If it is within warranty, have them replace the unit.
Are you using a wall charger or a trickle-charger such as the USB Cable? The wall charger is the only way to truly charge it to full.
If you are using a USB charger or other trickle charger, after the device says it is fully charged remove it from the charger for about 2 minutes and then reconnect it. It will then charge (most of) the rest of the way.
If you don't do this, the problems gets worse and worse. After 1 day, the trickle charger may get you up to a 90% charge. After two days, 80%, etc. After a week you'll only be holding half a charge, even though the device is reporting a full charge while on the charger.
Another tip I have found is to perform a soft-reset after removing it from the charger, particularly if it has been plugged in for a long time at full charge (more than an hour or so). It seems like the device doesn't always detect that it has been unplugged and tries to **** down juice as if it were still plugged in. If you have noticed that your device gets pretty hot when the battery drains quickly, this is probably what is happening to you.
You also haven't mentioned the programs that you are using during the day. Some programs, particularly chat clients, will drain the battery in about 5 hours, though obviously you're not using anything like this while in flight mode.
One more thing. You noted that you were told that leaving it on the charger whenever possible is the thing to do. This is incorrect. The more the battery is exercised in this way, the shorter the lifespan of the battery will be. With any mobile device we're all bound to charge it every night, but once it is charged you want to take it off the charger. A battery being fully charged is just as bad as a battery being fully drained, so you want to keep it somewhere in between as much as possible.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
