Is there a way to tell whether you're charging with a Quick Charge 2.0 compatible adapter, vs a standard 2.0A fast charger? Maybe I'm missing something, but the Nexus 6 shows "Charging (AC)" either way.
I know that QC 2.0 requires that the data pins of the cable be intact, and if you plug in a charge-only cable it falls back to QC 1.0 (standard 5V, 2A charger). I'm looking to buy a couple QC 2.0 adapters, and it would be nice to be able to quickly tell if I got my money's worth WITHOUT having to drain my phone and time how long it takes to charge.
I noticed this too. My wife's Note 4 shows a message indicating that its charging via fast charger (aka quickcharge 2.0).
For our phone, I would suggest just plugging it into a known working quickcharge 2.0 charger, like the one that came with the phone. Wait 1 min until it shows the time until full. Then switch to your new charger, wait a min, and compare the time remaining until full. If they are close to the same, then your good to go. At least this would save you having to fully discharge and time the recharge...
The easy way is to use the charger that came with the phone

You'd think that, but accidentally plug the wrong cable into that charger, and you'll THINK it's quick-charging, but if that cable happens to be a charge-only cable, it will be locked to the 5V setting, which with the Moto charger, is at 1.6A. Besides, for some reason, the charger that came with my phone worn't fit in the little round charging hole in my car, so I'm looking to buy a QC 2.0 car charger. The point of my OP was that anyone can slap the words "Quick Charge" on their Amazon product page (especially since any 2A charger is technically a "Quick Charge 1.0" cable -- even if the ad says 2.0, well, that's just a typo -- should have said 1.0... oops!), and I'm looking for a way to quickly test the product I receive.
@TheSopranos16, Good suggestion about waiting for the "...until fully charged" message pops up. I'll have to test that to see if it really does show a different time that quickly with a QC 2.0 adapter. Still, it's something that the Note 4 can see, so I'm thinking it's something that an App should be able to see. I briefly looked, but didn't find one. I was kind of hoping someone else had.

Well i used my N5 cable that came with the charger and didn't even notice the difference, changed back to the moto one because i don't like the glossy look on the LG one.
By any chance you tried using your cable in your car?? Did it charged?? I tried to use mine in my car and didn't work, I got a 2014 corolla maybe it's because of the small battery in the car, I really dunno. It's weird.
Yes I too would like to know what charges and cords work correctly...

UPDATE: Okay, this worked... sort of. Well, it definitely worked, but it wasn't quite so simple. My phone was at about 71% charge, and I put it on the Moto Turbo Charger. A minute later, it said it had about 25 minutes remaining for a full charge. I removed it, and placed it on my Nexus 7 charger (which, incidentally, is only a 1.2A charger, but it proved the point). It took over 5 minutes to show the "charge complete in..." message, in which it indicated it would take over two hours. I guess, you could consider the extended wait time a sign, but something NOT happening is always a really bad way to prove something. Still, once it DID show, 25m vs 2h is definitely a good measure.
The weird thing is... it took about 5 minutes to show that message on the 1.2A charger, during which, the charge increased from 71% to 74%. Assuming a similar 3% increase every 5 minutes, it should reach its full charge in about 45 minutes, not the two hours it stated. Since this was only a 1.2A charger, a 2A charger could do it in almost half that time, or about the 25 minutes that was initially reported. Still, I was at 71%, and at that level, the Turbo Charger may not shift into 9V or 12V modes, so I guess that seemed about right.
I'd still like to see an app that could tell me instantly or, at least, within a few seconds, but this is definitely an alternative. Although, you still really need to test it while the battery is pretty low, but at least it stops the necessity to time a full charge.

You could monitor the charger output with a USB voltage and current meter. For regular charging the adapter output will stay at ~5 V. For Quick Charge 2.0 the adapter output voltage level will go to ~9 V. Just make sure that the USB power meter supports at least up to 9 V (better 13 V) and 2 A. It also needs to have the data lines. Here's one that would work (supports up to 10 V and up to 3 A): http://goo.gl/3OoD3D

Op, just look at the charger specs, by law the wallwart should have a power rating blurb printed on it. Quick charge 2.0 will have variable voltage as well as amperage. 1.0 will only crank the amperage, but not the voltage

Alas, car chargers... not so much.
i use and watch the current widget. the nexus 6 default charger has nearly 2450mV coming in at a certain point of its charging cycle! no other charger will do that for you, i dont think.

the current widget https://play.google.com/store/apps/details?id=com.manor.currentwidget
op brings up a very good point that i didnt realize before. on my note 4, when you plug in the nexus 6 moto turbo charger or any other quick charge 2.0 charger a window pops up explaining adaptive fast charging. you can dismiss it and make it never show up again. you also get an "adaptive fast charger connected" notification in the notification bar. these are very good things. on nexus 6? nothing...

Are there any quick charge 2.0 car chargers? I'd thing you simply hit the power ceiling of the cigarette lighter before getting close.

