Ive seen threads for almost all the wireless chargers except this one, so ive decided to create one to unite all the information.
Ive just ordered it on amazon for 50€.
What is your experience with it guys? Cant wait to recieve it.

I have one here and it works fine, charges my phone with no problem and temperatures never go above 36c. The only two issues I have is firstly the Nexus 4 slides around on this thing like there is a layer of Teflon between the phone and charger. I heartily recommend LEAVING the protective film that the Maxell comes with ON the charger that stops the phone slipping.
Secondly forget about using daydream with the charger, in my experience daydream uses up too much power to be useful with wireless charging. The battery charges at snail pace and the phone heats up to over 45c with daydream enabled. I like the Maxell and I like wireless charging my first choice would be the Nexus Orb if it was available, but the Maxell does a good a job as any.
Thanks for the advice. Will keep maxell plastic on. Wish they could deliver it faster. Will take a month

Just got one of these from eBay for £42. Seems to charge fine with the N4 the S line TPC case on.
My only, albeit minor, issue with it is the bright blue LED which illuminates while charging. This is easily resolved by making sure the N4 covers it or stick a bit of dark tape on top.

I just picked a Maxell Air Voltage charger up from Ebay here in the UK, it is a very nice bit of kit I must say and works great, the only downside is that the charging range isnt too good, I was expecting at least 6mm so that I could charge it whilst it was in my flip case, it wont charge through the flip case and it wont charge through any case that is metal or has a foil liner this of course is fairly obvious.
i am sure some of the thinner plastic half cases and gel cases it will be fine, I think that the Nillkin Fashion Shape Flip Leather Case is also OK with it so I will pick one of those up with it.
I tested the effective range with UK 2 x 1p pieces stacked on top of each other which is 3.0 mm thick in total, so if your case it over 3mm thick then it wont work without taking the phone out of the case, something to think about if you are going to get this charger.
I wouldnt hang on to get the orb charger, thats a long way off IMHO, the Maxell air voltage is a great unit, is cheap and will work with other QI devices, well worth getting it.
Sounds good so far. I've ordered mine off Amazon after hesitating because of the price.. Taking ages to arrive during this holiday season. Looking forward to it.
Had mine for around 2 weeks now, works perfectly with my tpu case on.
Did originally have daydream turned on and it was a little slow but now its off it charges great.
Well worth the money. If they were a little cheaper i'd buy another!
hi,
does it use 110 or 220 voltage?
I also have the Maxell charger of Ebay and it charges through the Nillkin hard case with no issues at all which was a deal breaker for me if it couldn't.
I agree with the comment to leave Daydream off as it seems to charge the phone better..

Cheers mate, I was a bit worried about charging through my S-Line case. I've just ordered one from play. I have a desktop stand, but sometimes the connection doesn't fit in properly.
Got my nillkin case for my n4 which is superb and can confirm the Maxwell does charge through it as the other poster mentioned so it isn't a one off, if the case was a little thicker it won't do it though so be warned

Mine is getting stuck at 89%. Then it goes in to a state of limbo where it disconnects, uses up a bit of charge, reconnects, gets back to 89% disconnects, etc etc.
Anyone else? Defective unit?
Also, has anyone else suffered severe battery life deterioration after using this? It may well just be coincidence but about 3 days after first using it my battery life has fallen off a cliff. The Android Kernal OS is suddenly showing up at over 30% usage on the stock battery data page, whereas before it was under 10%.
Working fine with mine no problems. But I find when it charges to 100% it waits until it drops to 95% before recharging again. This is fine as I understand that qi charging doesn't allow for trickle charging, so it's either full power or no power. I wouldn't say it degrades the battery life but rather it screws up the battery stats. To fix this I just plug the usb charger once a week or so.
I think the capacity reading gets messed a bit as due to the on/off charging after reaching full charge, since unlike trickle charging where the battery's voltage is kept constant, the voltage is always raising or falling. Depending on when you take your phone away with you in relation to its current charge state you might get a slightly lower capacity for that particular charge.

What im going to do to solve this is buy a electricity temporizator and set it to 3 h so it stops once those hours are done. I always charge mobile at the same hour.

Trickle charging is horrible for lithium ion/poly batteries. Unplug from AC charger as soon as you can. LiOn batteries don't like to be at full peak 4.2v for long. It's actually better that many of these Qi chargers are only charging to 89 or 95% of capacity by the wireless charges. It's better for the long life of the battery. Charge them often too. Don't let it go down to 10% or 5%. Put them on the charger when your phone is down to 50% and take them off the charger when they get to 90%. It's easy to do with a wireless charger.

