It fits the XT1100, XT1103, and XT1115 variants. The EZ30 cell sits beneath the rear housing and powers the Snapdragon 805 SoC, the 6-inch QHD display, and all radio modems.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXT1100, XT1103, XT1115 compatibility:\u003c\/strong\u003e\n    All three variants run the same 3.8V power rail and use the same physical cell format — 106.26 × 71.41 × 3.05mm with an identical flex connector. The BMS handshake is identical across the production run, so no firmware flag differentiates them.\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 a Nexus 6 unit. The BMS accepted the charge protocol without fault flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold during deep discharge testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable Turbo Charging for the first full discharge-to-charge cycle after installation. The coulomb counter in the Nexus 6 is calibrated to the old cell's discharge curve. Running one uninterrupted slow cycle lets the fuel gauge IC map the new cell before high-current charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Nexus 6 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nexus 6 uses a coulomb counter paired with a voltage lookup table burned to the fuel gauge IC during factory calibration. That table references the original cell's internal resistance and discharge curve. A new cell has lower impedance and a slightly different curve, so the IC misreads state of charge — often showing 100% while the cell is still at 4.1V. One full discharge to 3.4V followed by a slow charge corrects the mapping without any software intervention.\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 is a voltage cliff event, not a capacity problem. When the modem transmits or the display brightness spikes, instantaneous current draw pulls cell voltage below the BMS cutoff threshold — even though the fuel gauge still reads 25%. It happens most often on cells that have not completed a calibration cycle, because the IC does not yet know the cell's true low-voltage knee. Run one complete slow discharge to 3.4V, then charge fully. If shutdowns continue after two calibration cycles, check that screen-off battery drain is not keeping modem TX active in the background.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404175409242,"sku":"BWCS-MXT110SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404175442010,"sku":"BWCS-MXT110SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404175474778,"sku":"BWCS-MXT110SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MXT110SL-1.webp?v=1779369370","url":"https:\/\/batteryweb.com\/products\/motorola-shamu-replacement-battery-38v-3200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
