I've had my 7 Pro 8/256 for a week now and was really hoping to see USB-PD 5V3A charging. In fact, I ordered a USB-PD USB-C power bank specifically for this.
I've also tried my Aukey PA-Y10 46W Wall Charger as well. USB-PD (PDO) 5V 3A | 9V 3A | 12V 3A | 15V 3A | 20V 2.3A.
USB-C to C Cables, U Green 3ft and Aukey 3ft.
When I connect the power, it doesn't indicate "charging rapidly" as it does on Pixel 2/3. Tested using Ampere. 1.7-1.9A even when the battery is only at 20-40% Far cry from 3A max.
When connected to the Dash Charger from my OP5 with OP5 cable, I get the standard 5V4A (3.3A in Ampere) of Dash with a Charging Rapidly logo and a blue lightning bolt.
Were we lied to? The article says it is supported but there is nothing indicated during my real world testing to show it actually is any faster than using a 5V2A charger. I livechatted with OP Support yesterday and they did confirm that OP7 Pro supports 5V3A USB-PD spec but the rep didn't understand what I was asking when there was no notification for rapid charging.
https://www.xda-developers.com/oneplus-7-pro-usb-pd-hdmi-variable-refresh-rate/
yeah on my PD charger it takes 1 hour 50 to charge from 20 to 100
If you want to see the actual rate of charging, I recommend using an app called 3C Battery Monitor. I use it to keep track of my phone's rate of battery drain when using certain apps or how fast something is actually charging. In order to save battery, I only have it logging the battery usage every 10 minutes but you can set the rate to be faster.
I'm my first picture below, I was purposely draining the battery down to 1% to test out the speed of the warp charger, but it was only sampling every 10 minutes.
My second picture is set to every minute.
Give it a try to test out the PD charging as you will have actual mA/hour figures to compare.
Thanks. Confirmed today that it does do 5V3A but doesn't show as "charging rapidly" using 3C Battery Monitor.
It is about 2.9-3.0A from about 25% until 70%. From 0-25% is about 1.5-1.9A and from 70% onwards it slowly decreased until it reaches 100%.
In total from 17% to 100% took 1h 47 mins. Not exactly fast but acceptable.
With the Warp Charger, it's 0 to 100% in about 1 hour flat. With a Dash Charger, it would be about 1 hour 30.
iPhone XS Max charges 0-100% in 2 hours 20 minutes with a 2.4A adapter

Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol

i just used the stock fast charger on my zerolemmon with fast charge on and i never let it go the full 1 hours. Ive had insane battery life with it so i dont think it matters

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Wow. Good info. Thx. Now a ton with a hack to draw more amps lol. Hmmmm lolol
Hey guys, just to let you all know on my findings. I have Nexus 5X charger (rated 5v 3A) and decided to try on my A1.
It goes from 63% (I think, I forgot to write down the actual %) to 100% in 45 minutes. Considering usually after 80% it will charge slowly, I think this is pretty quick time.
I'll test it again some more when the battery level is much lower and report back.
I'm on latest Oreo stable
OPR1.170623.026.7.12.29
are you measuring the charging amperage after 80%?
37% in 45 minutes isn't all that fast, imo.
I'll measure charge time tomorrow, stating start percentage and I'll look for what happens after 80%, to see how much it drops in charging amperage.

I didn't measure it's amperage, just check the time till it fully charged.
If do the math from this charge means from 0% can be fully charge in 82 minutes. That should be faster than stock charger. One caveat though, if it's really 63% and not 73% when I start charging it.
Now my phone already 2 hours SOT and almost an hour hotspot, but still left 74%. Not easy to deplete it's battery.
One more thing I forgot to mention in first post, I'm on latest Oreo stable.

From what I read, Quick Charge would use dynamic voltage (5v-20v) instead of utilizing higher amps to attain higher wattage charging.
Use ampere app to measure current.
For better results try charging it while its off from 0 to 100.
And try while its on.

