To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Poco F2 Pro (Redmi K30 Pro) can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
With the supplied charger and cable the charging time is very impressive ("Turbo Charge") with a normal QC3.0 charger charge time is still very good but comparable to most other QC3.0 devices.
Something to note is the device does get noticeably warm when using the supplied charger in the "Turbo Charge" mode.
Takes about an hour for me with included charger.

yes i noticed it get warm to hot-ish
isn't that bad for the battery?
moreover i noticed that if you charge while turned off it does not get hot

That's normal because you're not using it, if using while charging it will be hot as your running apps, tasks etc... at the same time. This will increase the heat as sensors will be running also.
Has anyone tried to use other cables that has the same turbo charge effect like the included cable? The included cable is too short, usually I use 2 meters long cable.
I have tried the baseus 5A 40W cable but it only support quick charging and not turbo.
I've tested charging wattage using original 33W charger and original USB cable via specialized USB tester, and I noticed it provides only 25W (about 9.6V/2.65A). It shows "Turbo Charge" indeed, but it's still only 75% efficient. Anyone care to explain this? Is this normal? I've read that only Zoom edition can be charged at 33W, so I expected non-Zoom edition will charge at least with 30W. I tried two other USB cables, and still only 25W. Later today I will try to charge it with Blitzwolf 30W PD charger and see how it goes with that one...
I haven't really tested charge speeds. So far the battery life has been exceptional and the main reason I opted for this phone without the high res screen and refresh rate, as see battery as more essential. I would much prefer charging at a slow speed to preserve battery life. A good app for this is AccuBattery. It measures how many mAh's being charged and discharged after each charge and keeps a graph. It will estimate battery health also.
Yeah I know about AccuBattery, I've been using it in the past. But a real physical tester device is always more precise. I do sw/hw development for a living so I know for a fact. Indeed, battery life is very good because optimized MIUI and pretty big battery, but it would be even better if charging speed was also up to the specs. Meanwhile I've tested charging speed using Blitzwolf 30W PD2.0 charger (K30Pro should support PD3.0 and be backward compatible), and situation is even worse - only about 15-16W at QC3.0 I believe. So no Turbo Charge was initiated. I mean 25W with original charger is still good, but I expected advertised charging speed. I'll do more tests when I catch some time.
Thats normal, because it don't charge all the time with 30W. Compare it with WARP Charge 30T it is faster. OnePlus 8 got 30W and 4300 mAh, F2 Pro is faster with bigger bettery but it's almost the same.
How old is your Blitzwolf charger?
I know it shouldn't charge @30W above 80-90%, but sure it should at 20-ish where I'm at about now. It's also not even cool to the touch, so there's no apparent reason to slow it to 25W. My Blitzwolf charger is about a year old, but I only used it couple of times, so it should be as good as new.

Batteries don't like heat but it is actively monitored and it will slow down charging when it crosses temperature threshold.
That's why I mentioned my phone is not even cool to the touch (let alone hot), so my case is not temperature related. I'll try to charge it while turned off, though it was pretty much in idle doing nothing when I did the test, ie. not stressed at all by any factor. All in all, I mean if everyone else gets 25W out of original charger, I won't bother anymore. Also, if it charges from 10-90% in around 1 hour, I won't waste any more time on this either, since it's good enough for me. I was just curious why it charges at 25W, when 30W (and 33W for Zoom edition) was advertised. Altough it wouldn't be the first time something was advertised at launch, and not achievable in real-case scenario.

Fun fact: phone doesn't charge when powered off?! That's a first. Is it just me, or am I getting too old? For the whole time I'm talking about my Redmi, not to confuse it with Poco, if that matters at all. Maybe Poco works differently.
On my Huawei device you also can not turn off an charge but this starts with Android 10.
takes about 1 hour and 20 minutes for me, I think the high temperature here, summer season, is the reason for this slow charging speed.
From 20-100% in about an hour. Few minutes less actually. Battery is big, that's all ok.
F2 turn off and are dead with 0% (can't turn on). Timer 60 min. and after 60 min. I got 96% with original charger. The phone don't turn on, like it always do.
@Burs a friend told me "on my Anker charger I only can use PD over the third usb port, with the type c port it will charge over QC 3.0 and not over PD" maybe thats why you get ~16W?
When my Redmi was turned off completey, it was hooked up to my USB tester for about a minute. I doubt it would trigger after some minutes, and only then start charging. For the whole time it was connected, I was getting 5V / 0.015A readings on the display. That's pretty much USB tester drawing the power from the phone battery, not the charger! So that would mean charging was completely disabled making the phone behave as a power bank lol. Weird enough, right?
My Blitzwolf charger has only two ports. One PD2.0 (USB-C) and one QC3.0 (USB-A). I've tried three sets of USB cables (one even 5A) on both ports, and best I could get out of it was about 15W. I think I'll have to order another one with PD3.0 and Turbo Charge compatibility.
Heh I'm planning on just using my old 1A slow chargers because they're dotted around the house and work, will probably not even plug fast charger in. Magnetic cables are just so convenient.

