As with every other person here who has posted regarding this issue, my phone is doing the exact same thing. I can't even get through the train ride home any longer. Recently, I had to shut off my phone and hope it rebooted so once I arrived at the train station, I would have enough battery to call an Uber. Luckily, it did but then drained to zero on the car ride home. I'm beyond frustrated by reading 37 pages of folks posting the same issue and having the EXACT same response coming every time.
