I used the Galaxy Charging Current app to look at my S5 with the OEM charging cover. Charging current average is 1200 mA wired, 640mA on Qi with the "lilysagu" chargers we use at home and work:
http://www.ebay.com/itm/26150291499...49&var=560382297404&ssPageName=STRK:MEBIDX:IT
and with the Sammy OEM Qi charger.
Operating status conditions of the S5 were the same for both - basically I measured the charging current on the Qi stand, then unplugged the power supply from the stand and plugged the power cord directly into the S5.
My wife's S5 uses the "fone salesman SlimPWRcard" add-on receiver, and her charging current with that receiver is about the same as my Sammy OEM Qi back. To make a direct comparison would require that I set both S5s to be running exactly the same apps, network, etc. and frankly that's more trouble than it's worth considering the small difference in measured current between the two.
So it appears that Qi charging takes about twice as long as wired charging. For my wife and me (we both have an S5) that's not an issue since the S5 battery life is more than adequate for all day use so we just drop the units on the charging stands when we go to bed. We love Qi charging - I'm posting this for the heavy users, for whom faster charging may be important.

You should be able to get 1800 mA out of the stock charger... With Ktoonsez kernel, I actually get up to 2200 mA. Are you using the OEM charger/cable?

You're right - when I use the Sammy charger & cable I do get 18oo mA.
Note however that a replacement USB3 port cover is US$11 on Amazon.

just spotted this
http://www.qiwireless.com/toshiba-starting-production-faster-wireless-charging-chip/
Wireless charging at wired speeds. I am avoiding wireless charging due to the slow speed of it but if this thing works I wont need to avoid it anymore.
When available, would this work with an S5? It says it uses Qi as "its base for wireless charging". This is unclear to me, does this mean it is a Qi charger or that it simply uses some Qi stuff and then goes beyond it to provide the extra power, so it isnt actually Qi at all (if Qi is a standard then I assume this new thing doesn't confirm to that standard and so it isnt Qi, in which case it wont work with existing Qi devices?)?
What I would also like to know is does this new chip need to be in the phone itself, or would the chip they talk about be inside the back cover, or in the charging pad? Obviously if the phone itself needs to support this specific chip then its not going to be any good for s5 users, but if it is independent of anything in the phone and work would on an s5 then it may be worth waiting for it, it is apparently already in mass production so should be around soon I guess.
Based on the (albeit limited) numbers they provide in the article, it appears this is still a low-power Qi spec device like the ones we have today, which have a maximum output of 5W.
The wireless charging integrated chip will be following the Qi wireless charging standard as its base for wireless charging, which is great since this is currently the most used wireless charging standard for current devices. Along with this, the chip will be able to have a maximum output of 5 watts, which is comparable to a wired charger.

Unfortunately they say nothing about how this would differ from your run of the mill ebay Qi solution.
Mathematically (which admittedly is not my forte), if we assume "Wired" charging rate is 1800mA, 5W @ 5V requires 9W to hit 1800ma, which is outside the low-power Qi spec.
Then it is even more confusing as the entire article seems to be suggesting that it will charge at the same rates as wired chargers and much faster than current Qi systems.
Standard wired charging rate is 1amp, at 5v that is 5w
So if the new induction/wireless charger can supply 5w that means it will supply 1amp which is the same as wired
These will be roughly the same charging speeds
by the way, if you look at the charger your phone came with it clearly says "5.3V and 2A" so no the wireless charging will not compare to the conventional wired charging using your stock charger

This is correct, sorry should of also made my post more clear
5v 1amp is most common on many devices now and the qi statement relates to many devices so technically what they say is right BUT now some devices including the S5 do use slightly higher voltages and some draw more current now meaning wireless charging on our device will not be as good as wired BUT for most people that simply charge overnight it will make no difference
Those that charge overnight wireless charging will be perfect
Those that excessively use their phone and need as much charge as possible in short periods/quick charges throughout the day etc should use wired charging
So my friend borrowed me his charger from his phone, which is a galaxy edge. It said it was charging rapidly and omg it sure did. It was super fast. Does the N5 support any kind of fast charge? Will this break my battert?
Also attaching screenshot
Thx,
Dan
how many output amps was that charger?
I tried charger that came with Galaxy S6, which has output of 5V - 2A, and 9V - 1.7A when recognizes fast charging device. It charges my N5 from 15% to 100% in about one hour, but on lockscreen, it only says "Charging", and charges it really fast, without heating the phone, which then seems to be pretty much safe.
@tampitzel If the phone doesn't get hot to touch on the back while not used when charging (warm is ok), then it probably is safe to use.
If the screen starts to flicker, or doesn't respond well to touches (eg. while typing), that means that charger is giving too much voltage and that's bad for phone. But that mostly happens with cheap non-original chargers.
Cheers!

