Typical battery problems on the POCO C75
- Your POCO C75 no longer lasts a working day – you used to easily reach 6-8 hours screen-on time
- The device suddenly switches off at 25-35% remaining charge and only turns on again when plugged in
- The POCO C75 gets warmer than before while charging – a sign of increased internal resistance in the old cell
- The percentage reading is unreliable — 50% is shown, 3 minutes later the device is at 20%
- The POCO C75 no longer lies flat on the table — the back bulges slightly in the middle
- The POCO C75 no longer starts after a complete discharge, not even after extended charging
- HyperOS shows a clearly reduced maximum capacity in the battery settings
How does the POCO C75 battery replacement work?
- Battery diagnosis via HyperOS + measuring device
HyperOS settings → Battery → Health shows the capacity. Our voltage/impedance measurement at the battery module confirms the finding. At < 80 % capacity or cycle count > 500 we recommend a replacement.
- Open the back carefully
The POCO C75 is opened with a special suction cup and a warmed adhesive edge. The back is lifted off gently, without warping the plastic frame.
- Release the old battery
The battery cell is fixed to the plastic frame with pull tabs. We loosen the adhesive strips with isopropanol-99 – never using screwdrivers as levers.
- Fit a certified 5160 mAh cell
New Li-polymer cell with identical capacity, 3.87 V nominal voltage, exact-fit form factor. Connector on the mainboard, adhesive on the frame, controlled contact pressure.
- Re-sealing + gasket
Old adhesive film removed, new Xiaomi adhesive applied, back re-bonded under pressure. 30 min curing time.
- Full charge + calibration
First charge to 100 % at 25 °C – HyperOS recalibrates the battery gauge to the new cell. We check battery health and 18W charging.

Is the 5160 mAh battery on the POCO C75 a standard replacement or original?
We fit certified 5160 mAh battery cells to Xiaomi original specification: 3.87 V nominal voltage, identical capacity, same charge curve. Original Xiaomi service packs are only available through authorised Xiaomi service centres. Our cells last measurably the same.
Does 18W fast charging work on the POCO C75 after the replacement?
Yes. The 18W fast-charging electronics sit on the mainboard of the POCO C75, not in the battery. Our replacement cell supports the full charge protocol and charges with original Xiaomi power supplies in the same time as before. The cell chemistry is designed for high-current charging.
Does the POCO C75 have wireless charging?
No. The POCO C75 has no wireless charging by design – Xiaomi omits the Qi coil in this class to optimise price and weight. Charging works exclusively via USB-C with up to 18W.
My POCO C75 is bulging at the back – is that dangerous?
Yes, potentially. A swollen battery has built up gas pressure (cell chemistry at its end) – fire and explosion risk, especially in heat. Come to us immediately: dangerous goods disposal directly by Reparo, replacement for €49. Until then do not keep charging the device or leave it in the sun.
Will the display be damaged during the POCO C75 battery replacement?
No, not with us. We open the POCO C75 from the back, the display stays untouched. With the plastic build we monitor the temperature control especially carefully so the plastic frame does not warp.

Is shipping from the federal states safe for a POCO C75 battery?
Yes. Battery shipping falls under dangerous goods class 9 – we send a UN-approved shipping box. The POCO C75 arrives in Vienna insured and goes back the same way after the replacement. Regular customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Is any data lost during the POCO C75 battery replacement?
No. Flash storage, Mi account and SIM card are not disconnected during the battery replacement. Photos, WhatsApp chats, apps and settings remain fully intact. A Mi Cloud backup is nonetheless recommended before any repair.
How long is the warranty on the new POCO C75 battery?
Six months on the battery cell and fitting. If the cell loses more than 10 % capacity in that time: free follow-up replacement. Not covered are deep discharge from months of disuse or external force.
Do I lose the Xiaomi warranty through the POCO C75 battery replacement?
The Xiaomi original warranty (1 year) on the POCO C75 expired 1 year ago. With a still-running manufacturer warranty, it lapses through repairs outside authorised workshops. Reparo warranty: 6 months from fitting on cell and labour.
Is the POCO C75 battery replacement still worth it in 2026?
Yes. Battery replacement €49 vs. a used device with a fresh battery from about €65 – plus data migration, new Mi account setup, lost app data. The POCO C75 is still supplied with HyperOS updates by Xiaomi, the repair extends the lifespan by 2-3 years.
