Hey all, haven't been able to find an answer for this. So I'll open a new thread. Now the question. The phone seems to take a long time to charge. Is it possible for me to use my Note 4's quick charger or can anyone recomend a faster charger for this phone? Charging it with Note 4's 2a charger wont damage the battery? Thank you.
I use a 2.1 out and it charges in about an hour and a half
Charging isn't fast and it seems that if the phone gets warm, it draws less power then too - so on a warm day, it can feel like it's taking years.
Would have been nice to have had wireless charging support and/or turbo charging, but alas not.

Doesn't the phone support quick charging? But Huawei haven't bundled the appropriate charger?
Doesn't appear to. I've got a Qualcomm Quick Charge 2.0 adapter and it doesn't seem any faster, nor say fast charging.
There's a quirk, when the battery shows 100% it actually still keep charging for another 30 minutes. All tests showed that it took 3hours+ to fully charge it. So quick charge my ass.
So just to update, I have tried charging it with note 4's fast charger and it charges the phone from 20 to 100% in about an hour and a half. Which imo isn't that bad. With the included charger, it took me around 2 and a half hours... Huawei really should have included a charger with higher amp, 1 is way to low.

It's sadly very common for phones to ship with poor chargers (1A and even lower), but then again - some phones these days come with NO charging adapter, assuming you'll have a ton of them anyway.
I use a 2.1A 5V charger, but I've tried the faster ones (that can output 9V) and it doesn't speed things up, so while it can charge faster with a better PSU, it won't ever charge as quick as many other flagships. Mind you, has the G4 been given full support yet? Likewise, the Z3 is down as supporting Quick Charge 2.0 on Qualcomm's website, but then turns out to be only some variants. Makes me wonder if the Z3+ supports it in every guise.
Not sure what the reasoning is for devices that could support faster charging not actually allowing it, especially if the manufacturer could profit from selling faster chargers separately.

I read an article about Huawei declining fast-charge for "battery-purposes" so it can have a longer life cycle. But i think Huawei made an exception about the Huawei Honor 7.
I had an Samsung before and never had problems with fast-charging whatsoever.
My P8 was full in about 2 hours with an 2.1 A charger, while my Samsung Galaxy Mega 6.3 took 1,5 hours.
the screenshoot took from Huawei P8 & P8 Max Launching Event 2015 said that p8 has quick charge at min 21.30 but they didnt talk about that in the event

Here's a quick charger for the Huawei P8 : http://www.amazon.com/Adaptive-Charger-Charging-voltages-charging/dp/9713256832
I did not buy it, but it says it charges at 9V 2.1A

I think this adaptor isn't safe to p8max.. I will try another charger but only 5v with higher amp that will be safe for sure
Now i charge with stock from 3%to100% in about 2.5 h and the phone didn't tell me to remove charger for more half ahour!!

I dont know, its 9V 2.1A, so it is quick charge. But i dont know if it is for MAX. I can charge fast. maybe 1.5h/2h?
In a review site someone claiming confidently that the G4P does support turbo charging despite no mention of this in specs. Does anyone have the G4P and a turbo charger can do a test?

Well, I don't think Motorola really advertised "Turbo" charging for G4 Play.
They advertised something else. Here's what it says on their site:
Moto G Play works with the 10W rapid charger (charger in-box), which gives you 5 hours of battery life in just 15 minutes of charging.

The fact they package with a low spec charger in a $150 box is not a concern. I own dual and quad chargers I carry for phone tablet BT etc.
The question is a specific charger able to charge faster? I looked at the one supplied and it seemed to imply a 5V input then as much Amp as phone can take, which is usually about 1-1.5A til 85%.
Turbo, is I think like QC, it increases the voltage at low battery charge, such a charger would show say 12V or 9V output.
Is there any good charging app to watch what the phone is doing? I have iSmart, QC 2.0 and QC 3.0 devices I can test on.

