A friend says you should always run the battery all the way down before recharging the iPad or iPhone. This increases the life of the battery. Is this true? I remember years ago that this was true but thought the new batteries don't need that.

The discharge to calibrate routine is a modern urban myth with all Apple mobiles. It used to be used ONLY on old and ancient Macs. Doing that WILL NOT result in any more accurate level prediction and WILL result in rapid battery wear, degradation and shortened lifetime.
Charge when needed, try to avoid discharging below a 20-30% level if possible. Yes, the batteries will inevitably die and yes, it will be a PITA when it happens. Running them down to the ground every time will only ensure that happens so much sooner.
The somebody needs to let Apple know that they are posting bad information.

Use Your iPad Regularly
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
No it is unnecessary to run down the battery before charging it. Charge it when it needs to be charged or when it is convenient for you. Do not make a practice of running the battery down unless you are doing the once a month charge cycle, (let the iPad battery run down and shut off on it's own and then recharge to 100 %) as Apple recommends in order to calibrate the battery gauge.
I have not calibrated the battery gauge in over a year and my iPad battery is fine and dandy.
Should I run down the battery in my iPad before charging it?
