There are plenty of ways to manually boost iPhone battery life, including these seven tips for advanced users. However, the iPhone 6 doesn't have a comparable battery saving mode to the Note 4's Ultra Power Saving mode.
6) Samsung Galaxy Note 4 and Selfies
Just about every smartphone on the market today has some sort of selfie-specific camera features, but the Galaxy Note 4 takes selfies to a whole new level. It has one of the higher-resolution front-facing cameras on a phone today (3.7 megapixels, compared to the iPhone 6's 1.2 megapixels front camera), plus a wide-angle selfie mode lets you fit more into your selfies. The device even has a rear-camera selfie mode that lets you take advantage of the higher-quality 13 megapixel rear camera and helps you position yourself in the images, in an effort to get the background you want. You can also use the Note 4's voice controls to snap a selfie. (Telling Siri to "take a selfie" merely open the iPhone's camera app.)
Megapixels really aren't everything when it comes to digital cameras, and honestly, the quality of selfies I took using the Note 4 and iPhone 6 was similar. The Note 4 seems to capture more life-like lighting conditions, while the iPhone appears to capture more detail.
