Note 9 - S10 Official Samsung fast wireless charger - Samsung Galaxy Note 9 Guides, News, & Discussion

Hi there!
I would wanna know why is that my 2 phones (S10, Note9) behaving the same exact way on 2 different Samsung fast chargers - Wireless Charger Duo and Wireless Charger Convertible.
Whenever I try to charge, after like 5 mins, the charging rate drops from 800-840mA to 0-200mA, and it takes around 4-5 hours to fully charge. I tried different official samsung bricks and cables (the one that comes with phone, one that comes with the duo, one that I bought seperately as adaptive fast charger brick etc), ALSO third party bricks and cables, no change whatsoever, behaves the same way.
The phones reach around 38 Celsius the first time when it charges with 800mA, then drops down to 36 Celsius with 0-200mA.
I'm guessing its the heat sensor in either the charger or the phone, but it's ridiculous...I have an ambient temp of around 25-28 celsius since it's summer, but even a 40 celsius on the phone or the charger shouldn't be a problem in my opinion...(PC cpu-s can operate on 60-70 celsius nonstop without even crashing)
Thanks for reading

samsung charging cables are trash.
for me if phone is under direct sunlight at an ambient 30c it will notify me of overheating and stop charging.

Well sorry, but that's obvious, the outer parts of the phone (aluminium and plastic) can get around, I'd guess, 80 celsius in summer in direct sunlight at midday...
I'm obviously not trying to wirelessly charge my phone in direct sunlight, and I advise you the same so thanks for that piece of information...

jd14771 said:
Do you have a case on either phone by chance? since were pointing out the obvious here lol.
Click to expand...
Click to collapse
Of course I do, but that actually doesnt affect it, tried without the cases...
I really think it's the "heating", but the real interesting thing is that I think before the june patch, it didn't matter how hot it got, it just charged with full throttle until about 90%, the dropped to half (500mA-600mA)...I only experienced it after that update...
So noone has a solution I guess...is there any way to overwrite that sensor coding to 39 degrees?

jd14771 said:
Having a thick case can absolutely effect wireless charging, so that's why I asked.
Now you say that it's been since the June patch that it's been acting like this, and Samsung could have very well limited wireless charging under heat.
Due to the harsh reality that is the note 7, these seem to be sensible, required limits to charging. I would not help in changing that hard limit on battery temp current limiting, nor do I suggest anyone else for it's a safety risk.
Is fast charging on? (Assuming it is)
Turn of fast charging and see if the charge temps allow for uninterrupted charging.

Well I just made a small test, seems like it only fluctuates a very small amount fast wireless turned off - 380-440mA, and the hottest it gets is 35 celsius degrees.
It really seems to me that when temps hit 38celsius (I dont know which temp sensor is that ,I know its not the cpu part, it's the one shows in apps like Ampere), it just almost disconnects the charging, which is interesting, if it gets just around 38c with 840mA, it just should lower the amp input a bit, like 700mA (somehow, I don't really know how it works, maybe it's either fast or normal charge, not like an adjustable value).
Maybe someone from Samsung team will read this or similar, and make it work
And yes, I do remember the S7 misery and yeah of course, especially during summer, it must be a concern (probably that's why they included this in June patch)
But then again...I bought a topnotch phone, official fast charger, and a few degrees warmer, makes it charge 0-200mA... which is less the half of normal wireless charging

jd14771 said:
You bought a top notch phone, do you want a top notch fire started instead? Lol
I can understand how frustrating it would be to not be able to wireless charge at all like in your situation.
So did turning off fast charging work for you?
Click to expand...
Click to collapse
Come on, it wouldn't start a fire, like I said, it wasn't like this before the june patch (maybe may), I actually did measurements in between fast wired, fast wireless chargings, official and unofficial brands to see if I would need to buy the samsung stuff for 500% that does the same as an offbrand charger, and actually yes, official wireless chargers for samsung do charge the phone around 10-15% faster, BUT I also looked at temps, during springtime, it was well above 39 celsius for the most part of the charging time(it just kept charging full throttle)...
And again, yeah, turning off fast wireless charging goes flawlessly.
Also, did a small test again, wired fast charge, around 1100mA, phone gets around 39-40celsius, yet that keeps on going, no "charging-throttle"...it must be something to do with the parameters and values added in the wireless coding.

