Typical battery problems on the Galaxy S20 Ultra
- Your Galaxy S20 Ultra battery does not even last a working day – with the original battery you used to get 5–7 hours of screen time
- The device shuts down suddenly at 20–30 % charge left and only comes back on once plugged in
- The 5000 mAh battery gets noticeably hot while charging or during 45W fast charging – a sign of chemical ageing
- The dual-cell structure shows uneven discharge: the display jumps from 60 % to 20 %
- Wireless charging at 15W no longer works or charges very slowly
- The housing bulges in the battery area – visible battery swelling (consequence of deep discharge)
- The Galaxy S20 Ultra no longer starts at all after a full discharge – the battery is deeply discharged and will not take a charge
The Galaxy S20 Ultra was released in 2020 with a 5000 mAh dual-cell – this exact specification ages audibly after 2–3 years. Anyone who ignores battery shutdowns risks deep discharge and permanent cell damage that makes a simple battery swap impossible. See our Galaxy S20 Ultra repair overview for all options.
How does the Galaxy S20 Ultra 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 S20 Ultra. Capacity below 80 % or a cycle count above 500 justifies the replacement.
- Detach the display unit under temperature control
On Samsung S/A devices the battery sits beneath the display – the OLED panel is warmed evenly with heat to around 70 °C and loosened with flat carbon spudgers, without warping the aluminium frame.
- Remove the old battery in a controlled way
Both battery cells (dual-cell layout) are fixed to the housing 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.
- Fit the certified battery cell
The dual-cell pack with 5000 mAh total capacity is connected to the original connector on the mainboard and fixed to the aluminium frame with Samsung adhesive. Polarity and contact pressure are checked – incorrect positioning costs 3 % capacity.
- Display assembly + 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 seal values are restored.
- Full charge + calibration
First charge to 100 % at 25 °C room temperature – then a full discharge and recharge. This calibrates the battery gauge to the new cell characteristics. You get your Galaxy S20 Ultra back with a precisely calibrated battery.
Reparo works without customer access – your Galaxy S20 Ultra is collected by courier in Vienna or sent in from the federal states in a hazardous-goods-compliant shipping box.
Replacing the Galaxy S20 Ultra battery – process, price, battery life in Vienna
The Samsung Li-Po battery in the Galaxy S20 Ultra has 5000 mAh capacity, built as a dual-cell pack split across two cells connected in parallel. After 500 to 700 full cycles (usually 2–3 years of everyday use) the usable capacity drops below 80 % – you notice this through spontaneous shutdowns between 20 and 30 %, a hot housing during 45W charging or a visible bulging of the back. Our Galaxy S20 Plus shows similar symptoms, but the repair effort and price differ.
Reparo replaces the Galaxy S20 Ultra battery in Vienna for a 99 € fixed price – that is about 7 % of the original launch price (1349 €). Included are certified 5000 mAh cells, a new IP68 seal, calibration and 6 months warranty. Anyone who also has display cracks or touch problems saves with the combined repair – see our separate S20 Ultra screen replacement for details.
Certified cell vs. original Samsung – what goes into the Galaxy S20 Ultra?
For the Galaxy S20 Ultra we fit certified battery cells that meet the original Samsung specifications: same nominal voltage (3.85 V), same 5000 mAh capacity, same charge curve. Original Samsung replacement cells have only been available as remaining stock for older models like the Galaxy S20 Ultra for some time. Our cells last measurably as long as the originals – 500 to 700 cycles without significant capacity loss. You can see all options in the price comparison on the Samsung repair overview.
Frequently asked questions about the Galaxy S20 Ultra battery replacement
What does the battery replacement cost for the Galaxy S20 Ultra?
The Galaxy S20 Ultra battery replacement costs 99 € fixed price at Reparo in Vienna. Included in the price: a certified Samsung-compatible battery cell with 5000 mAh, a new IP68 seal, calibration and 6 months warranty. The diagnostic (25 EUR) is waived on repair.
How long does the new Galaxy S20 Ultra battery last?
The replacement battery lasts 500 full cycles with at least 80 % capacity under normal use – that corresponds to about 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 is 6 months on the cell and fitting.
