[Q] What charger specification is best for Lg G2?

hello;
i have just bought LG G2 (F320L), i have noticed that if i charge the phone with a charger having 1amp output specification it charges rapidly.
So the question is that what charger output specifuication is best for Lg G2 which may charge the phone rapidly but does not damage the battery.

U can use a 16a charger if u want. The charging circuits in the phone handles the input so max the phone will use is 1.6a. It's li-po cells the phone has som advance circuits handling the balance charging of the cells. Recommended is 2a charger but don't forget the cable.
If u use a chappy cheap cable it won't go above 0,3a use a premium and u whill have a 1.6a charge. 1a is to little and to slow.
The phone handles the power to optimize the charging so don't be afraid to use a powerful charger just make sure it's 5v and above 1.6a. If u bye a 1.6 the charger itself will be on max load and generate a lot of heat with could damage the charger and the phone so go with 2a and a premium cable

I'm pretty sure the post above's first reference was meant to say 1.6A and not 16a (the second reference was corrected). 16A wouldn't necessarily hurt the phone actually since current aka amperage is pulled and not pushed - the device would still only take what it needs as long as the 5VDC is solid.
Anyway, enough rudimentary electronics and electrical theory...
Any modern USB wall charger will work with the G2 without issues, obviously if you can get and use one that provides a higher level of amperage/current it will charge the G2 faster up to about 1.6A as mentioned above. The factory charger included with G2 smartphones is designed to provide 1.8A but the G2 won't necessarily pull that much - the .2A is a little headroom and the charger doesn't "stress" as much to provide the 1.6A.
Lower amperage/current chargers just mean it takes longer to charge the G2, basically. As it has a 3,000 mAh (that's 3A for the record) that basically means with a 1.6A charger attached and the device powered off and charging exclusively you'll get a full charge in just under 2 hours from a near-empty state - if there's a charge on it already then it'll charge at roughly 1% every 2-3 minutes, maybe a touch more if the G2 is powered on and charging.
Either way, again, any modern charger will be fine. Try to get at least a 1A model from whoever, and avoid really cheap ones that can't do 1A minimum. If it's a brand name charger (Apple, Samsung, LG, Motorola, BlackBerry, etc) you'll be fine.

thank u for making it clear,
is there any way to measure output of any charger?
i know its not related here but just for fun.:laugh:
currently i am charging my G2 with 1A charger but it takes so long to reach 100% charge, may be about more than 4 hours.

Actually I meant 16a.... Just get a 2a charger and not a cheap one.. Expect to pay 20$

Once I ordered a 2a charger from China.. Output was 200mah and it almost melted. 2$
U can measure how mouth the charger provide.
Easy way is to use a app in you phone. But not 100% accurate.
Hard and accurate way is to use a USB extender cable that u cut the + cable and use a ampere meter. But u have to use a high end cable for that and u don't want to cut a perfect god cable in half
So I recommend this app https://play.google.com/store/apps/details?id=com.manor.currentwidget

Charging Speed

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.

Just smh at this whole post. I want my 5 minutes back.

Thats weird, Im using my Note 7 charger on the V20 and it charge the phone completely in less that 2 hours. In my case I always drain my phone to 3% and leave it charging up to 100%. I will check again tonight to be sure.

I wouldn't drain it that low all the time unless you plan on stocking up on batteries or don't mind depleting longevity of battery quicker than usual.

Tmobile Jump on Demand ftw - I only have devices for 5-6 months tops and then get a new phone

Tested this one one when I got home.
https://www.amazon.com/gp/product/B01FCZACFA
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.

My devices go back to tmobile which then go back for refurbishment. With the V20 it's easy for them to just replace the battery.

And you really think they do?

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".

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 Nokia 6 (2018) can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

There's an 18W charger included. I believe the claims of 50% in 30 minutes are pretty accurate.

hi guys,
I have recently bought this smartphone and I have one question. When I use its own charger the default mode of charging is fast charging but I don't want always to use fast charging since it's not good for the battery life-time. Is there anyway I can do to disable fast charging?
thanks

I believe the only way is to use another charger, because this is all hardware related.

Hi people,
are there any other 3rd party chargers for nokia 6 that you would recommend.

Hi. I have just bought this phone and it was all fine. I needed another charger for work so bought a 3Rd party one. It was fine the first few times, but now when I connect it the phone automatically shuts down and will not start again. According to the tech that checked it out, the battery was completely flat.
I suspect I can only use a OEM charger. Really inconvenient.

