Google Pixel 4 XL Battery Replacement Vienna

The battery replacement on the Google Pixel 4 XL costs a fixed EUR 69. Included in the price: a certified 3,700 mAh battery cell, fitting, IP68 seal renewal, a charge test and a 6-month warranty. Diagnostic check 25 EUR — waived once you go ahead with the repair.

Yes, a swollen lithium-ion battery is a serious safety risk. The cell can leak, damage the screen through internal pressure or, in extreme cases, trigger thermal runaway. Stop charging the device, don't put it in your pocket and contact us immediately. We collect the same day in Vienna and replace the cell promptly.

Express in 1–2 hours. On the Pixel 4 XL the glass back has to be released first — that adds a little effort compared to older models. With pickup in Vienna it's usually back the same day, and 1–3 business days by post.

Yes. We renew the waterproof adhesive seal during reassembly, so the IP68 protection is restored after the repair. After intense water immersion we still recommend caution — on a 4-year-old device the seal ages faster anyway.

A full 100 % — identical to the original factory performance of 3,700 mAh. That means the Pixel 4 XL lasts a full day again under normal use, and even longer depending on screen brightness and the 90 Hz mode.

Original Google batteries are practically no longer available on the open market for the Pixel 4 XL — the model was discontinued in 2022. We fit certified compatible cells with the same 3,700 mAh capacity. In practice the runtime is the same, and safety is guaranteed by the pre-fitting test.

When the cell has aged, the internal resistance drifts significantly — the system thinks there's still 30 % energy left, but in reality the voltage is no longer enough. To protect itself the device shuts down unexpectedly. A battery swap solves this permanently, because the new cell keeps the voltage linear again.

No, Reparo has no walk-in. You book an appointment and we collect the Pixel 4 XL by pickup service in Vienna. With a swollen battery the rule is: don't transport the device yourself — we come directly to you and take it away in a controlled way.

You book a time slot online, we come to the address you give — home, office or café. With a swollen battery we transport the device in a fireproof lithium box. After the swap we bring the Pixel 4 XL back to you fully repaired.

Yes. With a swollen battery please pad the device especially well and label it clearly — no pressure on the screen or back. We recommend insured shipping. Repair and return run within 1–3 business days.

Yes, the battery is physically completely separate from the internal storage. Photos, apps, accounts, messages and settings stay untouched. We generally recommend a cloud backup, but it has nothing to do with the repair itself.

Reparo covers the fitted battery and the labour for 6 months. If the cell shows defects within that time — voltage drop, premature capacity loss, failure — we replace it free of charge. Mechanical damage from a drop or liquid ingress is not covered.

The diagnosis costs 25 EUR and includes a battery health check, a visual mainboard inspection and a function report. As soon as you place the repair order, the diagnosis fee is waived — you only pay the EUR 69 for the battery swap.

The Pixel 8a costs from EUR 549 — the battery swap is EUR 69. If the Pixel 4 XL otherwise works perfectly (screen, camera, charging port fine), the repair is clearly cheaper. With a swollen battery there's an extra factor: repairing now prevents larger follow-on damage, and a new purchase can wait.

With liquid ingress we first check whether the charging electronics are corroded — otherwise the new battery quickly destroys the mainboard again. We run a separate diagnosis (25 EUR, waived on repair) and then discuss the approach. The Pixel 4 XL does have IP68, but after 4 years the seal is often worn out.
