It fits the OT-5056D and all One Touch Pop 4 Plus variants sharing the same battery bay. Dimensions are 91.70 × 42.50 × 3.80mm — measure your original before ordering if you are unsure of your exact variant.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePop 4+ and Allure compatibility:\u003c\/strong\u003e\n    These models share the same battery footprint, connector pinout, and BMS communication protocol. The TLP025C1 and TLP025C2 part numbers are interchangeable across this group — Alcatel revised the part number mid-production without changing the electrical spec or physical format.\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 a Pop 4+ unit. The BMS handshake completed without error on first insertion, and the charge IC accepted a standard 5V input without entering fault mode. Cell voltage at full charge measured 4.35V — within the Li-Polymer ceiling for this platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. The fuel gauge IC on the Pop 4+ is calibrated to the discharge curve of the original cell — giving it one full cycle at low current lets the coulomb counter reset its reference 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 Pop 4+ reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pop 4+ uses a coulomb counter inside the fuel gauge IC to track remaining capacity. That counter builds its model against the original cell's discharge curve over hundreds of cycles. A new cell has a different internal resistance and a slightly different voltage-to-capacity curve, so the IC's stored model no longer maps correctly. The phone may show 100% while still on charge, or drop to 15% with no warning. One full discharge below 5% followed by a slow charge to 100% forces the IC to rewrite its reference curve against the new cell.\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 modem or display ramps current draw and the cell voltage sags below the BMS cutoff threshold — even though the reported percentage looks safe. It is not a faulty battery. The fuel gauge IC fired a shutdown percentage that was correct for the old, degraded cell, not the new one. After two or three full discharge-charge cycles, the IC recalculates the voltage cliff and the early shutdowns stop. If shutdowns continue past cycle three, check that resting cell voltage reads above 3.7V on a multimeter before inserting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392090832986,"sku":"BWCS-OTP505SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392090865754,"sku":"BWCS-OTP505SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392090898522,"sku":"BWCS-OTP505SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OTP505SL-1.webp?v=1779143707","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pop-4-replacement-battery-38v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
