Maxell air voltage qi wireless

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.

[Q] Nexus 5 and wireless charging.

Hi Guys,
I have a nexus 5 and I noticed that my LG WCP-300 continue to charge even when the battery is full.
The charger works fine with my Nexus 4, it stops charging when the battery reaches 100% capacity but not with the N5.
I'm wondering will it affect the battery if I keep it on even tho the device says "Charged" ?
Thanks in advance

Interesting. My Nexus 5 just arrived and I'll be curious to see how my LG WCP-700 charger handles charging the Nexus 5 when i get off work.

I think they finally fixed the wireless charging. My N4 would stop then drain down then start charging again. I never knew if it would be fully charged when I took it off the charger in the morning. I'm certain the battery will not overcharge.

Off topic, what is the use of wireless charging other than not using a wire to charge ?

Apart from the convenience of just putting down your phone to charge it will save your USB port from damage so if you need to fastboot for repair / warranty / general flashing you know it will be in good condition if the time comes. My galaxy nexus USB port broke, plugged in the charger and noticed it wasn't charging after a while and plugged the plug to see smoke come out the port and the phone was very hot! It may have caught fire if left. So now that phone has a dead battery, luckily its removable so could be charged separately with out the phone. The screen would turn on and drain battery too. I'd fully recommend getting one if you can, I intend on getting one in the future.

I aslo have the WCP-300 with my Nexus 5. I am experiencing the same thing.
I wonder why they changed the charging. I know my Energizer Qi charger also does this because the charging light always stays lit blue.

Wireless charging on Energizer
I have the energizer charging pad and noticed the same. My Nexus 4 would stop charging and if it fell back to 98% would charge again. The Nexus 5 just stays charging at 100% and I have read that it can damage the battery overcharging like that. Can someone confirm that for sure?

nothing on this?

Not unique to the charger

Just for the sake of clarification. The same thing occurs with the Nexus 5 using the Panasonic QE-TM101 which (as above) worked flawlessly with the Nexus 4. So it appears to be the phone (not the charger). And in spite of people assuring us that this won't damage the phone (battery), I can't help but think that the heat can't be good for the battery and if it wasn't "actually" charging after it hit that 100%, then what's generating the heat (it has to be actively charging to create that heat). I plan to do some controlled tests to see if the same problem occurs with my OWL (Qi compatible but not Qi certified) chargers, and see if the charger is cycling on and off during the charge period or staying in charge mode. But every time I've awoke in the morning the Panasonic charger has actually been charging (charge light on) with the handset very warm.
I'm afraid that if it's not cycling then over the long haul the battery (or possibly the phone) may suffer ill effects due to the consistent heat.

[Q] Terrible charge rate?

One of the things I loved most about my Nexus 4 was just how quickly it charged. And unlike my SGSII before it, it could even gain a charge while being actively used for Waze. Really great.
With the 5 I'm back to where I was. And thanks to tools I picked up during the 4, I'm able to see why more easily. Seems on the exact same chargers I used my 4 on, I'm easily pulling 400+mA less than the 4 did from the same device and same cable.
I haven't had time to draw a correlation yet, but last night at home on a multi-out adapter from Monoprice I was able to pull over 1200mA which is more than I've ever seen ANY of my devices pull before. But today, on the same model at my office, but with a different cable, I'm pulling around 200mA. Same as what I was getting in my car, which would frequently dip into the negatives, and that was WITHOUT Waze running. Also of note, in ALL of these locations it's being listed as "USB plugged" instead of "AC plugged." I'd say that accounts for the difference there, but the 1200mA draw was listed the same way, so I doubt it.
So, has anyone else noticed this yet and found any correlations between devices, cables, etc., so we can figure this out? Using more power than it takes in will not be something I can survive with and will definitely make this phone a less-than-ideal upgrade over the 4 in the battery life department. But it's pretty clear it's not impossible to get a good charge.
(and yes, before anyone asks, all of my adapters have jacks with a minimum of 1A out, and each also has a 2.1A port. Surprisingly, unlike my 4 which tended to draw LESS power from the 2.1A port, the 5 appears to be unconcerned by the difference, pulling the same poor number from both)

Yes, i agree with you. I just check today, charging my phone from the pc and it seems fast charge isn't doing its thing.