I'm actually aware that constant trickle charging at full charge isn't ideal for long term health of the battery. Which is why I mentioned I only plug the wired usb charger once a week. I only plug it in for about 30 mins so the voltage stabilises as to help the phone more accurately display its charge % state better. Obviously it's all subjective as I've yet to actually perform any tests to see if it's ture or not.
On the subject of long term battery health, trickle charging on wired may not be ideal, but nor is wireless charging due to heat it produces. During wireless charging, according to my battery stats widget the phone reaches 39°C, while wired usb it never goes above 22°C (room temp. basically). The good thing about wireless charging is the heat drops back down when the battery is full and the qi charger is no longer sending any current. But when the charge drops back down to 95 % it restarts charging again, and the heat returns.
So, which is more harmful to the battery, heat or constant trickle charging? In either cases it's still a good practice to remove the phone from the charger (both wired or wireless) once it's reached full charge.

I want a charging dock for my S4 that will feed the phone the full amount of power that it can take, for quickest charging. I believe the stock charger that came with it supplies 2 amps.
I also would like said charger to have a slot for charging a spare battery at the same time.
All the charging docks I've found so far only claim to supply 1 amp to the phone, or less. Except one dock I found that did say it outputs 1.6 amps.
Does anybody know of a charging dock that will supply the full 2 amps? How about one that also has a slot for charging a spare battery?
Thanks.

Would you like it to serve you eggs and ham as well?
Damn.. you are really asking for so much and not nearly searching for it yourself enough if that makes sense.
There are charging docks that have a battery charger slot as well. They have a microusb port for power input. You can use a 2A charger with it and I believe it should be charging the phone at 2A but only when you're not charging the spare battery. I do not have the link as I saw it while randomly browsing through S4 docks on eBay. It's easy enough to find.
No, thanks. If it could cook my eggs and ham, it would be too bulky. LOL!
I looked through roughly 150 listing on eBay. I saw a whole bunch that said 1A output. And a few that were 700 mA, and at least one that was 500 mA. And exactly one model, available from a few different vendors, that said 1.6A output.
I did not see any that said 2A output. Just because the wall wart can supply as much as 2 amps, doesn't mean the charger will actually output that much to the phone.

My advice, is you should risk it.
If you're looking a product with such precise specs, I'm afraid you're not going to find it.
I messaged several different ebay sellers last night to ask if their charger is really only 1A and if they'll be having a 2A model. So far, I've gotten responses from 3 or 4. All of them have said sorry, we only have 1A. Please note, it will charge more slowly.
Update info. This may be old news to many, but here it is.
I had an online chat with a Supervisor at Seidio this morning. Their website has 2 charging docks for the S4 and neither lists charging output.
They told me that the dock will output whatever the wall adapter supplies. The charging dock is a passthrough. So, if I use the stock OEM charger with the Seidio dock, my phone will (allegedly) still receive 2A of charging current.
This may have been intuitively obvious to some, but it wasn't to me.
So, my quest is now much easier. Apparently, the docks I looked at on eBay that say 1A charging output must say so because the supplied wall adapter only provides 1A. And ones that say that but don't include the AC adapter are just making an assumption about that AC adapter you'll use.
BUT, though the phone charging port may be a passthrough, the slot for charging a second battery (on docks that offer that) would have the charging logic/circuitry built into the dock, so that could still be limited to 1A or less. At least, that's what I think. Could be wrong.
Regardless, i ordered a cheap dual charging dock off eBay that should be here by Friday. Using Galaxy Charging Current (a free app in the Play store), my phone shows 1900 mA charging current when plugged into the OEM charger directly. After I get the dock I ordered, I'll test that and report back.
If the dock will charge the phone at full speed, I can live with the spare battery being charged more slowly.

It's NOT a dock but a charger and it does come with an OEM spare battery. It charges a battery from 0 to 100% in about 4 hours, which is faster than your phone would deplete a battery, even when gaming. Paid $47, no shipping from Amazon
I see the price have changed a bit meanwhile but it's worth it if they still don't charge any shipping. Ships directly from Korea (made in Korea - both, charger and battery)

Hope it works out. The dock i ordered from seidio for my evo 3d did not charge at full power with the supplied adapter. I used a diff cable and power source and the results were better, but still not very good. Most nights I simply removed the cable and plugged the phone directly to it bypassing the dock, kind of defeated the purpose. I hope to find one that keeps the S4 charged.
Well, I received my eBay dock today, 2 days early. It is this one:
http://www.ebay.com/itm/111066155507?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
And when I plug it in and put the phone in it, I get a message that the connected charger is not compatible with this phone. And the phone shows a red X over the battery icon in the notification bar, and doesn't charge at all.
I tried it using the OEM charger and cable, the cable that came with the dock, and I also tried both cables using my OEM charger that came with my Note 10.1 tablet.
Exactly one time, when I put the phone into the dock, it didn't display a message and Galaxy Charging Current (app in Play) showed that it was charging at 1900 mA. But, several times before, and every time after that, it just displayed the message and wouldn't charge at all.

