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?
I have tried multiple 2.0 chargers (OEM and Stalion), and it seems my phone always wants to Fast Charge, regardless of disabling it under Settings. Sometimes it will honor the setting, but most of the time not.
Anybody else have this issue? I am aware I can just use a regular charger and it will force cell to charge normal rate, but did not know if this was maybe firmware related. I am on PB5.
Do you mean QuickCharge 3.0 charger? Our phones can only do up to QC 2.0 (9V), which is still a very rapid charge. QC 3.0 is very similar to QC 2.0 but charges in more fine grain steps so it can charge even faster.
I don't have the answer to your question though. Mine seems to be doing fine when I choose not to use QC feature. This was with PB5. I'm now on the latest firmware and didn't try using the normal speed charging. It's just too slow, but I would use a regular 5V charging if I do it overnight.
I just keep a fan next to where I charge my phone (with QC 2.0) and use that fan to cool the phone. It keeps the battery temperature in check.

Thanks for replying. I forgot that S7E OEM charger is only 2.0. Thanks for clarification. I have only 2.0 chargers, I just brainfarted.
The issue I have is on both 2.0 OEM and Stalion chargers, so it points to a cell issue. I charge mine overnight normally, so I don't really need the QuickCharge capabilities, plus batteries normally last longer when getting a slower charge - not sure if that applies to S7E as well. Plus if a battery temp can be lowered charging one method compared to QuickCharge, I would think the battery life should be longer. That's my opinion, though it would be nice to know for certain.
Good idea on fan as I am sure every little bit counts Hopefully someone can chime in that can try QC 2.0 OEM charger with QuickCharge disabled a few times, as it works here and there but normally does not honor the Disabled setting.

Battery lasting longer - you mean the life of the battery, or hours per charge? I don't think using 9V or 5V has any effect on how full it really fills it up. As long as you keep it long enough after it shows 100%. I think of it like filling up gas for your car, quick charge just fills it up quicker and it may bubble but if you do it long enough it should have the same amount fuel in the tank. If you have a USB volt-amp meter you'll notice once the phone reaches 80% it slows down the charge current.
I know some believe that charging slowly will increase the life of the battery but how slow is slow enough, I don't know. Some believe too slow might cause crystallization. I don't know which would apply, but I'm pretty sure the heat will kill the battery.
At one point I even used a 0.8A charger which is the weakest one I can find in my collection. With that there's almost no heat but charges really slow. lol.
If you are charging overnight why not just get an extra normal charger that doesn't have the QC capability? I thought everyone has enough 5V standard USB charges laying around nowadays, from Apple products and all the past phones...
Keep the OEM fast charger for emergencies or travel or on the go or in the car. Because when you are traveling you'll want to charge as quickly as you can even though it could cook the battery a little bit.
Sorry I can't be any help and I'm really not answering to your original question.
No, you made good points man. Really appreciate it
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Redmi Note 5 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
2 Hour With Stock Charger
I didn't completely check the ratings and time but stock charger DOES NOT fast charge this phone. as the Stock Charger isnt QC2.0 Supported. However this mobile does support QC2.0 but you'll have to test QC2.0 Charger 1st. Not all QC2.0 Chargers work on this mobile. Its a little picky. So go to a shop check QC2.0 Chargers on your mobile. when you get circle Sign on notification bar along side battery then it means that device is fast charging. if not then there will be no circle around the charging sign (Flash sign)
also idt this mobile supports QC3.0 but i dont have tools to check amps volts of charger.
Lenovo's original QC3.0 charger doesnt work on this phone. I've tested. but Motorola's QC3.0 Charger works fine.
my rn5 pro , takes apporx 3 hours to charge completely!
So far I'm a bit slow, a little bit more than 3 hours to completely charge the phone. Might have something to do with the cable.
My current charging setup:
- ANKER 5 port 40W
- a docomo USB cable
Planning to buy a proper 20AWG usb cable and a QC2.0 adapter.
I just bought a Letv charger which supported qc3.0 for about 4$ on taobao
I'm currently on the 9.5.11 build and it takes about 4-5 hours to completely charge the device using stock charger, And it took about 2-3 hours while on 9.2 build.
I wonder if the Mi QC 3.0 based charger would improve the situation for us?