Well, I haven't even dared test it from a PC yet. All I can say is from wall warts and car chargers it's terrible. I can't imagine how bad it is from the limited PC ports. Although it's probably exactly the same, since it seems to be identifying all my wall outlets as USB connections.

Not too surprising. I've read other reports that it charges nice and fast with the stock charger, which is likely the same as the G2 charger since they share most of the same hardware. But that doesn't help with car charging or those of us who've consolidated into multi-port chargers.
When I get home I'm going to mix and match some cables and devices and try to narrow in a bit more. This sounds like the Nexus 7 (2012) goose chase all over again.

The USB/AC detection is done with a definied resistance. Some chargers don't meet those exact resistances (cheap resistors have a big tolerance) -> the phone detects it as USB.
The cable can make big difference, I've tested several different cables on the N4 once, charging rate was between 600mA and ~1100mA (which should be the max) on the same charger.
Maybe the resistance in the charger is right inside the resistance tolerance, so the slight difference in resistance between the cables is enough.
Since the N4 most probably uses a different charge IC than the N5 (I haven't checked tho), it could be that the N4 had a wider tolerance than the N5.
What should help are those charge cables , the one I'm using from Porta Pow can only be used for charging therefore ignoring the charger resistance -> phone should always detect it as AC(even on a PC). Another good thing about those cables is the big wire diameter. Or a kernel where you can force AC charging regardless of the actual source.("fast charge")

That all sounds pretty logical. Considering I got much better results with the Monoprice premium cables I used last night (which oddly, are much THINNER than the cheaper ones), I'm going to experiment with those this evening and see if that makes all the difference.
As for kernels, I'm not planning to root this one if I can help it. I managed to get through the life of my 4 without rooting, too. I know it's heresy on XDA not to root, and until I got Nexus devices I would have agreed. But since stock Jelly Bean I haven't felt that burning need to "take back" control of my phone. I seem to already have plenty.

I observed the same inconsistencies with the N5's charging behavior and did some qualitative tests. I've attached a screenshot with my findings.
The phone is clearly capable of charging rapidly. My primary focus is getting a high current off the car charger. Is there a way to force AC charging mode vs. USB charging, or should I focus on more quality cables / adapters?

Just did some additional testing of my own and found some interesting results. I didn't take perfect notes, but here's what I got:
With the Monoprice 4-port Wall Charger 2.1A 8856:
Cheap Monoprice cable: bad charging, fluctuating between -80A and 200A.
Cheap unknown cable: same as above.
Monoprice premium 3ft cable: 900-1200A.
Monoprice premium 6ft cable: 700-900A.
With the Monoprice 1A car charger 6765:
Bad charging with all cables tried.
With the Monoprice 2.1A car charger 8858:
Bad charging with all cables tried, with exception of Monoprice premium 3ft cable which had same low end, but occasionally bumped over 300A.
With 3.1 (split between two ports) charger purchased on Amazon (my standby for my Nexus 4:
Bad charging with all cables tried.
With Monoprice 2-port USB Car Charger 3.1A 10071:
Cheap Monoprice cable: Bad charging
Cheap unknown cable: Bad charging
Monoprice premium 3ft cable: 700-900A
So it looks like high-end Monoprice paired with high-end Monoprice pays off. Unfortunately there's a rather serious catch with model 10071: it KILLS GPS. At least it did on my Nexus 4, and other reviews reported it as well. I can't be certain yet about it on the 5, but the little experimenting I did in the parking lot showed some anomalies I didn't like. Which means I apparently get to choose between GPS killing my battery, or charging my battery killing my GPS.
Also tried Nexus 7 2012 charger with its own cable and got bad charging, too.

There's a pattern obviously, the 6ft to 3ft drop seems high but is ok I guess.
I've never seen such a picky device when it comes down to charging, usually it just works as expected ^^
Have you tried your cables on the carger it came with ? Or the cable it came with on your other cargers ?
Is there something with "AWG" written on your cables ?
@random_dgp: Well you basically have 2 choices: get a kernel with (force) fast charge support (don't know if there is one yet) or get a charger/cable combo which works.
If you're planning on rooting your N5 anyway I would go for the kernel way I guess, since the charger and the cable are fine most probably, they just aren't in the specs the N5 requires.

