CMF Phone 2 Pro Battery Replacement Vienna – from 79 €
The battery in the CMF Phone 2 Pro is identical to its predecessor at 5,000 mAh. Because of the brighter display and the new processor, however, the device draws a bit more power — so wear shows up earlier accordingly. Typical signs: heat build-up during fast charging or sudden battery jumps. 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 on the CMF Phone 2 Pro
These signs clearly point to a battery replacement — not to a software tweak.
Runtime under 6 hours
Your CMF Phone 2 Pro 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 a double-digit charge level
The device shows 30 %, then suddenly drops to 0 and switches off. A classic sign of a worn-out battery cell that collapses under load.
Bulge under the back cover
You see a bulge through the modular back cover with telephoto camera module, or the frame looks slightly bent outward — act immediately. Swollen batteries are a safety risk.
Heat build-up while charging
The back gets hot during fast charging (over 42 degrees). A damaged cell generates more heat than a healthy one — which speeds up wear even further.
Nothing OS reports a battery warning
Nothing OS shows a noticeable capacity loss in the battery settings. At values below 80 percent, Nothing itself also recommends a battery replacement.
Charging time doubled
Your CMF Phone 2 Pro 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 CMF Phone 2 Pro battery replacement works
Clearly structured — from the appointment to the Glyph-tested return shipping.
Book an appointment or call
When booking, you tell us which symptom you are observing. We confirm the fixed price of 79 € before the repair.
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
With the modular back cover with telephoto camera module, the back is carefully detached. The 5,000 mAh cell is separated from adhesive and contacts — the Glyph Interface stays untouched.
Fit the new cell and calibrate
The new 5,000 mAh battery cell is inserted and the contacts secured. Nothing OS recognises the new battery and resets the battery health indicator to 100 percent.
Glyph test and return
We check every Glyph LED zone, test the charging performance and battery health. Return shipping or pickup in Vienna, 6 months warranty.
CMF Phone 2 Pro battery replacement — is it worth it?
| Option | Price | Assessment |
|---|---|---|
| Battery replacement at Reparo | 79 € | 5,000 mAh original capacity, data stays |
| Used CMF Phone 2 Pro purchase | from 180 € | Uncertain battery condition on the second-hand device |
| New CMF Phone 2 Pro or successor | from 329 € | Data transfer required, more expensive |
A battery replacement for 79 € brings your CMF Phone 2 Pro back to full runtime. Far cheaper than buying new — and you keep the device, your data and your Glyph settings.
Which battery cell does Reparo fit in the CMF Phone 2 Pro?
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 a traceable origin.
After installation, Nothing OS automatically recognises the new cell. The battery health indicator in the settings shows 100 percent again — with no hint of a replacement.
CMF Phone 2 Pro battery change — what you should know
The battery in the CMF Phone 2 Pro has 5,000 mAh capacity and is designed for around 800 to 1,000 full charge cycles. After two to three years of intensive use, the capacity is often down to just 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?
With the modular back cover with telephoto camera module, opening it without tools is tricky. Damage to the Glyph LED connections, broken 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 at 100 percent health — no warning remains, no restrictions on functions.
Pickup service vs. send-in
In Vienna, our courier service comes to you — the time window is arranged when you book. From the rest of Austria it goes by post. Well packed, the device reaches us within one working day.
Frequently asked questions — CMF Phone 2 Pro battery replacement
Does the CMF Phone 2 Pro battery differ from the regular Phone 2a?
Different cell, same rated capacity. The 2 Pro needs its specific cell — a Phone 2a battery would not fit without adapting the charge control.
Modular back — is the battery replacement cheaper here than on the Nothing Phone?
Yes. The modular back cover makes access easier, which is why we charge 59 euros instead of 69 euros as on the main Phone models.
Does the CMF Phone 2 Pro have wireless charging?
No — the CMF Phone 2 Pro does without wireless charging. The battery replacement test routine therefore focuses only on wired fast charging at 33 W.
What exactly does the battery replacement on the CMF Phone 2 Pro cost?
79 € fixed price. Includes the 5,000 mAh cell, installation, Glyph test, charging performance check and 6 months warranty. The diagnostic check (25 EUR) is waived on repair.
How long does the battery replacement take?
About 2 hours in the workshop for the procedure plus the Glyph test. With pickup service in Vienna, done on the same or next working day. With send-in from Austria, 1 to 3 working days including return shipping.
Will my data be lost during the battery replacement?
No. A battery replacement touches neither the storage nor the operating system. Apps, photos, contacts, Glyph profiles and Nothing OS settings are fully retained.
Can I drop off my CMF Phone 2 Pro?
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 arise in that period, 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 EUR. This amount is fully waived if you then commission the repair with us. We check the battery, charging function and Glyph Interface and tell you specifically what needs to be replaced.
How does the pickup service in Vienna work?
After booking, we arrange a pickup time at your address. We take the device with us, repair it in our workshop and bring it back — all from a single source.
How do I send in my CMF Phone 2 Pro from Austria?
Send it in a padded box or well-cushioned packaging by post to our address in Vienna 1020. Once received, we confirm the order and send the repaired device back 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 ignite. Please do not keep charging or heavily loading 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 indicator 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 CMF Phone 2 Pro?
Yes, in most cases. A 79 € battery replacement against 119 € for a new display or 329 € for a used successor device — the maths clearly favours the replacement if the rest of the device works.
