Hi folks just picked up a note 7 today, anyone happen to know why a nexus 6p charger won't kick the phone into fast charge ?
I remember coming from the note 5 the cable would always crap out, my 6p was always good
It will charge the phone fast just not fast charging fast.
I just used it on my note 7 a few hrs ago. It took about 1H 50 min to charge fully from 2% to 100.
There is normal charging which is slow
Rapid charging aka Nexus 6p style which is pretty fast
And Fast Charging which is fastest.
The 6P uses USB spec fast charging for 5V/3A. Qualcomm uses Quickcharge which is different. The Note probably will not utilize standard USB Type C charging at 3A.

I received the Nillkin Magic Disk charger I ordered a few days ago.
It's the first wireless charger I have owned or tried. I have the disk connected to what is supposed to be a 5V / 2A adapter.
It took 7 hours to fully charge my Nexus 5 from 6% with the Magic Disk. This seems like way to long to me and if it's normal, this severely limits the usefulness of wireless charging. Neither the charger nor the phone seemed to get warm at all during charging
How fast is wireless charging supposed to be? Does this vary between different types of Qi chargers?

Should be much faster than that, about half an hour longer than stock wired charging with the Nexus 5 adapter/cable.
~2.5 to a little over 3 hours depending on the charger.
If you are using a decent 2A adapter with your charger, it may be your USB cable. Some cables out there are quite crap and despite using a high amp adapter will keep the settings as USB (as if you're plugged into a computer port) and charge at around 500mA max if you're lucky.
In your case, the USB cable may be doing that, and severely underpowering your Qi charger, which will end up charging your phone at like 300 - 350mA. Stock wired by the way charges at ~1050mA by comparison. This could explain why your charge times are over 3x as long.
If you have your stock USB cable that came with your Nexus 5, try testing it with that to see if there is an improvement.
Mine charges at 600mA.

My Nexus 5 charges at roughly 1000mA with its wall charger. So I guess wireless will be 40% less efficient...

Depends on the Qi charger and its output. Efficiency is generally around 70 - 75%.
I have a few 1A Qi chargers, and they charge at roughly 740 - 760mA when charging at full speed.
Hi Guys.
First off, I'm new here, and I did use the search function. However I did not find anything to my problem in particular.
I have a Lenovo Tab 2 A8-50 (it sucks, I know that by now).
I have 3 different original charger with the original cable that came with the devices.
1x Samsung Galaxy Note 5 - Adaptive Fast Charging - 5V, 2A.
1x iPad Air - 5.1V, 2,1A.
1x Lenovo Tab 2 charger that came with the device - 5V, 1.5A.
If I use any of those 2 other than my Lenovo charger, the charging process is incredibly slow.
For example, with the Lenovo 1.5A charger it takes about 90 min to charge from 25% to 100%.
If I use the Samsung or iPad charger, which have 2A , it takes 4-5 Hours!!
How is that possible that a 1.5A charger , charges faster than a 2A or 2.1A charger? Especially by so much?
I thought a higher Amp charger gives you shorter charging times?
Thanks
hey guy, I bought a pixel 2XL last 2 weeks and I didnot have fast charge adapter of google so i used adaptive fast charging of samsung. Is it OK? because when i took that phone, i checked it have 3200mAh and after two weeks, now it have 3150 mAh on battery. I want to know that pixel 2xl fast charging is possible with Samsung fast charger
If I recall correctly is not compatible, you may not charge at low speeds but I highly doubt it's using fast charge. The Pixel 2 XL uses USB C Power Delivery 2.0 for fast charging, most Samsung phones use propietary Qualcomm's Quick Charge technologies which are not compatible between them.
I've used a generic fast charge charging block with my 2XL and I get the "fastcharging" notification, so I'd presume it would work.
Don't ever use any other adapter that didn't support for Power Delivery. It will broke the charging port or some IC power, anything like that. Just saying. Better take 3rd party like anker or aukey that support PD.
Has anyone got warp charge 30 / 30w charging to work on their 9 pro? When I look at the charge speed using #8008 and logging the charge current with the screen off I never get over 1.2A or 1200ma. That is with the car charger and wall charger from one plus. My 65w charger will charge over 6A fine with the screen off. I tested the 30w chargers on my oneplus 7 pro and they work fine. I also noticed if I use a charger designed for PD my phone will charge at 2.0A / 2000ma. I find it strange the phone won't work in backwards compatibility. I actually get faster charging from my oneplus 5t charger that was only rated at 3.5A.
If anyone has a solution please let me know.
Because warp charge 30 can only negotiate up to the max of 5v. The warp charge 65 is 10 volts. The 9 pro phone uses a split cell battery which effectively splits and halves the incoming voltage and amperage for each cell so 10 volts become 5 volts each which would explain the much less than ideal charging speed.
Coincidentally USB-PD also can negotiate higher output voltage (I believe 9 volts) hence the compatibility to work with them.

