wireless charging

hi
could anyone recommend a wireless charger suitable for yota phone 2 which can be purchased in uk
never bought one before but guessing that there must be a specific output mA/h and frequency ?? that must be compatible??..
seen lots on ebay suitable for galaxy and iphones but dont know if compatible
thanks for any help - (nothing on yota site to buy)

I've bought a Qi charger like this one:
http://www.amazon.co.uk/Wireless-Charger-Google-Samsung-BC252R/dp/B00FEAH0WW/
I use it mostly to recharge my Moto 360 smartwatch, but I've used it with the Yotaphone 2 as well, it seems to work fine.
The nice thing is that it's really compact, although it may not be what you're looking for.
I think that basically any Qi charger should work fine, I'm not aware of any frequency/voltage/output issue when using Qi chargers, although those sold online usually claim compatibility with a specific set of devices.

Nice

I can confirm that the Qi charger works well, the Yotaphone does automatically predict that the phone will be charged in a ridiculous amount of time, like 4x as fast as using a high current cable charger, but it does seem to be the fastest way of charging the device. My charger was from eBay and didn't cost a lot about GBP7.

Is there no official wireless charger?

There's the official wireless charger sold by Yotaphone on their website, but it doubles as a portable USB/Qi battery charger, so it's definitely bulkier than most Qi chargers found on the net. It does work as expected, though...
I've been using this for some time now, but I rarely use the Qi function (I often use my phone while charging it, which requires the USB cable unless you can tap the phone's screen without moving the phone on the Qi pad, which I consider on the slippery side).
Also, the bulk/energy capacity of the official battery isn't the most impressive I've seen, wchich is to be expected since they had to fit the Qi electronics on top the battery cell under the cover.
Overall, still a useful & stylish piece of hardware, though...

I bought a Wireless Charger from Samsung and had the same problems which some of you described. The Phone started charging and then stopped with a blinking charger after 20 Seconds.
My solution was: Since this was a QI Charger with an output of 2A, i made the error of using a USB Charger with output of 1,5A. I switched the usb-charger and used one with an output of 2A and connected it to the QI Base.
And now it works. So my suggestion: Use a Charger with 2A.

My very cheap Chinese wireless charger is now working well after I gave up on it for not charging. As in other cases, the yotaphone has a mind of its own and takes a few days to change.

I bought Spigen Wireless charger from Amazon UK. Though Yotaphone detects and charges, I see the below issues
1. The charging time from ZERO to 90 takes around 3 hours. The remaining 10 percent takes ages (more than an hour)
2. When the phone is charging and if the screen turns OFF, the charging stops which makes the screen turns ON with LOCK Screen. Again the charging starts and this cycle continues. I had to use an app called Snoozy Charger which minimizes this issue (by turning the screen OFF when charging is detected)
But, one good thing I noticed with this ultra slow charging: The battery life looks much better. For example, I had a screen time of 45 minutes before the charge dropped from 90 to 87.

If somebody need original Yota mobile charger, I can order it from Yota directly.

Well, since the thread has already been necromanced:
I understand fairly little about wireless charging but am I right to assume that all wireless chargers require the phone to lie on it on its back? Or is that due to my charger being too weak or cheap or whatever? I would love to charge the phone wirelessly with the epd being visible because, after all, that side has all my notifications and the time and what have you.

i use this one from the IKEA
works great on my YotaPhone 2

But does it work while the phone is lying on it's front screen? So that the EPD is visible while charging?

There is definately variations between chargers. A cheap ebay charger that I have does not work with some cases on my other phone with Qi charging. But a more robust three coil Nokia wireless charger works perfectly with it. Unfortunately my Nokia wireless charger does not work with YotaPhone face down... the charging light on the charger keeps blinking so it is close to charging but not enough. Some a little more powerful charger would be able to do it I think. Unless the desing of Qi only works on one side of the phone.

its charging while laying on the frontscreen on my IKEA SINGLE pad. I do not know for the triple one ??
Again the single pad is working great

Great it works on an single pad ! But I wanted to use it mobile..like in my car or motorcycle.
Sadly i know now it doesn't use an usb kind of charger but an 19 volt (??) adapter.

The only trick is to supply min required amperage for the charger requirements. You can find exact output values on the wireless charger. General manner: input amperage must be near/high as far as the ouput amperage. My Chinese cheap wireless charger output is 5V and 1.5A. And i can use it with 5v 1.2A AC charger problem-free.
Update:
i discovered that the cable is also an issue for the reason. If you connect a normal power support only cable to the Qi charger, you will probably be faced the problem. But if you connect a Data cable, you can use your PC's usb with your Qi charger. I can use it now like the way.

