    Theres been a ton of rumors about wireless charging for the new iPhone but one that I haven't heard much of is fast charging capability. Has there been any rumblings of this I might have missed? Do you think they'll add it? Without a iPad charging brick, the 7+ charges laughably slow and it'd be up there with the OLED screen as biggest improvements I'd want.

    They make faster charging for the 7+, as you mentioned, get an iPad brick or anything faster than 5W. Its physically impossible to charge the iPhone faster without a more powerful charger. 5W can only push so much power.

    I have an iPad charging brick and use it every time because it's insane how slow the 7+ charges with the included brick. But my question was, will they make strides to make it even faster than it is now. It still takes over 90 mins even with the iPad charger.

    I honestly can't say it has taken over 90 minutes using a 12W charger with my 7 Plus. I typically plug it in around 20% and about an hour later (if untouched) its pushing 95%. So maybe 90 minutes from completely dead.

    Samsung S6 charges from 5%->100% in 72 minutes with the quick charger. So a little bit faster. But whats really important is how quick charge is 'enabled' (lack of better terms). Fast charging = heat, heat = degraded battery life.

    I would love to see Apple adopt USB-PD standards for charging devices as that's where the industry is heading but seeing as it's Apple, they'll come up with something proprietary.

    I'd say they absolutely need to address it with the iPhone Edition. What Samsung and the Pixel have in place is far ahead. Now, on the flip side, neither of those devices can touch the iPhone 7+ in terms of battery life so it's about an even trade off.

    But Theresa nothing worse than when you're low on juice and it takes forever to charge.

    You do know that quick charging destroys your battery right? All it would do is cause a bunch of idiots to start complaining that their battery's are ruined and start a lawsuit.

    I don't know if there's actual proof of this. I could be wrong though.

    I stated above why quick charging has negative consequences. Quick charging = heat. Heat degrades battery. That's 100% proven. iPad charger provides a faster charge but does not increase heat. I would not use anything more "powerful" than an iPad charger.

    I understand that but is there actual data that proves battery degradation? Not saying there's not but I'm curious if this is actually proven.

    Yes it has been proven. There are hundreds if not thousands of articles showing the correlation. Even Apple tells you not to operate your device at certain temperatures and has a temperature shutdown point to prevent damage to the battery and device. Even when you do a battery diagnostic with AppleCare it checks the temperature sensors of the battery to see if they have been tripped.

    I doubt there will be any faster charging hardware updates. Just use and iPad charger and it's plenty fast.
    And if wireless charging is included it will be slower charging.

    This. I don't understand the obsession with wireless charging. It's slow and causes heat. My 7Plus charges faster from 5%->100% than my Series 0 Apple Watch from 5%->100%. No thanks.

    Samsung's Galaxy S7 charges pretty quickly using wireless charging so the tech is there, the only way Apple would have wireless charging on the iPhone is if they went back to using a glass back, if the iPhone 8 has a glass back then it's more likely may have wireless charging to.

    I've always been abit suspicious about quick charging myself, my Nexus 6P had it & if i ran the battery right down it would get quite warm when charging from 20% to 100%, and before i sold it the battery within a year degraded quite alot, don't know if this was down to quick charging or Google & Huawei cheaping out on the battery.

    I do personally think quick charging could have an impact on the battery than what standard changing would do, this maybe the reason Apple still hasn't used it in any iPhone's to date even though quick charging been around for a few years now.

    Personally, wireless charging will certainly have its limitations and I see it as a secondary option, not a primary, being its still expanding technology. Wired charging is the most convenient form of charging available for obvious reasons. I still prefer a lightning cable and charging my device this way, Even when Apple releases wireless charging, it's still a situation where you have to have the iPhone docked on a certain placement for it to charge. Ultimately, it comes down to preference of what the user wants.

    I am with you on this. My 7+ gets through the day with ease and letting it charge while sleeping. Wireless would be a bit more easy but plugging it in is a non-issue for me. As far as speed, could care less.

    What do you consider charging pretty quick using wireless charging?
    Its not as fast as regular charging and causes added heat.

    USB-PD is a must! The MacBook already supports it, so there's hope. Plus there was a rumor a month or so ago about Apple switching to USB-C, which turns out most likely to mean that they'll keep the Lightning connector on the iPhone but just change the other end of the cable from USB-A to USB-C.

    This would be awesome if they combined it with USB-PD; the current 12W is ok, and reasonably quick - but if they went with 30W (20V/1.5A), that would be excellent. Could always give it the full 30W up to about 80% charge, then slow it down to keep heat in check.

    Frankly, I'd be happy if they ditched Lightning completely and just went with USB-C :)

    Have you not seen OnePlus' implementation with Dash charging? All the heat is in the brick and keeps the phone/battery cool.

    And yet it's not that much faster than a 7 Plus with an iPad charger. That's 85% in 60 minutes. Last night my iPhone 7 Plus went from 9% to 77% in 60 minutes. To each their own, but I have zero problem with the current set up.

    Longer battery life would be better than faster charging.
