Hi guys, I bought a usb Type-C wireless charger receiver from BASEUS and a Wireless charger and for some reason it´s not working on my redmi note 7
I tried with my friends´Redmi Note 8 and it works fine, but on the Redmi Note 7 don´t work.
Maybe some software problem/setting??
Thanks in advance

It´s a universal receiver, meaning all phones with usb type-c connection shoul work.

So it's wireless but you plug in a cable into your phone to charge it? Doesn't make any sense

The specs says: Output: 5V/1A...
guess 1A is way to low... I even doubt it works on Note 8

Yeah it´s low and on Redmi Note 8 the carge is slow but on Redmi note 7 there is no signal at all.
I installed Ampere to check the current but it´s the same as without any charger.

Because it's probably even below the indicated 1A and the relay does simply not kick in at such a low threshold ... which is even a good idea to protect your batteries being charged at such a low amperage, I wouldn't go under 2A

Current doesn't affect battery. If you loads the mobile with more current, it only takes the amount it needs. If the load is very low, it lasts more to be charged and probably the charge is refused if it's programmed or hardware controlled in that way.

It does very much. Specially in lifespan...
But his amperage is to low which leads to sulfation...

I'm using my phone with crdroid rom and have battery charging information on lock-screen:
Charging from 5V/2A charger, I get around 1700mA current. Using laptop high current usb port, 1200mA.
The lowest charging current I get from old usb port (slow charge - 213mA!). I think the point is the voltage to remain over a limit.
Maybe that wireless charging adapter is defective or use a weak circuit and don't provide the voltage level needed for charging circuit in the phone.
For battery life, the lower current is better than fast charge, but if the charge controller is working properly (controlling the current & heat) should to be small difference.

High current is controlled, low current is better. There is no sulfation in lithium-ion batteries. And sulfation is due to prevent full charge, nothing about current. I'm sure about that, I have finished in this thread.

I plugged my OPO into my Find 7a VOOC charger at 1:04AM and I was at 8%, at 1:24 I was up to 29% now at 1:32 I'm at 36% so it is charging at 1% a minute And just so you guys know the quick charge will charge quick until the phone gets to a certain temp and then charges at normal rate. I guess this is to prevent heat damage
Heeey im so glad to know that!, but I worry about being damaging the battery by charging it that way, do you think it's possible??

I wonder then, if, in theory, cooling the device with some sort of water-proof ice-pack might mean you could quick-charge it all the way.
So the VOOC charger has a standard MicroUSB port? I wonder if maybe you can grab an app or a widget to tell us what its actual power output is? I use a 2A charger with my N5 and it charges pretty damn fast. Not 75% in 30 minutes as the VOOC charger claims to charge, but pretty quick nonetheless.

Actually it's 4.5A, but based on OP info (1%/min charge rate) I think Opo is limited to something about 2A/hour. Probably a 2A charger will charge at the same rate as Find 7 charger (4.5A).
My S4 can fast charge up to 1.9A/hour. So in an hour and half I have full battery.

It's not standard.
As stated by another poster, 2 extra pins (probably to deal with current limits) and also uses two pins (probably D+ and D-) to communicate between charger and phone. (This is very different from normal chargers, which just short D+ and D- together)
That said... IIRC the VOOC charging is supposed to be faster than what graffixnyc indicated. It may be only going at 2A in the OPO. I need to look through the kernel dmesg of my f7a to see if there are any "telltale" signs of VOOC being used in a dmesg.
You could install something like Battery Monitor Widget and see how many amps it's pulling.

It's confirmed to be working, but I doubt it's working with Opo the way it works with Find 7a.
I bet your Note 3 charger charges OPO at the same rate/time that Find 7a charger does.
There is always Qualcomm quick charge (2.0) which is supported by Snapdragon 801.

The Find 7a charger utilizes 7 pins vs the 5 pin standard for the micro USB.
This was found to exist in both the Find 7a and OPO (Reviewed Samples).
Though Carl stated on reddit that the production model will not have the special "7 pins", the sampled OPO devices did and was shown in a teardown.
So for one, the Note 3 charger is distinctly different than the Find 7a charger.
And two, though the sample OPO devices may have 7 pins, the production models may not.
Just hoping that the production models have 7 pins to utilize the rapid charge feature.