Nokia lie about fast charge between 0 % to 50 % in 30 minutes . I tested it many time 50 minutes to charge 50 %

Not true. I have never used the OEM charger. Fast charging is tough on the battery as others have said. I have several other chargers (one came with my audio chromecast, one came with an old HTC phone, one is a no-name charger). They are rated anywhere from 1 amp to 1.9 amps. All have worked perfectly. At work I leave my phone on my desk so leaving it plugged in until charged regardless of how long it takes is no big deal. I also make sure to take it off charge once it reaches 100%. It is not good to leave it on charge when full.

More than 2 amps at 5vdc are overkill for the battery and it's causing nothing but a superfast degradation but hey we have superfast charge on a cheapster ...

I'm using an old Aukey QC2.0 charger that I bought 3 years ago for my Zenfone2, it charges quick too. Using a meter I checked that the Nokia charger is using QC3.0 and for instance can charge at 6V/2A or about whatever voltage it wants, but my QC2.0 charger is 5/9/12V only and with a meter I checked it is charging at 9V and ~1.6A. My car charger is also a QC2.0 charger and works too, on the lock screen is it written "fast charging" and yes, it does.
The chargers I use daily for 3 years now (I have the old 2.0 version but now they are 3.0 version)
https://www.amazon.com/AUKEY-Charger-Charge-Samsung-Galaxy/dp/B01BBZJ31Y
https://www.amazon.com/AUKEY-Charger-Samsung-Qualcomm-Certified/dp/B01B2BMIMS

so practically using QC 2.0 and QC 3.0 got same charging speed? so what is the advantage of using QC 3.0? can anyone give some info?

QC2.0 is something like 5V/2A, 9V/2A and 12V/1.5A, while QC3.0 voltage range is wider, something like 5V to 20V, requested by the device, it can be 6V/3A for instance. Battery management is better I guess.

Why on earth was fast charging disabled for this nexus?

They didn't disable anything - it doesn't have the Qualicom Quick Charge variant, but it does have it's own variant of a rapid charge.
Using two wall chargers I have here and a Benson certified USB-C Cable, one of the wall chargers support QC2.0 and the other QC3.0. Both charged "normally" reporting on the screen as "Charging".
Using the stock USB-C wall charger that came with my 6P, using EX Kernel and the stock kernel from January 8.1 stock ROM, both reported "Charging Rapidly". I switched kernels using EXKM and a backup of the stock Kernel to test this.
Also, I bought a Tronsmart USB-C Car Charger, and it too reports "Charging Rapidly".

Hey everyone,
So I got my nexus 3 Months ago, I just found out NOW that it is not fast charging at all. I bought a new ANKER charger and wire with it and its just charging slowly which got me really annoyed as I wasted money on it because I thought it had nothing to do with the phone at all. I did some digging around and the maker of franco kernel found out that bloody google disabled the bloody fast charging on the 6P?! What kind of solution is that? I mean they could of at least gave us options on whether to disable or enable it in the phone. Is there ANY way to get fast charging enabled on this phone?

Nexus 6p just charges at a higher amperage then most average phones. As long as you use a charger with 5V/3A you should get charging rapidly. Just remember as the battery percentage increases the amps get lower. Use an app like ampere to make sure your getting close to 3000mA. I think the highest charge I seen on the stock plug was like 2800mA.

Well I bought an ANKER Charger and usb cable with it which definitely says it is fast charging compatible. When it comes to charging my phone I got a small text on my lock screen showing me how much charge there is going to the phone while charging. The average charging mAh is 1,400 and the voltage is 4.3V. I am pretty sure that it has reached a higher charge rate....I'll have to keep an eye on it. Do you think thats an acceptable charging rate?

It's not just about amperage, because some of their chargers are a whopping 8A - https://www.anker.com/ca/products/108/203/Wall-Chargers
Anker doesn't support the variant of rapid charging that the 6P accepts, therefore it only will negotiate down to a normal "charging" rate, which IIRC is exactly what you're getting.

Noice yeah Amazon is good that way!! ?

I'm having this problem too. I used to be able to rapid charge using anker usb c to usb c but now it just seems to charge normally not rapid charge.
Anyone know of a fix, let me know.
Thanks

Using Samsung 5V-2A FAST CHARGER WITH G6...?

Using s8 fast charger it is rated as 5v , 2a im worried as is dont have lg original charger which supports 1.8a(fastcharge). My phone also got hot on samsung adapter . Should i buy original or its nothing to worry about. Kindly need advice.

AFAIK, there will be no difference. The chip controls how much energy is delivered to the battery, and even if you use a 3a charger, the phone itself will limit the maximum energy delivered so it doesn't affect battery.
It's normal that the battery gets hot on fast charge (even in normal charge) Just try to avoid using the phone or charging in a hot environment so the battery doesn't go further than ~40°C more or less.

The original one is 9V 1.8A so there won't be any problems with the Samsung one.
