Hey guys,
What’s the maximum possible ampere for the Nexus 4 without damaging it?
The standard charger has 1,2A, so I guess that’s a save value.
My new EasyAcc Power Bank supports up to 2,1A, which would be really fast loading I guess.
But I don't want to damage it so I use the 1,3A slot until I know better.
Greetings
The service manual says the charging current is limited to 900 mA. So a higher capacity charger will only allow faster charging while the phone is working. So no faster charge, just not 'losing charge' if connected and working.
The service manual also claims the PMIC protects up to 28 volt. So I suppose it will also not draw too much current if the voltage is right.

High amperage isn't something to worry about. Voltage is the important factor.

+1. i'm using a 2.5A portapow 5v charger with no ill effects.
Amps are not "pushed" to the device; rather it "pulls" what it needs.
I just noticed that Samsung is treating our batteries in a rude manner: they limit the charging voltage at 4.3v which drastically reduces battery life. I have searched all over the internet and I could not find a way to limit the maximum charging voltage. Is there any way to limit the charging voltage?
I measured the voltage with an intelligent charger, at first I got an overvoltage error as I tried to discharge the battery. I really don't feel comfortable driving around with a bomb in my car as Samsung did have issues with exploding batteries. The ideal voltage must be around 4.1v, maximum 4.2v
So you measured the voltage while it was charging in the phone? Not sure how you hooked up an intelligent charger to the battery while it's in the phone charging by the phone.
they limit the charging voltage at 4.3v which drastically reduces battery life.

How does it reduce it?
And as far as I know, the charging voltage is 5.3V for the standard charger.
I was measuring the battery outside the phone after 1 day when I got out the battery out of the phone, fully charged.
Someguyfromhell, the USB voltage does not play a role here, the charging electronics is in the phone matters, USB provides, as you say, a fixed voltage.
Inx64, is there perhaps an ingeneering menu concerning the charging process where you can modify charging parameters?
I think you can measure voltage with this code *#0228#
Knowing the voltage from the menu is easy, controlling the charging voltage aparently not so easy, though.
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.

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.

Click to collapse
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 expand...
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:

Have a nice day, all of you except one.
youre completely wrong.
The QuickCharge tech charges at higher VOLTAGE and AMPERAGE.
http://www.androidauthority.com/quick-charge-explained-563838/
Quick Charge 2.0
Voltages 5v 5v / 9v / 12v
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...
Click to collapse
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

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.
Hi guys,
N910C with Exynos here.
I have some questions for you guys.
1) Is it beneficial to use a generic (but good) 1/2 A (amp) 5 V (volts) charger over the Samsung charger?
2) What happens if I leave "fast charge" option on? Will it charge faster? Will it try to?
3) When using the provided Samsung charger, is it better for the battery to leave the "fast charge" option off?
4) Is the fast charge (or any fast charged charge) as good and efficient(?) as a 'slow' charge? Will they last the same?
5) What if I turn off the phone, is it going to "fast charge" by default when using the the provided charger?
Thanks in advance guys!

2) What happens if I leave "fast charge" option on? Will it charge faster? Will it try to?
Click to expand...
Click to collapse
It will charge slowly. Reason: Fast charging uses a slightly higher voltage for transferring the charge to the charging circuit. That's to keep the amperage low, so the tiny wires won't overheat. It's just according to the formula W = V x A: You can increase the wattage by increasing the amperage (heating up the wires) or by increasing the voltage (keeping the wires cool).
That's the reason why many countries don't use 110 V but 230 V - to decrease the burden on the electricity lines as you can then safely transfer more watts through the same lines. It's a kind of safety measure.
3) When using the provided Samsung charger, is it better for the battery to leave the "fast charge" option off?

If you enabled that in the settings, yes. Otherwise: No.
One question is missing: "Does Fast charge harm my battery if charging under hot climate conditions?"
Answer: No. There are temperature sensors in the battery, decreasing or even stopping the charge if the temperature gets too high.
Short: The difference between slow and fast charging is - slow charging charges slow. And that's it.