The USB ports on both devices look exactly the same.. there is a post on the OPO forums where a guy confirms (from a teardown) the OPO has the extra pins. However, I do notice obviously that it's not charging at the rate it charges the 7a but it's charging quicker with the VOOC charger than it charges my m8. @Entropy512 is it possible that there is also something in the software that fully enables VOOC charging?

You're right, I just saw some pictures of teardown and it has 7 pins indeed. But based on OP charging rate (1%/min), I concluded it isn't working like VOOC, which charges 75% in 30 mins (2.50%/min).
Oppo Find 7/a manual says that the charger can be used in other devices and it will be limited to 2A unless it has a VOOC chip if I remember correctly. So, this is why I think your Note 3 charger (2A) is equal to Oppo 7/a charger (4.5A with VOOC support and 2A for others) when used in Opo.
Besides, Oneplus didn't make any advertising expliciting VOOC support to Opo. I think it's a very rare feature in mobile world to be hidden.

I think Opo has fast charging on by default. M8 might charges at about 1500mah while Opo charges at 1900mah (I'm just supposing).
Try to enable fast charge to your m8. I believe it will charge as fast as your Opo.

There are some software changes, and in fact Oppo tweaked some of those settings on the F7a: https://github.com/oppo-source/Find...728e48ea4f50baaf1fd9e51cc7ae59d362788e#diff-5
hey... wait a second...
Those changes aren't for the F7a at all! The OnePlus Edition is the one with a PIC1508, and in the file with the compiled firmware - that's the Find7 OnePlus Edition section of the file!
It looks like in the original PIC firmware, the current setting was reduced for the Find7OP and they increased it for the OP with that patch - which might not be in the current CM11s build.
I'd do:
A/B comparison of the VOOC charger with a standard 2A MicroUSB charger
I might be able to get you a mostly-working Omni build later this week since the devices are so similar to play with, that will include the above Oppo tweak to the Find7OP

Hey guys,
I just plugged my note 4 into my car charger (anker charger, oem note 4 cable) and couldn't get it to charge. It charges my note 3 no problem.
I also have no problems charging my note 4 with wall chargers.
Any help?
I've got the "Anker® 18W / 3.6A Car Charger with Built-in Micro USB Cord for Android" and it's actually CHARGING my Note 4 when using GPS navigation and playing music! My Note 2 wouldn't charge, but it would hold charge under the same conditions.

I actually can't find it on the charger itself or even Amazon. It's relatively new, I thought it was a 2.0/2.1 amp charger (2x USB). Definitely Anker though.

Are you using both usb's at the same time? If so, it's splitting the power, so you'll get a slow charge.

Using an afer market 2.1a charger and an S3 cable, charges just fine.

I believe Samsung has stated it's a 9v charger instead of the conventional 5v charger.
Did some more research and found this:
http://www.incipio.com/chargers/car-chargers/quick-charge-2-0-single-port-usb-charger.html#
From the Engadget review, "I clarified with Samsung that it chose a proprietary solution instead of licensing Qualcomm's QuickCharge tech, but it insisted that you could still use QuickCharge 2.0-compatible chargers to achieve the same results."
Also from http://www.samsung.com/sa_en/support/skp/faq/1063730?CID=AFL-hq-mul-0813-11000170
[FAQs] Smart Phone : Galaxy Note 4- To use fast charging, what kind of charger should be used?
Fast charging uses battery charging technology that charges the
battery faster by increasing the charging power. The Galaxy Note 4
device supports Samsung’s Adaptive Fast Charging feature and
Qualcomm Quick Charge 2.0.
To use Fast charging on your device, connect it to a battery charger
that supports Adaptive Fast Charging or Quick Charge 2.0.

