In life, there are situations when you are waiting for an important call and are surprised to understand that the smartphone’s battery is completely discharged. After reading today's article, you will learn how to turn on your cell phone without a battery.
When does this need arise?
At first glance, this is completely useless knowledge that is unlikely to ever be useful to anyone who monitors the state of the battery of their own device. However, information on how to turn on the 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 come in handy if you need to make an urgent call if the factory battery has ordered a long life. Suppose you purchased a new smartphone, and the old one was gathering dust on a table for a long time. As a result, its battery is completely discharged, and the files you need are stored in the device memory. To get to them, it is not necessary to purchase a new battery. It is in such situations that people often have the question of how to turn on a mobile phone without a battery.
In case of emergency, you can try to briefly "resurrect" the mobile device. This can be done in several different ways.
What will be required to achieve the desired result?
To turn on a fully discharged smartphone, you need to stock up on a stabilization power supply, a voltmeter, a flux, rosin, solder, a soldering iron, a USB cable and an uninterruptible power supply. With the help of this simple kit, you can reanimate your mobile device yourself.
Action algorithm
Those who do not know how to turn on the phone without a battery should remember that the standard charger is designed to work together with the base battery, which is capable of producing short-term significant current. If you directly connect a smartphone to it, then the first time you turn on the transmitter, the voltage will drop to almost zero.
Before you turn on the phone without a battery, you need to get a stabilization power supply with built-in short circuit protection. Such a device can be purchased at a specialized store or made independently. The voltage generated by it should be 3.7 V.
The switched off mobile phone must be disconnected from the standard charger and the battery removed. Next, you need to find two contacts on the battery, the voltage on which varies from 3.2 to 3.7 V. This can be done using a voltmeter.
Not forgetting to observe 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 exclusively as an element of the security system in the future can be recommended to turn off the power supply. You can also solder the junction of the contacts.
Then you need to turn on the power supply and try to activate the mobile device. If everything worked out for you, then the gadget is not equipped with a module for exchanging information with 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 if there is electricity.
In order to ensure their own safety, it is necessary to refrain from carrying out such experiments and use the similar method only in exceptional situations. Do not neglect the fact that in case of strong heating, the telephone battery may explode.
How can I turn on the phone without a battery via the USB interface?
At first glance, this is one of the simplest and most obvious ways. But actually it’s a bit more complicated. USB mobile devices can receive current with restriction. Basic charging transfers the rated current to the smartphone. When connecting it to a computer or laptop using a USB cable, the limit is 500 mA.
Those who wanted to figure out how to turn on the phone without a battery would need to find the ability to connect a charger without using a battery.
