    Hi.

    I have my iPhone7 for almost 2 years. From the first day I'm not satisfied with the battery life. Now my battery has 84% of its original capacity. I still have 2 months of warranty and I'm not going to buy new iPhone in next months.

    When is the best time for me to replace the battery?



    ps. Besides the battery myiPhone works perfectly and I'm not sure if new battery will change anything for me. It will just cost the money and will have to be a little bit worry about possible problems after battery replacement like here: https://forums.macrumors.com/threads/iphone-7-battery-replacement-gone-bad.2134386/

    Mines new since June 2017 and is at 87% according to battery app. I’m not at the two year mark yet and do wonder what will happen as well! It’s dramatically dropped in % since I last looked a month ago! It was at 91% at that point.

    I was under the impression Apple issued the cheaper replacement at 80% capacity. I could be wrong tho.

    Now. Prices for battery replacements will increase in December.

    Do it now. I have a backup 6S that’s showing 89% and I’m getting it replace before the end of the month

    Are you calibrating the battery every month and after an iOS upgrade? From what I've read, we should be doing that.

    The battery doesn't really need to be calibrated that often. Only when the gauge reads the battery inaccurately. This is also recommended after battery replacement.

    Can be done before that too if battery performance isn't all that good, especially this year with the cheaper battery replacement program.
