iPad mini first charging

Welcome to Apple Support Communities

Use the iPad and charge it when the battery percentage is 10% or below until it reaches 100%, but you can charge the battery whenever you want. If you want more information about your iPad and the battery, see > http://www.apple.com/batteries/ipad.html

Just start using it. Regarding charging...you can and should charge as often and as long as possible... deep discharges are hard on lithium batteries. Normal mobile use will result in the one charge cycle/month that Apple recommends.

This is bad advice... deep discharges are hard on lithium batteries. See my post below.