Actually, most vehicle power outlets have a 10A or 20A fuse (cigarette lighters tend to be on the lower end, while power outlets tend to be on the upper end), and operate at 12V. Even at the lower 10A range, that's 120W of power. Traditional USB Car adapters step that down to 5V at up to 2A, or about 10W of power. The QC. 2.0 standard allows for 3A at 5V, 9V, or 12V, for a maximum of 15W, 27W, or 36W respectively. That's well below what your car can handle. Not to mention that none of the existing adapters even come close to that amperage. Most that I've seen only run at 5V or 9V, at 1.67A. That only 15W at 9V.
So... to answer your question. Yes, QC 2.0 vehicle adapters exist (check out Amazon), and no, they won't even come close to hitting the power ceiling of your car's cigarette lighter / power outlet.
Ooh! I like that Verizon car adapter. That LED at the connector would really come in handy! Thanks, @indianajonze!

You can also use an AC meter such as Kill a Watt
http://www.p3international.com/products/p4400.html
Which might be more useful to have around the house. You should see the charger drawing about 5W for standard 1A USB charger, 10W for 2A and up to 14-15W for turbo. The battery widgets others have mentioned work great too.
Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.
There isn't a need to switch to other kernels.

@zephiK You misunderstood my question. The problem I'm looking to solve is the slow charge rate from the chargers in the original post.
To add to that. My macbook also charged my old galaxy phone @ 2amps but with my n6 only does 500mA.
Nothing wrong with the turbo charger

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.
@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand
Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.
Thanks! I guess I'll have to replace the chargers/battery

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.
I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify. The person I quoted below explained it a little better than I did.

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people
Which charger to use? (no quickcharge)
I bought a Samsung charger for my upcoming Nexus 6, i don't want to use the quick charger that comes with the phone. I am starting to suspect that this one is also a quick charger, can anyone look at the attached pictures and tell me? Also if it isn't a quick charger i would like to use it for the long run so my second question is would my battery be affected because of what says on the back of the box that i highlighted? In the highlight are also the specs of the charger, can someone clear this up for me?
EDIT: I cannot post pictures on the forum just yet, so here are the specs
10W Samsung travel adapter, Input 100-240VAC 50-60Hz, Output 5.0VDC 2A
Use only with compatible Samsung devices

I want to use the phone for a couple of years and don't want to shorten the battery life and also have the risk of inflating battery and everything that comes with it. What kind of charger should i buy to charge it in some "normal" time? The salesman in Samsung store told me this one charges Note 4, Galaxy S5 - which is why i bought it - the S5 doesn't have the quickcharge tech so i instantly thought it was an ordinary charger. On the other hand, my Galaxy Nexus official charger is rated for 1.0 A which surely isn't strong enough to charge the 6 properly so i am confused with what kind of a charger and with what ratings should i get? Thank you in advance.

2amps isn't going to shorten the life below 2 years. Higher amps only shorten life if they are above battery tolerances, which 2 amps is not.
Anyway, you'll want a 1 or 1.2 amp charger for slow charging

If I were you, I would use the charger that comes with the Nexus 6. Which is tested by Motorola to work properly. I've had my Nexus 6 since December 2014 and no problems. I charge through my laptop will at work though.

He wants slow charging. So charging through laptop / pc will be fine.
Charge cspacity of usb ports is 500 mA (900 mA for USB 3.0), that's good for slow charging.
Also 1-dollar charger from eBay will be fine.

Nope. So the only thing that will change is his phone will take longer to charge.
That said for me, turbo charge stopped working and I'm very annoyed.
Google have first sent me a new charger which still hasn't arrived. Though I think the issue is the phone. But I wanted to avoid a refurb as long as possible. Can't live without turbo charge now.
I have this charger, http://www.walmart.com/ip/Belkin-F8J031TT04-BLK-Micro-Wall-car-Chrg-Kit-2.1a-10w-W-4ft/40457559, but i got just the charger for $20. It most definitely doesnt turbo charge, it takes atleast 2 hours, so id say its a "normal" charge for this phone and i think its better than the turbo charger, because it doesnt get hot and its still decently fast

The turbo output is only supplied on turbo enabled devices. So there is something wrong with switching to turbo modes 9 V and/or 12 V
I am curious what is the cause of this issue.
Did you try an 'charge app' like Ultra Fast Charger.?

I think its a usb port issue myself.
I don't know what a charge app is. I am monitoring my input though. I know the issue is not software as it just stopped working one day last weekend with no software changes.
Actually,.could even be the battery as.my wireless charger is very slow now too.

There are some apps in the play store claiming to boost the battery charge.
When wireless charging is also slow, than it could be indeed the battery.
Maybe a complete discharging ?
BTW
Turbo mode is only active when the battery is less than 75% charged.

I don't believe they can but I'm not.going.to try anyway.
You should use a 5 Volt 2 Amp charger, those chargers are the one's that most phones use. Most new phones are using Qualcomm's Quick Charge 2.0, which you should use but if you are not comftorable then the 5 Volt 2 Amp will work good.
Errr, QuickCharge will in fact degrade a battery faster, it's still used because most phones only have a 2 year lifespan.
A non QuickCharger will also make it run less hot while charging and also be less likely to cause cell expansion. Not sure why there's so many people denying this.

