No. And by "no" I mean "hell no".

When I read that information I had a thought I've never had since I got my first iPhone (about 2011 I guess). That iPhone is heading in a wrong direction. And maybe it's time for a change.

I want my iPhone to survive at least one day of heavy usage without looking nervously on the battery indicator. And that's currently quite not possible (iPhone 6) despite I completely turned off background refresh, fetch for most of my accounts, most of notifications etc. I still have to care.

I'd like to have at least 20-30% of "reserve" for unpredictable situations. And be able to use background refresh at least for few apps. I think about 2200 mAh would be enough for 4,7 inch iPhone.
