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

I can use Dash Charge here with CM13, no problems at all.
Maybe you are using an old ROM?

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
I ask this since it seems more feasible than enabling something like Quick Charge 3/2.X since this method is open and not proprietary.
It also seems feasible since the OnePlus 3 can clearly handle up to 4A of current at 5V (dash charge) so in terms of hardware it should be able to handle 3A at 5V similarly to the Nexus 5X/6P via the standard USB-C spec.
It doesn't even seem to be able to handle 2.4A via a USB-A to USB-C cable, or even via a USB-C charger using a USB-C cable.
Is there some hardware or software limitation I'm perhaps missing? If it's a USB-C device it should be able to charge via the USB-C standard
To my knowledge one plus promised dash source by the end of July. Also to my knowledge is something must be enabled and PCB hardware must enable fast charging. Galaxy s7 doesn't have qc3.0 despite having the correct hardware.

i do understand something needs to be enabled for QC2/3.X but why for USB-C?
Short answer ... no one knows and they're talking out of their ass ...
Long answer - Even if its a hardware/software enabled type feature - most do not know how to program it well enough to incorporate it. So everyone has to rely on source code with it already programmed to include it with any rom. Some guys can program it but dont have the resources and/or phone to do so. The average programmer reading your comments doesnt know specifics which is why you get a lot of "to my knowledge" "as far as I know" "in theory" type statements

Quickcharge is closed and proprietary, it's just the licensing is cheap. It only work on phone that have recent qualcomm SoC. Yes our OP3 have a SD820 but the manufacturer also have to implement it in the phone, with software but also hardware.
It's a shame that Oneplus didn't use Quickcharge because with the price of one Dash Charger or VOOC charger you can buy a 6 port quickcharge 3.0 charger... And quickcharge can use standard cable (if you use another usb C cable than the one provided, the red and blue one, dash charge don't work even with the dash charger)
So I'll tell you one reason why the Oneplus 3 won't support quickcharge even with some hack : charging a lithium battery at a high voltage make it go BOOM!
Quickcharge use 9, 12 or even 20V to make charge faster (and it's an advantage with low quality usb cable). So the phone have to be able to convert 9 or 12V down to 4.2V and it's a hardware matter.
Now for the 5V/3A of the USB-C spec, it's Oneplus that limit it (and it's safer that way). I tested many charger with a voltmeter. I used some charger from 1.8A to 2.4A and it only draw 1.5A. I used a genuine apple charger at 1A (the A1400) and it only draw 0.5A, the same when it's hooked on a computer. With the dash charger and the dash cable, it go up to 3.5A. It's not 4A but it charge pretty fast. With the same charger but with a normal USB-C cable (2.0 and 3.1 i tried) it draw 1.5A.
So the dash cable use some extra pin to make the phone identifying the dash charger and the dash cable, when one is missing, it charges at 1.5A or even 0.5A.
Why Oneplus don't use the full 3A of the USB-C spec? Dash charge/VOOC I guess.

If it's "unsafe" then why would Google use in the Nexus line? If anything, all of the quick charge out of spec systems (like dash charge or quick charge) are "unsafe"

you can have BOTH. why REMOVE USB-C 15W charging?
charging slower is safer than charging at high voltage or intensity, I didn't imply anything else.
If the charger provided can do 5V 3A like the one provided with the Nexus 6P can actually charge at 3A a Oneplus 3, how can you sell a dash charger with a dash cable that do 3.5A (and the VOOC charger that is even more expensive and need a micro usb to USB-C adapter)

Easily? Dash charge is far more quick not to mention heat efficient
Also, slower charging is not safer by default -it's less hot charging that is safer more so,
Dash charge is heat efficient? Yes it will be warmer on a cold day. Like any battery charging slower is better for the battery life.
I don't understand your last sentence, sorry
If you are talking about the efficiency between the power on input and output from the charger, I think that the power is not high enough to really make a difference with a standard charger.
I am still a big fan of Qualcomm quick charge because I could use a 3 meter (10ft maybe) usb cable not even made of thick gauge.

