Nexus 5 doesn't take advantage of "Quick Charge"?

People are saying the phone takes 1:50-2:00 hours to charge with a 2300 mah , the LG G2 which also has a snapdragon 800 takes around 1:30 to charge with a considerably larger 3000 mah battery , the nexus 5 comes with a 1.2A charger ( the G2 comes with 1.8A charger) so maybe that's the reason, but does it support quick charge at all? Google/LG just decided to save some cents and threw a cheaper charger on the box? If I buy a 2.0A charger would I be able to use it and would the phone charge noticeably faster?

Most probably Not.
I think the Situation is a different too. LG uses its newly invented battery Type with enhanced Features. including massively improved recharging cycles.
Goggle does Not. and its known to batteries. the faster you load the quicker they die. no matter what they say. even eneloops are prooven to die much quicker when generally loaded at Max speed.
I have a Sony Tablet z charger with 1500mAh loading and a Asus me 301t loader with 2000mAh loading speed.
After some cycles I'll try them to See any difference but im sure there wont be.
DONT USE ANY FAST CHARGERS WITHIN THE FIRST (Minimum THREE) CHARGES.
Not to Do so is said to seriously harm any battery.

If a quick charger could harm the battery it could also charge the phone quicker which it won't because the phone regulates the battery charging process and doesn't really care if the charger is able to output >1.2A . It would make a difference if you charge your phone on a <1.2A charger of course.
If it wouldn't work that way you couldn't charge a friends 3 year old Smartphone on your wall charger

My old HTC Desire S 1450mah battery used to take 2.5-3 hours to charge. My N5 takes around 2 hours.

That is why I said it most probably won´t make any difference too.
Usually phones do limit the charging power. I don´t know any device that does not. But I would be carefull with this chinese stuff
This is why my Galaxy Note wont charge any faster than with its original charger at 1000mah.
It is even possible that the Nexus only loads at 1000mah and the loader hast a little backup. But not very likely either.
When it comes to my Note...when I remove the battery there is a sticker where it is stated what is used:
5VA 1000mah.
So we can´t do that with our nexus
Grab your (Handbuch) User manual and look up if there is any information about it.
The quick charger thing...correct...I may have gone little overboard with my warning thinking myself it wont make a difference.
But you really should keep that in mind for your mignons ect.

Quick charge is built into the Snapdragon 800 processor. Qualcomm announces it like a feature but no manufacturer uses it, probably because the N5 is only the third phone to come packing the S800. It'll be up to Qualcomm to release a patch (like they said they would) so that we can utilize the quick charge feature.

Would suck if they have not included quick charge...

I refer to my (non-scientific) test conducted using the G2, S4 and N5 for charging performance. They're all pretty much the same, but the G2 was the fastest to charge.

I let all the phones run down overnight to 0% using the battery drain app from Play store. I then used the charger and cable that came with each device, here are the results - interesting test.
N5 - 2,300mah battery, 5.6V / 1.2A charger
S4 - 2,600mah battery, 5.0V / 2.0A charger
G2 - 3,000mah battery, 5.0V / 1.8A charger

Hi
Looking at the service manual the charging is handled by a Texas Instruments chip http://www.ti.com/product/bq24192. QuickCharge is a function of the Qualcom PM8941 power management chip, however as the Qualcom chip isn't charging the battery (the BQ24192 is doing this) then QuickCharge can't be implemented by a firmware update.
Regards
Phil

only thing speaking for a stronger charger would be the parallel usage of the device while charging it.
at least in my Imagination. dont Know if its technically possible if that could make a difference, but i think so.
charging my Xperia z is much quicker if i dont Touch it while its charging.

But how come the LG G2 have Quick Charge then?

My N5 charges pretty quickly compared to any of the phones I've had in the past.

per specs, Nexus 5 is Quickcharge 1.0 only. No 2.0 support.

Thanks for sacrificing your batteries in the name of science. Apparently, running a lithium battery down to 0% is a no-no and will decrease the lifespan and capacity so should be limited...
http://forum.xda-developers.com/showthread.php?t=1169979
But then, I'd hope that they built in a 0% that is above that threshold. So maybe it's NOT a concern. Perhaps leaving the battery discharged for a month might drop it down that low, but that would mean you're on to your next device and battery.
Cheers, maybe I should just delete this post and not even send it. Nah...

where is quick charge in the menu? I can't find it o_o

The NX5 will NEVER have quick charge. It charges using TI's charging stuff. Therefore it will never work. Look it up. I'm not gonna bother looking it up again. I was disappointed when I saw that when it was first released.

