    Picked up the Apple 29W USB-C charger and an Apple 2M USB-C to Lightning cable to take advantage of fast-charging on my iPhone 8+.

    Upon plugging it in - it chimes/vibrates and shows the charging animation. Then, it goes away/off for a second - before resuming charging for good.

    Is this an intended feature of fast-charging? Or is something wrong.

    I’ve tried restarting the iPhone, different charging outlets, etc.

    Thanks!

    What do you mean " it goes away/off for a second" ?

    Poor wording I guess.

    It literally stops charging for two seconds before it resumes charging for good.

    Not sure if that is normal or not. My wireless charger and plugging in my regular lightning cable produces the exact same behavior. I do not have any “fast charger” devices so maybe that is the difference

    Yes it works. I have the same set up. 29W and USB C to lightning cable. Charges pretty fast.

    Fast charge is pretty cool. Just need a cable since I already have the plug. Curious about the issue op is having.

    Apple has a doc on it somewhere on the website - if explicitly stated on the website, my assumption is that it’s fine.

    Nobody has actually answered my question yet..

    Aside from Newton - can anyone else confirm or deny that this is the intended behavior of the fast charging tech?

    30/60/90 minutes = 53%/81%/94% with this setup from completely dead.
    100% after 2h6min on 8+ vs 3h15min using the out of the box charger.
