Typical battery problems on the Galaxy S23
- Your Galaxy S23 battery won't even make it through a working day – with the original cell you used to get 5–7 hours of screen-on time
- The phone shuts off suddenly at 20–30% remaining charge and only comes back on once you plug it in
- The 3900 mAh battery gets noticeably hot while charging or during 25W fast charging – a sign of chemical ageing
- The battery percentage jumps in steps of ten instead of dropping smoothly – the calibration is lost
- Wireless charging at 15W no longer works or charges only very slowly
- The case bulges around the battery area – visible battery swelling (the result of deep discharge)
- The Galaxy S23 won't start at all after a full discharge – the battery is deeply discharged and refuses to take a charge
The Galaxy S23 launched in 2023 with 3900 mAh (200 mAh more than the S22) – and exactly that cell ages noticeably after 2–3 years. Ignoring battery shutdowns risks deep discharge and permanent cell damage that can make a simple battery replacement impossible. See our Galaxy S23 repair overview for all the options.
How does the Galaxy S23 battery replacement work?
- Battery diagnosis via service mode
The Samsung service code *#0228# opens the battery status page. There we check the voltage, temperature and charge cycles of your Galaxy S23. A capacity under 80% or a cycle count above 500 justifies the replacement.
- Temperature-controlled removal of the display unit
Samsung S/A devices have the battery underneath the display – the OLED panel is warmed evenly to roughly 70 °C and released with flat carbon spudgers, without distorting the Armor Aluminum frame.
- Removing the old battery in a controlled way
The single battery cell is held to the case with adhesive. We loosen the glue with 99% isopropanol and fine pull tabs – never using screwdrivers as a lever. With swollen batteries: hazardous-goods disposal handled directly by Reparo.
- Fitting the certified battery cell
A single cell with 3900 mAh is connected to the original connector on the mainboard and fixed to the Armor Aluminum frame with Samsung adhesive. Polarity and contact pressure are checked – incorrect positioning costs 3% capacity.
- Display refit + IP68 seal renewal
The old adhesive film is fully removed, a new IP68 Samsung seal is applied, and the display is bonded back on under defined pressure. After 30 minutes of curing time the sealing values are restored.
- Full charge + calibration
A first charge to 100% at 25 °C room temperature – followed by a full discharge and another charge. This calibrates the battery gauge to the new cell's characteristics. You get your Galaxy S23 back with a precisely calibrated battery.
Reparo works without a walk-in – your Galaxy S23 is collected by courier in Vienna or sent in from the provinces in a hazardous-goods-compliant shipping box.
Galaxy S23 battery replacement – process, price and battery life in Vienna
The Samsung Li-Po battery in the Galaxy S23 has a capacity of 3900 mAh, built as a single cell. After 500 to 700 full cycles (usually 2–3 years of everyday use) the usable capacity drops below 80% – you notice it through sudden shutdowns between 20 and 30%, a hot case during 25W charging, or a visible bulge on the back. Our Galaxy S23 Plus shows similar symptoms, but the repair effort and price differ.
Reparo replaces the Galaxy S23 battery in Vienna for EUR 79 fixed price – roughly 9% of the original launch price (EUR 849). Included are certified 3900 mAh cells, a new IP68 seal, calibration and a 6-month warranty. If you also have screen cracks or touch problems, you save with a combined repair – see our separate S23 screen replacement for details.
Certified cell vs. original Samsung – what goes into the Galaxy S23?
For the Galaxy S23 we fit certified battery cells that match the original Samsung specifications: the same nominal voltage (3.85 V), the same 3900 mAh capacity, the same charge curve. Samsung service-pack cells are only available through authorised Samsung service centres. Our cells last measurably as long as the originals – 500 to 700 cycles with no significant capacity loss. You can see all the options in the price comparison on the Samsung repair overview.
Frequently asked questions about the Galaxy S23 battery replacement
How much does a battery replacement cost on the Galaxy S23?
The Galaxy S23 battery replacement is EUR 79 fixed price at Reparo in Vienna. The price includes a certified Samsung-compatible battery cell with 3900 mAh, a new IP68 seal, calibration and a 6-month warranty. The diagnosis (EUR 25) is waived when you go ahead with the repair.
How long does the new Galaxy S23 battery last?
