Alright, so I have the dx with the stock battery, stock wall charger, and my gf has a fascinate, stock battery and charger, and she swears my charger is worlds faster than hers even tried switching and mine seems considerably faster. Both plugged into the wall not usb. So far it seems it might be, could a few people post some average charge times for a full charge from near dead and indicate from what percentage battery was at. Just wondering cause she is contemplating buying an dx charger.

Higher the amperage of the charger = Faster charge. Just keep voltage the same.
My charger charges my friends evolution much quicker for this reason
yes, that was what I was thinking as well, but tonight I ran into a buddy in school for some sort of electronics degree (I forget exactly what) who said the different duty cycles may be the culprit.
How long the charger must rest after doing work, ie, if you have your charger plugged in, it may only be charging half the time if its duty cycle is 50% just used for an example). So even if the numbers match 5 volts and 850 mA, the charge times can radically differ if the duty cycle were to be 30%. Although he could be completely wrong.... as I said hes still in school...
While I feel that increasing amperage by switching chargers could be partially dangerous to the device, if the difference is Duty Cycle, thats kinda a different story. Perhaps it would indicate the high temperature while charging as it does not allow the phone to cool between cycles? just a guess.... any input? still would like to see some numbers on charge time. maybe some numbers on non oem chargers too?
Hello friends,
So I just got my Note 4 and i'm wondering how long should I keep it in charge for the first time? And should I drain it on first use or charge it when it's at let's say 20%??
Thanks in advance.
14 hrs, dont drain, battery should be between 20-80% before charging in normal use, fast charge off.
@zurkx
Thanks for the reply.
Are you sure about the 14 hours??? I thought Li-ion batteries don't need that long of a charging time !!!

Please happily ignore that "advices".
Use Fast charge, charging takes exactly till the battery is full, that's about 1,5 hours for a full charge.
I don't see ANY sense in charging a LiIo battery "fuller than full", just impossible nonsense.
LiIo batteries suffer of aging, slightly increased by the number of charges, highly (!) increased by overheating, not of any memory effects.
There is NO "breaking in" of the Note 4s battery, amperage of fast charge doesn't come even near the safety limits, won't cause quick degradation or overheating.
So just don't listen go the immortal myths and "ancient wisdom" propagated by people not aware of the fact that battery technology indeed changed over the decades.

Thanks Chefprol.I have done some research on charging the battery and have come to a conclusion that once it's charged I can use it straight away but and then drain it to 18 to 20% then charge it fully.

Thanks ! i tought it would be a old myth to first drain the batery and then fully load it but as far as i know its only with old phones and mp3 players and such.
hope i will get my note 4 today ! waiting for it since monday
Fast Charge is not really a useful feature for me, it just hurts the battery more in the long run
what about the thoughts on conditioning the battery?

There's no need to condition the battery, its a lithium battery.
If you're having battery drain issues I would suggest you clear your data cache.

this is the same guy making up stuff about the note 4 GPS being bad.
dont listen to fools.
First charge needs to be 14 hours to trickle charge the battery to full and make sure the meter is calibrated to a full battery.
fast charge does reduce battery life since it charges at higher voltage and amperage. any battery gets damaged a little by that. best is a slow charge (preferably Qi) at a normal charging voltage. Slower the better for longer battery life. if you want convenience over battery life then by all means fast charge and mess it up and replace after 2-3 years.

I already advised to realize this is 2014 battery technology, not the ancient batteries of the past.
Short: There is no "trickle charge" with Lithium-Ion-batteries.
See this: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries - quote: "The difference lies in a higher voltage per cell, tighter voltage tolerance and the absence of trickle or float charge at full charge."
fast charge does reduce battery life since it charges at higher voltage and amperage. any battery gets damaged a little by that.

