The 5,000 mAh battery in the Phone 3a is built to last a full day of use.

Reparo replaces the 5,000 mAh battery in Vienna – fixed price 79 €, Nothing OS recognises the new cell, Glyph interface test included. Pickup service in Vienna or send-in from across Austria.

Typical battery problems with the Nothing Phone 3a
These signs clearly call for a battery replacement — not a software optimisation.
Runtime under 6 hours
Your Nothing Phone 3a no longer lasts half a working day? The cell has been through too many charge cycles. A replacement restores the usage time — with 5,000 mAh typically a full day.
Shutdown at double-digit charge level
The device shows 30 %, but suddenly drops to 0 and switches off. A classic sign of a worn battery cell that collapses under load.
Bulge under the back cover
You see a bulge through the design back cover with optimised Glyph Light, or the frame seems slightly bent open — act immediately. Swollen batteries are a safety risk.
Heat build-up during charging
The back gets hot during fast charging (over 42 degrees). A damaged cell generates more heat than a healthy one — which further accelerates wear.
Nothing OS reports a battery warning
Nothing OS shows a noticeable loss of capacity in the battery settings. At values below 80 percent, even Nothing itself recommends a battery replacement.
Charging time doubled
Your Nothing Phone 3a now takes 2 or 3 hours where it used to need 60 minutes? The charging behaviour is impaired — typical of an aged cell.
How the Nothing Phone 3a battery replacement works
Clearly structured — from the appointment to the Glyph-tested return shipment.
Book an appointment or call
You describe the behaviour to us — the battery weakens after long sessions on the 70 mm periscope telephoto, or the device stays much longer on the 50 W charger. We confirm the 79 € fixed price and, after the replacement, fully recalibrate the optimised Glyph Light.
Pickup in Vienna or send-in
In Vienna our pickup service comes directly to you. From across Austria you send the device by post to our workshop in Vienna 1020.
Open the back cover and remove the battery
On the design back cover with optimised Glyph Light, the back is carefully released. The 5,000 mAh cell is separated from adhesive and contacts — the Glyph Interface stays untouched.
Insert and calibrate the new cell
The new 5,000 mAh battery cell is inserted and the contacts are secured. Nothing OS recognises the new battery and resets the battery health display to 100 percent.
Glyph test and return
We check every Glyph LED zone, test the charging performance and battery health. Return shipment or pickup in Vienna, 6 months warranty.
Nothing Phone 3a battery replacement — is it worth it?
| Option | Price | Assessment |
|---|---|---|
| Battery replacement at Reparo | 79 € | 5,000 mAh original capacity, data stays |
| Used Nothing Phone 3a purchase | from 180 € | Uncertain battery condition on the previous device |
| New Nothing Phone 3a or successor | from 329 € | Data transfer needed, more expensive |
A battery replacement for 79 € brings your Nothing Phone 3a back to full runtime. Considerably cheaper than buying new — and you keep your device, data and Glyph settings.
Which battery cell does Reparo fit in the Nothing Phone 3a?
We replace it with a 5,000 mAh cell with identical specification to the original. The charging characteristics, temperature monitoring and health values match the factory-fitted unit.
The cells come from authorised suppliers and are certified to common safety standards — no no-name cells without traceable origin.
After installation, Nothing OS automatically recognises the new cell. The battery health display in the settings shows 100 percent again — with no indication of a replacement.
Replacing the Nothing Phone 3a battery — what you should know
The battery in the Nothing Phone 3a has 5,000 mAh capacity and is designed for about 800 to 1,000 full charge cycles. After two to three years of intensive use, the capacity is often only around 75 to 80 percent — noticeable, but not critical. It becomes critical when the cell swells or the device shuts down spontaneously.
Why no DIY battery replacement?
On the design back cover with optimised Glyph Light, opening it without tools is tricky. Damage to the Glyph LED connections, cracked glass or wrongly calibrated cells are common consequences. A professional replacement costs 79 € — a failed DIY attempt quickly costs more.
Nothing OS and battery health
Nothing OS continuously reads temperature, charge level and cell health. After a battery replacement, the system shows the new cell with 100 percent health — no warning remains, no restrictions in functions.
Pickup service vs. send-in
In Vienna our courier service comes to you — the time slot is arranged when you book the appointment. From the rest of Austria it goes by post. Well packed, the device reaches us within one working day.
Frequently asked questions — Nothing Phone 3a battery replacement
What exactly does the battery replacement on the Phone 3a cost?
79 euros including installation, Glyph test and 6 months warranty. The diagnostic check (25 euros) is waived on a repair order.
Fast charging at 50 W — does it work after the replacement?
Yes. The 50 W charging function is fully retained after the battery replacement. Reparo tests the charging performance in the final test with an original Nothing power adapter.
IP64 on the Phone 3a — is it lost after the battery replacement?
The dust and splash protection is largely restored by a professional replacement. We fit new seals on the battery cover. Full IP certification, however, can only be re-issued at the manufacturer's plant.
What exactly does the battery replacement on the Nothing Phone 3a cost?
79 € fixed price. Includes the 5,000 mAh cell, installation, Glyph test, charging performance check and 6 months warranty. The diagnostic check (25 €) is waived on a repair order.
How long does the battery replacement take?
About 2 hours in the workshop for the procedure plus the Glyph test. With the pickup service in Vienna, done on the same or next working day. With send-in from across Austria, 1 to 3 working days including return shipping.
Will my data be lost during the battery replacement?
No. A battery replacement touches neither storage nor operating system. Apps, photos, contacts, Glyph profiles and Nothing OS settings are fully preserved.
Can I drop off my Nothing Phone 3a in person?
Reparo has no walk-in. In Vienna our pickup service comes to you. From all of Austria you send your device by post to our workshop in Vienna 1020.
Is there a warranty on the new battery?
Yes, 6 months warranty on the battery cell and the installation. If problems occur during this time, we replace it free of charge.
Does Reparo fit original or aftermarket batteries?
We use battery cells with identical capacity and charging characteristics to the original. Through authorised suppliers we source cells that reach the same safety standard as the factory-fitted original.
What does the diagnosis cost if it is unclear whether the battery is to blame?
25 €. This amount is fully waived if you then commission the repair with us. We check the battery, charging function, Glyph Interface and tell you exactly what needs to be replaced.
How does the pickup service in Vienna work?
After booking the appointment we arrange a pickup time at your address. We take the device, repair it in our workshop and bring it back — all from a single source.
How do I send in my Nothing Phone 3a from Austria?
Send it in a padded box or well-cushioned packaging by post to our address in Vienna 1020. On arrival we confirm the order and return the repaired device within a few working days.
My battery is swelling — is that dangerous?
Yes. A swollen battery (recognisable by bulges under the back cover) should be replaced immediately. Swollen lithium-ion cells can catch fire. Please do not keep charging or heavily stressing it — book an appointment as soon as possible.
Does Nothing OS show the correct battery health after the replacement?
Yes. After fitting the new cell, the battery health display in Nothing OS shows 100 percent again. The system recognises the replacement automatically and calibrates itself during the first charge.
Is a battery replacement worth it on an older Nothing Phone 3a?
It is clearly worth it. 79 € for a battery replacement versus 169 € for a new Phone 3a display or around 449 € for a used Phone (3a) — and you keep the periscope telephoto with 70 mm focal length, which the cheaper Phone (2a) did not yet have.
