Last night I went to bed around 9:30 with my phone plugged in to charge. Shortly after midnight I was woken up by a loud clap of thunder. I picked my phone up to look at the radar and noticed a banner on my lock screen that said my phone would be fully charged at 3am. Sure enough, my phone was only charged to 80% even though it had been on the charger for 2.5 hours at that point! I got the weather information I needed and put my phone down to go back to sleep, but the charging issue was still bugging me. Just a few minutes later, like maybe 15 or so, I picked my phone back up and it was at 90% so it was indeed charging faster by that point. Does anyone know what could have happened with the charging?
