Hi Does anyone keep the personal hotspot permanently on? I want to turn it on always, so that my Android tablet can tether to my iphone 5 automatically. However, it seems that even without any connection, just turning on the hotspot feature the battery will die very quickly, eg 1% per 3-5 mins. Why? In the past I was using a galaxy nexus android phone, which does not draw any extra battery even with tethering turn on with no active connection.
