If you're using a 6/6 Plus, you should be able to last till the 7 or 7S (if my phone is really holding up i may hold on till the 7S as well). Cause from here on out is merely incremental upgrades, nothing major from what i expect.
Since they did not change anything since launch, i would say yes; bendgate is still an issue and a risk the 6/6+ will have to face. It's just that most of us here are extra careful, with their Lifeproof lah, Thule lah, Tough Armor this and that lah haha. Or we're just plain lucky..

hmm.. not sure what is the reason for the price drop..

My iPhone 6 just switched off on its on and now it can't be turned on. HELP

I tried hard reset and finally I managed to switch it on.  This is not the first time my phone switching off on its own already.  What is the problem?
