Hello.
Can someone explain me how on earth does fart charging works on this device?
I've tried the included cable and charger, third party chargers and i don't see any fast charging going on?!? or any indication on screen that it's happening.
I've read somewhere that you need a special cable to use with the included charger (?!?!) is this true? where do you get this cable?
Phone is amazing but the charging part is really is really weird if you ask me.
Thanks.

do you get any message saying fast charging?
it doesnt show any fast charging message, so i wouldnt rely on such a message to make sure its working. just use the included cable and charger and ull be fine it takes about 2.5 hours to charge from 0-100% via fastcharge

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol
Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00
trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.
I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.
Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.
i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...
Sent from my Huawei Mate 8 NXT-AL10 using Tapatalk
Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.

I have imported my Huawei and I absolutely love the phone. Since it is an import it came with a UK Type fast charger. I simply used a wall adapter and powered it over the US current. Well, that fast charger isn't working what so ever - after 2 hours I only go to about 35 percent from 0. I have used my Note 7 charger to charge it, and there the charging times are much faster. Any ideas on what, if anything, I am doing wrong and maybe where I can buy a working Huawei charger. I can't return the charger since I bought the phone over Amazon and it strictly came with no warranty. It is not the end of the world if I can't use the included charger I just want to see how fast this phone truly charges.
Either this post is a joke or someone sold you a non supercharge Huawei charger. Also are you using both the charger and charging cable that came with the phone in the box. It's white with purple in the USB A area
Here from 10 to 80% in 45 minutes
Same here. I find the first 80% to be lightning quick and then it slows to a "normal" charging speed for the last 20%.
Must be something wrong with your charger or cable.
Sent from my MHA-L29 using Tapatalk
Using the european adapter, not the UK one, but charging is lightning fast for me as well.
hi
the orginal adapter and cable
i charge from 0% to 90% in about 55 minutes, the last 10 % are slower maybe 30 minutes to full
greetz benji
Mine took almost 2 hours from 48% to 100%. I'm using Original Huawei charger.......
Install ampere and see what the milliamp charge rate shows as. When the battery is almost dead it should charge at just under 5 amps and will slowly decrease as the battery level increases.
Mine typically goes from 0 to 65% in half an hour, then 90% around half an hour on top of this. The final 10% takes almost another hour.

Well there is obviously something wrong with your charger, cable or phone. I would guess the first two.
Mine turbocharges in a few minutes. I've been using fir about a year now.
Could be that an "European" charger intended for 220 volts does not provide rapid charge when plugged into a 110 volts wall plug. I have for example an electric toothbrush I bought here in Europe and it refuses to charge on a 110 volt system when using an adapter. Maybe see if you can buy an OEM charger intended for the US?
There are 2 different chargers that are official, there's the supercharge one that comes bundled with the phone which I guess everyone is using and is getting great charging speeds... (Gotta use both the charger and the cable)
And then there's the fast charger which is pretty slow compared to the bundled charger.
The next time you wanna travel abroad make sure you buy a supercharger for that regions type of socket.

If you buy a replacement make sure it actually says SuperCharge on it.

Has anybody measured the charging rate of the S8 Plus? More specifically has anybody checked to see how many amps they're charging at?
I'm using the app called Ampere and I'm only seeing a max of 1 amp regardless of what battery percent I start charging at.
This seems really bad considering this is suppose to be fast charging. On the pixel I was getting 2+ amps at all times. On the nexus 6p I was getting 1.8 amps.
Can anybody else also check to see what you're getting. Please post what the battery percent is at when up plug in to charge, and what the app Ampere is showing.
I am using original charging brick and original usb a to type c cable.
When the screen is on fast charging is disabled, when its off its charging at [email protected] from 0 to maybe 70% then it trickle charges.
With standard 2A charger, i can see 1600-1700 in ampere,
With QC 2.0 , am checking the voltmeter and it do the 9v charging,
So nothing wrong

No, i mean any decent 2A charger,
I use my country local brand Hippo, for example, and charging rate is good
The one came with the phone is QC 2.0 that can go faster than normal 2A charger, although it only rated at 1.67 but it's 9V
So this is what I've found out.
First of all the app Ampere only gives charging information for when the screen is ON and not OFF. I uninstalled the app and installed AccuBattery which does everything.
When charging with the screen on the phone charges with amps of 1.3 amps.
When charging with the screen off the phone charges at 2.5 Amps.
Again all original utilities used

This is interesting and annoying at the same time. I had no idea the phone charged at different rates based on if the screen was off or on. my previous htc 10 did not do this and charged fast anytime it was plugged in. while driving and running waze i noticed the s8 didnt charge as fast with the screen on but ill have to try with it off to see the rate. i also installed accubattery to test screen off charging rate since ampere doesnt. thanks