The way I find best is to not use the phone and use a stopwatch and measure at 15m intervals.
It does take days to be ready with a low charge condition.
App I have used is Ampere but I find it unreliable as the act of using the phone means heat throttling down the charging speed, if you don't use the phone then Ampere sleeps and doesn't monitor.
From what I understand, it does support it but you have to buy an additional charger.
It definitely does some kind of fast charging because my Anker Powercore+ 10,050mAh power block charges it incredibly fast. I don't know what other charging methods the Anker does beyond qc2.0 since I have had the Anker less than 12 hours.

If this behaves like osprey (which I expect - I haven't yet examined the kernel), the hardware doesn't support the Qualcomm high voltage quick charging, but it does support regular charging up to 800 mA. The weak 550 mA charger bundled with the North American variants will not make the most of it, but a 1A charger or better should get full charging performance.

So does this mean the 2.0 A bundled chargers are bottlenecked, like they support 2.0 A and the phone supports only till 800 mA...am I thinking correct?
My XT1607 US unlocked retail version came with a 5V 550mA labeled charge plug. I used a cable and power plug from another device that rated at 5.2V and 1.35A and it drew about 1.4A from it. Then I dug out another USB adapter rated 5.3V, 2A . It consumed 1.78A and it was 80% charged at the time. That would make for some much faster charging than the original plug. Wouldn't matter much if you just plug it in overnight to charge.
Anyone confirm if the it supports QC 2.0? Only thing wrong e phone is slow charge from supplied.

I have used the turbo charger supplied with Moto G3 Turbo and it charges much faster than the one supplied in box. So yes it supports turbocharging but you need to get the charger elsewhere.

Logic fail. The supplied charge is feeble like 0.5A so anything like 1A or 2A is better.
That does NOT mean turbo is supported.
When I plug my G4 Play into my Anker 4 port power supply and then into a kilowatt meter, it draws 10 watts. If we work it backwards, that's 5v and 2 amps (however, need to account for line loss, transformer loss and other losses). A watt is a watt, doesn't matter what the voltage or amperage is, as W = V x A.
This phone charges much quicker than my old Moto G second gen, which would take close to 2 hours to fully recharge. I have had this phone recharge in as little as an hour from around 30%. It's a shame that the SD 410 chip supports QC 2.0 but Motorola didn't enable it. It seems to have QC 1.0 (which is the 10 watt, 5v @ 2amp rating).

Regular USB is 2A 5V 10W.
https://en.m.wikipedia.org/wiki/USB
Standard USB 2.0 is 500mA
USB 3.0 is 900mA
There is a new subset standard called USB power delivery, it's used for newer devices.
Quick charge 1.0 was 2 amp at 5v.
There's a little more info here. https://www.easyacc.com/media-center/quick-charge-3-0-vs-2-0-vs-1-0/
These phones charging at 2 amps is technically quick charge, whether it's the 1.0 revision or not is really down to licensing and stuff. They don't charge at 2.0 speeds unfortunately. Even though the chipset supports it.
If yes, Then let me know which brand of charger should i buy!
No.
I think it only supports QC 2.0, though the QC 2.0 charger does not come out of the box. But imo, who needs fast charging when the battery life can last up to 2-3 days with this phone.
in it's specs sheet in gsmarena quick charge 3.0 is listed. That's why i asked.
anyway, what's the best quick charge 2.0 charger out there? and will that charge the device faster than the original charger?

The 625 snapdragon processor does support Quick Charge 3.0, but Xiaomi prohibits using it i guess to cut cost, i know some user who try to use QC 3.0 on this phone but it doesn't work, to be honest i'm also not sure about QC 2.0, my advice is you should try testing it first by borrowing QC 2.0 charger with some of your friends/relatives that has QC 2.0 charger before attempting to buy one.

No QC 2.0 support for me, tested with new xiaomi powerbank 10000mAh, ampere show max usb current 500 mAh instead of 2000 mAh. However from measurement I can get 1700-2000mAh so still charging fast enough.
Redmi 4 supports Fast Charging (i.e. about 2A), not any form of Quick Charge. The chipset supports it, but as Xiaomi have decided not to pay Qualcomm the royalties they charge for QC, it's disabled at a low level in the phone. It might be possible to enable it via custom kernel, but I don't think it's been done yet if so.

you mean that from the measurement you're getting a CURRENT reading of 1.700 to 2.000 Amps, right? Because mAh is the capacity measurement while A or mA is the current measurement?
To be on topic, the hardware inside (global version - snapdragon) and the battery support QC v1-3 specs but quickcharge is disabled.
The phone will charge at 1.8A or 1800 mA for about 10 minutes between 20% and 55%. battery capacity.
the current raise up while you changed to a qc 3.0 adapter.

