It fits the S010Q, Studio G HD LTE, and S0250UU using OEM part number C755843220L. Install it when the original cell no longer holds charge or the phone shuts down unexpectedly before reaching 0%.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStudio G2 Plus and S010Q compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and charge IC voltage rails — 70.60 x 57.86 x 4.06mm. A single cell covers all four fit models without modification.\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 the Studio G2 Plus platform. The BMS accepted handshake on the first cycle and the charge IC reached 4.2V cutoff without interruption.\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 run one full discharge-to-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Studio G2 Plus reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the Studio G2 Plus stores a learned discharge curve from the previous cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry, so the IC reports inaccurate percentages. The phone may show 40% and then jump to 15% without warning. One full discharge-charge cycle without interruption forces the IC to relearn the new cell's voltage-to-capacity relationship and restore accurate readings.\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 modem radio or screen load pulls current fast enough to cause a brief voltage sag below the BMS cutoff threshold — even though the displayed percentage looks safe. The old fuel gauge calibration makes this worse because the IC underestimates how close the cell is to its low-voltage floor. The fix is the same recalibration cycle: drain the phone to auto-shutdown, charge uninterrupted to 100%, and repeat once. After two full cycles, the coulomb counter tracks the new cell accurately and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392036339802,"sku":"BWCS-BLG200SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392036372570,"sku":"BWCS-BLG200SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392036405338,"sku":"BWCS-BLG200SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLG200SL-1.webp?v=1779143085","url":"https:\/\/batteryweb.com\/products\/blu-studio-g2-plus-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
