Any Difference in Wireless Chargers?

I have a Samsung wireless fast charging pad I bought for my S7. Is there any difference in the charging speed between it and the latest dock style ones?

Nope

Maybe you know. I was told that using non-original wireless charging is bad because they spoil the battery. Is it so?

Generic wireless chargers do not fast charge in my experience. I have tried 3 off of Amazon so far.

I have a Seneo Fast Charger stand and its been great .

As long as the wireless dock is Fast Charge capable and your adapter is QuickCharge 2.0 compliant it should work. I have four Seneo Fast Charge docks that I use with both Samsung and RavPower QC 2.0 adapters and they work great with my S7 Edge. I will test when I get it but I'd assume the S8+ will work the same.
You know if it is working because the phone displays two messages when you dock it.
"Charging wirelessly xx%"
and then after a second or two
"Fast charging wirelessly xx%"

I believe the S8 (like the S7) can accept up to 15w wireless charging (Qi 2.0 spec) but most chargers barely output 10w. Not sure why but I would be looking for a good 15w output charger unless theres a reason not to.

What does "spoil the battery" even mean?

I think the reference is to batteries losing capacity. The older a battery is the less capacity it holds. A battery rated at 3600mAH might only hold 2000mAH after a couple of years of use. High charging current causes a lot of heat buildup in the battery and will shorten (spoil) it's life.
Best way to tell if your battery has lost capacity is to measure charge time. Having it die quickly could mean it's just running too many apps, but charging time (with the phone off) should give an indication of battery capacity. If your battery charges twice as fast as a new one, it's lost half its capacity.

Got it. Sorry, I actually thought they meant that the battery spoils. Like the way some "normal" batteries blow up if left in devices for too long. I was seeing memories of the S7 nightmare.

AFAIK, the only listed change between the Dock style Samsung Fast charger and the Convertible Fast charger is that the new 1 can be changed from dock to pad.
I just picked up 2x Dock styles from amazon for 40 bucks a piece, way better than spending 70 for the convertible style.

Or these?

I was amazed how quickly they showed up too. Took 3 days from order to delivery. I think they purposely put almost 2 weeks delivery time just so that when you get it "early" you're amazed.

Means that the battery holds its charge less. Faster discharges, in general the life of the battery decreases

If you use Qi wireless charger, it has 1.4x faster than traditional wireless charger. Built-in 2 coils offer a wide charging area, which allows you to place your device in either portrait or landscape position. You can also continue using it to read, watch or type while the battery is being replenished.

How will Quick Charge 3.0 affect battery capacity?

QC 2.0 completely wrecked my battery on my S7 due to it always becoming very hot while charging with the option enabled. Still the case with the U11's QC 3.0? Should I leave it off most of the time?

You can't manually turn QC on and off on HTC devices. However, you can use older HTC chargers without QC support.

Only thing I know is the only time I have had problems with an HTC battery is with the HTC One M9. It barely lasted a year but I was able to use the warranty to get the whole phone replaced through my Verizon insurance. I have heard other have problems with the M9 battery as well, haven't had or seen any problems with the HTC 10 battery.

HTC 10 doesn't show any signs of degradation and it got about 10 degrees hotter than the U11 does when it's charging and has half the actual battery life so it was always on the charger. Heat isn't the biggest battery killer, full charge and discharge is. Lithium ion batteries should float between 5 and 90% ideally and you should never leave a fully charged battery on the charger as the trickle charge keeps it at max capacity and wears it out faster. Smartphones are among the few devices that continue to charge the battery after it hits 100% - I use high drain lithium ion batteries in my vape mods and the external charger and internal balance charger on my DNA 250 will actually stop charging at 100% and when I wake up will be around 98-99% which means the stress on the batteries stopped at the correct 4.2v and naturally dropped.
I wouldn't worry about the heat as much as the other factors.

