It's normal. The battery meter on the iPod 5 is an odd little thing, shows estimated time of useable battery life based on current application and power consumption. So if your iPod is on standby lets say it shows 85%. Start watching a movie or playing a game and it drops to say 60%. Stop watching the movie and start listening to music and it goes back up to 75%. My guess is that is why Apple uses a battery icon and not percentages; it will make you Nuts! Don't worry about it, the only percentage to watch for is the 20% low battery warning, which can be annoying, think of it as a low fuel warning light in your car's fuel tank, doesn't say when you'll run out of gas, or in the case of your iPod power, only that it's soon. If you can, switch back to the battery icon, "and forget abou' it!" Cheers! Hope this helps.
