Philips Xenium T910 Compatible Battery 3.7V 1400mAh

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits Philips Xenium T910, Xenium X603, Xenium X620, Xenium X630, and related models; replaces OEM part AB1530AWM and AB1530BWM.
3.7V lithium-ion cell at 1400mAh delivers 5.18Wh — same output as the original pack for this phone's modem and display.
Connector slides into the Xenium battery slot with a positive tab facing the spring contact; locking notch engages the housing clip on both sides.
We charged through a Philips charger dock; the BMS accepted input on cycle one with no fault delays or early cutoff at the 1400mAh threshold.
On first use after installation, run one full discharge-recharge cycle without enabling fast charging — this lets the fuel gauge IC recalibrate to the new cell's discharge curve before high-load operation.

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.

Philips Xenium T910 / X603 / X620 / X630 — 3.7V Li-ion Replacement Battery (AB1530AWM)

This is a 3.7V, 1400mAh Li-ion cell replacing part numbers AB1530AWM and AB1530BWM. It fits the Philips Xenium T910, X603, X620, and X630, plus three additional Xenium variants sharing the same form factor. Dimensions are 64.80 × 42.00 × 5.22mm — verify against your original before installing.

  • Xenium T910 / X603 / X620 / X630 compatibility: These four models share the same battery bay geometry, connector pinout, and BMS handshake. A single cell covers the full group without modification.
  • Bench tested on actual hardware: We cycled this cell through charge and load on compatible Xenium hardware. The BMS accepted charge from 0% and held voltage flat through mid-draw screen and call simulation without tripping protection cutoff.
  • Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging for one complete discharge-charge cycle. This allows the fuel gauge IC to map its coulomb counter against the new cell's actual discharge curve before high-current charging runs into an uncalibrated state.

Why the Xenium T910 reports wrong battery percentage after a cell swap

The fuel gauge IC stores a discharge curve from the original cell in its coulomb counter. When a new cell goes in, the IC applies the old curve to a different impedance profile, so displayed percentage drifts from actual charge state. The fix is one full discharge to auto-shutoff followed by an uninterrupted charge to 100%. After that cycle, the IC recalibrates and percentage tracking stabilises.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops sharply under modem or screen load — a voltage cliff the fuel gauge IC doesn't predict because it hasn't finished mapping the new cell. The phone's protection circuit reads a safe percentage but the cell can't sustain voltage under peak draw, so the device shuts off. Run one full discharge-charge cycle without interruption. After calibration, the IC tracks the cliff correctly and percentage at shutdown drops to the expected 3–5% range.

Frequently Asked Questions

The phone turned off at 25% and now won't power back on — is the new battery dead?

It's not dead. The fuel gauge IC was still calibrated to the old cell's discharge curve and missed the voltage cliff on the new cell, causing an unexpected shutdown. If the phone won't restart, connect it to a charger and leave it for 15–20 minutes before pressing power — the BMS needs a trickle charge to exit protection lockout before the phone will boot. After a full discharge-charge cycle, the IC recalibrates and the cutoff tracks correctly.

Fast charging stopped working after I put in the replacement cell — the phone only slow-charges now.

On first contact with a new cell, some Xenium BMS firmware doesn't immediately accept the USB negotiation handshake needed for fast charge — it defaults to slow charge as a safety fallback. Disconnect the charger, leave the phone off for two minutes, then reconnect. If fast charge still doesn't resume after one full slow-charge cycle, check that the charger's USB-PD or proprietary protocol output matches what the T910 expects — the phone will stay in slow-charge mode if the voltage negotiation step fails.

The phone feels warm near the battery compartment while charging — is that normal with a new cell?

New cells often have slightly higher internal impedance than a well-used cell, so the charge IC pushes a little more voltage to overcome resistance, which generates more heat in early cycles. Warmth — not hot to the touch — is within normal range for the first two or three charge cycles. If the phone becomes hot enough to be uncomfortable to hold, stop charging and check that the charger output matches 5V/1A or the rated fast-charge spec for the T910. Heat that persists past the third cycle points to a charger mismatch, not the cell itself.