I'd post on the samsung forums instead of xda if you really want actual visibly on Samsung's part. dont know why people continue to report issues and expect support from xda when issues as these are clearly something to bring up to the phone company.( screen issues, camera issues etc, all are reported on xda and i suspect only a small amount actualy post about it on samsung forums)
also did you check if fast WIRED charging also has the same issues/behavior?
if so, you know its not related to the type of charging but something newly implemented.

Battery degredation by heat is a real problem for lithium. And the fire risk comes from the fact that they can create their own oxygen and putting them out is near impossible unless you have the proper dousing chemicals.
Wireless charging is know for producing excess heat..
Fast charging is know for producing excess heat...
Put them together and you have a hot phone. It sounds like Samsung patched a flaw in the charging system that can lead 5o battery issues over charge cycles.
On one hand The only way to really test this is for you to flash your phone to an earlier OS VERSION and see if this is in fact the case.
On the other hand at least you know you can turn of fast charging in order to produce stable wireless charging currents. I

I would have flashed an earlier, if it was possible, you can't downgrade official firmware since about a year ago, maybe even more. How come you seem to want to show you know a lot, you dont know this?
Once again, I'm sorry, but it seems to me you only wrote here to argue with someone, look at my and your first post.....
You didn't help, just tried to show (for any reason) inferiority by arguing with literally everything I stated.
Now I dont care for that...
Are you a Samsung employee? I know a lot of the software engineers from Samsung and from Google are here to learn, experiment with mods, features, roms etc.
Main point I already made, in an ambient temp of 27 degrees, the 100 dollar fast wireless charger takes 5 hours to charge, which is ridiculous value, and you cant state any reasoning for this, since a few months ago it worked as it should.

People come here for the reason I stated above...a whole lot of software engineers working for eg. Samsung learns a lot here, most of the implemented stuff year by year in official firmwares first appeared on xda as a mod, or as a part of the rom, so if I want to overcome a problem, I'd rather get info from here than from a lowlevel technician/communicator from samsung....also, most of the time, they reply with a "Have you tried pulling out and plugging in? Yes? Then turn off then on, youre welcome!", since they won't acknowledge on official forums what are the flaws in their products, so no solving either...

i get your point and its a valid one. but id still copy paste your post over there. if more people chime in on their site and creates a stir, maybe it will get things going.

jd14771 said:
This in incorrect. Completely incorrect. For both the Exynos and the Snapdragon model. You never stated what version phone you have.
I have the US snapgradon note 9, and i can upgrade and downgrade to ANY available OS version.
For the Exynos variant, you can downgrade so long as the version you are downgrading too has a bootloader version that is the same version. If you are on the current OS version from 7/10, then you can not downgrade. But if you were on Pie 6/03 you could have downgraded all the way to oreo update from 10/11/18.
For why you want to call me out is understandable. im not telling you what you want to hear.
That is not even close to the truth. for anyone who looks all i asked was if you had a case or not- because a thick case will limit or stop wireless charging all together. All you are showing is your lack of understanding or patience because i have not fixed YOUR problem. i find your tone insulting and i hope you can fix this on your own from here on out as i am done trying to offer my help for free. you are the one being rude.
I have already stated two reasons for this. you just have not accepted them. that is fine.
also, i reported your post, so in the future i would try to keep your banter and insults to 0.

