Is is worth upgrading from iPhone6 to iPhone7?

Hey guys, if you had both iphone6 and iphone7, it is worth to buy iphone7, what differences betwwen them?
looking to buy it for me wife as birthday gift but but sure if is worth buing iphone7 or i should buy iphone6 since i like it

If you can afford the 7, buy it. If you can't afford the 7, buy the 6. 7>6.

Just asked to find out if the camera is a lot better or any other features that can justify the high price difference.

Its ment to be allot better but im not sure its worth the price

Your battery is prob f'n up. Apple programmed their phones to go out of date when a new phone is released.

Don't buy an Iphone 7, buy an Iphone 8 now or an Iphone X.

It's worth it to switch off Apple. Way too overpriced compared to the concurence and their level of technology

I think upgrading to iPhone is good value for money but you don't have to get a new one get the one from someone.

I kinda blend the 6, 7, and 8 together. If you are gonna go to 7, might aswell skip it and go to 8

I'd prefer switching to a different brand all together.
