It fits directly in place of the original cell and restores power to the display, processor, and wireless radios. OEM part numbers CAB31P0000C1, CAB31P0001C1, and TB-4T0058200 all cross to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT-Mobile Move compatibility:\u003c\/strong\u003e\n    The Move platform uses a single-cell 3.7V nominal Li-ion configuration with a fixed connector pinout. All three OEM part numbers reference the same physical cell and BMS handshake, so this battery covers the full Move production run without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Move platform. The BMS accepted the charge IC handshake immediately, balancing terminated cleanly, and protection circuits tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before the charge controller begins pushing higher current into an uncalibrated cell.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still running the calibration curve from the degraded original cell. The new cell's actual voltage cliff sits at a different point, so the OS reads 25% while the cell voltage has already dropped below what the modem and display draw can sustain. The phone cuts out before the reported percentage reaches zero. One full discharge-charge cycle at standard rate rewrites the coulomb counter baseline and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery on the first charge after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell starts with higher internal impedance than a broken-in cell. The charge IC compensates by running slightly longer constant-current phases, which generates more heat at the cell surface during that first cycle. This is normal and resolves after one or two full cycles as impedance drops. If the device stays warm beyond the second full charge, check that the back cover is seated flat — trapped air between the cover and cell slows heat dissipation and keeps the charge IC throttled at a warmer operating point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404341674074,"sku":"BWCS-OT990XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404341706842,"sku":"BWCS-OT990XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404341739610,"sku":"BWCS-OT990XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT990XL-1.webp?v=1779369778","url":"https:\/\/batteryweb.com\/products\/t-mobile-move-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
