Your shorts and sleeping bag can now both recharge your smartphone
Imagine being able to recharge your phone simply by sticking it in your back pocket and walking. Now imagine that you're taking a camping trip and you don't own a generator, but you wake up every morning with a fully recharged smartphone because of your sleeping bag. Vodafone is testing both in the U.K. during the Isle of Wright festival that runs from this Thursday until Sunday in Britain. 

The Power Shorts and the Recharge Sleeping Bag, as the products are known by, were both developed by the Electronics and Computer Science Department at the University of Southampton. The science behind them is interesting. As the fabric that they are both made of is squashed or deformed, it "harvests kinetic energy" which powers up your phone. At the same time, temperature changes experienced by the sleeping bag also help power up your handset.

One day walking around in the Power Shorts will add four hours of battery life to your phone while the sleeping bag returns eleven hours of battery life to your device. Both the shorts and the sleeping bag will be in use during the U.K. festival, so even if the music is bad, those wearing Power Shorts or using the Recharge Sleeping Bag will at least be able to play Hanging with Friends all weekend.

I don't think the note 3 will need this considering how good the battery life on the note 2 is

I wont put a phone in my butt pocket. That;s merely inviting pickpockets to steal your device.

You worry too much about pickpockets, I would be a lot more worried I forget I put it there and sit on it!
So no, I would never put the phone in the back pocket.