Has anyone used a hand-cranked charger? I have a Brookstone hand-cranked flashlight/radio that can charge phones. I'm considering getting an adapter to charge my Tilt but I don't know if it can handle it. It says it can output up to 600mA. I've heard bad reports of other chargers with dumb phones but nothing of this one. It seems unlikely this can keep a power-hungry Kaiser charged. It also outputs 6 volts. I hope this doesn't fry the phone.
Edit: I meant 600mA
Any estimates on how long it would take to reach full battery charge?
A couple of hours?
Excellent for weight loss, especially if you use 3G...
The standard Kaiser or Hermes wall charger is rated at 1A (1000mA), and a powered USB port outputs 500mA. As some people have problems charging from USB - particularly after completely discharging their batteries, then I'd think that 500mA is the minimum power required to charge.
If you install one of those programs which displays battery power you'll probably find that the power draw is much higher than 6mA (even in standby) so all you'll do with the hand cranked charger is slightly reduce the rate at which the battery is discharging.
Looking at a 1350mAh battery, this would take a minimum of 9 days and 8 hours to charge the battery from flat if it isn't being used - great workout but hardly worth it
I got a cheapo one from some gareg... AA branded thing for a fiver, flash light thingy to... five mins of winding gave a one percent increase in battery, but then if your really stuck it could be a good thing... only cost a fiver too!
Hi everyone, I'm looking for more info about the fast charge function of the Note 4: I can read on the charger that it either provides 5 on 9V. Does this mean that I can supply 9V on the USB port to fast charge my note 4 ? Does anyone know how the charger detects wheher it it should supply 5 or 9V?

Yes, it means that that charger will deliver power at 9 V (at 1.67 A) to the phone.
As for how it decides which voltage/current to use, it'll be as a function of the battery's charge level, temperature, and probably some other factors, but that's getting into some very specific settings for the phone/charger system by that point.

thanks for the quick reply! I've got a couple of Dc Converters (buck) and lipo batteries (11.1V) and was wondering how the phone signals the charger it can accept 9V and if I can use my DC step down to feed the phone with9V...
I guess I will have to try

I agree that it might be damaging to the battery (but obviously not extremely damaging). Why else would there be the option to switch off fast charging? I've switched mine off anyway because I have no use for it as my phone charges overnight and makes no difference how quickly it gets to 100%.

I personally thought the option to disable Fast Charging was Samsungs' way of reminding us, or letting the uninformed know, that it can do it.
The generally accepted rule amongst radio control hobbyists is that provided the battery is well made, it's not the current that'll kill a battery - it's overcharging it (over 4.2V per cell on a LiPo). Provided that the charging circuit is good (and I have no doubt it is of a high quality) we shouldn't see any degradation in battery life when used with the fast charge process.
Others may chime in with more info, but that's how I understand it.

l believe the fast charge is safe for the battery as it charges it at 1C (=1hr charge) which is actually not so fast.
Here is my tip: I have an old charger to charge overnight and use the mote 4 charger only for fast charging during the day (I leave it in my bag). I'm actually lookingfor a way to make a fast charging battery bank.
So here is my question again: has anyone tried supplying 9V to the phone ?
best device in charging
its charging up the whole battery in about an hour, i really like that and the battery gives me a full day
So far right now i can talk for about an hour and play games for about an hour and leave it on overnight and all day and still have 82% left. I'm super impressed!

