(I not seen this raised so hope this is new)
So I see lots of threads about best phones and best Anker products, but for me this is the side story. The main story is about how big and how much functionality do you want in your phone?
If you look at a phone which can do it all you often end up lugging a large 5.5" (or worse 5.7" or larger) phone with you all the time, with pressure on battery life and so QC ( / Turbo charge / Dash charge) and Anker Powercore and Powerport.
Or you can go with the two or more devices option with a phone focused on a bit more minimalist, 5" max and carry a tablet which complements the phone. You add a device with a much bigger screen (7" minimum) adding its battery capacity and you can do 2 things at once easier. The downside is carrying 2 devices.
I tend to be most often with a bag so the tablet is in the bag, the phone in pocket/hand, and the times I am no-bag I welcome a good battery life smaller screen phone.
I keep coming back full circle to 2013 being the right approach a Nexus 4 and Nexus 7.
I see the “I would never have a phone that big” end up the norm, and it keeps going. Norm now is 5.5" and yet when they came out most said too large. I saw same before that with 5".
Now you struggle with some brands to get smaller phones.
Are you prefering to lug a big phone and it be your only device, or a phone+tablet and if so a smaller phone + tablet or a larger phone + tablet?
I have had enough with lugging my OnePlus2 5.5" around for a year and moving back to a 5" which lasts a lot longer on battery, I have a tablet with me. My fave is Pixel C which is basically laptop and my Nexus 7 (trusty ole 3 year tech)
