T1560840681374, Jul 17, 2019 : results after turning GPS off, I have even used flashlight for few minutes due to power outage. Anyways, pretty pleased with the result. Got Screen on time of more than 8 hours..... But still stand by time is where battery drain is the most, I think it might be because of my dual sim combination (maybe) that is Jio and Idea. I will be moving to Canada in about 15 days and will post results with single sim.
