Background: For awhile now my GF has told me her iPhone 5 battery has been wacky lately. When charged to say 97% and like 30 mins later or so it would show 67%. Sometimes at say 56% and plugging it in to charge it shows 30%. At Apple Genius Appointment: Told the "Genius" my problem. He first took out sim card and saw the sensor was triggered. I told him that couldn't be this phone was never dropped in water. He said well it was exposed to water. I told him to take it in the back and check all the other sensors and they were OK. But since this sensor was triggered I could not get my phone serviced under warranty. I was pretty pissed...The only time this phone would have gotten exposed to water is due to humidity. Sometimes the phone would be taken in the bathroom while taking showers. I just don't understand this stupid policy. If I was living in a humid environment like Florida, and somehow the stupid sensor got triggered from the humidity, my warranty on my phone is now voided?