Well I drained to 60% and recharged and on fast charge i got 1.5 amps or 1500 milli
I go off my cable it has never let me down
I have had to many device where the readings of the apps where off
That current cable is pretty accurate most apps I have seen on S8 though
I use it to detect charging problems on blocks,cords,and device Found the sweet spot on my old note 2 with it and made it usable for now again

It variates up and down a bit seems pretty stable till i turn on screen
So I bought a very cheap cable at the 'Action' (a discount store in the Netherlands) and I didn't believe what I saw.... 2.7 Amp, with SCREEN ON. I tested with 3 apps. It IS really the loading amp.
Unbelievable !! THe cable can be inserterd in 2 ways (everybody knows here, USB-C) With the label on the cable up works the fastest. I think charging with phone off goes even faster, till 80 %, maximal 45 min. Is this an update of Android for the S8plus or do I have an extremely good cable ?
I wonder why I am not getting the promised charging speed of 50w?
With the screen off I am getting 26.99w at most.
With the screen on I am getting around 12w.
I charged my fone at around 35%. I have a hunch the 50w will only kick in from 0% up to a certain percentage.
Anybody here observed similar results?
50 w is just for the beginning, when your battery is almost 0%.
The charger is not 50W flat. The charging power will change depending on the battery charge.

I understand your point
but if someone came from 30W charge phone to 50W charge phone
he will expect it to be faster at least, not slower
25W is very good but it is not 50W
I think he is asking to see is it SW bug or HW problem or just a big lie from Xiaomi about how much we should get in real world

Okay, i had both phones, a OP 8pro (30w charge) and my new Xiaomi 10Pro and compared charging speeds and the Mi10 Pro is much more faster than the OP8 pro, it felt it takes hours until the op8 pro reaches 100%. i dont care about measurements, ampere showed me a peak of ~9500ma at peak on the mi10 pro, no idea about the OP8pro on ampere. My Mi10 pro had a 60w charger but i dont have an usb tester anymore, if the phone got a 100% charge under a hour then everything should fine, isnt?
Maybe your USB tester isn't capable to detect the right power of the charger, as i know these usb testers are only able to count voltages from quick charge (1,2,3...)?? But i can wrong here...

he he, thats a funny thing, trust me ...
i bought the oneplus8 pro at relaese day as popup edition (cases and headphones included) 999€ and i used it for a bit more than one month BUT i never was satisfied at all, i mean there was a lot of camera improvements over time but i couldn't understand the hype about the display and when it comes to battery life i was a bit disappointed. (My former phone was a Huawei P30 pro) I had the feeling the battery was draining faster than normal and as i said, i never felt completely happy with the phone. So last weekend i surfed in the web and found a shop in the city next to me that sold the Xiaomi Mi10 pro so i decided to take a look on the phone. And trust me, i saw the phone in the store, played around a bit and i knew immediately thats the right one. I compared both phones a lot and until today i doesn't regret the decision. The Phone is Top notch in battery, display, performance i miss nothing from the opo8pro and i'm lucky that i sold the phone. All i kept from the oneplus was the WirelessZ Bullets.

My point exactly. Notice i never complained about the charging speed. My issue is Xiaomi advertising this to have 50w charging but we consumers are only getting 25w tops. I am trying to figure out why. Will try to charge with the ampere app.

mine charges with like 50w (45-50w) until about 40% and after that it slows down gradually, which is the expected behavior.
this phone changed the way I use my phone completely! I always charged my devices overnight to 100. but now considering how little it takes to charge this phone I just don't think about charging every time it gets to like 10 I plug it in to 80%.
1% to 80% took 33min, 3502mAh
4% to 80% took 29min, 3227mAh

Did you use a tester to conclude you are getting 45-50w below 40%? If so, may I see it? I am suspecting the low reading could be due to my tester.

yup I have some cheapo china testers
the better one (usb c) shows about 45w when charging
the second one (usb a) only allows quick charge 18w because the 65w xiaomi charger uses a half assed usb 3 port (one pin more than usb 2) and
therefore only works if the (usb a) tester also has usb 3 pins. For the same reason if you use a normal usb 2 (usb a to c) cable you won't get 50w
i also tested it again. it charges up to 33% with ~45w and then goes down to ~30w I checked again at arrount 65% it was charging with ~25w. At least these are the values that my tester shows
other values (charge % , time, mAh) in my previous post were readings from the phone itself.

