Galaxy S10 Plus Battery Replacement: Cost & DIY
A Galaxy S10 Plus battery replacement costs about $50 to $90 at a repair shop, or $15 to $30 if you buy the 4100mAh cell and fit it yourself. Released in early 2019, the S10+ is now well past the point where its original battery holds a full day's charge, and a new cell is by far the cheapest way to keep this still-capable phone in service.
This guide walks through how to confirm the battery is the problem on an older phone like this, the exact part you need, the DIY process, and whether the repair is worth it against buying something new.
How to check your Galaxy S10 Plus battery health
Here's an honest heads-up for S10 Plus owners: your phone likely won't show a built-in battery health readout. Samsung added the Settings → Battery and device care → Battery → Diagnostics → Battery health report in One UI 5, but the S10 line's final software was One UI 4.1. Newer Galaxy phones have that menu; the S10+ generally does not.
So instead of chasing a menu that isn't there, measure the battery directly. Install a free app like AccuBattery, then use the phone normally for several charge cycles. AccuBattery estimates real-world capacity against the factory 4100mAh rating. On a six-year-old S10 Plus, it's common to see measured capacity down in the low 3,000mAh range or worse, and that number tells you plainly why your Galaxy S10 Plus battery life has collapsed.
You can also watch the discharge graph under Settings → Battery. A worn cell drops in steep steps and tends to fall off a cliff in the last quarter of the charge.
Signs your Galaxy S10 Plus battery is failing
On a phone this age, battery wear is usually the loudest symptom. Look for:
- The battery draining fast even when the phone is idle.
- Random shutdowns at 20 to 40 percent, especially in cold weather.
- Screen-on time down from a full day to just a few hours.
- The phone running warm during light tasks or while charging.
- Slow, erratic, or stalled charging.
- A back panel that bulges, or a screen edge that has started to lift.
That last symptom is a safety issue and it's more common on older phones. A swollen lithium-ion battery is expanding and pushing the case apart. Stop charging and using the phone, power it down, keep it away from heat, and never puncture or bend the swollen cell. Take it to a battery or e-waste recycling point for disposal. On a device the age of the S10+, a swelling battery is a clear signal to replace it now rather than later.
Galaxy S10 Plus battery replacement cost
Here's what the three routes cost in 2026. Because the S10+ is out of the standard support window, authorized service is less commonly offered, so most people use an independent shop or do it themselves.
| Option | Typical 2026 price | What you get |
|---|---|---|
| Samsung / authorized service | $70 - $90 (if offered) | Genuine part and labor, subject to parts availability on an older model |
| Local / independent repair shop | $50 - $85 | Aftermarket or OEM-pull cell, usually same-day |
| DIY with a quality replacement battery | $15 - $30 (part) | The 4100mAh cell plus adhesive; your own tools and time |
As with any battery job, the gap between the shop price and the DIY Galaxy S10 Plus battery replacement cost is almost entirely labor. If you already own a pry kit and a heat source, the repair costs little more than the price of the cell itself.
The exact replacement battery for the Galaxy S10 Plus
The Galaxy S10 Plus uses a 4100mAh lithium-ion battery, Samsung part number EB-BG975ABU. It fits every S10+ variant sold under model number SM-G975, including SM-G975F, SM-G975U, SM-G975U1, SM-G975N, SM-G975W, and SM-G975UC. Confirm your model under Settings → About phone, or on the SIM tray, before ordering.
Don't confuse the S10+ cell with the smaller batteries in the standard S10 (3400mAh) or the S10e (3100mAh). They're different parts and aren't interchangeable. When you shop for a Galaxy S10 Plus OEM battery or a quality aftermarket equivalent, match the EB-BG975ABU number and the 4100mAh rating. Ours is listed on our Galaxy S10 Plus battery product page, and you can compare it with other Samsung cells in our replacement batteries collection, both priced for single repairs and wholesale volume.
Replacing the Galaxy S10 Plus battery yourself
The S10 Plus is a glass-backed phone, so the repair begins at the rear panel. Here's the overview of how to replace a Galaxy S10 Plus battery:
- Power off the phone and warm the back glass to soften the perimeter adhesive. A heat pad or hair dryer does the job.
