Does reverse charging work while the phone is being charged via usb? - Samsung Galaxy S10 Questions & Answers

I have a Galaxy Watch, and if I go on trips, it would save me from remembering or bringing the wired charging dock. Before I go to bed I can have my phone charging and my watch or buds charging at the same time. Can anyone confirm?
Thanks

I have been wondering this as well. I hope so as that would really be the only time I would use it.

I have S10+. I tried my S8+ on S10+ while S10+ being charging. I assume it works.

So charging worked properly or it is an assumption?

I guess it worked fine.

I read somewhere that it does charge while charging. I suspect that phone charging will slow while doing that.

It does. I saw that on a YouTube video somewhere.

Problem with wireless charging

Took ZV6 a couple days ago, but I don't think that matters.
Last night, everything was working fine. I was wirelessly charging in my truck, at my desk, and on my nightstand.
At work today, it won't pickup my wireless charger. I've tried multiple chargers, I've tried 2 different backs with NewWisdom chargers in them. Nothing. Thoughts?
EDIT: NFC still works
No thoughts on this?

The only thing that I can think of is your wireless sticker moving ever so slightly from the contacts? My charging is fine.

Wireless Charging Stopped Working

Wireless charging on my bundled Wireless Charging Convertible pad stopped working yesterday and I haven't been able to get it to function again. Starting yesterday morning, the charger pad wouldn't recognize the phone at all, case off. After playing around for a while, including clearing the cache from Recovery, I can get the charger to recognize the phone, the phone now says Fast Charging, but the phone continues to drain over time vs charging. Some users in the past have gotten a Charging Paused message, by I don't get that message unless I remove the phone from the charging pad.
I've tried two Samsung Fast Charging AC adapters, the USB cable that came with the charging pad, and an Aukey cable, same results.
Has anybody else experienced any issues like this with their Note 8 or convertible charging pad?
Edit: MST also doesn't work, I'd guess it's related.

Only way to diagnose this would be by trying to charge the phone with another wireless charging pad.
Does your phone charge normally through the provided type-C cable and power adapter?
Found a non-convertible style wireless charger a co-worker had, which charges his S7, but doesn't charge mine Note8. Could it be the phone itself?

I would not rule that out. I would take your charger and phone to a local best buy and test against a display, if your charger charges other phones, then it's your note. Or try your carriers local corporate store, they probably would help as well.

Well I can verify that the phone is the problem. Note 8 won't charge on any wireless charging pad, and Samsung Pay's MST also stopped working at the same time. Going to contact Samsung and see what can be done, hope I don't have to set up a new phone yet again.
This happens to me alot. I have 2 wireless pads, 1 verizon (from my note 7) and the Samsung Fast Charge.. It just stops working randomly.. Reboot the phone, then starts working fine again.
I still use my Nokia wireless pad....I found it charged the time as the Samsung fast wireless charger.
Probably not much help but are you on the latest firmware? When I updated mine it said the new changes were for the camera & wireless charging but of course no other details.
I haven't had a problem with mine though even before the update. I don't have the bundled charging pad though, I'm using the older Samsung fast charge pad.

Good luck. Same problem with my s8+, samsung says its not the phone. But it is. Every problem with a warranty repair is like pulling teeth with samsung. I wish LG would up thier phone game just a little, and I would never buy another samsung again.

is this after the 9/25 update? Mine stopped charging after that update on both Samsung fast wireless chargers I have.
I have a Note 5 that will not charge on either a normal wireless Samsung charger or a fast charger Samsung pad IF the protective case is on it. This started just this week. I can remove the protective case and then it will charge.
I don't recall getting an update on or after 9/25. N950USQU1AQI5. I did get an update that improved camera performance, but it was a week or two ago. Just performed a factory reset, no luck on a fresh install. I can also confirm MST on Samsung Pay still doesn't work after factory default, they have to be related. Frustrated I'm going to have to deal with warranty. After two Note 7's, going through another Note 8 is beyond frustrating. QA @ Samsung could really use some work.
So Samsung has agreed to repair/replace the phone, but I'll be without the phone for 3 weeks. Since I just switched to Verizon, the only old cell phone I have won't work. Since I bought from Samsung.com directly, Verizon won't help. Samsung.com refuses to provide a loaner/temp phone or to cross-ship a new one. Their manufacturing defect means I have to bear the burden of their problems. I wouldn't care too much about wireless charging, but MST is also affected, and I love MST.
Lesson learned - Never purchase a phone directly from Samsung.com, even if that means getting a discount or promotion.
I just sent my Note 8 in for the Same thing. After 4 weeks of ownership it stopped charging wirelessly.
The Samsung Rep I spoke to seemed to think it was related to the NFC, something about NFC being involved in the wireless charging some how. So MST must be the reason.
I sent my Axon 7 for warranty repair the same day. Luckily I still have my LG V20 and Nexus 6P (with is horridly degraded battery), so I have backup phones.
I'm on firmware AQI5 and wireless charging has stopped working completely. I've tried Samsung and third party chargers, all of which worked last week and still work with other phones. So I'm thinking it's a firmware bug...

