IPhone 4 battery questions

batteryiphone

I have had an iPhone 4 with iOS5 for about 6 months.

  • Is it good to wait for the battery to be almost 0% to recharge it?
  • Is it good to recharge it to the fullest?
  • Is it bad to leave the phone plugged to the computer/wall when it is already 100% charged?
  • Is it bad never to charge the battery to its fullest?

Thanks.

This is from everythingicafe.com which is an unofficial source, but I have heard this same information about batteries many times:

So, what else can you do to increase your battery life? Charge it often. I’m serious! Apple uses Lithium Polymer batteries (not a straight lithium ion!), which perform best when you keep them “topped off”, meaning if you have a chance to charge it, then do it. I generally never let myself get below 45% unless testing due to what seems like unusual battery drainage. Apple also recommends that once a month you drain the battery down below 10% and then fully (uninterrupted) charge back to 100%. This is more for the battery meter than anything. It helps the meter get a correct reading on the battery and not display inaccurate information.

Charging at least once a month keeps the electrons moving occasionally.
