Today, I tried coconut battery on my iPhone 6 plus and it showed 171 cycles but only a 75.6% capacity left on the phone. Is this normal for the number of cycles? Does anyone else have experience with their iPhone on coconut battery? The Applecare customer service reviewed my battery diagnostic files and they said there were no issues with my battery but I thought under 80% capacity isn't good. I got my phone in November 2014. Thanks.
