Hi everyone, I was on a call for almost 3 hours, so when I checked my battery life after I hung up, I was startled to see the battery drained over 40% just from a wifi phone call. The phone was on 87% when I made the call and down to 45% once I was done. I have the 6s set to low power and no other apps were open or running in the background. 9.3.1 is installed. And Blue Tooth etc. are off. I would expect that kind of rapid battery drain if I didn't have low power on, but just wondering if that is normal. I've had the 6s since December.
