Over to robin. To our new series connected for life. Becky Worley is back to show us how to charge your phones and charge them fast. It's a story we first saw in "The Wall Street journal" and Becky has the secrets. Reporter: The dreaded dead battery. When cell phones hold our entire lives, schedule, directions, phone number, a dead battery makes you dead in the water. But when you feed to recharge fast, hurry up, phonemakers are trying to help, android phones offered fast charging since 2013 and now the iPhone 8, 8 plus and iPhone X offer similar options. But -- Fast charging isn't included in the box. Reporter: We purchase a 29-watt charger and special cable from apple for $74 and then with two brand-new iPhone 8s, completely dead and out of juice and two chargers, you've got -- I have the 5 watt charger included in the box with every iPhone. Reporter: That's the free one. I've got the fast charging gear that we bought so let's plug them in and see what happens. Sure enough, all right. We are at -- Moment of truth. 30 minutes and -- Oh. Fast charger, 52% charged. Standard charger, 32%. 32. Wow. It takes the standard charger another 25 minutes to hit 50%. But 74 bucks to charge 20 minutes faster? Do you have to buy apple's gear? No, definitely not. That doesn't mean I think you should go out and buy the random charger on the treat or from the drugstore but look at trusted brands. Reporter: We drained them dead and try this $11 charger from anker and uses the standard apple cord and do it alongside apple's high speed charging gear. After 30 minutes -- oh, wow, 57% for the anker charger and 53% for the apple fast charger. So you may not have to spend big to charge fast. Now, one note even though we used a cheaper charger from anker all of the cables we used were from apple and you do have to be careful with third party cables. They can hurt your phone. How does the fast charging affect the battery life? Now the software in the phone is so smart that it takes care of the battery life and health. You don't have to worry about it. Only goes up to 50% on the fast charging. Thanks so much. Appreciate it. Get all of Becky's tips on our website, goodmorningamerica.com. Over to ginger now.
