Can I turn on my phone without a battery? There is an opinion that for this it is enough to put it on charge, after which you can turn it on, but this is not so. A conventional charging device involves working with a rechargeable battery, where it first stores and then releases current. It is not possible to power the device directly from charging: since the current is too low, the voltage will immediately drop to zero as soon as you try to "wake up" your phone.

To start the device, you need to make yourself or buy a stabilizing power supply that generates a constant voltage of 3.7V with a maximum current load of not more than 2 A. The required voltage should in no case be higher than the permissible value, even at the moments of switching on / off and drops load. Please note that the power supply is protected against overvoltage in the event of a malfunction, and also has preventive measures in the event of a short circuit. How to turn on the phone without battery?

Instructions for turning on the phone without battery:

1. Turn off the phone, and, disconnecting it from the charger, remove the battery.
2. Using a voltmeter, find two contacts on it that would correspond to a voltage of 3.2 to 3.7 V. Determine the effective polarity of the contacts.
3. Apply the correct voltage from the uninterruptible power supply system to the appropriate contacts in the battery compartment. You can solder the ends in case the phone will not be used in another way (in this case, the power supply must be disconnected from the power supply).
4. Turn on the power first and then start the phone.
5. You can check the serviceability of the resulting system as follows: connect the phone to the security system using a USB cable, so that the common wire of the circuit is disconnected from the power supply.

It is important to remember that in the event of a power outage or disconnection of the contact, the phone will instantly turn off. If the device is part of a security alarm, care should be taken that it is equipped with an uninterruptible power supply unit, which must be reliably protected from temperature fluctuations.

Tip: instead of a power supply, you can make an adjustable stabilizer, and draw the voltage, for example, from a computer. Many old phone models (namely, these are most often used for auto-dialing for security purposes), request an additional connection of a resistor, and some devices with four-pin batteries may need two resistors each.

Some models are equipped with a system for reading information from a chip, which is built into the battery. For example, power from a Siemens battery is removed at the extreme terminals. Between them are information contacts that allow the phone to identify the battery: NiMH or LiIon. These contacts are connected, as a rule, before the last terminal to "minus" through 20 kOhm. Such a resistor acts as a thermal sensor during battery startup and is located inside the battery.

To connect it you need:

• make a "model" of a battery with pads for contacts or use a case from a similar battery;
• solder contacts on the pads with resistance similar to that required in the battery;
• then the wires from the power supply are soldered, the main thing is not to mix up the polarity.

As you can see, the phone can be turned on without a battery, for this you only need some tools and knowledge from this article.

IMPORTANT: Enable cellular telephone without a battery it will not be as easy as it seems at first glance. 4. Let's try to turn on the mobile phone after connecting the power supply. In order to turn on a mobile phone without a battery today, several basic methods of connecting certain systems will be required. 2. Turn off the mobile phone, disconnect the charger supplied with it, then remove the battery.

Question: is it possible to turn on the mobile without a battery - using external power sources? The answer is yes, and everything works! It was necessary, in due time, to make security (eavesdropping) systems with dial-up on a mobile phone. For this, old mobile phones with dead batteries were used. For such work, a STABILIZED power supply was made, for the battery voltage and connected to the battery terminals.

This resistor (or two resistors) is placed inside the battery and is a temperature sensor when the battery is being charged (using a thermistor). Moreover, some phone models, by the resistance of these resistors, determine which battery is connected - Ni-MH or Li-ion. For those purposes, in order to figure out how to turn on the phone without a battery, you can talk about very interesting topics. By the way, today the m-tarif.ru help portal offers very beneficial material for each reader and visitor, which will be very useful for solving the problem of working with a mobile phone, which must be turned on even when it is virtually impossible: for example, without a battery battery.

Let's check the functioning of the mounted system. Connect the phone and the security device with a USB port. The standard charger supplied with a mobile phone is designed to work only with its battery, capable of delivering high current in a short period of time.

There is a mobile Nokia N97 injured after a fall and subsequent kicking on the asphalt. Ahead of the questions, I will answer immediately. the phone took part in a street fight and therefore feels so bad). Who has what options? This article is about how to turn on a phone that always reboots (i.e. does not turn on) and you know what the problem is. This happens, for example, because of everyone's favorite FontRouter program (played around with the settings and the phone did not turn on).