YOAH!!! Thats insane!
I know that the amperage on the charger is huge in its speed.
I used many custom Roms and kernels in the past on other phones with fast charge. I used several chargers and always charged much quicker with higher amperage outputs. Some were as low as 300 MA to as high as 1.2A. This is why the amperage is so high on this phones charger. The voltage is needed to push the charge quicker. Good luck finding high A charger at 9v.
My 1.2A charger i use as backup is much faster then the 500/700ma ones I have but they are all 5v and can't compete with fast charge.
Sent from my *ROOTED* Note 4 SM-N910W8
I'm also looking for a power bank that would be able to charge at
- 5V 2A,
- 5.5V (Galaxy Tab S)
- 9V (Note 4).
- with 2x18650
- able to charge itself fast too;
- charge-through (charging a device while changing itself).
i now have this ENB model, but it does not deliver 2A to Tab S (and charges at 5V not 5.5).
And it charges itself with 1A even from 2A-capable power supply.
Hi all,
I notice something that the note 4 does not charge fast after I installed S-View cover (original one), although an indication appeared that it is using the fast charging function.
I guessed it assume that the cover is open and charge slower. However, if I removed the S-View it charge noticeably faster.
Do you think this a bug in firmware ??
Thank you,
The so-called USB fast chargers query the device to be charged. Devices capable of fast charging at 9V DC have additional circuitry in their USB ports that the charger can detect. If the charger doesn't detect the circuitry, it falls back to 5V DC mode, like any other USB charger. Assuming the fast charger is functioning correctly, it should not over-charge an older phone or tablet that doesn't support fast charging; it will simply take as long as the original "dumb" USB charger did.
So yesterday I bought a 2.0 charger off of amazon with the choe brand name. According to the ad it works with nearly every android phone, including the HTC one m8. For the past year I have been using a charger from my last phone which was a crappy flip phone and thought nothing of it, but I am wondering does this charger truly work?? According to app "Ampere" it is much slower. Also, I've read reports about phones heating up and that's what mine did last night, is that normal? How long should it take for me to full charge my HTC one m8?
It will heat up, that is normal. It'll use most of its 2.4A between 20 and 70% and then slow down. Your total charge time shouldn't take more than 1 hour, and make sure you're using the supplied cable.
Thanks for the response! So if it doesn't charge 1 to 100 in 1 hour than is something wrong? Also will a charger like this have any effect on how long my battery lasts? My last charger for whatever reason was for my last flip phone believe it or not, I never bought a new one.

no I wouldn't say that.
my 2.0 QC will get it done in about 1-2 hours compared to the 3-5 or so it took with stock charger.
0-100% will take more than an hour. I've timed mine a few times from 0-100%, not using the phone at all and in airplane mode waking it up every 5 minutes to check percentage, volts, and charge rate using Gsam batt monitor.
Comparing the two chargers (OEM HTC QC 2.0, and original HTC charger- which I believe is QC 1.0) the QC 2.0 is definitely faster. Even though there is nothing on the phone telling you it is using the higher wattage charging mode, it is. So, 0 to 100% using HTC's QC2, usually takes around 1:20 minutes if I remember right. As in the other post, it starts out rather slow to around 20%, then kicks in to high gear until around 80%, then slows back down all the way to 100% so as to not overcharge the battery and harm it. It really is amazing the speed that it charges at. It does get rather warm, which is normal, but shouldn't hurt the phone.
Now, completely draining and recharging these batteries frequently is not good for them and will decrease the useful life sooner. Keeping it somewhere around 80 % is ideal but realistically not practical and the manufacturers know that. That's why they build in overcharge circuitry protection so leaving the charger on all the time "shouldn't" harm the battery. Draining it down to zero and doing a full recharge cycle on it frequently WILL decrease the lifespan. The batterie's useful life is basically determined by a finite number of charge cycles.
There's tons of info on charging and batteries out there if you are looking for more reading too.
Anyone heard of the brand Auzen? It's popping up alot on aliexpress and around asian market. Not too much reviews yet on that brand.
don't play with quick chargers .I bloated my m8 batt once trying it .it charge at 2.4a .our device max is 1.5a.
If you insist using it then don't full charge with it n monitor closely .
That's impressive, I use a QC2.0 car charger, I use a variety of wall chargers that run from 1.0A to 2.3A at 5V.
So far, my battery is still very happy.
Sounds like you got a cheap knock off charger or your battery/charging circuitry was damaged/faulty and/or your ROM/firmware weren't proper, for that kind of damage to occur.
I don't think Ampere works. I once did a test (last month) and had 6 different USB cables and I wanted to see which was the best, every time I used one I got a different reading, from 200 up to 1600. Even using my Anker Quick Charge 2.0 I only got 400 so it stated.
I have been using Aukey QuickCharge 2.0 and gives pretty decent charge times.
I have a QUICK Changer 2.0. works great.. have some tips...
You know there is some colors on cable conectors ends you have to choose the right one..
- If the cable is not a quality one can result to slow charging.
Black ----- 1.0. most in stock phones
White------ 2.0. the right for fast charging...
The time on reaching 100% on battery,well Quickly charger 2.0 will reach 80% on your battery fast and it will change the next 20% slower...
There is some app in playstore can help can see the amperage live in mA..
Connect your charger to get the battery charging current or disconnect it and get the negative discharging current... and you can see your battery charging current mA is constantly changing because even on charging phone still using current (negative discharging current) and this is always changing.
On my case I see higher mA reading only under really low battery...
I have a problem with my m8 and aukey 2.0 quick charger....
After firmware update to 6.12.xxx.xxx mm , the app ampere tell me max 1600ma before update its tell 2000ma .. Its a bug or a feature of the new firmware base...??? I have cyanogenmod 13
Im using the same aukey 2.0 quick charger. Works perfect.
M8 is 1.5a max .if you use 2.0a logically you're overcharging it. Just wait for it to get bloat n replace the whole bat. worth it ?
Hi, i just wanted to say something. After many bad chargers i bought, i found the Nillkin chargers (2Amps)and Nillkin cables (2.1Amp) the best and best quality. I am always testing with good Usb voltage tester and it can charge up to 1.5 amps max on M8 and on LG G3 1.8 Amps. As long as the charger is 5.0V, amps can variate and it doesnt hurt your battery, it just charges slower or faster. In my case its charging 1% per minute on both phones. It doesn't matter if the cable is black, white, green... cables must be thick, around 18AWG that support high ampers which mean faster charging. thin cables are sh!#. And for car i also found the Scosche dual charger great for every device with Nillkin 30cm cables and Kenu airframe holder.
You can use 2.4A chargers on M8 without problem as it will only receive 1.5amps.