Hi guys,
N910C with Exynos here.
I have some questions for you guys.
1) Is it beneficial to use a generic (but good) 1/2 A (amp) 5 V (volts) charger over the Samsung charger?
2) What happens if I leave "fast charge" option on? Will it charge faster? Will it try to?
3) When using the provided Samsung charger, is it better for the battery to leave the "fast charge" option off?
4) Is the fast charge (or any fast charged charge) as good and efficient(?) as a 'slow' charge? Will they last the same?
5) What if I turn off the phone, is it going to "fast charge" by default when using the the provided charger?
Thanks in advance guys!

No. It won't do any harm, it will just take more time to charge your Note.
2) What happens if I leave "fast charge" option on? Will it charge faster? Will it try to?
Click to expand...
Click to collapse
It will charge slowly. Reason: Fast charging uses a slightly higher voltage for transferring the charge to the charging circuit. That's to keep the amperage low, so the tiny wires won't overheat. It's just according to the formula W = V x A: You can increase the wattage by increasing the amperage (heating up the wires) or by increasing the voltage (keeping the wires cool).
That's the reason why many countries don't use 110 V but 230 V - to decrease the burden on the electricity lines as you can then safely transfer more watts through the same lines. It's a kind of safety measure.
3) When using the provided Samsung charger, is it better for the battery to leave the "fast charge" option off?

No. Fast charging does not reach the safety limits defined for our battery.

Yes. Just imagine it this way: If you fill your car at the fuel station slowly or fast - does that show any effect on your car's range ? - No.

If you enabled that in the settings, yes. Otherwise: No.
One question is missing: "Does Fast charge harm my battery if charging under hot climate conditions?"
Answer: No. There are temperature sensors in the battery, decreasing or even stopping the charge if the temperature gets too high.
Short: The difference between slow and fast charging is - slow charging charges slow. And that's it.

To be honest: You already answered your own question - by asking your questions.
If you have a look around XDA, you'll find countless threads discussing the "problem" - many users fear Fast charging may harm their battery.
Some users even believe the battery would be charged with an overvoltage (as that voltage is mentioned on the rating plate of the charger), thus causing damage.
No, not true. That higher voltage is just used for safely "transporting" the charge through the wires by keeping the amperage low. After that, the charging circuit will regulate voltage and amperage down to healthy levels prior to reaching the battery.
But people get misled by many self-proclaimed "experts" (which will surely show up here, too) praying that Fast charge is a work of evil; just wait.
That's why Samsung made that feature an option, not a rule. A courtesy for the overcautious.

I'd stick with the original Samsung batteries. They had problems in the past (deforming, bulging S4 batteries losing almost all of their capacity - I had one of those myself, got exchanged for free), but I guess they solved the problem.
Reason is: Li-Ion batteries may have different charging parameters; like maximum allowable current.
The Fast charger was made specifically for the Note 4s battery. If you buy a different type, the fast charging current may exceed the current rating of a third party battery, leading to highly unwanted effects including destruction of the battery.
This is not too likely because each battery has (or should have) a built-in charging circuit for limiting the current, which even switches off charging if the battery's temperature reaches unhealthy levels. But it's still possible, depending on the battery type and manufacturer. I wouldn't place any high bets on charging circuits of cheap batteries; everything's possible.
That's why it's best to stick with original batteries - at least in this case.

Absolutely correct, the phone doesn't have FAST/QUICK charger technology...
However a higher ampere charger like 2A could still charge a phone faster, hence my query above
Are you sure it takes 90 minutes to fully charge with stock 1A charger as mathematically it's not possible
3000mAH/1000mA=3 hours
Or
3000mAH/1.5H=2000mA or 2A
Pehaps you are using a higher capacity charger? That would explain it...

The time of charging with 2A is the same using a original charger with 1A. The limit is inside at the circuit control of charge.

Thanks
This is the 3rd comment I have seen from a user confirming 1A is the max phone can utilise
Such a shame as I think this is the only real flaw with this phone, otherwise it's a great device...