In addition, many phones also require the connection of a resistor (and for 4-contact batteries - two resistors), between the common and the third (fourth) terminal. In general, every reader of the portal can ask such a problem, since sometimes the batteries are either not there for one reason or another, or they are used up, and it is necessary and necessary to call extremely seriously. However, let's start a conversation about what actions should be taken to solve the problem in a short time frame.

There are situations when you need to connect your phone without a battery. For example, if there is no power source at hand, but you need to check the device's performance or the battery is out of order, but you urgently need to make an important call. Whatever reason you didn't have, if you want to conduct an experiment or just need to be in touch at some particular moment, there is one method on how to connect a phone without a battery. In order to conduct an experiment, you will need not only the device itself, but also a stabilization power supply, a voltmeter, a USB cable, an uninterruptible power supply, a soldering iron, rosin, solder, and flux. Without these things, you won't be able to start your phone without a battery. The fact is that the operation of electronic devices is not possible without batteries, so it is not so easy to turn on the gadget without a power source. Replacing the "native" battery with an iPhone on your own or turning on the device will not work without it. Therefore, in order for the iPhone to work longer between charges, it is worth purchasing an external battery for the iPhone.

How can you turn on a cell phone without a battery.

Below we provide tips on how to turn on your cell without battery. To begin with, it is worth understanding that the standard usual charger designed to work together with a battery that is capable of delivering a short-term current. You cannot feed the phone directly from it. The fact is that if you try to do this, then the very first time you turn on the transmitter, the voltage will drop to almost zero. The problem will be solved by a power supply unit, which we recommend purchasing from a store. Ideally, the power supply should generate a voltage of 3.7V, given the fact that the current load in this case should be in the range up to 2 A. There may be a slight deviation of these indicators up or down. The most important thing is that at the time of the experiment, the voltage should in no case exceed this value during the load drop or at the time of turning on and off the device. Disconnect your phone and remove the battery. You cannot do this trick with iPhones. In order to remove the back cover, you will need to contact service center... Disconnect the mobile phone and remove the battery. Having found two contacts at the battery with a voltage of 3.2 to 3.7 V and observing the polarity, apply voltage from the power supply to the device to these two contacts. After that, try turning on the power supply and then turning on the gadget. If it does not start, then either you did something wrong, or the device is equipped with a data exchange module with a chip, which is built into the battery. If the device starts up, then it is worth connecting it to an uninterruptible power supply. An external battery cannot make a gadget work without a battery.

Is the phone safe to operate without a battery.

Operating a phone without a battery using the method described above is not only unsafe, but also inconvenient. You will always be tied to one place and will not be able to move around the apartment with the device, much less go out into the street. Also, the operation of the device with protruding wires is not safe. Therefore, it is worth resorting to such measures only as a last resort. If the "native" battery has lost its capacity and does not work, then it is worth buying a new one, for example, from the manufacturer

What are the options to turn on the phone directly without battery

In some situations, you may need to enable mobile phone without battery. It would seem why this is necessary. Anything can happen, for example, when the battery is discharged, you urgently need to call. Of course, if you are away from the electrical network, you can only make a call using an external or. If you are in a room connected to electrical networks, then you can turn on the phone from the outlet without a battery at all. This can be useful when using the device as part of an alarm or security system.

In what situations may you need to turn on the phone without a battery:

• Such activation may be required if the battery is out of order, and you need to make an urgent call. If you just plug the phone into the power or USB jack with a broken battery, it won't turn on. In most modern models, the charger supplies power to the battery, and the phone is powered by it. Therefore, a direct connection may be required;
• A situation often arises when a user buys a new model, and old phone throws. Because it is not used, the battery loses its capacity and fails. Then you remember that the memory of your mobile phone has the necessary contact or cool photos. And you can't turn on the device due to a faulty battery. In this case, a direct connection is also required. After all, you will not buy a battery in order to turn on the phone once;
• And another situation when you may need to turn on your mobile phone directly. Often, old mobile phones are used in various security systems that use dial-up and cellular alerts.

