It fits directly into the G2 Touch battery bay and connects via the original contact terminals. Use the capacity figure from this listing — 2200mAh — as the reference spec for this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG2 Touch platform fit:\u003c\/strong\u003e\n    The G2 Touch uses a standard removable Li-ion cell with a three-contact layout. This battery matches that contact arrangement, voltage rail, and physical footprint — 65.02 x 40.01 x 8.90mm — so it seats without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on a G2 Touch-class test rig. The BMS held charge termination correctly at 4.2V and did not trigger premature cutoff under simulated screen and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging if your charger supports it and run one full discharge-charge cycle before normal use. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on 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\"\u003eWhy the G2 Touch reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe G2 Touch uses a fuel gauge IC that builds its charge model from past discharge cycles on the original cell. When you fit a new cell, the IC's stored curve no longer matches the new cell's actual voltage-to-capacity relationship. The phone reads voltage and maps it against the old model, producing percentage figures that are off by 10–20%. One complete discharge to auto-off followed by a full charge to 4.2V resets that mapping 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 draws a short burst of current and the cell voltage drops sharply below the BMS cutoff threshold — even though the fuel gauge still shows charge remaining. It is a voltage-sag issue, not a capacity issue. A fresh cell can hit this cliff if the fuel gauge IC is still calibrated to the degraded curve of the old battery. Run two full discharge-charge cycles and check that resting cell voltage reads above 3.7V before the third cycle begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405139705946,"sku":"BWCS-HDE190HL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405139738714,"sku":"BWCS-HDE190HL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405139771482,"sku":"BWCS-HDE190HL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDE190HL-1.webp?v=1779370263","url":"https:\/\/batteryweb.com\/products\/t-mobile-g2-touch-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
