Samsung Galaxy S25 FE Battery Replacement Vienna
100 percent in the morning, in the red by lunchtime, or the S25 FE simply shuts down at 20 percent? Then the battery has worn. In Vienna Reparo fits a new 4,900 mAh battery for a fixed EUR 89, usually in one to two hours. Six months of warranty come with it; we collect in Vienna, you post it from the provinces or drop it off by appointment.
Samsung S25 FE battery replacement: cost and what you get
A new battery for the Samsung Galaxy S25 FE costs EUR 89 at Reparo in Vienna. That includes a 4,900 mAh battery as from the factory, opening and resealing the glass back, and a test of 45-watt fast charging and wireless charging. We use an original battery or a tested replacement battery with the same capacity. Six months of warranty are included, and the EUR 25 diagnostic check is waived.
Galaxy S25 FE battery replacement
4,900 mAh battery including fitting
- New battery with 4,900 mAh
- Glass back resealed with a fresh gasket
- Test of 45 W cable charging and wireless charging
- Check of battery status and temperature while charging
- 6-month warranty on battery and fitting
Diagnostic check 25 EUR, waived on repair. We dispose of the old battery properly.
Signs of a tired battery in the S25 FE
- The battery drops from 30 percent to zero and the phone switches off
- The S25 FE gets unusually hot while charging or gaming
- The battery no longer lasts from morning to evening
- Samsung Members shows the battery status as “Weak”
- The back bulges slightly or gapes at the edge
A bulging back is a warning sign: the battery is swelling and pushing the glass outwards. In that case stop charging the S25 FE and bring it to us soon. You can check the battery status yourself in the Samsung Members app under Phone diagnostics. Whatever else can be fixed on the phone is shown in the Galaxy S25 FE overview.
Galaxy S25 FE battery swap step by step
On the Galaxy S25 FE the battery sits behind the bonded glass back. We warm the back, lift it off carefully, disconnect the old battery and release it from its adhesive bed. The new 4,900 mAh battery is glued in and connected, and the back is sealed with a new gasket. Then we test charging by cable and wirelessly. Allow one to two hours of workshop time.
- Measure battery status
We read out condition and charging behaviour to be sure the battery really is to blame and not the charging port.
- Remove the back
With heat and flat tools we release the glass without breaking it.
- Swap the battery
Disconnect the old battery and free it from the adhesive, glue in the new battery and connect it.
- Seal and charge
Stick the back on with a fresh gasket, then check 45-watt cable charging, wireless charging and temperature.
If you want to hand over the S25 FE yourself, book an appointment in the 22nd district; in Vienna we can also collect it.
A battery for EUR 89 or a new S25 FE?
A battery loses some capacity with every charge cycle, however new the phone is. On the S25 FE, on sale since September 2025 and due to get updates for years, a swap is the cheapest way to get the full runtime back. A new S25 FE cost EUR 749 at launch in the 128 GB version.
| Battery replacement at Reparo | New Galaxy S25 FE | |
|---|---|---|
| Cost | EUR 89 | RRP EUR 749 (128 GB, launch 2025) |
| Capacity | new battery with 4,900 mAh | 4,900 mAh |
| Data | stays on the phone | migration needed |
| Duration | 1–2 hours | purchase and set-up |
Reference value: Samsung recommended retail price at launch in September 2025.
If the S25 FE only charges while you wiggle the plug, it is not the battery but the port. We replace that for EUR 69: S25 FE charging port repair. We measure beforehand which part is at fault.
4,900 mAh, 45 watts and wireless charging
The S25 FE has a 4,900 mAh battery, 200 mAh more than the S24 FE. By cable it charges at up to 45 watts, wirelessly at up to 15 watts, and it can power other devices such as earbuds by reverse wireless charging. After the swap we test all three, so that no function is missing after the repair.
How many charge cycles before the S25 FE battery fades?
How many hours it is depends heavily on brightness, mobile data and gaming. After a few hundred charge cycles you usually notice a clear drop. At the latest when Samsung Members shows the status “Weak” or the phone switches off at double-digit percentages, a swap makes sense.
Making the new battery last longer
In the battery settings there is Battery protection, which can stop charging at 80 percent. If your S25 FE spends nights or long drives on the cable, this spares the cell. It also helps not to leave the phone in the sun while charging and not to run it down to zero all the time.
Frequently asked questions about the Galaxy S25 FE battery replacement
Samsung Galaxy S25 FE battery replacement – what is included in EUR 89?