Quote: "The charge rate of a typical consumer Li-ion battery is between 0.5 and 1C in Stage 1, and the charge time is about three hours. Manufacturers recommend charging the 18650 cell at 0.8C or less."
"C" is the capacity, 3220 mAh with our Note 4's battery. So we're save to charge with a current (milliamperes, "mA") of up to 3220 mA - if we follow the manufacturer's advice for the older type of batteries of that kind (18650 is an old warrior in the field), there's still 2576 A left.
So what does our fast charge supply deliver ? Look at it's ratings: 5 V, 2 A (2000 mA).
So even fast charge is far below the limits - our real limit is 3220 mA, but fast charging just uses 2000 mA.
Sound and safe.
Wonder about me highlighting "higher voltage" in zurkx's highly elaborate statement in red ? - Answer is above: The voltage does NOT change, it is NOT higher. Of course not !
The worst enemies of LiIon batteries are heat and age.
Heat is generated by a) placing the device at a hot spot (like behind the car's windscreen or in bright sunlight), b) by using demanding features like 4K video recording or highend games, c) by charging .
a) Your call. Just don't let your Note get hot. Overheating destroys your battery in no time. We're lucky we've got an exchangeable battery - so nothing to really worry about.
b) Your call. See a).
c) Charging produces some heat, especially on the "last mile", when the battery is "almost full", because the battery is a bit reluctant of getting charged up to the brim. So more heat is generated in that last phase. It's not much, won't reach the safety limits. It just can't, because the build-in charging circuits limits the current if heat gets up.
By the way: That integrated charging circuits are propped with safety measures, checking charge, condition, temperature and the like.
So even if you hook up a charger capable of providing 20 whopping amperes, the circuits just won't let that happen.
There is no way of providing the battery too much current; it's automatically limited.
best is a slow charge (preferably Qi) at a normal charging voltage. Slower the better for longer battery life.

Again; welcome to the 21st century. We don't need any slow charge. It's the opposite.
Charging right slow has the danger that apps on the phone draw more power than the charge provides. That may drain your battery instead of filling it.
Plus: If you hook up the charger for long, it will be recharged (charge gets "topped off") frequenly. And every new charging attempt has a slightly negative impact on the battery's life; it's like wearing it a bit down. - Charge often, reduce your battery's life. That damage is tiny, by the way. But it is there, so hooking up your charger for many hours slowly kills your battery.
Now for the aging:
if you want convenience over battery life then by all means fast charge and mess it up and replace after 2-3 years.

Click to collapse
LiIon battery ARE AGING, up from the time of manufacture.
You all know that: You charge a device like you're told by the instructions - but after 1 to 3 years you notice a severe drop of usage time, a drop of capacity.
That's aging.
NOTHING you can do against that but buying a new battery.
So your battery will lose it's capacity over time; if you use it or not. You all know that, you all experienced that.
With the Note 4, we can happily buy a new battery if the old one runs out; it's that simple. But as a normal Li Ion battery reaches it's shelf live after 2 or 3 years anyway, there's NO (!) need of burdening it and you with slow charge. The results are exactly the same, with the difference that you save precious time with fast charging.
And now allow me quoting again:

The QuickCharge tech charges at higher VOLTAGE and AMPERAGE.

Max Current 2A 3A
Snapdragon 200, 400, 410, 615, 800, 801, 805
The rest is just BS as usual. You have no idea what youre talking about. Dumping 9V (Samsung Note 4 AFC) into a 5V battery makes it charge hotter and faster and degrades it significantly. After two weeks of fast charge i lost a small chunk off the top of my brand new battery.
just bad advice as usual.

Yes, indeed. I was completely wrong by believing you'd understand some simple things.
In fact, I am not sure if I should take your statements for serious or just for a joke.

Click to expand...

So you REALLY believe that changes of the output voltage of the POWER SUPPLY lead to the BATTERY charged with more volts ?
You can't be serious. That's technically impossible.
Let's put it easy:
If you insert your power supply into a 110 V receptacle in the USA, you get 5 V output.
So according to your "logic", using the same power supply in Europe (230 V) increases the voltage to 10 V ?
No. Just NO.
That higher POWER SUPPLY voltage is used for fulfilling the rule W = V * A (Watt = Volt * Ampere); just to be able to squeeze more power through the power supply's cable.
In the Note 4 and in the charging circuit, that voltage OF COURSE will be regulated down to the regular charging voltage - just with the benefit to carry more amperes.
So the CHARGING VOLTAGE stays the same; it does NOT follow the voltage supplied by the POWER SUPPLY. It never does.
So fast charging does NOT (read that: NOT !) increase the charging voltage. It cannot.
Got that now ? - Or do I need to put it ever more simple ?
It does not help using swearing words like "fool" or "bull****".
But it could help just saying: "Oh, sorry, I was wrong. - My apologies."
Make yourself at home with the basics of lithium ion and charging technology. THEN speak up.
Ah, overlooked something:
After two weeks of fast charge i lost a small chunk off the top of my brand new battery.