You cannot downgrade because the bootloader gets updated...you actually ran into some sort of "self-oximoron"
I call out anyone whom is arguing with me for no reason, don't need that sorry, I've grown up
Why, what do I want to hear? I tell you, maybe someone knows that there is a certain combination of settings/apps that casues this, happened some similar stuff before in smartphone history....I've been using custom roms/mods since 2012, seen/experienced some weird stuff
All you asked was what case I use? Come on..... everything is written here - as long as you won't delete your responses, everyone can see you did not try to help
Done trying to offer help for free? What if I pay? come on man, you sound ridiculous You did not help - otherwise, please, quote your solution to my problem
Also, you replied here, I did not ask for YOUR specific help, I asked a community. Do you know where you are?
Report me all day, haven't written anything offensive...you probably never looked up what offensive means by either law or forums rules...
Also, some literature....
When you write "I would...", its like writing "If I were you, I would do this and that". "I would...your banter..." doesn't make sense.
Have a nice one, thanks for telling me to not use thick cases when I'm wirelessly charging

jd14771 said:
First off, you never specified what model you have, and still have not.
Second, as you can see below, the BOOTLOADER is currently on V3 for the N960F, but only the last update is V3. If you are on V2 you can absolutely downgrade all the way back to Oero from 2018.
And if you have the american Snapdragon model, there has not been a BOOTLOADER update so you can flash any version you please.
So i have no idea why you keep saying that the bootloader was upgraded over a year ago and nobody can downgrade. not sure where you go that misinformation, but i am clarifying for any poor souls reading through this to see the truth.
feel free to quote what i said that was rude. You can't delete posts, and i have not changed any of mine besides spelling typos. Mods will confirm this when they check this since i reported your misconduct.
i will report you if need be as that is what we have been instructed to do when users act the way you are acting. The only reason i am posting is so that anyone else reading is not misled by your false claims about downgrading, or my conduct.

Couldn't be bothered to read through the arguing (you guys should really grow up) but thought I'd chime in with my testing results, I check the power my Ravpower wireless charger is using so will be different to however you're getting your figures. I'm seeing 9V 1A until it hits 38C and then it drops to 9V 0.5A and then it jumps back up to 9V 1A after the temp drops down to 36C. I have a USB desk fan that I usually point at the phone when wireless charging and that keeps the phone within a few degrees of ambient.
My phone is a N960F running the July firmware.

Flashing ROM while charging..

Normally I would fully charge the phone before flashing anything, but since Cyanogen just released his new 4.1.6, I wanna flash it right away ! My battery has 67% left. Can I plug the phone into the charger and flash it ?
Thanks in advance
Yes, you can charge your phone and flash at the same time. I always do.
I can't tell you from a tech perspective if it's okay but I can speak from personal experience that it doesn't do any bad. I do it all the time
the only reason they say to have a fully charged battery is so that during the flashing process your phone will not die and possibly leave you with a brick but as yellow (ffff00) said you can flash with your phone charging. i always do too.
Lol, yes you can . Have fun with new version.

oooooh you say it so sternly. how do you know have you tried flashing a rom when you have 31% and it went fine, but when you did it at 30% it died lol. actually i have read this as well.
I never flash while charging. I'm too paranoid of power surges causing a flash to go ugly. And I've had equipment on good quality surge supressors die from power surges before so I don't trust those either.
Therefore, battery power flashes only for me
Flashing with the cable is always the best way to go.. If something goes wrong you are going to have to plug it in anyway
But i have not had any problems thus far.
I see most of the Rom now request the you should have atleast 50% battery life left

Replacement = Even more problems.

Had a n6 with half purple screen and had it exchanged.
This new one is horrible ..
It seems to get really warm compared to the other and when it does, boy does it lag. Just typing this out, it's lagging.
I also noticed that my Bluetooth has "silence" spots while listening to music. Every 2-3 minutes, it will stop for a split second like it can't buffer, even if the music is on the device.
Another thing that may just be me, it seems the keyboard doesn't predict as well, like it's not even touching the keys I'm swiping.
Lastly, half the screen is white and half is a really yellow color. Very irritated by this device. Makes me want to throw it against a wall.
Your first problem can be resolved by using a custom kernel that does not use mpdecision. Mpdecision is known to be power inefficient and sends your CPU to be sitting in wasteful frequencies causing your phone to generate additional heat. My phone became really warm with mpdecision on.
Secondly, I don't use bluetooth so I can't comment.
Third. That isn't a N6 problem, its a problem with the software of the keyboard application that you're using. SwiftKey works great for me.
Fourth, can't really comment on that. My screen looks good, your phone should be uniformly the same color, you can try changing RGB and see if it would do anything. I recommend turning off adaptive brightness.
Good suggestions I suppose.
Only problem with those, I'm not gonna root or use a custom kernel. The last n6 only had a faulty screen and no other problems. That one didn't need any custom root activities.

