“If you’re anything like me, you have a number of gadgets within arms reach that are either on charge right now, or will need charging at some point during the day,” Adrian Kingsley-Hughes reports for ZDNet.

“As regular readers will know, I’m a big fan of real-world testing. The only drawback of real-world testing is that my “real world” is going to be different to your “real world,” which means that your mileage can, and probably will, vary.
