A phone's battery is designed to last for a certain amount of time before it needs to be charged, usually between 3-4 hours. However, there are times that you need your phone to stay alive beyond what the battery can provide.

You might have used up all your batteries or forgot them at home while you go out with friends and family. Whatever the reason, you would like to use your phone for as long as possible before getting another charge or replacing another battery. You can prolong your phone's life by transferring its old battery to another cell phone.

What is Required?

1. A functioning cell phone that has an old battery you want to replace

2. An extra working cell phone with its own existing battery

3. Both phones must have the same type of battery

How to Transfer Battery to Another Phone

If you have an old phone that still has a functional battery but doesn't work anymore, use the battery in another phone. This way, your other phone's battery can get extended life while you save up for a new one or replace it. Here is what you need to do:

1. Charge both phones

Before transferring the batteries, make sure that both phones are fully charged. This will reduce the power consumption of the phone with the low battery, which saves it from getting discharged too quickly.

2. Power off the phone with no battery

Turn off your phone without a battery first before opening its back compartment to remove the battery. If you don't do this, there is a chance that you might accidentally turn the phone on again and shorten the life of your low battery. If you don't know how to shut down your phone, read your user manual or consult an expert for further instructions.

3. Remove the battery from the old phone

The back compartment of most mobile phones can be removed without using any tools. To remove it, stick a fingernail at the crevice between the back cover and the phone or simply pry off using your teeth. Once you've removed it, carefully remove the battery from its compartment by sliding your fingers along its side to take it out.

4. Place the new battery in the old phone

With both batteries removed, place the new one in the old phone and use a piece of tape to hold it in place. You can also use silicone or rubber bands to firmly secure the battery. Make sure that it fits well into its compartment and is secured firmly without falling out.

5. Power on your old phone

Turn on your old phone with the new battery and it should turn on properly. If the phone turns on, you have successfully transferred your battery.

6. Power off the old phone with new battery

To save power, turn off your old phone as soon as the process is done. To do this, press and hold down its power button for a few seconds until it shuts off completely.

Remember that transferring your battery with another allows you to save power. But if the batteries are not compatible, it could explode or cause other problems. Make sure that both batteries have similar milliamps, voltage, and the same brand before attempting to transfer them. If they don't match completely, use a damp cloth to wipe off all conductors from the positive and negative points of both batteries. Once they are completely dry, try transferring them again until they fit properly.

You have just successfully transferred a battery from one phone to another using simple materials that you can find in your house. This way, you can maximize the use of your old phone whenever it is needed for emergencies or other important reasons.


All batteries will eventually run out of power. Sooner or later, you will need to replace your battery with a new one or charge it again. But if you are low on budget and can't afford another battery right now but still need to use your phone, you can transfer the power of its good battery into another working phone with similar features. This will give you the option of extending your phone's battery life and maintaining its functionality.

You can use this trick on most phones that have removable batteries with a few exceptions.
