    Hi, I went to an apple store to replace the battery of my iPhone 6s+ using the battery replacement discount program. The genius tested my phone and it failed the battery test. How come it failed so soon? Is that the reason Apple offers the replacement program?

    What exactly are we talking about when it comes to "so soon"?

    What's "so soon"? If you purchased your 6s+ around when it launched it's 3 years old, and "failure" usually just means that it's below 80% capacity. That's not unusual.

    I see. Why below 80% capacity is considered to be a failure? Is 79% also a failure?

    I mean is it normal that battery fails the test in about 3 years and require a replacement?

    It's not unusual for a battery to be fairly worn out after 3 years (sometimes even less than that).

    It's not the Days / Months / years that mater. It's the number of charge cycles that matter, also the amount of heat your phone / battery was subject to doing use / charging. These will all impact the health and condition of the battery.

    Mine is on 85% but as soon as you unplug from charging you can virtually watch it go down. Once it hits 20% you’ve had it. My mother still uses my 5s which is much better.

    I feel the batteries in these phones were just bad. I had a 6S and a 6S+ and both needed new batteries. The 6S+ was reporting 80% in coconut battery. Apple said the battery was fine and refused to replace it even though for me it would go from 75% -15% in 5 hours with no usage. I ended up taking the phone to a local place to have the battery replaced. A few months later, Apple announced their replacement deal for $29.

    When I got my phone back, the battery life was 12%. I asked genious why it was not 100%, she said that they had no time to charge it. Shouldn't brand new batteries be fully charged? Did they give me a refurbrished one?

    They wouldn't be fully charged as storing them is best at somewhere around 50% or a little more.

    So I guess 6s+ users got poor battery and Apple replaced it at lower cost to compensate for their mistake?

    A battery being fairly worn out after 3 years isn't all that unusual.

    did i understand it correctly. The capacity was around 80% and you wanted to replace it but they refused to replace the battery. were you asking it for free or wanted to pay the service?

    They're test showed the battery capacity was still good so they would not replace the battery. I didn't ask for them to do it for free or a fee, it never got to that one their test showed the battery passed.