CURRENT WILL NOT RAISE ABOVE 2A by now. ONLY VOLTAGE WILL BE INCREASE, but with decreasing current.
I tested a bit :
with QC 3 compactible Aukey PA-T16 charger, Ampere shows 2030mA
with Anker 40W 5 port charger Ampere shows 1830mA.
I have a Redmi 4 (standard edition) and I also have a USB Ammeter/Voltmeter which I can use to measure actual voltage and current flow into the device.
Using a standard 2A charger, the device accepts 4.9-5.1v (average 5.0v) at 1.5A (1500ma), and rarely exceeds this due to the voltage drop of the charger circuit /transformer in the wall plug.
Using a Quick Charge 3.0 charger (Capable of 5v, 9v, 12v and dynamically 5v-12v for QC3.0), I was able to charge the Redmi 4 at 6.2v/2.1A. The peak voltage was 6.24V and peak current 2.4A (momentary).
The Redmi 4 will charge at 6.2v and 2.1A with a Quick Charge 3.0 compatible charger when the battery is totally flat. As with all batteries the current slowly decreases as the internal resistance of the battery increases as it charges.
This is 13 Watts of power, 1.7 times higher than the 7.5 watts provided by the included '2A' charger. Thus, while it does not officially have QC3.0 capability, the device is still able to utilise a slight boost from the chipset's compatibility with higher voltages. Realistically, this means you could cut down on the charge time by around 1/3, and even moreso when charging from, for example, 0%-30%.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V30 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
a little bit hot
sadly after 1 year, the charger that came with the phone is dead LG is unwilling to replace one for me because warranty for accessories is only 6 months. so disappointed with LG in terms of quality of materials as well as customer service. Customer service wise, I was disappointed because they did not read my email clearly and sent me an automated reply. wasted my time going to LG service centre...

If you mean the LG wall charger, luckily there are very inexpensive QuickCharge 3.0 replacements. Some even come with 10ft charging cord included; useful for when wall outlet is a few feet away.
There's also QuickCharge 3.0 dual port car chargers.

My v30 charges faster than my v40?!?
Had bout 2% battery left when I plugged in my v30 to charge on a QC 3.0 charger, noticed it started at 2970mA. It's now just over 10 mins into it, I'm at 40%, it's still sucking in juice at 2865mA, see screenshot.
Accubattery says in 13 mins I'll have 80% and in 20 mins, it'll be fully charged.
Keep in mind, according to Accubattery, I only have 70% of the original capacity left 2300mAh vs the original 3300mAh (2nd screenshot) so that's why it seems faster than usual.
It's clear my battery's dying a slow death, but least it charges up fast, I can't get over 1900mA on my v40, no matter what charger Im using?! It's so weird?!
Anyone knows if the original charger is "intelligent", meaning it cuts power/charging when battery is fully charged?

