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 LG G5 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Great Charging
This is the first phone I have had that would actually increase the charge significantly while navigating using google maps in the daylight. And it increases pretty fast.

My Anker QuickCharge 3.0 charger got my G5 from 0 to 100% in ~75 minutes while on. The same charger port got my spare battery in the cradle fro 0 to 100% in ~3 hours (it only pulled 5V).
After lunch today, I plugged it into a USB 3.0 port on my Lenovo T430, and it got from 60 to 100% in under 30 minutes while pulling over 1.2 amps (way above spec).
I'm happily impressed!

Could be better? Not close to the G4

That's simply not possible unless you are using a non QC 3.0 charger or bad lead.

Well i aint going to get in to an argument but 30+ hours on my G4 and 20+ hours on my G5? I think i might have a point?

I'm loving the charging speed. It's like night and day compared to the M9 I used to own.

Doesn't seem much faster than speed charge 2.0 at all to me

Remember the G4 had a bigger battery so its only obvious the G4 last longer. But luckily we can buy multiple extra batteries :good:

As has been discussed elsewhere, QC 3.0 doesn't boost speed much if at all over 2.0. Instead it provides a continuous range of charging voltages (or amps? or whatever) so that it can charge at just the right rate. This should heat the battery less and (in theory, no idea how true/noticeable this will be after a year of use) wear down the battery less because of it.

Screen off = no difference in speed
Try with screen on then 3.0 is 2-3x as fast as 2.0
This has made a massive difference in the car when my screen stays on.
3.0 charges at a solid 1A with screen on as oppose to 2.0 that only musters 0.3-0.6A depending on phone temperature. ?

just throwing this in.
acording to Benson Leung LG G5 is not usb type c compliant when it comes to charging.
has anyone here tried charging the G5 using a true usb type c fast charger? i wonder what the outcome might be.
i'll be sad if i have to buy separate chargers just for this phone. (in case i get any true usb type c devices in future i mean)

Qualcomm's Quick Charge goes outside the USB-C spec in order to be able to charge compatible Quick Charge devices faster (higher voltages when possible).
Dose this meet the USB-C spec, no... Would I be concerned about it, Not if I'm using a reputable QC charger and USB-C cable.
Happy fast charging....

I'll be commenting on these cables and QC3.0 charging on my battery charging thread once I have more data. I have 2 QC3.0 USB wall chargers that I'm collecting data on now. These both have USB-A ports, so they need cable adapters.
But yes, early SPOILER @GottZ: The USB-C compliant cables (USB-A to USB-C) with the resistor limit the benefit of QC3 over QC2. But @stuart0001 does have a point with charging with the screen on.

I look forward to your findings.
After further experimentation, QC 2.0 will hit 1A with screen on when below 32deg. So I've found when screen on:
QC 2.0
<32 = 1A
32-35 = 0.6A
35-42 = 0.3A
>42 =? (I haven't tested yet)
QC 3.0 maintains 1A, certainly upto 42. Again, I've not tested higher than that.
This is all with the cable that came with the phone.

when talking about QC 2/3 you should also mention volt or just combine volts and amps to watts
just talking about amps is like saying A: has 2 inches Ampere and B: has 3 inches Ampere

Preview, Choetech quick charge 3.0 accessories

Hi All,
Got a car charger and multi port charger coming from choetech, I've used their stuff in the past and they are up there with anker as 3rd part cable companies go.
heres an early preview of them, They are looking for beta testers so you can sign up here: http://www.choetech.com/Support-review.html
Be interesting to see what these are like with the htc 10, i will let everyone know more once i receive the items.

@Phil750123, Thanks for sharing this information, I'll be glad to test the car charger!

I actually have the qc3 wall charger. So far it's charging pretty fast on my s7. Agree with other posters that the quality seems really good. Will know how it compares to stock when I get the HTC 10.

