Battery life has been fine so far. But just today it's started doing something odd. I had it on the (wireless) charger and it showed 93% charged, but didn't change after like 10 minutes. I thought that was odd. Plugged it in and it continued to say 93%. Powered down and back on - 98%. Put it on the charger again: 97% and has said so for the last 10 minutes again. If it keeps up like this it's going to need to go back. I had enough games with my iPhone 6 battery doing it's magic freefalls from 40% to 1%, staying at 1% for an hour, plugging in and jumping immediately to 65%.
