The Samsung Galaxy S7, launched in March 2016, remains a beloved smartphone for many users around the globe. Its sleek design, impressive camera capabilities, and robust performance have left a lasting impression.

In this comprehensive guide, we’ll walk you through step-by-step on how to replace the battery on your Samsung Galaxy S7, ensuring that you can access the device’s full potential once again.
Understanding the Importance of a Healthy Battery
Before diving into the replacement process, it’s essential to understand why maintaining a healthy battery is crucial for your smartphone’s performance. The battery is the heart of any mobile device; without it, your phone is essentially a small tablet. Keeping your Samsung Galaxy S7’s battery in top shape can lead to:

Step-by-Step Guide to Replacing the Battery on a Samsung Galaxy S7
Now that you’re prepared and armed with the right tools and knowledge, it’s time to replace that battery. Follow these detailed steps to ensure a successful operation.
Step 1: Power Down Your Device
Before starting the replacement process, it is crucial to turn off your Galaxy S7 completely to avoid any electrical issues. Hold the power button until the power menu appears, then select “Power off” to switch off the device.
Step 2: Open the Back Cover
The Samsung Galaxy S7 has a glued back cover, which means you’ll need to apply some heat to loosen the adhesive.
Applying Heat
Using a heat gun or a hairdryer, gently heat the edges of the back cover for about 30 seconds. Make sure not to overheat the device, as excessive heat can damage the internal components.
Inserting a Plastic Opening Tool
Once heated, take your plastic opening tool and carefully insert it into the seam between the back cover and the frame of the phone. Slowly slide the tool around the edges to separate the adhesive. Lift the back cover gently, being cautious not to disrupt the internal components.
Step 3: Disconnect the Battery
With the back cover removed, you’ll see various internal components. Locate the battery connector, which is usually covered by a small protective plastic cap.
Removing the Connector
Use your precision screwdriver to remove any screws securing the connector cap, then gently lift the cap. Next, use tweezers to carefully disconnect the battery cable from the motherboard. Take your time during this step to avoid damaging any components.
Step 4: Remove the Old Battery
Next, it’s time to remove the aging battery.
Lifting the Battery
The battery is held in place by strong adhesive. Use your plastic opening tools or a spudger to gently pry the battery away from its housing. Apply heat again if needed to help loosener it. Be very careful, as puncturing the battery can be hazardous.
Step 5: Insert the New Battery
Now that the old battery is out, it’s time to insert the new one.
Placing the New Battery
Take your new Samsung Galaxy S7 battery and carefully position it in the battery compartment. Make sure the battery connector aligns with the connector on the motherboard.
Step 6: Reconnect the Battery
Once the new battery is in place, reconnect the battery connector to the motherboard. If applicable, replace the protective cap and secure it with screws.
Step 7: Reattach the Back Cover
After ensuring everything is securely in place, it’s time to reattach the back cover.
Aligning the Cover
Carefully align the back cover and press it back into place. If necessary, apply some additional heat to the edges to re-establish the adhesive.
Ensuring Secure Closure
Press firmly along the edges to ensure a tight seal. You may want to keep the phone powered off for a while to let the adhesive set properly.
Step 8: Power On Your Samsung Galaxy S7
Finally, it’s time to power on your device. Press and hold the power button until the Samsung logo appears. Once booted up, check your battery status to ensure everything is functioning correctly.
Best Practices for Battery Maintenance
After replacing the battery, keeping it in good condition is essential for optimal performance.
Avoid Extreme Temperatures
Extremes of heat or cold can damage batteries. Try to use and store your device in a temperature-controlled environment.
Limit Fast Charging
While fast charging is convenient, using it excessively can lead to battery wear. Opt for standard charging when possible to prolong battery lifespan.
Regular Calibration
Every once in a while, let the battery drain completely before fully charging it again. This practice can help recalibrate the battery’s internal indicator, giving you a more accurate representation of its charge level.
Monitor Battery Health
There are applications available that can help you monitor the health of your newly replaced battery. Keeping an eye on its performance can alert you of any issues early on.