Ok I'll try it when I charge later. Now the battery still left 50%. I'll drain it another 10% at least before charging.
its still same as before.
only below 2A
Sent from my Mi A1 using Tapatalk
Alright so my battery was at 42% when I plug in the charger. Using ampere it stated Max USB Curr is 2000mA. And the reading max is 1930mA while average is about 1800mA.
After 20 minutes it have gone up to 65%. Reached 90% after 43 minutes. At exactly one hour it reached 97%, which I checked ampere reading is 440mA. 100% reached at 64 minutes.
During charging I received a call which lasted about 3 minutes, which I use loud speaker for the call, so here might have added few minutes to it's charging time.
So I guess the speed is around the same when Oreo beta is?
Start time: 0805h
Battery: 38%
Check in time: 0905h
Battery: 87%
Did see that the amperage has lowered to around 1A after the battery reached past 80%. It definitely decreases after 90%, I'll check this the next time I charge.
I can run the test again with a different usb measuring tool. This first one seems to indicate a lower voltage than my other tool by about 0.2v (and amperage by about 0.2-0.3A. Although it should just be a passthrough for the power, it may be inhibiting the power sent to the phone.
The measured amount of power sent was ~1600mAh to get the phone to 90%. That seems about right for 52%, give or take.
i try with Honor 8 Pro QC charger (9v 2a) and it goes from 0 to 78% in 60 minutes, phone was off. I don't know the total time to 100%, sry
Stayed around 1400 mA for me above 80%

1600mAh is the amount of power that was sent to the phone, as measured by my USB measuring tool. If you're talking about amperage during charging, I get around 1.9A on average. It fluctuates between 1.85 and 1.95A, and the voltage fluctuates between 4.95 and 5.20.
This is using a Tutuo charger which is capable of QC 3.0, and also 5v/2.4A.
I've tested using the regular 2.4A port and the QC port.
Basically, this phone does not request more than 2A at most, so even a 3A charger isn't going to make a difference.
I am using stock charger only. Don't have fast charger won't buy it unless phone supports it

How much mA you get from ampere when using the stock charger and batter is less than 80%?

Edit: since you are trying so hard.
From what i have read few years back when i had xperia zl
Incase of zl max current was capped at 1.5 A
QC 1 is 5V 2A our charger 10W
I bought Samsung 5v 2a charger for my zl. I still have it. Works fine. (Just adding history to context :laugh
QC 2 was designed to give 18W(average)
5v 2a QC1 compatibility
9v 2a QC2 18W output
12v 1.67a (from Wikipedia)
QC3 went with higher amps and dynamic voltage
Don't know anything about QC4
So give 9v 2a a try while measuring current take screenshots multiple times to track voltage since i don't know any other way to measure voltage except what ampere already shows.
PS: i know commands to read from proc and all but since i haven't rooted my device i won't ask you to go through that way.
I used lenovo charger which support 5v-2A, 7v-2A, 9v-2A and 12v-2A
Started charging 12:54 AM, battery at 4%, airplane mode activated
and these are the results

I tried with 9v 2A charger, still capped at 5v and almost 2000mA.
One interesting finding is using the 9v and Dash charger plus their cable give consistently almost 2000mA, whereas if using Mi charger and cable; or Dash charger and Mi cable; or Mi charger and Dash cable; all give around 1700 to 1800mA averagely. I think Mi charger and cable is of lower quality and unable to max out 2A.
The conclusion that I found is if want a slightly faster charging then use other better quality charger and cable.

That's as fast as when Oreo beta is. Like I suspected Mi original charger and cable unable to max out the ampere.
Thanks for all the hardwork???
This thread should be locked now and made into sticky.
Cause this is nothing short of a research on fast charging in Mi A1.
Hi There,
I just read that Mi has not opted for Quick Charge by paying royalty to Qualcomm. So they have disabled QC functions from software side, though chip is definitely capable.
By Mistake, they let Beta have QC functionality. But now that has been fixed.
We now have to find way to enable it ... If possible.
i set my battery limit at 85%
current s22 ultra at 12% , using 25w it shows 41 minutes until full (85%), shows Super Fast Charging
at 12% using 45w charging, it shows 34 minutes until full (85%), showing Super Fast Charging 2.0
so 45w is like 7 minutes faster. spending every less minute count, 7 minutes less.
Do you happen to have the model number for your Samsung 45W Charger that you're using? Also, did it come with a 5A USB C to USB C cable?