How can I disable display wake-up and stay-on, if QI-charging? (Android 6)

Wireless Charging issue after latest security update

Has there been anyone else experiencing an issue with the wireless charger since the last security update.
Now instead of charging the phone like it did before, it just holds it at the level it is at.
Anyone know why this is happening now, and how to fix so it charges?
Thanks.

You have gone to the menu item fast wireless charging?

Same Issue

Any Updates?

Hey, do the downgrade to PE1 with full wip, and put 100%, your working fast charging. Good luck. To me it helped.

I'm on PH7 and wireless charging works fine for me.

Wireless charging has never been an issue for me with any update. Might be purely coincidental, but you can also try a factory reset incase a setting or system file got skewed.

Have you checked the charger with another phone, or another charger with your Edge. It's possible the charger coincidentally failed at the same time.

My USB fast charging doesn't work. Wireless charging works faster than USB with different fast chargers. I have tried 6 of them and still not getting fast USB charging anymore. It is checked to fast charge also. All happened after the PJ3 update.,

Have you tried different cables, too? If the original charger and cable don't fast charge your phone, it's probably time for warranty service.

Quick charge no longer working since nougat?

So I have a couple of generic QC2.0 car chargers in my car and wife's car.. I've had them a year or so? They work fine on my note 4, and they did work on my my S7E while on MM.... I've noticed since the N7.0 upgrade they are no longer "quick charging"? The option is set on my phone, and it does quick quick at home with the wall wart but not in the car anymore?
Anyone else notice this since the nougat update?

I had this happen in my car after the last mm update... cleared cache, hard reboot, and pulled the charger out and put it back in. One of those fixed it. Probably the cache/ reboot

I'll try to report back, I tried the root method available for nougat and thru all the tinkering I fubar the phone. So I had (wanted) to wipe, factory reset and did a completely fresh clean install of N 7.0 nougat. So fingers crossed.

Well, I did a complete factory reset and fresh install of Android 7.0 Nougat, but my car charger is still no longer quick charging my S7E on N. I don't know the make and model of the car charger I have with qc2.0, it's not a Samsung branded one.... I wonder if android 7.0 changed something on how it recognizes the qc2.0 chargers? The house (samsung branded) still work but the car ones do not.
Sent from my Rooted Galaxy S7 EDGE on Android 7.0 Nougat, here's the instructions how to do it!

I would be suspicious of the cable more than the charger itself. I've had multiple 3rd party cables that (for lack of a better term) seem to have got "fried" and would only allow standard charge speeds. Switching cables resulted in fast charge working again. Your phone itself detects the current as soon as you connect the cable, and if it isn't able to draw what it needs to fast charge - even from a QC charger - it won't.
FWIW - none of my QC chargers are branded. They're all Anker or Aukey.

That's a good point, I'm using the cable that came with the charger... its a good solid cable, but you know that goes I will try another cable - that's a good idea. I'll report back when I do. Thanks for that suggestion.

I had problems with fast charging not working until a reboot or leave it unplug for a few minutes then plug it back in then it works flawlessly

Since the new update mine and my partners s7 won't fast charge, we both have official samsung chargers, we've even tried family members chargers and still the same, I've been in touch with samsung and they just told me to factory reset the phones which I did and still doesn't work, hope it gets fixed soon!!

Absolutely check the CABLE as the culprit. I have an old 6ft Belkin micro usb 2.0 cable that only fastcharges half of the time I use it on my Aukey QC2.0 adapters. I suppose a few factors could be in play here: oxidation buildup on the terminals, worn wiring insulation due to heat and/or bends. Maybe I'm drunk. Lol

Forgot to update. I've tried a few cables none allow quick charging on the car adapter. They do charge at 2.0amp and those same cables will charge quick charge in the house.... So, either my car adapter has suddenly stopped doing quick charge or something mysterious has happened to my specific S7E.
I'll have to try with my note 4 in the car and see what happens.

Mines dont quick charge either. Now how the heck do 100k a year coders miss this? They had to knew

Was gonna start a thread about this issue a couple days ago. Been having issues with fast charging ever since the update. I would connect the charger, it would say fast charging but revert to normal charging. Sometimes it would say fast charging for the duration but be slow as balls.
I found that shutting my phone down and charging it that way does a fast charge fine however.