1) Hope that chunk fell somewhere you were able to pick it up again.
2) How to you KNOW that ? I expect a detailled description about how you did the magic of finding out that your battery doesn't charge to 100 %.
3) If you KNEW that fast charging would kill your battery, wise man - why did you allegedly use the feature ? - Sorry, man... Your statements are not very trustworthy. I guess you never used that feature, just say so to strengthen your shaky point of view. Please don't mess with a perception psychologist.
4) If your battery really suffered, that might be due to your highly acclaimed and absolutely pointless 14-hours-charging-marathons, causing a permanent charge on/charge off cycle, weakening your battery.
So please just stop bashing a real useful feature of the Note 4. If you just love waiting ages for batteries to charge - your preference. But please stop spreading false facts about things you very obviously are not at home with.
And a last thing which might stop that aimless harassing fire of yours: I am HAM, a licenced amateur radio operator, holding the highest German licence class. These are the people who know a bit about volts and amperes.
how hard is it for you to understand that quickcharge 2.0 outputs higher VOLTAGE and AMPERAGE to charge the battery ? The charger charges the BATTERY AT 9V 1.67A up to 50% and then switches over to the regular 5V 2A charge rate. INPUT VOLTAGE (110V or 230V) has nothing to do with OUTPUT VOLTAGE. It charges the battery at 9V REGARDLESS of INPUT VOLTAGE.
edit:
also it has nothing to do with the cable. you must be crazy if you think a cable issue exists whether you transfer 15W or 10W across it. the cable is rated for well beyond that. the reason for the higher voltage is that modern lithium ions can accept high voltage charge rates with limited damage at low amperage. the reason they cut it off at 50% is the battery would be severely damaged if you tried to charge it to 100% and overshot. so yes quickcharge 2.0 really does charge your battery at a higher voltage than it was designed to be charged at. and no they dont have a magical transformer on your phone to go from 9V to 5V. otherwise they would be using it all the time and fast charge 9V to 100%. the wall plug is the only thing which has a transformer and the phone uses what it gets from there. they arent going to build half of another wall plug (9V DC-DC) and stuff it into the phone. it would generate heat and add bulk. Instead the PMIC "spikes" the battery with higher voltage and keeps it roughly constant (load modulation) by communicating with the quickcharge 2.0 AFC on the other end.
Hopeless.
I just love these battery threads, there's always some muppet who says the battery needs conditioning and must first be charged for a suitably ridiculous length of time. When it's charged it's charged, lithium batteries have no memory effect so the idea of conditioning them is moronic

