Vodafone Smart Ultra 6 1ICP4/63/70 Replacement Battery 3.8V 3000mAh

Vodafone Smart Ultra 6 V995 / VF-V995 — 3.8V Li-Polymer Replacement Battery (1ICP4/63/70 1S1P)

This is a 3.8V, 3000mAh (11.4Wh) Li-Polymer replacement battery for the Vodafone Smart Ultra 6, including variants sold as V995, V995N, and VF-V995. It uses OEM part number 1ICP4/63/70 1S1P and matches the original cell's physical dimensions at 85.00 × 62.65 × 3.60mm. Swap it in when the original cell no longer holds a charge or triggers unexpected shutdowns.

• Smart Ultra 6 variant coverage: The V995, V995N, and VF-V995 all share the same battery bay geometry, connector pinout, and BMS handshake protocol — one cell fits every variant in this lineup.
• Bench tested on actual hardware: We ran full charge and discharge cycles on this cell in a Smart Ultra 6 chassis. The BMS accepted the new cell without fault flags, and the protection circuit tripped correctly at both high-current draw peaks and at low-voltage cutoff.
• Fuel gauge recalibration after install: On first use after fitting this cell, disable fast charging and run one complete discharge down to auto-shutdown, then charge to 100% uninterrupted. This gives the fuel gauge IC a clean reference cycle against the new cell's discharge curve before high-current charging begins against an uncalibrated coulomb counter.

Sudden shutdown at 20–30% on the Smart Ultra 6 after a cell swap

This is a voltage cliff issue, not a cell defect. The Smart Ultra 6's modem and display together pull enough current that if the fuel gauge IC is still calibrated to the old degraded cell's discharge curve, it misreads the new cell's state of charge. The phone thinks it has 25% left, but the fuel gauge hasn't mapped the new cell's actual voltage-to-capacity relationship yet. One full discharge-charge cycle with fast charging off forces the coulomb counter to rebuild the reference table — shutdowns at partial charge typically stop after that cycle.

Phone warm near the battery compartment on first charge after replacement

A fresh Li-Polymer cell has higher internal impedance than a broken-in one. During the first few charge cycles, the charge IC works against that elevated impedance, and the excess energy dissipates as heat near the battery. This is normal and reduces as the cell completes its first three to five cycles. If the warmth persists past five full cycles or the phone becomes hot to the touch, check that the replacement cell is seated flat with no lift at the corners — poor contact raises impedance further. Surface temperature should settle below 38°C during normal charging by cycle three.
