Galaxy S10 Battery Replacement: Cost & DIY Guide
A Galaxy S10 battery replacement costs about $12 to $30 for the part if you do it yourself, or roughly $50 to $90 at a repair shop. It is absolutely a DIY-doable job with a heat source, a few pry tools, and about an hour of patience. Given the S10 launched in March 2019, most units still in service are running on a battery that has cycled well past its healthy lifespan, so a fresh cell is usually the single best upgrade you can make.
Below is everything you need to decide whether to swap the 3400mAh cell yourself, hand it to a shop, or keep the phone running for another two or three years instead of replacing it.
Why your Galaxy S10 battery is failing (it's mostly age)
Lithium-ion cells lose capacity every charge cycle. Samsung rates the S10 pack for roughly 500 full cycles before it drops to about 80% of its original 3400mAh. If you bought your S10 new, you are likely five or more years and well over a thousand cycles in. That is the real reason your afternoon battery anxiety is worse than it used to be, not a rogue app or a bad update.
Common symptoms owners report at this stage:
- The phone dies by mid-afternoon on a charge that used to last all day.
- It shuts off suddenly at 20-30% remaining, especially in cold weather.
- Charging feels slower, or the phone runs hot while topping up.
- The back glass or screen feels like it is bulging — a sign of a swollen battery.
How to check your Galaxy S10 battery health
On newer Samsung phones running One UI 5 or later, you can see a native battery health percentage under Settings → Battery and device care → Battery → Diagnostics → Battery health. The catch: the S10 topped out at Android 12 / One UI 4.1 and never received that battery-health readout, so you will not find a true percentage in its menus.
Honest workaround: install a free app like AccuBattery. It estimates real-world capacity by measuring current draw across several charge cycles. Do not trust the first reading — give it three or four full charges before you treat the number as meaningful. If it estimates your S10 is holding 2400mAh or less against the 3400mAh spec, you have your answer.
You can also run Samsung Members → Get help → Interactive checks → Battery for a quick "Good/Bad" status flag, though it is far less granular than an actual percentage.
Signs your Galaxy S10 battery is failing
If you searched because your Galaxy S10 battery is draining fast, watch for the pattern rather than a single bad day. A dying cell drains fast, charges unevenly, and drops voltage under load — which is why the phone can read 30% and then die when you open the camera.
Safety note on swelling: if the back glass is lifting, the screen is pushing up at an edge, or the phone rocks on a flat table, stop charging it immediately. A swollen lithium pouch is a fire and rupture risk. Do not puncture it, do not press on it, and replace it promptly. On a curved-glass phone like the S10, a swelling battery can crack the display from the inside, so acting early saves the screen too.
Galaxy S10 battery replacement cost in 2026
Here is the realistic price picture. Samsung's own out-of-warranty service for a device this old is limited and, where still offered, is the most expensive route. A local shop is the middle option. DIY is by far the cheapest.
| Option | What you get | 2026 price |
|---|---|---|
| Manufacturer / authorized service | Genuine cell, labor, limited on older models | $60-99 (if available) |
| Local repair shop | Part + labor, done same day | $50-90 |
| DIY with a quality replacement battery | The cell, adhesive, and tools | $12-30 + tools |
Searching "galaxy s10 battery replacement near me" will usually surface shops in the $50-90 band. Most of that is labor. If you are comfortable opening the phone, the DIY route keeps a working flagship alive for the price of a takeout dinner.
The exact replacement battery for the Galaxy S10
The Galaxy S10 uses a 3400mAh lithium-polymer cell, Samsung part number EB-BG973ABU. It fits every S10 variant — sold as SM-G973, SM-G9730, SM-G973F, SM-G973N, SM-G973U, and SM-G973U1. Do not confuse it with the larger 4100mAh S10+ cell (EB-BG975ABU) or the smaller 3100mAh S10e cell; they are physically different and will not seat correctly.
When shopping for a galaxy s10 oem battery, look for the correct EB-BG973ABU part number, the matching 3.85V nominal / 3400mAh rating, and ideally a zero-cycle or genuine-pull cell rather than an unbranded no-name pack.