I think what he is getting at is during quick charge the higher voltage results in more heat in the phone, with dash charge the heat is contained in the charger. Thus phone stays cool during charge which is safer for the phone.

Hey!
I noticed recently that my G5 charges quite slow. So I tested all of my powerbanks, cables, and wall chargers, in various combinations. I had 4 different powerbanks, 3 wall chargers, and 4 cables.
I used a USB ammeter to measure the power draw going through the USB cable.
On the motorola charger and cable that came with the phone, it charges at 1.8a. I then charged my phone from each powerbank and wall charger, using each cable in turn. The average charge speed for my phone was about 0.5a. Out of 28 combinations, only 2 yielded a draw over 1a.
I have created a spreadsheet detailing the charge speeds of each combination, but unfortunately cannot post it yet (10 post permissions).
I then charged my USB powerbanks from the same wall chargers, using the same cables. One powerbank charged at over 1a with every combination, and reached over 2a on numerous combinations. This proves that the cables and wall chargers are not at fault, it is a phone issue.
Why? Has motorola put something in their chargers that 'talks' to the phone, and allows for faster charge speeds? 0.5a is awful!
Secondly, does anyone know of cables that I can buy, which will support fast charging for the motorola? I have looked at genuine motorola cables, but there is no way to tell one from the other.
Thanks!
Paul
P.s. charge speeds were the same, whether the phone was switched on or off.
Welcome @agour
I've come up to a similar conclusion with a lot less data (thus I didn't share them).
I caught power consumption at the wall outlet when charging my device with two chargers: Motorola stock charger and a Samsung Adaptive Fast Charger.
The Samsung has the following specs: 5V 2A or 9V 1.67A with fastcharging capable device.
Using Samsung Adaptive fast charger and Samsung 1.5m cable : 6W, so the device charges at something like 5V 1.2A...
Using Samsung Adaptive fast charger and the cable provided with my XT1676 : 11.3W (which is coherent with the max 9V 1.6A, and would mean the charger provides 2.2A if at 5V which more than the specs.)
Using stock charger and stock supplied cable : 11.3W ==> fast charge for similar reasons as above
Using stock charger and Samsung 1.5m cable : around 6W ==> low power charge
I'd need a USB multimeter to confirm those data. (mostly due to the variable voltage that can provide fast charge adatpers)

Interesting! It's suprising how much difference the combinations can make.
I don't think I have experienced this on a phone before, however I have never felt the need to test it...
I tested the original cable that came with the phone, and an off the shelf 'genuine motorola cable'. The stock cable is still the fastest, however the secondary cable still worked very well.
Interestingly, one of my powerbanks will charge at 2.2a from pretty much EVERY powersource and cable combination. This is with 7 cables tested, and 3 USB wall adapters.
Shame that motorola doesn't allow their phones to draw maximum power from hardware that can provide it..

If I have some time, I may test internal impedance of the cables, it is possible that the device somehow probes the cable (or the cable + charger) and then decides if it can or not draw that much power without overheating/melting the cable; and then it will negotiate the quickCharge with the charger.
there has been a discussion about quick charge on this thread a while ago (before I got this devices : https://forum.xda-developers.com/g5/help/quick-charge-3-0-support-t3632457)
Lenovo adds the following that I have not tested:

It is quite obvious that especially cheap cables will charge phones much slower as the resistance is too high, even if the phone does not perform any checks. Those cables are basically too thin. Resistance limits the current (amps) that can flow. Newer phones most likely just look at the charge current during the first x seconds (or less) and then decide wether to enable fast charging or not to keep the cable from heating up. A wire with high resistance is basically a heater. So it's a necessary safety feature (from the companies POV).
Regarding the power bank, it may be possible that this particular design provides a voltage slightly higher than the nominal 5 volts (still fine for most devices), which helps overcome the resistance. That is also the reason why the Samsung fast charger provides 9V: You don't need a cable as thick as with 5V.
Keep in mind that the USB specifications only recently got updated for such high charging currents, so it is advisable to use only the cable that comes with the phone as USB cables in general don't need to provide such high currents by spec!