no need to keep it for 14 hours, as they said in the catalog you only need to charge it till it's full, then unplug the charger.
Hello again !
After all cooled down a bit, here's some more information about that dreaded HIGH VOLTAGE fast charging uses which seemingly makes some of you wet your pants.
First, there's an experiment you can do yourself. You don't need to do - but it's quite impressive and gives you some proof of the things I say.
Get two 9 V batteries; the small rectangle ones we all know. Connect the positive contact of the first battery with the negative contact of the second. Thus you get an 18 volts DC power source.
Get a thin, isolated wire, short-circuit the open contacts with the wire. Wait.
Nothing special will happen, maybe the wire will get a little warm - and your batteries will eventually die.
(If you use a VERY thing wires, it might heat up.)
Now take a length of the same wire, do the same using your car's battery (12 – 13.8 V DC).
WARNING !
1) Take the battery out of the car, set it on solid ground with nothing combustible near !!! Do NOT try this with the battery still in the car !!!
2) Use pliers to connect the wire with the battery contacts !!!
3) Do that OUTDOORS !!!
Short-circuit the battery contacts using the pliers with the wire.
You don't need to wait. The cable will turn into a smoking, burning, white-hot thing in an instant.
Huh ? - We've got 18 V with just nothing happening, we've got just 12 V wreaking instant havoc and destruction !?
Amperage is the key !
Voltage alone does not cause the destruction, it's the amperage.
9 V batteries cannot provide sufficient amperes for killing the wire; 12 V car batteries do.
Short: High amperage kills wires, high voltage doesn't.
So back to our topic...
To fast charge our Note 4's battery, we need power, watts. But the tiny wires in the Note 4 can't withstand a high wattage; they would heat up like the wire connected to the 12 V car battery.
So Samsung uses a little trick, according to Ohm's law: W = V * A, W is watts, V is volts, A is amperes.
So we can achieve a high wattage by EITHER using a higher voltage OR a higher amperage.
Higher amperage does not work because it will kill the tiny wires in the Note.
So Samsung raised the voltage for carrying more watts from the power supply via the internal Note 4's cabling to the charging circuit.
That higher voltage gets transformed down to the normal charging voltage at the charging circuit.
Your battery is charged with the usual voltage, but with the benefits of a higher amperage.
That's all the magic: That higher voltage is used to carry more wattage to the charging circuit, but not beyond. Nothing else.
And that's why it does not harm your battery; charging voltage will not change - your battery just gets charged faster, always monitored by the charging circuit which will lower the charge accordingly if needed, so your battery will always be safe. That's why the "last mile" (charge from about 92 % to 100 %) takes more time to charge - because the charging circuit automatically lowers the charge to protect your battery.
So don't be afraid of that higher voltage; it never reaches your battery, it is just a means for transferring higher wattage via tiny wires.
Note: You ever wondered why Europeans use 230 V instead of 110 V ? - That's the reason. Being able to carry more watts over regular power lines without risking the wires heating up too much. It's not a means of destruction, it's the opposite.
I'm wondering if the heat I hear about being generated before the charging rate slows down after 50% would have any negative impact on battery life. Would there be any benefit in using my multi-port charger for overnight charges when I am not in a hurry to charge the battery?
Also, I assume that the battery doesn't have any memory, and that there's no reason to break it in, fully discharge periodically, etc. and that it's okay to charge a little or a lot regardless of the current charge state. Is that correct?
This is a question i would like to know the answer to as well
I did a slow charge last night and the battery seemed to discharge s little slower this morning fwiw, but that's not terribly scientific.

Fast Charging Lithium = Battery damage. It's basic chemistry. The cells take mechanical damage from expanding too quickly. So, for best longevity, charge her with like a .7 to 1 amp charger.

Thank you. I had thought the same thing. No one had the time to give me any detailed information, so I researched. I can't post links, but the following articles are helpful and will show up first in a search for the title
'Will speed chargers kill your battery?'
'BU-401a: Fast and Ultra-fast Chargers'
A conventional phone charger can only supply the current and voltage that is safe for a battery at all charge levels. In other words, it is must use the least common denominator. Quick Charge makes this process much more active by monitoring max current, max voltage, and temperature so that it can supply more power when it is safe and less power when it is not. Quick Charge will always keep the current, voltage, and temperature within the battery's designed specifications.
In terms of battery memory effect, no, modern lithium based batteries do not have any sort of memory-like effect. This is mostly associated with older and cheaper NiCad type batteries. This is one of those things that people seem to have a really hard time moving past.
People worry far too much about babying their battery.
Assuming you are going to use the phone for ~2 years then a properly designed fast charger should have a negligible effect on battery life. After 2 years of continuous usage all bets are off whether you used a fast charger or not.
If you really want to worry about how to treat your battery then there are two things you should try not to do. Don't let the battery go all the way to 0% and let it sit like that for a year. Don't leave your phone on your dash in direct sunlight everyday. Outside of those two things there's not much you can do to change the lifetime of your battery so just use the damn thing. =P