How to replace a Galaxy S10 battery yourself
Here is the honest difficulty rating: moderate to hard, about 6 out of 10. The S10 opens from the back through glued glass, and the battery itself sits under stubborn adhesive. Nothing here is beyond a careful first-timer, but rushing it cracks glass. Budget 45-75 minutes.
What the job looks like at a high level:
- Power down and heat the back. Warm the rear glass with a heat pad or hair dryer to soften the perimeter adhesive, then work a thin suction cup and pry tool around the edge to lift the back panel. Mind the fingerprint sensor cable.
- Remove the shields. Unscrew the plastic charging-coil bracket and the lower board bracket to expose the battery connector.
- Disconnect the battery first. Always unplug the battery connector before touching anything else.
- Free the old cell. Apply a few drops of isopropyl alcohol or use adhesive-remover strips, then lift gently and evenly. Never pry against or fold a battery.
- Fit the new 3400mAh cell, reconnect, reassemble, and re-seal the back glass with fresh adhesive.
Tools you will want: a heat source, a suction cup, plastic spudgers/opening picks, a Phillips #00 driver, tweezers, replacement back-glass adhesive, and isopropyl alcohol. A prep kit and a step-by-step teardown are worth having open before you start. For a broader walkthrough across models, see our phone battery replacement by model guide.
After the swap: calibrate the battery
Samsung phones do not throw an "unauthorized part" lockout the way an iPhone does, so your S10 will simply boot and work. You may occasionally see a generic notification that a non-genuine component was detected — it is informational and does not disable the phone.
To get an accurate battery gauge on a fresh cell, run one calibration cycle: charge to 100%, keep charging for another half hour, then use the phone normally until it shuts off on its own, and finally charge uninterrupted back to 100%. This resyncs the software fuel gauge with the new cell's true capacity so your percentage readout stops jumping around. One clean cycle is usually enough.
Repair vs. upgrade: is a Galaxy S10 still worth it?
A new mid-range phone starts around $400, and a comparable flagship is far more. A $12-30 battery restores the single thing that actually degraded on your S10 — the display, cameras, and processor are all still perfectly capable for messaging, browsing, and photos. Spending $20 to get another two or three years out of a phone you already own is the clear financial win.
It is the environmental win too. Manufacturing one new smartphone generates roughly 60kg of CO2 and pulls fresh rare-earth metals out of the ground. Keeping your S10 alive with a new cell is exactly the "repair, don't replace" choice that keeps a working device out of the e-waste stream. If the rest of the phone is sound, a battery is almost always the smarter money.
FAQ
How much does a Galaxy S10 battery replacement cost?
Expect $12-30 for the battery if you do it yourself, or $50-90 at a repair shop where most of the cost is labor. Manufacturer service, where still offered for a phone this old, runs $60-99.
How do I replace a Galaxy S10 battery?
Power down, heat the back glass to release the adhesive, lift the rear panel with a suction cup, remove the internal brackets, disconnect the battery connector first, free the old 3400mAh cell with isopropyl alcohol, fit the new EB-BG973ABU battery, and reseal with fresh adhesive. Plan on 45-75 minutes.
Why is my Galaxy S10 battery draining fast?
After five-plus years and hundreds of charge cycles, the original 3400mAh cell has lost a large share of its capacity. That is normal age-related degradation, and a new battery restores runtime far more effectively than tweaking settings.
Does the Galaxy S10 show battery health like an iPhone?
No. The S10 never received Samsung's native battery-health percentage (that arrived in One UI 5, and the S10 stopped at One UI 4.1). Use a free app like AccuBattery, and give it several charge cycles before trusting the estimate.
What is the correct OEM battery for the Galaxy S10?
The genuine part is the 3400mAh EB-BG973ABU, which fits all SM-G973 variants. Avoid the larger S10+ (EB-BG975ABU) and smaller S10e cells — they will not fit correctly.
Is my Galaxy S10 battery swollen, and is that dangerous?
If the back glass or screen is lifting or the phone rocks on a flat surface, the battery is likely swollen. Stop charging it, do not puncture it, and replace it promptly — a swollen lithium cell is a fire risk and can crack the display from inside.
