Samsung Galaxy S22 Plus 5G EB-BS906ABY Replacement Battery 3.88V 4000mAh

Up to 21% off
New arrival
From $26.99 USD $33.99
Shipping calculated at checkout.
Fits Samsung Galaxy S22 Plus 5G, replaces OEM battery part numbers EB-BS906ABY and GH82-27502A.
3.88V nominal, 4000mAh capacity delivers full processor and display power on a single charge cycle.
Connector slides vertically into the battery slot with no locking tab—orientation marked on the cell housing.
We bench-tested the EB-BS906ABY against the fuel gauge IC; BMS reported full capacity on first charge cycle without throttling.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the coulomb counter recalibrates to the new cell's discharge curve.

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.

Samsung Galaxy S22 Plus 5G — 3.88V Li-Polymer Replacement Battery (EB-BS906ABY)

This is a 3.88V, 4000mAh Li-Polymer replacement battery for the Samsung Galaxy S22 Plus 5G and S22+ 5G. It fits SM-S906B and SM-S906B/DS variants and slots into the original battery bay using the same connector and form factor. Capacity is 4000mAh (15.52Wh), matching the OEM cell specification.

  • SM-S906B series fit: All SM-S906B variants share the same voltage rail, battery connector pinout, and BMS handshake protocol. This cell communicates correctly with the Galaxy S22 Plus 5G charge IC and fuel gauge IC without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an SM-S906B unit. The BMS accepted the cell on first connection, charge termination triggered at the correct cutoff voltage, and the fuel gauge IC began tracking coulomb count within the first full cycle.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging and complete one full discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before fast charging pushes high current into an uncalibrated cell.

Sudden shutdown at 20–30% on the Galaxy S22 Plus 5G after a cell swap

The S22 Plus 5G runs a Snapdragon 8 Gen 1 modem and a 6.6-inch AMOLED panel simultaneously. Under that combined load, a cell with a degraded or uncalibrated discharge curve hits a voltage cliff faster than the fuel gauge IC predicts. The phone interprets the sudden voltage drop as a critical low and shuts down even though the reported percentage still shows 20–30%. One full slow discharge-charge cycle after replacement recalibrates the coulomb counter and resolves most premature shutdowns.

Phone won't power on after the replacement battery sat in storage

Li-Polymer cells shipped or stored for extended periods can self-discharge below 2.5V per cell, triggering a BMS lockout that prevents the phone from powering on or showing a charge indicator. Connect to a 5W or 10W charger — not a fast charger — and leave it for 20–30 minutes without attempting to power on. The charge IC will trickle current into the cell until voltage recovers above the BMS re-enable threshold, typically around 3.0V, at which point normal charging resumes.

Frequently Asked Questions

The Galaxy S22 Plus 5G shuts off at around 25% after I fitted the new battery — is the cell faulty?

The cell is almost certainly fine. The fuel gauge IC is still using the discharge curve it mapped for the old, degraded cell, so it misreads the voltage cliff on the new cell and triggers an emergency shutdown earlier than it should. Run one complete discharge down to automatic shutdown, then charge fully at standard speed with fast charging disabled. After that single calibration cycle, the coulomb counter resets to the new cell's curve and premature shutdowns stop.

Fast charging stopped working the first time I plugged in after replacing the battery — USB-PD shows standard charge only.

This is normal on the first connection. The S22 Plus 5G charge IC runs a handshake with the BMS before stepping up to fast charge current, and on a fresh cell that handshake sometimes fails or defaults to the lowest safe current tier. Complete one full charge at standard rate, disconnect, and reconnect. On the second session the USB-PD negotiation completes correctly and fast charging resumes — no hardware fault involved.

The battery percentage keeps jumping — goes from 60% down to 44% in seconds, then back up.

Erratic percentage jumps mean the fuel gauge IC is actively recalibrating and has not yet built a stable model of the new cell's internal resistance across its state-of-charge range. This typically settles after two to three full discharge-charge cycles. Keep fast charging off during those cycles so the IC can measure the cell's voltage response at steady, predictable current. After the third full cycle, if jumping continues, check that the battery connector is fully seated — a loose pin causes intermittent voltage readings that the fuel gauge IC cannot correct for.
