It replaces OEM part numbers EB-L1G6LLA and EB-L1G6LLAGSTA. The battery slots into the same rear-cover bay and connects via the original multi-pin contact strip.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSPH-L710 and Galaxy S3 compatibility:\u003c\/strong\u003e\n    The Sprint SPH-L710, standard Galaxy S3, and Galaxy SIII share the same battery bay dimensions and three-pin contact layout. The BMS handshake protocol is identical across these variants, so the fuel gauge IC reads cell state correctly without firmware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an SPH-L710 and monitored the BMS charge termination. The protection circuit cut off cleanly at full charge and held stable contact voltage across three full discharge cycles without tripping the low-voltage lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this battery, disable fast charging and run one complete discharge-charge cycle before normal use. The fuel gauge IC on the Galaxy S3 calibrates its coulomb counter against the new cell's discharge curve on that first cycle — skipping it causes the percentage to read inaccurately for the first several days.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SPH-L710 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy S3 uses a fuel gauge IC that tracks charge state by counting coulombs against a stored discharge curve from the previous cell. When a new cell goes in, that stored curve no longer matches the actual chemistry. The IC reports percentage based on stale data until it completes a full discharge-charge cycle and recalculates. Until recalibration is complete, the percentage display can read 10–20% higher or lower than the real state of charge. One full cycle from 100% down to automatic shutdown and back to 100% resets the curve.\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 cell voltage drops sharply under combined modem and display load — a voltage cliff the fuel gauge did not predict. The SPH-L710's LTE radio draws a short high-current burst during handoff, and if the cell cannot sustain voltage above the BMS cutoff threshold during that burst, the phone shuts off even though the reported percentage looks safe. The fix is to run two or three full cycles so the fuel gauge IC maps the new cell's actual voltage sag at load. After calibration, the low-battery warning fires at the correct percentage before the cliff is reached.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405020135514,"sku":"BWCS-SMI930SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405020168282,"sku":"BWCS-SMI930SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405020201050,"sku":"BWCS-SMI930SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI930SL-1.webp?v=1779369859","url":"https:\/\/batteryweb.com\/products\/sprint-galaxy-s3-replacement-battery-37v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
