What changed for policy compliance
Removed "battery saver" and "battery optimizer" — these were the flagged impossible claims

Removed outcome guarantees ("fixes that for good," "years longer," "never run out") — replaced with what the app measurably does

"Battery health score" → "estimated battery health overview," since the app estimates from cycles, it doesn't measure hardware