If you don't root, or use ROM's then why post about it on a developer forum? I'm not trying to be rude just wondering why here. If it has more issue call moto and have them send a new one. My RMA phone is fine 0 issues so far and I'm happy with it.
This is a user forum as well as a developer forum.
I'm posting here to show there is problems with these phones.
Why does it matter to you?
If you are having those problems on stock, and don't want to root/etc, then your only option is to return it again. Pretty simple.
If you are looking for confirmation that your experience isn't 'normal' on the stock phone, I can confirm it is not.

I'm not trying to argue at all I was just curious. I would have the phone replaced if you want to gave those issues fixed without modifying the phone. Best of luck with the issues because it's not fun when you can't fix them.

I scratch my head also. XDA is a developer's forum. There are tons of other sites more suitable to those not wanting to root/ROM it up.
Sounds good. Let's discuss dbrand skins and the such.
I doubt this has anything to do with memory leaks or anything that's been discussed on lollipop.
I'd say you have a faulty SOC and I would replace it. My wife had similar issues on an S5 where it would stutter and fall behind almost and get warm. The icing on the cake was while taking video, normal 1080p video, and it would drop frames like crazy. Maybe 22fps or so was al, it was getting.
I actually agree with 20degrees on this one... There are tons of non development/customization threads on here, and XDA has a pretty knowledgeable user base so it is a convenient one stop shop for info.
People just need to ignore/keep their comments to themselves in the Q&A and general sections if they have nothing constructive to add to the topic of the thread.

Crazy battery drain on note5

Hi there. One day, I went to sleep with 80% battery. I woke up with the note5 off... no more battery mmm the day after I turned it off before sleeping at 40%. Guess what? It did not want to turn on... no more battery. 100% stock Android never rooted almost still new .. turning me crazy
Do you have ideas/ suggestions?

Mine is rooted with all the deepsleep fixes but still the same thing happens to me. And I cant find whats causing it. No wakelocks, no apps that would drain. It just seems like the battery acid magically vaporizes overnight. If someone can help us with this issue, please do. I'll be grateful.

If you look at the graph, till 10pm the device was fine. Then I checked for the time on the phone and let it just sit there. You can see the steep part where it's draining like hell. Then it stopped. Then it started draining again. I haven't touched anything on it. Just checked the time by clicking the home button. It just happened. I have no idea what's going on. I swear if this doesn't stop after marshmallow I'll snap this phone in half and throw it in the trashcan. There is no way someone could use this thing with this type of issues. I'm done with samsung.

Well, you see this whole problem comes from the fact that samsung doesn't open its sources to developers. No one knows what's really going on underneath the system. What kernel is really doing and what hidden services the rom has. The developer support for exynos devices is very little(thanks to those who are still trying despite the closed source code). My nexus 6(which I'm currently using instead of the note 5) had poor battery life. But thanks to open source kernel and aosp, now my n6 lasts me days with single charge. If anything happens, devs are fast to patch it up. So i think jumping straight to iphone is not really necessary if instead you can buy devices that welcome the dev support and community and are also more fun to use than iphone.

Yeah, no that's not it. I use the original fast cable charger- the same thing, and I use the wireless fast charger(yootech) - still the same thing. I don't think it's a hardware issue. I hope it's not, cuz I got no warranty on my N920C in the US.

I'm not sure to be honest. There are people in this forum that also have 920C and not many complain either. How would we know if it's hardware or software?
I charge mine overnight as I get to the end of the evening and its on 20% max. I will try to charge mine when I get home this evening and see what happens overnight off charge........I suspect the wifi will drain the battery as a minimum. Have you tried it with wifi off?

Hi there. One day, I went to sleep with 80% battery. I woke up with the note5 off... no more battery mmm the day after I turned it off before sleeping at 40%. Guess what? It did not want to turn on... no more battery. 100% stock Android never rooted almost still new .. turning me crazy
Do you have ideas/ suggestions?

