Typical battery problems on the POCO X4 GT
- Your POCO X4 GT no longer lasts a working day – you used to get 6–8 hours of screen-on time easily
- The phone suddenly shuts off at 25–35% remaining and only comes back on once plugged in
- Fast charging at 67W now triggers temperature warnings and a reduced charging speed
- The percentage reading is unreliable — it shows 50%, and three minutes later the phone is at 20%
- The POCO X4 GT no longer lies flat on the table — the back bulges slightly in the middle
- The POCO X4 GT won't start after fully draining, not even after a long charge
- MIUI/HyperOS shows a clearly reduced maximum capacity in the battery settings
How does the POCO X4 GT battery replacement work?
- Battery diagnosis via MIUI/HyperOS + measuring device
MIUI/HyperOS settings → Battery → Health shows the capacity. Our voltage/impedance measurement on the battery module confirms the finding. Below 80% capacity or a cycle count above 500, we recommend the swap.
- Carefully open the back
The POCO X4 GT 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 held to the plastic frame with pull tabs. We loosen the adhesive strips with isopropanol-99 – never using screwdrivers as a lever.
- Fit the certified 5080 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, contact pressure controlled.
- Re-bonding + seal
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 – MIUI/HyperOS recalibrates the battery gauge to the new cell. We check battery health and 67W charging.
POCO X4 GT battery replacement – price, process and charging tech in Vienna
On the POCO X4 GT the 5080 mAh cell is bonded inside the plastic frame. Xiaomi specifies 500 charge cycles as the service life, after which the capacity may fall below 80%. In practice that means: after two to three years of everyday use the wear becomes noticeable – the battery reading turns inaccurate, fast charging throttles, standby losses rise.

How long does the new POCO X4 GT battery last?
With normal use the replacement battery lasts 500–700 full cycles with 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 runs 6 months on the cell and fitting.
Is the 5080 mAh battery on the POCO X4 GT a standard replacement or original?
We fit certified 5080 mAh battery cells to Xiaomi original spec: 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 the same.
Does 67W Turbocharge still work on the POCO X4 GT after the swap?
Yes. The 67W Turbocharge electronics sit on the POCO X4 GT mainboard, not in the battery. Our replacement cell supports the full charging protocol and charges in the same time as before with original Xiaomi power supplies. The cell chemistry is designed for high-current charging.
Does the POCO X4 GT support wireless charging?
No. By design the POCO X4 GT has no wireless charging – Xiaomi leaves out the Qi coil in this class to optimise price and weight. Charging works exclusively over USB-C with up to 67W.
My POCO X4 GT 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. Come to us straight away: hazardous-waste disposal directly by Reparo, swap for EUR 59. Until then, don't keep charging the device or leave it in the sun.
Will the display get damaged during the POCO X4 GT battery replacement?
No, not with us. We open the POCO X4 GT from the back, the display stays untouched. With this plastic build we monitor the heat management especially carefully so the plastic frame does not warp.
Can I just drop my POCO X4 GT off at Reparo?
Reparo has no on-site customer access. You book an appointment online – our courier comes to your address in all 23 Vienna districts. From the provinces, insured shipping, with return included in the price.
How does the pickup service in Vienna work for the POCO X4 GT battery replacement?
Book online, choose a time slot between 9 and 18, the courier comes to your Vienna address (1st district to the 23rd, Liesing). Battery swap 60–90 minutes in the studio, often returned the same day. Courier included in the fixed EUR 59.
Is shipping from the provinces safe for a POCO X4 GT battery?
Yes. Battery shipping falls under hazardous-goods class 9 – we send a UN-approved shipping box. The POCO X4 GT travels to 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 X4 GT battery replacement?
No. The flash storage, Mi account and SIM card are not disconnected during the battery swap. 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 X4 GT battery?
Six months on the battery cell and the fitting. If the cell loses more than 10% capacity in that time: a free re-swap. Not covered are deep discharge from months of being left unused or external force.
Do I lose the Xiaomi warranty through the POCO X4 GT battery replacement?
The original Xiaomi warranty (1 year) on the POCO X4 GT expired 3 years ago. With a manufacturer warranty still running, it ends through repairs outside authorised workshops. Reparo warranty: 6 months from fitting on the cell and the labour.
Is the POCO X4 GT battery replacement still worth it in 2026?
Yes. A battery swap at EUR 59 vs. a used device with a fresh battery from about EUR 149 – plus the data move, a new Mi account setup, lost app data. The POCO X4 GT is still supported by Xiaomi with MIUI/HyperOS updates, and the repair extends its life by 2–3 years.
