I recently purchased one of the wireless inserts and a QI charging bad for my SGS3. I've noticed something pretty interesting, and I was wondering if anyone else has noticed this/found a workaround/things I'm crazy.
When I charge wirelessly on an AOSP-based ROM (Only tried 4.4 ROMs) the phone tends to get VERY hot (120F+) and will often stall, where it stops charging and just heats up. When I charge wirelessly on a TW-based ROM everything works as you'd expect.
TW does acknowledge when it is charging on a wireless pad vs. a normal USB charger, and I know that the two components need to communicate with each other, so does anybody know whether the code for this is missing in AOSP Roms? If so, any way to get it back in? I would expect (but could be wrong) that it would be in the kernel.
Hello xda,
I am looking for a charging pad that auto shuts off when my Note 4 is full. It is hard to find those kinds of wireless chargers. I am using a Qi-Infinity charging receiver as it is the only one I found that retains NFC functionality. But first, a story.
I went through 2 charging receivers because both does not retain NFC functionality. I ended up with the Qi-Infinity as my third and final charging receiver.
I have a RAVPower Charging Pad (RP-WCN7) which seems to continually charge my Note 4 even when full.
So, for the interesting part.
I bought another receiver from amazon that says it will stop charging when the phone is fully charged.
Sure enough, it didn't do that for my Note 4. But interestingly, it stopped charging when I tested it out with a Nexus 4.
Am I missing something with wireless charging technology? Is there a protocol that the qi standard uses to send out charge status? If someone could suggest a wireless charger that shuts off automatically, that would be great!
Thanks

Hi, most wireless charges have built in energy saver that automatically go to idle mode once your phone charges up to 100%. Maybe you've got some problem with your charger. You may go to the CHOETECH wireless chargers. I'm using their Stadium Qi Wireless Charger (3 coils) that I had months ago, but I just saw a new wireless charger (3 coils, lighting sensor) that worth a better shot for $20. Hope it helps.

+1 for the CHOETECH Stadium. I have two of them, and a FoneSalesMan SlimPWRCard in my Note 4. Phone stops charging when it's at 100% - and no sounds so it's good for using at night. Thanks for the link to the new charger, looks good, but the review says 1 coil?

Hi, thank you! You are correct, it's a single coil charger.
I found they're talking about a Fast Charger one. But I'm not sure whether a Fast wireless charger works with our Galaxy Note 4.

Hello,
I have the SHIELD Tablet, and like many of us had problems with a laggy touchscreen when certain chargers were used. It only happened by some, but not by all.
Using a USB volt and current meter, I was able to identify the cause of the problem.
First some technical background. USB ports and chargers always should give 5 volt. Small variances are allowed, and usually not a problem. Some chargers will drop the voltage a little under load, which also should not be a problem. The current that can be delivered is variable and depends on what the device needs and the charger can handle. Too heavy a charger does not matter, too light a charger only makes the device charge slower, but no technical problems should be caused.
Now, I just yesterday received a new charger, and it has two ports, one for 1 amp of current, and one for 2.4. If the tablet is almost empty, it will try to draw about 1.7 Amps of current, and with the 2.4 amp charger, this will cause a drop from 5V to 4.7V. This also caused the touchscreen to lag.
When I used the 1 amp port it could not charge as fast, but the voltage remained at 5 volt. Because of this the touchscreen did not lag.
So basically, a charger that drops its voltage too much will make at least some touch screens of the nvidia SHIELD lag. the problem can be solved by taking a charger that does not drop its voltage under load, which in my experience means a less heavy charger then is needed for optimal charging. I recommend using two chargers, if you cannot find a heavy one that does not drop its voltage too much.
Also, English is not my first language, so I apologize for any language issues.
One problem with this theory - I've checked the exact same thing and my charger doesn't drop voltage, but I DO experience touch screen delay. My guess is it's a capacitance issue.

Well I don't have the equipment to test this but I have a Quickcharger 2.0 which came with my LG V10 and a normal charger that came with my girlfriend's LG G4 and I have had no problems with the QC but the normal charger causes considerable lag to the touchscreen as well as making my swipes inverted some times.

