Typical battery problems on the Galaxy A20s
- The Galaxy A20s no longer lasts a working day - you used to easily reach 5-7 hours of screen time
- The device suddenly shuts down at 20-30 % remaining charge and only turns on again once plugged in
- The 4000-mAh battery gets noticeably hot while charging or during 15W fast charging
- The battery percentage jumps in large steps (60 % to 20 %) - the calibration is lost
- The back cover bulges around the battery area - visible swelling (a deep-discharge consequence)
- The device no longer starts after a full discharge - the battery is deeply discharged
The Galaxy A20s launched in 2019. An ignored fault quickly leads to follow-up damage - see the Galaxy A20s repair overview for all options.
How does the Galaxy A20s battery replacement work?
- Battery diagnosis
The Samsung service code *#0228# shows voltage, temperature and cycle count. Capacity below 80 % or more than 500 cycles justifies a replacement.
- Open the back cover or display
On the Galaxy A20s the battery sits behind the back cover on models from 2021 on. We warm the adhesive layer to 70 C and release it carefully.
- Remove the old battery
The 4000-mAh cell is fixed to the plastic frame with pull tabs. We loosen the adhesive with isopropanol-99, never with a screwdriver as a lever.
- Fit the certified 4000-mAh cell
Same nominal voltage (3.85 V), same capacity, same form factor. Connector to the mainboard, adhesive on the frame, contact pressure controlled.
- Resealing
The frame is closed with fresh adhesive. The Galaxy A20s has no factory IP protection - but dust and splash-water resistance is restored.
- Full charge + calibration
First charge at 25 C to 100 %, then a full discharge and another charge. The battery gauge is calibrated to the new cell.
Reparo works without customer access on site - your Galaxy A20s is collected by courier in Vienna or sent in insured (hazardous-goods-compliant shipping box).
Replace the Galaxy A20s battery - price, process and battery life in Vienna
The 4000-mAh battery in the Galaxy A20s lasts 500 to 700 full cycles with normal use - that usually means 2 to 3 years of everyday use. After that the usable capacity drops below 80 %, which you notice through battery shutdowns at 20-30 %, a hot housing while charging or a bulging part of the case. Our Galaxy A52 shows similar ageing patterns, but the battery cells and prices differ.
Reparo replaces the Galaxy A20s battery in Vienna for a 55 EUR fixed price - that is about 18 % of the original launch price (300 EUR). Included are certified 4000-mAh cells, calibration and 6 months warranty. If you also have display issues: see the A20s screen replacement.
Certified cell vs. Samsung original - what goes into the Galaxy A20s?
We fit certified 4000-mAh battery cells into the Galaxy A20s that match the original Samsung specifications: 3.85 V, same charging curve. Original Samsung service packs are only available through Samsung service centres - our aftermarket cells last measurably the same. Price comparison of all battery repairs: Samsung overview.
Frequently asked questions about the Galaxy A20s battery replacement
What does a battery replacement cost on the Galaxy A20s?
The Galaxy A20s battery replacement costs 55 EUR fixed price at Reparo in Vienna. Included: a certified 4000-mAh battery cell, calibration, 6 months warranty. The 25 EUR diagnostic check is waived on a repair order.
How long does the new Galaxy A20s battery last?
The replacement battery lasts 500 full cycles with at least 80 % capacity - around 2.5 to 3.5 years of everyday use. One full cycle = a complete discharge from 100 % to 0 %.
Is the 4000-mAh battery on the Galaxy A20s a standard replacement or original?
We fit certified 4000-mAh battery cells with original Samsung specifications: the same 3.85 V, the same capacity, the same charging curve. Original Samsung service packs are only available through Samsung service centres and are not obtainable for independent workshops.
Does the Galaxy A20s charge just as fast at 15W after the battery replacement?
Yes. The Galaxy A20s supports 15W charging via USB-PD - the logic sits on the mainboard and is not touched. The same charging times as from the factory.
Does the Galaxy A20s have wireless charging?
No, the Galaxy A20s has no wireless charging by design - Samsung leaves out the Qi coil on the A series to optimise price and weight. Charging is exclusively via USB-C at up to 15W.
Does the Galaxy A20s have water protection?
No, the Galaxy A20s has no factory IP rating. During the battery replacement we seal the housing with fresh adhesive against dust and splash water - avoid active submersion.
Will the display be damaged during the Galaxy A20s battery replacement?
No, not with us. On Galaxy A20s models with the battery under the display we warm the adhesive layer under temperature control and release it without bending or pressure. If the adhesive strip tears, we renew it free of charge.
Can I bring my Galaxy A20s directly to Reparo?
Reparo has no customer access on site. You book online and our courier comes to all 23 districts of Vienna. From the federal provinces, send it in insured.
How does the pickup service in Vienna work for the Galaxy A20s battery replacement?
Book online, choose a time slot (9am-6pm), the courier drives to your Vienna address. The battery replacement takes 60-90 min in the studio, return often on the same day. The courier is included in the 55EUR fixed price.
Is shipping from the provinces safe for a Galaxy A20s battery?
Yes. Battery shipping falls under hazardous-goods class 9 - we send a special UN-approved shipping box. The Galaxy A20s comes to Vienna insured and goes back the same way.
Is any data lost during the Galaxy A20s battery replacement?
No. Flash storage, Samsung account and SIM stay untouched. Photos, WhatsApp chats, apps - everything stays. A Samsung Cloud backup is still recommended (5 min, included).
How long is the warranty on the new Galaxy A20s battery?
Six months on the cell and the fitting. If the cell loses more than 10 % capacity within that time: a free re-replacement. Not covered: deep discharge from leaving it lying around for months.
Do I lose the Samsung warranty through the Galaxy A20s battery replacement?
The Samsung original warranty has expired on most Galaxy A20s devices for 2+ years. The Reparo warranty is 6 months on the cell and the work.
Is the Galaxy A20s battery replacement still worth it in 2026?
Yes. A battery replacement at 55 EUR vs. a used device from around 120 EUR - plus data migration and setting up new 2FA cost time. The Galaxy A20s still partly gets security updates from Samsung.
My Galaxy A20s was empty for months - can the battery still be replaced?
Yes, but a diagnosis is mandatory. After a deep discharge of more than 3 months the cell can be irreversibly damaged. We check the voltage in the diagnosis (25 EUR, waived on repair).
