Hey guys, I have a question regarding the battery on my iPad Pro. I woke up this morning with 86% battery and left it laying there without doing anything with it. When I picked it up in the evening (about 10-11 hours later), my battery was down to 82%. Is a 5% drain over half a day really normal? I already did a DFU restore last week since I thought my battery drain is too high. I have background refresh disabled. The only thing connected to the ipad is my apple pencil. I notice that each time I turn the display on, the bluetooth icon in the corner is "blinking" or "flickerign" for a second or so before it is all white. Is that a problem? Thanks!
