Apple iPhone XR Replacement Battery 3500mAh 616-00471

Up to 21% off
New arrival
From $30.99 USD $38.99
Shipping calculated at checkout.
Fits iPhone XR models A2105, A2106, A2108 and replaces OEM part 616-00471.
3.8V, 3500mAh Li-Polymer cell restores full charge capacity on a device that reports depleted after 500+ cycles.
Connector clips into the internal slot with polarity marked on the pack—orientation is keyed and non-reversible.
We ran five full discharge cycles on the bench; the BMS accepted charge without delay and voltage held stable under sustained load.
On first use after installation, disable fast charging for one complete discharge-charge cycle—this lets the fuel gauge IC recalibrate against the new cell discharge curve before high-current charging resumes.

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.

Apple iPhone XR — 3.8V Li-Polymer Replacement Battery (616-00471)

This 3.8V, 3500mAh Li-Polymer battery replaces the original cell in the Apple iPhone XR, covering models A2105, A2106, A2108, and two additional regional variants. It matches the OEM dimensions at 101.00 × 44.65 × 4.25mm, fitting the factory tray without modification. Voltage and capacity match Apple's specification for this model line exactly.

  • iPhone XR and A21xx variants: All five model numbers in this family share the same battery bay geometry, flex connector pinout, and BMS handshake protocol. One cell covers the full regional lineup without adapter or modification.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on an iPhone XR unit, confirming the BMS accepted the cell, charge termination triggered correctly at 4.35V, and the fuel gauge IC initialised without error flags.
  • First-cycle fuel gauge recalibration: After installation, disable fast charging and run one complete discharge-to-charge cycle at standard 5W. The fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve — skipping this step can leave the percentage readout several points off until the IC self-corrects.

Sudden shutdown at 20–30% on the iPhone XR after a cell swap

This happens because the fuel gauge IC is still using the discharge curve it mapped to the old, degraded cell. The new cell has a steeper voltage cliff at low state-of-charge, and the IC misjudges remaining capacity. Under modem or display load, the cell voltage drops faster than the IC expects, triggering an emergency shutdown before the displayed percentage reaches zero. One full discharge-to-shutdown followed by a complete charge cycle lets the coulomb counter remap to the new cell curve — after that cycle, shutdowns at 20–30% stop.

iPhone XR reporting wrong battery percentage after replacement

The fuel gauge IC stores a learned discharge profile for the cell it has been tracking — replace the cell and the stored profile no longer matches the new chemistry curve. The result is percentage jumps, readings that stick at one number for too long, or a sudden drop of 10–15 points under load. Force a full recalibration: drain the phone until it powers off on its own, then charge uninterrupted to 100% without removing the cable. After one complete cycle the IC overwrites its stored curve with data from the new cell and percentage accuracy stabilises.

Frequently Asked Questions

The iPhone XR charges fine but cuts off around 20% and shuts down — is the replacement cell faulty?

The cell is almost certainly fine. The fuel gauge IC carried over the discharge curve it learned from the old, worn cell, and that stored curve no longer matches the new cell's voltage behaviour. Under modem or screen load the voltage drops below the IC's shutdown threshold before the displayed percentage reaches zero. Drain the phone until it powers off naturally, then charge to 100% in one uninterrupted session — after that full cycle the IC remaps to the new cell and the premature shutdowns stop.

Fast charging stopped working after swapping the battery on the iPhone XR — it only charges slowly now.

On the first cycle after a cell swap, the charge IC can refuse to negotiate fast-charge current until it has confirmed cell impedance is within expected range. This is a BMS protection response, not a hardware fault. Run one full standard 5W charge cycle first — this gives the charge IC baseline impedance data for the new cell. After that cycle, reconnect the fast charger and the device should accept the higher current rate normally.

The iPhone XR won't power on at all after the replacement battery sat in storage — is it dead?

Li-Polymer cells self-discharge in storage, and if the cell voltage dropped below roughly 2.5V the BMS entered lockout to prevent cell damage. The phone will not respond to a normal power-on press in this state. Connect a known-working cable and charger and leave it for 15–20 minutes without pressing anything — the charge IC applies a low trickle current to bring the cell back above the BMS re-enable threshold, typically around 3.0V. Once the cell clears that threshold the BMS unlocks, the phone shows a low-battery screen, and normal charging resumes.