The first-gen Nexus 7 was at least this bad. Actually its biggest problem was it refused to even ADMIT it was charging (even though it was) off of most devices. In fact everything I just listed it would claim wasn't even connected to it. A few hours later it was full, but it refused to recognize it. 4.2 fixed that, but it was still slow off of most devices. This at least admits it's being charged, but barely is.
And no, I haven't tried the stock charger yet. I guess I will, but it's not a high priority since it doesn't cover my issues.

i dont know if you're making this up, or if i have a defective nexus 4 lol
before i optimized my N4 i was getting about 4-5 hours of screen time, but it took at least 3 full hours to charge. that charge time to usage time ratio was killing me.
i am having much much much better results with my N5. i have no reason to charge it through a USB port on the computer(are you using an USB 1.0 port or something?), but charging it with the charger that it came with, i get a full charge in about 2 hours.
my N5 will charge a tiny bit over 1% per minute(while on or off), until it gets to 80% and then it charges at about .5% per minute or something
if you're getting the same charge times on the wall charger then i think you might have a defective charger/device. testing this will also be a good way to find out if it's just a slow usb port too

Oh that's bad , I didn't know that!
Would just be the "reference test" since the stock charger should meet all the specs (and works fine here with every cable).

The problem he's having isn't about a computer USB port at all, the problem is that the N5 thinks it's plugged in a computer and limits the current to 500mA to meet the USB specs (and don't blow up some usb ports without a fuse somewhere) but in reality it's plugged in a wall charger.
His phone should be fine since it's working as expected on some carger/cable combos.
Btw. the N5 isn't pulling more current than the N4(both 1,2A), so it should charge almost exactly as fast/slow as the N4. It should even be a bit slower since the battery is slightly bigger I think.

I'm simply using the app Battery Monitor Widget. Really handy tool that solved some problems for me on the 4 with some weird charging situations. While I'm sure it's not insanely precise, it reflects my draining or charging rate well enough to show me what's going on.

I think you're missing the fact that I'm comparing it directly to how well these same devices charged the 4. So they're clearly not defective so much as the 5's requirements have changed completely. And USB 1.0 (I think you mean 1.1) isn't relevant here, as I'm not charging off a computer, I'm charging off a wall and/or car adapter. But sounds like we had very different experiences with the 4. I could charge my 4 off my Monoprice pocket battery in crazy fast time, and my phone was always full by the time I reached my destination in the car, even with Waze running (once I figured out I couldn't use the long cable I was using initially).

Would just be the "reference test" since the stock charger should meet all the specs (and works fine here with every cable).

Absolutely. A control of sorts. Might as well.
Btw. the N5 isn't pulling more current than the N4(both 1,2A), so it should charge almost exactly as fast/slow as the N4. It should even be a bit slower since the battery is slightly bigger I think.

Exactly. That's why I was surprised. There's no way it SHOULD be this much slower. Yes, I can see percentage adjusting slightly for the larger battery, but that's why I'm going by mA input instead, and my 4 was getting WAY better in the car. Although I don't think it ever got the 1.2 I'm getting with the Monoprice wall combo, so THAT's impressive. Now if I can just get that in my car without the RF interference and I can call it a day.

Oops, multiple responses and replied to incorrect one, but really if your recharge rate is that much lower v. n4 I'd say that your chargers or n5 are defective. It's going to take longer to charge the n5 obviously, and I have no idea what the max draw either can achieve as I've been strictly using inductive charging w/max 1A supply(as per Qi spec)... n5 takes longer to charge than n4, but thats to be expected by batt cap(and wear(decreased cap) of n4 batt)...
Subjectively, the n5 takes longer to charge, but not that much longer that I've noticed, again batt cap, etc. so...
Both USB/AC adapter chargers I know supply a max of 1.2A...

