What is an S20 ULTRA 5G battery replacement?
A battery replacement for the Galaxy S20 ULTRA 5G means removing the old Li-ion battery pack and fitting a new compatible battery (typically the full replacement battery designed for the S20 ULTRA 5G model). The battery assembly supplies the phone’s power and is connected to the mainboard via flex cables; replacing it restores capacity, fixes swelling, and resolves many charge/boot issues. The Galaxy S20 ULTRA 5G ships with an mAh cell (typical).
When do you need one?
Common signs you need a replacement: fast battery drain, sudden shutdowns, slow/failed charging, battery swelling, and large drops in battery health reported in Settings. Visible swelling or overheating means stop using the phone and get it serviced immediately.
OEM vs aftermarket batteries
- OEM (genuine Samsung) batteries match factory specs, charge profile, safety circuitry and give the best long-term reliability — but they cost more and may only be available through official channels or authorized parts distributors. (Samsung Parts)
- Aftermarket / third-party batteries vary widely: good-quality replacements can be reliable and much cheaper, while very cheap units risk poor capacity, faster degradation, or safety problems (overheating/swell). Always choose a reputable supplier and a shop that offers parts warranty.

Notes on pricing: labour, battery authenticity (OEM vs aftermarket), warranty length, and additional repairs (e.g., swollen battery causing panel/frame damage) affect the final bill. Always ask for a written parts & labour warranty.
Samsung Care+, warranties and why it matters
Battery failures due to manufacturing defects may be covered under the device warranty for a limited time; accidental damage and normal battery wear usually are not. Samsung Care+ or local device insurance may give lower-cost battery replacements or discounted service options — coverage varies by plan and region. If your S20 ULTRA 5G is under a manufacturer warranty or Care+ plan, check terms before paying for a private replacement.
How the replacement is done (step-by-step)
- Initial inspection & quote — tech checks battery health, swelling, and any additional damage; gives cost and ETA.
- Backup advice & power down — recommend user backup data; technician powers down device before work.
- Disassembly — remove back cover (heat + pry), disconnect battery connector, detach adhesive strips, and carefully remove the old battery. Safety protocols for swollen cells are followed.
- Install new battery — fit the replacement battery, connect flex cable, test charging and boot. Reapply seals/adhesive; replace back cover.
- Calibration & testing — charge to ~100% and run tests (charging behavior, temperature, battery reporting, and a short stress test).
- Final QA & handover — provide written parts & labour warranty and aftercare tips (avoid full-time fast charging, avoid extreme temperatures).
Typical turnaround: many shops complete standard battery swaps same-day (30 minutes to a few hours) if the part is in stock. If parts need ordering, allow 1–3 days.
Risks, pros & cons (safety, longevity, warranty)
Risks / cons
- Safety risks with poor parts: cheap batteries can swell, overheat, or fail — choose reputable parts.
- Loss of water resistance: opening the device may reduce factory seals — ask the shop about re-sealing.
Pros
- Restores capacity and performance at a fraction of the cost of replacing the phone.
- OEM battery keeps charging profile and longevity closest to stock performance.
Where to get it repaired (official Samsung, authorized centers, reputable local shops)
- Official Samsung / authorized service centers — best for guaranteed genuine parts and warranty alignment; check Samsung support for local centers and official part pricing.
- Reputable local shops in Nairobi — many offer quick, affordable battery swaps with a short warranty; verify reviews and request to see the replacement battery before fitting. Example listings show KSh ~1,999–2,500 for S20 ULTRA 5G battery swaps in Nairobi.
How to choose: OEM vs third-party (cost vs safety)
- Choose OEM if: you want original safety circuitry, full charge compatibility, and maximum longevity — and you can accept higher cost or official service timelines.
- Choose high-quality third-party if: you need a lower cost swap and the supplier is reputable with a parts warranty. Avoid very cheap no-name batteries.