I had researched the topic and learned what you have stated, but I really appreciate you taking the time to write this fuller explanation. I wished to take every reasonable precaution to maximize battery life, given the battery is not easily replaced.
There have been references published claiming that charging faster (higher current) shortens overall Li-Ion battery life.
Mechanism may be related to heat.
One thing the Qualcomm Quick Charge 2.0 (used in the Snapdragon 808) does is increase voltage at the charger from standard USB 5V, to 9V and 12V, for higher charge rates (power) at still-moderate current (to keep heat dissipation down).
I measured 1.1 to 2.3 amps at ~9V with QC 2.0 charger on the MXPE, with the higher current measurements at lower State of Charge (SoC). Have not seen 12V yet, but I only tried it down to 45% SoC (2.3 amps at 9V), I imagine it bumps up to 12V when the battery is discharged further, nearer to complete discharge.
This charger is rated for
5V, 4A
9V, 2.22A
12V, 2.5A
20V, 1.0A
So the max power fed to the battery would be 28W (12V*2.5A).
(This is the Power Partners PEAW30-12-USB, supposedly a 30W charger. So much for integrity in advertising.)
So the current is kept to a manageable level to control heat dissipation (therefore max temperatures), from the charger to (somewhere in the phone). But I believe that at the battery itself, more rapid charging (higher power) would still require higher current, because voltages have to be limited in the battery itself, so one would think heat dissipation (> max temperatures) would still be a problem in the battery itself. Does that shorten battery life?
The answer is probably: Who cares. Because: Li-Ion batteries have a 2-3 year life in any case, regardless of their service life or even if they are not used at all. They age and exhibit substantial capacity decline over time. Discharge/charge cycles hasten the capacity decline, but the battery is only good for 2-3 years, give or take, no matter what. And since aftermarket replacement batteries are inferior, unsafe, and stale, there is no reason to try to hang on to your phone for more than 2-3 years in any case. (Especially since the "non-user-replaceable" batteries can be a pain in the a** to R&R. The Moto X Pure 2015 battery is one of those. Some phones actually incur permanent damage to seals if the battery is removed/replaced - the Kyocera Hydro Wave is this way.)
You say "but you could replace the battery with an OEM battery". There are two types of OEM Li-Ion phone batteries on the market that an individual consumer can buy retail, when their phone is 2 years old or more: Used stale batteries (look up "reverse logistics"), and "new" (i.e. not put into service yet) stale batteries. Good luck finding a fresh, new OEM Li-Ion battery for your 2 year old or older phone (out of production for at least a year).
Been down this road before. Wasted lots of time and money replacing phone batteries after 2-3 years. From now on I'm going to stop coddling phone batteries, stop replacing them after 2-3 years, and just figure on a new phone every 2-3 years. It's the only way to get a fresh, new Li-Ion phone battery. (And get the phone right when it is released, like the MXPE this month. That way you are more sure the battery is fresh.)
I think everything in the wireless phone paradigm is increasingly heading that way anyway. Everything, and I mean everything, pushes the market to a 2 year product life cycle. Batteries last 2 years. Increasingly, batteries are not made to be replaceable. Carriers are changing networks so fast you need a new phone every 2 for that alone. New OS/SW overloads hardware older than 2 years. Displays may fade over a couple years. USB connectors wear out. Just relax and go with it. Marvel at the Qualcomm Quick Charge 2.0 (I am). You'll be happier with a new phone every 2 years.
Sorry for the long rant.
Sorry for the kind of off topic, but it's kind of related... is it okay to use other devices with the included fast charger? I just hate having 2 micro usb chargers plugged in, when I could use just one

Yes, the Moto Turbo Charger can be used with any MicroUSB charging device. It will adjust charging as needed for the individual device. Moto made the Turbo Charger, to be a single charger for all MicroUSB devices.
If the battery is kept well charged, which Turbo Charging helps to accomplish. That's better to me, than more drain and slower chargers that leave the battery more drained overall. The batteries are supposed to last longer when kept fully charged more often.

