wireless charging question - Samsung Galaxy Note 9 Accessories

I have long ignored wireless charging, because it's so much slower than wired fast-charging. I keep seeing mentions of the Note wireless charging capability, but I'm still unclear on whether wireless is now as fast? Doubt it, but am I wrong? Would especially love a fast wireless charging solution in the car, that was as fast as the fasted wired option. Does that exist yet? Or do I need to check again in 2-3 years?

Wireless charging is not as fast. Note9 also uses adaptive fast charging 2.0. Fast but not as fast as other standards. I would concern myself about fast charging only when needed. I use wireless charging exclusively at night to slow charge my battery. I think Samsung chose adaptive 2.0 to help with longevity of phone because fast charging does not help with longevity of battery. I am still pressuring companies to unseal the batteries. The environment is more important than being able to take a shower with your phone or not having to worry about dropping it in the toilet because you can't wait five minutes.

The appeal of wireless charging is so you didn't have to reach for a power cord to plug in your phone every time you wanted to charge it. I just upgraded to the Note 9 from my Note 4. When I had a new battery in it, wireless charging only took about 20 minutes longer than the cord. As the battery got older, it did seem to take longer with the wireless charging. For me, if I'm just at home, I use wireless charging. If I'm about to go out in the next 30 minutes for a while and the battery power is kinda low, I plug it in to get a fast full charge. Plugging in the phone all the time is a drag. You are missing out on a cool feature while wasting years waiting for something better. I keep a separate power cord next to my wireless charger. That way I can decide if I just want the phone to get charged using wireless, or if I need a fast quick charge with the cord. You aren't just stuck with wireless charging just because you bought one. A flat wireless charger is just $15 on Amazon. It works just as well as the $60 Duo charger from Samsung, although it does offer fast charging. Not worth that kind of money though. Plus it is big and takes up too much space.

The duo dock is 12W charging. The wired charging is 15W. As for in the car fast wireless docks. I have yet to see one.

I have one. Works well. Got it from Indiegogo, backed a project called the MAGQI X: The Smartest Wireless Car Charger Mount...
It charges faily well but I did find on my Note 8 it was only just holding power as I used GPS...Mind you, that could be caused by the case I had it in, my Note 9 seems to pick up the power pretty quick...

So, can the Note 9 handle the 12W wireless charge or is it limited to 10W? I see the comment above regarding the Duo Dock, but that doesn't necessarily mean that it supports it and I have not been able to find the exact spec on the matter elsewhere to confirm one way or another.

This one is good : [Qualcomm Certified] Tronsmart® Quick Charge 2.0 18W USB Car Charger
Opt among 1 output, 2 output or 3 output. However, please note that only 1 output port supports Qualcomm Quick Charge 2.0. Rest 2 are fast, however, not QC 2.0 Fast.:good:
what is it i need one ?
Check slickdeals. I've been using the $5 one (on sale). It outputs 12v so it charges the phone very fast.

Thanks for that. slick deals is having a promo on this.
However i was wondering s6 edge plus is not qualcomm based, instead exynos.
I was considering this one.
http://www.amazon.com/Aukey-Charger-Adapter-Smallest-Powerful/dp/B00M6QODH2
This is 2.1amp, and is the smallest, it can virtually snap right into your car charger port, without the protruding charger popping out.

Technology is same. High Volt, low Ampere. Any QualComm Certified QUick Charger would be compatible with Samsung's Adaptive Fast Charging. Atleast any branded ones, never go for any unheard brands. Usually Tronsmart, Aukey and Anker are good choices in average budget. Here's a video review I did for Tronsmart Adapter (Quick Charge) with my Edge+ :- https://www.youtube.com/watch?v=DR8W9ozZgAs
Also, please note that I have no affiliation with any of these brands, I just received a product for the review from Tronsmart and I found it really good. And I'm sure Aukey and Anker are equally good.:fingers-crossed:
Also, the Car Charger you are considering isn't fast charging compatible. Although it will not take much time with high Amp output (as specified), but its definitely not a fast charger.
Well, I am using CHOETECH’s Dual USB Car Charger with a dedicated port certified by QUALCOMM’s quick charge 2.0 technology so that I can charge my S6 Edge plus at quick charging rate even on the go. The main specialty of this charger is that it is not only charge the fast charging devices but also Apple devices like iPad Air 2 or iPhone 6 plus at much fast rate as compared to their original charger. You can consider to buy this from Amazon: http://www.amazon.com/dp/B00YX7Y3G8/

