Should I change to iPhone 6 Plus from my iPhone 5s or maybe I should wait for the new iPhone?

If your phone is working fine, why replace it? Under what circumstances do you think getting a new phone is something you should do?

Up to you.

6 Plus now or (assuming) 6s Plus in September (3 months)

Iphone 5S is a great phone so I wouldnt be in any rush, its not like yours is outdated.

You should wait, there's not a big difference between the 6 and 5s, so wait for the 6s to come out and upgrade then