Thanks. I thought it was an option somewhere I had to enable to make it charge faster. so it's just a passive hardware thing?

So you want to say that this is not fast charging? Barely used though, but powered on.

It's quicker than the Nexus 4 for example but is nowhere near the LG G2 which does have quick charge and it takes the phone 1:30 hours to charge a 3000 may battery...

Extremely slow charging?

The other night I put my note pro on the charger with around 28% battery. After 8+ hours charging it was only at like 90%. I have been noticing pretty much every time it charges. Is there something that I am missing? I am rooted, but don't mess around with much on this tablet simply because it doesn't need much tweaking. I am using an official Samsung USB 3.0 charger with a 3ft cable. So no non-standard overly long aftermarket cable or anything either.
I am thinking of doing a factory wipe on it, maybe that could help. Hope there isn't a physical issue with it because I could see Samsung denying me because of tripped Knox...
Thanks.

Whats your standby battery drain like? If you're seeing significant drain while not charging this might be an indication of something running in the background that's reducing your charge rate too. Is charging speed improved if the tablet is powered down?
As a point of reference using GSAM Battery Monitor I see a charge rate of about 1200ma at idle with screen brightness low. You may want to try a battery monitor app such as this, perhaps it will help pinpoint the issue.
Could be the charger itself . . .

You can also go Settings - General - Bttery and tap that grey bar (where reads how long you have been running since last charge)
Then check Awake.. If there is blue bar even when your device has been longer time without any using, it tells that some app or something is not letting the device go to sleep --> which drains battery.

Have you tried your original USB cable? The stock cable is longer than 3ft

Did you charge on Power Saving mode? I think, that option slow down charging

Did you turn off all running settings? (WiFi, GPS, Sync). Did you Greenify all Apps?

Thanks for pointing me to this app. I installed and will take a look at what my tablet is doing. Seems like I have been getting much lower "Screen on" times lately too. I don't recall installing anything that would do something to drain.
As for the charger, I bought the tablet from Amazon as open box. It was supposed to come with a charger but didn't. They gave me a partial refund and I bought a charger on ebay with the same model number as the stock one but it only came with a 3ft cable. I wouldn't think having a shorter cable would make a difference...

I never turn off settings while charging. I don't feel that you should need to. I generally keep GPS off all the time anyway, I have a phone for Maps!
Thanks for the replies all! I will report back on what I find.

You likely have an application causing drain and GSAM should help you figure that out.
In addition I would suspect the charger; check the voltage and see if it's rated for 5.3V at 2.0 amps.

Keep in mind that turning off WiFi speeds up the charging by about 70%. And since we're talking about a device with 9500mAh...
It's fine that you feel one should not be required to do so. To each their own. Physics, however, has no interest in 'feelings' and what people think should happen. Turning off a service that uses a lot of power means it'll stop draining a large percentage of the feeded charge. Elementary physics. (Just like how a cup is filled faster if you stop drinking from it whilst filling it.)

The charger that I have is model number: EP-TA10JWS
The output is rated for 5.3V and 2.0A.
I suppose there is a potential that I got a bum charger, or its a very sophisticated knock off. But the labeling all looks very legit and identical to my wifes Note 10.1 2014 charger.

So last night I tested and I TURNED OFF my tablet completely to charge. I think I had about 18% left when I put it on the charger and when I woke up about 7 hours later and turned it back on, it was at 91%. Does this sound even remotely close?
I also tested last night plugging in my charger and turning everything on the tablet off, WiFi, screen brightness all the way down, closed all open apps etc... In GSAM Battery Monitor my input was only like +800 mA. @muzzy996 you have 1200mA??? Seems like the issue must be the charger in light of my testing...
Another thing I tested though was using my wife's Note 10.1 2014 charger this morning. I believe it has the same output (5.3V / 2.0A) but I used the USB 2.0 cable that is included with it. I was only at like 650mA when charging. I think I will have to track down another charger and see if it makes a difference...
Thanks again for all the replies.

I believe there is a defect in the charging software or hardware. I used several iPad 2 car chargers rated for at least 10 watts. (5.2Volts x 2Amps) They take 5x longer to charge than the iPad. Talk about proprietary hardware/software.
The OEM charger EP-TA10JBE is rated at 5.3Volts x 2Amps. The voltage loss in the 4Ft cable supplied must be at least .1 volts, so I do not understand that the voltage difference should cause the charging rate to slow to a trickle.

