When a phone's battery has run out of power or has been low for a long period of time, it no longer supplies power to your device. If your phone's battery no longer works, you don't need to throw it away right away, as you may be trying to get it back. Maybe all batteries just need a push to get going. Learn how to do it starting with the first method.
Steps
Method 1 of 2: Restart the Battery
Step 1. Get what you need
Just like a car battery, you can restart a phone's battery, charging it enough to turn the phone on. For this procedure you will need:
- A 9 volt battery will do any brand as long as the battery is 9 volt.
- Insulating tape, approximately ten centimeters long.
- Electric cables, a simple electric cable will do just fine.
Step 2. Connect the electrical wire to the positive and negative poles of the 9 volt battery
You can identify the charges of the poles simply by the positive (+) and negative (-) signs placed near the poles. Remember to use two separate cables or split the cables for each pole.
Do not use a single cable to connect the positive and negative poles otherwise the battery could be damaged
Step 3. Cover the connections with electrical tape
Mark which pole of the battery the cable is to be connected to.
Step 4. Connect the cable with the positive pole of the battery to the positive pole of the battery
- Do the same step with the negative poles.
- Do not connect the opposite poles or you will short-circuit the phone battery.
Step 5. Cover the wire connections between the 9 volt cell and the phone battery with electrical tape to secure the connections between the wire and the battery posts
Step 6. Leave everything plugged in for about a minute, until the phone's battery gets warm
Put the battery in a dry and cool place, away from water and heat sources
Step 7. Unplug the connections once the battery is warm to the touch
Step 8. Insert the battery into your phone and check if it turns on
Step 9. Once the phone is powered on, check the battery level
If the level is low, put the phone on charge until it is fully charged.
Method 2 of 2: Freeze the Battery
Step 1. Remove the battery from your phone
Step 2. Put it in a hermetically sealed plastic bag to prevent it from getting wet
Do not use paper or aluminum bags because water penetrates easily
Step 3. Place the plastic bag in the freezer overnight or for at least 12 hours
Use a container or bowl to prevent the battery from coming into direct contact with the freezer and then sticking, causing removal problems.
By exposing the battery to low temperatures, such as the freezer, you will allow the battery to charge enough to turn the phone on and charge the battery
Step 4. Take the bag out of the freezer
Wait until it is at room temperature.
DO NOT use the battery while it is still frozen
Step 5. Dry the moisture from the battery
Step 6. Plug it into your phone and check if it turns on
Step 7. Once the phone is turned on, check the battery level
If the level is low put the phone on charge until it is fully charged.
Warnings
- Do not leave the phone battery connected to the 9 volt battery, as it may explode.
- Your phone's battery may explode even if left in the freezer for too long. Remember that extreme temperatures damage batteries.
Advice
- If you're having trouble with your battery, try changing the charger to rule out that that's the problem. Most battery problems can be solved by changing the charger.
- Do not recharge your phone battery using a 9 volt battery as it may burn or explode. This method only works with a battery with no liquid to be recovered.
- When leaving the battery in the freezer, make sure the plastic bag is tightly sealed and placed away from food to avoid contaminating it in case it explodes. Also, properly label your battery to prevent other people mistaking it for food.
