”
Research journalist Brian Krebs, who specializes in cybercrime and digital security, explains in a blog post that there are the same risks at free refill points for public kiosks. "Some people can handle almost any risk to charge their cell phone battery," says Krebs.
Sometimes the problem may be that the charging indicator is displayed incorrectly and the phone turns off, although it shows that the battery is 100% charged, or it is not fully charged. This can be solved with the help of, or, if calibration did not help immediately, then by flashing and then calibrating the battery.
The phone does not charge from the charger or USB
This problem will require you to spend more time diagnosing and money to solve, but it should not cause any special problems. In this case, the malfunction may be either a breakdown of the charging power supply itself, or a broken cable. You can check the functionality of the charger by taking a voltmeter and measuring the voltage at the output connector. If there is no voltage, then the charger will have to be changed, although in the case of a USB adapter, you can try changing only the cable first. It is best to buy branded chargers, but if for some reason this is not possible, then you should carefully compare the performance characteristics of the new charger with the performance characteristics of the old one and check its performance immediately upon purchase.
Use your mobile phone's encryption and authentication features to protect your data and files. You will find them among the security settings. Do not charge your mobile phone using computers or charging points that you do not trust. If you risk downloading it to a less trusted site, don't unlock it while charging.
Protect your phone with a good password. The most effective measures to achieve longer battery life in cell phones and tablets, tips to prevent wear and tear on lithium batteries. Modern mobile phones or smartphones with an Internet connection, despite the presence of fairly efficient lithium batteries, are excellent consumers of energy. When using them with their default configuration, we will check that the battery power is consumed quickly, sometimes this can only last a few hours.
Battery control circuit malfunction
Modern batteries have their own control and protection circuit, and sometimes the problem may lie precisely there. Typically, problems with it are accompanied by a sudden shutdown of the device without the subsequent ability to turn it on. In this case, all that remains is to replace the battery.

Recalibrate your cell phone battery
If the power light comes on, start the device and make sure it is charging. Battery charge does not increase while charging. The battery is not charging fully or is charging slowly. Try a different outlet.Physical damage to the charging socket
You cannot fix this problem on your own; it requires contacting a service center, so we will not consider it in detail.
Afterword
And so we see that in most cases this kind of problem can be solved on your own and without special expenses, with the exception of cases of physical damage to the charging socket or when the battery is non-removable. In these cases, the problem can only be solved by contacting a service center.
If your device works well in Safe Mode, the problem may be caused by . The worst thing is what happened to us when we needed it the most, such as while waiting for an important call, message or email, etc. No, in fact it can be dangerous.
Before we address the problem of hackers, it's important to note that not all sources of electricity are necessarily good for your phone. There are a lot of complaints online, mostly from users trying to boot up their latest phone by connecting them to adapters or used chargers. In some cases, phones have become unusable. In some even stranger cases, people using their phones during services have been seriously injured or even killed.
Why your phone won't charge: what to do Author DimkaVarlamov average rating 3.5 /5 - 2 user ratings
Actually, this problem is very rare. As soon as you connect your smartphone/phone to the USB port of your computer or laptop, it immediately begins to charge automatically. This is, so to speak, the norm. Even if you connect the device to the USB port of the TV, the smartphone will start charging in the same way. Yes, not as fast as from the network, but it will charge. Still, some users complain that when they plug in the device, it doesn't even start charging. What's the matter?
Unfortunately, these are more than just accidents. We doubt you want to test your phone's durability this way. On average, a phone's file and folder host system requires over one hundred kilobytes of data. To give you an idea, this is the size of a copy of the Alice in Wonderland eBook.
Locking your phone would save you from this risk, but honestly, would you want to be without your phone while it answers? The size of this data depends on the mobile platform and host operating system. But in any case, this is more than just a “charge”. As we found out, this data includes the mobile phone name, vendor name and serial number.
If we were talking about tablets, answering the question would be much easier: this is due to the fact that some tablet models do not initially support USB charging. The reason is simple: they waste more energy than they receive from the USB port of a computer or laptop. This applies to large tablets; with much smaller smartphones there are no such restrictions, and therefore we need to look for the reason.
You must be thinking that you can't see where the problem is, there is only one, as we found that we were looking for information available to the public that a particular provider allows much more than what is stated in the system. The latter were developed several decades ago to provide communication between modems and computers.
These commands allow you to call any number at your own expense, of course. And if you're roaming, such unexpected calls can quickly add up. Depending on the provider, roaming mode can make it easier for a hacker to install any type of application, including malicious ones.
Restarting the device
This is the first thing you should do when dealing with this type of problem. If there is a failure in the smartphone software, a reboot is what allows you to deal with it in most cases.
Reboot the gadget, reconnect it to the USB port and see if charging has started.
Everything you just mentioned is possible even if your smartphone is locked! It is a system that collects data from devices to which it is connected for some reason. This is a shaky power source, such as a powerful capacitor or a computer, that installs a backdoor on your device. The one thing you ignore until you turn it on.
Using the fast charge feature
Note. This type of charger is easily identified by the presence of this reference on the charger itself. You can use the accessories that best suit your needs!
Connect your mobile device to a Adaptive Fast Charge or Fast Charge 0 compatible device.
Cable inspection
It would seem that what could happen to a USB cable? It looks like new... Yes, most often the USB cable really looks like new or at least is in excellent condition, but this does not mean that it is functioning normally. It is enough just to squeeze it once, for example, with a chair leg, so that it stops working.
Increase your download speed
If you try to recharge the battery using a standard charger, you will not be able to use the fast charge feature. The battery is charging, but the battery charging time will be normal. Turn off your device's display to increase charging speed. You can check the remaining time by looking at your smartphone screen. Battery charging time may vary depending on your own charging conditions.
