With iOS 11, Apple adopted the High Efficiency Image Format (HEIF) as a replacement for JPEG on both iOS and macOS. The HEIF format saves a considerable amount of storage space with its .HEIC files (High Efficiency Image Container) being up to 50 percent smaller than the same image saved in JPEG format. Despite the smaller size, the HEIF format can capture 16 bit color whereas the JPEG only handles 8 bit. Clearly HEIF is preferable to JPEG right?

Out of nowhere this week Nintendo released Dr. Mario World for mobile devices. This is the second iOS title to star Nintendo's mascot, Mario, the first being Super Mario Run. Unlike Super Mario Run, which was $10 for the full version, Dr. Mario World is free to download. Nintendo figured out there is more money in microtransactions than charging a one time premium fee. You can download the game from the Apple App Store.
Control Center has always offered the ability to quickly disconnect from WiFi or Bluetooth, but with the release of iOS 13 you can now quickly change WiFi networks. This is useful for a variety of obvious reasons, such as transitioning from your WiFi network at home to outside connections like work. Instead of navigating to the Settings app, you can now switch networks with a swipe and couple of taps. Here's how:
You can personalize your information in Settings > Messages > Share Name and Photo. From here you have the option to select "Everyone" under the Share Automatically options. You will stop receiving notifications if you select this option, but then your phone will automatically share your name and photo with everyone you text message. This is not recommended.
