It fits directly into the existing battery bay and connects to the same flex connector the factory cell uses. Dimensions are 84.90 × 63.05 × 3.75mm — confirm against your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVivo 5 and V0050UU fit:\u003c\/strong\u003e\n    Both model references share the same PCB layout, connector pinout, and charge IC. One cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the BLU charge IC and confirmed BMS handshake, full charge acceptance to 4.35V, and stable discharge curve under mixed screen and modem load — no premature cutoff triggered.\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 and let the phone complete one full discharge-to-charge cycle. This gives the coulomb counter a clean reference curve before high-current charging begins against an uncalibrated cell.\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 BLU Vivo 5\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a capacity problem. When the modem or display pulls a spike of current, a cell with a steep discharge curve drops voltage faster than the fuel gauge expects. The system registers that as a critical low-voltage event and shuts down even though the reported percentage looks safe. Running one full discharge cycle from 100% to automatic shutdown lets the coulomb counter map the actual voltage curve of the new cell and correct the percentage readings going forward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells that self-discharge below approximately 2.5V per cell trigger a BMS lockout as a protection measure. The phone shows nothing — no charge animation, no bootloop. Connect the phone to a wall charger, not a PC port, and leave it for 20–30 minutes without pressing any button. Most BMS circuits begin a trickle pre-charge at low voltage; once the cell climbs above the lockout threshold, the charge animation appears and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392103678042,"sku":"BWCS-GNS600SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392103710810,"sku":"BWCS-GNS600SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392103743578,"sku":"BWCS-GNS600SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNS600SL-1.webp?v=1779143797","url":"https:\/\/batteryweb.com\/products\/blu-vivo-5-replacement-battery-385v-3050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
