In old Android phones you could even get those additional 3% by unplugging at 100%, seeing the battery immediately go to 97% and then plugging again. My old Galaxy S4 Mini would even report 94% in such cases - I originally found out about this due to this discrepancy.
The iPhone gives you more of a "gas tank" indicator, as in that 1% charge left is actually closer to 10-15%. Same with 100% - hell knows how much it really is.