That sounds correct, although my Samsung wall adapter is fast charge capable, and was provided with a cable (and not a cheap one), that basically can't be use for fast charging with the G5, that looks silly...
Lots of questions here...
G7 comes with QC 3.0 although the chipset can support QC 4.0 as per Qualcomm. I see on other forums that users can tell when their phone is quick-charging or slow-charging.
1) Does the G7 let you know what speed it is charging at? I'd like to know so I can swap out cables, chargers, Qi pad, to get the fastest charging rate.
2) Is there a difference between Samsung's Fast Charging, and Qualcomm's QC 3.0?
3) If a charger says that it is compatible with Samsung S9's or S9+'s fast charging, will it fast charge the G7?
4) is there a QC Qi pad that is compatible with our QC 3.0 phone? If so, can I assume that I would still need to power it with a QC 3.0 wall wart?
5) Will a USB-PD or USB-IF charger quick charge our phones?
6) What is the minimum QC cable type (USB 2.0, 3.0, or 3.1) needed to get the maximum QC 3.0 charge? Does it have to be a 3.1 cable?
7) I've seen that when I put the G7 on my 1st gen Qi pad (5W micro-USB) that the phone screen lights up, and a circle briefly appears with the charged percentage in the center (while phone is on stand-by). If the phone is unlocked and the display is on, a white window telling me it is wirelessly charging shows up and tells me how long until the phone will be fully charged (again, when placed on a Qi pad). It's currently telling me 19 minutes to full charge from 93%. Is there a way to get this remaining-time info while cable-charging through the USB-C port?
Thanks!

The charge rate of the phone irrespective of the chargers we use, it is controlled by the stock kernel. When screen is on, it lowers down the amperage (See Ampere App) to keep off the heat, vice versa etc. We need a custom kernel to have the charging amperes to be changed manually which is really cool. If we have a really cool custom kernel, the CPU governors should preset customisable governors (for smooth performance) and for the charge values, just look for a 3A charger, with the Kernel Adiutor change the values. Meaning the benefits of rooting gives us the complete freedom of our Android! If a 4A charger is detected by the kernel manager app, the charge values should show as "upto 4A even with the screen on! Then no need to be jealous of Dash Charging of One Plus!
I think this article will help you out... Breaks it all down... Samsung charger are not the greatest for fast charging but works better than a basic one... Ultimately I would say USB c to USB c with USB PD is your fastest with QC 3.0/4.0 being a close second..
https://www.digitaltrends.com/mobile/how-does-fast-charging-work/
I don't see that wireless fast charging is b supported by the g7 ... That's a Samsung gimmick ... But the Qi standard chargers charge at the same rate as a basic charger... The lock screen always tells you how long until full no matter what charger you are using and it will say fast charging, wireless or just charging... My observations have been around 1.5 hour for 60 percent to full so about 5 hours if dead, great before going to sleep and I missed it in my least few phones

Thanks! I noticed you do not have a G7 listed as a current phone in your signature. Is your answer above based upon your experience with Samsung phones and their charging system, or specifically with the G7 (or other QC 3.0 phones)?
I hadn't notice the charging speed on the lock screen, as I have the phone set to basically bypass it all the time (fingerprint, facial recognition, & geo-fence)...so I didn't even know it was listed there on the bottom. Thanks again...now I know it's there
Strange thing is I went through a bunch of permutations with cables (various generations), and charge blocks and Qi pads this morning, and with the phone starting at 93% charged, it made no difference in remaining charge time no matter what combination of the items I hooked up. I saw the standard "charging" memo with some combos, and the "fast charging" one too, with others. Can I assume that even though the phone might say it's fast charging, it ramps the speed/power level up and down as necessary due to the current state of charge, or heat or some other factors? Would it also possibly switch into fast-charging with more power if the phone was starting at a lower state of charge, or possibly cooler?Yes, I'll have to read the link above as it's probably covered there
"Fast Wireless Charging" is supported and working.
I have a RavPower 15w and 3 umdigi 15w qi wireless pads that all say wirelessly fast charging when connected. Needs an 18w QC2-3 charger for the input voltage ranges needed to work.
It is noticeably faster than a 10w qi pad and only slightly slower than QC 3.0 USB average charge.