Now, let's figure out how to turn on the phone without a battery.

How to start a phone without a battery?

Turning on the phone through a separate power connector

A dedicated power connector is already a rarity on modern phone models. Although they were common before. If your device has one, then first try turning on the phone through it. This is the easiest, but can only work if the power is not coming from the battery.

Otherwise, you will have to rework the power scheme, and only specialists with appropriate training can handle this. If you are lucky and the device turns on from the power supply, you need to test it in different operating conditions.

Often when a mobile device is connected in this way, it starts to work unstably. Feedback from users who have tried such a connection suggests that in this case, turning on a higher power through the power adapter helps.

Attention! Before doing this, study specifications devices in the passport or on the manufacturer's website. You need to find out the maximum voltage and current for the phone. Choose a power adapter depending on this.

On the forums, you can also find recommendations for replacing the power supply cable with another one with a shorter length and a larger cross-section. Length, cross-sectional area and cable material play a big role in this matter. If they do not meet certain specifications, then the phone will not receive the current required for normal operation. This option for connecting a mobile phone is rarely practical. After all, the devices produced now have a power connector combined with a USB interface. We will talk about them further.

Turning on the phone via USB

At first glance, turning on a mobile phone via a USB interface may seem very simple. But this is far from the case. The telephone accepts limited current through the USB interface. If you connect the device through the "native" charging, then it takes the rated current. If the connection is made from a laptop or computer, then a limit of 500 mA is set.

What are the ways to turn on the phone without battery?

Sometimes on the Internet you can find users' questions about how to turn on a mobile phone without a battery. At first glance, it may seem that this is self-indulgence. But it only seems so. For example, the battery is completely discharged, and you need to make an urgent call. If you are far from the outlet, then, of course, you will need accumulator battery... But if you are in a building where there is electricity, then you can easily turn on your mobile phone without a battery. In addition, a similar smartphone connection scheme is often used when integrating it into a security system and alarm system. In this post, we will look at several options for how to turn on your phone without a battery.

Situations that require the phone to turn on without a battery

Here are some examples of when you might need it:

• The battery is broken or flat and you need to make a call. If you turn on the phone through the power connector or USB port while the battery is not working, it will not work. Many modern phones have a circuit in which the power is shorted to the battery, and already from the battery power is supplied to the microcircuit. So, in this situation, you will need to directly connect the power to the smartphone;
• Another situation is when you bought a new model and forgot about your old smartphone. It lay there for a while, and the battery in it lost its capacity. After a while, you remembered that the necessary information remained in the phone, for example, contacts, photos, videos. Don't buy a new battery just to pull out images? In this case, turning on the phone without a battery will help;
• And also the situation mentioned above. There may be a need to use an old smartphone in alarm systems that work by dial-up and send alerts over the network. Here you need the smartphone to be on all the time. Therefore, it turns on directly without a battery.

Let's see the methods of turning on the phone without a battery.

Switching on via a separate power connector

Modern phones have already lost a separate power connector, but they were common on older models. If your phone has such a connector, then first try to connect using it. If the power goes through it, this will be the easiest solution to the problem.

Otherwise, you will have to consider other connection options. In most cases, this is due to a modification of the power supply circuit. Here you will need certain skills and abilities in the field of electrical engineering.

Switching on the phone without battery via USB

It seems that this option suggests itself and is the simplest. However, this is not easy. The phone draws a limited current through the USB port. The device takes the rated current only if it is connected via a charger from the complete set. If you connect your phone to a laptop USB, the current is limited to 500 mA. With this restriction, the smartphone will not work or be unstable.

Power on directly without battery

In order to connect a mobile phone directly without a battery, you will need:

• Power adapter (nominal 3.4-4.5 V). It is highly desirable that it has short circuit protection;
• Soldering iron and solder;
• Multimeter.

Those who are versed in electrical engineering can assemble a power adapter with the desired characteristics from separate components.

Determine the polarity of the battery terminals with a multimeter. This will set the polarity of the mobile phone leads. Solder the wires from the selected power adapter to these pins. If turning on the phone without a battery is required for one time, then connect the wires using crocodile clips. After that, plug the adapter into the network and turn on the smartphone.