"...since Quick Charge 2.0 is compatible and interoperable, a certified adapter can be used with a non-Quick Charge 2.0 device, though the fast charging benefits of Quick Charge 2.0 will not be available. "

By all appearances, Motorola's "TurboPower™ Charging" is nothing more than Qualcomm Quick Charge 2.0. (That's what Snapdragon 808 in the XT1575 uses.)
The third-party Qualcomm Quick Charge 2.0 chargers I bought are recognized as "Turbo" and function with the XT1575, just like the Motorola charger that came with the XT1575.
(There are a LOT of Qualcomm-certified QC 2.0 chargers for sale by third-party names. Qualcomm has been BUSY. )
To slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?

Moto doesn't have the option in settings, it uses industry standard Qualcomm Quick Charge standard rather than a OS hack like Samsung (no offense)... If it is connected to a QC 2.0 charger, it will negotiate the appropriate charge rate, if it is connected to a "standard" charger it will charge normally.
I don't think you can accurately measure battery/charge cycles... even if you could it would be extremely deceiving, what would be considered a cycle? Charging at 50%, 30%, 10%, and to what point 75%, 80%, 100%? Too much room for interpretation here that could be swayed either way depending on the person/app counting it's point of view.

Thanks for replying dear. So, for S7 I have turned off fast charge, should I now charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
For Moto G, the question is the same as above.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?
And I have signed your petition Brother. I hope they listen to the users.

Does Fast Charge hurt the battery life, no, at least not directly... heat does. Using an older style charger will avoid Quick Charging but I think that foregoing that benefit for a few more days of battery life is hardly worth it. I frequently have 30-60 minutes to charge, not 3-5 hours, so quick charge is nice, if it takes few days off the longevity of the battery so be it. Those who think it cuts the battery life by 20, 30, even 50% are wrong, that simply isn't the case because of Fast Charge itself.
The Moto G isn't an issue here, it doesn't support Quick Charge until the 4th generation, but why give up the feature?
I don't think the "rules" of charging apply as much as people think they do... I charge mine overnight and whenever it needs it during the day, if it does. There is no need to do anything special.

Thanks for the wonderful and detailed reply. I am going to try, not stick, to slow charging to see the difference in heating of the battery. My SIII's charger 's input is 150-300VAC, 50-60 hz 0.15AA, output- 5.0V-1.0A and S7's details are input 100-240V 50-60hz 0.5A, output- 9.0V= 1.67 A or 5.0V=2.0A. Can I use the S3's charger to charge S7 after turning of fast charge or is there a voltage difference or something? G4 is at home, don't know about its details. Also in my country the battery or the replacement parts are way too expensive.
i have had the V20 for about 12 hours in which time it charged from about 50% to about 75% ... my Note would accomplish the same in about 15 minutes ... and yet the V20 is supposed to run the same type of quick charger on the same size battery ... something about this doesn't rub me the right way
yes i did use the phone and unplug it a few times etc but it still should have been much faster ...
it was connected using its own cable and charger BUT through a USB extension cord ... so then i thought maybe that's the problem - maybe i need a longer type C cable and to get rid of extension cord ... but i need to have an answer to that BEFORE buying new cables ...
so i plugged it in directly ( no extension ) and tried to see if it charges in correct mode ...
and here is where i face plant into a wall of excruciating stupidity ... every single app out there measures charging current, whereas what i really want to know is whether the charger is running at 5V standard voltage or using the quick charge 9V voltage ... amazingly there doesn't seem to be an app to show this - or is there ?
my galaxy note would simply say " adaptive quick charger connected " when plugged into quick charger but the V20 doesn't say anything like that.
accubattery app says my screen on charging rate is 760 ma and screen off is 1760 ma ... and the charger of course states 1.8 A so that's consistent ... but is that at 5V or at 9V ? the charger supports both - which one is it ?
this is killing me - so much stupidity. it shouldn't be that hard to figure out whether the phone is charging correctly or not.
anybody have an idea how i could find out whether the charger is actually stepping up to 9V without physically cutting the USB cable and using my multimeter ?
EDIT: i realized i have a kill-a-watt ( actually two of them ) and i can measure power draw from 120V outlet ... so i did that. the draw fluctuated from about 6 to 13 watt. now if we assume 90% efficiency on the charger then full power would have to draw 18 watt from outlet - clearly it never got close. on the other hand at 5V it should have maxed out at around 10 watt power draw, and it went quite a bit over that so it would seem to be using the 9V mode ...
at this point however i'm up to 90% battery and can't expect it to charge at full rate any more as some battery charging algorithms taper off above 80% or so ...
i tried with and without extension cord and noticed no difference ... also if i remember correctly my Note also charged fine over this same extension cord ... but i'm not sure
EDIT: played with turning off 2nd screen as well as shutting down device completely - this phone is crazy. power draw is all the place - at one point it went to ZERO and stayed there until i unplugged it and plugged it back in, then it would fluctuate between zero and 14 watts ...
you know back in the day i had LG Nitro HD and it had worst battery performance of any phone ever ... and this V20 seems to be living up to that legacy. WTF.
anyway, it seems the charger and the cable and extension are not to blame - it seems there is some kind of software weirdness that is resulting in very sporadic power draw ...
slow charging is one of the reasons i switched from iPhone back to Android - i expected this V20 to perform similarly ( blazing fast charging ) to the Note 4 i had before the iPhone 6S Plus ... but it's charging performance so far is almost identical to the iPhone - slow as a snail.
i already spent $80 on case and screen protector and i'm supposed to spend a bunch more on extra cables and memory card as well as sell my iPhone and at the same time i'm thinking - maybe i should just return it ? going to have to observe it for a while longer before making any decisions either way ... terrible.
The V20 is QC 3.0
The Note 5 is QC 2.0
The V20 will negotiate with a 3.0 charger to tell the charger what power it requires at that moment so power will fluctuate during charging.
this will show you which devices are 3.0 and 2.0