If your phone overheats while charging, or if the temperature of the room it is in increases significantly, charging speed will decrease. These are normal operating conditions to prevent damage to the battery and your smartphone.
By the way, this is easy to check. Connect the USB cable with your phone to the wall charger and see if the device charges. If so, it's definitely not the cable.
By the way, even if the cable is working, but you have another one, try using it.
Is charging my smartphone all night bad for the battery?
If this is not the case, it will negatively affect the charging speed of the battery and will significantly increase the charging time. The fast charging function is sensitive to the equipment used: a partially damaged cable is enough to prevent the fast charging function from working. This security system is designed to protect your device, but also from you. Let your device charge for about 10 minutes and the fast charging feature should activate on its own.
Cleaning the contacts of the microUSB connector
Pay attention to the microUSB port on the smartphone itself. Perhaps dust has accumulated in it and the contacts need to be cleaned - they are the problem.
In a good way, it is better to clean the contacts with an eraser, but it simply cannot fit into such a small hole, so you can use a toothpick or a match with cotton wool. And be extremely careful - one awkward movement and the microUSB port will be disabled. In this case, the phone will not charge at all.
Sometimes restarting the device can speed up the process. The fast charging feature is so sensitive that it is susceptible to faulty electrical installation. It's possible that the current socket is working, but a small connection issue could cause the socket to fail 100% and prevent the fast charge feature from working. Your device will charge at a slow rate and you will increase battery wear! Unfortunately, the fight against counterfeiting comes down to fighting a hydra: when we close an online store, the seller opens a new one under a new name within one hour!
Using other USB ports
Be sure to use a different USB port if available. It is possible that the current USB port is not receiving power, or there is not enough current, or it has completely failed.
Lack of charging current
If there is not enough current, the smartphone will not charge from the USB port. However, like other devices.
How is cable so dangerous?
A real cable chaos because it is difficult for the consumer to know what he is buying and often, especially on cables of this type, tends to save a few euros. Creating power delivery profiles has become necessary to allow older devices and new devices with different needs to be used simultaneously with the same chargers.
To work in the latter mode, given the risk of "frying" the device, the cable must be active and with two processors that exchange the charging modes accepted by both, deciding that it is best to reboot the device quickly.
Because the reversible cable is used by two.
A choice that gives an advantage: the device therefore believes that it is connected to a charger that can deliver 3 amps and requires the amount of energy to be very fast.
Why is there a lack of current? The reasons may be different: lack of energy in the USB port, which is located on the front panel - a common problem, you need to use the port that is located on the rear wall of the system unit; low-power motherboard circuits; component settings, etc.
Installing the application on your computer
The power indicator turns red while charging and turns off when the camera is fully charged. Download the app that matches your computer. Double-click the downloaded file and install it according to the on-screen instructions. When a screen like this is shown below, the installation is complete.
Checking and editing camera settings
Launch the application installed on your smartphone. It's not a cheap name for the horror, and the fact is that you need a better cable to carry more electricity, and cheap wires are often not good. Charging cables also cannot be too long, because the longer the cable, the greater its resistance, the more difficult it is to provide the correct current and maintain voltage drop.
microUSB port does not work
In this case we are talking about the microUSB port of the smartphone. If it fails, then the device does not charge at all and there is only one way out - to change the part.
What to do if nothing helps?
First, try connecting your smartphone to another computer or laptop to a USB port. If it still doesn’t charge, the problem is probably in the device itself, but only a specialist can find out the real reason.
But I wanted to expand it a little.
Those who have a Nokia 5800 Express Music smartphone or similar models (Nokia 5230) know that you cannot charge your phone using a Data cable. Therefore, you either have to constantly carry a charger with you, or buy an additional external battery, or risk being left without communication at the most inopportune moment.
My wife has a Nokia 5800 smartphone, so the issues of powering the smartphone fell on my shoulders :).
Of course, an external battery is good, but in my wife’s small purse this gadget takes up quite a lot of space and adds unnecessary weight to her. And, as a result, she carries it around infrequently, only when there is a chance of being left with an empty battery away from home (where there are no outlets).
Once, while walking through a Chinese website in search of a film for a smartphone, I accidentally came across a cable that has a USB connector on one side and a standard Nokia power connector on the other. Having looked at the characteristics of the Nokia charger, I saw an output voltage of 5V (the same voltage is in the USB port). Since the price seemed low, it was decided to buy this cable.
Dealextreme, as always, broke the package, so this cable came completely alone in its own personal package. The cable was packed in cellophane:
Here's a closer photo of him: 
Here is a photo along with the original charger: 
It immediately caught my eye that the Nokia connector was slightly larger on the purchased device. Here's a photo for comparison: 
Tests:
First, insert the standard charger. Almost the entire connector fits into a smartphone: 
Now we connect the purchased cable. We immediately notice that it couldn’t fit into the smartphone entirely; it doesn’t fit a couple of millimeters. 
We connect the cable to the USB port of the computer and... lo and behold, the smartphone accepts the charge! 
Pros: what advantages could a simple cable have... it just gets the job done. I also forgot - a very small price.
Minuses: long connector for smartphone.
Conclusions: definitely take it!!!
Did you know that Nokia developed the Nokia 5230 under austerity conditions? No? Do you think that the price of the device has nothing to do with savings on production? So marketers know their stuff!
So what do we have? On our table is a Nokia 5230 with 848 series firmware. The firmware is buggy. Instructions have been issued for service centers (official, authorized), according to which, before trying to repair anything (even if the buttons stick), you need to update the firmware.