Yeah their quality is great. They were the first to come out with a good USB type C wall charger for the Nexus 6p

They're just a little bit logo happy.
RoHS eh idk. Fake CE.. And don't even get me started on that FCC logo.. Someone needs to tell them who/what FCC is..
The Federal Communications Commission (FCC) regulates interstate and international communications by radio, television, wire, satellite and cable.

Why on earth would a charger need that..
To me they just look like another chinese manufacturer.
Atleast have the brains to use appropriate logos so they'd be semi passable, like I don't know TÜV or UL and so forth..
And, of course, they're nowhere to be seen on Qualcomm's certified accessories list. Not even any QC2.0..
P.S. I did apply for testing, they sent me an email, I replied. Let's see if they send something lol. I'm not a liar so I'm gonna be honest if I do get their stuff for review

Yer they look decent I already have some of their usb c cables, I've just ordered the qc 3 portable charger from them aswell so il review them all and see how get on. But yer they make no mention of favourable reviews they just want a review, which means they are confident in their products which hopefully means they are good

Nice, I have some on the way, they look good.

I actually asked this question at qualcomm but they wouldn't answer, maybe someone knows the answer here, hopefully it is not too confusing.
I was wondering about the QC 3.0 technology chargers. My question is, say I buy a wall charger or a car charger that supports QC 3.0); will it charge my type C phone (say an LG G5 or an HTC 10) as fast with the QC 3.0 technology using a type A to type C cable? I know if I charge a type C device using only type c it will get me faster charges, but if I do type A to type C (with QC 3.0) with the right charger will I still get the best results?
Thanks.

type A to type c wil reduce charging times even with 3.0. I went with these cables and for a car charger I got this one both should give the rapid charging.

Thanks for clarifying, I wasn't sure. I think the HTC 10 charger comes with 3.0 quick charge, but it is a type A to type C.

I actually just got my QC 3.0 Powerbank from Choetech and I love it. Charges everything fast just like the spec allows for, and has a great build quality. One small thing I like is that when fast charging, the first light to the left switches from blue to green to indicate that. I just appreciate the assurance that my device is gonna be juiced up quick. The only thing that's odd about it is that you need to press the power button for charging to begin. I'd prefer it to just start when a device is connected, but that's my personal preference.
Overall I still really like the thing, great to have a powerbank that charges just as fast as my wall charger, before I was stuck with one that didn't have and QC capability. I'll include some pics below.
If anyone has any questions about it, let me know. Should also be getting a 6 port QC 3 charger from them soon too, will post on here when I do.

I was looking at this on Amazon last night, but they don't seem to be on Qualcomm's official partner list, which makes me a bit nervous for my battery (which I'm not super impressed with anyway so far - one of the reasons I was looking at the power bank). Do either the phone or the charger get hot while charging? The HTC QC3 charger seems to prevent overheating.

They aren't, but speeds have been up to par with what I'd expect from QC3 so far so I haven't had problems with it. The charger gets warm after a bit, as does the phone (warmer than with stock charger) but also nowhere near as much as the M9 would when charging. Don't know if you've used that before, but when charging regularly it would get so hot that it had to stop, and that's even with screen off. It was crazy bad at charging, which is a thing I never thought I'd say about a 2015 flagship....so I'm glad the 10 is better in that regard, at least. I'd imagine almost any third party charger is gonna make the phone hotter than the OEM one will, but I didn't have a problem with the heat it generated, overall.