Please don't tell him that it won't degrade his battery when it definitely will. It's basic chemistry.
To OP:
Any regular non Quick USB charger of reputable make will do fine. I use an older HTC charger. Don't get a super cheap offbrand one as it probably has fluctuating voltage which will also damage your battery.

Actually you've misread (or not read fully). No one disputes the science. That article isn't accurate. All it says is "too quickly" and if you read what I have said, is that the turbo charger is within acceptable tolerances. I.E. It is not "too quickly"

I think you're not understanding the basic chemistry. More heat = more degradation of the Li-ion battery, regardless of tolerances. A lower power charge will always degrade the battery slower. This isn't about tolerances.
Hi
I have the P9000 on the way and I am looking forward to it arriving. One question I have is what are my options for a fast charger? I am in the UK so require a three pin plug and don't want to have to use an EU to UK adapter. Am I able to use one of the many fast chargers on Amazon that say they work for Qualcomm's Quick Charge but do not mention PE+?
Thanks
i use the supplied cable with a three pin usb to UK wall adapter that we all use with older phones.
never timed it but it charges within an hour or so, its much faster than any other device i have on the old charge system.
no need to buy the 2 pin fast charge device their trying to flog on their site.

I just thought some sort of higher amp charger would be needed to power the quick charging, but I shall wait until I have the phone then see where I can go from there.

Yeah I thought the same too. Good luck with phone, I think you'll be happy with it. For price its a bargain
DON'T buy the Elephone branded wireless pad though, mine is rubbish (for normal charging that is, as I know its not a fast charger) its connects / disconnects all the time. Yet my son has a cheap wireless pad he got of eBay and its rock solid, lesson learnt I guess
I live in the US and I just use an iPad 12v charger. Takes around 45-60 mins to fully charge from 10%.
I use the one that came with my Google Pixel C

Yes, agreed, my phone charges quickly, whether using the fast or a standard charger!
I'm using a Lumsing 4-port charger (the "old" model without QC 2.0; 2.1A max per USB port) and it charges my phone really fast, I'd say about 60% in one hour. So I dismissed my plans about buying the official quick charger

what is the output amp rating on your charger?
I just bought an Aukey QC3.0 charger and it does like 80%/h
I bought a meizo PE+ charger and it does the job. Around a hour form 0 to 100%
Are these chargers that you use safe / fully compatible
I'm using tronsmart quick charged with volt IQ, is a very good option

How quick?
Everyone saying that the 'output amp rating' on 5V only output chargers is the way to determine if you're fast-charging your Elephone P9000 is unfortunately incorrect. A phone with PE+ uses load modulation to signal to a compatible charger that it should adjust its output VOLTAGE. There's a datasheet available somewhere that describes the protocol, but basically one set of current pulses (can be observed on an oscilloscope) means turn up the voltage, another set means turn down the voltage.
I managed to observe this behaviour, and simulate a compatible charger with a bench supply. When I saw the current pulses indicating a 'please increase voltage' signal, I wound up the volts on the supply from 5 to 12 volts, and the phone would draw up to 1A at 12V. If I left the supply at 5V, I would only see a maximum draw of around 1.7-1.8 A.
All this means is that compatible chargers are running at up to 12 Watts, whereas "high output current" chargers which only put out 5 V will only charge the phone at 9 Watts. Also, this is not compatible with quallcomm's quick charging system, which actually uses the USB data lines to request the increase in voltage.
Also, in general, cables are important. Phones will monitor their input voltage, and if they see it drop below some threshold, will reduce their charge current to match. If your charger doesn't have the current capacity to shove out to your phone, then the supply voltage will droop there and the phone will reduce the load. Similarly, if there is too much voltage drop down the cable (V=IR, R is the cable resistance, I is the current draw, V is the voltage drop) then the charging current will also be automatically reduced.
Also, strangely, my elephone p9000 recently stopped doing the PE+ thing! Now, there are no current pulses, and it only draws at 5V. *confused
I totally agree with the explanation of robot-army.
The Pump Express + charging technique is more than a simple current flow grossing.
This subject have been analyzed on another phone using the first mediatek Pump Express design used in the Zopo Speed 7:
http://forum.xda-developers.com/speed-7-plus/general/mediatek-pump-express-plus-zopo-7-t3336430
In that thread, you'll find the document that explain clearly the signal pattern awaited by Pump Express chargers to give their full potential. Without this management, they're just normal chargers and could be used in any other phone or device using USB standard to be supplied.
@robot-army: your problem regarding Pump Express management is known and it seems that since update 20160608, the kernel doesn't include this function anymore...
I saw that you shared your issue in the official Elephone forum on the following thread:
http://bbs.elephone.hk/forum.php?mod=viewthread&tid=11411&extra=page=1&mobile=2
I don't know if the kernel source used by Deepflex will let him put back this option ON in his CM13 Rom as it's an important feature of this phone and it seems that the Elephone Software checking team is not very serious about this point...
The lack of control of an highly advertised feature is a remarkable flaw, and even the last 20160715 update available doesn't correct this important point!
Please Elephone team, have some respect with your customer. The P9000 has a very good hardware basis, but you're making people changing their opinion because the software basis is not handled properly.

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.