I've seen that and that's a big "no way". My normal deal is, if I run out of battery, it's because I'm out and about. Traveling on a plane. Riding my motorcycle. Whatever. Situations where I don't have the option to plug in. So, I swap batteries on the go and the charge when I get to where I'm going.
This charger on Amazon would require me to carry it, plus my phone charger, plus an additional phone charger to run the separate battery charger. If I were just going to share my phone charger between the phone and the separate charger, I would rather just have the phone on the charger and, when it's fully charged, swap batteries, to charge the next one - not swap the charger cable over to the separate battery charger.
if I were going to go the route of a separate battery charger, I would spend $7 or so on eBay on one of the ones that has a flip-out plug built in and plugs right into the wall. That is the kind I have been using for a while to charge my Rezound batteries when traveling.
The biggest problem with those is that they charge the battery at something like 350mA. Ridiculously slow!

...buddy, that's EXACTLY what this is. It simply gives you the option of charging another OEM battery (in the charger NOT in the phone) BEFORE you go out and about and then swap them as you need.
NO, it's NOT charging as slow as you suggest. They use a technology called direct charge which means that it draws as much (or as little) as your wall plug allows it. In other words if you plug it in the PC USB, then yes, you'll have to wait until you grow a nice thick beard, but if you plug it in your original 2A charger, it'll charge the battery from 0-100% in about 4 hours or less.

Absolutely NOT true:
1. You ONLY need to carry the charger if you plan on recharging the depleted battery BEFORE doing another swap - that's at least 12-15 hours on EXTENSIVELY using BOTH batteries - that's 12-15 hours screen on!!!
2. ONE phone charger can be used on either/or - you'll never have to charge them both in the same time (that's the idea with swapping the batteries, right?)

Up to you buddy, but usually you get what you pay for. The one I suggested comes with an OEM battery. I always suggest using this method over any battery pack as an OEM battery will ALWAYS give you just as much "juice" (this translates into running time) as the...yeah, you guessed it, the Original Equipment Manufacturer's battery. Although the battery packs manufacturers, they all claim huge capacities and running times, this mostly never holds true to the advertised specifications. It's called marketing

I don't think you're getting me. The point is, I get to the end of the day and I need to charge my phone AND the battery I used up. In order to charge both at the same time, using this Samsung separate battery case/charger, I would have to have 2 actual chargers. One to attach to my phone, to charge that battery, and one to attach to the separate case/charger.
Get it now?
More detailed:
- I start the day with 2 fully charged batteries. One is in the phone.
- I ride my motorcycle all day, streaming music via Bluetooth to my helmet, and talking on the phone while I'm riding.
- Before I'm done riding for the day, my battery dies, so I swap it.
- I continue riding, etc.
- I get where I'm going and I'm ready to go to bed.
- I now have a dead battery in one hand and phone with a partly depleted battery in the other hand. I want them to both charge while I'm sleeping.
This separate case/charger does not help me.

No offense, but I believe you don't get it. You say: "I need to charge my phone AND the battery". I should ask you then, do you still need to charge your phone and the BATTERIES (this is the plural, meaning two or more) should you go by my suggestion?
Either, or, if you're such a heavy user and you find yourself at the end of the day with 2 or more depleted batteries on a regular basis, then this becomes even more handy - admittedly, yes, using a second wall plug...or, again, if you're such a heavy user, then buy a 3rd OEM battery - case solved. (1 charger, 2 extra batteries, 1 USB cable, 1 wall plug)

You obviously didn't read my whole last post. Otherwise, you would understand that saying "I need to charge my phone AND the battery" is a short way of saying "I need to charge the battery that's in my phone (but not totally dead yet) AND the battery that I depleted earlier in the day."
And if I added a 3rd OEM battery (which you would also see that there is no need for, if you read my whole previous post), it still would not change the fact that, at the end of the day, I have 2 batteries I need to charge and only 1 wall charger to use. So, the separate case/charger still does not help.
If I charge the battery in my phone and then want to use my one and only wall charger to charge the battery that's in the case/charger, I may as well just swap the batteries and charge the second battery in my phone. Thus, I would save running down the battery that's in my phone while the other battery is charging in the case/charger AND I would save spending $50 on the case/charger when I just used my coupon last night and got an OEM battery straight from Samsung for only $20.