Describes my problem almost perfectly. Now on my third VZW note 8. First one charged fast wireless for exactly a month. Second one, worked for eight days. Now the third, 7 days.
All four of my offical Samsung wireless chargers quit recognizing at the same time. FYI; two charge pads and two charge stands all fast wireless and purchased thru out my time with S7 Edge (went thru 2 rounds note 7). To add to that the new promo convertible quit at the same time as well.
Pretty darn sure it's in the phones. The latest phone charged wirelessly to 100%, then nine hours of driving later, no go. Pulled my UAG Monarch off, still nothing. Tried the other wireless chargers, nothing. No new apps or settings changed during my drive. Thoroughly confused.
All three of phones were put thru the ringer with VZW tech support: check this, check that, safe mode and the end all factory data reset, still no go every time. I contacted Samsung directly once, what a waste of time. Their only answer was send it in for evaluation and possible repair or replacement, you should have your phone back in a couple weeks. Second go around with Samsung, I was transferred by VZW. Their answer that time was; send the phone and the charger. Had to reply, which charger, all of them? Samsung, then told me all of my older chargers aren't compatible with the note 8 and must have damaged it. That style of charger is still readily available and advertised as note 8 compatible.
I've never used NFC or MST, so I can't comment on that.
All three phones fast charge on the wire.
Can anyone verify compatibility or lack there of with all these fast wireless chargers I own?
Willing to try anything at this point. I would dump the 8, if I didn't use the pen so much. Been using note phone since the 2.
It's the phone. Contact Samsung for warranty repair.
Just got mine back and its working fine again.

According to the rep I spoke to it was to do with NFC, as it is somehow involved with the wireless charging process.
Sound a bit strange, but others are saying that wireless or MST payments are both affected. So I guess wireless payments and wireless charging are somehow connected.

I don't think it is. I got them to do a warranty replacement, and my new phone worked fine. But, as soon as I wiped my old phone in preparation for returning it, it started working as well. Then, a couple of days later, my new phone stopped wireless charging.
Right now, I am just hoping that the Oreo update fixes it.

P30 Pro | Galaxy Watch Active and reverse charging

Hi all
Got today the P30 pro after the OP6T, happy with the change
One of the reasons i've switched is for wireless charging and the reverse wireless charging - but even after I turn this option on (wish there was a shortcut) it won't seem to charge my Galaxy Watch Active.
Someone here knows what to do? I tried it on an S10 and it worked flawlessly
Thanks a lot

I also want to try that out, when I get my P30 Pro today I will update my comment and let you know if mine works!
There has been several reports about galaxy watch not being able to reverse charge on a mate 20 pro (and even some third party wireless charging pad)although technically the watch should charge on any qi standard charger. Not sure what the culprit is but the watch seems to only work on samsung own devices.
I just bought a p30 pro as well and is holding back buying the galaxy watch exactly because of this reason. I wasn't sure if it will work.
Have you tried moving the watch around the back of the phone to find the "sweet spot"? I'm very interested if you will be able to make it work eventually because this could be a deal breaker for me.
Please do keep me updated if possible. Cheers!
Not woking for me
Can confirm that it does not charge a Galaxy Watch active, however it does charge galaxy buds...very strange
@gravityz3r0 I've tried several times .. with/without a case, on any place on the back of the phone. Simply not working. It's a definitive bummer since the watch is very good
Galaxy Watch works only with the original Samsung charger!