Thats very good info. Charging technology is evolving with the phones, and thats a very positive start.
The day is not very far when we might have multi thousand mah of battery juice and charging becomes a weekend job.
Do you mind taking notes while charghing 20% of battery with both the qualcomm fast charge, and the regular 2.1amp charger.
I've already placed an order for the Aukey 4.8A / 24W Dual USB Car Charger mainly because of the size. I'd really want a charger that can **** plush within the car's charging port.

Charging isn't a very quantitative process. First 20% of charging would never be same as next 20% of charging. Usually with fast charger, the first 20% would be amazingly fast while the regular 2.1 amp might take upto 1.5 - 2 times the time. Also, assuming two different devices have same sized battery, with the same charger, one might get 70% charged within 30 min while the other can get 80% charged. However, by the end of 100%, both might take similar time. Thats why, the % readings aren't very consistent or dependable. Its approximation. With 2.1 Amp charger, you won't loose much time, trust me. Also, I don't have the facts, but I have noticed that when I do the fast charging, battery drains out marginally quicker than when I charge through regular 2 Amp charger. Hope that helps.. :fingers-crossed:

Thanks that was good info. I've received my 2.1Amp Aukey charger.
I tried it yst evening while commuting back home from work, which is about 20min drive, and the phone was at at 50%, and it was able to charge about 30% in less than 30 mins. Looks promising. I love the form factor. you cannot evne see the charger plugged into the car port. Best of all, the car port's cover covers the entire charger when not charging, this way i dont even have to remove the charger jack every time i have to charge the car, just pluck out the wires, and snap the cover back to conseal the charger.

With constant gaming and videos watching (after working hours ofcs ), mine doesn't stay beyond a day. I'm very happy with that though. I have seen significant different in battery life when I keep the power saving mode on and it doesn't really impacts my gaming at all even though it says that power saving switches to the 1.5 ghz cores and stays that way...!
It doesn’t matter a lot but yeah the main thing is internal circuit and the premium component used in the manufacturing. All of the chargers integrated with Qualcomm Quick Charge 2.0 chip inside. But the best components used in the manufacturing plays a vital role. I can trust CHOETECH more in this area as they are offering 18 months warranty, which means they are confident about what they produce or deliver to their consumers.

Add Wireless Charging To Your Pixel XL

Hey guys, Rydah805 here with a nice little review on something cool that was sent to me from Chotech; A USB Type-C wireless charging kit. Basically, what it does is awesome by simply adding wireless charging capabilities to devices (such as my Google Pixel XL) that do not support it out of the box. You will obviously need a wireless charging pad for this to have any function. I personally own two, a Samsung branded wireless fast charger and Choetech’s very own wireless fast charger. For this review, I tested using both in which results were the same. Before we begin, I'd like to make it clear that I am in no way associated with Choetech.
How it works is even simpler too. You plug the wireless charging receiver into your USB Type-C charging port, stick the actual wireless charging receiver to the back of your device (sticking not necessary is using a case but do note that it will leave an ever so slight bump with a case.) After plugging it in and having the wireless charging receiver mounted to the back, you're pretty much set. Now when you want to charge your device, you may just dock it onto your wireless charger.
As for wireless charging speed, I wasn’t able to get it to charge “rapidly” as my Google stock charger states, but charging time wasn’t too far off and isn’t noticeable if charging overnight or if just sitting on your desk at work, like me in both of those scenarios.
When it comes to quality of looks and materials, it meets my expectations but then again, what could you really expect? And if you're curious about the specs on this little guy, it is using qi wireless charging technologies with an output of 5v/1a. This is obviously lower than the stock wired charging rates and of course speed but again, if you’re like me, always at your desk or at home, this isn’t too big of a deal. YMMV.
Now for my personal look and opinion on it. I think it’s cool and coming from a Samsung Galaxy S7 Edge and even more recently, the best worst phone ever, the Samsung Galaxy Note 7 (R.I.P.), wireless charging was definitely missed when switching to the LG V20 and now again with the Google Pixel XL. I definitely like having this as an option and thank Choetech for giving me one to review. Personally, I do not use it quite often as I am a freak about having my phone as thin as possible (thin case fans, where you at!?) but if I weren’t into thin cases, this would stay on my device all the time.
To sum this baby up, it’s great. It gets the job done and does what it came to do, add wireless charging to your incapable device. LOL
8/10 (Wish wireless charging speeds were better but it isn’t a killer for me.)
Link to purchase coming soon.
Looks cool. I really miss having wireless charging since I just plop my phone down on my desk or when it's bed time and I don't have to worry about the port wearing out. This is my first USB C device, so I'm curious to see how well it holds up.
Does your wireless charging pad have much heat when it's charging, both in a case, or if you had direct contact between the receiver and charging pad?

