Lol. What if they gave you a refurbished phone!

OK I bit the bullet and checked the swapped out phone in Coconut. Looks like I may have fallen lucky, unless Apple are able to reset the stats when they refurb. Which they probably can

A hard reset usually calibrates the battery I find..

A hard reset is the same as unplugging a computer (or holding down the power button on a laptop) without shutting down first. It's never a good idea unless the device is completely hung since it can result in lost or corrupted data.

Even Apple doesn't recommend doing that for any reason other than the phone not responding.
 
Just update to 10.1 Beta three days ago. The battery life is pretty good (by considering my 6+ is 2 years old, Battery Life estimate my battery capacity drop to below 85%).

This is my one day use, off plug for about 12 hours, 3.5hours usage, and 70% remaining. BT always on and paired with my Apple watch. Wi-Fi always on no matter where I am. LTE always on regardless signal strength.

Pretty good unless it's music taking up the usage... Also 6 devices seemed to less issues. It was the S models with a problem for some reason.

May be it's the new functions related (e.g. wake on raise). So, only the S model is affected.

I rarely listen music. My main use is Safari and Facebook (apart from the normal smart phone function e.g. Message, WhatsApp, making calls).

Anyway, the 10.1 Beta has new charge algorithm, may be that helps. I will ask my wife hows the battery and report back, she has the 6s+, and I also installed the 10.1 beta for her. She is a pure user, won't monitor anything, won't customise anything, and she usually stick with her phone for whole day. So, her comment should be quite fair. Anyway, wake on raise is disable on her 6s+, because she don't want her phone wake itself in her bag.

I've always had it off and I had issues...

Follow up to my last post, I'm sticking to 9.3.5 for a while until 10 has it's issues worked out. I don't want to miss the downgrade window and be stuck. Especially after it seems like security is more laxed in 10
 
Absolute Worst battery performance since owning this 6+ Pathetic
Running 10.0.1

Auto Brightness on, brightness set to 1/3

Battery life has taken at least a 30% hit since coming to iOS 10

Whats the best app to monitor my battery? I downloaded 'battery life' and the app says that my 6s bought in february has a wear of 13%. This is not normal right?

There's a few posts in this thread about it not being very accurate. Even the app itself says it can give different readings in different temperatures. I saw it go from 5% wear to 23% and back to 7% over a three hour window. IF you have a Mac (or access to one) try Coconut Battery but I don't know what might work from Windows.
 
Wonder if ios 10.0.2 improves battery life on the iphone 6s... I installed on the ipod touch 6 and i think it did on it.

iOS 10.0.1 destroyed the battery life on my 6s Plus but 10.0.2 has fixed it a little. I'm sitting here with 44 mins usage and 6 hours standby on 96%. I'd go into more detail over what I used during those 44 minutes but it's a combination of Phone, Messages, News, and Amazon.

Before upgrading to 10.0.2 I needed to put it into Low Power Mode all day to keep it charged.

All this is becoming a little mess, some people are saying they don't have any issues in fact they are getting better battery life on ios 10 and i believe them, now i'm thinking these issues are related to the model of the model. Iphone 6s have 3 different models, and different manufacturer processors (Samsung and TMC)....i have the samsung one on my iphone 6s and i rembember the best one for the iphone 6s (the faster) was the TMC one perhaps that's the problem or who knows...=(

I too have the Samsung model. It has always had worse battery life than the TSMC one.

I have the TMC chip. Running 10.0.1 with 6s. Think my battery is better. Not using raise to wake and turned off all the new message stuff.
 
I know, having good luck with 10.0.1 so I figured I would wait. I normally don't upgrade iOS for several weeks after it comes out, just wanted to try 10 and it works good for me.
 
Same issue here iPhone 6S and iPad Air 2.

Done this for 4 years never had a problem and I bet no one else has on a phone.
 
Having pathetic battery life on my 6s. Did a DFU restore yesterday with no backup restore. Manually insatlled apps from App Store and still it sucks. Restore to iOS 10.0.2. Very unhappy.

That's exactly what I'm getting. Did you check your battery using coconut battery?
 
Please don't report battery issues earlier than a few days after installing an update. It's irrelevant at that stage.
