It replaces OEM part LIS1593ERPC and 1294-1249. The cell restores calling, messaging, and app use on devices where the original battery has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXperia Z5 series fit:\u003c\/strong\u003e\n    The Z5, Z5 Dual, SO-01H, and SOV32 all run the same 3.8V power rail and share an identical connector and BMS handshake profile — one cell covers all these variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Z5 unit and confirmed the BMS accepted charge from the STAMINA mode controller, held voltage under sustained LTE modem load, and did not trigger an over-current cutoff during screen-on peak draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge reset:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-charge cycle to completion. This gives the Xperia Z5's fuel gauge IC time to map the new cell's discharge curve before the charge controller applies high-current bursts against an uncalibrated baseline.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Xperia Z5 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Xperia Z5 uses a coulomb counter and a stored discharge curve to calculate state of charge. When you fit a new cell, the stored curve belongs to the old, degraded battery. The fuel gauge IC applies that worn curve to a fresh cell, so the percentage reading is inaccurate from the first boot. One complete discharge to shutdown followed by a full charge to 100% lets the IC rebuild its reference curve against the actual new cell. After that cycle, percentage jumps and erratic readings typically stop.\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 is a voltage cliff issue, not a capacity problem. Under peak modem, GPS, or screen load, the cell voltage drops sharply — faster than the fuel gauge predicts — and the BMS triggers a protective shutdown before the displayed percentage reaches zero. It happens most often in the first few cycles when the fuel gauge is still uncalibrated. Run two full discharge-charge cycles, and the IC will learn where the voltage drop-off actually occurs for this specific cell. If shutdowns continue after two full cycles, check that resting voltage at full charge reads 4.35V on a multimeter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392112099418,"sku":"BWCS-ERZ500SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392112132186,"sku":"BWCS-ERZ500SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392112164954,"sku":"BWCS-ERZ500SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERZ500SL-1.webp?v=1779143848","url":"https:\/\/batteryweb.com\/products\/sony-ericsson-xperia-z5-replacement-battery-38v-2800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
