    As with pretty much any update, some people experience some issues here and there, while most don't appear to be.

    I have a 6s and have no performance or battery issues with the non-beta version of IOS 10.

    I got rid of my iPhone 6s Plus, but the battery life or percentage at the top was a joke after updating. One time I unlocked the phone and it went from 15% to 1%. The phone would stay on 1% for like 4 hours though so I assumed it was ios 10.2.1.

    I also cannot connect to any bluetooth items anymore, even after buying an iPhone 7 Plus.

    I had battery issues galore until I took it to apple and they replaced it under warranty. The phone I have now is basically fine, still noticeably less battery life than iOS 9 but much better than the old phone.

    My iPhone 6 battery is beginning to malfunction a bit, I'm pretty sure. I've had the phone for 26 months and it's still on iOS 9.

    This is what i am still afraid of. Guess i'm gonna be stuck on ios 9 forever, really who needs less battery life?

    I was planning to upgrade to ios 10.3 but still i'm doubtful.

    I wonder about the people buying an iphone 6s this year with ios 10...the battery life would be decent? mmm

    Hi there , i just made an account here for ios 10.2.1 battery problems on my iphone 6 , i got this phone for just 4 months(brand new ) . On ios 10.1 i had no problems battery life was very good( better than my samsung s4) , but after 10.2.1 its a wreck ( ios 10.3 beta 4-5 too) . Last night i observed an abnormal usage , battery went from 65% to 25% in the morning and my phone usage shown in battery was 5,32 hours ( i used it aproximately 1.9 hours ) .

    Can i somehow downgrade to an older version like 10.1 , 9 and still sign in to icloud ? In my Country( Romania) we dont have apple shops only resellers . Battery wear appear to be 0.6% in apps(its only 4 months used phone )
    Thanks .

    No. It's impossible to downgrade below 10.2.1. Apple doesn't sign any firmwares below that one beside the 10.3 betas at the moment.

    My first 6S+ bought Feb 2016 was so bad I sold it. Came with original 9.1 I guess. Just bought a refurbished of same from Apple and night and day.

    I think some units have had battery issue from during production and contamination (nothing like Note7, too big and shorting out bug though!)

    Id think by now, 5 months since iPhone 7 Plus shipped, that be okay.