I'm going to try this.
I'm having the same problem and I read the following in another thread. I'll let you know if it works for me. My charging time is not quite as slow as yours, but it's still slower than it was when I first opened the box and I've only had it less than 2 weeks.
"had the same problem after updating to 4.4.2. It only charged when off. When the device was on, it mentioned 'not charging' in the battery status, but in fact it did charge very slowly when the device was not in use, about 5% per hour.
Also when used, the battery was draining more quickly than before the upgrade.
This solved it for me:
- reboot in recovery mode (hold volume up, button and power while booting)
- clear cache partition
- reboot.
Looks like something in the cache is causing the system to consume (almost) more power than is supplied by the adapter..."

Working better
After clearing the system cache, the charge speed went up to about 22% per hour with the tablet shut off. Seems to be huge improvement in my case. I used the cable that came in the box with tablet.

The standard note 12.2 charger: EP-TA10JWS, The output is rated for 5.3V and 2.0A.
My Galaxy Note Edge has fast charging and regular charging capability. 2 outputs; 9.0V - 1.67A or 5.0V - 2.0A
Has anyone tried this/a fast charger with the note 12.2 ? Will it work ?
Probably not as it doesn't have the fast charging capability, but worth asking the tech savvy people out there.
Besides for travelling purposes it would be great just to carry one charger instead of 2.

Sorry yes, corrected.

Dont forget it has a 9500mAh battery. The Note 3 has 3200mAh and charges from 0 to 100 in 90 minutes. So you'll always be looking at at least 4-5 hours.
If you leave your connections(Wifi, gps, mobile data, etx), sync and apps running, don't complain that it takes ages to charge.
Fast Charge pre-S6 is Qualcomm tech. The new Exynos chips support their own Fast Charge, but that doesn't apply to the old Exynos devices.
The Snapdragon NotePro's have Qualcomm Fast charge. (Which is not the same as the one in the S6)
The Exynos devices do not. So the P900 will always be slower in charging than the P905.
If you have a p900 and it's slow to charge, that's why.

You can use the Note Edge charger, it also supplies normal levels for ordinary charging. I often use my Note 3 charger.

I don't know the output of your charger but the correct one should have 5.3 Volts, 2 Amps output. Using other chargers which has lower output such as 1 Amp will cause a longer time to charge.
In order to verify which one is at fault, everyone should have this tool, no more guessing when you can see the voltage and charging current .

You should swap one by one, using a known working charger and cable to verify which one is the source of problem. Start in order: charger, USB cable, USB port until problem solved.
If the reading is not 5.3 V, 1.7A, something is wrong with your charger, USB cable. or USB charging port ( new one is only around $12 ). When near full charged, current should be under 1 Amp.

The Note 3, TabPro and NotePro chargers are identical. They have literally the same EAN and product code. The only thing that varies is the cable.
I don't have any 1A chargers anymore, they're useless to me these days. Even all my car chargers are 2.1A.

Wired if you need a super quick charge to get max battery life as possible.
Wireless for convenience if you won't be needing the juice for a bit.

I use wireless wherever I don't need immediate charging.
Using the Samsung S Charger pad - Wide (here)
It's amazingly fast given that it's only got an output of 900mAh (or so it says)
The whole idea of fast charging sounds unsafe to me (probably isn't) but I have doubts of the life span of a battery that gets constantly charged that fast

One problem from wireless one, is that you can't use phone, because you're broking charging cycle (it will affects battery life). For example, a call.
So, wire even if at day I have time. And wireless at night when I'm sleeping.
For me is the best option. Is it?

Yeah fair point

I use wireless everywhere but the car. I have wireless bedside, and on my desk at work. It's super convenient and even though it won't charge during phone calls, keeping it out he dock keeps it charged up. If I am heavy on it, I just unplug the dock and plug in directly. In the car is a different ballgame. In Texas, the summers are hot, and I've seen phones shut off because of overheating. I don't want to add the heat from a wireless charger to that. Instead, I have a quick charge 2.0 charger to top off my phone quickly during trips.

