Typical battery problems on the POCO M4 Pro 4G
- Your POCO M4 Pro 4G no longer lasts a working day – it used to easily reach 6 to 8 hours of screen-on time
- The phone suddenly shuts off at 25 to 35% remaining charge and only comes back on once it's plugged in
- Fast charging at 33W now triggers temperature warnings and a reduced charging speed
- The battery percentage jumps in big steps (65% → 35% → 10%) instead of falling steadily
- You can see a gap between the frame and the back cover: the classic sign of a swollen cell
- The POCO M4 Pro 4G no longer starts after fully draining, even after a long charge
- MIUI shows a clearly reduced maximum capacity in the battery settings
How does the POCO M4 Pro 4G battery replacement work?
- Battery diagnosis via MIUI + meter
MIUI settings → Battery → Health shows the capacity. Our voltage and impedance measurement on the battery module confirms the result. With capacity below 80% or a cycle count above 500, we recommend a replacement.
- Open the back cover gently
The POCO M4 Pro 4G is opened with a special suction cup and a warmed adhesive edge. The back cover is lifted off carefully, 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 isopropyl alcohol 99 – never using screwdrivers as a lever.
- Fit the certified 5000-mAh cell
A new Li-Polymer cell with identical capacity, 3.87 V nominal voltage and an exact-fit form factor. The connector goes onto the mainboard, the adhesive onto the frame, and the contact pressure is controlled.
- Re-sealing + gasket
Old adhesive film removed, fresh Xiaomi adhesive applied, back cover bonded again under pressure. 30 minutes of curing time.
- Full charge + calibration
First charge to 100% at 25 °C – MIUI recalibrates the battery gauge to the new cell. We check the battery health and 33W charging.

What does the battery replacement cost for the POCO M4 Pro 4G?

How long does the new POCO M4 Pro 4G battery last?
With normal use the replacement battery lasts 500 to 700 full cycles while keeping at least 80% capacity – roughly 2.5 to 3.5 years of everyday use. One full cycle equals a complete discharge from 100% to 0%. The warranty covers the cell and the fitting for 6 months.
Is the 5000-mAh battery for the POCO M4 Pro 4G a standard replacement or original?
We fit certified 5000-mAh cells built to Xiaomi's original specification: 3.87 V nominal voltage, identical capacity, the same charging curve. Original Xiaomi service packs are only available through authorised Xiaomi service centres. Our cells last measurably just as long.
Does 33W Turbocharge work on the POCO M4 Pro 4G after the replacement?
Yes. The 33W Turbocharge electronics sit on the POCO M4 Pro 4G mainboard, not in the battery. Our replacement cell supports the full charging protocol and charges with original Xiaomi adapters in the same time as before. The cell chemistry is designed for high-current charging.
Does the POCO M4 Pro 4G have wireless charging?
No. By design the POCO M4 Pro 4G has no wireless charging – Xiaomi leaves out the Qi coil in this class to optimise price and weight. Charging works exclusively via USB-C at up to 33W.
My POCO M4 Pro 4G is bulging at the back – is that dangerous?
Yes, potentially. A swollen battery has built up gas pressure (the cell chemistry is at the end of its life) – a fire and explosion risk, especially in heat. Bring it to us right away: hazardous-goods disposal handled directly by Reparo, replacement for EUR 49. Until then, don't keep charging it or leave it in the sun.
Will the display be damaged during the POCO M4 Pro 4G battery replacement?
No, not with us. We open the POCO M4 Pro 4G from the back, so the display stays untouched. With the plastic build we control the heat especially carefully so the plastic frame doesn't warp.
Can I drop my POCO M4 Pro 4G off directly at Reparo?
Reparo has no walk-in counter for customers. You book an appointment online – our courier comes to your address in all 23 Vienna districts. From the rest of Austria there's insured shipping, with the return included in the price.
How does the pickup service in Vienna for the POCO M4 Pro 4G battery replacement work?
Book online, pick a time slot between 9 am and 6 pm, and the courier drives to your Vienna address (1st district through to the 23rd, Liesing). The battery replacement takes 60 to 90 minutes in the studio, and the phone often comes back the same day. The courier is included in the EUR 49 fixed price.
Is shipping from the rest of Austria safe for a POCO M4 Pro 4G battery?
Yes. Battery shipping falls under hazardous-goods class 9 – we send a UN-approved shipping box. The POCO M4 Pro 4G travels to Vienna insured and goes back the same way after the replacement. We regularly help customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Will I lose data during the POCO M4 Pro 4G battery replacement?
No. The flash storage, Mi account and SIM card are not disconnected during a battery replacement. Photos, WhatsApp chats, apps and settings all stay fully intact. A Mi Cloud backup is still recommended before any repair.
How long is the warranty on the new POCO M4 Pro 4G battery?
Six months on the battery cell and the fitting. If the cell loses more than 10% capacity within that time: a free replacement. Not covered are deep discharge from leaving the phone unused for months, or external force.
Do I lose the Xiaomi warranty by replacing the POCO M4 Pro 4G battery?
The original Xiaomi warranty (1 year) on the POCO M4 Pro 4G expired 4 years ago. If a manufacturer warranty is still running, it ends with repairs outside authorised workshops. Reparo warranty: 6 months from fitting on the cell and the labour.
Is a POCO M4 Pro 4G battery replacement still worth it in 2026?
Yes. A battery replacement at EUR 49 versus a used phone with a fresh battery from around 79 € – plus moving your data, setting up a new Mi account and losing app data. The POCO M4 Pro 4G still gets MIUI updates from Xiaomi, and the repair extends its life by 2 to 3 years.
