I don't think that's true. The battery is at 100% when each cell is at 4.2V. You can charge beyond that, but any properly designed charging mechanism will prevent it, since you'd probably start a fire. If a battery meter tells you that you're at 100% when the charge is < 4.2V, then it's lying. Some devices do this in order to trick you into treating your batteries better, and others do not. It's hard to know if your device is lying unless you can measure the battery voltage and compare it to what the charge indicator says.