This sounds about right. The way the tech inside the s22 ultra works is it lets you 45 watt charge the battery from 0 to 60%. After 60% it slows the charging down and it's not as fast to fill up. That's why you only get 7 to 10 minutes of faster charging with the 45 watt versus the 25 watt.
If you wanted to see much bigger charging speed numbers then Samsung would have to go to something much bigger like say a 60 watts. 25 watts to 45 watts is just not that much of a big difference. But 25 watts to 60 watts or 25 watts to 100 Watts definitely is.
someone should sue Samsung for false advertisement !
my phone is at 34%, i using those USB-C cable with LED watt display, it only showing 31W on my home aftermarket 65w charger, it showing the same 31W on my aftermarket car charger too. unless samsung OEM charger able to charge at full 45w, then it's false advertisement !
someone really need to sue them !
Sue for false advertisement? Haha right. Because it doesn't work with aftermarket chargers, which no company is ever going to say work with their phones anyhow. Until we get a proper test with power meters, a new Samsung charger, and 20V/3A cables we just don't know. We don't know what the YouTubers or anyone else is actually using at this point. The charge voltage to reach 45 Watts seems to have gone up to 20 volts, which might put some cables out of that sort of territory.
I tried using two approved chargers. The Anker Nano II and official samsung 25W charger. Getting capped at 15W. Am I doing something wrong?

Same here, I don't think it'll ever go to 25W. One of those Samsung unfulfilled wishes? Am using the original 25W charger and DevCheck Pro readout shows oscillating wattage between 18.8-17.3(battery level ~35%) Maybe they could fix it w/OTA software?

I use this charger and the screen-on charging value goes up to 4 Amps (as reported by Accubattery) so I guess this is the perfect charger for 25W charging. Also in the specifications, the rating is mentioned; some are very near to 25W.
If you want to figure out the wattage use the simple formula W=V*I where W=wattage in watts, V=voltage in volts and I=current in amps.

Been using the very same EP-TA800 adapter, "25W" as Samsung misinterprets it because it only goes to 18W max or so: (started at 26%, second pic 45min later)
You are right, I can confirm also that the 25 watt charging is just gimmick.
When your phone are low battery (under 30%) you only get 25 watt of power pulled from your charger for a minute or so.
Then the continue charging speed are about 18 watt.
With AccuBattery pro app, after several various charging time, I get average of charging speed = 90% per hour
Usually I charge my battery from 20% to 85% in 44 minutes. With phone screen off about 30mins.
You can also check what charging levels you are supporting by going to Settings -> Battery and device care -> Battery -> More battery settings
Just a heads up for anyone not coming from the Z Flip 3, though, that Samsung reset the evolution of USB-C on the series. The Z Flip 3 launched with 3.1 and 15W, while most other phones were 3.2 and 45W charging.
If you follow Samsung's upgrades, you may already know that the difference in capacity between the Z Flip 3 and Z Flip 4 is 400mAh. Ironically, the difference between the S9 (15W) and S10 5G (25W) when 25W released was also 400mAh.
Samsung's linear progress aside, the charging difference is only noticeable in the first hour. You can read more about it at https://www.sammobile.com/2019/05/02/how-fast-is-samsung-25w-super-fast-charging where they compared the standards in depth.
Is there a difference in charging speed between an Anker Nano 3 and the official Pixel 30W charger? I bought the Nano but accubattery tells me it only charges at 17 watts while the P7P should go up to 23 watts. Should I return it and get an official Pixel charger? Or is it normal that it doesn't reach 23 watts? Adapative charging was off while charging.
Since Anker is a well known brand, I would test it another charger. It very well could just the device only pulling 17 watts at that moment. I have multiple Anker chargers, cables and hubs at work and home. I have never had a charger fail or come up short on the rapid charging.
I have Anker cables and I noticed they charge much slower than the cables that came with and are designated for these devices. Still faster than my cordless charger.
Thanks for the replies. I'm using the official Pixel cable. I think I will order a Pixel charger and see if there's a difference.
I am using an Anker Nano Pro (20w) with Anker cables and my P7P charges in just under 2 hours which is only a few minutes slower than the official 30W brick.
This is a good read https://www.androidauthority.com/google-pixel-7-charging-30w-3226058/
Thanks, that's interesting. I will let my battery deplete further and see if the wattage is higher when charging from a lower percentage like that article says.
I am sure i have read in the past the Pixel 6 Pro over the whole charge averages only 13W, if your reading is for the average and not peak wattage then maybe 17W is right
Keep in mind that maximum charge wattage will drop off if the phone is doing things at the same time. Just turning my screen on and looking at the AccuBattery charging screen takes between 1-2W and there are spikes beyond that as apps do things.
It's not worth buying expensive chargers to get the highest wattage possible as it's a negligible benefit since the average is going to be way lower than the peak anyway. Both my OnePlus 9 charger and my Anker charger seem to peak around 19.9 watts with the screen on and they both support USB PD PPS.
