Typical battery problems on the Galaxy S23 Plus
- Your Galaxy S23 Plus battery won't even get you through a working day – fresh from the box it used to manage 5–7 hours of screen time
- The phone shuts down suddenly at 20–30% remaining and only comes back on once you plug it in
- The 4700 mAh battery gets noticeably hot while charging or during 45W fast charging – a sign of chemical ageing
- The battery percentage jumps in steps of 10 rather than counting down smoothly – the calibration is lost
- 15W wireless charging no longer works or charges only very slowly
- The housing bulges around the battery area – visible battery swelling (a consequence of deep discharge)
- The Galaxy S23 Plus won't start at all after a full discharge – the battery is deeply discharged and refuses to take any charge
The Galaxy S23 Plus launched in 2023 with 4700 mAh (200 mAh more than the S22 Plus) – and it is exactly this specification that ages noticeably after 2–3 years. Ignore battery shutdowns and you risk deep discharge and permanent cell damage that makes a simple battery swap impossible. See our Galaxy S23 Plus repair overview for all your options.
How does the Galaxy S23 Plus 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 Plus. A capacity below 80% or a cycle count over 500 justifies the replacement.
- Lift off the display unit under temperature control
On Samsung S/A devices the battery sits beneath the display – the OLED panel is warmed evenly to roughly 70 °C and released with flat carbon spudgers, without distorting the Armor Aluminum frame.
- Remove the old battery carefully
The single battery cell is glued to the housing. We loosen the adhesive with 99% isopropanol and fine pull tabs – never using a screwdriver as a lever. For swollen batteries: hazardous-goods disposal handled directly by Reparo.
- Fit the certified battery cell
A single cell with 4700 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 – wrong positioning costs 3% capacity.
- Reassemble the display + renew the IP68 seal
The old adhesive film is fully removed, a new IP68 Samsung seal is applied and the display is bonded back 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 a fresh charge. This calibrates the battery gauge to the new cell's characteristics. You get your Galaxy S23 Plus back with a precisely calibrated battery.
Reparo works without a walk-in counter – your Galaxy S23 Plus is collected by courier in Vienna or sent in from the provinces in a hazardous-goods-compliant shipping box.
Replacing the Galaxy S23 Plus battery – process, price and battery life in Vienna
The Samsung Li-Po battery in the Galaxy S23 Plus has a 4700 mAh capacity, 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 in spontaneous shutdowns between 20 and 30%, a hot housing during 45W charging or a visible bulge in the back. Our Galaxy S23 shows similar symptoms, but the repair effort and the price differ.
Reparo replaces the Galaxy S23 Plus battery in Vienna for a fixed EUR 89 – roughly 8% of the original launch price (EUR 1099). That includes a certified 4700 mAh cell, a new IP68 seal, calibration and a 6-month warranty. If you also have a cracked display or touch problems, a combined repair saves money – see our separate S23 Plus screen replacement for details.
Certified cell vs. original Samsung – what goes into the Galaxy S23 Plus?
For the Galaxy S23 Plus we fit certified battery cells that match the original Samsung specifications: the same nominal voltage (3.85 V), the same 4700 mAh capacity, the same charge curve. Samsung service-pack cells are only available through authorised Samsung service centres. Our cells measurably last as long as the originals – 500 to 700 cycles without 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 Plus battery replacement
What does a battery replacement for the Galaxy S23 Plus cost?
The Galaxy S23 Plus battery replacement costs a fixed EUR 89 at Reparo in Vienna. The price includes a certified Samsung-compatible battery cell with 4700 mAh, a new IP68 seal, calibration and a 6-month warranty. The diagnostic check (EUR 25) is waived on repair.
How long does the new Galaxy S23 Plus 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 6 months on the cell and the fitting.
Is the 4700 mAh battery in the Galaxy S23 Plus a standard replacement or original?
We fit certified 4700 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 are not available to independent workshops. Our replacement cells measurably last just as long.
Does 45W Super Fast Charging still work on the Galaxy S23 Plus after the swap?
Yes. The 45W fast-charging electronics sit on the Galaxy S23 Plus mainboard, not in the battery. Our replacement cell supports the full 45W power-delivery protocol and charges in the same time as before with original Samsung 25W/45W chargers. The cell chemistry is built for high-current charging.
Does 15W wireless charging on the Galaxy S23 Plus stay intact?
Yes. The wireless-charging coil sits under the Armor Aluminum back cover of the Galaxy S23 Plus, not on the battery. During the battery swap 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 Plus housing) also stays functional.
Does the IP68 water resistance of the Galaxy S23 Plus stay intact after the battery swap?
Yes. With every battery swap we completely renew the IP68 Samsung seal around the display. After a professional fitting your Galaxy S23 Plus once again reaches full protection against splash water and brief immersion up to 1.5 m. We generally do not recommend active diving after any housing intervention.
Is the display damaged during the Galaxy S23 Plus battery swap?
Not with us. Samsung bonds the display and housing on the Galaxy S23 Plus so that the battery can only be reached through the display. We warm the adhesive layer under temperature control to 70 °C and release the panel with flat carbon spudgers – no bending, no pressure. In 2% of repairs the adhesive film tears anyway; in that case we replace the bonding free of charge and the IP68 seal goes in fresh.
Can I just drop my Galaxy S23 Plus off at Reparo?
Reparo has no walk-in counter on site. You book an appointment online – our courier comes to your chosen address across all 23 Vienna districts (1010 to 1230). From the provinces you send the Galaxy S23 Plus 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 Plus battery swap?
Book online, choose a time window 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 swap takes 60–90 minutes in the studio, with return often the same day. Pickup costs start from EUR 7.90 by district.
Is shipping from the provinces safe for a Galaxy S23 Plus battery?
Yes. Battery shipping falls under hazardous-goods class 9 – after booking we send you a special UN-approved shipping box. The Galaxy S23 Plus reaches Vienna insured and compliant, and goes back the same way after the swap. We regularly get customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Is any data lost during the Galaxy S23 Plus battery swap?
No. The flash storage, Samsung account and SIM card are not disconnected during the battery swap. Photos, WhatsApp chats, apps, Wi-Fi passwords – everything stays in place. 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 Plus battery?
Six months on the battery cell and the fitting. If the cell loses more than 10% capacity in that time, we replace it free of charge. Not covered are deep discharge from leaving the phone lying unused for months, or damage from third-party chargers without USB-PD certification.
Do I lose the Samsung warranty by replacing the Galaxy S23 Plus battery?
The original Samsung warranty has expired on most Galaxy S23 Plus devices, as they are 2+ years old. Our Reparo warranty on the new battery cell runs 6 months from fitting – on the cell and the labour.
Is a Galaxy S23 Plus battery replacement still worth it in 2026?
Yes. The Galaxy S23 Plus is supported by Samsung with security updates until 2030. A battery swap at EUR 89 vs. a comparable second-hand device with a fresh battery from around EUR 472 – plus the data migration, the new setup and lost 2FA tokens.
My Galaxy S23 Plus was flat for months – can the battery still be swapped?
Yes, but a diagnosis is mandatory. With deep discharge over more than 3 months the cell can be so chemically damaged that it no longer wakes up on fitting. We check the voltage and cell impedance in the diagnosis (EUR 25, waived on repair) – if only the cell is dead, the swap is enough. With mainboard damage from deep discharge (rare) we discuss alternatives.
