Been using the iPhone 6s for the past few days and the battery life just about matches the MAXX. The MAXX is just the perfect size, I find the 6s' screen a hair too small. The 6s+ is way too big for me to carry around, more for women w/ purse. The iPhone is definitely snappier than the MAXX but is only really noticeable when multitasking or working the phone hard. Normal use, the Exodus ROM and Megatron Kernel runs extremely well. The main difference between the MAXX and the iPhone is the camera. I cuss out the MAXX quite often when I'm trying to capture a moment and the camera fails me by either initializing too slow or snapping crappy blurry pictures. No longer an issue now that I have the 6s, the camera is incredible. I'm going to order some Moment lenses and put the DSLR away for good. Overall, I still love the MAXX. I expected to be blown away once I made the switch but that is not the case. I'm typing this on the MAXX, use it as a mini tablet. Carry it around the house as my chromecast remote and use it for other small tasks such as browse forums with Tapatalk. The battery lasts forever in airplane mode. Other words, if it was not for the crappy camera, I would put the iPhone on eBay and keep using the MAXX as my daily.
