It fits the original battery bay without modification. Capacity is rated at 16.94Wh and matches the factory specification for this model.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV1913 and V17 Neo compatibility:\u003c\/strong\u003e\n    Both model numbers share the same PCB layout, connector pinout, and BMS handshake protocol — the V1913 is the internal hardware designation for the V17 Neo retail unit. One cell fits both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge-discharge cycles on the V17 Neo with this cell installed. The BMS accepted the cell without fault flags, charge current ramped correctly through CC-CV stages, and cutoff triggered cleanly at 4.35V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes into an uncalibrated coulomb counter — it prevents erratic percentage readings from the first day.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old cell's internal resistance profile. The new cell hits a voltage cliff under modem or display load that the IC didn't anticipate, so the phone shuts down before the reported percentage reaches zero. It is not a faulty cell — it is a calibration mismatch. Run two full discharge-charge cycles without interruption and the coulomb counter will remap to the new cell's actual discharge curve. After that, shutdowns below 20% should stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD or Vivo FlashCharge not activating after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell swap, the charge IC on the V17 Neo sometimes defaults to standard 5V\/1A charging on the first cycle while it negotiates with the new BMS. This is normal behaviour — the controller is confirming cell acceptance before allowing high-current delivery. Plug in, let a full charge complete at standard rate, then unplug and replug. FlashCharge handshake typically re-establishes on the second connection once the BMS has logged one complete cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391996428378,"sku":"BWCS-BYV170SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391996461146,"sku":"BWCS-BYV170SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391996493914,"sku":"BWCS-BYV170SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BYV170SL-1.webp?v=1779142855","url":"https:\/\/batteryweb.com\/products\/vivo-v1913-replacement-battery-385v-4400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
