To begin, the iPhone 6S Plus is a phone that is on the heftier side, standing at 5.5 inches and weighing a whopping 6.77 ounces. So not only is it big, it is heavy. For reference, the iPhone SE weighs just 3.99 ounces. However, with this size comes 1920x1080 resolution, which is a welcoming change from the iPhone 6S. In addition, it is also identical to the iPhone 6 Plus in terms of design.
Furthermore, the iPhone 6S Plus runs with the A9 CPU and 2GB RAM, which does not falter in today's smartphone world. In other words, you'll be able to run apps without any issues, and you won't suffer from any slow down with the iOS 11 update.
In regards to battery, the iPhone 6S Plus runs on a 2,750mAh battery, which ensures greater longevity on a single charge when compared to the smaller iPhone 6S. Overall, it's certainly an improvement compared to predecessors. This is also thanks to the A9 chip, which is more power efficient.
With the iPhone 6S Plus' camera, you'll have faster shutter speed and crisp visuals, even with the 12-megapixel sensor - which is still behind Sony's and Samsung's cameras. Furthermore, the front-facing camera has been improved, standing at 5 megapixels compared to 1.2 megapixels.
The iPhone 6S Plus isn't vastly different from the iPhone 6S, but it does stand out from competitors with its 3D Touch, shutter speed, and A9 chip but it is a little heavy and bulky, so if you're not a fan of larger phones, you should look elsewhere. However, if you're looking for a used iPhone 6S Plus at the best price, then you should refer to the online market for the best prices.
You'll find iPhone 6S Plus models for sale at a cheaper price online compared to what you would find at a physical retailer. However, it's also important, before you buy, to compare prices of refurbished and unlocked iPhone 6S Plus models from the top resellers to ensure you'll receive the best price.