Neither I think, we don't need any mA values to see that something is wrong, android is telling us that it thinks that it's connected to a usb port while it isn't.
Of course if we would want to measure exact mA values we would need a different equipment, for cable comparisions in order to see a tendency, the values from the charge IC should be good enough.(IMO)

Well it looks like the N5 has a very low tolerance for AC/USB detection, I'm sure that neither his chargers or Phone are defective, the chargers just aren't 100%in the spec which is obviously enough. I'm sure that the stock charger would be fine.

Clearly neither is the case from my testing. The N5 charges beautifully off of the right combination of chargers, and all of those chargers charged the N4 beautifully. Neither is defective, but the N5 apparently has a different tolerance requirement than the N4.
Really, as opposed to anything being defective, it sounds more like a design flaw in the N5. It's WAY too picky about its power sources.

Mine charged REALLY slow the first day and that night. It also drained really quickly during that same time. I am now on my third day and it has long battery life plus it charged about 20% in 30 minutes on a car charger. Seems quicker than my S3.

[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:
http://www.androidpolice.com/2017/0...ill-degrade-less-quickly-than-the-galaxy-s7s/
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!).

General Wireless charging

Wireless charging is awful on this device. No matter what case (or even no case), my phone must often does not charge wirelessly. I've tried multiple chargers. I get the "connected; not charging" message. Sometimes it works, but seems to need to be in the exact spot. Even then, it often stops charging after a while or drains faster than it charges.
Any insight or solution to this?
This is a stock pixel 7 pro, bootloader still locked. Bought from Google store and activated on T-mobile.

What wireless charging pad are you using?

I was having all the same thoughts as you. Had a couple Samsung "fast" wireless chargers. However, bought a new one Costco that's not Samsung and it works as expected. Never have to realign or wake up to a dead phone anymore.

my rooted p7p with tq1a.230205.002
is charging well with wireless pads and wireless powerbanks.
always heating up p7p tho

I don't know why people like using Samsung but I prefer other brands
the backrooms​

My Pixel 7 Pro works fine using this 30w Wireless Charger from Amazon - Nanami 30W Max Wireless Charger
This is the only thing missing from the OnePlus 11 - but I don't care...

In my case, I figured out my wireless charging is unstable if my phone is in any condition where it might get at all warm. The Pixel 7s are just lousy at staying cool, and once the temperature rises to high 30/low 40C (which doesn't take much at all), wireless charging is severely throttled if not completely stopped. So if it's sunny out, I understand my phone won't charge in my car mount. The sun just makes it too hot, and it won't bother (no matter how cool I keep it in my car, direct sunlight on the phone is too much). If it's sitting on my wireless charger and I decide to try and use my phone while it charges, I understand odds are VERY high it will get too hot and stop charging. And if it stops charging because it has overheated, I know now to give up rather than keep readjusting it on the wireless charger, because even if it's not charging, if it's trying, it's still making the phone hotter, which is making it take even longer to cool down and resume charging. So I just take it off and don't bother putting it back on until it's gotten a chance to settle first.
It's finicky and irritating that their flagship has such lousy thermal control, but knowing that my wireless charging issues are linked to my phone's temperature has helped me understand how to keep my phone charged. Those who only charge wirelessly without ever trying to use the phone and only in particularly cool environments may never observe any wireless charging issues at all.

I noticed this too
I find Power saver with less brightness helps, but if it gets hot it's not charging at all

No problems with 2 different wireless chargers with a transparent case.
I measured the power usage with an external device and its mostly the charger uses 14 watts power between 0 and 80%. (don't forget the energy loss with this technology!)
No real overheating. But placing the device correctly affects the power draw a lot.

I agree. It's terrible, no matter what charging pad i use, it always glitchy.
Not to mention, the reverse charging won't work properly either. Plenty of time i need to recharge my buds while travelling to no avail.

I struggled with wireless chargers for P7P too, I tried at least 4 with varying degrees of success but ultimately I just ended up using some of the store credit I got for buying to the phone to get a Pixel Stand 2 and it works great.

I can happily say : MARCH RELEASE FIXED MY WIRELESS CHARGING ISSUE.