My usb tester is exactly the first photo. Since I got my unit used, it might not have the original cable.
Would you be kind enough to check if on the USB A side, where the cable attaches to plug, does it day 3A?
Also, at what amps does it say when the charged is doing 45w?
Thank you

You can see the extra pin by looking down the port
I marked them in the attachments. Basically it's one of the 5 extra pins that usb 3 uses.
Sorry I have to check again later for the exact amperage, just charged my device. This time i checked the percentage and it charged to 41% with 45w. The deciding logic is probably more complicated than just a percentage.
Edit: added a photo with the exact charge info
the reason u r not getting 50w is bcos u put a meter between the charger and the cable... in order for xiaomi to draw out 50w from usba they put in a small microchip inside the cable to trigger the 50w quick change. if u look into the usb cable u will see extra pin in the middle of the cable, this pin work with the microchip to trigger the 50w quick charge.
solution:
1. always use original cable come with the mi10pro phone.
2. dont plug anything between the cable and charger.
3. if u want to test charging speed with meter, use type-c to type-c meter.
FYi, xiaomi 50w is using 10v 5a.
The phone heats up to 43 degrees during fast charging.
Hi,
for me, the charging speed varies between 50 and 75 minutes for a full charge. It says warp charge 65 on the lockscreen. Any idea, what might cause it being slower than it should be? I am on OOS 11.0.4.5.
Thanks
Mine actually charges faster than advertised. It charges from totally discharged to fully charged in 35 minutes with the phone turned off.

Check to see if you have optimised charging enabled. If you do then that slows down charging.

Thanks, it is switched off. Do you know how much current is used when charging at about 60%? According to 3C, it is between 1,800 and 2,800 mA. Only once, I have seen about 6,000 mA in a similar situation. Somehow this looks rather random to me.
Warp charge is as advertised for me. Any other charger is extremely slow. Gsam shows I'm at about 3400 while charging from 60-70.

I stop paying attention to the current because in the end it doesn't matter what instantaneous current I am seeing. I always see it starts with 5500+ mA for just a few seconds and drop to 3000+. I ignored it and just let it charge (phone on, screen off).
I usually charge from 2x % to 90%, and it takes no longer than 25 minutes most of the time. Averaging 2.5~3% per minute.
Usb cable or usb port of your phone might be at fault.
My 8t takes less than 40 mins even with optimized charging turned on.
Because my phone says Warp charge 65, I do not think charger or cable are broken. I try to avoid uncharging my phone to a low level, so I cannot tell how long it would take from empty to full.
The other observations are like what @zellleonhart is describing. I had just wanted to rule out hardware issues for a new device.

That used to happen to me. 65w would only happen for some charges and other times it would be slower taking over an hour to fully charge. Now it charges fast every single time in 40 mins or less. Not sure what fixed it but I have a t mobile variant converted to the latest eu 11.0.5.6 and optimized charging off. I don't always charge full but the first 15-20 mins being fast seems important imo since that can be done after waking up and getting ready
I think we are all forgetting that we aren't charging one 4500 battery but actually two 2250 batteries at the same time. It legitimately charges from 0-100 in under 40 minutes, I've tested it. The problem is it's not compatible with any other charger I've tried. Quick charge 1,2,3,4 or PD or even the warp 30 from my OnePlus 7 pro. Any other charger I try is like plugging it into a computer and would take 24 hours to charge. OnePlus definitely messed something up and really needs to fix it soon.

My original observation (and this was confirmed by multiple people now) was that using the original charger and cable, charging speed varies a lot and only sometimes had cuurents for a few mins, which could charge in 40 mins if it would be constantly at that rate.
Your comment about slow charges using other chargers unfortunately is very true. I have tries lots of combinations (chargers for Macbook Pro, Xiaomi phones, older Oneplus chargers and cables from 3T) and the fastest of these would need about 3-4h and the slowest about 10-12h (estimates based on current).

My phone has charged at the advertised speeds every single time I've ever plugged in the warp charger. It charges my phone everyday from 20%-80% in 18 minutes. I've charged it from 0-100 in 38 minutes.

Yep this is the annoying part for me. I leave my warp charger at home. My car charger and charger for work charges extremely slow. Most of the time the % doesn't even move.

Meanwhile I have rooted my phone and installed xXx_NoLimits.
Since I did that, the charging speed was always as fast as Oneplus states.
Weird...
Are you using custom kernel? Some custom kernels don"t have fastcharge.

I got warp charger speeds non rooted, rooted, stock kernel, custom kernel, with no limits, without no limits. Warp charge always works for me the past month.

