I have been on a 6S for the last 2 years and ready for an upgrade. I have also (through the ravages of age) suffered a deterioration in my eye sight so have been looking to go with the bigger screen model. Looking at the 8 Plus as the X is way too pricey.
The camera(s) is the other reason I am justifying the update. All the reviews and comparative images I have seen have the 8 Plus blowing the 6S out of the water.
I also upgraded to iOS 11 overnight. So far so good.
If I were upgrading, thatās the one Iād go for, and for the same reasons. Also, hopefully to get longer battery life. My 6S seems to run down more quickly these days.
Quick question for the folks here who have the larger āPlusā models. How comfy is it to fit in your pockets (front ones)?
I hated it at first.
But the benefit of the screen size meant I no longer needed the ipad mini.
The only time itās in my pockets is during summer but Iām usually in cargo shorts so it isnāt a big issue. In winter itās in my jacket pocket. The size and pocket thing isnāt a big issue for me.
Just get the simplest and slimmest cover possible. Iāve been used to putting membership cards / cash in my phone cover so I donāt have to carry a wallet in my pocket for small purchases.
Iām in the same boat. Have had the 6S plus for the last 2 years and loved the battery life etc. Looking at upgrading at the end of the year if the 8 is any good. New iOS update is slick.
Never had an issue with the size, I have large hands so feel itās to scale, everything I see thatās smaller looks weeny.
Cāmon mate, no need to brag 
Assumed iOS 11 would run like a dogās breakfast on my 6plus but has held up well.
Got the 8Plus over the weekend. Quick thoughts:
New Apple watch goes Dick_Tracy. Thoughts?
Same here. It actually feels a bit faster, but that may just be my active imagination.
On the other hand the battery life seems to be getting shorter.
Does anyone know the best supplementary charger for a 6S? Ideally it would take the form of a case for the phone, and if my phone was getting low all I would have to do is put it in the case and it would immediately give extra battery life. And it would at least double, preferably triple, the life. And not be too bulky
I know there are Mophie cases which do this, but the problem there is that a change in the shape of the phone means the Mophie is now useless.
I moved to a Cygnett which is an external beast holding charge. You then charge your phone with a USB charging cable, as if youāre charging through the power point.
I know the Cygnetts are much smaller now.
Sounds like youād prefer something like a Mophie, but be warned about phone upgrades. And if you buy a Mophie, buy it from an approved Apple reseller. The lightning connection must be approved or just wonāt work.
Thanks. Will investigate
Bumpity bump bump.
Anyone had trouble restoring a 6s backup to a new 8? itās been an absolute clusterfark. keeps either hanging and doing nothing, or says the phone is locked when it clearly isnāt. iāve restored a few iphones in the past, but this one sucks. one did run, but nothing transferred over.
iāve updated ios on both phones, itunes up to date, reset rinse and repeat. so frustratingā¦
Exact same thing happened to my wife. Here is what worked:
Good luck! It really ā ā ā ā ā ā me off spending over 4 hours to get my wifeās new phone to work!
cheers! i havenāt tried wiping the 6s backup, iāll give that a go tonight!
didnāt help that my wife had never backed up her 6s, and had about 30mb of free space left on it. 
I donāt recall having any issues at all.
I also didnāt have any problems, but thatās because I decided to keep my 6S and not upgrade. After looking at an 8Plus I decided it just wasnāt worth it. Iāll take advantage of the cheap changeover battery sometime soon, but really the 6S does everything I want. I know there are lots of differences between a 6S and an 8Plus, but apart from the screen size they wouldnāt really improve anything much for me.
When i smashed my screen on my 6 over christmas and got it replaced, repair guy said battery will probably only last another 6 months as it had a swollen battery.
My battery life has been pretty crappy, seems to be on charge at work most of the day then overnight as well.