Did you rooted your phone ever or always stock? Actually i just try to understand a theory real or not??
Peoples talking about a chip, which is cracked when you root your phone and never let you reset your knox counter? and same chip, causes deep sleep issue! i want to understand, if deep sleep issue just for rooted phones, then this theory maybe true and this is so bad for samsung!!! but if same issue happens to completely stock and original phones (i mean non-rooted!), then this theory is a crap!
1) Do you facing this issue with never rooted phones?
2) when starts to drain your battery? after an update or install an apk?

As per their own statistics in the Battery Menu, I have no app that is "over consuming". As you brilliantly explained before, maybe Samsung is just not showing all the info? I might bring it to an official Samsung Store and ask them to change the battery at my own cost (even if it is still under warranty, because they will never replace it for free if they do not clearly identify the problem).
And if the problem remains, yep, I might become a youtube speaker showing how long a Note5 can survive in a washing machine.

Don't pay for the battery replacement. Tell them the issue and show screenshots. Ask for a solution. If they can't identify the problem they should give you a new device. You shouldn't pay for something that wasn't broken by you.
By the way, I'll be waiting for the washing machine video if anything... that would be so satisfying.

i am in
slept with 70%, woke up off, no more battery. And you know what? I also activated the super energy saver option that turns the screen black and white with very limited apps. It was giving me an estimation of 25 hours. More than enough to spend the night right? But no. Which makes me think more and more that this is a hardware issue... Need to find some time to drop it to samsung and update you...

Let us know what happens after you take it to the repair center. I personally blame the issue on a core process that eats up the battery but doesn't show up in the wakelock detector and the battery stats. It really happens randomly which makes me think that there is some switch in the system that clicks and doesn't click back making some process drain the battery. And it's also not a deepsleep issue so makes it even harder to guess what it possibly can be.

@umudeus Saygılar
Thats kernel issue 'IMO'.. I would prefer you to root and flash a custom kernel but as you know it will trip kn.. bla bla. I've faced the almost same problem with yours(Last %23 battery had gone in 6 hours, I thought it will sleep deeply but found it dead when I woke up in the mornin ). It was my bloody first day with my phone(btw its s6e+) and boom after two days rooted and flashed custom kernel Till now(and will go on) it was sleeping like a baby when I turned the screen off. (Extra: DS Battery Saver app has good options in the deep sleep case, >>HERE<< )(For Rooted devices).
Edit: If wonder; my deep sleep time is just %3 for 7H 41Min. See the attached shots
Sounds like a kernel or hardware problem. But, can you try something that helped me before, maybe it will help you as well?
Try to charge the phone with a regular 2A charger (I had my note 2's charger handy). Believe it or not, I said farewell to battery drain on my phone. (I used the note 2's charger for a few days, and then switched back to the fast charger and everything is fine: I get ~5h SOT before the phone reaches 5%).

Something is covering the sensor on the top of the phone. Either clean it and make sure nothing is covering it when you wake your phone or disable the block accidental touches feature

Not to be a jerk but you could've answered your own question by simply using the search function in settings. Before you could fully type "Touch input" it will have narrowed it down to the setting you were looking for.
That setting search function is an awesome tool with all the options we have.

No I read that you did everything you could. The sad thing is typing on the literal text in the setting search would've taken you right to the answer.
I just wish you put as much effort in the "exhaustive search", as you put into griping about good advice..
I mean you could just take a gander at the screen shots and see how easy it is.
Nevermind next time you get a pop up that's too hard to decipher, you can make the daunting task of searching settings.
And that's how you fish.

