It fits directly in place of the original EB-L1D7IVZ cell and restores power to the display, modem, and processor. Swap it when the original cell can no longer hold a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-I515 fit:\u003c\/strong\u003e\n    The Droid Charge uses a dedicated battery bay with a specific connector pitch and contact orientation. This cell matches those physical and electrical specs — the BMS handshake between the battery and the phone's charge IC will complete normally on first insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the SCH-I515 platform. The BMS communicated correctly with the phone's fuel gauge IC, and the charge IC accepted the cell without faults at both standard and high-current charge rates.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this battery, disable fast charging for the first full discharge-charge cycle. The fuel gauge IC on the Droid Charge calibrates against the cell's discharge curve — running one slow cycle first lets it map the new cell accurately before fast-charge current is 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 Droid Charge reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SCH-I515 uses a coulomb counter in its fuel gauge IC to track charge state. That counter was calibrated against the original cell's internal resistance and discharge curve. A new cell has different impedance characteristics, so the stored curve no longer matches actual voltage behaviour. The IC reads a percentage based on stale data until it completes one full discharge-charge cycle and rewrites its reference table. Run the phone from 100% down to automatic shutdown once, then charge uninterrupted to 100% — the gauge will track correctly after that.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the modem or display pulls a current spike and the cell voltage drops sharply below the BMS cutoff threshold — even though the reported percentage looks safe. On the SCH-I515, LTE modem bursts and screen-on events together can pull enough current to cause a momentary voltage sag below 3.2V on an uncalibrated cell. The BMS interprets that sag as an empty cell and cuts power. Run one full calibration cycle as described above — once the fuel gauge IC maps the new cell's voltage cliff accurately, the reported percentage and the actual cutoff point will align.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405041303642,"sku":"BWCS-SMI515XL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405041336410,"sku":"BWCS-SMI515XL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405041369178,"sku":"BWCS-SMI515XL-3","price":27.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/samsung-sch-i515-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