I had considered the the 5v vs 10v but I thought one plus had mentioned the phone was fully backwards compatible. I really need to find a car charger that can charge the phone fast. I thought about buying the 50w OPPO charger but I cannot find one from any reputable place or even oppos site for sale. Right now I use my inverter in my work truck. If I could actually charger at 30w that would be fine for my needs but when using hotspot or GPS the phone doesn't even charge much at all when it only draws 1.2A. It takes multiple hours to charge 50% at that speed.

Never on the specs on the official product page for the warp 30 charger states it works with the 9 pro. Just settle on any 45+ watt usb-pd adapter and it'll get pretty close to warp 30 charger's max speed which would get you topped off in roughly an hour or more. Save yourself the headache and be grateful that's even an option as past OnePlus phones would only cap at 5 watts on any non OnePlus fastchargers.
PS, I wouldn't trust any marketing fluff coming from OnePlus as of late, they've been clickbaity and false hype inducing with bold but cleverly misworded claims since the inception of the 8 series and has been going downhill from there. My 9 pro is likely going to be my last OnePlus and likely last forray with android phones as a whole.
On the other hand..., wireless warp charger 30w from OnePlus 8 Pro works fine on my OnePlus 9 Pro.
I use it untill i got my 50w warp charger.
I would like to know if the OnePlus 5T's charger will be able to charge the S22 or is it better to get the Samsung 45W charger or some other make with the future in mind?
There is also the Samsung Note 8's charger lying around but that seems to be a 15W compared to OnePlu's 20W and not sure the Note 8's charger will work.
All chargers will work. OnePlus' super fast charging won't work since that goes against your typical quick charging spec, but if it'll charge. The Note 8 charger will also work, but will charge at your typical 15w speeds.
Skip Samsung's 45w charger and just get a third party 25w or 30w charger since not even the 45w capable phones charge at 45w consistently and generally throttle down to roughly 30w.
25W charger is all you need. I have the Anker Power Port for my S22 Ultra and it charges from 20% to 100% in 80 minutes. A 45W charger is only slightly faster. Not worth the extra cost.
Im using the charger that came with my A20 to charge my s22 using fast charge. works well when not using the phone.
normally I charge my phone while sleeping. but today I didnt. when I went to bed it was at 95%, when I woke up it was 18%....
Thank you for responding.
I also have a OnePlus 5T 20W charger, wondering if I can use that.

But 20% to 100% in 80 mins is bad, when I'm in a hurry to go out I should have enough charge on my phone but with this 25W charger, it is not possible. So I'm going with a 45W charger because I used Redmi K20 pro with a 33W sonic charger, it charges 0-100% in just 40-45 mins!!!
I have the HyperGear wall charger works great.
Isnt the Samsung S22 (Base one) capped at 25W max capacity. Only 22+ and 22U support 45W charging.
I too upgraded from OnePlus5T, the S22 doesnt charge with it and shows 5 hrs to charge fully and for some reason, the battery was discharging while connected to the 20W OnePlus charger. I dont think its compatible, ideal and safe choice would be to go with 25W charger from samsung for 1299 if you do not have any previously owned ones.
