Should I upgrade?

Depends on how happy you are with your 6. We don't know what the 7 will bring...just speculation at this point. But, if you are tired of your 6, go for the 6S Plus right now. Look on the bright side, you'll be getting the 7S plus in Sept 2017, which will fix some of the flaws in the 7 Plus in Sept. 2016.

 

Do you want the bigger screen? We're literally 5 months from the 7.. You sure you don't want to wait?

 

You can upgrade that all depend on how you feel comfort in 6 version

 

yes you should. then perhaps, maybe not.

 

Get the 6s plus now and then 7 plus when that comes out. Then preorder the 7s and so on and so forth...

 

There will always be another model just around the corner. Upgrade now.

 

I suggest waiting for the 9S

 

6S Plus has more powerful chip, bigger screen and longer battery life, if you like the size and decide to go with a Plus since now, I suggest you to upgrade. Think about this, when 7S Plus is out, you can get a better price by trading in a 6S plus than 6.

 

You don't have to trade it - you're just responsible for the remaining balance. Sell the phone outright and use some of the money to pay it off.

If you trade in a phone that's almost paid off, you're essentially giving away money. To me it only makes sense if you trade right when you're eligible and the balance is still high enough to make it worthwhile. For example, if you trade right after you're upgrade eligible (month 12 of NEXT 12 when you still have 6 months of payment remaining.)

 

I'm waiting for the 10S Plus Pro
