    i have had my iPhone 6S Plus for over a year now but just yesterday the 20% battery warning appeared and then my iPhone 6S Plus automatically shuts down. When I try and switch it back on I get the empty battery icon with black background. Anyway, when I connect my iPhone to the charger it displays 14% on the battery. Something is not right here. My iPhone shouldn't shut down with still 20% battery left.

    I went onto the Apple site and typed in my serial number to see if my iPhone was one of the affected units with the defective battery but according to Apple my iPhone isn't one of the defective units so I cannot get a free battery replacement.

    This totally sucks as I have only had my iPhone 6S Plus since November 2015. I am certainly not willing to splash out nearly £1000 on another damn iPhone. Please advise.

    It Doesn't necessarily mean you need a new iPhone. I would make an appointment with Apple and have them conduct a battery test. Sounds like your battery might be in need of replacement or it's more than halfway through its cycle.

    I have only had my iPhone for over a year so surely the battery doesn't need replacing. If this is the case then it is unacceptable and shame on Apple. The nearest Apple Store in nearly 100 miles away.

    But at least the first beta does not fix this draining issue. I doubt it.

    Not every iPhone is perfect and some will have issues over others.

    The only way to know for sure is have Apple complete a diagnostic on the battery. It might inconvenience you the commute, but it might save you from a purchasing a new iPhone if need be. Unless you consider third party repair options to diagnose the issue.

    I would drive 100 miles to save buying a new iPhone.

    Our 6S+ does the same thing if it is out in the cold. We took it to the Apple Store and they said there is nothing wrong with the battery LOL The "Genius" bar is generally useless in my experience. They are rarely able to help, and will rarely even admit there is anything wrong.

    +1 for wacky's situation. There are whole threads about the battery issue in relation to the cold.

    What happens is that over time the battery becomes more susceptible to the cold. A few weeks ago, I took a fully charged 6S+ out in my back pocket while I shoveled the snow. In a period of about 30 minutes it shut down and gave me the plug in cable screen. When I plugged it in it popped up to 30%.

    So technically, there is nothing wrong. Diagnostics show that my battery is still over 90% of its original capacity, and in normal temperature conditions it performs like it always has.

    However, if you get a new phone and subject it to the cold, you won't get the huge drop off.

    I had this exact problem on my wife's 6s+. Shut down at 17% and wouldn't turn on until I started charging it. When it came on immediately after plugging it in it showed 34% battery. Brought it to Apple and they ran a test on the battery, which came back as being fine, so they refused me a new battery. They blamed it on a problem on the circuit board, and since no AppleCare+ I had to spend $329 for an out of warranty replacement. Come to find out it could be an issue with iOS 10.X. So I probably spent nearly $350 for no reason. BTW, I'm in South Florida. Doesn't get cold here.