OK, now I did get what you were saying (admittedly, I didn't read the whole post initially) but I still believe that carrying a second set (wall charger + USB cable) would render a better overall usage time without compromising on convenience or quality (again, due to using a certified OEM battery). Think about it, the only "compromise" you're making is carrying another set - which is nothing, both in terms of money and used space/volume.
So, your on-the-go package would consist of: 1 Samsung charger, 1 extra battery and 2 sets of wall chargers/USB cables.
Now, we're getting somewhere!
Your alternative would cost me something like $70 for the case/charger (w/battery) plus a second AC adapter.
My alternative will cost me less than $30. $20 that I already spent on a second OEM battery, plus less than $10 for a wall charger like this:
http://www.ebay.com/itm/Charging-Cr...l_Phone_PDA_Chargers&var=&hash=item27d35082af
And I have less "pieces" to carry around.
Of course, the cheap wall charger won't charge the battery as quickly. But, I have been using a charger just like that for my Rezound batteries for a while now and it always seems to manage to get the job done overnight.
However, the PREFERRED solution is what I asked about in my OP in this thread. I want a dock that will supply full power to the phone and a spare battery at the same time. As I posted later in this thread, it now seems that most any charging dock should supply full power to the phone (as long as the AC adapter is providing 2A). Those docks still won't probably give full power to charge the spare battery, but I can live with that. So, with a dock like that, I would carry the same number of "pieces", but I'd have the advantage of having a dock to prop my phone up next to the bed, so I can see it.

I can 100% attest to this NOT being true. I have my OEM Samsung S4 2A charger hooked up to my Seidio Innodock Jr. at it receives a MAX of 1020mA. Yes, I realize it isn't the exact charger you are looking for since it doesn't have the spare battery compartment, but Seidio is NOT being truthful to you when they say that it is "a passthrough" dock. Just a heads up!

What are you using to determine your max of 1020A? Galaxy Charging Current? Battery Monitor Widget?

I have both and they do not display the same data. As far as I can tell, GCC shows the actual full incoming current. OTOH, BMW shows the current being used to charge the battery.
When I plug in my OEM charger, GCC shows 1900. But, if the screen is using 100 and other stuff running is using another 100, the BMW would only show 1700.
So, as far as your post about the Innodock, if GCC shows 1020, then that's what I would believe. But, if it's BMW that's telling you 1020, then that could simply be because there is other stuff using almost 900 mA of current.
For the record, I looked through my BMW Usage log from last night when my phone was on the charger. The log shows every 5 minutes, I think. It only had one log entry where it showed 1992. All the rest were in the 1500 - 1600 range or less. And the phone screen was off that whole time.
Maybe I'm expecting too much, but the way I understand Qi wireless charging is you should be able to use any combination of transmitter/receiver you wish and it should just work.
Well, as I'm sure some of you are aware, that does not appear to be the case with the Note 4. I have tried two 3rd party receivers with different bases and have been unable to achieve any sort of consistency.
http://www.amazon.com/gp/product/B00PUA06TA/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
http://www.amazon.com/gp/product/B00OFKS66G/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
Above are the 3rd party receivers I've tried. You either have to off center the receiver with the base, or find a sweet spot that makes it look like if you so much as sneeze the wrong way the phone will fall off. NOT ideal. Most 3rd party receivers I have looked at employ a similar design.
Or you have a situation like mine where a base just won't work due to alignment issues. This is the case with the iOttie Easy Flex Wireless Car Charging Mount. The coil in the receiver sits too far to the left (screen facing you), and there's no way to align with the coil on the iOttie properly.
Here's the funny part. I have ZERO issues with the OEM Charging Cover. This thing where Qi is supposed to be universal may be true, but there are strings attached. Until there are no strings, I can't see how phone manufacturers can take it seriously...
I hope that the upcoming Galaxy S6 handles this better than that. It looks promising. It wouldn't be the sole reason I switch to it, but I can do a slightly smaller screen, don't necessarily need the pen, but they are nice. I just wish wireless charging was handled better....
I use the OEM Wireless charging cover and a Nokia base. I have had no issues at all. I would stay away from those cheap Chinese adapter coils. They seem very easy to break, they don't fit well with the stock cover, and are more prone to errors. They only sell for a couple dollars in China so don't expect much.