Nope, actually stays about the same temperature wise which is nice. 😁
Sent from my Pixel XL
That sounds pretty cool. The reviews I have read on other ones was that the charge speed was much slower. Don't need rapid charge but standard speed would be more than good enough for me. A few reviews I read said that putting one on a wireless charge dead at night it wouldn't even be fully charged over night. I will probably buy one of these as soon as the link goes up Couldn't find it yet on Amazon.

[q] Wireless Charging Vs Wired Charging - Impact on Battery

Hey guys,
I was looking for some clarification on this topic.
So I heard on a youtube video (can't remember which, for the life of me, I just know it was an S8 video) that Wireless Charging has a better impact on battery in the long run.
They had stated that the battery would continue to hold a better charge over time, where as, if you used wired charging, the amount of charge the battery can hold over time would be much less to when you first got it.
Now I do know that battery gets worse over time, however, I have never heard anything about how wireless charging can increase the longitivtiy of the battery.
Maybe someone on here might have more information on this?
I will try to find that youtube video but if this is the case, then I will definitely need to get a wireless charger.
Regards
Unless this youtuber tested 2 phones for a year, charging one with a cable and another with wireless charging i wouldn't listen to what they're saying.

Yeah I agree. A believe a charge cycle is the same regardless of how it is being charged.
Would never think wired charging puts more stress on battery life.
I think though that with wireless charging once the phone is fully charged the pad cuts out so it won't over charge
With a wired connection when the phone is charged its still consistently trying to charge which can end up damage battering the long term

This is also what I have been wondering. If this is true then I may get a nice wireless pad for charging overnight (maybe the new official samsung "convertible" one but its damn expensive). I would have thought that the phone itself knows when a battery is charged and stops drawing the current from the cable though, so it would make no difference either way if that is true (but perhaps its not?).
But I did hear the exact opposite to op, that wireless charging was worse for the batteries, possibly due to the heat generated. But I don't know how true that is.
True
It's better for the battery because it charges it more slowly than a direct wired connection. There is no more heat buildup than using a wired charger, in fact likely less since the charging rate is lower.
As for the other comment that a wired charger doesn't shut off but keeps charging once the battery is full is patently false. The charging circuits whether wired or wireless are quite intelligent and gradually ramp down the charging current as the battery approaches capacity, ultimately delivering just enough current to keep the phone running. In a closed system the energy has to go somewhere and if the charger didn't do this you'd have 18W of power being dissipated as heat and a serious problem on your hands.

For wireless I believe the heat generated is more, it is about the method of delivering the power, not the speed. The induction used to transfer power wirelessly is obviously going to be far less efficient and will generate more heat to get even a slower transfer rate then getting the power straight down a cable (but if someone knows otherwise then feel free to correct me). But then I guess the slower charging rate might also put less stress on the battery which is probably good.
For the wired, what you are basically saying is that leaving a phone plugged in to a wired charger will not harm it since the current will have been reduced in the same way a car battery charger might reduce it to a "maintenance" mode once it is fully charged. So people are believing the old myths that you can overcharge a phone, which would seem to be impossible (although I do wonder why they keep slapping up notifications saying things like "FULLY CHARGED! UNPLUG CABLE!" as if leaving it plugged in would in some way damage it!).
Just saw this which explains the overcharging possibility (or lack of)

