Removing the battery from a Samsung phone can be a necessary step for various reasons, such as replacing a faulty battery or resetting the phone. Here’s a comprehensive guide on how to safely and effectively remove the battery from a Samsung smartphone.
1. Prepare Your Samsung Phone
a. Power Off Your Phone
Before attempting to remove the battery, it’s crucial to power off your Samsung phone. This ensures that no data gets corrupted, especially if the CPU is writing data. To switch off the phone safely, press and hold the Power button until the device powers down.
b. Discharge the Battery
For safety, discharge the battery below 25% before starting the disassembly process. This step is particularly important for newer Samsung Galaxy models like the S21, as it reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
2. Accessing the Battery
a. Locate the Groove
Find the groove typically located around the corners of your Samsung device. This groove allows you to pry open the backplate of your phone. Apply a little force to pull out the backplate. Once the backplate is removed, the battery, SIM card, and microSD card will be exposed.
3. Removing the Battery
a. For Older Models
b. For Newer Models
For newer models like the Samsung Galaxy S20 or S21, the battery is held in place with strong adhesive. You’ll need a high concentration (over 90%) isopropyl alcohol to loosen and release this adhesive. Carefully apply the alcohol around the edges of the battery and gently pry it away. Remember to handle the battery with care, especially if it’s swollen, and avoid using heat to loosen the adhesive, as this can be dangerous.
4. Safety Precautions
a. Handling Swollen Batteries
If the battery is swollen, take appropriate precautions. Swollen batteries can be hazardous and should be handled with care. Do not apply heat or puncture the battery, as this can lead to dangerous situations.
b. Avoiding Heat
Do not use heat sources like hair dryers or heat guns to loosen the adhesive, as this can cause damage to both the battery and the phone’s internal components.
Removing the battery from a Samsung phone, whether it’s an older model with a removable backplate or a newer model with a glued-in battery, requires careful handling and attention to safety. Always power off the phone and discharge the battery for safety, and use the right tools and techniques depending on your phone model. If you’re not confident in doing this yourself, consider seeking professional help.