Generally speaking, it's not the charger that's "intelligent" but rather the phone. It stops powering the charge circuit when the battery is full. Yes, that is the case with the V30...
The phone's QC chip also allows it to charge at higher rates, if the charger supports it (9V and higher charge voltages). Again, that's in the phone primarily, but in this case the charger needs to comply as well, of course.
Thanks, mate. Truly appreciated
1% per minute with a QC 3.0 charger and cable
So, I have finally learned what in my charger makes it fast. It uses the 5V and not the 9V, not sure why there's a 9V if phones use a 5V but I learned that the more amps the faster the charging. Like I currently have a ZTE 1.5A charger and a friend has a 4A dash charger for their OP3. Mine takes over an hour and their's takes a hour at most they claim. So if the V20 supports 3.0 charging, what's the most amps I can use in a charger to get the fastest charging possible? Would it be unsafe if I went to some extreme amount, like would it make my phone over charge and blow up or something?
The total power charged (watts) = voltage x amperage. So its a function of both volts and amps. For the fastest charging get a charger that supports qc3. This is standard that includes both how fast to charge and a signature that the phone and charger support qc3 to actually use the faster charging.
If you get a charger that doesn't support quick charge but some other standard the phone and charger will see that they don't support that other charging standard and charge at a safe slow rate.
The V20 does not support QuickCharge 3.0, that needs to be clear from the start because it causes a lot of confusion. The Snapdragon 820 does have support for the QC 3.0 standard, but LG chose for some reason NOT to support it. What the V20 does support is USB-PD aka Power Delivery which is similar to QC 3.0 in how it operates but it is NOT QC 3.0 (but the V20 does support QC 2.0 without issues with the stock charger).
USB-PD works like QC 3.0 in the sense that it does the charging in a different way that keeps the cells cooler during the charging process and doesn't cause the heat buildup that QC 2.0 causes. The factory LG V20 charger supports QC 2.0 and if you go into the hidden menu (*#546368*<3-digit model number>#, might not work on every variant) and then SVC Menu - Battery Test - Battery Info - select the Enable Log button - check the box for Battery Log Save On/Off and it will then show the relevant info. Once you see the information display, plug in whatever charger you wish and then wait and see what it shows for High Voltage parameter.
If it's QuickCharge it will show the version being used - the stock V20 charger shows me QC2 so that's QuickCharge 2.0. I have a Samsung QC 3.0 compatible charger and when that's attached it shows USB-DCP which from what I understand is Samsung's modified variant of USB-PD but that could be wrong. I did some quick research and found this so it could be limiting the charging to 1.5A which is perfectly fine with me):
Dedicated charging port (DCP) BC1.1 describes power sources like wall warts and auto adapters that do not enumerate so that charging can occur with no digital communication at all. DCPs can supply up to 1.5A and are identified by a short between D+ to D-. This allows the creation of DCP "wall warts" that feature a USB mini or micro receptacle instead of a permanently attached wire with a barrel or customized connector. Such adapters allow any USB cable (with the correct plugs) to be used for charging.

That was taken from this page:
https://www.maximintegrated.com/en/app-notes/index.mvp/id/4803
My V20, using the stock Samsung 2A charger that I always use (because I don't like to quick charge my batteries, I don't trust it in any form and I still think it's damaging the cells but that's my own personal opinion on quick charging overall), can go from 15% to 85% (I use AccuBattery set to 85% and it alerts me when it hits that point so I can unplug, this increases the overall lifespan of the cell I'm using as measured in years not per-charge) in about 55 minutes to 1 hour depending on whether I'm still using the device or letting it charge screen off. That's using a plain old vanilla 2 amp capable charger and when I check the charging current sometimes it'll actually show 2.2 amps (2200+ miliamps) so I'm perfectly happy with that situation.
I've read reports from owners of Pixel USB chargers and when they use them with their V20 smartphones and look at the battery info in the hidden menu it will show USB-PD so I might have to get one of those sometime and see how it goes.
Suffice to say, 55 minutes for a 15% to 85% charge for me is fast enough and the battery still stays pretty cool overall. USB-PD is probably the best tech we'll be able to make use of with the V20. I've read that the V30 does fully support QC 3.0 without issues and the the stock V30 charger is QC 3.0 compliant. The new V40 is QC 4.0 ready but I don't know at this moment whether or not the actual stock charger handles it but again, the QC 4.0 support is handled by the SoC and it remains to be seen if LG allows it or forces it to QC 3.0/USB-PD operation. Guess I need to do some research into that aspect of the V40 too.

The V20 can support QC 3 with a custom kernel, for example with mk2000 oreo 1.1 beta with a qc3 3 charger it indicates HVDCP_3 (HVDCP is one of the important parts of quick charge)
I've been using exclusively pd or qc3 chargers with my v20 and both properly work, verified with a usb power meter. Qc3 does the little 200mv adjustments as expected. Although to be fair i do run mk2000

Have always doubted whether it was QC 2 or 3 but the log shows QC2.0TA in the service menu. Voltages measured by an inline meter are closer to 9V and around 1.3A (only with screen off) which suggests QC2. Power in shoots up to 15W initially and then drops to 13W and then 11 something W.
QC3 would be closer to 7V something with a higher amp input.. That's what the QC3 power bank used to charge the V20 accepts when charging itself.
This is stock btw, not rooted nor using any roms.