No. Haven't used a custom kernel on this phone yet.
Just tried the 30W Warp charger of my OP3T again after installing xXx_NoLimits and now this is also charging relatively fast. Estimated full charge time is 1:35.
And yes, I understand that for some folks the full speed has always worked
This is the absolute best warp charge magnetic cable I and my friends have ever used. Been using it for years now. Both warp and dash changes and better yet. None of my phones have charging port issues ^_^.
It's about Samsung official 15W Wireless Charger Duo (model number EP-P5400) and is the fastest wireless charging pad from Samsung.
Using the above wireless charger, charging the S22 Ultra(Snapdragon) using the 25W Samsung adapter and the cable(that comes in the phone box) . Started charging at 12 noon when the battery was at 1% and in about 3 hours 21 mins it's charged till 76%, and to fully charge it took 4 hours and several minutes. The "time remaining to fully charge" shown below the battery icon is false, it takes way more(double) time. It does fast wireless charging at 15W, but should it take 4+ hours to fully charge?
This charging adapter+cable combo does super fast WIRED charging and charges fully as intended and on time, so no issues with the adapter+cable.
Phone FW build is "AVCJ", phone is not connected to any bluetooth device or such, there's no metal object in between, fast wireless charging toggle is ON in settings, cache erased in recovery, device care app version 13.0.03.1(is the latest and app cache erased), phone restarted and so on for basic troubleshooting.
What is the issue if not the EP-P5400 wireless charging pad itself?
Bump!
PS: Ambient temperature is low (21/22°C), so it's not about slow charging due to temperature rise in the phone and the cooling fan inside the charging pad is working fine too.

Possible misalignment of the phone on the charger?
Is the fast wireless charging switched on in the battery settings?

This I've already mentioned in the OP.
some possibility is that the phone was doing something in the background that consumed battery while charging... check to see if anything is running in the background, often times it's Google related (some 3rd parties known to drain are FB related apps)
If this is doing all the time then might be something that you'd want to check with samsung. reproduce the issue then report to samsung using Samsung Members app > get help > error report.
Have you tried a different wireless charger. Yours may not be working correctly for some reason.

I did, with a 9W wireless charger from Samsung from 10 to 30% that took comparatively longer time than this new one, which is obvious.
Dpk1 said:
So, today it charged from 53% to 100% in just 55 minutes. Phone wasn't used while charging and 4G data bluetooth were on like before. Charging was done at similar location of the same room as before. The difference was that I used Samsung 25W adapter to power the Wireless Charger (instead of hp one) and kept the charger over a flat wooden rack (instead of over bed mattress last time).

Charged from 53% to 100% with the above "conditions" met using the 25W Samsung adapter. Started charging at 9:40 AM and done at 11:11 AM, that's 1 hour 31 mins.
What's the device care version you are using?
Just for a test unplug the pad from the charger and hook up direct to the phone with cable. How long does it say for a charge now?
I have the 15 watt Samsung Charger that comes with a 25 watt super fast charger. 15 watts wireless and 25 watts when wired. EP-P2400TBEGUS make sure when buying the one I have that it comes with the travel adapter (Charger). They sell two versions one for $39.99 that is just the pad only and then the one I have for $59.99 that comes travel adapter (Charger)
Anyway I am currently at 45% let me put it on charger and see how long it says it will take to charge to 100. Ok it says 1hr 9min to fast wireless charge to full.
Now I plug in the cable direct to the phone and it says 45min to super fast charger to full.
There is no way phone shoukd take hours to wirelessly charge unless there is a problem with the pad, charger or case interfering with wiress charging.
What case are you using? Are there magnets on it? Is it very thick material?

Hence, charged it when phone was turned off, "gain" was some 8 mins less time to fully charge. So the problem lies elsewhere.

Wait I missed that post above. You said you used an HP Charger and a Samsung Charger on the pad but the Samsung wirelessly charged in an hour and a half wirelessly? What's wrong with that?
Also where and what is the wireless pad sitting on? Wood Table or Desk? Not a bed?

I just did 33% - 100% in about 1 hour 18 min which is pretty normal for 15 watt fast wireless charging. The same Samsung 25 watt charger plugged in wired will get you there under an hour. Don't use third party chargers with the wireless pad. Just the Samsung 25 watt one. Really nothing wrong with 1.5 hours wirelessly. These are normal charge times.

Yours same one does, mine does not same way wirelessly like yours. That's the problem. Nothing else.
After about 80% the charging rate ramps down to protect the battery.
At about 90% it will ramp down again and likely yet another time as it approaches 100%; this is normal. New batteries have a higher capacity and will charge longer.
Peak charge rates occur between 6- 72% or so as long as it doesn't exceed about 102F.
Fast charging will not engage for that charge cycle if the start temperature is below about 50-60F or less to protect the battery.
Ideal start temperature is 82-90F, charging is an electrochemical reaction that needs enough heat to function at optimum fast charging rates.
Provide cooling as needed as temperature approaches 98F.
Other possible causes are a defective temperature sensor in the battery, mobo or charging coil. Firmware; corruption or wrong values. A defective coil assembly, C port pcb or mobo.