Updated [Comparison] HTC 10 QC 3.0 Charging test, QC 2.0, Type-C Fast Charging

Method:
First I used my phone until the battery was below 15% in order to get a better picture of what the charging would look like over almost a full battery cycle. I did not start at the same battery percentage for each test because I did not find any benefit to doing so. I original did this for uniformity, but it did not make a difference after trying it using the more accurate equipment.
I then cleared my history in the Battery Monitor Pro Widget (BMW Pro) recording app which was used to log the battery [mV], battery temperature [F], time, and battery percentage changes. Once this was done I plugged in my USB Power Monitor, turned airplane mode on, removed the case, and let the phone charge. I started logging the data via my power monitor once the phone showed it was charging. From this point onward I let the phone charge without interrupting it until it reached 100%, then I let it charge for another 10-60 minutes to see if it was still drawing power from each charger. Once all of this was done, I exported my data collected from BMW Pro, emailed it to myself, and pasted it along with the USB Power Monitor data into an Excel spreadsheet. All of the data was then delimited to separate the clusters of data due to the way they were recorded, and subsequently graphed. The USB Power Monitor recorded data points every 0.36 seconds, while the BMW Pro took recordings every 5 seconds because I was having issues with the “real-time” recording option in the app working correctly.
All of the data was then graphed into the nice figures you will see below; each color reflects the same variable across all of the graphs to make reading them easier. I included a legend at the top of each set of graphs which should also help make it easier to read the data.
Equipment:
These tests were conducted using a series of different chargers. The same brand was used for both Quick Charge 2.0/3.0 tests to minimize experimental error; This trend remained the same was also done for the wireless charging tests
Wall Chargers:
Quick Charge 2.0: Tronsmart 18W charger 5V/2A, 9V/2A, 12V/1.5A
Quick Charge 3.0: Tronsmart 18W charger 3.6-6.5V/3A, 6.5-9V/2A, 9-12V/1.5A
Cable(s):
Stock HTC USB A-C cable
USB inline Power Monitor:
XYZ Studio 0-24V, 0-3A USB Power Monitor
Tronsmart 5-12V USB multimeter (not used in this test, but was used in the older version)
Software/App(s):
Battery Monitor Widget Pro
Excel
Notepad++
Realterm (for the USB power monitor logging)

QC 3.0 Tronsmart Charger
QC 2.0 Tronsmart Charger

I thought qc 3.0 was just supposed to be more energy efficient and produce less heat than qc 2.0. I never heard it was supposed to be faster.

I like your Tests. But why do you measure all 5 Minutes?
The App BatteryLog Records state every time the % changes.
Sadly the Bluetooth Module on my usb Powermeter broke off. So I have to get this repaired first before I can do any charging Benchmarks

Actually recording it is more accurate than any app will be. Now that I have a baseline I could see if the app is accurate but the last time I checked out wasn't.

I can add an actual plot of it too if you would like. I am going to conduct a test using QC 2.0 to see how it consists to QC 3.0 maybe tonight if I get a chance. If there's s anything you would like to see let me but know.

I'm not sure is this is accounted for but I've noticed this is the first phone I've had that I can remember having the battery percentage seem accurate. My G3 would hit 100% but if I left it on the charger an hour past that, I got more out of my "100%". I would at times get 30 mins SoT on 100% but then 3 mins per afterwards. My HTC 10 actually seems to drain evenly throughout the 3000mAh which means while a G3 may read 100%, it's actually at 91%. Other phones could have inaccurate percentage reporting which make for a greater perceived charging speed.

Since you've done a lot of charging, are chargers with QC 3.0 supposed to read "Charging Rapidly"? My QC 3.0 car charger didn't say "Charging Rapidly" with USB C to C and I'm wondering if I need to send it back. It did charge mighty fast though.

Well what charger were you using? If the charger doesn't support QC 2.0/3.0 from the Type-C port and instead uses the Type-C standard (5V/3A) that the Nexus 5X/6P use, then it won't fast charge. I never look at what the phone says because its irrelevant so I use a multimeter instead. The only downside to that is that no C-C multimeter's exist yet. The phone can only support 1 charging standard at a time, so that means it either supports Quick Charge 1.0/2.0/3.0 or Type-C fast charging not both. That is why is will charge slower over a C-C cable unless the Type-C port on the charger supports Quick Charge from Qualcomm not the USB standard version.

The Aukey 3 port car charger and it says the USB-C port is QC 3.0. Guess I should assume it's actually doing what it's supposed to since it charges stupid fast.

On Topic: Those numbers for the HTC 10 QC 2.0 vs 3.0 are very interesting. Looks like QC 3.0 is definitely more efficient. And I assume changes in voltage are it monitoring temps and trying to keep them down. This is all new to me so I'm learning.

