I am using Z5 Dual (E6683) with Firmware 32.2.A.0.253 and I have both SIM slots Occupied as SIM 1: Vodafone IN SIM 2: Airtel. I always keep SIM 2: Airtel Disabled using Dual SIM Setting. • I wish to know if there is Battery Consumption in any way by SIM 2 even if it's in Disabled Mode ....?? • Can I Reduce Battery Consumption by Keeping SIM 2 Slot Vaccant instead of Keeping it Occupied but Disabled...??
