iPhone 14 Plus battery lifeApple's iPhone 14 Plus offers the longest battery life among its rivals. The new model can last for 100 hours of music or video playback. That's an impressive amount of time for a smartphone, and it's also five hours longer than its predecessor, the iPhone 14 Pro Max. Even when you're chatting with a friend, the iPhone 14 Plus will still give you plenty of time to charge.Speaker holesLuckily, you can easily clean the speaker holes in your iPhone 14 without removing the phone. To get started, you need a small brush, preferably made from a soft bristle. Make sure the bristles are about half-inch long, and then gently brush the speaker holes from bottom to top. Try not to push or rotate the brush, as you might damage the speaker. After cleaning the speaker holes, you can use a toothpick to remove any debris that's stuck inside.The iPhone 14 does away with the traditional SIM Card slot. Instead, it relies on eSIMs. You can add an eSIM from the Settings app, and you can carry up to eight lines of service. However, you can only have two active SIMs at one time. eSIM is still not universally supported by all carriers, especially smaller ones. But, the technology is gaining popularity.DisplayApple has made some changes to the display on its latest iPhone, the iPhone 14. One of the biggest changes is the addition of an Always-On display. This display is enabled by default on the iPhone 14 Pro and iPhone 14 Max. To turn off this feature, first open the Settings app (represented by a small cog). Then, select Display and Brightness. You'll see several options for the display, including an option to dim it to 10-20%.Bluetooth 5.3 radioApple's iPhone 14 lineup has Bluetooth 5.3 radio support. It's the newest standard for mobile phones, which also helps the device use less battery power. It also supports AAC, Apple Lossless, FLAC, and Spatial audio.CameraThe camera on the iPhone 14 is much improved over the camera on the iPhone 13. It can take better pictures in low-light conditions and is faster. It also has a new marquee feature called Action Mode. Although the viewfinder is similar, the new camera has been slightly shifted. This means that iPhone 13 cases may not fit the new model.Crash DetectionApple's latest iPhone 14 has an interesting feature called crash detection. The feature uses several factors to detect a crash. If your phone detects a crash, it shows a 10-second countdown before contacting emergency services. However, it is not entirely accurate, as there are cases in which the phone may not detect a crash at all. Nonetheless, it is a useful feature that could potentially save your life.
