About this replacement
Samsung GT-i9070 Galaxy S Advance — 3.7V Li-ion Replacement Battery (EB535151VU)
This is a 3.7V, 3200mAh Li-ion cell for the Samsung GT-i9070 and GT-i9070P, sold under OEM part number EB535151VU. It fits directly into the Galaxy S Advance and restores power to a device that's draining fast, swelling, or refusing to hold a charge. Capacity listed is from product data — 11.84Wh.
- GT-i9070 and GT-i9070P compatibility: Both variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. This cell matches the 51.00 × 50.50 × 10.20mm footprint and communicates with the Galaxy S Advance charge IC without triggering an unrecognised-battery warning.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a GT-i9070 unit. The BMS accepted the cell without error flags, the charge IC stepped through trickle, bulk, and top-off phases correctly, and the fuel gauge IC tracked state-of-charge without erratic jumps after the first full cycle.
- Fuel gauge recalibration on first use: Disable any fast-charge accessory for the first full discharge-to-charge cycle after installing this cell. The GT-i9070 fuel gauge IC calibrates against the cell's discharge curve on that first pass — skipping it with high current input leaves the coulomb counter offset against an uncalibrated baseline.
Sudden shutdown at 20–30% on the GT-i9070 after a cell swap
A new cell has a slightly different voltage-to-capacity curve than the aged original it replaces. The GT-i9070's fuel gauge IC still holds the old curve in memory, so it reads 25% state-of-charge while the actual cell voltage has already dropped near the BMS cutoff threshold. Under modem or display load, the voltage sags past that cutoff and the phone shuts down — even though the percentage display looked fine. One complete discharge cycle from 100% to automatic shutdown, followed by a full charge, forces the coulomb counter to re-learn the new cell's curve. After that cycle, reported percentage and actual cell voltage align.
Phone stays on the Samsung logo screen after battery sits discharged in storage
Li-ion cells self-discharge at roughly 1–2% per month in storage. A GT-i9070 left unused for six months or more can drain the cell below 2.5V per cell, which triggers BMS lockout — a protective state that blocks normal charge current to prevent plating. The phone will loop on the boot logo or show no sign of life even when plugged in. Connect the device to a wall adapter — not a PC USB port — and leave it for 20–30 minutes without pressing any buttons. The charge IC delivers trickle current at around 100mA to recover the cell voltage above the BMS re-enable threshold of approximately 3.0V, after which normal charging resumes.
