Weird battery behavior

On the graph of my battery percent I have a couple of points where there is a slight peak as if I plugged in in for a minute but I didn't. Meaning I didn't plug in my phone at all but I get a peak on the graph. Very very small but still there. Anyone ever see this?
 
I'm using the extended battery and I see this all the time. There's often a tiny bounce back upwards, especially after a steep slope down when I've been actively using the device. Hopefully there's just some issues with how the OS is reading/interpreting the values from the battery that can be fixed (and not, say, an issue with the battery readout itself or there being funny voltage bumps due to a quirk with the batteries).
 
i'm using the stock battery. so i would assume its a software problem. lets hope so anyway
 
Battery voltage drops under load, so if you were doing something on the phone that resulted in high current draw the voltage may dip, then when you return to "idle" current draw the voltage will increase. I'm assuming the phone has an internal mapping of battery voltage to percentage, and that is what it displays, so if the voltage drops during use and rebounds, it would probably show up as the percentage increasing.

You can also notice it if you power off the phone, often the battery percent is higher when you turn it back on, since the load is less and batteries recover some voltage when not in use.
