It fits the GT-i9070, GT-i9070P, GT-I659, and closely related variants that share the EB535151VU form factor. Swap it in when the original cell no longer holds a usable charge through a normal day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT-i9070 and GT-i9070P compatibility:\u003c\/strong\u003e\n    These two variants use the same 3.8V rail, identical connector pinout, and the same BMS handshake sequence. The cell drops straight into either chassis without any wiring or adapter changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on GT-i9070 hardware. The BMS accepted the charge profile without triggering a fault, and the protection circuit cut off correctly at the low-voltage threshold — no runaway or premature lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging for the first complete discharge-charge cycle after fitting this cell. The fuel gauge IC on the GT-i9070 is calibrated to the old cell's discharge curve. One full cycle at standard current lets it remap against the new cell before higher charge rates are applied.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GT-i9070 reports the wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT-i9070 uses a coulomb-counter fuel gauge IC that builds its capacity model from accumulated charge and discharge data on the original cell. When a new cell goes in, the IC still references the old model — so the percentage shown on screen can be 10–20% off reality. This is not a fault with the replacement cell. One full discharge to shutdown followed by an uninterrupted charge to 100% forces the IC to re-anchor its zero and full points against the new cell's actual capacity. After that cycle, percentage readings settle to within a few percent of real state-of-charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the modem or display's minimum sustain threshold under load, even though the fuel gauge still reads 20–30%. The original cell's internal resistance was well-mapped; the replacement cell's curve is not yet calibrated, so the IC underestimates how fast voltage collapses under peak current draw. The fix is the same recalibration cycle: discharge fully to automatic shutdown, then charge to 100% without interruption. After that, the fuel gauge correctly predicts the voltage cliff and the OS shuts down gracefully before the cell hits 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405020823642,"sku":"BWCS-SM9070XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405020856410,"sku":"BWCS-SM9070XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405020889178,"sku":"BWCS-SM9070XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SM9070XL-1.webp?v=1779369859","url":"https:\/\/batteryweb.com\/products\/samsung-gt-i9070-replacement-battery-38v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