Of the 2 Qi pads you mention, any preferences towards one or the other (or a different one altogether)? I have an Anker QC 3.0 charger I can connect up to it.
BTW.. I cannot locate a 15W Ravpower pad. What model is it? And is the Umdigi a model Q1?

Thanks! I noticed you do not have a G7 listed as a current phone in your signature. Is your answer above based upon your experience with Samsung phones and their charging system, or specifically with the G7 (or other QC 3.0 phones)?
I hadn't notice the charging speed on the lock screen, as I have the phone set to basically bypass it all the time (fingerprint, facial recognition, & geo-fence)...so I didn't even know it was listed there on the bottom. Thanks again...now I know it's there
Strange thing is I went through a bunch of permutations with cables (various generations), and charge blocks and Qi pads this morning, and with the phone starting at 93% charged, it made no difference in remaining charge time no matter what combination of the items I hooked up. I saw the standard "charging" memo with some combos, and the "fast charging" one too, with others. Can I assume that even though the phone might say it's fast charging, it ramps the speed/power level up and down as necessary due to the current state of charge, or heat or some other factors? Would it also possibly switch into fast-charging with more power if the phone was starting at a lower state of charge, or possibly cooler?Yes, I'll have to read the link above as it's probably covered there

My pixel screen went bad and the charging port went bad also... Just got the g7 so I haven't changed my signature or updated my devices...
Samsung Fast charge is basically qc2 ... And standard USB A to C do not support the higher current that USB C to C does... I notice fastest charging with my pixel USB PD charger...
And yes you won't notice as much fast charging from the top 20 percent of the battery to prevent over charging...
for me, from 25% of charge, the fast charge advertisement says 1 hour and 20 minutes (charge fast???????).... if i use a normal charger (not fast), the time goes to 1 hour and 31 minutes. this phone has a charge fast but very low fast

Of the 2 Qi pads you mention, any preferences towards one or the other (or a different one altogether)? I have an Anker QC 3.0 charger I can connect up to it.

