Samsung Galaxy S23 Series Replacement Batteries

Why Your Galaxy S23 Battery Matters

Every Galaxy S23 runs on a lithium-ion battery, and like any battery, it wears down with age and use. Now that the S23 series has been around for a couple of years, it's normal for the original battery to hold less charge than it did on day one, especially if you game, navigate, or stream often.

Before you assume the worst, it's worth ruling out a software cause first. If a recent update left your phone draining unusually fast, try optimizing background apps or checking battery health in your device's settings. But if you're seeing the signs below even after that, the battery itself is likely the problem:

• Your phone drains much faster than it used to, even with light use
• It shuts off unexpectedly, even with 20% or more showing on the screen
• The back of the phone feels warm, or the case looks slightly puffed out (a sign of a swollen battery)
• Your phone only stays powered on while plugged in
• Battery health readings in your phone's settings show it as weak or degraded

If any of that sounds familiar, a new battery is usually all it takes to get your S23 back to lasting a full day again.

Choosing the Right Battery for Your Galaxy S23

The Galaxy S23 series includes four different phones, and each one takes its own specific battery. The S23, S23+, S23 Ultra, and S23 FE are not interchangeable, so it's worth double-checking your exact model before you order.

• Galaxy S23: fits SM-S911 series models
• Galaxy S23+: fits SM-S916 series models
• Galaxy S23 Ultra: fits SM-S918 series models
• Galaxy S23 FE: fits SM-S711 series models

You can find your exact model number in your phone's Settings under About Phone, or printed on the original box. Every battery on this page is cross-referenced against Samsung's OEM part numbers, so if you're not sure, just match the model number on your phone to the compatibility list on each product page.

Once you've got the right battery, we also carry a few things to make the swap easier:

• A battery installation toolkit with everything needed to safely open your phone and remove the old battery
• A charging brick to get your S23 back up to full power once the new battery is installed
• A charging cable to go with it

Installing Your Replacement Battery

Replacing a Galaxy S23 battery at home is a manageable project if you take your time and use the right tools. Let your phone's battery drain below 25% before you start, since a fully charged lithium-ion battery is more sensitive to damage while it's being handled. Power off the phone completely and disconnect any cables first.

Keep in mind that opening the back cover will break the seal that gives your S23 its water resistance rating, so the adhesive needs to be reapplied carefully during reassembly. After installing your new battery, it's a good idea to fully charge it to 100%, let it drain completely, then charge it back up again. This helps your phone accurately read the new battery's charge level going forward. If you'd rather not tackle it yourself, a local phone repair shop can install the battery for you using the same part.

Frequently Asked Questions

How do I know which S23 battery is compatible with my phone?

A: Check your phone's exact model number in Settings under About Phone, then match it against the compatibility list on each battery's product page. The S23, S23+, S23 Ultra, and S23 FE each use a different battery, so the model number is the fastest way to confirm you're ordering the right one.

Is my battery actually bad, or is it a software issue?

A: Both are common on the S23 series at this point. Start by checking your phone's battery health in settings and optimizing background apps, since some software updates can cause temporary drain. If your battery health shows as weak, or the drain continues after optimizing, the physical battery is likely due for a replacement.

Do I need special tools to install a Galaxy S23 replacement battery?

A: Yes, most S23 batteries are held in place with adhesive, so you'll need a few basic tools like a suction handle, prying tools, and heat to safely remove the back cover. We offer a battery installation toolkit designed for this exact job, so you're not stuck hunting down tools separately.

Will replacing my own battery affect my phone's water resistance or warranty?

A: Opening your Galaxy S23 to replace the battery will break the factory seal, which can reduce its water resistance until the adhesive is properly reapplied. If your phone is still under Samsung's warranty, opening it yourself may void that coverage, so check your warranty status before starting a DIY repair.

Can I return my battery if it doesn't fit my phone?

A: Yes, Battery Mart accepts returns within 60 days of purchase. If you order the wrong battery for your S23 model, just reach out through our contact us page or check our returns policy for the full details.
