Welcome to our annual New Smartphone Set Up Guide. Someone thought enough of you to help replace that dumb ol’ brick you’ve been lugging around these past few years. Now what? Out of the box, most smartphones aren’t all that smart. In fact, many can be downright idiotic. Prepping your new pocket ‘puter means some hand-holding, which also means slogging through a checklist of occasionally tedious (but necessary) steps. Don’t worry, we’re here to help. Remember, this device will be your constant companion for the next year or two. So you’ll want to start the relationship off right. Regardless of the specific smartphone you received for the holidays, the weakest link is likely its battery. Treating your Li-ion with respect will not only extend the life and usefulness of your new phone, but also boost its resale value—just in case you decide to dump to back on the market prematurely.