I'm using Anker PowerPort 1+. It's very good and you can use for iPhone iPad & almost Android devices.

That logic is incorrect. The phone will only draw as many amps as its rated for (1.5 amps) regardless of what the charger is rated to supply. Think of the charger amp rating as the "maximum it can supply" instead of "what it will always supply".

Ampere shows max charge rate for me at 2000ma. Where do you get the idea it will overcharge?
So few days ago got the phone , but always charged it through USB port. Now finally tried turbo charger and it definitely isn't "turbo". I know most of those Turbo claims what I saw were just selling strategy , but I'm pretty sure I'm not even getting 1% - 1 minute. Latest Marshmallow OTA.
So , on a relatively new battery , how fast does your phones charge ? You can write with phone turned off and on..
Also looking at the charger it says for output :
Standard output :5V =1.6A
Turbo output :9v=1.6A
Turbo2 output :12v = 1.2A
This deosn't make any sense to me, while raising volts may solve some power losses through cable , amps are what charges your phone faster or slower , and 1.6A , isn't really a big deal not to mention 1.2A. Reading somewhere that quick charge 2,0 supports up to 3amps draw..
I have One Plus one and it's original charger is 2.1A (quick charge 1.0 ) , with custom kernel bumped charging rate all the way up and good cable I'm seeing about 2Amps of charging in real life , or little more than 1% per minute . I was expecting motorola to charge faster or at least even , even though they are 3100 vs 3900mAh batteries.. Not to mention I can easily mod OnePlus One and get same SOT and battery overall as motorola's, while on motorola I'm stuck with stupid locked bootloader . Original idea was to sell OnePlus One because of Motorola, but I don't know now anymore..
The volts and amps listed on an electrical device are typically its max or rated output, NOT what it "always" delivers. That being said, most power supplies will deliver their rated voltage most of the time, but the current is determined by the charged device (through it's effective resistance)... so as long as you run below the rated current, you'd be fine.
Secondly, from what I'm reading, the OPO doesn't have quick-charge technology (ref: https://www.reddit.com/r/oneplus/co...lcomm_quickcharge_20/?st=ix64k1gy&sh=6d7492c9 ) so I'm not sure what you're talking about there. Again, the charger may say 2.1A, but that doesn't mean it's actually delivering that much all the time. I have a relatively old Kindle Fire with a 2.1A charger, but I know it doesn't charge very fast even with that device.
If you want to talk about Volts and Amps, you need to use actual volt/amp meters to see what you're getting.. Note, there is an app for Android (called Ampere) that claims to report amp-rates, but it also has a caveat saying that the current should not be taken as completely accurate, for various reasons.
Lastly, note that QC doesn't actually run when you are at higher charge levels... I think it's above 80% or something? After that level, it returns to "standard charging" mode for this "top-off" phase of the battery charge cycle. So, if you're seeing slow charge rates there, it's to be expected.
The Turbo has a relatively massive battery. Mine takes...somewhere upwards of 3ish hours on turbo charging to replenish.
1 hour 15 minutes
that's what it takes to go from 0 to 100% using Turbo Charger 2.0
Thank you all for answering, this is exactly why I started this thread. Already see here some interesting results!