The coils themselves don't generate a significant amount of heat, it's the battery itself that causes the phone to get hot. Slower charging means less heat, which is better for your battery so wireless charging will increase your battery life. As the article notes it is also best to keep your phone above 40% charge, partly because fast chargers slow down significantly after 50% to save the battery. That initial burst from 0-50% is done to save you from a dying battery but it takes its toll.
Also note that the S8/S8+ have new battery technology that provides much improved battery life. They're saying 5% loss of capacity after two years compared to 20% for previous generations.
As a bonus not continuously plugging/unplugging a cable from your USB port will make that last longer too. I hardly ever plug my S7 Edge into a physical cable, and I know quite a few people who have killed their USB ports and can no longer charge and or transfer data from them.

Yeah I am torn at the moment between using cable and getting a wireless charger. I like my stuff charged asap but that's partly because i never leave it plugged in overnight and want it charged before bed (which I now know is not a problem anyway) and partly because i want to be able to unplug it to use it if i get a message or email, which isn't an issue with wireless as I can just pick it up and put it back on there after. I assume taking it off the charging pad and putting it back on will not have any detrimental effects to the battery. I am just trying to weigh up the pros and cons of each. All things considered I am leaning towards wireless, particularly if it isn't worse for the battery (although lets face it the difference in degradation between wireless and wired, is going to be so small it's probably not even noticeable after a couple of years by which time I would have a new phone anyway). I wonder if there is a better wireless charger which will be more future proof than the new convertible samsung one (in case I ditch samsung in future) and still give max speed, I would like one that is tilted so I can see the screen though.
My s5 is 3 years old and has only ever been charged by the massive double width "micro USB" cable which takes some force to get in and out of the socket. Still works perfectly though. Never had any usb port of any kind on any device fail, no idea what these other people are doing to kill them!

Having the dock by my bed is very convenient. Just place it on at night and pick it up during the morning. If I need to grab it for anything I can without getting tangled up in wires and it even sits at the right angle so that the always on display becomes my nightstand clock/alarm clock. Once you've gone wireless you won't go back.

I always turn my phone off at night anyway so I don't get disturbed by some spam message or something (I know I can probably set it up to be silent at certain times, but then why leave it on at all, using the battery for nothing). £70 for that Samsung charger though!! I know there are much cheaper ones but I am not sure they will charge at the same rate, the new samsung one charges faster than any previous wireless charger AFAIK and I would want one where the phone can sit up, and most are just flat. Hmmmm although the do have it for £50 on amazon sold by "fonejoy", still steep though.
This one looks good https://www.amazon.co.uk/CHOETECH-W...=UTF8&qid=1492192247&sr=1-9&keywords=choetech but not sure if itll charge at the same speed as the new samsung one and doesnt use a USB-C connector which probably rules it out. May as well just get the samsung one.
I use the US version of this and it works fine. https://www.amazon.co.uk/d/Mobile-P...d=1492192742&sr=1-5&keywords=rav+power+qc+2.0. The Fast Charging Dock comes with a cable so that should be all you need.
And yes, I have my Do Not Disturb settings to suppress notifications 10:30PM to 6:30AM. Wife complained she couldn't sleep with all that noise going on

Thats a wall charger? I'm talking about the charging pad itself. I believe the new Samsung one outputs 15w so is faster than any previous ones which are all 10w I think.

There are only two types of charging dock, standard and fast-charge. None of them output 15W to the phone. The expensive Samsung is just a fancy fast-charge dock so it will charge at the same rate as the Seneo and others that support fast-charge. The Samsung fast-charge adapter only provides a maximum output power of 15W (9V @ 1.67A) so it would require 100% transfer efficiency to charge the phone at that power, and in reality it's only about 65% so at most you'll see 10W versus standard Qi charging at around 7W.
All of the Seneo chargers I have coupled with RavPower or Samsung Fast-Charge adapters charge at the same rate (10W to begin with tapering off to 7W above 50% charge).

