Fast Charging?!?

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.

How to measure charging rate even when the screen is off on S8 plus ?

Hi, I got the S8 plus verizon version.
I suspect I have fast charging issue. The phone doesn't seem to do fast charge all the time even when the screen is off.
I want to know if there is an app that can measure the "overall" charging rate from start to finish when the screen is off. I tried Ampere, it is good app, but it only shows the "current" rate, which very often is around 500mA to 700mA on average on Samsung original charger. Yes, it does occusionally go up to 900mA or 1020 mA. But never over, on samsung original charger. It is normal? I remember I used the Anker charger with QC, it shows it went up to 1680 mA ... However, when I do it now, it does not. It caps on 1020 mA.
Sometime even worst if I a QC car charger, at around 300mA .
When the screen is off, there is no way for me to see the charging rate. If QC is not working, is the phone has some minor defect? I should sent it for repair ?
Please let me know if I have other ways to measure it.
(Thanks in advance.)
Note:. Yes, I also experience some screen shut off or no powering on issue like some members here.

Although not an app, this works great as it shows the charging voltage as well as the current.

Question What's causing this(Samsung Wireless charger EP-P5400)?

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.

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.

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.

Question S22 Ultra Android Auto Battery Drain

I'm wondering if anyone has run into the S22 Ultra problem where the battery drains faster than it can be charged. I'm using Android Auto on my car's screen, so AA is active while I am driving and navigating. The S22U's screen is off. It doesn't matter if I am using wireless AA with a phone holder with built in 15W wireless charging, or wireless AA and the phone plugged into an AC fast charger, or wired AA with my phone plugged into my car's USB C port, the battery on the phone will actually drain faster than it can be charged. I did not have this problem with my S21U. With that phone, after a 3 or 4 hour drive, the battery would be at 100%. With the S22U, it would never reach 100%, but be at 75% or 80% at my destination. Is Android Auto that much of a battery hog on the S22U?

Using my S22 Ultra U1 with wired AA always charges my phone to 100% long before reaching my destination. Using wireless is another story. Did you make sure your fast charging settings are on?

Yep, fast charging is on. And I'm using an AC charger that says "Super Fast Charging 2.0" when on my house current. Could be limited by the AC power plug in my car, but it should still charge faster than it drains I think.

Make sure the charger is good and it's power source as well. Use the correct Samsung cable, limit length to 3 feet.
If the device is drawing too much current the power controller will ramp down the charge current to protect the battery.
Some apps can run with the display off without skewing the charge curve if they don't draw too much current. High battery temperature can also cause this.
It could be a glitch or error in the firmware if the current draw is actually low. Or maybe it part of Samsung's new thermal paranoia. Sammy's just full of rude surprises lately...

The car inverter could be interacting with the brick's switching power supply or the power controller.
Fast charging with disengage if the preset conditions aren't met and maintained.

Charger and cable should be OK. Next time I'm on a long drive I will check the power draw. I have a cable that tells me how many watts is being drawn.

Charging issues can be hard to troubleshoot.
In general these devices shouldn't be charged while in use. The most I'll do is sometimes listening with the Buds+ using Poweramp. The N10+ will tolerate this.
Google Services and such tend to use a fair amount of power as may the modem especially if switching between cell towers.
Once fast charging disengages it likely won't reengage unless the charging power is cycled.
So one high current usage spike is all it takes.

Agreed, I've used 65 watt A/C chargers in the car outlet before and work pretty much the same as in the house. Strange that your phone is behaving this way. I have a 2021 Bronco Sport and the wired (usb-c) is plenty strong enough to charge the phone while on AA. The previous Subaru was questionable at times but usually pulled it off on my S21 Ultra. Any way you can check the charging voltage /amperage while using you phone in the car?