Here are some charging numbers I took for just 10 minutes. The percentage shown is the amount gained in the 10 minute window. I made sure the phone just changed to the certain percentage before testing to make sure they were all the same. Meaning If the phone was at 34% when I plugged it in or ont he wireless charger, I waited until it changed to 35% and then did my 10 minute window.
Fast charge Charger
10 minutes 17%
Wireless charger (Duracell Powermat)
10 minutes 6%
Normal Samsung 1amp Charger
10 minutes 8%
So the wireless wasn't much slower than a normal charger

Could someone please recommend a Good fast charging wireless charger for the tmobile Gs6. Thanks In advance!!!

I just did a test of the Samsung Wireless base.
It charged from 55% to 100% in about 1:23:30. Not as fast as 2A wired, but still a decent rate.
{UPDATE}
S6 Adaptive Fast Charger: 55%-100% in 00:50:00. I expect the S4 2A charger to be faster, which will be my next test. And if so, "Adaptive Fast Charging" is very misleading as the emphasis seems to be on "fast" as opposed to adaptive", as most people care about speed and not Amp switching.
{UPDATE 2}
I have no screenshot for this because my phone reset the stopwatch when I tried to tale a screenshot. (It takes me about 6-7 tries to take a screenshot - it usually just goes to Google app when I try to screenshot. Very annoying.)
The constant 2A Samsung charger went from 55% to 100% in 00:53:00, so it seems the "Adaptive Fast Charger" was 3min faster. I'm very surprised, but the 3min doesn't make any difference in my life.

Cheap, and works with Otterbox Defender case on my S6.
Fast? I guess that depends on how you define it.

I´m wondering whether all wireless chargers works the same? I mean if they charge evenly fast and with same efficiency, as they all are the same Qi standard?

I'm guessing no. In almost everything made, there is a "standard" that the item is made to, but varying qualities of build and performance. Take Bluetooth, for example. All items are made to a specific Bluetooth spec and standard, but not all accessories, transmitters, and receivers work to equal quality. I think it's a matter of the lesser accessories being good enough for you.
And keep in mind that I'm not saying that the expensive ones will always work better and the cheaper worse - just that you can't expect them to all work the same. But one thing that is true the majority the time - "you get what you pay for". And sometimes you don't.

I think that wireless charging can be handy. For instance, at work, I sit at a desk in front of a computer all day. I'll make calls a few times throughout the day to clients, and whenever I'm not on the phone, I plop the phone onto the wireless charger, and let it charge up a little. Usually, when I go home at 4:30, i'll still have a full charge. I'll drain the full charge with games or whatever while I'm at home, and I always plug it in before I go to bed. I've never found myself with a dead phone, but If you were the kind of person who was on the move all day talking to people, having a wireless charger might not be very beneficial.
Here's the wired charger I use
And the Wireless.

The adaptive fast charging speeds up charging when the battery is low. As the battery get closer to full the fast charging slows down to prevent damage to the battery. If you redid your comparison from 5% charge to 50% charge you'd see a much larger difference between the normal and fast charger.

I have 3 off these around the house, no issues at all.
And they come in all kinds of colors/styles.

Ah. I'll never let my battery get that low, though, so I guess it's not of much benefit to me.

Quick charge or not?

Does this phone support quick charge? I ask because 2 coworkers got the Blu and let me play with it. Might be returning my Nexus 6 and grabbing one. Issue is I have the Anker 18W quick charger w/led. The led turns green whenever a phone that is quick charge compatible is plugged into it, and stays blue when a phone is charging at normal voltage. When I plug in my Nexus 6 or my Zenfone 2, or my wife's S6 the light turns green immediately, yet when I plug in the Pure XL it stays blue just like my older phones. So does this phone support quick charge really? I see in the specs it states it does.

The phone claims to have quick charge. I've been using it since last night and if it had quick charge it's a slow quick charge. Coming from the note 4 it's SIGNIFICANTLY slower for sure. It's border line a deal breaker for me. The battery life isn't as good so far and the quick charge is slower.

Im with you on the quick charge being slower. Coming from using the Nexus 6 for the past few weeks, I can argue that the battery life is slightly better than the Nexus, but the Nexus would charge lightning fast, kinda made the battery a non issue. Im gonna wait until the battery on my Nexus and the Blu are both at around 50%, then Ill plug the Nexus into a standard charger and the Blu into a quick charger and see if there is a difference.

But does blu support the quick charger of nexus 6 ? I think it is silly that now all the phones use same charging port but manufacturers make different quick charge protocols.
You can install a charge monitor app, for example "ampere" from market to see the charging speed. All that matters is the mA charge speed. Quick chargers will charge faster from 0% to 50%-85% because they can pump in power faster into the empty battery, but they have to slow down as the battery gets full or too warm.

