Given that many people aren't seeing this type of thing, it's not likely something simple or even relatively easy for Apple to investigate, let alone do something about, at least not in any sort of quick manner.
Seriously?More excuses?Theres already many in this thread having similar battery life to me.You must be owning some magical iPhone if it lasts all day with no charge
 
@starikarp hard reset is not what you think. Press home and powerbutton at the same time till phone turns off than press powerbutton. IOS does imaging if you just power it down. With this method every process is being killed. You loose NO DATA

Sure, that's it, me and many many other people.

I did it before and it didn't work.
 
I have the same problem too on 6S. I made a clean install and last night without even touching the phone , the battery drained by 10% in 8 hours. Battery stats is also wrong though.

I am always able to get around 8 hours of battery life on my iPhone 6, with mixed usage (wifi/4G) sometimes in bad network conditions. Background refresh is ON for few apps only, location services are all ON. I always turn low power mode ON at 20% remaining. Bluetooth is always ON because of my Apple Watch. One year ago I was easily able to reach 9-10 hours with 36+ hours of standby, but it was with iOS 8, without Apple Watch, and the battery was brand new. First two screenshots on iOS 9.3, last two screen shots with iOS 9.3.1, and not much differences between the two.

9.3.1 is definitely causing battery drain on the 6s while on standby / overnight

I thought that was normal. My 6+ does that too.

That's not actually normal atleast for me. I did not even touched the phone in the last ten hours and the battery down by 10% with battery usage of >3 hrs. I downgraded to 9.2.1 and the battery stats is normal. Background refresh is off but the location services is on though .
 
I was never a person who complained about battery problems.
But since iOS 9.3.1 it's horrible for me... Really annoying
 
Mine went from 85% to 49% in a few hours and phone was getting hot since I updated, so I did a full factory reset last night, I'll see what that does. The phone had a very bad lag to. I'm using a iPhone 6 plus

My phone too getting hot on 6S with clean install. I noticed this on both 9.3 and 9.3.1 but not with 9.2.1 though!
 
I know 9.3.1 hasn't been out for a long time, but I want to know how the battery life on a 6s is, specifically if it has a Samsung A9 chip. I have 9.2.1 currently and battery life isn't great. Is battery life better than 9.2.1 or 9.3?