Why does the Galaxy S20 Ultra have two battery cells instead of one?
Samsung uses a dual-cell design on the Galaxy S20 Ultra: the 5000 mAh are split across two smaller cells that charge in parallel. This enables 45W fast charging with less heat per cell. During the swap we fit both cells as a certified pack – replacing a single cell makes no technical sense.
Does 45W Super Fast Charging work on the Galaxy S20 Ultra after the swap?
Yes. The 45W fast-charging electronics sit on the mainboard of the Galaxy S20 Ultra, not in the battery. Our replacement cell supports the full 45W Power Delivery protocol and charges with original Samsung 25W/45W chargers in the same time as before. The cell chemistry is designed for high-current charging.
Does wireless charging at 15W stay intact on the Galaxy S20 Ultra?
Yes. The wireless charging coil sits beneath the aluminium back cover on the Galaxy S20 Ultra, not on the battery. During the battery replacement we open the device from the front via the display – the back with the Qi coil stays untouched. The 9W reverse wireless charging (charging other devices on the Galaxy S20 Ultra housing) also stays functional.
Does the IP68 water protection stay intact on the Galaxy S20 Ultra after the battery replacement?
Yes. With every battery replacement we completely renew the IP68 Samsung seal around the display. After professional fitting your Galaxy S20 Ultra regains full protection against splash water and brief immersion up to 1.5 m. We generally do not recommend active diving after any housing intervention.
Does the display get damaged during the Galaxy S20 Ultra battery replacement?
No, not with us. Samsung bonds the display and housing on the Galaxy S20 Ultra so that battery access is only possible via the display. We warm the adhesive layer under temperature control to 70 °C and loosen 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 at no charge and the IP68 seal comes new.
Can I bring my Galaxy S20 Ultra directly to Reparo?
Reparo has no on-site customer access. You book an appointment online – our courier comes to your chosen address across all 23 Vienna districts (1010 to 1230). From the federal states you send the Galaxy S20 Ultra in insured, and the return shipping is included in the battery replacement price.
How does the pickup service in Vienna work for the Galaxy S20 Ultra battery replacement?
Book online, choose a time slot between 9 and 18:00, and our courier drives to your Vienna address (1st district Innere Stadt to 23rd Liesing). Battery replacement in the studio takes 60–90 minutes, return often the same day. Courier costs are included in the 99 € fixed price.
Is shipping from the federal states safe for a Galaxy S20 Ultra battery?
Yes. Battery shipping falls under hazardous-goods class 9 – after booking we send you a special UN-approved shipping box. The Galaxy S20 Ultra comes to Vienna insured and compliant and goes back the same way after the swap. Regular customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Is any data lost during the Galaxy S20 Ultra battery replacement?
No. 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 every repair (included, 5 minutes via the Samsung account settings).
How long is the warranty on the new Galaxy S20 Ultra battery?
Six months on the battery cell and the fitting. If the cell loses more than 10 % capacity within that time, we replace it at no charge. Not covered are deep discharge from months of being left lying around or damage from third-party chargers without USB-PD certification.
Do I lose the Samsung warranty through the Galaxy S20 Ultra battery replacement?
The original Samsung warranty has expired on most Galaxy S20 Ultra devices for 2+ years. Our Reparo warranty on the new battery cell is valid for 6 months from fitting – on the cell and the work.
Is the Galaxy S20 Ultra battery replacement still worth it in 2026?
Yes. The Galaxy S20 Ultra is still supplied by Samsung with security updates until 2024. Battery replacement 99 € vs. a comparable used device with a fresh battery from about 337 € – plus data migration, new setup, lost 2FA tokens.
My Galaxy S20 Ultra was empty for months – can the battery still be replaced?
Yes, but a diagnosis is mandatory. With a deep discharge over more than 3 months the cell can be so chemically damaged that it no longer wakes up on fitting. We check voltage and cell impedance in the diagnostic (25 EUR, waived on repair) – if only the cell is dead, the swap is enough. With mainboard damage from deep discharge (rare) we discuss alternatives.
