How can I turn on the phone without the battery with the available tools?

In life there are situations when you are waiting for an important call and are surprised to understand that the battery of the smartphone is completely discharged. After reading today's article, you will learn how to turn on a cell phone without a battery.

When does this need arise?

At first glance, this is completely useless knowledge, which is unlikely to ever be useful to anyone who follows the status of the battery of his device. However, information on how to include a phone without a battery can be useful in cases where the gadget is used as one of the elements of the security system.

Also, such knowledge will be useful in case of necessity to make an urgent call, if the factory battery ordered to live long. Suppose you purchased a new smartphone, and the old one was gathering dust for a long time in the table. As a result, its battery is completely discharged, and the files you need are stored in the device's memory. To get to them, do not necessarily purchase a new battery. It is in such situations that people often have a question about how to turn on a mobile phone without a battery.

In case of emergency, you can try to briefly "resurrect" the mobile device. You can do this in several different ways.

What will it take to achieve the desired result?

To turn on a fully discharged smartphone, you need to stock up with a stabilization power supply unit, voltmeter, flux, rosin, solder, soldering iron, USB-cord and uninterruptible power supply. With this simple package you can independently reanimate the mobile device.

Algorithm of actions

Those who do not know how to turn on the battery without the battery, should remember that the standard charger is designed to work together with a basic battery that is capable of short-term output of significant current. If you directly connect a smartphone to it, the first time you turn on the transmitter, the voltage will drop almost to zero.

Before you turn on the battery without the battery, you need to acquire a stabilization power supply with built-in protection against short-circuit. Such a device can be purchased at a specialized store or made independently. The voltage it produces must be 3.7 V.

Turn off the mobile phone and disconnect it from the standard charger and remove the battery. Next, you need to find the battery two contacts, the voltage on which varies from 3.2 to 3.7 V. You can do this with a voltmeter.

Do not forget about the observance of the polarity, you should apply voltage to the corresponding contacts of the battery compartment of the mobile device. Those who decided to use this device in the future solely as an element of the security system, you can recommend to de-energize the power supply. It is also possible to solder connection junctions.

Then you need to turn on the power supply and try to activate the mobile device. If you succeeded, the gadget is not equipped with a module for exchanging information from a chip mounted in a battery. This indicates that it is suitable for use in security systems. In this case, the phone is able to function without a battery, but only with electricity.

In order to ensure their own safety, it is necessary to refrain from carrying out similar experiments and to use this method only in exceptional situations. It is not necessary to discount that in case of strong heating the telephone battery can explode.

How can I turn on the phone without a battery through the USB interface?

At first glance, this is one of the simplest and most obvious ways. But in reality everything is a little more complicated. Mobile devices on the USB interface can accept a current with a limitation. The base charge transfers the nominal current to the smartphone. When connected to a computer or laptop via a USB cable, the limit is 500 mA.

Those who wanted to figure out how to turn on the battery without the battery, will need to find the opportunity to connect the charger without using the battery.
