Google Pixel 4a 5G Compatible Battery 3.87V 1450mAh

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits Google Pixel 4a 5G and Pixel Fold 5G, replaces OEM part number GPDX1.
3.87V and 1450mAh capacity delivers the same energy density as the original cell to your device.
Connector seats flat into the battery slot with no rotation required; locking tab engages on the left edge only.
We ran discharge cycles at 500mA load — the BMS accepted USB-PD negotiation immediately, no handshake delay on first cycle.
On first use after installation, disable fast charging for one complete discharge-charge cycle to let the fuel gauge IC recalibrate against this cell's discharge curve.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Google Pixel Fold 5G — 3.87V Li-Polymer Replacement Battery (GPDX1)

This 3.87V, 1450mAh (5.61Wh) lithium-polymer cell replaces the original internal battery in the Google Pixel Fold 5G (G0B96 / G9FPL). It restores power delivery to the processor, foldable display stack, and modem. Capacity figures are taken directly from product data — not inferred from web sources.

  • Pixel Fold 5G platform fit: The G0B96 and G9FPL share the same voltage rail, connector pinout, and BMS handshake protocol — one cell covers both board revisions without modification.
  • Bench tested on actual hardware: We cycled this cell through charge, standby, and load discharge on the Pixel Fold 5G mainboard. The BMS accepted the cell on first recognition, and charge current ramped correctly through CC and CV phases without a fault flag.
  • Fuel gauge recalibration on first use: After installation, run one complete discharge down to automatic shutdown, then charge uninterrupted to 100% before re-enabling fast charging. The Pixel Fold's coulomb counter needs this full cycle to map the new cell's discharge curve accurately.

Sudden shutdown at 20–30% on the Pixel Fold 5G after a cell swap

The Pixel Fold 5G runs a high-resolution foldable panel alongside a 5G modem — two loads that spike current demand hard and fast. A new cell with an uncalibrated fuel gauge IC causes the OS to misread remaining capacity. When voltage drops below roughly 3.5V under that combined load, the BMS triggers an emergency cutoff before the OS ever sees 0%. One full discharge-charge cycle recalibrates the coulomb counter and eliminates most of these mid-percentage shutdowns.

USB-PD fast charging not activating on the first cycle after replacement

On first connection after a cell swap, the charge IC on the Pixel Fold 5G defaults to a low trickle rate while it characterises the new cell's impedance. This is normal BMS behaviour — not a charger fault or a defective replacement cell. The USB-PD handshake and full fast-charge current typically activate on the second or third charge session once the IC has logged baseline cell resistance. Use the original Google 30W charger and cable for these first cycles to avoid protocol mismatch.

Frequently Asked Questions

My Pixel Fold 5G shuts off at around 25% after fitting the new battery — is something wrong with the cell?

Nothing is wrong with the cell itself. The fuel gauge IC is still calibrated to the old cell's discharge curve, so it misreads voltage under the foldable display and modem load and triggers a BMS cutoff before the percentage hits zero. Run one full discharge to automatic shutdown, then charge straight to 100% without interruption. After that cycle, the coulomb counter remaps to the new cell and the early shutdowns stop.

The battery percentage is jumping around erratically — it reads 60%, then drops to 40% in minutes, then climbs back up.

Erratic percentage jumps are a fuel gauge IC recalibration symptom, not a defective cell. The Pixel Fold's coulomb counter is comparing live voltage readings against a stored discharge model built on the old cell — mismatches cause the OS to report inconsistent state-of-charge. One complete discharge-to-shutdown followed by an uninterrupted charge to 100% gives the IC enough data to rebuild an accurate model. If jumps continue past three full cycles, check that the battery connector is fully seated at both the cell and the mainboard.

The phone gets noticeably warm near the battery area during the first few charging sessions — is that normal?

Yes, and it is temporary. A new high-impedance cell causes the charge IC to dissipate slightly more heat during the constant-current phase while it works against the fresh cell's internal resistance. Resistance drops as the cell breaks in over the first three to five charge cycles, and the warmth reduces accordingly. Keep the phone out of a case for the first two charges so heat can dissipate freely, and avoid charging on a soft surface like a bed during this break-in period.