Ahh ok, I will have to check out a few seneo pads.
If your using fast charging AKA Adaptive charging it shouldn't matter either way. The Fast charging port on the phone, and the wireless charging should go through the phone and the phone should automatically stop all charging going to the battery. This is the reason why if you were to leave your fast charger on all night whether it be Wireless or wired, you can pick your phone up at 99% or 98% instead of 100%. The phone stopped charging, then when it drops to a certain % it starts to charge up again.
As far as which is actually best for strain, it shouldnt matter because afaik to the battery its the all the same. Wireless charging just has some coils almost that send the charge wirelessly, but it still goes to the same place.
This is what I have read from google, so I am no expert on the subject, but it seemed pretty legit, and makes sense to me, a person with a Tech background. If anyone knows better please be my guest.
I'm going with wireless charging pads at home but a magnetic cable for in the car.
Not found a good car holder that has the wireless pad built in so I will stick with my ibolt for a bit longer

There is no correct answer to this question. Battery life is function of many things -
1. Every battery has specified charge cycle. One full charge from min to max is 1 cycle. Two full charge from mid to max is also 1 cycle. So the more you use your device, charge cycles will come to an end more quickly. For example if you use two similar spec phones; first one you use heavily requiring full cycle charge everyday vs second which you use less and requires full charge every alternate day (or to phrase in other way, first is almost completely discharged by evening, second is half discharged). So the theory goes that second phone battery will last double the time than first.
2. Every battery articles you read, you will find recommendation to charge battery in specified current or usually slow charging. Today's battery technology should be immune to this but I still turn fast charging off. It is likely that not all the batteries are immune.
3. Heat is bad for battery. Some wireless chargers heat up. The TYLT VU that I use get uncomfortably warm when I place phone vertically (possibly coils do not align and multiple of them gets activated). Heat build up is there during fast charging too. If you play CPU intensive games and charge at the same time, phone gets warm. All this heat is working negative to the life span of battery.
4. Lithium ion batteries have less chemical stress when they are not fully charged or fully discharged. If you research you will find articles telling one to keep battery between 40% to 90%. Hence I usually do not charge to 100% and if I do, I watch or play games to bring battery level down. Search for best charge level to store lithium ion batteries, I think it is from 45% to 50%. This I guess keeps batteries at the least chemical stress state. So do your maths if you are type who likes to keep battery at 100% charge at all the times.
As you can see there is no straight answer to this question. Battery life is function of all these factors.
Added: I didn't read full article but you can check this link which speaks about impact of heat and leaving battery to full charge state.

Thanks for everyones input on this!
By the way, not sure if it has been mentioned, but this is a pretty cool read:

So looks like the S8 won't deteriorate as much over time!
I got the OEM samsung convertible fast charging pad but it doesn't come with a wall plug as I read somewhere (I guess thats just us in the UK getting screwed over yet again). The manual says "Use only Samsung-approved chargers that support fast charging (9v/1.67A, 9v/2A, 12v/2.1A).". So I need a wall plug that will be able to provide the fastest charging speeds from it (which I am guessing is one that does 12v/2.1A??). I dont think all the standard plugs with 2.4a sockets are going to do it right? The "30w" RAVpower one that craigdamey linked says it can do 12v/2A but only for QC3.0 (which I obviously wont get since its just being plugged straight into the charging pad), otherwise its 5v/2.4a. Not sure what one to get now. Theres an Anker 24w one but that says 2.4a per port (I know little about electrics and how these things work!).

Anyone else having wireless charger issues?

