Last night I went to bed with 29% battery remaining and left it unplugged all night. With my iPhone 6 I would wake up with around 20% remaining in this situation however this morning after seven hours of sleep I woke up with only 11% remaining. Then after using the phone for about 30 seconds it completely turned off and was dead. In the settings I looked at what was draining the battery the most and 41% (which was by far the highest percentage) was allocated to Siri. I've never used Siri since I bought the phone last week and I have the "Hey Siri" function turned off. Does anyone know what this Siri drainage could be from?
