Philips E570 Replacement Battery AB3160AWMT 3.7V 3000mAh

Philips Xenium E570 / E571 — 3.7V Li-ion Replacement Battery (AB3160AWMT)

This is a 3.7V, 3000mAh Li-ion battery for the Philips E570, E571, Xenium E570, and Xenium E571 phones. It replaces OEM part AB3160AWMT when the original cell degrades and can no longer hold a usable charge. Capacity listed is 3000mAh (11.1Wh) — taken from the product data, not estimated.

• Xenium E570 and E571 fitment: Both models use the same battery bay dimensions, connector pinout, and BMS handshake protocol. The AB3160AWMT part number covers both variants — the cells share the same voltage rail and charge IC interface.
• Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle on compatible hardware. The BMS accepted the charge IC handshake without error flags, and voltage held stable across the discharge curve without unexpected cutoff.
• Fuel gauge recalibration on first use: After fitting this battery, disable fast charging and complete one full discharge-charge cycle before resuming normal use. The phone's fuel gauge IC is calibrated to the old cell's discharge curve — one full cycle lets it map the new cell's actual capacity and prevents early percentage jumps or false low-battery alerts.

Sudden shutdown at 20–30% on the Xenium E570

This is a voltage cliff failure — not a capacity problem. When the modem fires during a call or the screen peaks in brightness, instantaneous current draw spikes. A degraded or freshly installed uncalibrated cell can't sustain voltage under that load, and the phone shuts down even though the fuel gauge still shows charge remaining. The fix is a full recalibration cycle: charge to 100%, drain to automatic shutoff, then recharge fully without interruption. After that cycle the fuel gauge IC maps the new cell's actual voltage-to-capacity curve, and the false cutoff stops.

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

Li-ion cells that discharge below roughly 2.5V per cell trigger a BMS lockout — the protection circuit opens to prevent damage, and a normal charger handshake gets no response. The phone appears completely dead. Connect it to a low-current USB source (a wall adapter, not a fast charger) and leave it for 20–30 minutes before pressing the power button. The BMS needs a trickle input to cross back above the lockout threshold before it will allow a full charge cycle to begin.