I have a basic cheap qi charger I used with my last phone, never had an issue. With my Mi 10 Ultra it only charges correctly like 1/10 times when I place it down on the charger. The weird thing is it shows it's charging, the pad and phone get warm which means electricity is flowing somehow, but the phone drops in battery instead of charging... I don't even know what to say or do. Kind of tempted to buy that 55w wireless charger though.
I had a similar issue but found that I had a few stock apps going in the background draining the battery quicker than it could charge (it was a cheap low wattage charger). Force closed the apps and killed a couple of processes and it steadily increased. Not ideal but I took that as a sign of using a cheap wireless charger.
Still on the stock chinese Rom until I get out of unlock jail so if you're on the EU Rom this might not help.
I bought the 55W wireless charger with my phone and it's brilliant.
I tested my previous Samsung 15w wireless charger & Huawei 15w charger with the Ultra and the charging speed was a trickle (according to Accubattery app) and near unusable on the phone so will probably go for the Xiaomi 55w charger from Aliexpress which some sellers seem to be offering the 65w charging brick with.
Will sell the 2 chargers I have whci should pay for the replacement
Does anyone have a source other than aliexpress/baba for the 55w wireless charger? I don't want to wait over a month for it.
Eh... I found other sites where it cost more and took longer to ship. I decided the fastest way to get it was to buy it from the fastest shipping seller on aliexpress and not delay any more
mine seems to have stopped saying fast charging when using my wireless charger, possibly since moving to the EU rom.
Just as proof this phone has something fundamentally wrong with its Qi charging compatibility, the charger only draws 2-3w from the wall when it's not working right. It uses 8+ when it's charging right. That's not the charger. The phone is doing something wrong.
2-3w appears to be what it draws when it's doing the detection algorithm to make sure it's compatible and will accept a charge. It does the same thing on my old s20+ but then goes up in wattage when it's actually charging to 9+.
I am using the 20W wireless car charger together with the 55W wireless charger (with 65watt GAN charger), and both of them works fine and fast. Just to beware that the car wireless charger is quite heavy and may stress your AC vents.
Something has definitely changed since moving to the EU rom. On the CN rom, it would activate the fan in my Huawei charger and say fast charging, now no fan and no fast charging.
Have you added it as a bug on the EU forum. It's ok noting it here but it needs to go on the bugs list to be noticed

Will superfast wired charging kill wireless charging?

When I bought my Samsung Galaxy S22 Ultra, I looked around for wireless chargers. The official Samsung store was out of stock, and so I settled for a 3rd party wireless charger which had good ratings on Amazon.
It charges my S22U fine. I see 'Fast wireless charging' show up on my phone and the phone charges as expected.
Then I bought an iPhone 13 Mini with the official MagSafe charger.
Here are my observations:
1. Wireless charging takes atleast twice the time that is taken by wired charging.
2. Wireless charging generates a lot more heat than wired charging. This is bad for the phone.
3. You can't use your phone for the most part when it is charging wirelessly. And you shouldn't too given the amount of heat that it generates.
While Samsung, Apple, Google do not allow more than 15W wireless charging, some brands allow upto 50W wireless charging. But that also means a lot of heat being generated, which is really bad.
So I made it a point to not keep my phone on the wireless charger for more than an hour to limit the heat generated. I would use wired charging in the morning to fully charge my phone while I'm busy with my morning chores, and then use the wireless charger for topping up the charge in the evening.
And with superfast charging offered by most Chinese brands today, the need for wireless charging diminishes even more. Fully charging a phone under 20 minutes will become the norm in a couple of years. This will also be more convenient than using a wireless charger that had only one thing to offer: convenience.
Do you think superfast wired charging will kill the inefficient, time consuming, heat generating (and component damaging) and less convenient wireless charging technology completely?
Wireless charging is just a convenient gimmick, in my opinion. Wired charging will always be superior to wireless charging for the main reason that direct contact is more efficient than inductive coupling. There is a reason why power transformers use ferrous cores instead of air gaps.
I don't think it will go away, though. People like the idea of placing their phone on a charging surface instead of fumbling for a cable. I personally would prefer the cable simply because I use my phone often, but not everyone uses their device the same way.

That is actually true.

I find myself fumbling more with placing the phone properly on the wireless charger. Wired charging is actually much simpler and no fumbles.
iPhones have the magnets in them to address this issue, but the circular magsafe rings I see on most cases that support magsafe charging makes them look so annoyingly ugly.
I only like wired charging, wired Ethernet, wired POTs, wired alarm system, wired operator switch board !

Why so?
Wireless technology is improving and is definitely more convenient.
But wireless charging has still a long way to go because currently it is very inefficient, time consuming and potentially damaging to the phones.
