It restores power to a phone that no longer holds charge or fails to turn on. Capacity is 8.36Wh — matching the stock specification for this model.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHighscreen Tasty fit:\u003c\/strong\u003e\n    The Tasty uses a compact Li-Polymer pouch cell on a 3.8V nominal rail. This replacement matches that rail, connector footprint, and BMS handshake requirements so the charge IC recognises the cell and begins charging normally.\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 cutoff at the correct thresholds — no premature termination, no overcharge trip. Coulomb counter initialisation completed within the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging for the first complete discharge-charge cycle. The fuel gauge IC on the Tasty is calibrated to the old cell's discharge curve. Running one slow cycle lets it recalibrate against the new cell 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 Highscreen Tasty after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a different internal resistance profile than the aged original. When the modem fires a data burst or the screen ramps brightness, current draw spikes. If the fuel gauge IC still expects the old cell's voltage sag curve, it misreads state-of-charge and allows the phone to run into an actual low-voltage cutoff — which the OS reports as a sudden shutdown at what appears to be 20–30%. One full slow discharge-charge cycle resets the coulomb counter and maps the new cell correctly. After that cycle, shutdowns at false percentages stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHighscreen Tasty not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge during storage. If the cell voltage drops below approximately 2.5V per cell, the BMS enters a lockout state to prevent damage and the phone will not respond to the power button. Connect the phone to a charger with a known-good cable and leave it for 15–20 minutes without pressing anything. The charge IC will trickle current into the cell until voltage climbs above the BMS recovery threshold — typically 3.0V — at which point the BMS unlocks and normal charging resumes. If the phone still shows no response after 30 minutes, try a different USB power adapter rated at 5V 1A or higher.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392042893402,"sku":"BWCS-HAT100SL-1","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43392042926170,"sku":"BWCS-HAT100SL-2","price":30.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43392042958938,"sku":"BWCS-HAT100SL-3","price":33.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAT100SL-1.webp?v=1779143125","url":"https:\/\/batteryweb.com\/products\/highscreen-tasty-replacement-battery-38v-2200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