Thanks! Actually, OnePlus ONE DOES have quick charge 1.0 which is 5v up to 2.1A. Snapdragon 801 supports quick charge 2.0 but OPO didn't implement it with phone. There are billions of topic on this at OPO forum and a lot of people done tests including myself. The problem with OPO is it's very sensitive on cable so it works best with OEM cable and it somehow recognizes it. There is app called OPO charging current so I monitored with it and synapse . Kernel setup hardware to be able to recive very max 2100mA no mather which cable. Stock ONEplus charger. Some cheap cables gave me from 300 - 600 mA max with screen on . I found at home some cable that looked cheap but said charge only, tried and it charged around 1600mA with screen on and around 1800 screen off. Later got Anker 21 AWG and results were even better , aroun 1800-1900mA screen on and close to maximum 2000mA screen off. Phone was charging 1% in less than a minute. Thought turbo can charge at same rate. After all , it's "boosted" lol.
I know it doesn't do quick charge after around 75% , I tried at 30%. Given all that , 1600mA which is maximum I see on the Motorola's charger is not something special if we disregard Voltage..

Because if you charge from 0-100 in 1h 15min, thats around 3.2Amps charging current , while our buddy Einsteindks here gets around 1.3Amps and max amp I see on "rola's charger is 1.6Amps. I'm confused now.
Also can somebody post picof stock droid turbo USB cable shipped in bundle? I think I don't have stock cable, it says right at the plug phone side "be hello". No other labels or anything..

Kernel setup hardware to be able to recive very max 2100mA no mather which cable. Stock ONEplus charger. Some cheap cables gave me from 300 - 600 mA max with screen on . I found at home some cable that looked cheap but said charge only, tried and it charged around 1600mA with screen on and around 1800 screen off. Later got Anker 21 AWG and results were even better , aroun 1800-1900mA screen on and close to maximum 2000mA screen off. Phone was charging 1% in less than a minute. Thought turbo can charge at same rate. After all , it's "boosted" lol.
I know it doesn't do quick charge after around 75% , I tried at 30%. Given all that , 1600mA which is maximum I see on the Motorola's charger is not something special if we disregard Voltage..
Again this is very interesting. Already here we see 2 totally different results with one being almost as double fast.. Sparksys , you are on stock charger and stock cable?
Because if you charge from 0-100 in 1h 15min, thats around 3.2Amps charging current , while our buddy Einsteindks here gets around 1.3Amps and max amp I see on "rola's charger is 1.6Amps. I'm confused now.
Also can somebody post picof stock droid turbo USB cable shipped in bundle? I think I don't have stock cable, it says right at the plug phone side "be hello". No other labels or anything..

I was guess-timating. Been a while since I've done the full recharge.

According to your guess-timate and max rated power I see on the charger, that seems about right and realistic guess BUT there also isn't anything TURBO about it. I'ts the average charging speed of every device today (1.5A) which doesn't have any kind of quick charge option. Even quick charge 1.0 is faster with 2.1A at 5v . Thats why I opened this topic, I'm confused.
Only voltage is higher on turbo charger than let's say my OPO charger but amps are lower and voltage doesn't have that much of an impact on charging speed, amps do!
When I have my Turbo in my truck at night, and running about a dozen things at once, in addition to all the background stuff, NO 'regular' charger can keep up with the power demand, and the battery undergoes a insanely slow discharge. By itself, the battery lasts 3 or 4 hours, tops. With the turbocharger, the battery charges at a modest rate, maybe 10% per 30 minutes...while under high demand.