I know it's hard from a specs perspective as most are only 75% efficient so the 10w might only be 7.5w and 15w is actually 10w, which is why LG customer services expressly states you must use a 15w QI charger for fast wireless charging. Another problem is the specs aren't always accurate and updated devices might still have old specs listed. I tried a bunch before I found a couple I liked. The mophie streampad+ also does fast wireless charging but is listed as 10w.
The RavPower is a standup charger I use in the office, the other UmDigi chargers I have scattered around the house and in the bedroom.
RavPower: https://www.amazon.com/gp/product/B079C1QLCR
UmDigi: https://www.amazon.com/gp/product/B07DJ56LT5
Did a little charge test from 50 percent
Wireless charger =1h 40m
Stock iPhone charger =1h 14m
Both pixel USB C to C and stock fast charger =1h 2m
I'm in the market for a qi charger that can fast charge my Thinq g7. I see reports of needing 15W but not seeing many out there that have that spec.
I have seen a RavPower one posted here that is said to do it but the price is quite high for that model. Does anyone else have experience with fast charging the thinq g7 with a Qi charger?
I have Samsung Fast wireless charger. This present with S7. Fast charging battery of S7 Edge, S9+. But G7 didn't support fast wireless charging. And charging is slow. So you can buy what you want but charging with this phone will be slow.
I read this topic and wondering how G7 is going to wireless fast charge?
Sent from my LM-G710
Just thought I'd add to this - the charger that comes with the LG G7 ThinQ (Verizon) is labeled with outputs 9V/1.8A and 5V/1.8A. My old HTC 10 charger is labeled 12V/1.25A, 9V/1.7A, 5V/2.5A. I haven't tried it on the HTC 10's charger on a measuring device to see actual power delivery, but at least on the face of it, if it supports those higher voltages and/or amps, you should be able to get faster charging than with the charger out of the box.
On the other hand, faster charging may in part be why the HTC 10's battery lifetime is dismal, and not once have I thought "boy I wish my G7 would charge faster".
Anyone tried qc4.0 ?
According to some sites ThinQ is capable of 27W (9x3) charging. I therefore purchased a Xiaomi 65W charger which outputs 9x3 but the phone charges only with 15W (5x3) so wasted money.
Yes. I bought 3 different chargers and also a watt meter. When charging with screen on max amps is 1A and 6-8wattage. When screen is off it goes up to max 16watt. And it doesnt matter which charger i use.
80min for a full chsrge isnt that good. But think that lg g7 released in 2018?
Vivos IC00 something charges full in 20min. 4000mAh.
Im sick of "..reduced charging speed cause it can in a long term reduce battery......" who gives..? Then if you notice a different is gonna take 3 years and if still got same phone. Switch battery.
Look at Tesla batteries whos battery lost like 10 percent after 30000 km. I mean..come on
Im on 72% now and it says 45min to full.
A specialised site reported it would charge at 27W (9V x 3A) but this is simply not true. The best it can charge is 15W (5V x 3A). Thats it.
Guys, I bought this Wireless Charger Pad Slim EP-P1100T, to use on my Note 10 Plus, the information says it has a fast charge, but when I put my device on it, fast charge information does not appear even though it is enabled on the cell phone, is it really so? Android 10 does not show the message?
I think you should use Quick charge 3.0 charging head not the samsung 25w head with it , anyway even if you use the suitable charger with it Note 10 plus automatically shut off fast wireless charging when using slim pad for more that 20% of fast charging because of heat issues since slim charging pads don't have cooling fans and they heat up very quickly
I have one of these also, the only fast charger that enables fast charge with that wireless charger is my old Note 9 charger, it provides the 18w QC2.0 the wireless charger needs.

I'm using the charger that came with Note 10 + ...
Is that why the phone doesn't charge fast charge with the pad?

Yes, this charger was designed for the previous generation of phones (S9, Note9 ect) which included a compatible charger. Samsung confirms this here: https://www.samsung.com/us/mobile/m...nes/wireless-charger-pad-slim-ep-p1100bbegww/
Samsung doesn't use Quick Charge technology since it's a Qualcomm only feature and Samsung uses its own chipset which isn't Snapdragon.
Instead, it uses Power Delivery which is a standard and better in all aspects.

That's not entirely true, Samsung definitely do sell phones with the Qualcomm Snapdragon SOC and the 15W charging on most of their previous phones (S6, S7, S8 and S9 generations) was QC2.0 or QC2.0 compatible. This is why I am able to fast charge my Exynos Note 9 at full 15W with a QC3.0 charger.
USB Power Delivery is good but it's just another charging protocol, later versions of Qualcomm Quick Charge are also USB-PD compatible.

That's right it is, but there's more.
It's not just an other charging protocol, it's an USB standard, that's means all USB ports will have it by default.
Quick charge is proprietary licensed and will be dead soon because there's no use of paying licence for nothing.
And it's not the same at all. Power Delivery is made for dynamically adjusting current intensity and tension depending of the device you plug in and battery level, for them to take only what it needs.
Quick charge isn't, that's why you need dedicated QC ports on chargers.
It's easy for QC to be "compliant" if it shares one similar spec, but it's useless since all next USB ports will use USB-PD.
And that how it worked before, with fast charging, you only had to take in consideration that the output specs and the chargers is equal or higher to the input specs of the battery to get fast charge, but it's risky for the battery.
It may appear silly, but for efficiency and durability, lithium ion battery should not be charged at the same current and intensity at all levels and that's at least one reason why it's important.

I disagree but there doesn't seem to be any point in telling you that you're wrong.
