Step-by-step battery replacement plan

After you buy the right tools and a suitable battery for the repair, it is important to follow the right steps. Below we have written out a roadmap for you:

Step 1: Turn off the phone

Before starting battery replacement, it is very important to turn off the phone and use the anti-static mat and wrist strap to avoid electrical accidents.

Step 2: Open the back of the housing and remove the center frame

Carefully remove the screws securing the back of the phone with an appropriate screwdriver to open the case. Then remove the center frame to gain access to the battery. If the back cover is firmly attached to the frame with glue and does not come off easily, you can heat it up to ease the process

Step 3: Remove the old battery

Use a small amount of alcohol and heat the battery to make it easier to remove it with an opening tool. Be careful not to cause any damage. Next, clean the battery compartment with a microfiber cloth. This exact process may vary by phone model, but with most models, these are the correct steps.

Step 4: Insert the new battery

Insert the new battery into the battery compartment and reconnect it to the motherboard.

Step 5: Close the housing

Carefully close the housing and secure it with the screws you removed earlier.

Step 6: Battery check

Turn on the phone and check that the battery is functioning properly.

By following these steps and tips, you can professionally replace your phone battery.


When performing the repair, it is important to have the right tools on hand so that the process goes off without a hitch. Make sure you have an anti-static mat and wrist strap to prevent electrical accidents. These tools help dissipate static electricity, which can prevent damage to the phone's delicate electronics.

It is also very important to follow the step-by-step plan carefully. By performing each step accurately, you minimize the risk of mistakes and increase your chances of a successful repair.