yeah it fluctuates a lot. i gave up on apps and just using Kill-a-watt now which is a physical power meter you insert into 120V outlet. it shows power draw from charger, not output, but we can assume about 90% efficiency from input to output of charger.
i let the V20 drain to 40% overnight and restarted the test today. with the extension cord it went up to 16 watt draw from outlet and stayed there - charge quickly went up to 55% then i tried without the extension cord and now its only at 11 watts. this is with both screens off. so far my conclusion is that using an extension cord makes no difference but the level of charge on the phone does impact the charging speed. you need to drain the phone to measure full charging speed.
i will continue with my testing but i am somewhat relieved. 16 watts is close to spec, in fact the spec is 16 watt but on the OUTPUT side of charger, not input, so i'm withing about 10% of spec.
i'm also a lot less nervous buying charging cables now that i verified 16 watt charging over many years old USB 2.0 extension cord ...
EDIT: wow it went from 55% to 68% while i was typing this message ! this is very different from what i saw yesterday ... it was running at 11 watts while i was typing. looks like the phone charges fast as long as it is: 1) drained and 2) left alone. if the phone is almost full and you keep playing with it the level of charge barely changes.
EDIT: at 89% charge it's now down to just 4 watts power draw from outlet ... 25% of what it was pulling at 40% charge. so far it looks like it tapers charging speed off gradually with charge level - starts early and tapers it off to almost nothing as it nears full charge ... and all the while it fluctuates with processor and screen use and probably other factors such as temperature. maybe the reason it went to 16 watts when i plugged it in the morning is that the phone was cold from not being used all night and perhaps it now warmed up so the power got tapered.
maybe i'll stop testing it - it seems to be working correctly, just not the way i originally expected it to.
overall i'm disappointed with this phone but the only phone i would trade it for is Pixel XL 128 GB Very Black which is unavailable ... so i guess i will keep it.
the phone i'm most impressed with right now is ZTE Axon 7 i got for my mother - it is shockingly good - if it wasn't for FM radio, IR Blaster, Removable Battery, Laser Autofocus, Dual Camera, Dual Screen and Nougat i would even say the ZTE Axon 7 is BETTER than V20. the main problem with ZTE is it's just not expensive enough for my ego - otherwise it is great. the screen is is super sharp, vivid and punchy, the front facing speakers are loud and crisp and then there's the 2 year warranty. i'm jealous ...
but i will stick with V20 to protect my dignity. because let's face it - if i'm out on a date i want to have the latest, most technologically advanced and most expensive phone - not the cheapest phone, even if it is just as good or better. really happy with my decision to get Axon 7 for my mom though. she loves it as well.
The way QC works is that it will charge fastest from low power until around 70-80% and then slow down A LOT to help preserve the battery. That is why you saw a high wattage and then when you got into the 80's you saw a very low wattage.
QC is mainly for you to get 40-50% of battery power in a relative short amount of time when your battery is low.
I bought a little device that measures the voltage and current of the charge. And I'm using my own Quick Charge 3.0 wall charger.
When the screen is off or powered down, it charges at 9V/1.8A max. Resulting in about 16W of power. Which is pretty much what the supplied LG charger delivers.
When the screen is on, it charges at 5V/0.5A
My QC3.0 charger is capable of up to 9V/2A and 12V/1.5A, 18W of power. The V20 doesn't seem to draw that much power. And now I'm starting to doubt the V20 is truly a QC3.0 device.

