It was a pleasure to visit Tech Columnist Joanna Stern at the Wall Street Journal with Marlo to talk about the latest technologies and gadgets. Battery life for your phone is important, especially if you are constantly on the move. Joanna, who had 40% of her battery at the time she came to the show, gave us some of her extremely helpful energy-saving tips, such as screen brightness and closing apps, to keep your battery life longer. For more of Joanna's helpful tech tips, check out the videos above. Do not forget to like us on Facebook and submit all your questions on Monday with Marlo for our future guests!
