Fully Charged and only lasts an hour

The battery should be charged overnight ie for approx. 10 hours.
When the battery runs down then charge it up again until it is fully charged, you may need to do this several times until the battery reached it normal capacity.

According to the manual found here: http://manuals.info.apple.com/en/ipodshuffleuserguide.pdf

"Remove the USB cap and connect iPod shuffle to a high-power USB port on your
computer. The battery status light on the back of iPod shuffle turns on.
The iPod shuffle battery is 80-percent charged in about two hours, and fully charged in
about four hours.
When the battery is charging, the iPod shuffle status light is amber. When the battery is
fully charged, the light is green until you disconnect iPod shuffle. If you don't see the
status light, try another USB port on your computer"

Batteries also wear out from time to time, so if you find that it's not charging no matter what you do, it's likely that you need a new battery. Here's a link to more info on iPod batteries: http://www.apple.com/batteries/ipods.html

its either your battery that needs to be replaced or your charger it's not working

your battery is dead. fit a new battery, or take it into a shop and get them to fit a new battery. I had the same problem with mine (ipod video) and its been perfect ever since.

All you can really do is make sure the iPod is fully charged before watching.  Video files require more system reosurces than music files, so it is very possible that it will run down in a couple of hours or less. There are no longer-lasting batteries that can be used with this particular mp3 player.

You could try restoring the software back to factory defaults and see if something is missing. Make sure it is fully charged before doing it.

Hold down on the center button while hold down on the menu button. The apple logo will appear. Your Ipod is now rebooted.

Is the new battery fully charged? Usually it takes 6 hours on a new battery.

1. totally discharge the battery so it wont come on.

2. Charge the battery fully

3. Reset the player

Now check how long the battery lasts. If it is still 2 hours there is a problem with the battey and you will need to return the player.

replace the mobile phone charer and then try
