Any other figures regarding recharging ?
I can't give you specifics, but I can say it isn't very quick with the official mains charger. It is a 5100mAh battery after all, I'm not complaining, it's just my iPad 2 is noticably quicker in this regard.
what would be an estimate ?
Not a clue at this point I'm afraid. It's never gone below 30% from my usage and I've nearly always just charged it overnight so far. If I do charge it during the day in the next couple of days I'll make a note and post the results.
I once charged from 15% to 85%. I observed at several points along the way, and it was consistently charging about 1% every two minutes.
@Yes, I let mine go to 5%, charged it to full in 4 hrs. Left it on all night, it lasted till 5pm, charged full by 8:30. So 3.5 hours to charge from 0-full. We'll see if it makes it through the night off charger.
