Samsung Galaxy Note20 Ultra Battery Replacement | Original Grade | 4500mAh Capacity | Fitting Labour Included
Restore all-day stamina to your S Pen workhorse through a professional swap at our downtown service bench.
Condition: New
Note: price and availability are subject to change without prior notice
Samsung Galaxy Note20 Ultra owners can get a brand new original-grade 4500mAh battery fitted at Mascom International for KSh 3,000, labour included. The service runs from our store at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, where our technicians lift the back glass, take out the worn cell and install the replacement. The Samsung Galaxy Note20 Ultra reached shops in August 2020 with a 4500mAh battery and 25W wired charging. After years of daily top-ups, most of these phones hold far less charge than they did out of the box. This is the fix that brings that stamina back.
Designed for accountants, doctors, logistics coordinators and NGO field staff who still write notes and sign documents with the S Pen, the Samsung Galaxy Note20 Ultra remains a working tool for many Kenyans. The trouble is usually the cell, not the phone. Buyers throughout Kenya report the charge falling sharply by midday, the phone getting warm during light use, or shutting down while the screen still shows charge left. A replacement battery solves that without forcing you to move apps, contacts and years of photos to another device. Your 6.9-inch screen and stylus workflow stay exactly as they are.
Unlike other electronics retailers in Kenya that hand over loose batteries with no fitting support, Mascom International installs the part, tests the phone with you and backs the work with a 6-month warranty. The Samsung Galaxy Note20 Ultra has a slim 8.1mm body, so careful fitting matters, because a misaligned cell can press on the display or strain the internal ribbon cables. Message us on WhatsApp with your model number before you come, back up your data, and bring the phone in during business hours. A Samsung Galaxy Note20 Ultra battery replacement at KSh 3,000 is a small cost next to buying another phone.
Common Questions About the Samsung Galaxy Note20 Ultra Battery Replacement
What is the Samsung Galaxy Note20 Ultra battery replacement price in Kenya?
The Samsung Galaxy Note20 Ultra battery replacement price at Mascom International in Nairobi is KSh 3,000, with fitting labour included. You pay once for the original-grade 4500mAh cell and the technician's time to open, fit, reseal and test the phone. No separate part-only charge applies. The Samsung Galaxy S22 Ultra battery service costs the same KSh 3,000, while the Samsung Galaxy S20 version is KSh 2,800. A 6-month warranty on the fitted battery is included at no extra cost.
Why does my Samsung Galaxy Note20 Ultra lose charge so quickly now?
A Samsung Galaxy Note20 Ultra that loses charge quickly almost always has a worn lithium-ion cell that can no longer hold its rated 4500mAh. Every cell loses capacity with age and heat, and phones from 2020 have been through years of daily charging. Other warning signs include the phone turning off before it reaches empty, warmth during simple tasks, and the back glass bulging away from the stainless steel frame. A bulging back means the cell is swelling, so stop charging and bring the phone to Mascom International soon.
How does the Samsung Galaxy Note20 Ultra battery swap compare with the Samsung Galaxy S22 Ultra one?
Both services cost KSh 3,000 at Mascom International, but the Samsung Galaxy Note20 Ultra takes a 4500mAh cell while the Samsung Galaxy S22 Ultra takes a 5000mAh cell. The Samsung Galaxy Note20 Ultra also charges at up to 25W wired, against 45W on the Samsung Galaxy S22 Ultra. Neither battery fits the other phone, so the choice simply follows the handset you own. If you are deciding which older Samsung to keep running, the Samsung Galaxy S22 Ultra gives you the larger cell and faster charging.
Is a Samsung Galaxy Note20 Ultra battery swap worth it for heat, power cuts and all-day M-Pesa use?
A Samsung Galaxy Note20 Ultra battery swap is worth it for Kenyans who depend on the phone through long days away from a socket. A healthy 4500mAh cell carries M-Pesa payments, Safaricom calls and WhatsApp through evening KPLC outages far better than a worn one. Heat is the main enemy of lithium cells, so owners in Mombasa, Malindi and other warm, humid towns see batteries age faster. Keep the phone out of direct sun on boda boda rides and avoid charging it under a pillow at night.
Will the S Pen on my Samsung Galaxy Note20 Ultra still work after the replacement?
Yes, the S Pen on your Samsung Galaxy Note20 Ultra keeps working after the battery replacement, because the stylus silo and the digitiser are separate from the main cell. The digitiser is the layer under the screen that reads the pen tip. Our technicians test writing, Air Actions and stylus detection at the counter before handing the phone back. If the S Pen had a fault before your visit, mention it on WhatsApp so we can check it separately.
Who should book a Samsung Galaxy Note20 Ultra battery replacement, and who should skip it?
