4th update

Received a phone call from Apple, they told there is a 3 spot's area where they found 'water damage' @ water patch  

I insisted that i took care of my item properly & more over i keep the iphone in the water resistant casing.

So, she told she can give me one time exception to service the iPhone (means exchanged but only phone, not full set with box). They replacing with exactly the same unit 128gb of ip6s BUT Japan unit (my phone is Japan's unit). They asked me do i have simcard to activate the phone. Damn!!! I cant fly all the way to Japan just to activate the phone right? 

Any advise?

p/s: good news, but still finding solution 

anyone experienced where your phone shutdown automatically when battery is at 7-8% left?

not all the time but happens randomly....

exactly, mine shutoff at 30% as well. But workings well when plugged in charger

There is a different between refurbished by Apple and refurbished by unknown (which is 3rd party).

The one that give a lot of problems is refurbished by unknown.
By Apple itself, well, all's confirm original, under warranty, perfect but used/changed parts.

I've used refurbished from Apple twice, all's good no problem at all.

Are u guys mostly already sold to 7? I guess this thread will be quiet when 7 is here

Next year? Means 7s?

iOS 10 battery life report:

5:00am - 100%
4:30pm - 1%

Big jump in performance but it came at an expensive cost.

Back when my iPhone 6S Plus was running iOS 9.3.5, it can last me the whole day with 30-40% to spare

EDIT: My usage is confined to social media apps and I was on WiFi 90% of the time
