New school year, new gear. Maybe you're due for an upgrade, or maybe you broke your phone over summer break, or maybe you just want a new toy. Either way, you might be looking to refresh your slate of devices before heading to campus. For the mobile section of our back-to-school guide, we considered the best phones you can get on a student-friendly budget. We also threw in our favorite smartwatches for both Android and iOS users. But "mobile" means more than just phones and phone-like things meant for your wrists. We also included our favorite e-reader and make a case for why someone might want to splurge on an iPad Pro. (Hint: art and design students might get a kick out of it.) We know that in your haste to get to class on time you might occasionally forget to charge your devices, so we've also included a portable battery that can keep all your stuff running. And life isn't all work and no play, so when it's time to chill out in your dorm, you can strap on our favorite wireless headset and take out some aliens in VR -- no need to make your roommate trip over any cables.