With normal use the replacement battery lasts 500–700 full cycles while keeping at least 80% capacity – roughly 2.5 to 3.5 years of everyday use. One full cycle = a complete discharge from 100% to 0%. Partial charges count proportionally. The warranty runs for 6 months on the cell and the labour.
Is the 3900 mAh battery in the Galaxy S23 a standard replacement or an original?
We fit certified 3900 mAh battery cells that match the original Samsung specifications – the same voltage (3.85 V), the same capacity, the same form factor. Original Samsung service packs are only available through Samsung service centres and not accessible to independent workshops. Our replacement cells last measurably just as long.
Does the Galaxy S23 charge with 25W just as fast as before after the battery replacement?
Yes. The Galaxy S23 supports 25W charging via the USB-PD protocol – this logic sits on the mainboard and is not touched during the battery replacement. Our replacement cell matches the original charge curve, so you get the same charging times as with the factory battery.
Does 15W wireless charging stay intact on the Galaxy S23?
Yes. The wireless charging coil sits under the Armor Aluminum back cover on the Galaxy S23, not on the battery. During the replacement we open the device from the front via the display – the back with the Qi coil stays untouched. The 4.5W reverse wireless charging (charging other devices on the Galaxy S23 case) also stays functional.
Does the Galaxy S23 keep its IP68 water resistance after the battery replacement?
Yes. With every battery replacement we fully renew the IP68 Samsung seal around the display. After a proper fitting your Galaxy S23 reaches full protection again against splashes and brief submersion down to 1.5 m. We generally advise against active diving after any case intervention.
Does the display get damaged during the Galaxy S23 battery replacement?
No, not with us. Samsung bonds the display and case on the Galaxy S23 so that battery access only goes through the display. We warm the adhesive layer in a temperature-controlled way to 70 °C and release the panel with flat carbon spudgers – no bending, no pressure. On 2% of repairs the adhesive film still tears; in that case we replace the bonding free of charge and the IP68 seal comes new.
Can I drop my Galaxy S23 off directly at Reparo?
Reparo has no walk-in on site. You book an appointment online – our courier comes to your chosen address in all 23 Vienna districts (1010 to 1230). From the provinces you send the Galaxy S23 in insured, and the return shipping is included in the battery replacement price.
How does the pickup service in Vienna work for the Galaxy S23 battery replacement?
Book online, choose a time slot between 9 am and 6 pm, and our courier drives to your Vienna address (from the 1st district Innere Stadt to the 23rd, Liesing). The battery replacement takes 60–90 minutes in the studio, with a return often the same day. Pickup & delivery starts at EUR 7.90 by district.
Is shipping from the provinces safe for a Galaxy S23 battery?
Yes. Battery shipping falls under hazardous-goods class 9 – after booking we send you a special UN-approved shipping box. The Galaxy S23 comes to Vienna insured and compliant, and goes back the same way after the replacement. We regularly serve customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Is any data lost during the Galaxy S23 battery replacement?
No. The flash storage, Samsung account and SIM card are not disconnected during the battery replacement. Photos, WhatsApp chats, apps, Wi-Fi passwords – everything stays intact. We still recommend a Samsung Cloud backup before any repair (free, 5 minutes via the Samsung account settings).
How long is the warranty on the new Galaxy S23 battery?
Six months on the battery cell and the fitting. If the cell loses more than 10% capacity within that time, we replace it free of charge. Not covered are deep discharge from months of being left unused, or damage from third-party chargers without USB-PD certification.
Do I lose my Samsung warranty by replacing the Galaxy S23 battery?
The original Samsung warranty has already expired on most Galaxy S23 devices for 2+ years. Our Reparo warranty on the new battery cell runs for 6 months from fitting – on the cell and the labour.
Is the Galaxy S23 battery replacement still worth it in 2026?
Yes. The Galaxy S23 is supported by Samsung with security updates until 2030. A battery replacement at EUR 79 vs. a comparable used device with a fresh battery from around EUR 365 – plus data migration, fresh setup and lost 2FA tokens.
My Galaxy S23 was flat for months – can the battery still be replaced?
Yes, but diagnosis is mandatory. After deep discharge of more than 3 months the cell can be chemically damaged to the point that it no longer powers up when fitted. We check voltage and cell impedance in the diagnosis (EUR 25, waived on repair) – if only the cell is dead, the replacement is enough. With mainboard damage from deep discharge (rare) we discuss alternatives.
