I am looking to part with my DSLR and upgrade my smartphone(iPhone 6s plus) to something with a better camera. Looking for a phone with a low f number(1.8 ish) and a strong battery. I’m considering an iPhone 7 plus, 8 plus, iPhone X, Google Pixel XL or a Samsung Galaxy S8. Can anyone suggest something I’ve missed or give any advice from personal experience? Or if you see a good deal please let me know Thank you!
