If you are constantly battling having too little memory on your iPhone 6 or 6S, then you’ll want to check out the SanDisk iXpand memory case. It can add up to 128GB storage to it, and it serves as a protective case.
Available in mint green, sky blue, red and grey, the iXpand case will make it easy to manage, view, and back up content. There’s even a 1900mAh add-on battery pack (sold separately) to extend the phone’s battery life! “When connected, the optional battery pack detects when your phone’s battery runs low and kicks in to charge it.”
You can automatically backup photos and videos to the case’s memory using the iXpand app; “the iXpand Memory Case includes the SanDisk SecureAccess™ software for Windows and Mac computers, making it easy to protect and access your files.”