The major improvement comes from QC3.0 is improved heat, the charging speed between QC2.0 and QC3.0 is small to none.
I've only got a QC2.0 powerbank can't test QC3.0 but since I never use the U11 when it is in QC2.0 charging mode, the hot is low to me. If you will run the phone with charging therefore QC3.0 is a must.

the Quick charging kills the battery
to have the longest life span it is best to use a charger with 1 ma output such as iphone chargers
charge it quickly only when you really need the battery I did that with my 2 year old note 5
and the degradation after two years is some way between 30 and 20 % which is acceptable after two years

Actually quick charging doesn't, over charging does. Charging the battery and internal temperature gets too high as well. It is even said these batteries run better and last longer when not fully charged.

quick charge 4.0

They added qc4, but it's more like qc3 with just 18w(9v 2A). I hope a kernel mod will allow the phone to get 27w which will charge the phone completely in approx 1h 30m to 1h 40m rather than 2h 15m with the 18w charger.
Whatcha think nerds?

I think that's a bad idea as they will have specified a battery suitable for 18W charging ...
Battery should last for ages, anyway. It's 5000mAh, very close to pure AOSP, and the display is by no means large.
If you endlessly play with the camera motor, it might drain a bit faster, but otherwise, I suspect this will have the best battery life of any phone in the small flagship class.

I'm fine with QC3.0, since I've used that a lot.
But if it does come with QC4.0 then I couldn't be more happier.
With the battery capacity it has, I don't think I need to charge it all the time so QC3.0 is something extra for me.

The sustained speeds should be higher due to the battery size but I wouldn't personally want to risk modding the charging speed. Sounds like they made the insulation layers pretty small to get the capacity at the expense of charging rate.
My main concern is how well it sustains the speed and the temperatures (QC4 should be decent in that regard) because any maximum speed will drop off a cliff when it gets to 70-80% anyway.

Does it have 4.0 or 4.0+? I've seen some spec sheets saying it has 4.0+

It's really difficult to even find data on what the difference of those two are in real world scenarios. If I'm not mistaken the + version requires two PMICs (whereas it sounds like it was optional before) and I think the Zenfone might just have one. Asus themselves advertise 4 without the plus. If you ask me, Qualcomm should just have called it 5.0 to avoid the confusion especially because Qualcomm's own marketing material is very vague on this.

I'd be surprised if the battery didn't get dangerously hot if it's done.
The separator wall of cathode and anode on a battery that can handle faster quick charging would need to be thicker.
Asus chose 5000mAh with a smaller separator to keep size down. In the same size, ASUS could have chosen, like many others have, to have gone with a ~4000mAh battery with a thicker wall to support 30W+ fast charging.
It comes down to trade-offs based on physics. I'm always game for experiments though

Did a very little test. on org charger and cable
Battery on 65% did give 7,5 Volts and 1,65-1,70 Amps

Hello, today, I bought this phone and I plugged it into charger for the first time. However, in my opinion, the phone warms up relatively high compared to my previos samsung S8+. Have you got any experience whit this? Maybe I am too much perceptive and it's normal. And maybe it is the difference between Quick Charge 2.0 (s8+) vs Quick Charge 4.0 (asus)

Mine warms up "as expected" I would say.. nothing surprising at least. Its going to be warmer or less warm depending on where in the charge cycle it is as well

27 w charge
Can we get faster charge while we use 27W adapter? Or will it break the device?

The difference between quick charge 4.0 vs 4+ is that 4+ is compatible with USB PD (power delivery) which is the fastest charging standard, its what i think OnePlus and Samsung use for their tech. 4.0+ was revealed in 2017 a year after 4.0. It's lame but unfortunately Asus's zenfone 6 current batches do not support 4+ (however 4+ charging is still backwards compatible with 4, 3, and 2.0, that's why when @MishaalRahman tried their QC4+ 27W charger it didn't charge any faster, it just downgrades to 4.0 charging speed)
there's a chance a refresh of Asus's zenfone 6 may happen with 4+ release. Doubt it..but who knows
4.0 is still supposed to charge faster than 3.0 but I personally don't really see that increase in charge speed. Could be because of the size of the battery but either way I'm still happy with it because the large battery just means less charging (for me personally) since I just mostly do google searches and text, and once in a while use snapchat/ig. Its the perfect phone for me, I bought it yesterday to replace my Pixel XL (gen 1).