- Lift the back cover with a suction cup and thin pick, working slowly. Watch for the wireless-charging and flex cables attached to the panel.
- Remove the plastic wireless-charging coil bracket (small Phillips screws) to expose the battery.
- Release the battery adhesive with a plastic pry tool; a little isopropyl alcohol under the edges helps. Never use a metal tool against the cell and never bend it, especially if it has begun to swell.
- Seat the new 4100mAh battery, apply fresh adhesive, reconnect the cables, and reseal the back panel with new adhesive.
Honest difficulty rating: moderate, about a 6 out of 10. The back-glass removal is the delicate part, and years of heat cycling can make the original battery adhesive stubborn, so be patient and add heat rather than force. Take extra care around the under-display ultrasonic fingerprint sensor and its flex cable. Budget an hour, and replace the perimeter adhesive fully if you want to preserve water resistance.
After the swap: calibrate the battery
Samsung won't lock the phone or disable any features after a battery swap. If you install an aftermarket cell you may see a one-time notice that a non-genuine battery was detected, but that's purely informational and the battery works normally.
Do run a calibration cycle so the software reads the new cell correctly, which matters more on an older phone where the old fuel-gauge data is well out of date. Charge to 100 percent and leave it plugged in a few extra minutes. Then use the phone until it powers off on its own from empty. Finally, charge uninterrupted back to a full 100 percent. That single deep cycle re-syncs the capacity estimate with the fresh 4100mAh battery and usually clears up any strange percentage jumps in the first day.
Repair vs. upgrade: is a new battery worth it?
A $15 to $30 battery to revive a phone that would cost hundreds to replace is an easy call. The S10 Plus still has a beautiful QHD+ display, a flexible triple-camera system, a headphone jack, and expandable storage, and it remains perfectly fast for messaging, browsing, streaming, and navigation. In almost every case the tired battery is the one thing holding it back.
The environmental math is just as compelling. Most of a smartphone's lifetime carbon footprint is created during manufacturing, before the phone is ever powered on. Replacing a battery instead of buying new skips that entire upfront impact and keeps a working device out of the e-waste stream. That's the whole idea behind PhonePartPro: repair, don't replace, and keep devices alive and out of landfills. On a phone the age of the S10 Plus, a new battery is the single highest-value repair you can make.
If you're ready to do it yourself, grab the cell from our Galaxy S10 Plus battery page, and ask about wholesale pricing if you run a repair shop. For any other device, our full battery replacement by model guide covers the rest of the Galaxy and iPhone lineup.
FAQ
How much does a Galaxy S10 Plus battery replacement cost?
Expect $50 to $85 at an independent repair shop in 2026, or $70 to $90 at authorized service if parts are still available for this older model. Doing it yourself, the 4100mAh replacement battery costs about $15 to $30 plus adhesive and basic tools.
Why is my Galaxy S10 Plus battery draining fast?
The S10 Plus is now several years old, so its original 4100mAh cell has lost a large share of its capacity and can't hold a full day's charge. After ruling out background apps and high brightness, a big drop in screen-on time points to the battery itself.
How do I replace a Galaxy S10 Plus battery?
Heat and lift the back glass, remove the wireless-charging bracket, release the old battery adhesive with a plastic tool and a little isopropyl alcohol, then install the new 4100mAh cell with fresh adhesive and reassemble. It's a moderate repair, roughly an hour, with extra care around the fingerprint sensor flex.
What is the exact Galaxy S10 Plus battery?
It's a 4100mAh lithium-ion cell, Samsung part EB-BG975ABU, fitting every SM-G975 variant (SM-G975F, SM-G975U, SM-G975U1, SM-G975N, SM-G975W, SM-G975UC). It is not the same as the standard S10 or S10e battery.
How can I check my Galaxy S10 Plus battery health?
The S10 line's software stopped at One UI 4.1, which doesn't include Samsung's built-in battery health report, so that menu likely won't appear. Instead, install AccuBattery and measure real capacity against the 4100mAh factory rating over several charge cycles.
Should I calibrate the battery after replacing it?
Yes. Charge to 100 percent, use the phone until it powers off on its own, then charge uninterrupted back to 100 percent. This deep cycle re-syncs the fuel gauge with the new 4100mAh cell, which matters more on an older phone with outdated battery data.