Wireless charging is not as fast as wired charging but it sure is convenient. I hate having to plug and unplug the phone all day. With wireless charging I just make it a habit to always leave it on the charging pad when I can. That way my phone is always at 100% when I leave. My OEM fast charger is still in the box unused. I got a deal on the Nokia pads a year or so ago and only paid $5 a piece for them direct from AT&T. At that price it's easy to place them in multiple locations such as the living room, bedroom, office, car, etc.

I have the same QI pad in ur first link. Works gr8 on mine. Now I'm using a different receiver. The first one I bought was the same slmpwrcard u got. Lots of issues with it, until it just quite. When it was kinda working, hit or miss, I measured the voltage the receiver sent to battery when connected with charger. It was low. Should be 5v, I was getting right at 4v, now it only puts out 1.7v, and won't even work. Below is the one I bought to replace. Works perfect! http://www.amazon.com/gp/product/B00P48BIFY/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
I have 7 QI chargers, and they all work well. By the way, the QI pad u linked is a 3 coil. Also it only makes sense u may have to put the phone on QI charger a lil offcenter because the coil in receiver is offcenter.....
I bought the Yoo Tech wireless receiver and LagaLake wireless charging pad. There's a slight bulge in the back of the phone and I have to put the phone on the charging pad slightly off center. In the end, it was more work than just plugging the phone in. So, I'm back to using my fast charger. I'll have to get the official Samsung wireless charging back and see if it works better.
I am looking for a battery case (yes case, I don't want any external battery pack) that has decent protection and supports QC 2.0 when charging the phone thru whatever pass through micro usb port there is on the case. I don't really care how fast the battery in the case charges, I just want to make sure that I won't be shafting my quick charging capability by putting on such a case.
Did you find one? I came across this, FYI:
"A 5 Volt battery (which all of them are) isn't going to give you a quick charge, so none of them are. You need 9 Volts to quick charge using Samsung's method. Give iit time and companies like Anker will probably come out with special packs for Samsung."

Incipio's Offgrid supports Quickcharge 2.0 passthrough. http://www.incipio.com/cases/samsun...-extended-battery-case-samsung-galaxy-s6.html

@RedXXII - that is freaking AWESOME! I battery case that 1) allows Adaptive Fast Charging pass-through, 2) allows NFC comms, and 3) PROVIDES FOR USE OF STORAGE CARD!! GENIUS!
I didn't see where the second one allowed pass-through, but I'm knackered so I may have missed.
The Incipio Offgrid is $70 on eBay. If it'll allow Qi charging too, I'll buy it in a heartbeat! Thanks for sharing that info!
[EDIT: the lone commenter at the bottom of Incipio's page explicitly states it will not work with wireless charging. Since it allows for NFC, I wonder if the other wireless charging has more "battery case punch through" abilities.]
@bwb8771: I actually have two Samsung Wireless chargers coming tonight. Since I still have my Incipio OffGrid, I will check and let you know. I also had a Powersuit battery case that allowed QC passthrough but unfortunately, it did not hold up well in a drop test.
@RedXXII - I'd love to hear what you find!
@bwb8771: Unfortunately, it does not work through the case. I have two of the Samsung Official Wireless chargers. Sorry.

not saying its not nice its just not a true quickcharge battery case output max is 1 ma and i am only getting 433ma same when I wireless charging so its miss leading saying quick charge.
okay update i am a little bit happier when its connected to samsung oem quickcharge it only charges at 433 ma but when disconnected and running on battery case it jumps to almost 2 ma which is wierd since max output is only 1ma but phone is charging fast so not too bad
I think you might be mis-understanding what Incipio is relating. They are only indicating that their case will ALLOW (not provide) quick charging through their hardware.
That is to say, if you connect the proper 15-watt AND proper micro USB cable, the quick charging of the phone will occur with the case in place.
Would you agree, @RedXXII ?

nope quick charge does not work "pass-through" when you have the case on as stated in the the message I left earlier it will charge the phone at .5ma ig if case connected to charger but, if you have the adapter unplugged from the case it charges the phone at 1ma or more the battery case even charges slower when connected to the phone.
but again i bought the case and it charge as fast as my non quick-charge adapter when not plugged in the only thing is that the phone and the battery case both charges slow when battery case is on phone

The cord that works fine without the case for fast charging doesn't work right with case on (think case doesn't see it as a fast charge device) so i decided what the hell switched the cable to the one in the box and now its charging fast. so use the cable provided with the case for fast charging to work it seems
Mine worked with any cable I used. It is dependant on the brick that you plug the cable into. Do you have any pictures of the case? I'm trying to figure out if I have a defective one. Mine will not close at the top. There is a noticeable gap.

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.

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!).
