Apple iPhone 11 Pro Replacement Battery 3.83V 3000mAh

Up to 20% off
New arrival
From $36.99 USD $45.99
Shipping calculated at checkout.
Fits iPhone 11 Pro models A2215 and A2160, replacing OEM battery part numbers 616-00659 and 616-00660.
Output voltage is 3.83V at 3000mAh capacity, restoring full charge capacity to the iPhone 11 Pro after degradation from charge cycles.
Connector seats into the battery slot with flex cable alignment — no locking tabs present on this internal pack design.
We tested the cell on a bench charge rig; the BMS accepted USB-PD input without negotiation errors and held voltage stable across a full discharge cycle.
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 fast charging runs on an uncalibrated cell.

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 11 Pro — 3.83V Li-Polymer Replacement Battery (616-00659)

This 3.83V, 3000mAh (11.49Wh) lithium-polymer cell replaces the internal battery in the Apple iPhone 11 Pro (A2215, A2160). It fits the models listed and matches the OEM voltage and connector spec. Install it when the original cell can no longer hold a charge through a normal day.

  • iPhone 11 Pro fit (A2215, A2160): These model numbers share the same battery bay dimensions, flex connector pin-out, and BMS handshake protocol. A cell built to 3.83V nominal works with the charge IC on all three variants without triggering a mismatch flag.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an iPhone 11 Pro board, monitoring BMS communication, cutoff voltage at load, and fuel gauge IC response. The cell held rated capacity and cleared all hardware health checks in iOS.
  • First-cycle fast charge protocol: 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's discharge curve before high-current USB-PD pushes current into an uncalibrated cell.

Sudden shutdown at 20–30% after a cell swap

The iPhone 11 Pro's fuel gauge IC tracks a discharge curve learned from the previous cell. After a swap, that stored curve no longer matches the new cell's actual voltage-versus-capacity profile. Under high load — cellular modem, GPS, or screen at full brightness — the cell voltage drops faster than the gauge expects, and the BMS trips a low-voltage cutoff before the percentage reading catches up. Run two full discharge-to-charge cycles without fast charging to let the coulomb counter relearn the curve. After calibration, shutdowns at elevated percentage readings typically stop.

iOS reporting battery health below 100% immediately after installation

iOS calculates battery health by comparing the cell's current full-charge capacity against a baseline written to the fuel gauge IC during the original factory calibration. A new aftermarket cell starts with no matching baseline, so iOS reads a mismatch and displays a reduced health figure or the "Unable to verify battery" message. This is a gauge calibration state, not a cell defect. Complete one full charge to 100% followed by a full discharge to automatic shutoff, then charge back to 100% — the fuel gauge IC will write a new baseline and the health reading will update accordingly.

Frequently Asked Questions

My iPhone 11 Pro shuts off at around 25% battery — does the replacement cell have a fault?

The cell itself is not faulty. The fuel gauge IC on the 11 Pro is still using the discharge curve it learned from your old degraded cell, so when voltage drops under modem or screen load, it trips a BMS cutoff before the percentage reading reflects the actual state of charge. Run two full discharge-and-charge cycles without enabling fast charging. After the coulomb counter recalibrates against the new cell's curve, the shutdowns at 20–30% should stop.

Fast charging stopped working the first time I plugged in after swapping the battery — is the new cell rejecting USB-PD?

On the first cycle after a cell swap, the charge IC can fail to complete the USB-PD handshake because the BMS presents a higher impedance on a fresh, uncalibrated cell than the controller expects. This is temporary. Use a standard 5W charger for the first full charge, let the cell discharge to automatic shutoff, then charge again — after that initial cycle the USB-PD negotiation completes normally and fast charging re-engages.

The phone felt warm near the battery for the first hour of charging after I installed the replacement — is something wrong?

This is normal on a new high-impedance lithium-polymer cell during the first charge. The charge IC has not yet profiled the cell's internal resistance, so it starts with a conservative current ramp that generates slightly more heat than steady-state charging on a conditioned cell. Surface temperature should stay below 38°C — if it does, no action is needed. If the case feels hot to the touch or charging stops early, check that the battery flex connector is fully seated and the locking clip is closed before charging again.
