The Samsung Galaxy S series has been a benchmark for Android smartphones for years, and each new iteration brings exciting features, improvements, and innovations. If you’re currently using a Galaxy S7, you might be wondering if it’s time to upgrade to the latest and greatest, the Galaxy S21. In this article, we’ll dive into the key differences between the two devices, exploring what’s changed, what’s improved, and what’s remained the same. By the end of this article, you’ll have a clear understanding of whether upgrading from the S7 to the S21 is right for you.
Design and Build Quality
One of the most noticeable differences between the S7 and S21 is their design and build quality. The S7, released in 2016, features a more angular design with sharper edges, while the S21, launched in 2021, boasts a more refined, curved design with rounded edges. The S21’s sleeker design makes it more comfortable to hold and easier to maneuver, especially for those with smaller hands.
The S21’s screen is also larger and more vibrant, with a 6.2-inch Dynamic AMOLED display compared to the S7’s 5.1-inch Super AMOLED screen. The S21’s higher screen resolution (1440 x 3200 pixels) and higher pixel density (540 pixels per inch) provide a more immersive viewing experience, making it perfect for streaming, gaming, and browsing.
Durability and Water Resistance
Both the S7 and S21 feature IP68 water and dust resistance, meaning they can withstand accidental splashes and spills. However, the S21 takes it a step further with a more durable design and improved scratch resistance. The S21’s rear glass panel is made from tougher, more resistant materials, reducing the likelihood of scratches and cracks.
Performance and Hardware
The performance gap between the S7 and S21 is substantial. The S7’s Qualcomm Snapdragon 820 processor was a powerhouse in its time, but it’s significantly slower than the S21’s Qualcomm Snapdragon 888 5G chipset. The S21’s processor offers:
- Faster processing speeds (up to 2.9 GHz)
- Enhanced artificial intelligence capabilities
- Improved multitasking and app switching
The S21 also boasts more RAM and storage options, with up to 16GB of RAM and 512GB of internal storage. This means you can store more apps, files, and media, and enjoy seamless performance even with demanding tasks.
Battery Life
The S21’s larger 4500mAh battery provides a significant upgrade over the S7’s 3000mAh battery. This translates to:
- Longer battery life, with up to 12 hours of internet use
- Faster charging speeds, with support for 25W fast charging and 15W wireless charging
- Improved power-saving features, such as adaptive battery management and power-saving modes

| Storage | Up to 64GB | Up to 512GB |
| Battery | 3000mAh | 4500mAh |
Camera Capabilities
The camera department is where the S21 truly shines. The S7’s 12-megapixel rear camera was excellent in its time, but the S21’s quad-camera setup is a significant upgrade:
- A 50-megapixel primary sensor with a larger aperture (f/1.8) and improved optical image stabilization
- A 12-megapixel front camera with a wider aperture (f/2.2) and enhanced selfie capabilities
- A 12-megapixel telephoto lens with 3x hybrid zoom and 30x digital zoom
- A time-of-flight camera for enhanced depth sensing and bokeh effects
The S21’s camera app is also more feature-rich, with advanced modes like Super Steady video stabilization, Live Focus, and more.
Software and Security
The S21 runs on Android 11 out of the box, with Samsung’s One UI 3.1 skin on top. This means you’ll enjoy a more modern, streamlined interface with improved performance and security enhancements. The S7, on the other hand, is still stuck on Android 10, with an older version of One UI.
The S21 also features more advanced biometric security options, including an in-display fingerprint sensor and improved facial recognition technology.
Additional Features
The S21 offers several features that are missing from the S7:
- 5G connectivity for faster data speeds and lower latency
- Wi-Fi 6 support for faster and more reliable wireless connectivity
- A larger, more comfortable design with a more seamless in-hand feel
- Enhanced audio capabilities, including improved speaker quality and support for Dolby Atmos
Should You Upgrade?
So, should you upgrade from the S7 to the S21? The answer depends on your individual needs and preferences.
