Version .209 includes a revised power management table. The E173 typically draws ~500mA, but this build reduces idle current to (measured via USB meter). Additionally, thermal throttling now kicks in at 85°C (up from 75°C in early builds), preventing unnecessary disconnections during summer months or prolonged use in enclosures. -huawei firmware E173 11.126.85.00.209 B427-