I will check, I didn't look to be honest, I was just baffled by fast charging
Nexus 5's OEM Charger (by LG) is rated at 1 amp - whereas the Blackberry OEM travel charger (folding plugs) is rated at 1.8 amp - been using it for a year - and, it fast charge the battery typically in 1 to 2 hours (even when it's down to 25% to 40% on heavy use for the day) with its extra long micro-usb cable. http://www.amazon.com/BlackBerry-Pr...1449956341&sr=8-6&keywords=blackberry+charger
No need for custom rom or other "tweaks" - for in-car use, a 2-amp mobile charger with a high quality micro-usb cable is the "key".
Good and beefy cable makes an improvement more than you would ever imagine!
The stock charger is rated for 1.2A not 1A.
The Nexus 5 doesn't have any kind of official fast charging. However it will allow up to a 1.8A charge rate. Plug in a 2.4A charger it won't go any higher than 1.8A. Its what the TI power circuitry is rated for.
I find it a bit strange that through coincidence that the Blackberry folding blade charger is the best (I would say perfect) charger for the N5. It was cheap and plentiful as well as high quality.
I picked up a cheap ebay Qi charging pad that is listed as 1000mah and it just arrived today. I was under the impression that Qi charging is 70% as efficient as wired and assumed that I would at best be charging at 700mah.... but my phone is charging at 1900mah which is the max I've ever gotten wired. Just using a standard cheap charging pad also. How is this possible (also, not an April fools post - but I'm sure I read that they aren't as efficient as wired)
I guess I figured it out. My phone has a 2600mah battery and the charger is 73% efficient, and the efficiency is based on the battery rather than its maximum charging rate of 1900. 73% of 2600 is also 1900 so that's what I'm getting. The thing that surprises me is that I'm getting it pretty much consistently, whereas with a cable it fluctuates all over the place and I very rarely get a 1900ma charge that way. So I guess wireless can be faster than wired, depending on the phone and the charger.
Also, I can't understand how my charger, which is listed as having an output of 1000ma, is able to generate 1900ma. Something just isn't adding up
It seems that the phone just reports incorrectly during wireless charging. It took 90 minutes to charge from 50-100%, so that's in line with the 1000mA I expected
Good day. I have a g930L. I'm using an old original galaxy s4 charger with a 2A output. I've tried monitoring the current with ampere pro and noticed that charging goes up to 1700mah but for only a very short time like a couple of seconds and reduce down to 1A. It stays for 1000A until it fully charges. I used also ipad charger 10W and still same behavior. I also tried different cables but only a maximum ofless than 1800. Buying a wireless fast charging will make the phone reach 2A?

You can use my app to monitor charging more easily
https://forum.xda-developers.com/android/apps-games/charge-monitor-t3555496?nocache=1&styleid=22
To answer your question, wireless charging produces a bit more heat so I don't think it'll charge more rapidly. If you want to charge faster make sure fast changing is on.

How about buying an official S7 charger?
Doesn't sound like rocket science that old S4 chargers and chargers designed for completely different devices are not charging the S7 the way it was intended
Hey guys,
So I got this Samsung wireless charger that is supposedly 'original' from Aliexpress.
There's actually a fan inside and it does say that it's fast wirelessly charging on the phone. However it is not that fast - 15% in 40 minutes. What speeds do you get with your wireless chargers? I'm using the original wall adapter from Samsung (9V 1.67A one).

If it cost less than from the samsung store then its not original, it does take 4 hours to charge the phone with the cheap wireless charger.
Of the ones I've used even with my S5, I found the cable and power supply are critical. Lastly the placement on the charger. All of mine have come from an Aliexpress seller. I can't tell you exact times but I know they charge as fast as the phone will allow before overheating. Not to say some sources aren't bad. Just my luck has been good. I even converted some of my S5 vehicle charge pads, simply by adjusting the charge center, and have continued to use them. Anyway, try different cables and usb supplies. if the phone doesn't get warm or better it isn't charging fast.