I wonder what changed? At least in my case, I have 2 QC2.0 car chargers, from different vendors... one is from ebay the other I bought at Fry's electronics - and neither will quick charge now. I guess whatever handshake happens to enable quickquick isnt present since the nougat upgrade oh well... I am glad to see others are having the same or similar issues - at least I'm not crazy.

Mine still fast charges on my qc2.0 vehicle charger after nougat. *shrug* ill post a link to the one I'm using in just a sec...

wireless fast charging not working.
Since the security update my wireless fast charging does not work on my samsung wireless charger. if i unplug it and plug directly into phone it fast charges fine. anyone else having that same issue? fast charge works fine with car and battery backpack fast charger too.
Erider

fast charging works with my car charger and at home I use the factory charging brick and cable which also works fine. I also use a wireless Samsung fast charger but I haven't checked it works on that being I only set my phone on there before I go to bed.

I had issues with Quick Charge right after Nougat update, Just got my SM-G935T from T-Mobile last Friday.
To fix it I had to clear the cache and disable and reenable quick charge under system battery advanced options. and everything started working fine again.
I also had issues with wireless charging on a stock Samsung "Fast Charger" and ended up having to replace the usb cable from the power adapter to the samsung wireless 'fast charger' it seems after the Note 7 issues, samsung put some quality control software in the nougat updates for the S7 and S7 Edge, and if there is anything slightly off things won't work because of the new samsung QC steps.

Go to Settings (COGWHEEL ON NOTIFICATION BAR)
Then Select "DEVICE MAINTENANCE"
Then SELECT "Battery" bottom left
Then go to "Advanced Settings" using the drop down menu at the top left (... vertically)
Toggle "Fast cable charging" turn it off reboot phone then turn it back on.
You can also just type "Battery" in the settings search then go to "Advanced Settings" that way.

wiping cache, disabling, reboot and enable didn't work on mine. Seems its doing it no matter how or where im charging it now. it says fast charging but it's not if you look at the amount of time its taking (approx 20 mins per 10%)

wireless charging stopped working after i flashed PHN Netherlands rom with odin...

i put my s8 on the samsung fast wireless charger and it connects for a sec and then just disconnet and it keep doing so as long as the phone on the charger but it wont charge
i tried flashing my original ILO ROM back but it didnt fix the problem
before i flashed the Netherlands rom i had diffrent charging problems like sometimes the phone stopped charging at 80-81%
i place the phone on the wireless charger for the night and when i wakeup few hours later its still not 100%
the charging on s8 feels slower then on my previous s7 edge which dosent make sense cus 3000mah vs 3600mah!
did i get a faulty device ?

UPDATE !
it appears the problem is with the charger since i tried a friends wireless charger and it charged fine

Newest April Security Firmware Update Broke Fast Charge

Hello everyone,
After a long discussion with Samsung and absolutely no help I have ended up here. I recently updated my firmware on my Galaxy S8 Unlocked SM- G950U(Sprint Network) to the latest build G950USQU2CRC5. After this update I can no longer charge my phone and have fast charging. This is with original cable and charger as well as other cables and QC 3.0 compatible charger. Interesting enough when I plug into my QC 3.0 power brick it tells me that the phone is pulling 5v 1.5amps (7.5w) when it normally says 9v 2amps (18w). Also, only my QC 3.0 compatible car charger will make it fast charge . WTF is going on? I have already gone through settings, soft reset and also cleared cache. Nothing seems to fix this problem. I also get (Slow Charging ) notification at times. Does anyone know a workaround or a fix? Is anyone else experiencing this same issue? I have called and alerted Samsung of this issue. Please help if you can.

I seem to be having the same issues won't charge at all with the Samsung fast charger but it will charge in the car and my USB outlet and a Chromecast charger. Updated this morning to the latest firmware, also unlocked gs8

Okay so what I have found out is even with the cable and a few setting changes it will occasionally say it is fast charging however it never pulls more than 5v which defeats the purpose of quick charge.

Disgusted...
Same here; disgusted with the entire issue... Pay good money, longtime loyal customer, trust now eroded... Even went through reformatting the phone, did not help; waste of time... Thinking of switching to iPhone...

It's the cable and/or power brick. Also we're still on march secuirity, Sammy ain't that fast.

I have the same problem, when I upgraded from android 7 to 9, I lost the fast charge, I'm trying to find a solution.
the usb port says it is wet.
when the cell phone is turned off it is constantly informing that it is wet and the phone is trembling.
when it is on, it charges, however in a normal way, without the fast charge
solved.
