It uses OEM part number C645005185L and fits the original battery slot without modification. Capacity is rated at 5.74Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStudio Mini, Studio Mini LTE, and X100Q compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, connector pinout, and 3.7V nominal voltage rail. The BMS handshake on each device accepts the same cell profile, so one SKU covers all three.\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 Mini platform. The BMS accepted the cell on first connection, charge termination triggered correctly at full capacity, and the protection circuit tripped as expected under short-circuit conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use, disable fast charging if your carrier app or handset supports it, then run one complete discharge-to-charge cycle at standard current. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before higher charge rates are applied to 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 Studio Mini after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a different internal impedance profile than the worn cell the fuel gauge IC was calibrated to. Under modem or screen load, voltage sags faster than the gauge predicts, and the BMS cuts power before the displayed percentage reaches zero. The phone reads 25% but the cell voltage has already dropped below the BMS cutoff threshold. One full discharge-charge cycle resets the coulomb counter and aligns the percentage readout with the new cell's actual voltage curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone stays at 1% or won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this battery shipped or was stored for several weeks, cell voltage may have dropped below the BMS lockout threshold — typically 2.5V per cell. The BMS enters a protective sleep state and the phone shows no charge indicator or stays off entirely. Connect the phone to a wall charger, not a PC USB port, and leave it for 15–20 minutes without pressing the power button — wall adapters supply enough current to wake the BMS from lockout. Once the charge indicator appears, the cell is recovering and normal charging will resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404129337434,"sku":"BWCS-BLX110SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404129370202,"sku":"BWCS-BLX110SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404129402970,"sku":"BWCS-BLX110SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLX110SL-1.webp?v=1779369037","url":"https:\/\/batteryweb.com\/products\/blu-studio-mini-replacement-battery-37v-1550mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