Yes, you have right.
We can put a 10 A capability charger at our device, but charge control circuit is doing his job and let device charging with 1 A max, even if is there 10 A disposable....
Maybe with some command in hidden menu or with some customized firmware is a way to override this limitation.
(At LG 4X HD is in hidden menu a command that enable fast charging).
Where exactly does one have to change what in the root directory?
I want to test this time.

I doubt we will be able to find any such software hack to allow fast charging.
There just isn't enough development going on for this phone for anyone to discover and share such information
https://www.androidpit.com/huawei-p9-lite-review
Above review was found by another user on this forum where it's mentioned that phone supports 10W (5V×2A)
So this is what I am hoping is correct and is verified by someone who owns the phone already

That would be really very nice, I would be really happy ).
Maybe fast charge working with another type of charger: Huawei 9V2A Quick Charge Travel Charger
Instead of 5V1A(5W) or 5V2A(10W) with 9V2A(18W) charger, the charge circuit control will sense 9V instead of 5V and maybe switch to fast charge...
2 Amp charger are only needed if you are using a 2 or 3 meter USB wire.

I dont think so.... the options you mentioned actually mean QC 2.0 technology which we know for sure isn't available in P9 lite
There are few mentions of phone supporting 5Vx2A online; one such link shared by me in earlier post...

The P9 Lite doesnt support any sort of fast charging. The ability of a phone to charge faster depends on it's hardware and the use of a fast charger. However, with a 2A charger, it slightly decreases charging time since the phone pulls approximately 1050mA. Be careful not to use a charger thats higher than 5V as it will fry your circuitry.

Where did you get this 1050mA spec, did u measure it yourself? This could be true as well, as fast charging is not observed by anyone until now except few online sources which state otherwise...
The part about damaging phone is inaccurate as QC 2.0 or 3.0 chargers are reverse compatible with old devices which support 5V only, the phone and charger never switch to 9V/12V/20V mode as the technology isn't there...

I did measure it myself with the aid of a friend. By the way, I was referring to a standard 9V/12V charger, not the QC charger.
According to my knowledge, the voltage is like a gateway to your phone, your phone pulls the current. Hence, if you use a standard charger with higher than 5V, you'll most definitely burn your circuitry. BUT....if you use a 5V charger with an abnormally high amperage, the phone will only pull the current it needs.

Great that you actually measured it, I am assuming using an external device...
That would confirm it without doubt that online reports are incorrect and phone can't charge above appx 1A

So just a quick question.
This means that for a phone to be able to pull 2A, is not just software control?
It means that the hardware has to support the ability?

I believe that is true. Although, most fast chargers (like the samsung one) only supply 1.67A at a higher voltage, normally 9V. This combination increases the output wattage of the charger....Like i said on my earlier post, the voltage is the gateway to the phone while the phone pulls the amperage.
Can i charge my s8 with my laptop charger which also has a USB type C pin?
It is charging and it's faster. Phone gets slightly hot.
Should I do it? Or will it harm my battery?

The device will limit overcharging My fast charger gets pretty warm,Well my device does I never cared for fast charge
Always been taught slow trickle charges will prolong battery life in the long run....

I wouldn't see why not Your device has its own loads of safety Fail safes that would disable charging if something was afoul
Yo man. You are able to charge it using your laptop or whatever type C you have. I did sometimes using Macbook Pro type C charger. As others said. I believed the device fail safe is there.

What is the output voltage on the laptop charger? It should have it printed on the charger unit somewhere. This is very important.

I Apparently read incorrectly, I thought you meant charging off your laptop not the laptops charger itself.... Normally laptop chargers are 15 to 19 volts which is way to much but again I am pretty sure the devices fail safes would kick in and limit charging....
You could, it should still limit the charging rate to 15W.

Nope, it depends what the voltage is. Your statement is correct if the voltage is either 5V or 9.6V, as those are the voltages used by the phone.
But laptops are usually way more than that. And if OPs one is higher voltage, it's going to kill the battery and potentially cause cause it to swell up and expand.

What about other way around, I have been using a MacBook Pro charger on my S8, what if you use a Samsung quick charger with a laptop?
