    Last week I got my iPhone XS, and decided to check charging rates.
    First I used the default 5W charger, that the phone came with... the day after I used a 30W adapter (incl. a USB-C to Lightning cable).

    Here are my findings;

    [ Default 5W charging ]

    20% charged after 30 min
    38% charged after 1 hour
    54% charged after 1,5 hours
    82% charged after 2 hours
    94% charged after 2,5 hours
    Fully charged after 3 hours
    -------
    Total time needed: 3 hours

    [ Fast 30W charging ]

    53% charged after 30 min
    81% charged after 1 hour
    95% charged after 1,5 hours
    Fully charged after 2 hours
    -------
    Total time needed: 2 hours

    • As you can see, there's 'only' a 1 hour advantage over the default 5W adapter, the biggest gain is made in the first 30 min.

    Now I'm wondering, would it make any sense to get an even faster charger in the near future, in order to have more time advantage?
    (for example get a 61W, or even a 81W adapter)

    Does anyone know what the limit is, that the XS can take?
    (would be kinda useless to get a 81W adapter, only to find out the XS has a limit of 30W)

    With the capacity that iPhones have , I think fast charging should be much faster than what Android phones have, but currently even Android phones with 4000mAh charge faster than 2 hours.

    Interesting, so what happens if you start fast charging at 50% ? this is a circumstance familiar to me, where I know 50% will not carry me through to my return to my charger, and I need to leave soon.

    Thanks for the review. I personally like the fast charging. Yes, an hour for fully charged makes a difference and so does the other levels.

    I enjoy fast charging as well. Especially when charging from 20-80%.

    It's designed to charge faster when the battery is lower then slows down as it gets full. I remember last year seeing a graph of 5W vs 12W vs fast charge vs 5 and 7.5W wireless charging and the 12W iPad charger was nearly as fast to the 90%+ range as the fast charge setup. The difference was in that first 20-30 minutes or so.

    My personal advice is not to go faster than an iPad charger. Fast charging is ruining your battery over a long time.

    Yep that's it! I don't normally need the "X amount of charge in 20-30 minutes" benefit of a fast charge so that article was what convinced me not to spend the extra money on the hardware since I already have a bunch of 12W iPad chargers laying around.

    I agree. I think staying between 7.5W and 12W fast charging is your best bet...and from doing research choose a wireless fast charger with Qi technology which is what Apple uses in the newer wireless charging iPhones.

    Yep the first 30 mins is noticeable on my iPhone XS Max. It is nice for when I really need it otherwise I don't care. I use my USB-C brick w/ USB-C to lightning cable really only at work. At home I just use the iPad brick.

    I don't think its even worth the money. Plus it damages the battery by creating more heat. Unless you absolutely need it its not worth it.

    I'm pretty sure it's 30W because when you read the description for each adapter on Apple's site they stop mentioning the iPhone compatibility after the 30W charger.

    By the time I notice anything bad with the battery I would have upgraded.

    I pretty much just use my 10W fast wireless chargers for topping off. I still plug in for overnight charging until I get a wireless charging stand that sits up. I enjoy rolling over in bed and looking at my screen.