If you:
- Value a larger, more vibrant display
- Need improved performance and multitasking capabilities
- Want enhanced camera features and better image quality
- Desire the latest software and security updates
- Are willing to invest in a newer, more feature-rich device
Then, yes, upgrading from the S7 to the S21 is a great idea. The S21 offers significant improvements in design, performance, camera capabilities, and software features that make it a worthwhile upgrade.
On the other hand, if you:
- Are on a budget and don’t want to spend money on a new device
- Are happy with the S7’s performance and features
- Don’t need the latest and greatest technology
Then, no, sticking with the S7 might be the better option for you.
Ultimately, the decision to upgrade depends on your individual needs and priorities. We hope this article has provided you with a comprehensive overview of the key differences between the S7 and S21, helping you make an informed decision about whether to upgrade.
Is the Samsung S21 worth the upgrade from the S7?
The Samsung S21 is definitely worth considering as an upgrade from the S7, especially if you’re due for a new device. The S21 boasts significant improvements over its predecessor, including a faster processor, better camera, and larger display. Additionally, the S21 has features like 5G connectivity, a bigger battery, and more storage options, making it a more future-proof device.
However, whether or not the S21 is worth the upgrade for you personally depends on your specific needs and preferences. If you’re happy with your S7 and don’t feel like you’re missing out on any crucial features, you might not need to upgrade just yet. But if you’re looking for a device that can keep up with the latest trends and offer better performance, the S21 is a solid choice.

These differences may not be deal-breakers for everyone, but they’re certainly worth considering when deciding whether to upgrade.
Will I be able to use all the S21’s features with my existing accessories?
If you’re planning to upgrade from the S7 to the S21, you might be wondering if you’ll be able to use your existing accessories. The good news is that many of your existing accessories, such as headphones, cases, and chargers, should still be compatible with the S21. However, you might need to upgrade your charging cable to take advantage of the S21’s faster charging capabilities.
It’s also worth noting that the S21 uses a newer USB-C port instead of the older micro-USB port found on the S7. This means you might need to invest in some new cables or adapters to connect your old accessories to your new device. But overall, you should be able to use most of your existing accessories with minimal hassle.
How much will it cost to upgrade from the S7 to S21?
The cost of upgrading from the S7 to the S21 will depend on several factors, including your carrier, storage options, and whether you’re eligible for an upgrade or trade-in program. Generally speaking, you can expect to pay anywhere from $700 to $1,000 or more for the S21, depending on the model you choose.
If you’re due for an upgrade, you might be able to get a discount from your carrier or take advantage of a trade-in program to reduce the cost. Additionally, some retailers may offer promotions or discounts that can help bring the price down. Be sure to shop around and compare prices to find the best deal for your needs and budget.
Will I be able to transfer my data from the S7 to the S21?
Transferring your data from the S7 to the S21 is a relatively straightforward process. You can use Samsung’s Smart Switch software to transfer your contacts, photos, and other data from your old device to your new one. You can also use the Smart Switch app to transfer data from your S7 to the S21 wirelessly, making the process even easier.
Additionally, you can use other methods like Google Drive or iCloud to back up your data and then restore it to your new device. It’s always a good idea to back up your data regularly, so you should be able to transfer your important files and settings to your new device with minimal hassle.
Is the S21’s battery life better than the S7’s?
The S21’s battery life is indeed better than the S7’s. The S21 has a larger 4500mAh battery, which provides all-day battery life and then some. Additionally, the S21’s more efficient processor and software help to prolong battery life, so you can expect to get even more use out of your device between charges.
The S7, on the other hand, has a smaller 3000mAh battery, which may not provide the same level of battery life. If you’re looking for a device that can keep up with your busy lifestyle, the S21’s improved battery life is definitely worth considering.
Should I wait for the next Samsung flagship release instead of upgrading to the S21?
Whether or not you should wait for the next Samsung flagship release instead of upgrading to the S21 depends on your specific needs and preferences. If you’re due for an upgrade and the S21 meets your needs, there’s no reason to wait. The S21 is a solid device that offers a lot of great features and improvements over the S7.
However, if you’re not in a hurry and you’re willing to wait, you might be able to take advantage of even more advanced features and technologies when the next flagship release comes out. It’s always a good idea to weigh your options and consider your needs before making a decision.