Incidentally, I've seen the behaviour be present and absent on the same charger: moving a cable caused the touchscreen lag to show up and disappear, depending on its position.
Its not only the Charger, the cable also makes a big difference!

In my experience, I was using the same charger for Samsung Note 4, was using a cheap cable and there was lag. Used original Samsung cable and the problem was gone.
Sent from my SHIELD Tablet K1 using XDA-Developers mobile app
This has been an issue with my Shield tablet that has absolutely driven me insane. I've searched online from time to time and there doesn't seem to be a lot of information out there about this, which surprises me.
My experience with touchscreen lag is significant when the tablet is plugged in. The tablet is UNUSABLE...let me repeat...UNUSABLE. I've used the original charger/cable, a 2.4 amp output charger with 20 and 22 gauge cables, and a Quick Charge 2.0 charger with the same cables. The only time I don't experience any lag is when I use the Quick Charge 2.0 charger (imagine my surprise and delight when I tried this!). I'm kind of anal about my cables so I ensure they are good ones.
I've been noticing another interesting experience I have been having.
I bought the PWR+ 3.5 amp charger, and I have no touchscreen lag issues on the STOCK 5.3 ROM. I used to have a Samsung Quick Charge cable and wall adapter, but sometimes it would simply not charge.... it was inconsistent.
So the PWR+ works with the stock ROM, but on ANY custom rom and kernel I've tried so far available on the XDA forums (great job btw devs), I get lag. I'm not sure why this is the case and its the biggest thing keeping me away from custom roms. Even flashing the original kernel and dbt file doesn't resolve the issue.
Post Android Pie update I've noticed issues with the PD rapid charging. The original usb-c cable that came with the phone no longer works but I had no issues with the replacements but now occasionally I have to unplug/replug or reboot my phone in order for it to activate the "rapid charge" mode. I've tested this at various battery levels, power supply's and in general it doesn't seem to activate like it used to. My 3rd party Auckley charger was great but now I get more out of the 2.4A USB-A port than the USB-C PD/QC port.
I've heard the rapid charge feature hasn't been working correctly on Pixel's post update and was wondering if the causes were related? I'm hoping Essential responds to my concerns and if the issue is widespread issues a fix.

I did a clean install of P and I am not having issues.
Factory and 3rd party cables and chargers work fine.
Similar problem here except OEM cable works fine; 3rd party cables are having the problems you describe.

I suspect some 3rd party stuff is not really PD capable.
3rd Party VS OEM
I accept that some 3rd Party stuff may not be up to the same standards as OEM stuff but they (different USB-C cables) worked before the update and stopped after... If it was a single type/set up I would accept that as the cause but in this case it has happened with several different ones so I'm thinking it's a broader issue.

There is a handshake protocol and maybe there is a more strict adherence to the handshake?
I'm experiencing the same issue. Some PD chargers work; some do not. I just got my PH-1, so I'd never charged it prior to Pie.
Make sure your PD charger can do 9v and 12v for fast charge.

Finally yes I have this issue almost thrice a week dunno what causes it considering to factory reset.
got the same issue I have to plug in and pull out the cable one, two, three times until fast charging works!
Same issue... Using ampere to test and a few cables as well.. same issue.
I have some issue, how to fix it?
i'm going to revive this thread quick. Just got a Aukey PA-D1 (https://www.aukey.com/products/dual-port-30w-pd-wall-charger-with-dynamic-detect) and a matching type c-type c cable from them. plug the phone in and it goes from charging slowly, to rapidly, then drops completely, then restarts that whole sequence over and over. usually a restart will fix it, but its every time i plug it in. has anyone found an answer as to why this does this?
btw, running latest android 9, with june patch....
It happens to me only with power bank that supports PD.
It says charging slowly, normal, rapidly and disconnect.
Tried it with Galaxy s8, Galaxy note 8, lg g6 and it charge them great, without disconnect and with speed charge.
Also tried few cables, original cable and 3rd party who supports PD charge.

This has happened to me since I've owned the phone on one of my car chargers I own. It's just that one charger too. Issue has survived one RMA and multiple cables being used. In general I just plug it in and check in couple minutes to make sure it says fast charging and if not, unplug and replug it in.
Who knows if it's the charger's fault or essentials fault. I'm kinda leaning essential because it works just fine on my wife's pixel but the pixel is much more "understanding" in general when it comes to chargers (like it seems to fast charge on qc 3.0 too).
Anyone on Q beta seeing this?
I have been seeing this issue with 3rd party charger for months. I am wondering if anyone who has tried Q beta saw this issue resolved in Q beta.

