I have been having a few problems regarding the battery life on my new iPad.

Firstly, When I charge it, it reaches about 96% then the sign changes from the "charging state" (the lightning bolt) to the charged state (the plug symbol)...However, it keeps charging. (The numbers keep increasing.)

Secondly, as soon as I unplug my iPad from the charger, the percentage decreases from 100% to 99%. Is this normal?

And thirdly, the battery life decreases rather fast...like in 5 to 10 minutes, one percentage is lost and only one app is open. (IM Pro).

Can someone help me with my problems here?

Average 7.5 minutes.

7.5 x 100= 750

750/60 = 12.5

So, that's 12.5 hours battery life with very light usage. Seems about right..

Oh ok...thanks for breaking it down for me. But what about the issue where my battery life decreases the second I unplug my charger?
 
Battery life is not linear so you cannot just take the duration of 1% and multiply by 100. Sometimes I have 75% turn off and on, and I have 77% etc. There is no way of precisely measuring

I think this is pretty normal. Think about it logically, you're battery can never be at 100% unless it is plugged in. The second you unplug it, it's going to discharge even a tiny amount and then it is no longer at 100%, might be 99.8%. Considering it only shows whole numbers, it must round down to 99%?

Unless you just relax you will not enjoy your new toy!

Just use it like there is no tomorrow.

I'm definitely enjoying it...I just intend to get my money's worth when I spent all of this money on a product. But trust me, I'm enjoying it the most I can.
 
Many times battery issues can be addressed by doing a hard reboot. Just hold down the power and home buttons at the same time for about 5 seconds until it turns off on its own, then turn it back on. It will take a little longer to reboot this way, just give it a minute.

This is not "slide to turn off", keep holding them until it just turns off on its own to a black screen.

true but they are normalizing the discharge curve and it even has a little learning component hence the advice off and on here let it see a full discharge under 20% to read accurately.
 
I had 3 iPads so far, one took a very long time to move from 100% the other jumped down in a minute, so it does vary.
