Google Pixel 7 GZE8U Replacement Battery 3.86V 4250mAh

Google Pixel 7 (GVU6C / GQML3) — 3.86V Li-Polymer Replacement Battery (GZE8U)

This 3.86V, 4250mAh (16.41Wh) Li-Polymer battery replaces the OEM GZE8U cell inside the Google Pixel 7, including variants GVU6C and GQML3. It restores power to the display, Tensor G2 processor, and all connectivity radios. Physical dimensions are 92.80 × 47.40 × 5.30mm — match these against your original cell before installation.

• Pixel 7 / GVU6C / GQML3 platform fit: All three model codes share the same motherboard revision, battery connector pinout, and BMS communication protocol. One cell fits all three without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Pixel 7 platform. The BMS handshook correctly with Android's battery health service, and the coulomb counter tracked state-of-charge without fault flags on the first full cycle.
• First-cycle fast-charge tip: On the first use after installation, disable fast charging in Settings → Battery and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging is applied to an uncalibrated cell.

Sudden shutdown at 20–30% on the Pixel 7 after a cell swap

A new Li-Polymer cell has a slightly different internal resistance profile than the aged cell the fuel gauge IC spent months learning. Under peak modem load or screen-on burst draws, the phone's voltage rail sags faster than the gauge predicts — Android sees a valid state-of-charge reading right up until the cell can no longer sustain the voltage floor, then shuts down immediately. This is a calibration gap, not a faulty cell. Run one full discharge to below 10% followed by an uninterrupted charge to 100% with the screen off. After that single cycle, the coulomb counter resets its reference points against the new cell and the shutdowns stop.

USB-PD fast charge not accepted on the first cycle after replacement

After a cell swap, the Pixel 7's charge IC may reject the USB-PD handshake on the first plug-in and fall back to 5W standard charging. This happens because the BMS on a fresh cell starts in a conservative protection state until it logs a valid voltage window from the host charger. Use the original Google 30W USB-C charger or a certified USB-PD 3.0 adapter — third-party cables with passive resistors cannot complete the PD negotiation. Unplug and re-plug once after the phone reaches 15% charge; the BMS typically accepts the full fast-charge profile from that point onward.
