I bought two iPad Mini 4 devices; one on release day, one a few weeks later (at the time, I was running a large development team with a serious iPad shortage). We had many many issues with these devices, but that's another story. Recently both iPad minis have had absolutely terrible battery life. Even just idling, case-closed, barely any apps installed to drain the power, bluetooth off etc, these things are struggling to last 24 hours. It's not just one; both are doing horribly. They are both running the latest iOS and this problem has kicked up in the last few weeks, so I am wondering if it's a hardware or software issue? I'm very skeptical about saying it's just "a bad battery" as both devices are having the exact same issue. Anyone else finding the battery life apalling with a bit of age? I'd like to hear from people that are and are not, along with which iOS you are running and hold long ago you got your iPad Mini 4. I'm not just venting and complaining, I would like to understand the reasoning behind it.