I haven't gotten Ampere to show a normal drain value (0 mA is all it will display) and the charging values are all over the place (1.8A - 2.8A). I looked at various stories and MediaTek's specs on the MT6795 and there isn't anything about fast/quick charging. I think I charged about 40% (50% to 90%)in 20 minutes the second day I had it. It has a couple charge cycles on it now, though, so I will pay attention the next time the battery is low and see how fast it charges.

I will add that I have an Aukey QuickCharge 2.0 charger and it only shows a 1.4A charging rate but the Blu charger shows 2.8A so there is probably something MT specific going-on.

Quickcharge 2.0 charger is probably incompatible with MTK fast charge. 1.4A sounds like the normal charge current. But 2.0 - 2.8A sounds right for fast charging. Perhaps the values are correct, it may be fluctuating. If I remember correctly, I saw 2.2A in my nexus 6 when it was 75% charged. (I should also check it from empty but I usually just keep it in charge so charge never goes under 50%).

It does fast charge using the charger that came with the phone.... If you look at the charger specs it reads 5/9 volt 2.1 amps.... Probably has a small procceser in the charger the phone sends a signal to that switches it to 9 volt charge

My phone charges very fast with included charger. I also tried a no name Quick Charge adapter ... also charges fast, but first shows Over Voltage Warning

The rate of charge is much higher when the battery % is low.

My HTC One X9 chipset is Mediatek MT6795 Helio X10. At HTC India website, they say something like 'Fast charging (5V/1.5A)' which doesn't sound faster obviously and my phone takes 2 hours to charge. My Samsung Note 2 was still faster (5V/2A). Mediatek MT6795 supports Pump Express Plus charging. Do you think my HTC phone support faster charging (higher voltage charging)?

its been my expierence that using the included charger fast charges, but if i use a "quick charge" charger it slow charges... but if I use a generic 2.4A charger it charges fast... stock Samsung Note charger SUCKS on these phones

Golden Shovel for me, but I think there's no need to create another topic
I have the new Blu Vivo XI+, which came with a " fast charging 5v/2A charger", thing is my phone has the P60 processor, which supports Pump Express 4.0, thats 5v/5A, it's ridiculous that Blu is shipping a common charger with a processor capable of such fast charging, anyone knows if the technology must be enabled on the phone itself, or if I just buy a 5v/5a charger it will work?

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the OnePlus 5 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

It's about not only charging speeds... But also the heat while charging
And in both situations, dash charge is superior to any quickcharge solution i've tested.

I can confirm. Alot faster and still cool battery. It charges with 3 amperes through than with an anker charger that fills your battery with 1.2 amperes through.

Dash charging is the bomb. Even without the Dash charger, the phone charges awfully fast.

lighting fast

Easily gets through a day with heavy usage with plenty of power left in the battery.

Super fast charging speed.

from 5% to 100% at 68 minutes. No limits ROM, bluspark kernel

I don't think my phones ever overheated.
Dash charge works phenomenally well, I've never known a charger this fast.
Problem for me is I have a tonne of other USB-C chargers which even though they have similar voltage and amp output they sometimes charge slowly or normally, so you would need to buy another dash charge to get the same speeds.
I have another charger (Dash) but no second cable, lost it. Using another USB-C cable doesn't allow Dash, so the cable matters too.

I saw a video on youtube with charge speed comparison between flagship phones, one+5 was fastest there (1 hour 13 mins). pixel 2xl there was around 2 hours 40 mins)

啥？

wow, that's fast. what about battery health? I heard that quick charge can hurt the battery in few month

Fast charging only hurts the battery health if it overheats.

so this device can't be connected to wall charger more then 2 hours, right ?

The time connected to the charger isn't exactly a factor here. You could leave it on the charger for days and it likely won't get very hot, because it will only be trickle charging it to keep it at 100%.
Now, there are other things that cause battery life issues, but I was specifically referencing excessive heat, which is the number 1 battery killer.

My girlfriend oneplus 3 after 1.5 year still got 6 h + sot, dash charge is great

If my phone is on, it usually takes an hour or less. Since the last update it has been faster.

DASH charging is super fast, while charging with QC 2.0/3.0 charger or any other charger its reaaaaally slow.

No heating on charging even if i use this beast.
Gets me full charge in around 100 minutes.
Sometimes it charges really quick around one hourin my office (i think power supply in my office is better than my home) but takes 100 minutes at home mostly.