It should charge at QC 3.0 speeds from my understanding. I have a Tronsmart wall charger that supports QC 3.0 over type-c, so I can test it when I get a chance.
I am redoing both tests with the same brand of charger since I used the stock HTC charger for the 3.0 and a Choetech one for the 2.0 test. I will be using Tronsmart chargers for each of the new tests, and I will post them up with the old ones. The QC 3.0 does really keep the heat down that much, because if it did the current and voltage could be much closer to the 18W it seems to support on this phone. QC 2.0 seems more consistent and maintains its output longer before tapering off which can be a bad or good thing. I might download an app to verify my results and to see the temperature, but I don't know how well that will work and or if it will affect the charging times.

Charging speed on various ROMS

I know DASH charge is not supported on roms until later in July when the source is released but what are the charging speeds on various roms?
Do they get full charging speed at 5V?
On my oneplus 3 - Oxygen OS - I get 5V 1.5amps with the google nexus 5v/3a charger. In fact, it seems to limit charging speed to 1.5amps max for non dash chargers.
Can ROMs get 5v/3a?
Thanks,
Rico

Not until OP releases the source code. Hopefully by the end of July DASH charging will be implemented in custom ROMs.
The OP3 light ROM is basically custom stock and supports 5V/4A charging.

Not exactly what I mean. Can any of the custom Roms charge at higher than 1.5a at 5v? Most phones now can at least go to 2a if not 2.4a. Nexus 5x/6p can charge at 5v/3a.
Any Roms with charging rates above 5v/1.5a?
Any kernels?

i got that same observations too if some kernel is released which can take at-least 2A of current without the dash chargers it would be awesome as then we can charge fast from power banks too

I would love them to remove the 1.5a limit as it 'currently' stands... Crazy that they don't allow rapid charging that's possible with Nexus usb-c to usb-c spec adapters

Certainly you can do that. I was continuing to talk about how the Stock ROM from oneplus is handicapped by limiting charging that isn't Dash, to 1500mA max input current (as far as my observations and a quick Google have shown), just complaining about Stock basically... Java
I guess they want you to buy more Dash equipment instead of getting 3A rapid charge out of a usb-c to c spec charger

This is because the Limit of the cable. Most cables only support 1500mA. So to prevent it from smelting it will only Dash charge with a Dash Charger..

People tend to not understand that the limitation is there for safety reasons. You can't safely use all kinds of fast charging with all kinds of hardware.
DASH keeps the voltage at stock 5V and bumps up the current to 4A, which would destroy standard cables (too thin).
Other types of fast charging mostly keep the current lower, but bump up the voltage. OnePlus 3 *does not* support QC3 (technical limitation, not software) so you're stuck with 5 volts. And at 5V you can't safely go above 1.5A with any cable.
So, if you want fast charging, you have to use DASH or VOOC (VOOC accessories are confirmed to work as intended with OP3 and tend to be cheaper).

Sure, I understand that, but none of this is what I'm asking as far as I'm aware. Let me say it like this..
I'm sat here with three Nexus chargers.
They output 5V at 3A (to a 5X and 6P) as per USB-C to USB-C spec.
I also have a PC motherboard with a USB-C port. It also conforms and allows 3000mA through the cable. Because all USB-C to USB-C CABLE is supposed to allow up to 3000mA by the standard. DEVICES can request that to be 1.5A or 3.0A.
The USB-C to USB-C spec cable is 3000mA
I plug it into my OP3 and it only allows 1500mA
I'm pretty much just *****ing at Oneplus for not allowing something LESS than Dash charging on a certified specification for the USB-C port.
We are taking 5V 3A USB-C spec (can't by design be thin cables) versus 5V 4A DASH (custom USB-A cable) which means NO danger of melting cables.
So is the OP3 port just not compliant?
To follow up from wiki:
All USB-C to USB-C cables are considered full-featured USB Type-C cables and must be active, electronically marked cables that contain a chip with an ID function based on the configuration channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB Type-C devices may optionally support bus power currents of 1.5 A and 3.0 A (at 5 V) in addition to baseline bus power provision; power sources can either advertise increased USB current through the configuration channel, or they can support the full power delivery specification using both BMC-coded configuration line and legacy BFSK-coded VBUS line.

