Typical battery problems on the POCO M4 Pro 5G
- Your POCO M4 Pro 5G no longer makes it through a working day – it used to easily reach 6-8 hours of screen-on time
- The phone shuts off suddenly at 25-35% remaining and only comes back on once you plug it in
- While charging at 33W you can feel the back of the POCO M4 Pro 5G getting hotter than it used to
- The battery reads 40% and two minutes later the display jumps to 18% — the battery gauge is out of calibration
- The back panel bulges around the battery area – a visible swelling after deep discharge
- The POCO M4 Pro 5G no longer powers on after a full discharge, even after a long charge
- MIUI shows a clearly reduced maximum capacity in the battery settings
How the POCO M4 Pro 5G battery replacement works
- Battery diagnosis via MIUI + meter
MIUI settings → Battery → Health shows the capacity. Our voltage and impedance reading on the battery module confirms the result. At < 80 % capacity, or more than 500 cycles, we recommend a replacement.
- Opening the back panel carefully
The POCO M4 Pro 5G is opened with a special suction cup and a warmed adhesive edge. The back panel is lifted off gently, without warping the plastic frame.
- Releasing 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 a screwdriver as a lever.
- Fitting a certified 5000 mAh cell
A new Li-Polymer cell with identical capacity, 3.87 V nominal voltage and an exact form factor. Connector to the mainboard, adhesive to the frame, contact pressure controlled.
- Re-sealing + gasket
Old adhesive film removed, fresh Xiaomi adhesive applied, back panel bonded under pressure again. 30 minutes of curing time.
- Full charge + calibration
First charge to 100 % at 25 °C – MIUI re-calibrates the battery gauge to the new cell. We check battery health and 33W charging.
Replacing the POCO M4 Pro 5G battery – price, process and charging tech in Vienna
The POCO M4 Pro 5G holds a Li-Polymer cell with 5000 mAh of gross capacity. The chipset is efficient, but the battery ages all the same – chemically, every lithium cell loses roughly 0.05 to 0.1 percent of capacity per full cycle. Five-year-old phones often show MIUI readings between 70 and 82 percent.

With normal use the replacement battery lasts 500-700 full cycles at a minimum of 80 % capacity – roughly 2.5 to 3.5 years of everyday use. A full cycle equals a complete discharge from 100 % to 0 %. The warranty covers cell and fitting for 6 months.
Is the 5000 mAh battery for the POCO M4 Pro 5G a standard replacement or original?
We fit certified 5000 mAh battery cells to Xiaomi original specification: 3.87 V nominal voltage, identical capacity, the same charge curve. Original Xiaomi service packs are only available through authorised Xiaomi service centres. Our cells last measurably just as long.
Does 33W Turbocharge still work on the POCO M4 Pro 5G after the swap?
Yes. The 33W Turbocharge electronics sit on the POCO M4 Pro 5G mainboard, not in the battery. Our replacement cell supports the full charge 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 5G have wireless charging?
No. By design the POCO M4 Pro 5G has no wireless charging – Xiaomi leaves out the Qi coil in this class to save cost and weight. Charging works exclusively via USB-C at up to 33W.
My POCO M4 Pro 5G is bulging at the back – is that dangerous?
Yes, potentially. A swollen battery has built up gas pressure (cell chemistry at its end) – a fire and explosion risk, especially in heat. Bring it to us straight away: dangerous-goods disposal handled directly by Reparo, replacement for EUR 49. Until then, do not keep charging it or leave it in the sun.
Is the screen damaged during the POCO M4 Pro 5G battery replacement?
No, not with us. We open the POCO M4 Pro 5G from the back, so the screen stays untouched. With its plastic construction we manage the heat especially carefully so the plastic frame does not warp.

Is the send-in from the federal states safe for a POCO M4 Pro 5G battery?
Yes. Battery shipping falls under dangerous-goods class 9 – we send a UN-approved shipping box. The POCO M4 Pro 5G arrives in Vienna insured and goes back the same way after the swap. We regularly serve customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Is any data lost during the POCO M4 Pro 5G battery replacement?
No. Flash storage, Mi account and SIM card are not disconnected during the 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 5G battery?
Six months on the battery cell and fitting. If the cell loses more than 10 % capacity in that time: a free re-swap. Not covered are deep discharge from leaving it unused for months, or external force.
Do I lose the Xiaomi warranty through the POCO M4 Pro 5G battery replacement?
The Xiaomi original warranty (1 year) on the POCO M4 Pro 5G expired 4 years ago. If the manufacturer warranty is still running, it ends with repairs outside authorised workshops. Reparo warranty: 6 months from fitting on cell and labour.
Is the POCO M4 Pro 5G battery replacement still worth it in 2026?
Yes. Battery replacement EUR 49 vs. 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 5G still gets MIUI updates from Xiaomi, and the repair extends its life by 2-3 years.
