Is It Worth Replacing Your Samsung Galaxy S8 Battery In 2023?

If your Samsung Galaxy S8 is still going strong in 2023 but the battery life is starting to let you down, you may be wondering whether it’s worth replacing the battery.

With phones lasting longer these days thanks to software updates and advances in hardware durability, replacing an aging battery can breathe new life into an otherwise still-capable device.

If you’re short on time, here’s a quick answer: Replacing your Galaxy S8 battery can definitely be worth it if the phone is still meeting your needs. A new battery can make the S8 feel like new again, and is a lot cheaper than upgrading to a whole new phone.

In this detailed guide, we’ll look at the pros and cons of replacing an S8 battery in 2023, what’s involved in the replacement process, how much it costs, which replacement batteries to choose from, and some other options beyond replacing the battery.

The Pros of Replacing an S8 Battery

Extend the usable life of your phone

One of the biggest advantages of replacing your Samsung Galaxy S8 battery is that you can extend the usable life of your phone.

Over time, smartphone batteries tend to degrade and lose their capacity to hold a charge. By replacing the battery, you can potentially add another year or two to the life of your device, saving you from having to invest in a new phone.

Improve battery lifespan and performance

Replacing the battery in your S8 can also help improve its overall battery lifespan and performance.

A new battery can provide better battery life, allowing you to use your phone for longer periods without having to constantly recharge. Additionally, it can help prevent unexpected shutdowns or issues with battery drainage, ensuring a smoother and more reliable user experience.

Cheaper than buying a new phone

When considering whether to replace your S8 battery or buy a new phone, cost is a crucial factor.

Replacing the battery is generally much cheaper than purchasing a brand new device. The cost of a new battery is often a fraction of the price of a new phone, making it a cost-effective solution to improve the performance of your S8 without breaking the bank.

Fairly easy and inexpensive to replace

Replacing the battery in a Samsung Galaxy S8 is a relatively simple process.

Many mobile repair shops and authorized service centers offer battery replacement services, and you can even find DIY battery replacement kits online. With a little bit of research and guidance, you can replace the battery yourself, saving both time and money.

Keep all your data, apps, and settings

One of the greatest advantages of replacing your S8 battery is that you can keep all your data, apps, and settings intact.

Unlike purchasing a new phone, where you have to transfer everything from your old device, replacing the battery allows you to continue using your phone with all your personalized settings, apps, and important data without any disruption.

The Cons of Replacing an S8 Battery

The S8 is now a 6-year-old phone

One major drawback of replacing the battery on your Samsung Galaxy S8 is that the phone itself is now six years old.

Technology has advanced significantly since its release, and newer models offer a range of improvements and features that the S8 simply can’t compete with. While replacing the battery may give your phone a temporary boost, it won’t address the underlying issue of outdated hardware.

You’ll eventually need to replace again down the line

Replacing the battery in your Samsung Galaxy S8 may seem like a cost-effective solution in the short term, but it’s important to consider the long-term implications.

Batteries have a limited lifespan, and even with a replacement, you’ll likely find yourself needing to replace it again in the future. This can be both a hassle and an additional expense that you may not want to deal with.

Newer phones have better specs and features

One of the main reasons people choose to replace their phone’s battery is to extend its lifespan. However, it’s worth considering whether investing in a battery replacement for an older phone is the best use of your money.

Newer phones on the market offer improved specs, better camera capabilities, and more advanced features. Instead of spending money on a battery replacement, you might want to consider upgrading to a newer model that will give you a better overall experience.

Potential issues with getting a faulty replacement battery

When replacing the battery in your Samsung Galaxy S8, there is always a risk of getting a faulty replacement. This can lead to issues such as poor battery life, overheating, or even damage to your phone.

It’s important to purchase replacement batteries from reputable sources and ensure they are compatible with your specific model. Taking this risk into account is essential before deciding to replace the battery.

It’s time-consuming to replace yourself

Replacing the battery in your Samsung Galaxy S8 is not a simple task. It requires technical knowledge, specialized tools, and a significant amount of time.

If you’re not experienced with phone repairs, attempting to replace the battery yourself could lead to further damage or even render your phone unusable. Considering the time and effort involved, it may be more practical to seek professional help or explore other options for extending the life of your device.

What’s Involved in Replacing the Battery

If you’re considering replacing the battery in your Samsung Galaxy S8 in 2023, it’s important to understand the process involved. Here’s a breakdown of the steps you’ll need to take:

Order a replacement battery online

The first step in replacing your Samsung Galaxy S8 battery is to order a replacement battery online.

