It fits the original battery bay and connects to the same charge and protection circuit the phone was built around. Capacity is sourced from the product specification — 1100mAh, 4.07Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSTARADDICT Android Edition fit:\u003c\/strong\u003e\n    The STARADDICT Android Edition uses a fixed 3.7V single-cell architecture with a direct connector to the charge IC. This cell matches that voltage rail and connector pinout, keeping the fuel gauge IC in the loop for accurate state-of-charge reporting.\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 bench. The BMS held the charge cutoff at the correct upper voltage, and the low-voltage cutoff triggered cleanly before cell damage could occur.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge recalibration:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging for one full discharge-charge cycle. The fuel gauge IC holds calibration data from the old cell's discharge curve. Running one slow cycle against the new cell lets the IC rebuild that curve 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\"\u003eSudden shutdown at 20–30% on the STARADDICT after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. When the modem transmits or the screen peaks in brightness, current draw spikes sharply. A new cell with an uncalibrated fuel gauge IC can report 25% remaining while the actual cell voltage has already dropped below the BMS cutoff threshold under that load. The phone shuts down to protect the cell, even though the percentage on screen looked safe. One full slow discharge-charge cycle lets the coulomb counter recalibrate against the new cell's real discharge curve, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the STARADDICT learns the discharge curve of the cell it was calibrated against. Swap the cell, and the IC is reading a new cell's voltage response against old reference data — the mismatch shows up as percentage jumps of 5–15% in either direction. This is not a fault with the replacement cell. Run the phone down to auto-shutdown from a full charge, then charge it uninterrupted to 100% without fast charging enabled. After that single cycle the IC resets its coulomb counter baseline and percentage reporting stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405074038874,"sku":"BWCS-ZTV900SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405074071642,"sku":"BWCS-ZTV900SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405074104410,"sku":"BWCS-ZTV900SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTV900SL-1.webp?v=1779369935","url":"https:\/\/batteryweb.com\/products\/sfr-staraddict-android-edition-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