Can you please show which 65 AC charger you are using for car? Thanks

The same it's for me, but I noticed that if I rotate the cable the phone will not drain anymore, I know that's weird, but this is the behaviour...Sometimes it's working, sometimes it's not... It depends also if I'm using Waze+Youtube, or only Waze

I've encountered this too. If I plug in a cable one way, charges slowly. If I flip the cable 180°, it charges normally. This also happened on my Note 10+ 5G, and I've seen it happen on my daughter's S22 and S10. I think it is a cable problem, because with some cables I have this issue, but not with other cables. Not all USB-C cables are created equal. Also not all car USB ports or chargers are created equal.
I normally use wireless charging and connect to my car via BT though. I have an iOttie wireless charger in my car and haven't run into this problem. I have it mounted so that an A/C vent blows on the phone to prevent overheating from sunlight. I use Waze and Samsung Music regularly.

I have purchased 3 Port 65W charger for s22 Ultra & its charge Super Fast but there is didn't mention anything about GaN, If it won't have GaN then does my charger is useless?

I have a 2020 Honda CR-V and plug it in wired to the USB port and it charges fine. Doesn't drain or anything. I also have a Weather tech phone cup holder where the Cup is sitting about 8 inches in front of the charge port. So I got the shortest braided cable I could find for neatness which is 18 inches in length.

This should not happen unless there's a problem on your phone coz my phone always charges faster than drain and stays at 100% with power bank only(no fast charge), using navigation map and spotify.

Not a desirable configuration...
The higher the cell voltage and temperature, the faster an Li degrades.
Li's prefer frequent midrange power cycling as opposed to complete charge cycles or the worst staying at or near a full charge state.
If the display is on it's typical behavior for charging to ramp down even stop in order to protect the battery.

Question Wireless charging times

Hi all, I've had my pixel 7 pro for just over a week now and love it.
The only frustration is wireless charging. I've got 9w and 10w wireless pads. With both, after an all night change it barely charges 50%. This is with and without a case. Also, the phone does not change in my car at all (BMW built in charging pad).
My s21 ultra would charge is less than 4 hours.
What are you all experiencing? Is my phone faulty?
Thanks!

Encountered similar with wireless no name pad. Would go to 68%, and lot of heat.

Nice to know. Was trying to get at least a 15w pad, but don't know about heat. Is the google wireless stand the only one good for this?

Make sure you are using a Qi EPP charger.
My old Samsung wireless chargers don't fast charge the Pixel either

Thanks for the reply! What I'm experiencing is not even fast changing, 50% in 8 hours!
How long does yours take to charge

Im still using the wireless charger I bought for my OnePlus 9 Pro. Works perfectly, charges to 100%, and fast charging

Try a USB current device, in-line with the charging pad(s). PortaPow makes a good one, and there are some cheap-ish ones out there, you sort of have to be selective.
f you do, you'll find that some do pull an actual 10(ish)A, while others don't even come close.
The OP charger is a good one, I had a well-ranked 10A charger before, and currently a Pixel Stand. They all charge the phone quickly, IME/IMO. Quickly enough for me anyway, that part is pretty subjective, again IME.

Thanks for the responses all!
So what times are you all seeing with your chargers? and what chargers are you using?
It'd be great to hear from those that use a samsung qi charger (9W trio charge pad).

My P7P will charge fully in about 4 hours, using 10A wireless, the handful of times I've needed it.
I'm more typically charging from 50% or so, seems like, and that takes a couple of hours. I've been using wireless charging for a bit over 10 years though, and it's far handier than plugging in, IMO.
Obviously, if your lifestyle needs are a 35 minute charge from 50%, then wireless isn't going to be so appealing.

Does it generate a lot heat during the cycle?

Nope, or it's not appreciable anyway. It's charging right now, has been for a bit this AM, and it's a hair warmer than the air around it, if I lift it away and touch it (the case, it's got a decently thick Spigen case on it). I'd guess maybe 10 degrees warmer than ambient (I could rustle up my surface temp tester, from the garage, I suppose... ).
