Signs of a worn-out Note 20 Ultra battery
- Runtime with 120 Hz drops from 8 hours to 4 to 5 hours of screen time
- Sudden shutdown at 25 to 30 % remaining capacity
- Charging time from 0 to 100 % over 2.5 hours despite the original 25 W charger
- Back cover bulges slightly — battery already swollen
- During DeX use the Note 20 Ultra gets unusually hot
- Wireless charging detection becomes unreliable — battery delivers too little power
The Note 20 Ultra consumes more energy than the smaller Note 20 — 120 Hz curved AMOLED, larger chip, more intensive camera sensors. That is why battery wear sometimes reaches the noticeable range as early as after 3 years. See our Note 20 Ultra repair overview.
How the Note 20 Ultra battery replacement works
- Battery measurement with professional equipment
We read out the current capacity — usually between 60 and 75 %. We also check USB-C, the wireless charging coil and the charging logic on the mainboard to rule out other causes.
- Opening the IP68 adhesive ring
At 65 °C we release the water-protection adhesive ring in a controlled way. The Armor Aluminum housing stays free of distortion. The S Pen digitizer flex is protected while opening.
- Old cell out, new one in
The battery is fixed to the mid-frame with pull tabs. We release it without pressure on the mainboard or wireless coil. The new 4500 mAh cell is fitted and connected to the mainboard.
- Renew IP seal, charge test, handover
New IP68 adhesive ring, back cover refitted. 15 minutes of 25 W charge test, wireless charging test. After around 100 minutes your Note 20 Ultra is ready.
Reparo works without customer access — pickup service in Vienna or insured send-in service from all of Austria.
Ultra battery replacement vs. S24 Ultra new purchase
89 € battery replacement vs. 420 € used Note 20 Ultra vs. 1,050 € S24 Ultra. With an intact display, S Pen and camera the battery replacement beats every alternative. Only when several components have failed at the same time does a new purchase make sense.
Important to know: during the battery replacement we renew the IP68 adhesive ring — legally the Samsung IP certification expires anyway. Splash water remains no problem, avoid submerging after the procedure.
How do you protect the new battery?
Do not charge to 100 % every night, do not run permanently down to 0 %. The 20 to 80 % range is ideal. Keep Adaptive Battery enabled in the settings. With this treatment you will last another 3 to 4 years.
15 questions about the Note 20 Ultra battery replacement
What does the Note 20 Ultra battery replacement cost in Vienna?
89 € fixed price. Included: new 4500 mAh cell, installation with S Pen protection, new IP seal, charge test, 6 months warranty. The 25 € diagnostic check is waived.
How long does the replacement take?
Around 100 minutes. Longer than a standard Galaxy because of the IP seal and curved housing. In Vienna same-day with pickup service.
Original Samsung battery or quality replacement part?
Original batteries for the Note 20 Ultra have been barely available since 2024. We use certified quality replacement parts with 4500 mAh, 3.87 V and an identical charge curve.
Does the S Pen work after the battery replacement?
Yes. The S Pen digitizer sits under the display and is not touched during the battery replacement. Pressure sensitivity and tilt detection are preserved.
Are all data and Samsung Notes preserved?
Yes, completely. The flash memory is not touched. Samsung Notes with S Pen sketches, WhatsApp, photos and the DeX configuration stay unchanged.
Does wireless charging still work after the swap?
Yes. The wireless coil is not replaced during the battery swap. With a new battery wireless charging works as usual — even better, because there is no more voltage shortage.
Note 20 Ultra shuts down at 30 % — is it the battery?
Most likely yes. Cell drift distorts the capacity display — the cell is actually already empty even though the screen shows 30 %.
How long does the new battery last?
500 to 800 complete charge cycles down to under 80 % capacity. For DeX power users 2 to 3 years, for normal users 4 years or more.
Note 20 Ultra bulges at the back — is it urgent?
Yes, stop charging immediately. A swollen battery can permanently damage the S Pen digitizer and the curved display. Book a pickup.
Can I drop by with the Note 20 Ultra?
No. Reparo works without customer access. Courier in Vienna or postal send-in service from the federal states — both included in the price.
How exactly does the Vienna pickup service work?
Book an appointment online, time window 9 to 18, give the address. Courier to all 23 districts, return delivery usually the same day.
Send-in from Styria, Carinthia, Salzburg — is it safe?
Yes. Shipping instructions by email, send it padded and insured. Insured return shipping is also included.
How long is the warranty valid?
6 months on the battery and installation work. In case of capacity loss or charging fault, a free second replacement. Mechanical damage is not covered.
Is the Note 20 Ultra battery replacement worth it in 2026?
Yes. The device is still technically at premium level. 89 € against 1,050 € for an S24 Ultra — a clear case for everyone who does not need a top flagship.
Replace battery and display together — is that better?
Yes, more efficient. Both procedures require opening the IP68 adhesive. A combined price for the battery plus the screen replacement saves working time.
