As smartphones become an integral part of our daily lives, the importance of maintaining their functionality—particularly the battery—cannot be overstated. The Samsung Galaxy S7, launched in 2016, is still a widely used device thanks to its remarkable features and sturdy design. However, like any good thing, time can take its toll, and battery life diminishes. If you’ve noticed that your Galaxy S7 isn’t holding a charge like it used to or drains unusually fast, it may be time to change the battery. This comprehensive guide will walk you through the process, ensuring that you can complete this task safely and effectively.
Why Change Your Galaxy S7 Battery?
Understanding the reasons behind changing your Galaxy S7 battery can help you make an informed decision. Here are a few why you might want to replace it:
- Battery Degradation: Over time, lithium-ion batteries lose their capacity to hold a charge. External factors like temperature and usage can accelerate this process.
- Better Performance: A new battery can significantly improve your phone’s performance, enabling longer usage times between charges and faster charging.
- Cost-Effective Solution: Instead of buying a new phone, changing the battery is often a more economical and sustainable option, especially if the device is still functional.
Preparing for the Battery Change
Before diving into the replacement process, it’s essential to prepare adequately. Here’s a checklist of what you need:
Tools Required
- Phillips screwdriver (size 00)
- Plastic prying tool
- Plastic tweezers
- New Samsung Galaxy S7 battery
- Heat gun or hairdryer (optional)
- Anti-static wrist strap (optional but recommended)
Safety Precautions
Taking necessary precautions is crucial to avoid damaging your phone or injuring yourself during the process:
- Power Down the Device: Always shut down your phone before starting any repair.
- Work in a Static-Free Environment: To prevent damage to electronic components, it’s advisable to work in an environment that is free of static electricity.
- Handle Components with Care: Be gentle when handling the parts of your smartphone, especially the connectors.
Step-by-Step Guide to Changing the Battery in a Samsung Galaxy S7
Now that you are well-prepared, let’s get into the nitty-gritty of changing the battery. Follow these steps carefully.
Step 1: Remove the Back Cover
The Samsung Galaxy S7 features a glass back, making it a bit tricky to remove. Here’s how to do it:
- Heat the Edges: If you have a heat gun or hairdryer, warm the edges of the phone for 30 seconds to one minute. This will soften the adhesive that holds the back cover in place.
- Insert the Prying Tool: Once heated, carefully insert the plastic prying tool between the glass back cover and the frame. Gently work your way around the edges to loosen the adhesive.
- Remove the Cover: Once you have loosened it adequately, lift the back cover away from the phone.
Step 2: Disconnect the Battery
With the back cover removed, the next step is to access the battery:
- Locate the Battery Connector: Find the battery connector, which is usually protected by a mid-frame cover.
- Remove the Mid-Frame: Use a Phillips screwdriver to remove the screws holding the mid-frame in place. Once the screws are removed, use the prying tool to lift the frame carefully.
- Disconnect the Battery: Carefully lift the battery connector off the motherboard.
Step 3: Remove the Old Battery
Now that you’ve disconnected the battery, it’s time to take it out. This can be a bit challenging due to the adhesive.
- Loosen the Adhesive: Use the heat gun or hairdryer again, applying heat to the battery area for about 30 seconds. This will help soften the adhesive.
- Gently Pry Out the Battery: Using the prying tool, carefully lift the battery out of its compartment. Be cautious and avoid damaging any surrounding components.
Step 4: Install the New Battery
With the old battery out, installing the new battery is relatively straightforward.
- Position the New Battery: Place the new battery into the compartment, ensuring that the connectors align properly with the motherboard.
- Reconnect the Battery: Secure the battery connector back onto the motherboard, ensuring it clicks into place.
Step 5: Reassemble Your Galaxy S7
Now that the new battery is installed, it’s time to put your device back together:
- Replace the Mid-Frame: Align the mid-frame back onto the chassis and fasten it using the screws you removed earlier.
- Attach the Back Cover: Apply gentle pressure around the edges of the back cover to reseal it. You may also consider adding adhesive strips or double-sided tape for security if the original adhesive isn’t strong enough.
Step 6: Power Up and Test
With everything reassembled, it’s time to power up your device.
- Turn on Your Galaxy S7: Press and hold the power button until the Samsung logo appears.
- Check Battery Performance: Once the device is fully booted, use it for a while to ensure the new battery is functioning as expected. Monitor charging times and battery performance to confirm improvements.
Troubleshooting Common Issues
Sometimes, after changing the battery, you may encounter issues. Here are a couple of common problems and solutions:
Phone Won’t Power On
If your Galaxy S7 doesn’t power on after replacing the battery:
- Check Connections: Ensure the battery connector is securely attached to the motherboard.
- Try a Different Charger: Sometimes, the issue lies with the charger or charging cable. Test with a different charger to rule out this possibility.
Battery Drains Quickly
If you notice that your new battery drains rapidly:
- Check for Background Apps: Some applications running in the background can consume a lot of battery. Review your device settings to identify and close such apps.
- Update Software: Sometimes, software updates contain optimizations that can improve battery performance.

Additionally, if you prefer not to handle the replacement yourself, local repair shops often sell batteries and provide installation services. This can save you the hassle of DIY installation while ensuring that your new battery is properly put in place by professionals.
Will changing the battery void my warranty?
Changing the battery in your Samsung Galaxy S7 could potentially void your warranty, especially if you do not do it through authorized channels. Many manufacturers, including Samsung, have specific guidelines related to warranty coverage, and unauthorized repairs or replacements might lead to a denial of warranty claims if issues arise later on.
If your device is still under warranty, it’s wise to contact Samsung or the retailer where you purchased the phone to understand your options. Discussing the battery issue with them first can help determine whether battery replacement is covered and if there are authorized methods to do it without jeopardizing your warranty.
What precautions should I take before starting the battery replacement?
Before starting the battery replacement process for your Samsung Galaxy S7, it’s essential to take several precautions. First, power down your device completely to avoid any electrical issues or damage while working on the internals. Remove the SIM card and memory card to prevent loss or damage during the repair process.
Additionally, ensure that your work environment is clean and free of static electricity. Use an anti-static wrist strap if possible. Having a clear, organized work area can help you keep track of screws and small components as you disassemble your phone, reducing the risk of losing any parts or causing accidental damage.
