- How do I use a smartphone directly without a battery?. How to turn on the mobile phone without battery? In this video, we turn on a Huawei Honor 3C Lite type mobile phone without using a battery and with a voltage reducer module.
Using an old normal adapter (it doesn't matter what voltage it is) and LM2596 step-down module, we turned this old mobile phone into a landline phone.
--------------------------------
Warning: Mobile phone batteries have different voltages. In this video, the battery voltage is 3.9 volts.
Warning: The battery power input terminals in different mobile phones may be different.

Only 26 likes and four comments. I wonder why. This is by far, the most convincing video that I came across on the youtube about using phones without battery. Thank you!!
Thank you for your encouraging message. I hope you will support us by introducing newtecpro RUclips channel to your friends
wont work on most of the phones without 10k resistor between + and middle contact (thermistor in battery)
Thanks for sharing your experience. If a more complete explanation is needed, tell me so that I can edit the text of the explanation and share it with others
Hello, I have a current Samsung tablet. I remove the card on the battery and power it up by applying power to the +- terminals. However, as the tablet runs, it detects that there is a real battery and the battery percentage runs out and shuts down. Do you have any ideas about this?
Thanks a lot! But please what if I want to do it with 10 or more phones. I have looked at adjustable power supply, but hope you might have a good advice. The problem for me as a traveler is also weight, and space in the luggage. I need to remove the batteries, because it's not accepeted in the check in baggage, and also not to much in carry on. (I am also thinking about using power from my laptop)
Can you turn on all mobile phones or only one of them? It is important that mobile phone batteries have the same voltage and amperage. If the voltage and amperage are the same, you can connect female plugs to all mobile phones according to the video. When needed, connect the STEP-DOWN power supply to any one you want
Will It Work With LG V20 ? AND also Tell How Long We Can use With This Method ? Can i use a mobile for 4 or 5 hours continuesly??
The model of the mobile phone does not make a difference. You just have to be careful that the + and - pins of the power input in different mobile phones may be different
Also, the voltage of the batteries of different brands of mobile phones is different. So, you must adjust the voltage output exactly according to the battery output
We have launched this mobile phone for more than 2 years and it is working without any problem
Can you check how much amps does it draw when booting up. Mine is not switching on.
This reducer module has an output of 2 amps. So below is 2A.
Can I use this module while connect phone to pc via usb cable?
Yes you can. This module is responsible for powering and powering the phone and does not have any other effect on the mobile phone
@@newtecpro thank you!
Is that safe.. because I have phone that I can't use because I don't have the budget to buy battery and it's also hard to find the type of battery... what is the usual voltage to start a phone..
This method is safe. As long as you choose the voltage accurately. Please check the output voltage of your mobile phone battery. The output should be exactly the same as the output voltage of the original mobile phone battery.
Also, the power sockets in different devices may be different. Check which pins the + and - pins are connected to?
The output voltages may dropped thats why it shows the battery only at 71percent. Your dc to dc converter may burnt for long time operation. You must use a higher amperage for prolonged operation.
Thank you for the important point you mentioned. According to you, can the voltage be increased by 30%? That is, whatever the battery voltage is, the power supply voltage should be about 30% higher?
Is it possible to power the phone with 5v adepter?
No, you must match the voltage with the battery voltage. Bring the 5V to the battery voltage with the step-down module
@@newtecpro if i connect battery bms with 5v adapter & plugin to phone then is it possible to power the phone?
@@warmachine676 I hope I understood your meaning well. Yes, you can specify the voltage that is equal to the original battery of the mobile phone. This voltage can be with an adapter or battery or other DC power sources that can precisely adjust the output voltage.
Ja som takto riešil tablet, ale neviem aký odpor by bol vhodný na tretí prívod. Neviete poradiť, ako sa to zisťuje?
Please make your question more clear. If you use the voltage reducer module, you don't need to use anything else
Please make your question more clear. If you use the voltage reducer module according to the video, there is no need to use anything else.
@@newtecpro I put the module, 4,5V, and 15 kohm resistor between - and 3. contact. Battery level is 82% but it goes down over time. I didn't use the battery module because it got very hot, even though I only put 4.2V. There was also a problem with the start-up and the battery showed only 30%.....
Do this as a conversation starter when boring company comes over, rather than various magic tricks.
thnx
It works But a messege shows up "please make sure you are using a compatible battery and charger" when I connect charging(and Data together) cable to PC through USB Port for data transmission ,Will this damage the phone?Another problem is phone can't be turned on when regulated power and data transmission cable are both connected to the phone ,is it normal?
Does this message appear 1 time or 2 times and you no longer see this message? If so, ignore it. Otherwise, the problem should be investigated
@@newtecpro I ignored, and the message fixed, but everytime when I press OK then the message appears again soon. How about the problem regarding to the phone can't be turned on when regulated power and data transfer cable(with +5V ) are both connected to the phone ,can explain? Thanks.
@@黃士熙-w5r If I understand correctly, your problem occurs when you connect the data cable. It is better to transfer data in another way. And use the mobile phone in this way as a fixed phone (only for answering the phone)
I will run my phone in this way : connect data cable when needed after the phone is fully turned on.Thank for your answer.
Since the resistor tricked the phone into thinking that a battery is present, why not then simply connect the power source into the phone USB port?
The output of the USB port is 5V while we need a 3.8V power supply here. So we have to bring it to 3.7 to 3.9V with the voltage reducer module
@@newtecpro I know. I am only interested in knowing whether the 3.9v can then go through the USB port instead of making a hole in the back cover.
@@lwh7301 No, this is not possible. Or at least we didn't find a way to do it
How to make it with LED that show us the phonw is on ?
I did not understand your question correctly. But you can put an LED with a suitable voltage (equal to the output of the reducer module) on the output path so that it lights up when connected.
Saya memcoba nya tpi berlaku intk adaptor 2/3ampere baru bsa nyala.tdk bsa pakai power bang jadi di bikin modem rumahan saja.
Thank you for sharing your experience with us
Really bad idea! Now, no longer called mobile phone!!! Went back to old century!!!!
Yes, you are right to some extent. But it has these conditions. For example, you need a landline phone without the hassle of changing the battery. Here you can use the phone without battery without spending money.
It is also a good idea in terms of not polluting the environment. Batteries cause a lot of damage to the environment.
hey friend, if you are still active around here i have a question, if i connect the red and black wire to a power bank instead of a 5v power brick would i be able to use the power bank like an external battery because the converter would step down the voltage to 3.8v anyway?
Hello. Yes, if you use a power voltage converter, the output voltage will always remain constant. You can use a power bank. The step-down converter module can reduce the voltage to 3.8 and keep it in this range
@@newtecpro thank you for reaching back, I will try this and i thought the same too, it would reduce the voltage to a constant. Thank you.