A Samsung Galaxy Note20 Ultra battery replacement is right for owners whose phone works well apart from short battery life. Professionals in Upper Hill who sign forms with the S Pen, and University of Nairobi students who take handwritten notes, often fall in this group. Skip it if the curved screen is cracked or has dead patches, since the display needs attention first and Mascom International offers screen repairs as well. Skip it too if the phone keeps restarting even on a charger, as that points to a board fault.
Does opening the Samsung Galaxy Note20 Ultra for a battery change affect its IP68 rating?
Yes, opening the Samsung Galaxy Note20 Ultra disturbs the factory seal behind its IP68 water-resistance rating, so treat the phone as no longer water-resistant afterwards. Any battery change requires lifting the Gorilla Glass Victus back, which breaks the original adhesive. We reseal the panel with fresh adhesive, but a repair shop cannot repeat the factory water test. Keep the phone dry during the long rains, avoid using it near pools, and carry it in a zipped pocket on wet days.
Is it still worth fixing a Samsung Galaxy Note20 Ultra from 2020?
Fixing a Samsung Galaxy Note20 Ultra from 2020 is worth it when the screen, camera and S Pen still meet your needs. The phone still offers a 6.9-inch 120Hz display, a stainless steel frame and a built-in stylus that most budget phones lack. A KSh 3,000 battery restores daily stamina without the cost of another handset. It is less worth it if the banking or work apps you rely on stop supporting the phone's software, so check those apps before booking the service.
Technical Specifications
Cell Rating and Chemistry
- 4500mAh rated capacity — the figure Samsung lists for this phone, bringing back a full working day of mixed use.
- Lithium-ion cell — the same chemistry as the factory battery, so the phone's power management handles it normally.
- Original-grade construction — sized and wired to match the factory part, so it sits flush inside the slim frame.
- Unused part straight from stock — no previous owner and no hidden wear from another handset's charging habits.
- Fits the 8.1mm chassis — slim enough to leave room for the S Pen silo and the wireless charging coil beside it.
Matching Your Exact Model
- Fits SM-N985F and SM-N985F/DS — the global single-SIM and dual-SIM versions listed for this phone on its spec sheet.
- Exynos 990 and Snapdragon 865+ versions — both chip versions carry the same 4500mAh battery rating on the spec sheet.
- 5G versions confirmed first — send the model number from Settings on WhatsApp so we match the correct part.
- Not for the Samsung Galaxy Note20 — the smaller non-Ultra model uses a different cell and a different body shape.
- Screenshot of the About phone page — the quickest way to confirm your exact version before travelling to the CBD.
Charging Speeds and Standards
- 25W wired charging over USB Power Delivery 3.0 — a shared standard letting charger and phone settle on a safe speed.
- USB Type-C 3.2 port — untouched during fitting, so your current USB-C cable and wall charger keep working.
- 15W Qi wireless charging — the coil is reconnected before the back closes, so your charging pad still works.
- 4.5W reverse wireless charging — the phone can still share power with earbuds or a watch placed on its back.
- Branded chargers recommended — unbranded chargers can deliver unstable power that wears a fresh cell faster.
Workshop Fitting on Kimathi Street
- KSh 3,000 covers part and labour — opening, fitting, resealing and testing are all included in the single price.
- Hands-on service at First Floor Room 4 — you meet the technician and collect the phone at the same counter.
- Worn cell removed and isolated — old batteries are never reused inside another customer's phone.
- Fresh adhesive on the back glass — holds the panel firmly and keeps dust and pocket lint out of the frame.
- Handover test with you — charging, calls, the S Pen and wireless charging are checked before you leave.
Inspection and Handling Standards
- Visual check for swelling first — a bulging cell is removed with care to protect the 6.9-inch display above it.
- Charging confirmed on the bench — the phone must accept power from a charger before it is handed back.
- IP68 rating no longer applies after opening — any battery work disturbs the original factory seal on the back.
- 6-month warranty on the fitted battery — covers manufacturing defects in the part under normal daily use.
- Safe storage of removed cells — damaged lithium batteries are kept away from heat and general waste bins.
Handset Reference Details
- 6.9-inch Dynamic AMOLED 2X display — a large, bright screen that is the biggest draw on the battery each day.
- 120Hz refresh rate — the screen redraws up to 120 times a second for smooth scrolling, at a cost in charge.
- 1440 x 3088 resolution — sharp detail for reading documents, though running at full resolution uses more power.
- Stainless steel frame and Gorilla Glass Victus — a sturdy body that can stay in service once the cell is renewed.
- 164.8 x 77.2 x 8.1mm body at 208g — the battery swap leaves the phone's size and feel in the hand as before.