I found this interesting and hooked up my 100W laptop usb c charger to the phone and then use a usbc inline meter and found it did quick charge. At the same rate as Qc2. The meter read 8.91V @1.5A . This is surprising as i'd have thought usbc operates at 5V and a higher amperage.
When i looked at battery test screen from the service menu, the item for High voltage TA status reads as OFF. Yet my plugable usb c inline meter records around 13.5W going in with screen off. The voltage was 8.91V 1.5A. That's not USB-PD afaik, which should have said 5 V and a higher current draw. My laptop charger does not do Qualcom quick charge at all, So i'm not sure what is going on here.
I've been wary of using my laptop charger to charge the phone as i'd read an early report that some people had a bootloop problem and it was caused by USB PD chargers.

I did some quick research and found this so it could be limiting the charging to 1.5A which is perfectly fine with me):

Interesting, when i hook up a ravpower power bank that is also QC3 comparible i still see QC2. It charges no faster than the stock charger LG includes in the box
I've read reports from owners of Pixel USB chargers and when they use them with their V20 smartphones and look at the battery info in the hidden menu it will show USB-PD so I might have to get one of those sometime and see how it goes.

Not in my case with a laptop charger, it just reads as OFF.. Do you remember where you read this maybe a link.
However when i use the laptop charger to usb C PD charge my power bank, the meter reads 4.89V 2.77A. That is a usb c PD charge. These are not the figures i get when using the laptop charger with the V20 as indicated above.
USB-PD is probably the best tech we'll be able to make use of with the V20. I've read that the V30 does fully support QC 3.0 without issues and the the stock V30 charger is QC 3.0 compliant. The new V40 is QC 4.0 ready but I don't know at this moment whether or not the actual stock charger handles it but again, the QC 4.0 support is handled by the SoC and it remains to be seen if LG allows it or forces it to QC 3.0/USB-PD operation. Guess I need to do some research into that aspect of the V40 too.

