It uses the same OEM part number C735804180T and fits the same battery bay without modification. If your phone no longer holds a charge or shuts down unexpectedly, this cell restores normal operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLife Play \/ Life Play X compatibility:\u003c\/strong\u003e\n    Both the Life Play and Life Play X use the same 3.7V battery bay, connector pitch, and BMS handshake protocol. One cell covers both models. No adapter or modification required.\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 Life Play platform. The BMS accepted the new cell without triggering lockout, and the charge IC ramped current correctly through CC and CV phases.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use after installation, run one complete discharge-charge cycle with fast charging disabled. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on 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 Life Play after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Life Play uses a coulomb counter that was calibrated to the discharge curve of the original cell. A new cell with a slightly different internal resistance profile causes the fuel gauge to misread remaining voltage under load. When the modem or screen pulls a short burst of current, the actual cell voltage drops below the shutdown threshold even though the reported percentage looks healthy. One full discharge-charge cycle with the screen on and mobile data active forces the IC to relearn the curve. After that cycle, shutdowns at false percentages stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the cell voltage dropped below approximately 2.5V before installation, the BMS enters a protective lockout state and blocks normal boot. The phone will show nothing on screen even with a charger connected. Connect the phone to a wall adapter — not a USB port — and leave it for 20 to 30 minutes without pressing the power button. Once the cell recovers above the BMS recovery threshold, the charge IC will resume and the phone will respond normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404164300890,"sku":"BWCS-BLX100SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404164333658,"sku":"BWCS-BLX100SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404164366426,"sku":"BWCS-BLX100SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLX100SL-1.webp?v=1779369251","url":"https:\/\/batteryweb.com\/products\/blu-life-play-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