There are many reputable websites where you can purchase genuine Samsung batteries. Make sure to choose the correct model and check customer reviews before making a purchase.

Use a heat gun to soften glue (optional)

Once you have the replacement battery, you may need to use a heat gun to soften the adhesive glue that holds the back cover in place.

This step is optional, as some replacement batteries come with pre-applied adhesive. However, if your battery doesn’t include adhesive, using a heat gun can make the removal process easier.

Open up the phone to access the battery

Next, you’ll need to open up your Samsung Galaxy S8 to access the battery.

This can be done by removing the screws on the back cover and carefully prying it off. Be sure to use the right tools and take your time to avoid causing any damage.

Disconnect and remove the old battery

Once you have access to the battery, you’ll need to disconnect it from the phone’s motherboard and carefully remove it.

Take note of how the old battery is connected so you can easily reconnect the new one later.

Install the new battery and reconnect

Now it’s time to install the new battery.

Gently place it in the same position as the old battery and reconnect it to the motherboard. Double-check that all connections are secure before proceeding.

Close up the phone and test it out

Finally, you’ll need to close up the phone by reattaching the back cover and tightening the screws. Once everything is in place, turn on your Samsung Galaxy S8 and make sure it powers up without any issues.

If everything looks good, congratulations! You’ve successfully replaced your battery.

Remember, if you’re not confident in your ability to replace the battery yourself, it’s always best to seek professional help. There are many reputable phone repair shops that can assist you with the process.

Cost of Replacing an S8 Battery

When considering whether to replace the battery in your Samsung Galaxy S8, one of the most important factors to consider is the cost. Here, we break down the various expenses associated with battery replacement.

Replacement batteries can cost $15-$50

If you are tech-savvy and confident in your abilities to replace the battery yourself, you can find replacement batteries for the Samsung Galaxy S8 online for as low as $15.

However, it is important to note that cheaper batteries may not offer the same level of performance and reliability as more expensive ones. It is recommended to opt for higher-quality replacement batteries, which typically range from $30 to $50.

Pay a repair shop $50-$100 for labor

If you prefer to have a professional handle the battery replacement process, you can take your Samsung Galaxy S8 to a repair shop.

The labor cost for this service can vary depending on the location and the reputation of the shop. On average, you can expect to pay around $50 to $100 for the labor involved in replacing the battery.

Consider extra costs like tools and shipping

When replacing the battery yourself, it is important to consider the additional costs that may be involved.

You may need to purchase specialized tools, such as a small screwdriver or a prying tool, to safely open your device and replace the battery. Additionally, if you choose to order a replacement battery online, you may need to factor in shipping costs.

Weigh cost vs buying a new budget phone

Before deciding to replace the battery in your Samsung Galaxy S8, it is worth considering whether it would be more cost-effective to invest in a new budget phone.

As technology advances, newer models offer improved performance and features at affordable prices. Take into account your specific needs and budget to determine whether the cost of replacing the battery outweighs the benefits of purchasing a new device.

Choosing the Best Replacement Battery

Stick with reputable brands like iFixit

When it comes to replacing your Samsung Galaxy S8 battery, it’s important to stick with reputable brands like iFixit.

These brands are known for their high-quality replacement batteries that are specifically designed to fit your device.

Ensure it’s designed specifically for the S8

Make sure that the replacement battery you choose is specifically designed for the Samsung Galaxy S8.

Using a battery that is not compatible with your device can lead to performance issues and even potential damage.

Check battery health ratings and reviews

Before making a purchase, it’s a good idea to check the battery health ratings and reviews of the replacement battery.

This will give you an idea of how well the battery performs and how long it is likely to last.

Aim for OEM-grade quality and performance

While there are many aftermarket replacement batteries available, it’s best to aim for OEM-grade quality and performance.

These batteries are designed to meet the same standards as the original battery that came with your Samsung Galaxy S8.

Consider battery warranty and return policy

Lastly, consider the battery warranty and return policy offered by the manufacturer.

A reputable brand will typically offer a warranty period and a fair return policy, giving you peace of mind in case you encounter any issues with the battery.


At the end of the day, replacing an aging battery can give your Galaxy S8 a new lease on life at a fraction of the cost of a brand new phone. Just make sure to do your research and choose a quality replacement battery from a reputable source.

If you’ve been otherwise happy with your S8 and the phone is still performing well aside from poor battery life, taking the battery replacement route lets you keep a device you’re already comfortable with while improving its performance.

Just weigh the time and effort involved against simply upgrading to a newer budget phone before making your decision.
