How about a bigger battery instead?
I have been on the bigger battery train for a while but it may not matter too much once Apple releases a real wireless charging solution. All your devices will charge or top off just by being in the room.
Got a tip for us?

Sketchy Rumor Suggests iPhone 7 Will Feature Faster Charging Speeds

My bad, despite reading it and even typing it myself, I was treating that W in that 12 W as V for some reason.
As I said in a previous comment, look at the company Energous. They specialize in long range wireless charging and have been rumored to be working with Apple. Imagine you will be able to use your device and walk around your room/house as it charges. This would go for any Macs, iPhones, iPads, Apple Watches, etc. Way more exciting then setting your phone on a mat to charge.
The fact that faster charging is rumored, highly suggests that the i7 range battery life is rubbish.
I saw that.
One report says it'll be ready and shipping as soon as 2026. That's warp speed for Apple...
That's why iOS charges rapidly to 80% and trickle charges from 80%-100%

(I suppose you can greatly reduce battery life by only charging to 80% everytime and draining from there)
This behavior isn't limited to iOS devices. This charging behavior applies to literally every single lithium powered device that exists from your smart phone, to your laptop to a Tesla
And only charging to 80% will actually dramatically increase your battery life. Lithium batters do not like being charged to 100% and hate being kept there for any extended period of time. The "fast charging" isn't so fast that it hurts the battery in any appreciable way.
Battery cycles don't really depend on how fast the battery is charged, but for how long, in the sense of how full the battery gets. That said, faster charging can create more heat, and more heat, in general, can have more of a negative effect on battery capacity/life.
Seriously, what is so great about it, and I ask in all honesty? Sure you don't have to plug your phone in (which really I've never felt to be an issue), but it renders it pretty impractical to use while it charges. Often I get to bed at night, I plug my phone in as its on its last few % and then continue to use it, wireless charging would mean it just has to be placed down to charge. I just think they solve a problem that wasn't there to begin with. But that is just my opinion, maybe I'd think differently, though I know my friends ceased using theirs with the Samsung once the novelty wore off.
And please don't start on the wireless charging throughout the home, I agree that would be great but it's years/decades away.
Oh wow. Fast charging.
If true, welcome to 2014 iPhone 7.
I've been "fast charging" iPhones and iPods for years, well before 2014. Just use a more powerful iPad charger rather than the weaker one bundled with the phone.
Simple convenience? Kind of like what's so great about car keyfobs or something else along those lines?

Yeah, except that wasn't the case considering those devices couldn't draw any more power from even the more powerful adapters than they could from the bundled (weaker) ones.
interesting. this must be a new thing then. b/c in the past they've not allowed iPhone to draw more than 5w.
when I test my 6s using 5w vs 12w, there's no difference. looks like I have a reason to buy a kill-a-watt now.
thanks for the links. mods: disregard my earlier post. outdated info.
Err... it wants to draw 2 Amps to fast charge but the charger supplies only 1A so it doesn't charge as fast (but might extend the life of the battery a bit). The actual charger is in the phone, the thing you plug into mains is just a 5V power supply. You do need "IQ" charging to enable the fast charge times though, I don't know how that works exactly, but it charges at low currents first and the phone can request "gimme more, I can take it" and the charger ramps out the output (more voltage would actually be smart).
seems like the 6 and above models are being allowed to draw more. I stand corrected.
although in my testing, the 6s seems to be no different charging via 5w vs 12w.
I only does when you overdo it, i.e. battery gets warm while charging. Batteries are rated for certain charge currents and discharge currents (typically you can discharge them 10 times as fast as you can charge them). If you do more, the friction of current going through heats things up and it wears out. On a brand new battery, there's usually some chemicals in the battery to make it last longer in storage and the performance of the battery is restricted until you break it in (charge and discharge at lower speeds about 5 times), which they apparently do before putting them in phones.
The best thing you can do to keep a long battery life is to keep it around 50% and not getting it too hot. Leaving charged at 100% in a hot car: bad. Leaving it at 0% for months: bad. Letting it drain to 40% over night and fast-charging it in the air-conditioned car on the way to work: good. Those external batteries are great, price went way up since Pokemon Go though.
Well, it's hasn't always been like that, but since the iPhone 6 days.interesting. this must be a new thing then. b/c in the past they've not allowed iPhone to draw more than 5w.
when I test my 6s using 5w vs 12w, there's no difference. looks like I have a reason to buy a kill-a-watt now.

it's a lot more complicated. the charger itself is in fact the adapter. the iPhone just has a controller on boards that works in conjunction with the adapter controller to determine correct power.
fast charge first, then trickle charge to capacity.
more like the opposite if anything. if the battery has a higher capacity than previous models it will take longer to charge to 100% if charging at the same rate as previous models. introduce fast charging at the same time as higher battery capacity solves this perceived problem.
Given this rumor, I think they'll give it a slightly longer battery since Apple will then be able to use the opportunity to present it as "Longer battery life: Faster to charge". That combo has WAY more impact than "Faster to charge" alone. It would sound so good that it could become a prime candidate to even upgrade for some.
Fast charging? Welcome to 2014. Oppo had it with VOOC.
Wireless charging? Welcome to 2012. Or before that with the Palm Pre. Nice one, Matias Duarte.
Wow fast charging. I had an Ericsson phone in around 1992, which charged from dead empty in 15 minutes. Mind you that was the only good thing about the phone, the rest was c**p. You also had to have this charger the size of a brick.