That seems ok.
I encourage others to post their charging times so we can compare!
Thanks
Since no other turbo users jumped in...
At the time of starting the topic I have disabled some Verizon's bloatware (completely stock, locked turbo). After reflashing completely stock FW , and with untouched software, droid really did charged turbo fast. More than 1% per minute and around 0-60% for 30min just as advertised for quick charge 2.0 . So if anyone was wondering, that should be benchmark.
On the other hand, phone is almost impossible to charge with any other type of "normal" charger..
My Turbo, running stock MM/root/Xposed with a large load of apps, will charge 20-30% per hour on a normal 1A charger, while lying on the desk with the screen off. It charges at a similar rate via Qi wireless charging. This is plenty for daily overnight charging. My usage habits are such that I usually have 20-40% battery left when I get home from work in the evening.
In a different usage case, when I play Ingress (a real battery eater, screen on + 3D animated graphics + GPS + data) the Qi charger in my car holds discharge to about 5-10% per hour.
I've never had a turbo charger to compare, but I've never found the normal charger or Qi charger to be significantly lacking.

Right, I've also used "normal" charger before. Now, I have all QuickCharge plug chargers -- but I still use Qi wireless charging every day, as does my wife.
I also plug in via USB port on my computer and it charges fine.
okay the way the turbo charging works is that it's like a tier system at very very low charge percentages it works the fastest and slows off after about 60 or 70 percent it just charges like a regular charger all the magic happens at the lower charges. another thing is that unless the cable you are using is total garbage it won't matter at all. it is all the phone and the ac adapter that do the work any variations in the cable will be negligible. I am monitoring my battery through the custom kernel (bhb27 and its app) and it says right now at 81% charge on a turbo charging that I am getting +1172.x mA if my battery was lower this value would be much much higher
lastly I recommend only using the turbo charger when you really need power quickly. if you are just plugging in your phone for the night it makes no sense and will actually be bad for your battery health. the faster it charges the more it heats up and heat is not good for the battery health when I plug my phone in at night I use a .5 amp charger and my phone says that it will need like 8 or 9 hours to charge (this may be exsessive but the quick chargers heat up my phone a lot I also use a 1 and 2 amp charger nearby
I have the Samsung 25w charger, and when using it it appears the phone will only either cable charge or superfast charge. It wont also fast charge. I want to maximize the battery life span of the phone, and cable charging is inconveniently slow, and I figured that fast charging would be a happy medium between that and maxing it out. I was under the impression that it's the phone that dictates the rate of charge it will accept from the brick, and the brick only determines the maximum deliverable current. If I understand correctly, we can use samsung's 45w charger, but the phone will obviously only allow 25w from it. I'm puzzled why when using the 25w charger the phone can't just accept 15w when set to only fast charge. Is this a bug?
Hi,
You might plug in your phone, Go to Parameters, Section Battery, Advanced Battery, and activate Super charge and superfast charge in order using fast and supercharge with your 45W charger !
Yes, I've done that. The 25w charger will only super fast charge, but won't just fast charge. I would have thought it could either one, whichever I have it set to do.
if you want fast charge ..... deactivate superfast charge should be the solution ! Isn't it ?
Probably a firmware/software glitch.
Fast charging will not enable if battery temp is too low.
To avoid Li plating the battery temp should be a minimum of 72°F or higher, the preferred minimum is 80°F.
Using the 45 watt brick may shorten battery life.
Fast charging with the 25 watt brick appears to do little damage.
Li's prefer brief, frequent midrange charges ie 40-65%. Avoid discharging below 30% and charging beyond 90% although 80% is a better top limit.

No, if you only activate fast charge (with superfast deactivated) and use the 25w brick, the notification in the shade says cable charging, and that takes like 2hrs to charge the phone.

That doesn't sound like fast charging is active. It should gain about 2%@minute through most of its range except the top end where it goes to about 1%@minute.
When this doesn't work correctly it's a true pain to troubleshoot. My 10+ started dropping out of fast charging prematurely. A new 25 watt brick/cable and trying a lot of other remedies still hasn't fully restored it.
I'm curious if anyone here has a 25w brick that could confirm if this behavior is present globally, or if this is something just on my device? Only activate fast charging in the battery settings, plug the phone in with the 25w charger, and look in the notification shade and see what the charge rate is tagged as. I'd be grateful if someone would confirm this.