I have mixed views about USB-PD and its suitability for phones. Laptops have larger cooling areas and so USB PD is fine with them. My laptop has a 100W charger and its charging as i type this and i don't find the laptop gets warm at all. The history with the 6P & First pixel showed people with battery problems and having to replace the battery shortly after a year. Particularly with the 6P. Not heard any problems with the second gen pixel as yet. Maybe its still too early. But even with qualcom quick charge and i use it all the time there should not be any problems with battery after a mere year.
Having said all that in the last post I made, a friend gave me a Samsung EP-TA20JBE charger last night, go figure. It's the first Samsung "fast charger" that I've had and I decided to plug it into my V20 and see what it showed. I know that if you use the Pixel chargers the battery info in the service menu will show USB_PD meaning it's communicating and charging using the Power Delivery standard. My regular Samsung 2A charger - plain old vanilla non-QC compatible straight 2A charger - shows USB_DCP when charging my V20 so that's a known thing; there is no QC support, no PD support, nothing but just pure current provided as requested.
Here's the funny thing:
The Samsung EP-TA20JBE apparently is a QC 3.0 compatible charger, but since it's made by Samsung what I see under the battery info is USB_HVDCP which I've never seen before. So I did research into the USB_HVDCP meaning and of course the HV means High Voltage.
What I discovered is that if you're using a true Qualcomm compliant QuickCharge 3.0 device with a true Qualcomm compliant QuickCharge 3.0 charger, your device should report it's getting QC3.0 under the battery info but that's where the fun begins because non-compliant hardware will just show "USB_HVDCP. Of course, because this is not an LG charger and the sense and communication stuff is not from them, it's falling back to Samsung's version of QC3.0 protocols - but what I discovered is that in such instances it's actually Qualcomm QuickCharge 3.0 in effect, it's just that on non-compliant chargers Qualcomm detects the charging protocol as USB_HVDCP.
So, I ran my V20 down to about 15% using a battery app that forces the device to use nearly 100% of the CPU, that took the better part of 45 minutes or so, and when the phone beeped to alert me it needed charging I stopped the battery rundown app, let the phone sit for about 15 minutes idle so it would cool down, then I plugged in the Samsung USB charger I picked up last night (using my Monoprice 26 gauge USB-C charging cable).
Normally if I charge the device using that Samsung vanilla 2A charger from 15% it will cause my V20 to get warm on the backside because it's pulling the full 2A from the charger and of course it'll get warm. It also takes roughly 55 minutes to about 1 hour solid to go from 15% to 85%, and the phone will stay warm till about 65% when the current pull changes to something lower, maybe 1.5A, and it continues to decline as the actual charge increases and of course the V20 cools down to various degrees (pun intended) as the current pull decreases.
But here's what I noticed using this Samsung USB charger:
I watched the charging indicator (screen off, I use AccuBattery which shows me the current battery percentage on the V20's second screen) and it was literally going up 1% every 35-40 seconds which I had never seen before, all the way to 85%. My V20 remained basically cool to the touch from the moment I plugged in that charger to the time AccuBattery alerted me about the 85% cap - that's what I have it set for to ensure I get a longer lifespan (measured in years) from the OEM LG cell I bought back in August, manufactured in Nov 2017 by the date on the battery.
So, I'm not sure what this all means but based on what I read about Qualcomm and how their chargers ID themselves, if you see USB_HVDCP that is QuickCharge 3.0 under the battery info in the service menu - it's not Power Delivery because the Samsung charger doesn't apparently support that protocol (but I'm not 100% sure on that one).
It's actually honest-to-goodness QuickCharge 3.0, according to the info I read yesterday afternoon, so while I'm still not 100% sure on the protocols or the various naming conventions like USB_PD, USB_DCP, USB_HVDCP, etc (I mean I know what they stand for, sure) and how the V20 identifies the charging protocols and usage, what I can for certain is that for the first time since I've owned my V20, I can charge it with this Samsung USB charger and never feel it get warm at all so for me that's a huge positive. Li-Ion batteries HATE heat buildup, that'll kill their effective lifespan (again measured in years) more than most anything else.
All the vanilla 2A or 1.8A chargers I have cause the phone to heat up during the charging process. I have a Motorola "TURBO" 25 watt QuickCharge 2.0 compatible microUSB charger that I used for testing purposes with a microUSB-to-USB-C adapter and under battery info that identifies as USB_DCP so that's QuickCharge 2.0 (which that particular charger is designed for) and the battery heats up when I use it. This new Samsung charger I just got last night, charges just as fast if not faster and there is NO heat buildup whatsoever that I could detect so, yep, QuickCharge 3.0 even if it's not identifying as QC3.0 under the battery info.
I suppose what I said earlier is now considered moot: the V20 DOES support QuickCharge 3.0, just not with the stock LG charger because it's not a QC 3.0 charger to begin with.
So, yeah, I guess I'll be using this Samsung charger from now on.

Plain USB_HVDCP is quickcharge 2.0, when its 3 it shows as USB_HVDCP_3 (if you use a custom kernel like mk2000 and a qc3 charger its possible)
What made me think the V20 uses QC3 is the inline meter i used with it said so. This btw is from the stock charger too. But the voltages do not convince me
The voltage between qc2 and 3 are pretty much the same, but 3 has more levels in between the max and min voltage so less energy is wasted.
They're not the same. I remember a post from the HTC 10 forum and that phone comes with a QC3 certified charger and the volts were in the 7 range with higher amps. Which btw is the same as when my ravpower power bank charges with a QC3 compliant but not certified charger
So we still don't have anything absolutely concrete, great.
But as I said, with a QC 2.0 charger (the Motorola TURBO one) my V20 gets quite warm from 15% to 85%.
With this Samsung QC 3.0 charger, it doesn't get noticeably warm to any significant amount from 15% to 85% AND it gets charged faster.
So I have no idea and really just figured "OK, whatever, it charges faster and cooler, I'll use it..." and that's that.
