There Is More to the Apple iPhone 6s Than Meets the Eye
With it you can take a quick look at the contents of a message without having to go through all of the steps required to open it. A similar feature in Safari lets you take a quick look at a Web page without actually browsing to it. Unfortunately, 3D Touch is only useful in a few of Apple's apps and currently is not supported in any other apps that I've found. This means that while you can peek at a message in the iOS Mail app, you can't do it in the Outlook mail app. Other important capabilities of the iPhone 6s include better radios, a more efficient processor and more memory available to the CPU. The iPhone 6s now supports LTE Advanced as well as WiFi in 802.11ac with MIMO antennas. Both of those standards promise faster speeds, and 802.11ac with MIMO supports multiple spatial streams for wireless networks, which boils down to better speeds and longer ranges. Apple's 64-bit A9 processor is said to be 70 percent faster than the A8 processor in the iPhone 6. In addition, the M9 motion co-processor is embedded in the A9 chip, which will speed things up slightly. Despite the much faster processor, battery life remains unchanged, although in real-world use, the iPhone 6s seems to do slightly better than the iPhone 6 it replaced.The radios, in addition to supporting LTE Advanced, also work on a greater number of frequencies than the previous iPhones. In fact, the only difference between the various models of iPhones is that the devices headed for AT&T include LTE Band 30 and the others don't. Phones intended for T-Mobile, Sprint and Verizon are identical. The phone's cameras have been improved as well. The iSight camera on the back of the phone now takes photos at 12 megapixels, and they can record HD video. A menu setting also lets the phone record UHD 4K videos at 30 frames per second. However, the screen on the iPhone 6s remains unchanged from its predecessor at 1,334 by 750 at 326-ppi resolution. As nice as this is, it can't show full HD or 4K in their native resolution. Overall, the iPhone 6s, and by extension, the 6s Plus, is a much more capable device than its immediate predecessor. It may look the same, but inside that sleek skin is the heart of a supercomputer and an advanced video system.
It's not uncommon to finish the day with over 60 percent battery life left. The new 2-gigabyte application memory space doubles that on the previous iPhones, giving apps a performance boost because of the extra space.
