I don't know if anybody else has experienced this, but the other day I had 100% on my iPad Pro when I left for work at 6:30 am. Upon returning at 3:30 pm, I picked up my iPad Pro and noticed that it was slightly warm (bad sign). I opened it and had 7% power! I rebooted and charged it to 100% and then disconnected power. By the next morning, it was down to 60%. It had to be either a rogue program or the new update. I remember installing Facebook Messenger the day of the power drain, so I uninstalled it this morning. After recharging to 100%, I have now had it on standby for 2.5 hours and it is still at 100%. Anybody else having issues with Messenger?
