Battery percentage issue on both my iPhone and iPad?

This is the situation:

- let's say the iphone's indicator shows 80 percent battery.

- I plug it into a wall socket and turn off, reboot it.

- for some reason the indicator has gone down to like 76 percent, and slowly charges back up to 80 percent and eventually 100 percent.

this happens on my ipad too.

- does anyone else have this issue? It's annoying since it means that the indicator isn't accurate.

i update the iOS on both devices to see if that would fix the issue… It DID NOT!

is Apple aware of this problem?

Added (1). since it's RECEIVING electricity, shouldn't the percent either stay the same or GO UP? Why on earth would the percent indicator suddenly show a much lower level?

How do you record a game on iPhone?

I figured out how to record the screen and sound. The only problem is when I do that I can't hear the game as I'm playing it. How do you record screen and sound but still hear the game?

What's wrong with Facebook? - 1

My Facebook on my iPod today hasn't been loading the news feed. It's been doing it all day even if I log out it doesn't work. I'm not getting an iPhone. What's going on with it? Anyone else with Apple have this problem?
