Close running apps

Bummer. Are you syncing from a previous iPad or downloading a lot of new Apps? That can use a lot of battery and should be a temporary condition.
Look at this and see if it gives you any ideas

1. Launch Settings from your Home screen.
2. Tap on Battery. Wait a moment for Battery Usage to populate.
3. Tap on the Show Detailed Usage button to get a breakdown of foreground and background power usage.
4. Tap on Last 7 Days to get a broader look at power consumption over time.

A few suggestions:
1. Ensure you are using a good (fast) wifi connection.
2. Make sure there are not too many apps running in the background on the tab at the same time (using resoures). Close unused/unneeded ones.
3. Check for updates to your tab's system software. If available install the latest update.
4. Log into Facebook with a browser app instead (i.e. chrome, firefox, etc.). Check if there is a problem after 30 min. or so accessing Facebook this way.
5. A full system reset will probably fix the problem (unless there is also a hardware component problem with the tab). But it is a lot of work to reinstall apps, accounts, etc. (... consider only as a last resort).

Some app is running in the background. Go to settings>apps> and close/disable any app that uses the camera. Then restart the app that you want.

Try restarting your tablet if it still is not working try restarting it again unstall a few apps download CM security app this should help speed up things on your tablet CM Security Antivirus AppLock Android Apps on Google Play if it keeps up try backing up your data on sd chip and factory reset your tablet good luck!!

I charge my iPad during the night so that it's ready for me in the morning.
With regard to discharge times, this is dependent on the number of Apps you have open and what other service you have running.

When you have finished with an App, press the home button twice and close each of the Apps by swiping upward on the screen. This will close the App completely, until you are ready to use it again.
Also check that Bluetooth is off when you are not using it.(go to Settings - you will find the Bluetooth switch there)

You may need a new battery.

When you open an app it is using memory. You can free memory by closing apps that are still open:
1. Press the home button twice quickly. You should see all the apps that are open, appear in small windows.
2. Grab an app with your finger and drag it to the top of the screen then let go. It closes the app to free up memory.
3. Use this method to close The rest of the open apps and then click on the remaining desktop to open it.

There's also an app that i use to free up even more memory. It's called BATTERY DOCTOR HD. Along with a battery tool, it has a tool that frees up memory. You may want to give it a try. I hope this has been helpful!

Have you tried turning off background apps.
Bring up your recent apps usage with the touchscreen button that looks like 2 windows,when you see the list of apps put your finger on one and swipe left or right ,this should close the app .
Try using Task Manager also to close anything unwanted.
Look for an app called" Wake Lock Detector" ,It can tell you what is running in the background using up battery power.
Hope this helps, even if it is a bit late.

I'm not that good with android tablets, but is there a way you can remove the battery? and then replace the battery after a little while?
When some app is blocking mother one, you should try to reset the tablet and start from scratch. Try to close apps when you no longer use them.

The battery may not be charged good or you have an app that is running and using your battery up. Go into your settings and then tap applications and you should have battery usage which will show you what is using your battery. If it is an app you may have to uninstall it or force close it.