My understanding is Quick Charge is broken...
So if the wallwart supports QuickCharge in anyway... It's trouble...
It has been that way for me on every iteration and security patch going back to 11/17 or so...
Somewhere... Way deep in the forum covered by ETA requests and useless banter... There's an article linked about how the PH-1 requests too much voltage from QuickCharge and forces it to reset...
This is an issue at the hardware level... And the only workaround is to make sure your charge brick does not support QC at all

Just figured I'd chime in as well. I'm experiencing the "Charging / Charging Slowly / Charging Rapidly" issue with my USB-C Car charger. One a Verizon branded and one an Anker branded. I know the Anker one is a "Q.C." one because it says it right on the device - but with the Q.C. enabled one, I only get "Charging Slowly" on it (so slow in fact, that the battery actually drains on the device). With the Verizon charger, I get the "charging loop".
Q beta 4 resolved this issue for me but it's back on both beta 5 and 6 . I've tried the OEM charger, a Nexus 6p charger, a OnePlus 7 charger and a Samsung Galaxy note 9 charger. They all cycle between charging slowly/ charging/ charging rapidly and not charging.
Has absolutely nothing to do with third party cables not being up to Power Delivery specification (at least in my extensive experience with this God-forsaken no end in sight charge speed bug. I've had absolutely asinine experiences with it myself where I've routinely {more than 25% of the time) had under 1000ma upon fresh plug in with battery below 30%. Also worth noting that I've seen the problem albeit less often pop up with USB a to c cables and ports as well.
I just got a Note 20 Ultra and the wireless fast charger I've been using (including on S20+) will not work. I get a notification that says: Fast wireless charging unavailable. This fast wireless charger isn't compatible with your phone, so you're charging at standard speed.
This is just all kinds of annoying because I have lots of third party wireless chargers and it seems like Samsung is pulling an Apple move by making people use their own accessories. Is there some way around this so that I can fast charge with the chargers I have? This is the kind of thing that pushed me away from Apple and Samsung is doing more and more of that same kind of crap. Not sure I want to keep this phone if I have to replace all my chargers too. Especially considering how expensive Samsung chargers are.
Figured I would try, do you have fast wireless turned on?

It's an update Samsung sent out, no more fast charging with 3rd party chargers, only genuine Samsung chargers can fast wireless charge now (So I've read)
Not true. You can still fast charge on third party chargers you just have to find one that works. I had to try different one till i found one that worked. Also look at reviews and see if anyone confirms it working on a note 20 ultra

Samsung may have tighten the protocols because of 3rd party chargers causing undesirable issues rather than malicious exclusion.
If the charger/cable meet the protocols they should work.
With the newer fast charging I just stick to OEM. With the wattage and heat on these phones it is better to mitigate any risk.
fast charging (~10W) is super old now and it's sad Samsung is so behind competition. Anyways, i have collected many Qi chargers in time and I can promise you: Note20 or recent Samsungs will rarely work with 3rd party chargers. No 15W, no 10W, just good ol' 5W (4+ hours). Frequently even 0 watts (including Samsung chargers!). It's like Oneplus charging - least compatible of all, and there's just one 3rd party cable and one usb tester that works. The charging wars continue. Samsung customer is always the loser. Samsung customer has to fight and pay a lot to get laughable "fast" wireless charging like it was 2017. Same with wired charging..
Bringing this thread back from the dead ..... not long got a Note 20 (refurbished) and starting to get annoyed at the way my car charger won't actually charge the phone - just maintain it's charge level. The same charger will charge a Note 9 and an S7 much faster. I've read that Sammie managed to put out an update to stop 3rd party chargers working so well and see pointers to chargers that will work but has anyone managed to figure out a software fix for the issue? As in any devs. managed to figure out how to get around the issue?

If the display is on it will charge slowly or not at all, fast charging will not engage. If too hot charging may slow or disengage.
If too cold fast charging will not engage.
All in order to protect the Li from plating or worse.
