    Hello guys! I got a problem. I can't decide what wireless charger would be better for charging my iPhone X considering the fact that the future update iOS 11.2 will unlock the 7.5V charging capabilities...In my country I can only find Samsung Wireless Chargers...
    Is this one good? http://www.cel.ro/incarcatoare-tele...samsung-galaxy-s8-s8-pluss-negru-pNSM2NzUu-l/

    Or would you recommend me anything else from samsung?

    I have the same question and haven't bought the Samsung Convertible Wireless Charger yet because I don't know if it'll charge at 7,5W specifically.

    Yes, I know it has a 9W output, but I'm not sure if it'll charge at 7.5W.

    I’m starting to think this as well. I’m not sure if a 5-10w charger will charge at 7.5 watts. I was thinking it should try to push from 5-10 until the device caps, which would be 7.5 for us. Not sure if it works that way though. Can anyone confirm?

    I already have it. How can I tell if my wireless is charging at 5 or 7.5? I got the public beta, anyone can download it.

    Curious about this as well. I was thinking of getting a Samsung Fast Charger but want to ensure it will actually fast charge.

    If you have a Mac, download coconutBattery and enable wifi sync through iTunes.

    Then, open coconutBattery, enable the Plus trial (Menu Bar preferences), draw your iPhone battery to something like 30% and put it on the wireless charger. coconutBattery will start showing the charging rate of your iPhone (it's on the bottom of coconutBattery window, where's written "Charging with").

    It's not in Mac App Store.

    http://www.coconut-flavour.com/coconutbattery/

    It's from a signed developer, so macOS will run it without any issue.

    Got it! Looks like my phone is only charging at 2.58w at highest. I’m running iOS 11.2 beta 4 with a 10w wireless charger plugged into a quality qc 3.0 port. Any ideas? It’s not even charging close to the 5w limit it has before the update.

    What's your wireless charger?

    How many percent was your battery at when coconutBattery measured those 2.58W?

    Also, it's important to note that the app won't show 7.5W charging rate because it needs to subtract the amount of energy the phone is consuming while it's charging.

    My wireless charger is
    Pictek Fast Wireless Charger, QI Wireless Charging Pad (Ultra Slim) (Sleep-Friendly) For iPhone 8,iphone 8 Plus,iPhone X,Samsung Galaxy Note5, S7,S7 Edge, S6 Edge Plus,S8,S8 Plus https://www.amazon.com/dp/B01MSRQ4TG?ref=yo_pop_ma_swf

    It’s rated at 10w. However does that mean it would stop and charge at 7.5w or does that mean all these 5w and 10w combined chargers only charge at either 5 or 10? I was thinking these chargers that charge up to 10w would max the power of the device up to 10w.

    Also my phone battery was around 70%-80% I believe at the time I did this test.

    That's the reason why it was charging at only 2.58W. The closer the battery is to 100%, the slower is the charging rate.

    Draw your iPhone battery to ~30% and check coconutBattery again.

    Ok I used my phone down to 22% today and tried it again.So I have a 70w charger with 10 ports, 8 ports max of 2.4 amps and 2 ports Qualcomm 3.0 quick charge ports. Also to mention only one device plugged in during this test, all other ports not being used.

    I tested the 2.4 amp port using the wireless charger and got a speed of 3.49w at highest. Using the same 2.4 amp port I plugged in the device old fashion way and got a charging speed of 7.07w.

    I tried both again on the Qualcomm 3.0 quick charging port. With the wireless charger I got less at 2.8w. Also with the regular plug in I got less at somewhere around 6w. So it seems overall the “quick charge” ports are worst for my device then the regular 2.4 amp ports.

    What do Qualcomm 3.0 quick charge ports put out anyway?

    I have the new Samsung Wireless fast charger and it charges the iPHone X for me only when put flat down. It doesn't charge when I have the phone standing up. Strange. I have another wireless vertical charger and it charges the iPHone X fine when standing up.

    I just found a good wireless fast charger for the iPhone X.