To be honest: You already answered your own question - by asking your questions.
If you have a look around XDA, you'll find countless threads discussing the "problem" - many users fear Fast charging may harm their battery.
Some users even believe the battery would be charged with an overvoltage (as that voltage is mentioned on the rating plate of the charger), thus causing damage.
No, not true. That higher voltage is just used for safely "transporting" the charge through the wires by keeping the amperage low. After that, the charging circuit will regulate voltage and amperage down to healthy levels prior to reaching the battery.
But people get misled by many self-proclaimed "experts" (which will surely show up here, too) praying that Fast charge is a work of evil; just wait.
That's why Samsung made that feature an option, not a rule. A courtesy for the overcautious.

I'd stick with the original Samsung batteries. They had problems in the past (deforming, bulging S4 batteries losing almost all of their capacity - I had one of those myself, got exchanged for free), but I guess they solved the problem.
Reason is: Li-Ion batteries may have different charging parameters; like maximum allowable current.
The Fast charger was made specifically for the Note 4s battery. If you buy a different type, the fast charging current may exceed the current rating of a third party battery, leading to highly unwanted effects including destruction of the battery.
This is not too likely because each battery has (or should have) a built-in charging circuit for limiting the current, which even switches off charging if the battery's temperature reaches unhealthy levels. But it's still possible, depending on the battery type and manufacturer. I wouldn't place any high bets on charging circuits of cheap batteries; everything's possible.
That's why it's best to stick with original batteries - at least in this case.

Yeah this is right but all elettronic components have a threshold. If you exceed the limit the components burn. So this is the question. What is this limit?

Yes, you can find both of the apps on Play store.

Yeah this is right but all elettronic components have a threshold. If you exceed the limit the components burn. So this is the question. What is this limit?
On the charger there is 1.8 mAh for current. But my powebank have 2.1 mAh for the output. So the LG G6 support this amperage?

Well, kind of. The phone will not draw more current than it is able to handle. Using a power source that's capable of 2.1A will not hurt a device that can only draw 1A. The rating of your powerbank is merely the maximum current it can supply while maintaining its rated voltage.
See this article that shows how the phone is smart and will vary the current (amps) that it pulls from the charger, and will be careful to protect the battery and not pull too much current as the battery reaches full charge:
https://gtrusted.com/the-lg-g6-charger-uses-qualcomm-quick-charge-3-0-instead-of-usb-power-delivery
Example snippet from the article: "while the current jumps around before settling at 1.7 amps (this delivering 15.3 watts). ... In the first 60 minutes of charging, the voltage stays at 9 volts while the current steps several times down to 1.3 amps"
G6 charging slow
My g6 is charging crazy slow no matter what...I use amperage app and I can only get out to draw 800mah, no matter what I plug into.(2.1a etc)...doesthis mean I should replace its battery or what?

If your screen is on, the charging current decreases to max 800mA so the battery won't overheat during charging and phone usage.
If the screen is off for longer period of time and the phone still is charging slowly, it is usually caused by warm phone or environment OR heavy tasks performing in background. If none of these conditions apply to your case then (unless you are using original charger and original cable included in the box) it might be something wrong with the phone.
I have USB port tester from AliExpress and I made some tests of charging currents and voltage on my BlitzWolf BW-S5 charger as it's QuickCharge 3.0 certified charger.
With the screen off, the phone does ramp up the voltage starting from 5V. The steps are 200mV every couple of seconds. It's absolutely in line with QuickCharge 3.0 specification BUT! the phone ramps up only to 9V and then stops. It never reached 12V - maximum QC3.0 voltage.
I did plenty of tests and the voltage always stayed at 9V.
Also the current never reached QC3.0's 9V's maximum value of 2A. It usually was around 1,5A-1,8A.
I even placed my phone in the fridge a couple of times, no result
So my opinion is G6 is QuickCharge... 2.5 compatible? Voltage stepping from QC3.0 applies to our phones but either voltage or current does not match QC3.0 maximum values that can be pushed to the phone.
Also charging with original LG charger included in the box and BlitzWolf charger takes almost the same amount of time. Sometimes LG is faster, sometimes BlitzWolf is faster.
