I was just going to make a thread asking if this is normal; wondering if mine takes a longer time to charge compared to others.
When it's fully charged, I can see it lasting the entire 10 hours of use that Apple claims. (I've never actually let it go below 70%.)
When when I'm using it while plugged in, it will charge maybe 1% per 45-60 minutes.
The only way I can get it 100% charged is if it's not in use.