Except its not.
As I can not get the Galaxy Watch to charge with anything other than Samsung chargers/devices.
It's working. My Mate 20 Pro can charge Galaxy Active 2. Just move it around the back of the phone and wait for a few seconds at each spot
something weird happened with me.. i've tried many times t reverse charge my watch but nothing happened then i have read here that i have to wait a little seconds then after 10 seconds it get lights on with charging sign then 3 minutes a pop up appeared that the watch is getting high temperature and stopped charging and phone also got hot .... any one faced that before ??

Fast charging is gone

Anyone know what I have to do to get fast charging back? I have the option enabled in settings. The cord is good, my wife's phone fast charges just fine with it. I've soft reset the phone, cleared cache, and just about any other option I could find on the web. So weird cuz it was working fine not too long ago but just noticed now that I can't get it to work.
Try cleaning the usb port on your phone. i had the same problem, just cleaned it out with air.
Thanks but been tried that. I work in Audio/video so that was one of the first things I tried.

Are you able to mount the phone as storage on a computer, or able to access a USB with the OTG adapter? The charge port on this phone isn't the most robust and a few people have had problems with then failing.
No issues with any other stuff except fast charging. The phone charges fine but just say fast charging and takes forever. It's so weird cuz in my car my phone would barely charge when hooked up to USB in console, but then soon as I lost fast charging at home it started fast charging in the car. I just don't get it

Well luckily normal charging and USB still works so it's not the worst. At least your battery will last a little longer now?
My advice would be install an app like accubattery
https://play.google.com/store/apps/details?id=com.digibites.accubattery
It will show current when charging.
Fast charging being displayed by Android only seems to indicate fast charging is enabled rather than actually occurring.
I find when fast charging is occurring with standard Samsung charger, but not original cable it will show approximately 2800 mA.
It did seem to be below this rate a few months ago when ambient temperatures were higher and battery temp got above 36 °C
I also bought an unbranded charger cable that has an led that illuminates bright when high current charging and dimmer when charging at lower rates.
Probably defective . I've read issues on here about fast charging no longer working and it had to be repaired by samsung.

Ive had this problem with all my samsung phones since galaxy s8. I dont know why after some months the phone loses the ability to fast charge (it happened to my s8, note 8 and currently note 9)
Enviado desde mi SM-N960U mediante Tapatalk
I finally replaced the usb-c port
I had the issue that fast charging was gone and it charged very slow sometimes. I did many searches and did everything I could do. none changed anything. finally I went to Samsung and they replaced the port.

Was ur phone under warranty still?

It was. Now I am a bit skeptical about this USB-C port thing. I take good care of my gears. Especially this one that cost me an arm and a leg. I want to do a survey if all the manufacturers' type-c port is prone to get damaged like this easy!
I would take your device to a Samsung Service Centre and let them take a look at it.

Adaptive Charging Issues

Has anyone with a Pixel 4a 5G managed to get Adaptive Charging to work properly?
I know it only works at specific timings.
Ok, so say I set my alarm for 7am and I put it on charge at 10.30pm, it states that it is Adaptive Charging and will be fully charged by 7am.
However, when I awoke at 2am it had fully charged already.
Google stated to try it in safe mode which I did but it was still the same outcome.
Is anyone experiencing the same?

yes, slowly, but at the same time the battery charging process is not interrupted, so even at low amperage, the phone can already charge at 2-3 a.m. (4-5 hours after the start).

Adaptive Charging still not working. I thought the February patch would of fixed it but it hasn't
If the firmware is stock and the kernel too, then adaptive charging works. Read carefully how it works!

It's not that simple.
Charging for the right amount of time and at the rate charge current will make or break your battery over the long haul.
From a pixel 2 user with a bad battery from overcharging.
Now that I have the 4A 5G, which came in the mail today, directly from Google I guess I'll dare to take a heat gun and try to pull the Pixel 2 apart (which I guess is quite difficult without breaking anything) and replace the battery ... but I sure wish that I had had either A one of those USB chargers that shuts off automatically or B that the phone had adaptive charging of some sort.

This is what Google states. To me it was sold to users completely different to wait they say now.
