I’ve had my iPhone 6 Plus for about 2 years now and it is still going strong. The 8 megapixel camera still does a good job taking photos. The camera is far better than my iPhone 4S. The iOS is still rock solid and relatively fast in spite of the fact that this isn’t the latest phone from Apple. I don’t think I’ve ever experienced a freeze or hang-up requiring me to restart my phone. Due to the large screen of the 6 Plus I used my iPad Mini less and less to the point that I gave it to my wife who uses the Mini for games.
I have yet to experience the force touch feature or photos that move for a few seconds so I don’t miss the features that were hallmarks of the 6S Plus. Frankly considering that my 6 Plus is only the 16GB version I’m glad that it only has the 8MP camera because I’m not able to store many photos on the phone before I have to save them to my Mac. If I had the 12MP camera of the 6S Plus the issue of space for photos on the iPhone would be that much more critical. For reference I have 3 full pages of Apps loaded on the phone most of which use around 50MB, none are space hogging games.
The lack of space for apps and photos on the 16GB version is probably the biggest fault of the phone. I imagine that the iPhone 6 and 6 Plus will be taken off the market as new stock and only available as used or refurbished once the iPhone 7 and 7 Plus come out this fall. Should you want a quality iPhone on a budget between now and when the iPhone 7 series debuts I would highly recommend you get the 32GB version of the iPhone 6 Plus. If you don’t care for the larger screen then get the 32GB iPhone 6.