How's your battery capacity holding up after some use with the 65w charging?

Looking at buying this phone but I'd like to know how the battery life holds up over time with the fast charging. What kind of screen off time do you get after 6 months or a year of using the phone?

I've had it for a year and I have charged it with a slow 1 Amp charger every night. I only use the 65w charger maybe once a month. I haven't had any issues.

I've had the phone for almost a year and I charge it with the 65w charger every day. No issues, battery lasts for as long as it did when it was new.

@baxtex
Yeah I just got my 8T today. I did more research and found out they use multiple temperature sensors that will trigger the device to charge slower if it's overheating. They also use 2 batteries in the phone to prevent this heat from happening under normal charging conditions. If it was in the sun or in a very warm room or something I'm pretty sure it would throttle itself based on some of the reviews I found on it. You might have to have adaptive charging on for this but I would assume it's just more aggressive than the regular protections. Pretty sure you could explode your battery with 65w charging in direct sunlight on a hot day. Anyways I think 1A charging is overkill for protecting it. 1A is also not actually not a measurement of current unless you have the volts also. If it's 5V which I think all usb is but I haven't checked since usb-c came out that would be 5 watts. I guess if you leave it on that overnight it doesn't matter though not like it'll hurt anything.

General Well. This is a bit disappointing

S22 Ultra 45W vs S22 Ultra 25W vs S21 Ultra 25W charging test

wouldve expected it to charge much faster, especially when you consider the smaller battery.

Totally expected, 45W works just at lower temperatures and under 50% charge as it was back in the Note 10+ days. It's useful only when you are topping up on the go, for 0-100% it's almost the same

Well it is improved, it was downgraded 2 years ago to be fair and now is back to that state. It charges faster from 0% to 50% which is exactly how it used to work before. If you expected something different your expectations were wrong, don't know what to say. Even devices with very fast charge charge faster for the first half then slow down considerably. Samsung has always had a more conservative approach on charging after the Note 7 debacle, that's why I expected it to be managed like it was before.

I've traded my Oneplus 7 pro. A 3 year old phone and It still charges much faster than S22 Ultra. Considering to I'm paying for a flagship phone which is over £1000 and it's charging technology called "Super fast" charging. Yeah I'm a bit disappointed.

The N10+ with the 25w brick will fast charge from 5-70% at the rate of 2%@min on its 4300mAh battery. Between 70-82% it may ramp down slightly, at 90% fast charging disengages.
This is dependent on battery start charging temperature, if too low or high fast charging will not engage, and battery condition. A 20% charge in 10 minutes isn't bad...
Fast charging is limited by heat buildup in the battery caused by internal resistance. The Li cell charging process is actually an endothermic reaction but is outweighed by the internal resistance generated heat.

I can see it being an issue for those that prioritize fast charging over battery longevity. I charge my device overnight and use a Chargie to regulate the charge to a maximum of 80% and limited to 8 watts. I'm not a power user and this method may not work for everyone.

Looks like they're using an older 45 watter. The new ones are the real 45 watts.

I doubt it. QC boosts the charge wattage by increasing the voltage; more volts less amps means less parasitic waste heat.
What's left to improve on the charging protocol side? They to improve the battery itself now for any meaningful performance improvements.
These manufacturers push the hype, the reviewers do too, then long after the release the truth finally comes out.
If you can wait a few months for the dust to settle you'll get a better idea of what to expect.

There is a new 45w charger, model EP-T4510XBEGGB. This one seems to work fine and not overheat.

Curious as to what your thoughts are regarding the Chargie since Samsung has now added the same charge up to 80% feature in Android 12 under device care. Is it now redundant?