Wow you are seriously butt hurt over this.
Literally you could've been like "wow, so many ways to do something on this phone thanks for one more tool in my tool box".
Nevermind checking the extensive manual that answers a lot of these questions. Let's not pretend this is hard info to find. It's the phone doing what it was designed to do, not some broken feature you need to troubleshoot.
I keep forgetting this is XDA, it's easier to ask for the answer right in front of you as opposed to learning how to answer the questions yourself.
I'll report back to my support group and tell them mission accomplished. Someone learned something new.
Knowing is half the battle!
...
If you pick up your phone with your hand over the proximity sensor (top of phone), you will get this pop-up. I turned the setting off and it went away but the screen did unintentionally come on while in a pocket. Therefore, it appears best to leave it on and ignore the message.
Can a mod delete pcriz's comments and androidwarriors responses after the question was answered. I think this topic was a valid question.
Samsung has switched up a lot for the better but the downside is they moved it all around. We are stuck in such a monotonous get to point A to point B environment these days the answer was right in front of his face but he couldn't see it because he was too used to the tools he always uses. I am still learning little things about this phone as I go too. I think his question was valid, seeing as Samsung experience is still quite new, Samsung experience is such a huge improvement over TouchWiz, the note9 is loaded to the gills with features and nuances and Samsung (and other OEMs including Google) having features that have trained us to a certain mindset for years. Coming back to the note line after a hiatus hasn't been overwhelming for me but I can see where coming to the note would be like a longtime Android user switching to iOS or even vice versa. For me, still using my work iPhone is so underwhelming I can't figure stuff out and I am pretty savvy with tech. iOS users can find Android overwhelming. And listening to the apologies Apple users come up with now, compared to yesteryear, when many people are finding out iOS isn't as easy to use as has been claimed, it's just what they grew up on, kind of like learning a language. There is a lot to grasp by being immersed in the ecosystem, but more to find out by asking details and learning, learning that can be turned into a tool to find more stuff on your own. Dude obviously tried and put out one more flag up for something he might not have had control over and the response was douchebaggery at it's finest. I find the questions dumb when people are asking me how do I get such great battery life and how they can do it but are unwilling to take their phone off full brightness, theme it to take advantage of OLED's self emitting pixels and are stacked to the gills with social media and email accounts because they have to be that connected and are not willing to streamline portability. Finding the sweetspot for my notifications on the note9 was aggravating for the first time in years as there are many layers to it now. I had to experiment and read about other questions to figure it out. Settings are still taking some time to get used to with main settings, app settings and figuring out where the granular settings are when they're not in places or labeled to what we are accustomed to. To each his own but pcriz obviously overstepped the bounds for a valid question.

Insane Battery Life

Hello guys!
I wanted to make a battery calibration on my Galaxy S21 5G and i made a battery test on the road.
The phone is 5 months old.
So this is the measurement from 100% battery to 3%.
The Screentime is 11 hours and 56 min. (always on wifi) & 40 min. of music streaming on 4g (9% battery).
I think the Screentime is fantastic!
I used some tweaks from here:
[DISCONTINUED] Samsung Galaxy One UI - Optimization Guide
THIS IS A SUGGESTED CONFIGURATION FOR SAMSUNG DEVICES OUT OF SUPPORT/CLOSED I - RECOMMENDED SETTINGS To Start With - Factory Reset before starting optimisations - Factory Reset after every Major update (One UI/Android) - Remove SIM before first...
forum.xda-developers.com
and the Screen was constantly on 48Hz with Galaxy Max app.
The Performance was completely fine.
Now if this is with 48Hz, imagine what insane battery life can you get on a Galaxy Ultra with 10Hz.
Thanks for the tag, glad i helped
Basically you transformed your S21 into an S7 or S8, you might as well bought a nokia 3310 to deactivate all the features of a phone, or changed brands....

It doesn't make sense anyway, so changing the brand of phone your approach is weird in my eyes, having an S21 to make it as interesting as an older generation smartphone, you might as well buy older generations. You will gain 2x more battery again. A nokia 3310 would last 1 week in autonomy, that would be more suited to your needs. Sorry

Damn, you turned off all these features and crippled the phone but left a super obvious optimization untouched.
Using WiFi calling, you can enable airplane mode, effectively turning off your whole cellular radio.
While I'm at home, my phone is always on airplane mode, so it's not looking for towers, switching networks, etc. Depending on your provider and location, it can noticeably help with battery drain, mostly in standby.
Also...wtf Norton 360? It looks like it used a ton of battery and it's such a grandma move to have Norton on your cellphone. It's just weird to remove all the nice features of the phone, for which you paid, al in the pursuit of better battery life, but leave obvious things like this in... just my $0.02