A new battery with 4,900 mAh, releasing and resealing the bonded glass back, and a test of 45-watt cable charging, 15-watt wireless charging and reverse charging. Six months of warranty on battery and fitting are included, and the EUR 25 diagnostic check is dropped once you order the swap.
Samsung S25 FE battery draining fast – is it the battery?
Not always. Sometimes an app eats power in the background or the screen runs at full brightness all the time. Check under Battery in Settings what uses the most. If nothing stands out there and Samsung Members reports a weak battery status, a new battery for EUR 89 brings the runtime back.
What battery capacity does the Samsung Galaxy S25 FE have?
4,900 mAh. That is 200 mAh more than the Galaxy S24 FE with 4,700 mAh. When replacing it we fit a battery with exactly this capacity again, not a smaller one. How long it lasts in daily use then depends mainly on how bright the screen is and how much you stream or game.
How long does a Galaxy S25 FE last on a full battery?
With a healthy battery most people get comfortably through a whole day; with lots of navigation, video or gaming it gets tight in the evening. If your S25 FE only lasts half a day although you use it no differently than before, the battery has aged. Then a swap for EUR 89 is worth it.
Does the S25 FE charge at 45 watts again after the battery swap?
Yes, provided your charger delivers 45 watts. The new battery does not limit fast charging. After fitting we test with a 45-watt charger and watch whether the phone gets unusually warm. With an older 25-watt charger the S25 FE charges more slowly, which is not a fault.
What makes my S25 FE shut down suddenly at 20 percent?
Usually a worn battery. Under load the voltage drops and the phone switches off to protect itself, even though percentages are still shown. A new battery for EUR 89 fixes this. If it happens again shortly after the swap, we also check the logic board under the warranty.
Does the S25 FE still charge on a pad and power earbuds after the battery swap?
Yes. The coil for wireless charging stays in the phone; after the back is resealed we put the S25 FE on a pad to check charging at up to 15 watts and test reverse charging with earbuds or a watch. If either fails, we notice it before the handover and sort it out first.
Can I drop off the S25 FE for a battery swap myself?
Yes, by appointment. If you book drop-off online, you get a fixed time window in the 22nd district in which someone receives the S25 FE. Turning up without a booking does not work, because otherwise nobody is on site. As soon as the new battery is in and tested, we get in touch.
Do you collect an S25 FE with a weak battery in Vienna?
Yes, and with a battery problem that is handy, because you do not have to cross town with a dying phone. We collect the S25 FE in the chosen time window and bring it back with a new 4,900 mAh battery. Pickup and return delivery cost from EUR 17.90 depending on the zone, and the form shows the amount before you send it.
Is a swollen S25 FE battery safe to send by post?
Please not without talking to us first. Damaged lithium batteries are not allowed in the post, and a swollen battery counts as damaged. Call us in that case; in Vienna we collect the phone, or you drop it off by appointment. A normally aged battery without bulging can be sent in as usual.
Do photos and apps stay on the S25 FE during a battery swap?
Yes. The battery only supplies power; data is stored on a separate chip on the logic board. After the swap your S25 FE starts with all photos, chats and apps exactly as before. We do not need to reset anything, and a backup is not strictly necessary for this job.
Does my S25 FE get an original battery or a copy?
An original Samsung battery or a tested replacement battery with the same 4,900 mAh, depending on what is available. We tell you which one before fitting. We do not fit cheap batteries with inflated capacity claims, because they often fade after a short time.
What happens if the new S25 FE battery weakens early?
Tell us, because battery and fitting carry six months of warranty from us. Should the S25 FE lose charge unusually fast or shut down at 15 or 20 percent again, we measure the cell and swap it at no charge. A drop or liquid in the phone voids that cover. Hold on to the invoice as proof.
Is a new battery worth it in a phone as young as the S25 FE?
Yes, precisely because of that. The S25 FE has been available since September 2025 and will get Android updates for a long time. If only the battery is fading, the rest of the phone is almost new. For EUR 89 you get the full runtime back instead of spending around EUR 749 on a new S25 FE at launch price.
Could the battery be affected if my S25 FE got wet?
The battery itself is sealed, but water inside the phone attacks its connectors and the charging electronics. Afterwards it sometimes drains overnight or the S25 FE stops charging altogether. With water damage we first clean the phone in a bath for around 48 hours and only decide after the findings whether the battery needs replacing.
