It fits the same footprint at 86.90 × 63.85 × 4.18mm and connects to the same charge IC and fuel gauge circuit. Capacity matches OEM specification at 15.4Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eView 30 Pro and 5G variant fitment:\u003c\/strong\u003e\n    Both the standard and 5G variants of the Honor View 30 Pro share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell covers all listed model numbers including OXF-N29 and OXF-AL10.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a View 30 Pro unit. The BMS accepted the cell without fault codes, the charge IC stepped through trickle, CC, and CV phases correctly, and the fuel gauge held a stable state-of-charge reading across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable Huawei SuperCharge for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current fast charging pushes amperage into 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\"\u003eWhy the Honor View 30 Pro reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the View 30 Pro uses a stored discharge curve from the original cell to estimate state of charge. After a cell replacement, that stored curve no longer matches the new cell's actual voltage-to-capacity profile. The result is percentage readings that lag reality — often showing higher than actual charge until the IC recalibrates. One full discharge to auto-off followed by a complete charge to 100% resets the coulomb counter and brings the gauge back in line.\u003c\/p\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 still holds calibration data from a degraded original cell that had a steep voltage cliff near end-of-charge. The new cell has a different voltage floor, but the system cuts power based on the old threshold map. Under modem load or screen-on draw, the device hits the programmed cutoff voltage before the displayed percentage reaches zero. Run one full discharge-charge cycle with SuperCharge disabled — the IC relearns the cutoff point against the new cell and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391994200154,"sku":"BWCS-HUH310SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391994232922,"sku":"BWCS-HUH310SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391994265690,"sku":"BWCS-HUH310SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUH310SL-1.webp?v=1779142762","url":"https:\/\/batteryweb.com\/products\/huawei-honor-view-30-pro-replacement-battery-385v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