Slow charge is a known bug in 9.5.11 build. Wait for an update or change ROM
13,2W for me
I recieved 9.2.13 update yesterday and have been noticing significant boost to charging speeds since then...yet to fully charge from 0 so can't comment on total time but as per Ampere, charging speeds are in range of 1500 to 1700 mah
1000 mA max with 5v 2amp and Work Normal Speed with Stock Charger
Approximately 2 hour for charge phone
I use the app Ampere (free in Playstore) to measure power input and with a normal charger (non QC) it shows up to 1600 mAh charging amount and from almost 0 to 100% it is taking 2,5 hours. One question: is there a way to tell if QuickCharge is active?
@Kusie
Look on your"s phone status bar. With normal charging there is thunder icon next to the battery. With QC active, thunder in in circle as far as I remember. Info about active QC should be also displayed in the bottom of your lockscreen
Sent from my flo using XDA Labs
Using my usb inline meter, i'm getting ~6.5v and ~2.2A, with a Tronsmart usb cable and QC 3.0 Truro charger, screen off and about 44% remaining on battery. Will try when the battery is lower some other time.
takes around 2hours to charge 100% using stock charger..

I have no idea why would you do that... But read reviews, no matter what kind of charger you use, this phone only supports qc 2.0 version. From 0 to 100, in 1 hour, you only get like 55%, and in the end it slows down even more, so yes, impossible to fully charge in 1.5h, TECHNICALLY IMPOSSIBLE. You are either lying, or mixed times and got confused. Judging by technical parameters, the best this phone can do should be around 2hours from 0 to 100.

I just posted above that I was able to get QC 3.0 charging rates. Approximately 2.2A (fluctuates +/- 0.1A) and 6.6v (fluctuates +/- 0.2v) using a QC 3.0 charger and Tronsmart cable. Measured using an inline meter, not software.

I have done some testing.
With QC 2.0 (my old Motorola Turbo charge 15) I charge phone from 20% to 90% with rate 65%/hour (1 hour and 10 minutes time)
With QC 3.0 (charger and cable from original Chinese packaging) I charge phone form 30% to 87% with rate 95%/hour (40 minutes)
I think this scenario is common for most users when they need to charge phone in hurry.
Later I will add also charging rate for quick wireless charger included in box and maybe also some QC 4.0+ if I get my hands on some.
In my case, I bought a PD3.0 charger from Aukey and my Mi Mix 3 is charging from 0% to 100% in 1h08 !
In fact after a few research I found that Power Delivery Technology is compatible with Qualcomm Quick Charge because Quick charge is working with Power Delivery and add a few security technology, but power delivery already have some.
Nevermind, I tested it and indeed My PD3.0 charger (max 15V and 3A) with a anker cable wich support up to 5A is working faster than the QC3 charger !
I suppose a QC4.0 should be better, but for now I think PD3.0 is the best solution !
I second @romain1672...I've converted all my chargers to USB-PD since I've divested from non-USB-C devices and my Mi Mix 3 flies with them.
I believe the wireless charging is relatively slow, think one review said three hours for full charge? But that's expected to be honest.
I've heard it said that slow charging is better for battery life, so in effect, wouldn't the wireless charger be better than cabled, if you're not pressed for time?
It took me exactly 1h45 to charge from 17% to 100% with the wireless charger. It's pretty fast for a wireless charger, but the only issue is that it heats lot of more than wired, and i read somewhere that heat isn't good for battery health.
Hi guys, I just bought the Razer Phone charger (it's the only one I could get quickly with Quick Charge 4.0+ in the UK). Not the most scientific of tests, but it went from 30% to 87% in 30 mins. I tested from 30% again today with a Quick Charge 3 charger and in 30 minutes it made it to 80%.
Sorry I didn't run from 0-100%, I can probably test that more easily this weekend if people are interested?
Fast enough that for the first time since owning a smart phone I never have to think about looking for a charge, even when travelling.
Does anyone know of any wireless chargers/charging stands that charge the mix 3 as fast as the included one? I've tried a couple I had with previous phones and they just charge so much slower
This charger is becoming annoying.
I place my phone on the puck by my bed. Sometimes, before falling asleep, I hear the sound indicating charge stopping.
Then, in the morning I find my phone has moved off the puck. And it is not me! The phone slips away if not perfectly aligned centrally on the puck. It is not surprising as the induction forces between the puck and phone will be opposing but the manufacturer should have spotted this and made the puck/phone with more friction between them.

Bro, I use my brothers Samsung Wireless Charger "EP-NG930" from his S8. Google it to see it. I can't post a pic of it since I leave it in the office but underneath it is rated at 9V 1.67A (15W)
I must say it charges pretty much the same, if not, faster than the included one since it has a built-in noiseless fan behind the coils
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.
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.

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.

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.
