Default [Q] Out of Box, battery not charged?

Very silly question...

Just arrived today. First ever tablet for myself. Bought the wife an ipad2 for xmas and, out of the box, it was 80% charged, ready to go. My TFP is only 4% and I am having to charge it before using it.

Normal?

That is normal for any electronic device. In fact, in the manual it will probably suggest that you fully charge it before you turn it on.

Batteries lose their charge over time even when the devices are not turned on.

Also something you should know, all electronics typically require a period of conditioning of depleting the battery to 10% and then fully charging it to 100% while powered on (but not being used) to gain their maximum battery life.

So basically:

1. Use it to 10%,
2. Plug it in while it is "sleeping", (not fully turned off but not being used)
3. Charge it to 100% then repeat the process a few times.

You will get your optimum battery life at that point. (Also, specific to the transformer you should leave it on the middle power setting (balanced) mode). Normal mode is actually a battery drain, they should be or already have changed that in an update to "performance".

Mine arrived dead.

All the guys in the office crowded around for the unboxing and when I pushed the power button I got 1 second of a big red battery icon in the middle of the screen and then nothing.

Was good for a laugh, no battery issues after charging it up.

Mine had about 30% charge.

Lithium Polymer batteries should have a full charge up before beginning inner cycle charging.

To expand on this, how long does it typically take to fully charge? I'm receiving my TFP tomorrow while I'm at work, and will have about 3 hours of charge time (give or take). Should I wait until I get home to start the charge process?