So basically Oneplus in my eyes must have made a call to not enable 3A on a USB-C/USB-C cable, seeing as the in-device hardware is able to stomach 4A. It's just a matter of allowing communication to the USB-C spec charger to say, send 3A, I can cope with it.
I'd love to hear what you guys think.
I have a USB-C/USB-C car charger with 2x USB-A ports, and so i'm really bummed out that the OP3 won't accept the perfectly reasonable and safe 5V 3A it can give. I use the two other USB-As for other devices, so I don't want the single port DASH car charger from OP. It's a waste of space and investment...

I see that I forgot to mention another important piece of information before - the statement that I quoted here is not entirely true.
Remebrer that OnePlus boasted about keeping the device cool even while fast charging? Well, that's because they moved some of the hardware from phone to charger itself. Meaning that the phone alone does not have all the necessary internals to handle different charging inputs. Which is probably the reason that it only gives you 2 options: DASH or standard 1.5A @ 5V.

Yes, but literally three amperes is less than four amperes. The voltage is the same. There is no different internals technically required to intake Less then the maximum amperage, that's just plain electronics.
The issue with heat they quote is due to Qualcomm Quick Charge using higher VOLTAGE which means a greater 'pressure' of current. Higher voltage needs better internals, but both of what I'm talking about are 5V and need no additional hardware to receive LESS amperage of 3A versus DASH's 4A.

every new roms support dash charge now

What is Superfast Charging actually?

So what is actually superfast charging? Is it just Samsung's term for USB-PD? Does our phone support USB-PD? I'm still relatively new to this charging protocol.. What's PDO and PPS?

Hello
This "Superfast Charging" is very similar to Qualcomm's Quick Charge technology but is somewhat more proprietary. Remember when Samsung launched 15W fast charging with the Galaxy S6? This is basically the same kind of thing, except instead of being only 15W, this is 25W. For comparison, a regular laptop charger from the last decade or so can support anywhere from 40W to 120W(Possibly more). Apple's newest MacBook Pro comes with a 96W charger. It supports USB PD (power delivery). However, USB PD has a very specific standard and is only supported over USB C cables, and has to be 60W or more. If you were to plug a USB PD cable into a device which only supports up to 25W, then the device will only draw up to 25W. The reason laptops and some devices can charge faster than others is because of the chemistry and thermal management they use. Remember, a hot Lithium Ion or Polymer battery is a very bad thing, and the faster a battery charges, the more heat it produces because of internal resistance. Though you may hear about something like Wh (watt-hours), this is very different to W (watts), since Wh is a unit to measure how much energy a cell can store, while W are generally used to measure HOW FAST a cell can charge. PPS is an acronym for Programmable Power Supply, this basically means that the power supply (or charger) is able to change the amount of current it supplies, so that it doesn't fry the circuitry of the device if it cant handle it. PDO is an acronym for Power Data Object. GSMArena has a good article about this.here
I hope I answered your question, oh and sorry I got carried away with the length , I find these kinds of thing quite interesting!

Thank you for the detailed explanation, now for my real question : can you plug a USB hub with multiple USB-A ports and a USB-C port and charge to this device through said port using any charger?

No, that's not true. USB-PD is flexible in it's power delivery and was designed to be one standard for all usb devices.,

I tried and apparently it is possible. But the charging would be standard charging.

This will mostly depend on the device itself, as well as the hub you may be using. This is because we are not certain what the manufacturer intended the product for. If you have a hub like the one you described, give it a go. It should work but if it doesn't, the worst that can happen is it doesn't do anything. No biggie!
Oh and also, just make sure that the charger you'll use is powerful enough, just to make sure that your host device will actually charge at a reasonable speed.
