Typical battery problems on the Galaxy S20
- Your Galaxy S20 battery does not even last through a workday – with the original cell, 5–7 hours of screen time used to be possible
- The device suddenly shuts down at 20–30 % remaining charge and only comes back on once plugged in
- The 4000 mAh battery gets noticeably hot while charging or during 25W fast charging – a sign of chemical ageing
- The battery percentage jumps in steps of 10 instead of continuously – the calibration is lost
- Wireless charging at 15W no longer works or charges only very slowly
- The housing bulges in the battery area – visible battery swelling (consequence of deep discharge)
- The Galaxy S20 no longer starts at all after a full discharge – the battery is deeply discharged and takes no charge
The Galaxy S20 launched in 2020 with a 4000 mAh single cell – it is exactly this specification that ages audibly after 2–3 years. Anyone who ignores battery shutdowns risks deep discharge and permanent cell damage that makes a simple battery replacement impossible. See our Galaxy S20 repair overview for all options.
How does the Galaxy S20 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. Capacity below 80 % or a cycle count above 500 justifies the replacement.
- Detach the display unit under controlled temperature
Samsung S/A devices have the battery underneath the display – the OLED panel is heated evenly with heat to about 70 °C and loosened with flat carbon spudgers, without warping the aluminium frame.
- Remove the old battery in a controlled way
The single battery cell is fixed to the housing with adhesive. We loosen the glue with 99 % isopropanol and fine pull tabs – never using screwdrivers as a lever. For swollen batteries: hazardous-goods disposal directly by Reparo.
- Install the certified battery cell
The single cell with 4000 mAh 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 re-bonded under defined pressure. After 30 minutes of curing time the sealing values are restored.
- Full charge + calibration
First charge to 100 % at 25 °C room temperature – then full discharge and recharge. This calibrates the battery gauge to the new cell characteristic. You get your Galaxy S20 back with a precisely calibrated battery.
Reparo works without customer access on site – your Galaxy S20 is picked up by courier in Vienna or sent in from the provinces in a hazardous-goods-compliant shipping box.
Replacing the Galaxy S20 battery – process, price, battery life in Vienna
The Samsung Li-Po battery in the Galaxy S20 has a capacity of 4000 mAh, designed as a single cell. After 500 to 700 full cycles (usually equivalent to 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 25W charging or visible bulging of the back. Our Galaxy S20 Plus shows similar symptoms, but the repair effort and price differ.
Reparo replaces the Galaxy S20 battery in Vienna for a fixed price of €79 – that is about 9 % of the former retail price (€849). Included are certified 4000 mAh cells, a new IP68 seal, calibration and 6 months warranty. Anyone who also has cracked display or touch problems saves with the combined repair – see our separate S20 screen replacement for details.
Certified cell vs. original Samsung – what goes into the Galaxy S20?
For the Galaxy S20 we fit certified battery cells that match the original Samsung specifications: same nominal voltage (3.85 V), same 4000 mAh capacity, same charge curve. Original Samsung replacement cells for older models like the Galaxy S20 have been available only as remaining stock for some time now. Our cells last measurably as long as originals – 500 to 700 cycles without significant capacity loss. You can see all options in the price comparison on the Samsung repair overview.

What does the battery replacement for the Galaxy S20 cost?

How long does the new Galaxy S20 battery last?
With normal use the replacement battery lasts 500 full cycles with at least 80 % capacity – that corresponds to about 2.5 to 3.5 years of everyday use. One full cycle = one complete discharge from 100 % to 0 %. Partial charges count proportionally. The warranty applies for 6 months on cell and installation.
Is the 4000 mAh battery in the Galaxy S20 a standard replacement or original?
We fit certified 4000 mAh battery cells that match the original Samsung specifications – same voltage (3.85 V), same capacity, same form factor. Original Samsung service packs are only available through Samsung service centres and are not available to independent workshops. Our replacement cells last measurably as long.
Does the Galaxy S20 charge as fast at 25W as before after the battery replacement?
Yes. The Galaxy S20 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 wireless charging at 15W stay intact on the Galaxy S20?
Yes. The wireless charging coil sits under the aluminium back cover on the Galaxy S20, 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 housing) also stays functional.
Does the IP68 water protection stay intact on the Galaxy S20 after the battery replacement?
Yes. With every battery replacement we completely renew the IP68 Samsung seal around the display. After professional installation your Galaxy S20 again reaches full protection against splash water and brief immersion up to 1.5 m. We generally do not recommend active diving after housing interventions.
Is the display damaged during the Galaxy S20 battery replacement?
No, not with us. Samsung bonds the display and housing on the Galaxy S20 so that battery access is only possible via the display. We heat the adhesive layer in a temperature-controlled way 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 included and the IP68 seal is renewed.

Is data lost during the Galaxy S20 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 every repair (included, 5 minutes via the Samsung account settings).
How long is the warranty on the new Galaxy S20 battery?
Six months on the battery cell and the installation. If the cell loses more than 10 % capacity in this time, we replace it included. Not covered are deep discharge from being left unused for months or damage from third-party chargers without USB-PD certification.
Do I lose the Samsung warranty through the Galaxy S20 battery replacement?
The original Samsung warranty has expired on most Galaxy S20 devices for 2+ years. Our Reparo warranty on the new battery cell applies for 6 months from installation – on cell and labour.
Is the Galaxy S20 battery replacement still worth it in 2026?
Yes. The Galaxy S20 was supplied by Samsung with security updates until 2024. Battery replacement €79 vs. a comparable used device with a fresh battery from about €212 – plus data migration, new setup, lost 2FA tokens.