I was getting 9.2v @ 1.67A = 15w of power. This is the max that my USB multimeter can do so it would seem that this charger is good for QC 3.0 as it did fluctuate voltage as needed.

That is still wasteful use on a battery and giving the next guy a raw deal. But to each his own. I try and make everything last and more efficient so the next person feels like they are truly getting an almost lightly used phone. If I sell my note4, they're going to get a lightly used battery on top of the 3 extras, with fixed GPS and better reception and cleaned out USB port with no oxidization. Same with my HTC m8 though that was only used as daily driver for two weeks and then a DAP for trips and occasional home use. Definitely selling the m8. They are basically getting a lightly used phone and the battery should still have some good life coming out of it. And personally I think jump is overpriced leasing but I guess you can drive it like you stole it. I prefer handing down the best experience I can to the next person.

Just tested this one at work. Phone was at 28% and I had been streaming Youtube for a good 2 hours before doing the test.
Ended up pulling 9.17v @ 1.68A = 15.40 watts (again maximum that my tester can do).
I'll be ordering a new tester that can handle up to 25A and testing again to see if I can pull the max 18watts of power that the QC 3.0 chargers says it can deliver

I see.
This looks like a good device.
There are time on my v10 where I'll plug it in and it will charge at a reduced rate so I have to unplug it and plug it back it and it changes to fast charge, that's just been my experience. This is using factory plug and adapter too.
So you might want to make sure the phone says "fast charging" and not "charging".

Hi,
I was video calling someone for a group project, and I was using a regular (not turbo) charger to charge my phone while i was at it. when I started, my phone was at 5%. Then it went to 0% and died, even though the charger was still plugged in. Is there any way to stop it from losing charge while its plugged in like this?
Use a faster charger. 5V 1A is fine to charge it when not in use but if you use it intensively like you did (screen on and high network usage) it is not enough. I would use at minimum a 5V 2A or the turbo charger.

You are mostly right, but the phone will not draw in excess of about 1200mA from any non-turbo charger, a larger charger is not important and will give no gain, but it doesn't hurt anything either.
The Moto X has a very large current draw off the battery when using the display actively, and at high brightness it gets almost ridiculously high, and add in intensive networking, high CPU usage (encode/decode video streams in real-time), and the power draw can easily exceed 1A or even more, so I am not surprised the battery drained while connected.
I am not an advocate of Turbo charging either, Qualcomm Quick Charge 2.0 can be hard on batteries, not in itself but the heat build up while using the device and turbo charging at the same time can easily exceed acceptable thresholds, but sometimes it is necessary with this device.

I remember reading that quick charge is deactivated when the screen is on (reverting back to 5V) to avoid overheating so I don't see using the turbocharger when using the phone as worst than any other charger or any better for that matter.
But yes, he shouldn't have started his chat with a MXPE at 5% battery left .

Hmm... I hadn't heard that but it makes perfect sense. Personally, I am usually looking for a charger if my phone falls under 40% unless it's within a few hours of bed time.
