THAT’S FAST

Joy’s nephew recently graduated from a flip phone to a smart phone. The one thing he misses is the long battery life of the flip phone. What if you could fully charge an iPhone in five minutes? A charger that can do just that is slated to come out in August. This idea so electrified (so to speak) the Kickstarter community that “Pronto,” the forthcoming fast charger, quickly raised $375,249 in seed money. (That was $325,000 more than they were looking for.) The basic device will cost $89 and hold three charges. The super model will hold nine charges. Either will fully charge an iPhone in five minutes. You can pre-order one for June delivery from pronto-battery.backerkit.com.

Our phone stays on for at least 18 hours now, with light use. Some apps, such as the Amazon Kindle app, take a little longer to load with Greenify running in the background, but that’s better than a phone that dies when you don’t expect it. Before Greenify, we tried several other battery life extenders: […]

CHARGING YOUR PHONE

Our new Galaxy S3 phone has a removable battery. So rather than carry a charger or a cable to plug into a wall outlet, we carry an extra battery. But most smart phones and tablets don’t have this option.