I have noted that you practise the same charging procedures as I have done for several years (and you obviously have done as well). With my Note9 and S8 + I used to not let it drop below 40% if I can avoid it and also not go above 80%. All this is fine and most of this we all probably learned from Battery University and Isadore Buchmann. That all said, and I am really not sure if I am keeping this phone - Decision today or tomorrow - my question comes to the matter of calibration. When I received this phone some 14 days ago I charged it to 100% but thereafter did not run it down to zero but kept it above 40% the whole time. The question I put to you (and others can learn from your response) is there a need to "calibrate" the device initially (ie run down to say 10% for example once a month) as was suggested by Buchmann probably a few years ago?

You and I discussed this earlier. Do you think it is the port that has become damaged? Part of the reason for my getting the wireless charger is my Note 9 is very erratic when it comes to fast charging. Cleaning out the port with a toothbrush/compressed air. rebooting...wiping cache partition, new cable etc never truly fixed it for me. I do feel that when first plugging in the S21 ultra (before going wireless) the connection seemed a lot firmer.

It does appear to be related to the Samsung 25w brick. I have the one that came with my S20U. It will "Super fast charge" my S21U no problem. If I turn off super fast charging in the phone, it only says "charging" when plugged in, and with my phone @ 65%, it said it would take well over an hour to charge (forgot the exact time). Then I took my phone w/o changing any settings to a generic 18w QC3 brick, and it said "fast charging", and said it would take 44 mins to complete.
Ive seen this same type of issue as well with 2 different chargers. One charger (45w pd) will fast charge with super turned on but not fast, notification only says fast charge. The second (39w qc3) will fast charge with regular fast charging turned on, but turning on super does nothing. Charge times are the same with both chargers on regular charging and fast, with 0 differemce between fast charging and super.

I'm as clueless as you at this point unfortunately.
My port is good, cable/charger, tried hard reset, cleared system/akp caches, did the recall thing and so on.
I'm wondering if it's a battery fault. Do older batteries go into fast charging the same as newer ones? It's almost as if it's throttling the fast charging, sometimes it's full bore then it drops out to 1%@45 seconds then to 1%@minute.
Or is it a calibration ie it thinks it's at 90% when it's only at 70%?
The only I haven't done is a factory reset, lol.
All this started one night when it was slow charged to 100%. WTF?
TFF the curse of technological Beast!
Guess I'll try recall again.

Right on. Sounds like it's not just my phone. That's a relief. It's puzzling why the phone can't also fast charge with that brick. Perhaps it's simply a bug that Samsung either never noticed, or it isn't a priority to them. It would be nice if we could take advantage of the different settings without having to have two different bricks sitting around.
I think I figured it out. The fast charging setting is for the old classic fast charger. If you connect your phone to that one, you'll see it says it's fast charging. If you don't have fast charging turned on, it'll prompt you to turn it on to use that charger at it's maximum capability. If you use one of the newer Samsung C to C bricks, it's going to do the super fast charging.
I am currently using this Baseus charging plug and get full range of charging options - fast / super fast.
Thought I would try some I have hanging around before buying a Samsung one.

XDA just covered this in their article:
Fast Charging Explained: The slowest to the fastest Fast Charging technologies
Curious about fast charging? Here's everything you need to know about fast wired charging standards and how to pick the best charger!
www.xda-developers.com
Unless a charger has USB-PD PPS they will only FAST Charge @ 18w with fast charge on (super fast on/off wont matter as it will be off). If you are getting super fast charging then you are getting the expected 25w which is totally fine and not bad for battery. You will get super fast with the samsung 25w adapter and maybe the previous series 45w adapter.
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

No huge charging improvement. It most likely will degrade the battery faster.
I use only the Samsung 25w bricks because they are known good and relatively cheap.
Just picked up a 25w brick and cable for $20.
The amount of trouble a defective charging hardware can cause means I won't consider using 3rd party chargers/cables for fast charging.
Fast charging is a nightmare to troubleshoot as I'm learning now... will see if a couple full 100-0% charge cycles get it or not.
It's time consuming and irritating.

Thanks for posting the link to that article. It clears some things up. Charging standards have become rather confusing with all the proprietary standards. This makes me feel more comfortable using the 25w super fast setting on the s21 ultra.
