Not if your goal is to save energy, as the drain is beyond minimal.
Now, if you're worried that a plugged in charger is going to burst into flames in the middle of the night, set fire to the house, and kill you and your loved ones … well, that's a different research question.

Tested: Should You Unplug Chargers When You’re Not Using Them?
How much energy do your smartphone, laptop, and tablet chargers really use? Should you unplug them when you aren’t using them to save power and money? We measured exactly how much power a variety of common chargers use, and how much keeping them plugged in will cost your each year.

Oh wow interesting. I usually take out chargers and flip off my power strip because more concern of they burning out cause of the LED lights and stuff
Also a couple times a power surge or something popped a power strip and melted strip plug ins and the charger but they still work haha
+Dark-Ao Raiden-X Well, if you have regular power surges and problems, then unplugging stuff makes a lot more sense. 🙂
I actually wonder if the real reasons the products tell us to unplug things is liability concerns. It's rare, but chargers can short out or overheat and cause fires.
As an electrician, I agree; but the low-quality chargers with fragile capacitors in them heat up and shorten their life. Anything cheap is "cheap". Get a good line conditioner – this is the best for the money http://www.cyberpowersystems.com/ often the 1350 volt-amp (think "watts") model is $100 or less on Amazon.com or newegg.com when on sale. Plug your things into one of those for equipment protection and proper line voltage control. High AND low voltage variances damage all electronics
