    Hi everyone -

    I've had my iPhone 6 since it came out and all of a sudden the battery started showing 100% at all times and it claims to be charging in the evenings, but the phone will suddenly shut off and briefly say the battery needs to be plugged in. As soon as I do, the battery indicator goes to 100% once again.

    I took the phone to the Apple Store today and their diagnostics claim the battery has 0% wear level after 3 years -- which seems absolutely impossible. They did some firmware restore and wiped the phone claiming it was a software issue. After an iCloud restore of my data without the phone being plugged in, I'm back to 100% on the battery.

    As the phone is out of warranty, I'm trying to figure out whether I should try replacing the battery myself or if it's a bigger issue. I'd like to give this phone to a family member once the 8 comes out and I'd like to be able to keep using it in the meantime without it randomly shutting down.

    Anyone else have this issue and find a fix?

    Update:

    Phone died again suddenly after my visit to the Apple Store. I was able to get a walk-in appt to another Apple Store yesterday evening. Their diagnostics again showed there was 0% wear on the battery which this Genius agreed made zero sense. They made me the offer to replace the battery and if that didn't fix it to replace my phone and apply the cost of the battery to the replacement.

    A battery replacement seems to have completely fixed the problem. Everyone at the store was surprised to see the symptoms I was seeing. I'm glad this store had a Genius who understood what the diagnostics were showing didn't make sense and was willing to change the battery for me.

    Issue you mentioned was related to chip on battery. Sometimes poor quality replacement batteries also have damaged battery indicator.
